As a preferred solution of the present invention, the inwall processing of the fluid cylinder has annular slot, and in the annular slot
Heart line is overlapped with the lumen centers line of the fluid cylinder.
Using the design of such fixed device, solves in the prior art because the rotation of spring twists, be easy to happen and column
The problem of plug bumps against, second snap-gauge is increased, the rotation of spring is effectively prevented, improves valve fatigue service life,
Using more safe and reliable.
As a preferred solution of the present invention, the first snap-gauge end is provided with boss, the boss and the annular
Card slot is flexibly connected.
As a preferred solution of the present invention, second snap-gauge is flexibly connected with the plug.
As a preferred solution of the present invention, second snap-gauge includes stationary plane, and the stationary plane and the plug are living
Dynamic connection.
As a preferred solution of the present invention, the stationary plane and the plug apical grafting.
As a preferred solution of the present invention, second snap-gauge includes cambered surface, and the cambered surface and the stationary plane are mutual
Vertically, it is designed as preventing from interfering with plunger using such, the cambered surface can adjust radian according to design requirement.
As a preferred solution of the present invention, first snap-gauge is arranged symmetrically, the chamber of second snap-gauge and the fluid cylinder
Internal wall keeps vertical.
Compared with prior art, beneficial effects of the present invention:
The configuration of the present invention is simple, size are small, easy for assemble or unload, and use reliability is high, increases anti-rotation device, solve existing
Have in technology because the rotation of spring twists, is easy to happen the problem of bumping against with plunger, improves valve fatigue service life, improve
The functional reliability of valve.

Specific embodiment
Below with reference to embodiment and specific embodiment, the present invention is described in further detail, but should not understand this
It is only limitted to embodiment below for the range of aforementioned body of the present invention, it is all that this is belonged to based on the technology that the content of present invention is realized
The range of invention.
As shown in figure 1, figure 2, figure 3, figure 4 and figure 5, the present embodiment valve includes: fixed device 1, plug 2, spring 3, fluid cylinder
4, valve body and valve seat 5, pressure cap 7, valve body and valve seat 5 are fixedly mounted on fluid cylinder 4, and spring 3 is movably arranged on valve body and valve seat 5, fixed
Device 1 is movably arranged on spring 3, and pressure cap 7 is fixedly mounted on fluid cylinder 4, plug 2 and 7 apical grafting of pressure cap.
As shown in figure 3, fixed device 1 includes: the first snap-gauge 12, the second snap-gauge 13, rotation center hold 11, the first snap-gauge 12
It is 2.First snap-gauge 12 is arranged symmetrically, and the second snap-gauge is vertical with the holding of oil cylinder cavity inner wall, and the second snap-gauge 13 includes stationary plane
131.To prevent from interfering with plunger 8, the second snap-gauge 13 further includes cambered surface 132, and cambered surface 132 is mutually perpendicular to stationary plane 131, and first
12 end of snap-gauge includes boss 121, is flexibly connected with annular slot 6, and boss 121 and annular slot 6 cooperate.
As shown in Figure 1 and Figure 2, the inwall processing of 4 cavity of fluid cylinder has annular slot, and the center line and fluid cylinder of annular slot
