Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1～2, a kind of three-way control valve of high pressure occasion, including valve body 1, guiding and shroud 2, spool 3, valve rod 4, upper valve base 5, compensating cylinder 6, guide ring 7, sealing O 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.
Being provided with upper valve base 5 in valve body 1, guiding shrouds 2 spools 3 and valve rod 4 assembles integral upside-down mounting afterwards and enters in valve body 1；Being provided with adapter 14 at runner mouth C, adapter 14 is provided with lower valve base 13, adapter 14 and valve body 1 and is connected firmly with securing member；Spool 3 and valve rod 4 assembly stroke range between upper valve base 5 and lower valve base 13 make opening and closing action, can realize that two-way fluid is merged into fluid Huo Jiang mono-road, a road fluid and be distributed into the function of two-way fluid.
Being provided with compensating cylinder 6 in the top seam of valve body 1, internal being provided with in the middle of up and down piston 9, piston 9 of compensating cylinder 6 is provided with guide ring 7, and guide ring 7 upper and lower sides is provided with sealing O 8；Described valve rod 4 center is provided with a through hole and communicates with the pressure of compensating cylinder 6 epicoele to compensating cylinder 6 epicoele, the pressure of runner mouth C medium, it is achieved that pressure medium acts on the balance of power on spool 3 so that valve opening and closedown are free and relaxed, stable action in running.
Valve body 1, by Stud connection valve gap 10, is 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, executor drives valve core valve stem upper valve base in valve body and moves up and down between lower valve base, automatically control two-way fluid to be merged into fluid Huo Jiang mono-road, a road fluid and be distributed into two-way fluid, piston on band ovable valve stem moves up and down in compensating cylinder simultaneously, eliminate the out-of-balance force that medium produces on spool, it is substantially reduced the power output of actuator, piston arranges guide ring, arrange guiding to shroud play guide function in spool bottom, make valve the most steady, make a concrete analysis of as follows:
If at runner mouth C in off position, when i.e. spool 3 bottom and lower valve base 13 fit tightly, when medium is flow to body cavity by runner mouth A, spool 3 top is by the downward pressure effect of medium, meanwhile, piston 9 is mutually balanced by the medium effect of upwarding pressure, two such power, during unlatching, the power of required actuator is the least；If at runner mouth B in off position, when i.e. spool 3 top and upper valve base 5 fit tightly, when medium is flow to body cavity by runner mouth A, spool 3 bottom is by the medium effect of upwarding pressure, and meanwhile, medium is in valve rod 4 inner equilibrium hole flows into the cavity being made up of compensating cylinder 6 and piston 9, piston 9 upper surface is by downward pressure effect, two power mutually balance, and during unlatching, the power of required actuator is the least；When spool 3 is in centre 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, in opposite direction, medium flows through upper valve base 5 valve seat mouth, enters valve body 1 epicoele, and piston 9 lower surface is had active force upwards, medium is in valve rod 4 internal balance hole flows into the cavity being made up of compensating cylinder 6 and piston 9 simultaneously, and piston 9 upper surface is mutually balanced by downward pressure effect, such four power；Therefore, the three-way control valve of high pressure occasion, any state in work, remain at a kind of dynamic balance state, overcome the out-of-balance force produced on spool, solve valve and open and close the problems such as action in difficulty, running is unstable, vibration is big when high pressure occasion, meet the use requirement under high pressure operating mode.
The present invention, by setting up compensating cylinder 6, piston 9, sealing O 8 and the structure design of the valve rod 4 with balance pipe, eliminates the out-of-balance force that medium produces on spool 3, is substantially reduced the power output 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 the most steady, solve valve and open and close the problems such as action in difficulty, running is unstable, vibration is big when high pressure occasion, meet the use requirement under high pressure operating mode.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
