Description
Technical field
This utility model relates to controlling the Hydraulic Elements that fluid flows to, particularly to plug-in metal
Commutation seals hydraulic control one-way valve.
Background technology
Hydraulic control one-way valve passes through the control port pressure to spool, drives spool open valve port and close.
Now retrieve Publication No. CN105275484A hydraulic control one-way valve.Check valve in use controls
The control oil return line that push rod moves blocks up when having foreign body, and restricted due to flow in control oil return line, result in fluid will raise rapidly, top
Bar will quickly impact so that spool and the generation sharp impacts of swivel nut, it may occur that the hitting sound of ding-dong, sharp impacts acceleration valve
The breakage of core.
Utility model content
The purpose of this utility model is to provide the commutation of a kind of plug-in metal and seals hydraulic control one-way valve, effectively slow down spool with
The damaged in collision that swivel nut occurs.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of plug-in metal commutation seals hydraulic control one-way valve, including valve body, swivel nut, spool, valve seat, push rod be set in
The first spring on push rod, swivel nut inserts in valve pocket with valve body as threadeding, and spool is built in swivel nut, spool and swivel nut it
Between conflict and have the second spring, push rod through valve seat point to spool, the threaded screw-casing having the first spring of conflicting of swivel nut, spiral shell
Being arranged with hex slot in being easy to the first of screw-casing back-out, screw-casing rotates to realize being compressed axially or unclamping the second spring.
By using technique scheme, push rod is promoted by fluid, and push rod promotes spool to open along sliding valve seat；Push rod is not
During by the pressure of fluid, double from restoring force at the first spring and the second spring, push rod resets.Oil circuit oil pressure mistake when push rod
Gao Shi, the first spring is conflicted by screw-casing, is screwed by screw-casing, it is achieved compress the second spring so that spool is when opening valve port
The resistance being subject to increases, and slow down the impulsive force during collision of spool.And owing to screw-casing can screw out swivel nut, it is simple to the second spring
Quick-replaceable during infringement.
It is also preferred that the left screw-casing includes threaded walls and sliding wall, threaded walls is threadedly connected to swivel nut, and sliding wall slip is sealed in
Swivel nut.
By using technique scheme, threaded walls is used for fixing screw-casing, and sliding wall moves for screw-casing axis
Time sliding, seal prevent releasing of fluid.
It is also preferred that the left be provided with sealing ring between sliding wall and swivel nut.
By using technique scheme, sealing ring has good sealing property.
It is also preferred that the left screw-casing deviates from hex slot in one end of the second spring is provided with second.
By using technique scheme, in second, hex slot is easy to screwing of die nut, reaches quickly to screw spiral
Set realizes axial slip purpose.
It is also preferred that the left screw-casing is extended with circle set towards the second spring, one end of the second spring inserts in circle set.
By using technique scheme, the second spring being positioned by circle set, it is to avoid the shake of second spring and take off
From compression station.
It is also preferred that the left be provided with spiral cutting in circle set, the second spring is stuck in spiral cutting.
By using technique scheme, spiral cutting inserts in the gap location of the second spring, positions the second spring, it is to avoid the
Two springs depart from installs station；And when changing the second spring, due to the snap action of spiral cutting, can be directly by the second spring
Take out from valve inner.
It is also preferred that the left screw-casing contacts at spool, and the end of screw-casing conflict spool is provided with buffering ring.
By using technique scheme, the rigid collision of spool is become soft collision, improves spool by buffering ring
Impact environment so that spool is difficult to be broken.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
Embodiment 1: the commutation of plug-in metal seals hydraulic control one-way valve, as it is shown in figure 1, include valve body 1, swivel nut 11, valve
Core 13, valve seat 14, push rod the 15, first spring 16 and the second spring 12.Swivel nut 11 inserts in valve pocket at this end of valve body 1
With valve body 1 for threadeding.Hex slot 17 in offering first on the left of swivel nut 11, this groove is easy to die nut and is revolved by swivel nut 11
Go out.
Shown in Fig. 1, Fig. 2, Fig. 3, offering porose in first bottom hex slot 17, this hole is threaded columned spiral
Set 2, screw-casing 2 includes the sliding wall 23 of threaded walls 22 and smooth and round, and threaded walls 22 is provided with external screw thread and swivel nut 11 screw thread
Connect, between sliding wall 23 and screw-casing 2 matched in clearance both, be provided with the sealing ring 27 that rubber is made.Threaded walls 22 is towards valve
The outside of body 1, and sliding wall 23 is towards the inside of valve body 1.Screw-casing 2 points to the one end within valve body 1 and extends the circle of annular
Set 24, one end of the second spring 12 is inserted in circle set 24, in the other end insertion spool 13 of the second spring 12.
Push rod 15 sliding insertion is conflicted between valve seat 14, and push rod 15 and slide and is had the first spring 16, first spring 16 one end
It is enclosed within push rod 15, and push rod 15 is away from one end connection oil circuit control of spool 13.
Such as Fig. 1, during closed check valve, spool 13 and push rod 15 respectively under the first spring 16 with the effect of the second spring 12 to
The right side holds.
When check valve is opened, push rod 15, under oil pressure effect, overcomes the elastic force of the first spring 16 to be moved to the left, and withstands valve
Core 13, promotion spool 13 move to left, and reach valve and open.Utilize threaded walls 22 to rotate so that screw-casing 2 along sliding wall 23 to intrinsic pressure
Contract the second spring 12, it is achieved the second spring 12 compresses, and spool 13 moving process medium-rate slows down, and decreases clashing and breaking.
Embodiment 2: be with the difference of embodiment 1, as shown in Figure 4, the internal welding of circle set 24 is connected to the spiral shell of metal
Rotation cutting 25, the second spring 12 can be inserted in helical spring and realize fixing, and the end of circle set 24 be injection molded with circular and
The buffering ring 26 that rubber is made, it is achieved with the soft conflict of spool 13.
