Andrae, Columbus, Ohio, assignor to Jeffrey Galion Manufacturing Company, a corporation oft Ohio Filed July 30, 1964, Ser. No. 386,156 12 Claims. (Cl. 251158) The instant invention relates to sluice valves, and more particularly, to an operating mechanism by which a sluice valve may be released from its seated position and raised to open the flow channel, or alternatively, the sluice valve may be lowered and seated to close the flow channel.

It is an object of the instant invention to provide an improved operating mechanism for opening and closing a sluice valve.

It is another object of the instant invention to provide an improved sluice valve operating mechanism, in which a single operating element is operative to seat and unseat the sluice valve and also to raise and lower the sluice valve.

It is another object of the instant invention to provide an improved sluice valve operating mechanism in which the application of a relatively small force is sufiicient to open and close the sluice valve.

It is still another object of the instant invention to provide an improved sluice valve operating mechanism in which there is a simple adjustment for the operating element, by which the operating element may be alternatively operated to seat and unseat the sluice valve, or to raise and lower the sluice valve.

Other objects of the instant invention will appear hereinafter, the novel features and combinations being set forth in the appended claims.

In the drawings:

FIG. 1 illustrates a sluice valve installation, including the operating mechanism of this invention;

FIG. 2 is an elevational view, partially in section, of the sluice valve operating mechanism;

FIG. 3 is a sectional view of the sluice valve operating mechanism, taken on the line 3-3 in FIG. 2;

FIG. 4 is a sectional view of a portion of the sluice valve operating mechanism, showing the selector in its first position; and

FIG. 5 is a sectional view of a portion of the sluice valve operating mechanism, showing the selector in its second position.

In the drawings, there is illustrated in FIG. 1 a sluice valve installation in a flow channel 10, which may be formed of concrete, at the top of which there is provided a floor 11. A transverse wall 12 is formed with a flow outlet 13, which is closed by a sluice valve 14, of which the valve member is seated against the flow outlet 13, thereby closing the latter.

The sluice valve 14 includes a valve actuator 16, which is connected to the valve member 15 by a plurality of cranks 17. The valve actuator 16 is raised a short distance to rotate the cranks 17, thereby disengaging the valve member 15 from the flow outlet 13 by lateral movement of the valve member 15. Thereafter, the sluice valve 14 is raised in a longitudinal direction along tracks 18, disposed one at each side of the sluice valve 14, to clear the flow outlet 13. By the reverse operation, the flow outlet 13 is closed to stop the flow of liquid therethrough. Thus, the sluice valve 14 is first lowered in a longitudinal direction to a position in front of the flow outlet 13, and then the valve actuator 16 is lowered to rotate the cranks 17, thereby moving the valve member 15 laterally to seat it against the flow outlet 13.

Above the sluice valve 14 there is provided an operating mechanism 20, by which the sluice valve 14 is operated to open and close the flow outlet 13. The operating 3,330,536 Patented July 11, 1967 mechanism 20 comprises a tubular member 21, to the lower end of which there is secured a flange 22, and together forming a floor stand for the operating mechanism 20. The operating mechanism 20 stands upright on the floor 11 and is secured thereto by a plurality of bolts 23 which extend through the flange 22 and are anchored in the floor 11.

An operator or operating element 25 extends through the tubular member 21 of the floor stand and through the floor 11, downwardly to the sluice valve 14. The lower end of the operator 25 is formed with screw threads. A pair of

nuts

26, 26 are threadedly engaged with the lower threaded end of the operator 25 and secure the same to the valve member 15. The operator 25 is rotatable relatively to the valve member 15; however, its position is fixed in a longitudinal direction relatively to the valve member 15 by the

nuts

26, 26.

The lowermost end of the operator 25 is threadedly engaged with a nut 27, which is fixedly secured to the sluice valve actuator 16. By rotation of the operator 25, the valve actuator 16 is raised or lowered, which produces rotation of the several cranks 17, thereby unseating or seating the valve member 15, as previously described. The sluice valve 14, including the valve member 15 and the valve actuator 16, are raised or lowered in a longitudinal direction by longitudinal movement of the operator 25.

From the foregoing description, it is seen that the op erator 25 has two movements, one being a rotational movement for operating the valve actuator 16, and the other being a longitudinal movement for raising and lowering the sluice valve 14. The respective movements of the operator 25 are alternative, which is to say that the operator 25 remains longitudinally fixed when it is rotated, and the operator 25 is not rotated when it is moved in a longitudinal direction.

Referring now to FIGS. 2 and 3, a drive housing 30 is disposed at the top of the tubular member 21, of the floor stand. Within a lateral extension 31 of the drive housing 30, a shaft 32 is rotatably supported by suitable anti-friction bearings. A hand crank 33 is secured to the outer end of the shaft 32 for manually rotating the latter. The inner end of the shaft 32' is formed with a. bevel pinion 34.

Within the drive housing 30, there is a bevel gear 35 which is disposed on an upright axis that is coincident with the axis of the operator 25. The bevel gear 35 is secured to a sleeve 36 by a plurality of bolts 37. The upper end of the sleeve 36 is rotatably supported in the housing 30 by a bushing 38. The lower end of the sleeve 36 is rotatably supported by a plurality of ball bearings 39, which are disposed between a land 40 of the housing 30 and a flange 41 of the sleeve 36. The bevel pinion 34 is engaged with the gear 35, whereby the latter may be rotated by use of the hand crank 33.

A driving element 45 is disposed within the sleeve 36 and is fixedly secured thereto by several roll pins 46. The driving element 45 has a longitudinally extending bore, the upper portion of which is formed with screw threads for threaded engagement with the screw threads which are formed along the upper portion of the operator 25. The lower portion of the bore of the driving element 45 is of somewhat larger diameter than the operator 25, and therefore, is not engaged with the latter. At the lower end of the driving element 45 there are two notches 47 which are disposed at opposite sides of the driving element 45.

Below the driving element 45, there is a selector 50, which is a sleeve-like element having a longitudinal bore through which the operator 25 extends. The bore of the selector 50 is of somewhat larger diameter than the operator 25, so that there is no engagement between the selector bore and the operator 25. A keyway 51 extends along the operator 25. The selector 50 has a pair of

keys

52, 52, which are seated in the keyway 51. Each key 52 is fixedly secured to the selector 59 by a set screw 53. The keys 52 cause the selector 50 to be rotatably fixed, or nonrotatable, relatively to the operator 25. However, the keys 52 permit sliding movement of the selector 50 relatively to the operator 25.

At the upper end of the selector 50 there are a pair of

integral ears

54, 54, which are complementally formed with respect to the notches 47, to be engaged therewith by upward sliding movement of the selector 50 towards the driving element 45. The lower end of the selector 50 has a pair of

ears

55, 55 that are disposed at opposite diametral positions. Below the selector 50, there is a crossmem-ber 56 that is secured to the tubular member 21 of the floor stand. The cross-member 56 is formed with a pair of

notches

57, 57, as best seen in FIGS. 4 and 5. The

notches

57, 57 are complementally formed with respect to the

lower ears

55, 55 and are adapted to receive the latter when the selector is slidably moved downwardly towards the cross-member 56.

The selector 50 includes an annular groove 58. An eccentric 59 is disposed in the annular groove 58, in engagement with the selector 50. A shaft 60 extends outwardly from the eccentric 59. The shaft 60 is supported in a bushing 61 which is threaded into a laterally extending sleeve 62 and fixedly secured therein by a nut 63. A handle 64 is secured to the outer end of the eccentric shaft 60. By manipulation of the handle 64, the shaft 60 and the eccentric 59 are rotated, thereby raising or lowering the selector 50 by slidably moving it along the operator 25.

The tubular member 21 is formed with

stops

65, 66 which determine the two selective positions of the selector handle 64. In the first position of the selector handle 64, as seen in FIG. 4, it abuts the stop 65, and the selector 50 is in its uppermost position in which the

cars

54, 54 are interengaged with the

notches

47, 47 of the driving element 45. In the second position of the selector handle 64, it abuts the stop 66, and the selector 50 is in its lowered position, in which the

cars

55, 55 are engaged with the

notches

57, 57 of the cross-member 56.

In the operation of the operating mechanism 20, the selector handle 64 is moved to its first position, which raises the selector 50 into engagement with the driving element 45. Then the hand crank 33 is turned, thereby rotating the pinion 34 and the gear 35. The rotating movement is transmitted through the sleeve 36 to the driving element 45. By engagement of the driving element 45 with the selector 50 through the

interengaging notches

47, 47 and

ears

54, 54, the driving element 45 is norotatably secured to the operator 25, since the selector 50 is non-rotatable with respect to the operator 25. Thus, rotation of the driving element 45 produces rotation of the operator 25, which acts on the nut 27 of the valve actuator 16, to cause the latter to unseat the valve member 15 by lateral movement thereof, as has been previously described.

After the valve member 15 has been unseated, the selector handle 64 is moved to its second position, in which the selector 50 is lowered into engagement with the crossmember 56 by interengagement of the

cars

55, 55 and the

notches

57, 57. In this condition of the operating mechanism 20, the selector 50 is non-rotatable by reason of being secured to the cross-member 56, which is a fixed member. Since the operator 25 and selector 50 are nonrotatable relatively to each other, the operator 25 is nonrotatable in the second position of the selector 50. Then upon rotation of the driving element 45, the operator 25 will move longitudinally relatively to the driving element 45, thereby producing longitudinal movement of the sluice valve 14, to raise the latter, thereby to open the flow outlet 13.

Reverse operation of the selector 50 and the driving element 45 and the operator 25 causes the sluice valve 14 to be lowered longitudinally to the flow outlet 13, and the valve member 15 to be seated laterally against the flow outlet 13, 'for shutting off the flow therethrough. A collar 67 may be secured to the upper end of the operator 25, by means of a bolt 63, to limit the lowermost position of the operator 25.

The various elements of the operating mechanism 20 are suitably enclosed within the tubular member 21 and the housing 30, so as to be weather-tight, and thereby maintain the lubrication of the parts so that the mechanism may be easily operated at any time. When the sluice valve 14 is raised, the operator 25 projects upwardly above the top of the housing 30. The operator 25 may be provided with suitable markings, or other indicia, for indicating the position of the sluice valve 14. Thus, the sluice valve 14 may be partially raised or lowered to partially open or close the flow outlet 13. The operating mechanism 20 of this invention provides a simple mechanism by which there may be produced the several operating movements of the operator 25, which are required for opening and closing the sluice valve 14. If desired, the operating mechanism 20 may include a motor, or other power means may be provided for operating the same, particularly in such installations where the sluice valve 14 is of such large size and weight as to require a greater magnitude of force for raising and lowering the same, than can be applied manually.

Obviously those skilled in the art may make various changes in the details and arrangement of the parts without departing from the spirit and scope of the invention as defined by the claims hereto appended, and applicant therefore wishes not to be restricted to the precise construction herein disclosed.
