Mouthful, the valve shell upper inside wall is provided with thread groove, and the valve body inner bottom part is provided with steel ball, in steel ball size and valve shell
Footpath is identical, and the steel ball top is provided with plunger, and the plunger upper part is provided with spring, and the spring top is provided with adjustment screw, institute
The diameter matches of adjustment screw and valve shell upper inside wall thread groove are stated, at the top of the adjustment screw, hexagonal stud is provided with
Hole.
Preferably, the adjustment screw top is additionally provided with rotation stop partition, and the rotation stop partition top is sealed using plug
It is stifled, external screw thread, the plug external screw thread and valve shell screw-internal thread fit is provided with outside the plug, is provided with the top of the plug
Hexagonal column bolt hole.
Preferably, the plunger bottom is provided with concave spherical surface structure.
Preferably, groove is provided with the middle part of the plunger, be cased with O-ring seals on the groove.
Preferably, the valve shell upper inside wall and outer wall are equipped with screw thread.
Preferably, radius of height of the top of the unloading port away from valve shell inner bottom part less than steel ball.
Compared with prior art, the beneficial effects of the utility model are：By the plug that press-fits of one-way pressure-limit valve is changed
For bolt plug, flexible can be carried out to the pressurized size for unloading load forces of pressure limiting valve, you can in allowed limits to pressure limiting
The pressure of valve is arbitrarily adjusted, so that it is guaranteed that the payment qualification rate of product reaches 100%, improve production efficiency, and and reduce production
Cost；Secondly one-way pressure-limit valve valve body structure described in the utility model is simple, easy to manufacture, easy to maintenance, long service life.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage seem to become apparent from understanding, below in conjunction with accompanying drawing and
Specific embodiment, is described in further detail to this utility model.It should be appreciated that described embodiment herein is only
It is in order to explain this utility model, rather than for limiting protection domain of the present utility model.
A kind of automobile hydraulic power steering gear one-way pressure-limit valve assembly, bag valve shell, the valve shell bottom set
There is oil-in, the valve shell bottom sidewall is provided with unloading port, and the valve shell upper inside wall is provided with thread groove, the valve
Bottom is provided with steel ball in vivo, and steel ball size is identical with valve shell internal diameter, and the steel ball top is provided with plunger, the plunger upper part
Spring is provided with, the spring top is provided with the diameter of adjustment screw, the adjustment screw and valve shell upper inside wall thread groove
Matching, is provided with hexagonal column bolt hole at the top of the adjustment screw.
The adjustment screw top is additionally provided with rotation stop partition, and the rotation stop partition top is blocked using plug, described
External screw thread, the plug external screw thread and valve shell screw-internal thread fit is provided with outside plug, is provided with hexagon prism at the top of the plug
Shape bolt hole.
In order that carrying out good cooperation between plunger and steel ball, the plunger bottom is provided with concave spherical surface structure.
Groove is provided with the middle part of the plunger, O-ring seals is cased with the groove, and setting up O-ring further can increase
The sealing property of plunger.
The valve shell upper inside wall and outer wall are equipped with screw thread.
Radius of height of the top of the unloading port away from valve shell inner bottom part less than steel ball, it is ensured that unloading port's top quilt
Steel ball is blocked.
This utility model principle is：When the downward tension force that input pressure is produced more than valve body inner spring, in oil-in
Steel ball is pushed up by oil pressure upwards, and steel ball then drives plunger upwardly spring, oil-in is connected with unloading port, oil plant Jing oil-ins
Flow to unloading port.
When oil pressure is less than tension force of spring, now steel ball is bottomed out, and oil-in is blocked by steel ball, oil-in and unloading port every
Disconnected, oil plant cannot be introduced into valve body.
When in use, its purpose seeks to control the flow velocity that oil plant Jing oil-ins flow into oil-out this utility model, therefore
Under the powerful tension force effect of spring, pressure limiting valve can preferable control pressure.
This utility model by pressure limiting valve be designed as by adjustment screw and plug collaboration blocked, can by rotate adjust
Save screw to adjust the size of spring tension, the length that set screw stretches into valve shell is more, and spring tension is bigger, steel ball energy
The pressure for bearing is bigger；Plug stretches into that valve shell length is fewer, and spring tension is less, and the pressure that steel ball can bear is less, because
This design can production out after which is debugged in limited scope, it is ensured that yield rate is up to 100%.
The diameter of steel ball is identical with the internal diameter of valve shell, therefore steel ball can also play sealing function on the inside of valve body, subtract
Little oil plant penetrates into steel ball top, and the effect of O-ring and plunger is, in order to further enhance sealing property, to prevent oil plant from oozing
Enter to spring place position, once oil plant enters into spring place position and is filled with completely, then pressure limiting valve will fail, because
The compression ratio of liquid is far smaller than air.
The above specific embodiment of the present utility model, does not constitute the restriction to this utility model protection domain,
Any various other corresponding change and deformation according to done by technology design of the present utility model, should be included in practical
In new scope of the claims.
