Abstract
The utility model discloses an ejection rod control pluggable oil supplementary valve which comprises a valve body one-way valve seat, a thread one-way valve seat, a sealing washer, a check ring, an O-shaped rubber sealing ring, two one-way valve elements, two sets of springs and a spring seat. An internal hexagonal wrench screwing hole is formed in the end of one side of the thread one-way valve seat, and a connecting thread is arranged on the other side of the thread one-way valve seat. The valve body one-way valve seat and the thread one-way valve seat are connected through threads to form a pluggable valve body, a groove is formed in the valve body one-way valve seat, and the check ring and the O-shaped rubber sealing ring are arranged in the groove so that sealing between the valve body and a plugging valve hole can be achieved. The ejection rod control pluggable oil supplementary valve is simple in structure, small in size, and convenient to mount and adjust.
Description
Technical field
The utility model relates to a kind of hydrovalve, especially a kind of Fill valve.
Background technique
The Fill valve complex structure, the volume that on present stage market, circulate are large, Installation and Debugging inconvenience, and for the synchronizer repairing in hydraulic press twin-tub or multiple-cylinder synchronous hydraulic system, existing Fill valve obviously can not meet the demands.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of push rod control plug-in type
Fill valve, simple in structure, volume is little, is convenient to Installation and Debugging.
For realizing above-mentioned technical purpose, the utility model proposes a kind of push rod control plug-in type Fill valve, comprise valve body one-way valve seat, screw thread one-way valve seat, seal washer, back-up ring, O shape rubber seal, two inner elements of check valves, two groups of springs and spring seat, screw thread one-way valve seat one side end is provided with inner hexagon spanner and tightens hole, opposite side is provided with connecting thread, valve body one-way valve seat and screw thread one-way valve seat are threaded connection, form cartridge valve valve body, inner elements of check valve I is arranged in one-way valve seat, spring seat is arranged on the position by middle part in valve body, cluster spring I and cluster spring II are separately positioned on spring seat both sides, cluster spring I is connected with inner elements of check valve II with inner elements of check valve I respectively with cluster spring II, seal washer is arranged on screw thread one-way valve seat oil port, valve body one-way valve seat has groove, back-up ring and O shape rubber seal are arranged in groove, realize the sealing between valve body and plug-in type valve opening.
Described inner elements of check valve II is the inner elements of check valve with push rod, and push rod is arranged at valve port end.
Described inner elements of check valve I is the inner elements of check valve with push rod, and push rod is arranged at valve port end.
On the described inner elements of check valve cylndrical surface with push rod, six oil flow channels are set, are drilled with six oil flow channel holes at oil flow channel end, and on periphery, retained one section of full surface cylinder, this has just better ensured logical oil and the guiding of spool.
When Fill valve uses during at synchronizer, when the oil-feed of piston A side, piston B side is fuel-displaced, and now, inner elements of check valve I is in opening state, but inner elements of check valve II is in closed condition, and piston A side oil cannot reach B side by Fill valve; In the time that piston left lateral to Fill valve push rod knocks end cap, inner elements of check valve II is rushed open, and piston A side oil reaches piston B side by a-b-c-d-e-f-g passage, and piston A side oil starts the repairing of piston B side by Fill valve; The reason pistons such as while being rushed open due to the inertia of piston and piston rod and with the inner elements of check valve II of push rod, valve port unlatching is little, flow is little can continue left lateral, stop until bumping against end cap, now, valve port is all opened, piston A side oil by Fill valve to the repairing of piston B side, thereby reached the end repairing of twin-tub or the multi-cylinder of synchronizer control; When piston A side stops oil-feed, inner elements of check valve I is closed, and guarantees that the unlocking condition of inner elements of check valve I is to reach cracking pressure, i.e. pressure reduction between a and c.
A kind of push rod control plug-in type Fill valve the utility model proposes, simple in structure, volume is little, is convenient to Installation and Debugging.
