The technological scheme that technical problem adopted that the utility model solves is: Stroke Control gearbox control valve, comprise valve body, valve body is provided with a suction port and two air outlets, it is characterized in that: have the left and right inner chamber that two symmetries connect on the valve body, suction port is located at the upper end of valve body, two air outlets are located at the and arranged on left and right sides of valve body respectively, communicate with left and right inner chamber middle part respectively; The inner chamber of valve body is provided with valve base, guide sleeve, is provided with spool in the valve base, and spool comprises that an end of valve rod, valve rod is provided with sealing plate, be provided with vent in valve rod and the sealing plate, the cylinder of valve rod is provided with seal groove, and seal groove is provided with O-ring seals, and sealing contacts O-ring seals with valve base; Inner chamber bottom at valve body is provided with step, card has the controlling rod of split washer to run through guide sleeve, one end stretches out valve body, split washer withstands on the step of body cavity bottom, be provided with Returnning spring between split washer and guide sleeve, be provided with seal groove in the guide sleeve, seal groove is provided with seal ring, and the cylinder sealing of seal ring and controlling rod contacts.
During use, when suction port connects air pressure, and controlling rod do not have active force, and Pneumatic pipe cleaner is crossed the vent of spool, enters the middle part of body cavity, and is divided into two-way, from left and right air outlet output pressure; Right controlling rod is under the effect of gearbox operation push rod, and push lever moves up, and the valve port of controlling rod and the sealing plate vent of spool are closed at this moment, thereby have cut off the suction port gas circuit of the output pressure of air outlet to the right; Push rod fails down, and controlling rod is under the effect of Returnning spring, and gas circuit is closed, and gets back to original state.Left side gas circuit principle is identical with right gas circuit principle.
During concrete the use, also be provided with valve core spring in the valve base, valve core spring withstands on an end of valve rod, and the middle part of the inner chamber of valve body is provided with middle cover, is provided with step between middle cover and valve base, and the sealing plate outer ring withstands on the step between middle cover and valve base.
During concrete the use, be provided with relief opening between the left and right inner chamber of valve body, the top and the valve base inner chamber that are provided with step between relief opening and middle cover and valve base communicate.
Working principle: during use, when suction port connects air pressure, and controlling rod does not have active force, Pneumatic pipe cleaner is crossed the vent of spool, enters the middle part of body cavity, and is divided into two-way, from left and right air outlet output pressure, simultaneously, because the sealing plate outer ring withstands on the step between middle cover and valve base, left and right air outlet and relief opening are obstructed; Right controlling rod is under the effect of gearbox operation push rod, push lever moves up, the valve core spring compression, the sealing plate outer ring breaks away from the step between middle cover and valve base, the valve port of controlling rod and the sealing plate vent of spool are closed at this moment, thereby have cut off the suction port gas circuit of the output pressure of air outlet to the right; Push rod fails down, and gas circuit is closed, and simultaneously, the residual air of right air outlet is discharged to relief opening, valve core spring reduction, and the sealing plate outer ring withstands on the step between middle cover and valve base, and controlling rod is got back to original state under the effect of Returnning spring.Left side gas circuit principle is identical with right gas circuit principle.
The utility model has changed the ring wear problem that has eight vents and O-ring seals frequently to contact on the original plunger, has improved sealability, has reduced hidden danger such as gas leakage, gas blowby, has improved working life.
The beneficial effects of the utility model are: the utility model working principle science, processing technology are simple, commutation flexibly, seal ring is not easy wearing and tearing, compact structure, operation is lightly convenient, practical, can be used as the control valve in the various atmospheric controls.
