Abstract
The utility model relates to a gas charging and discharging valve for external counterpulsation medical devices. The gas charging and discharging valve for external counterpulsation medical devices is characterized in that the upper and the lower parts of the cavity of a piston valve are respectively provided with waist-shaped gas outlet holes and gas inlet holes at the peripheries, and the middle part of the cavity of the piston valve is provided with four symmetrical gas charging holes; the upward and downward movement of a piston in the cavity is controlled by a magnetic, i.e. when the magnet of the electromagnetic valve moves in a vertical direction, a pressure container supplies gas in a horizontal direction; in the process of gas charging to gas discharging and in the process of gas discharging to gas charging, the gas charging holes and the gas outlet holes are not directly switched on. Therefore, the gas charging and discharging valve of the utility model has the advantages of large working flow, small electromagnetic acting force, high working frequency, low power consumption, low noise and good tightness, and can be used for quick closing valves in pneumatic systems.
Description
A kind of valve that is used for the ECP special use, the valve type of genus engineering element or parts.
Be used for medical treatment at present and go up the air valve of ECP, generally be adopt two independently air valve take turns to operate, complex structure, noise is big, poor sealing performance.
The purpose of this utility model provides the ECP special valve that a kind of inflation and exhaust are connected as a single entity.
Scheme of the present utility model is cavity valve body seat of design, a piston is installed in this cavity, spring of lower part of piston pad, piston is fixedlyed connected with a major axis, and the top of major axis contacts with an electromagnet, when electromagnet moves downwards, major axis top pressurized on the piston also drives piston motion downwards in the cavity of valve block, after electromagnet resetted, the spring of piston bottom moved upward piston, reached with a valve body to inflate and the exhaust purpose; The critical component of this scheme is that the top of cylindric valve block has 4 exhaust ports all around, have 4 inlet holes around the bottom, middle of piston has the waist connected in star, inlet hole is connected with the container with pressure gas source, around the valve block middle part, 4 inflation interfaces are housed, this inflation interface and the rubber balloon connection (rubber balloon is bundled in the relevant position of human body) that is used for carrying out ECP, when piston moves down, pressure gas source is inflated rubber balloon with the inflation interface by 4 inlet holes of valve block bottom, rubber balloon is expanded, press to certain position of human body, when moving on the piston, pressure gas source in the air bag is by the outside exhaust of exhaust port on valve block top, fill exhaust so repeatedly, act on human body, reach the ECP purpose with rubber balloon.
The utility model has the advantages that gas pressure direction and solenoid valve active force in the pressurized container are orthogonal, so reduced the electromagnetic force of one control air valve motion greatly, make the air valve frequency of okperation improve, noise is low, in addition, from being inflated to exhaust or from be vented to gas replenishment process, do not have between inflation inlet and the relief opening and directly connect (short circuit) phenomenon, improved sealability greatly, save gas, it is medical that the utility model is specially adapted to ECP, also is suitable for the quick-closing valve in the pneumatic system.
Accompanying drawing of the present utility model has;
Accompanying drawing 1 is an erection drawing.
Accompanying drawing 2 is structural drawing of valve block 3.
Accompanying drawing 3 is structural drawing of piston 2.
Accompanying drawing 4 is structural drawing of major axis 1.
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing:
Accompanying drawing 1 is an erection drawing of the present utility model, by valve block 3, piston 2 and electromagnet 17 are formed, fixedly connected with electromagnet 17 with screw 16 in the top of valve block 3, valve block 3 is cavity body cylindraceous, as shown in Figure 2, have 4 waist shape inlet holes 6 and exhaust port 7 around the bottom of cavity and the top symmetrically, inlet hole 6 is connected with the gas source vessel with pressure, have 4 air-filled pores 5 symmetrically around its middle part, air-filled pore 5 has internal thread, so that be connected with inflation interface 4, and with seal ring 15 sealing, inflation interface 4 is connected respectively to the bottom of rubber balloon (not shown) valve block 3 cavitys to be inflated and makes trapezoidal, in this cavity, adorn a piston 2, between piston 2 dividing plates 20 and valve block 3 cavity bottoms, be lined with spring 13, piston 2 is hollow cylinders, as shown in Figure 3, its inside has a dividing plate 20 and cylindrical body to be connected as a single entity, dividing plate 20 has the center hole 21 with screw thread, and there is aperture 22 on the next door in hole 21, and the cylindrical of two up and down of piston 2 studs with teflon piston edge circle 19, make piston 2 stage casings form a waist connected in star 18, the cavity internal diameter of the external diameter of piston ring carrier 19 and valve block 3 is slidingly matched; Accompanying drawing 4 is schematic representation of major axis 1, and screw thread is arranged at the bottom of axle, and there is plate washer 23 at the middle part, and the screw thread of axle 1 bottom is with piston 2 dividing plates 20 center holes 21 are spirally connected and fix with nut 8; Electromagnet 17 among Fig. 1 is schematic representation, electromagnet 17 is made up of coil and electromagnet block, electromagnet contacts with major axis 1 top on the piston 2, columniform valve block 3 bottoms are inserted a gas source vessel interior (not shown gas source vessel) with pressure and are also fixed with this seal of vessel with rubber sealing ring 11 and screw 12,4 inlet holes 6 and gas source vessel are connected, in order to reduce the vibrating noise of piston 2 upper and lower motion in valve block 3 cavitys, bottom and top at cavity all are lined with rubber seal 9 and 14; Working procedure of the present utility model is: after electromagnet 17 energisings, electromagnet block is pressed to the top of major axis 1, major axis 1 pressurized, driving piston 2 moves to the cavity bottom, when piston is displaced downwardly to cavity bottom, inlet hole 6 is connected with the waist connected in star 18 of piston 2, and the exhaust port 7 on top is blocked by the upper end of piston edge circle, and the pressed gas that is come by the pressure gas source container is through inlet hole 6, waist connected in star 18, the rubber balloons inflation that 5 pairs of air-filled pores are external, when electromagnet resets, the elastic force of spring 13 moves upward piston 2, baffle plate 23 on the major axis 1 is limited the position by rubber seal 14, this moment, waist connected in star 18 was connected with exhaust port 17, and the gas in the rubber balloon is through exhaust port 17 outside exhausts, simultaneously, inlet hole 6 is blocked by the lower end Xiang Quan of piston 2, aperture 22 on piston 2 dividing plates 20 is as losing heart the gas pressure when the minimizing piston presses down.
