Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 2, a kind of three-way control valve of high pressure occasion, comprise valve body 1, guiding shroud 2, spool 3, valve rod 4, upper valve base 5, compensating cylinder 6, guide ring 7, sealing O type circle 8, piston 9, valve gap 10, filler 11, lower valve base 13, adapter 14 and actuator 12, valve body 1 is provided with runner mouth A, runner mouth B and runner mouth C.
Upper valve base 5 is installed in valve body 1, guiding shroud 2 spools 3 and valve rod 4 assemble in aggregates after upside-down mounting enter in valve body 1; Runner mouth C place is provided with adapter 14, and adapter 14 is provided with lower valve base 13, and adapter 14 and valve body 1 are connected firmly with fastening piece; Spool 3 and the valve rod 4 assembly stroke range between upper valve base 5 and lower valve base 13 is done to open and close action, can realize two-way fluid being merged into the function that fluid Huo Jiang mono-road, a road fluid is distributed into two-way fluid.
Be provided with compensating cylinder 6 in the top seam of valve body 1, compensating cylinder 6 inside is provided with up and down piston 9, is provided with guide ring 7 in the middle of piston 9, and guide ring 7 upper and lower sides is provided with sealing O type circle 8; Described valve rod 4 center is provided with a through hole to compensating cylinder 6 epicoele, the pressure of runner mouth C medium communicates with the pressure of compensating cylinder 6 epicoele, achieve pressure medium and act on equilibrium of forces on spool 3, make valve opening and close free and relaxed, stable action in running.
Valve body 1 is by Stud connection valve gap 10, and be provided with filler 11 between valve rod 4 and valve gap 10, valve gap 10 is connected with actuator 12.
When the three-way control valve of high pressure occasion works, final controlling element drives between the upper valve base of valve core valve stem in valve body and lower valve base and moves up and down, automatic control two-way fluid is merged into fluid Huo Jiang mono-road, a road fluid and is distributed into two-way fluid, be with the piston on ovable valve stem to move up and down in compensating cylinder simultaneously, eliminate the unbalanced force that medium produces on spool, greatly reduce the ouput force of actuator, piston arranges guide ring, arrange guiding to shroud play guide function in spool bottom, make valve operationally more steady, make a concrete analysis of as follows:
If runner mouth C is in closed condition, namely when spool 3 bottom and lower valve base 13 fit tightly, when medium flows to body cavity by runner mouth A, spool 3 top is subject to the downward pressure effect of medium, meanwhile, piston 9 is subject to the medium effect of upwarding pressure, and such two power balance mutually, during unlatching, the power of required actuator is very little; If runner mouth B is in closed condition, namely when spool 3 top and upper valve base 5 fit tightly, when medium flows to body cavity by runner mouth A, spool 3 bottom is subject to the medium effect of upwarding pressure, and meanwhile, medium flows in the cavity that is made up of compensating cylinder 6 and piston 9 through valve rod 4 inner equilibrium hole, piston 9 upper surface is subject to downward pressure effect, two power balance mutually, and during unlatching, the power of required actuator is very little; When spool 3 is in neutral position, medium flows into body cavity through runner mouth A, the effect of being under pressure of the upper and lower surface of spool 3, direction is contrary, and medium flows through upper valve base 5 valve seat mouth, enters valve body 1 epicoele, and have active force upwards to piston 9 lower surface, simultaneously medium flows in the cavity that is made up of compensating cylinder 6 and piston 9 through valve rod 4 internal balance hole, and piston 9 upper surface is subject to downward pressure effect, and such four power balance mutually; Therefore, the three-way control valve of high pressure occasion, in any state of work, remain at a kind of dynamic balance state, overcome the unbalanced force that spool produces, solve valve open and close difficulty when high pressure occasion, in running action not steadily, vibrate the problems such as large, meet the usage requirement under high pressure operating mode.
The present invention, by setting up the structural design of compensating cylinder 6, piston 9, sealing O type circle 8 and the valve rod 4 with equalizing orifice, eliminates the unbalanced force that medium produces on spool 3, greatly reduces the ouput force of actuator 12; Piston 9 is set up guide ring 7, set up guiding to shroud 2 play guide function in spool 3 bottom, make valve operationally more steady, solve valve opens and closes when high pressure occasion action in difficulty, running steady, vibrate the problems such as large, meet the usage requirement under high pressure operating mode.
