On main valve body；And for isolate the inner cavity of hydraulic cylinder and main valve body with prevent mud enter hydraulic cylinder every mud pan,
It is installed between the cylinder body of hydraulic cylinder and main valve body.
Valve head is mounted on the piston of hydraulic cylinder in above-mentioned patent, is used to implement by Driven by Hydraulic Cylinder valve head to valve body
Interior fluid media (medium) shuts off；And cutting for fluid medium can only be used to implement in above-mentioned patent by way of Driven by Hydraulic Cylinder
Stream, it is impossible to automatic-diversion closure be realized to the in vivo fluid media (medium) of valve, so as to influence the practicality of the check-valves in actual use
Property.
Utility model content
The purpose of this utility model is to provide a kind of check-valves of dual regulation, which realizes certainly
It is dynamic while shut off, moreover it is possible to shutting off for fluid medium to be used to implement by actuator, so as to improve the practicality of the check-valves
Property.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of dual regulation is stopped
Valve is returned, including valve body, valve deck, the valve rod being arranged on valve deck and is arranged on the in vivo runner of valve, is equipped with above the valve deck
The actuator of reciprocating movement is in axial direction realized for driving stem, seal is provided on the runner and the seal will
Runner is divided into two parts of influent stream chamber and outflow lumen, and the valve rod is equipped with to seal the spool of seal, on the spool
Equipped with being sheathed on valve rod and enabling the axial cavity of realizing sliding of the spool along valve rod, the side wall of the cavity is convex equipped with first
Ring, the lateral wall of the valve rod, which is equipped with, to be coordinated with the first bulge loop for limiting the second bulge loop departed between valve rod and spool,
It is formed between the valve rod end face and cavity and realizes the gap moved along the axial of valve rod for spool.
By using above-mentioned technical proposal, the gap formed between spool and valve rod so that spool can be realized on valve rod
Sliding, and by competing mode between the first bulge loop and the second bulge loop, it is used to implement the /V to spool so that valve rod
Movement can be realized with movable valve plug and will not be realized between spool and is separated, for realizing the adjusting to spool.When under valve rod
When the distance between end and seal are less than the width in gap, spool can seal seal under the active force of gravity, so as to real
The automatic-diversion closure of existing fluid medium improves the practicability of the check-valves.When to realize preferable sealing to seal, lead to
Part of overdriving applies active force to spool towards seal direction so that and spool can be contradicted preferably on seal, so that
Better seal can be realized by obtaining check-valves.
It is further arranged to：Bolster is equipped between the valve rod end face and cavity.
By using above-mentioned technical proposal, the in vivo fluid media (medium) of valve applies impact forces to spool towards valve rod direction
When, the impact force that spool applies valve rod can be reduced by the setting of bolster, so as to extend the service life of spool and valve rod.
It is further arranged to：The card slot being embedded for bolster is equipped in the cavity, the bolster protrudes from the card
Slot.
By using above-mentioned technical proposal, actuator band ovable valve stem and spool towards seal direction move when, spool supports
It touches on seal, actuator continues to apply active force to valve rod at this time；It can be retracted by the setting bolster of card slot
Inside card slot, actuator is made not cause excessive deformation to bolster during force, made so as to play protection to buffering
With.And the bolster for protruding from card slot can play the role of buffering to the impact force that spool applies towards valve rod.
It is further arranged to：The setting that is recessed inwardly on one side of the spool towards valve deck forms a recessed portion.
By using above-mentioned technical proposal, the setting of recessed portion enables spool fluid medium to play preferably carrying work
With thus with movable valve plug better seal on seal.
It is further arranged to：One end of the seal towards spool expands outwardly to form an expansion mouth, the expansion mouth
The first outwardly sealing ring is inside embedded with, the spool contacts at expansion mouth and is adapted to therewith.
By using above-mentioned technical proposal, the more preferable cooperation between spool and seal is realized by the setting of expansion mouth,
And the setting for passing through the first sealing ring increases the leakproofness between spool and seal.
It is further arranged to：The outer surface of first sealing ring is outwardly arcwall face.
By using above-mentioned technical proposal, the setting of arcwall face causes fluid media (medium) when by seal, to reduce first
Depositing for sealing ring and caused by the fluid media (medium) in flowing resistance, so as to reduce the probability that check-valves resonates.
It is further arranged to：The one side of the valve deck towards valve body is equipped with outwardly sealing bulge loop, the valve body pair
It should be in the position of sealing bulge loop equipped with the closure gasket groove being embedded for sealing bulge loop.
By using above-mentioned technical proposal, the cooperation sealed between bulge loop and closure gasket groove is increased between valve deck and valve body
Contact area so that better seal effect can be reached between valve deck and valve body.
It is further arranged to：The second sealing ring is equipped between the valve deck and valve body.
By using above-mentioned technical proposal, the setting of the second sealing ring increases the leakproofness between valve deck and valve body.
In conclusion the utility model has the advantages that：It is used for by the gap formed between spool and valve rod
It realizes the dual regulation of the check-valves, promotes the practicability of the check-valves；The setting of bolster reduce between spool and valve rod by
The impact forces arrived, and under the action of sealing bulge loop, closure gasket groove and the second sealing ring, add the sealing of check-valves
Property.
