Valve and valve body of releasing, are equipped with bleeder valve and control cylinder assembly in the side of the intake valve, valve are equipped with the intake valve
Bar and valve plate, are equipped with the valve body of releasing and release valve deck, release that the 3rd is equipped between valve deck and valve body of releasing is close described
Seal, spool of releasing is equipped with the bleeder valve body, control cylinder assembly is connected with the side of the valve body of releasing, described
One end of piston shaft in control cylinder assembly is located at bleeder valve in-core, gear segment is equipped with the piston shaft, in the valve
One end of bar is cased with gear, and the gear is meshed with the gear segment of piston shaft.
Further improvement of the present invention is：The control cylinder assembly includes cylinder body, piston and piston shaft, described
Piston is equipped with cylinder body, piston shaft has been bolted on the piston, resetting spring is cased with the piston shaft.
When oil cylinder has pressure input, oil pressure promotes piston, and piston shaft stretches out band moving gear and opens intake valve, while promotes bleeder valve valve
Core acts, and closes bleeder valve；When oil cylinder cuts off input pressure, resetting spring promotes piston reset, and piston shaft is retracted with moving teeth
Wheel closes intake valve, while pulls spool action of releasing, and opens bleeder valve.
Further improvement of the present invention is：Multiple first sealing rings and support are equipped between the piston and cylinder body
Ring.
Further improvement of the present invention is：Baffle ring and multiple second close is equipped between the piston shaft and spool of releasing
Seal.
Further improvement of the present invention is：Mutually it is fixedly connected by multiple holding screws between the valve plate and valve rod.
The present invention have the advantage that compared with prior art for：
Compact-sized, robust performance, using no oil machine gear lubricating oil pump drive control oil cylinder, and then drives valve plate and bleeder valve
Action；It is driven between control cylinder and valve plate by gear, high transmission accuracy, long working life；Control cylinder assembly with
Bleeder valve shares piston shaft, and bleeder valve action control precision is high, and action is fast；Valve plate uses the preassembled fixed knot of holding screw
Structure, eliminates and damages the hidden danger of head since holding screw loosens；The parts such as highly integrated control cylinder, bleeder valve, knot
Structure is compact, small.
