Abstract
The utility model discloses a kind of valve rod anti-rotation structure of gas electromagnetic valve, the structure includes dust cap, handle ball, valve rod, anti-rotation cover, valve rod support base.The top outside of anti-rotation cover has external screw thread, and lower inside surface has internal thread.The axial centre of anti-rotation cover has an anti-rotation through hole being engaged with valve rod shaped face section, and the shape of anti-rotation through hole can be rectangle or other non-circular shapes such as oblate.Valve rod includes male end, the flat axle coordinated with anti-rotation cover and the circular shaft composition for going deep into valve rod support base of installation handle ball.User using during valve rod, valve rod deflect because its flat axle by by anti-rotation cover in the structure of anti-rotation through hole limit and can not be deflected, so can effectively avoid sealing gasket and valve body sealing surface generation sliding friction in gas electromagnetic valve.
Description
Technical field
It the utility model is related to the structure for preventing valve rod from rotating on a kind of gas electromagnetic valve.
Background technology
Gas electromagnetic valve is mainly used in that blast tube can be closed in gas leakage, after pending fault excludes, by manually opening
Blast tube, it is ensured that with gas safety, avoid that gas accidentses occur.The valve rod of gas electromagnetic valve is easy during being detected and used
Artificially rotated.Valve rod, which rotates, can drive sealing gasket to produce sliding friction with valve body sealing surface, so as to cause scratch to sealing gasket
Deng damage, sealing property is influenceed, brings potential safety hazard.
The content of the invention
The purpose of this utility model is in view of the shortcomings of the prior art, there is provided prevents valve rod from turning on a kind of gas electromagnetic valve
Dynamic structure, the structure can avoid the valve rod of magnetic valve from rotating, so as to avoid sealing gasket from producing slip with valve body sealing surface
Friction.
The technical solution of the utility model is：
A kind of valve rod anti-rotation structure of gas electromagnetic valve, including the support of valve rod, anti-rotation cover, dust cover, handle ball, valve rod
Seat.The bottom sides of described anti-rotation cover are designed with internal thread, and external screw thread is designed with top outside.Internal and external screw thread is used
It is connected in other fixed components with valve.Anti-rotation cover axial centre is provided with anti-rotation through hole.Contain flat axle in valve rod, can be with preventing
Turn the cooperation of cover anti-rotation through hole, so as to effectively prevent artificial rotation of the valve rod during being detected and used.
Brief description of the drawings
The utility model has drawings described below：
The valve rod anti-rotation structure figure of Fig. 1 gas electromagnetic valves；
Fig. 2 anti-rotation cover structure figures；
Fig. 3 is Fig. 2 top view；
Fig. 4 stem structure figures；
Fig. 5 is Fig. 4 A-A sectional views.
Embodiment
Below in conjunction with the accompanying drawings, detailed description is made to the utility model：
Valve rod as shown in Figure 4, valve rod 3 include the male end 9 of installation handle ball, the flat axle 10 coordinated with anti-rotation cover with
And go deep into the circular shaft 11 of valve rod support base and form.The cross sectional shape of wherein flat axle 10 is rectangle or oblate etc. other non-circular
Shape.The cross sectional shape of flat axle 10 shown in Fig. 5 is oblateness.
It is anti-rotation cover as shown in Figure 2, the top outside of anti-rotation cover 4 has male end 7, and lower inside surface has internal thread 8.
The axial centre of anti-rotation cover 4 has an anti-rotation through hole 6 being engaged with the flat axle of valve rod, the shape of anti-rotation through hole 6 can be rectangle or
Other non-circular shapes such as oblate, and its size and the matching size of the flat axle 10 of valve rod 3 close.Fig. 2 top views as shown in Figure 3 can be with
The shape for finding out anti-rotation through hole 6 is oblate.
As shown in figure 1, the valve rod anti-rotation structure of gas electromagnetic valve, including dust cap 1, handle ball 2, valve rod 3, anti-rotation cover 4,
Valve rod support base 5.Valve rod 3 passes through external thread section 9 through valve rod support base 5 and the anti-rotation through hole 6 of the axial centre of anti-rotation cover 4
It is connected with handle ball 2.Anti-rotation cover 4 is connected by the internal thread 8 of lower inside surface with valve rod support base 5, passes through top outside
There is external screw thread 7 to be connected with dust cover 1.After each part connection coordinates, the flat axle 10 of valve rod is just through the axial centre of anti-rotation cover 4
Anti-rotation through hole 6.User using during valve rod 3, because flat axle 10 in deflection by by anti-rotation cover 4 in anti-rotation through hole 6 knot
Structure limitation can not deflect.Sealing gasket in gas electromagnetic valve so can be effectively avoided to produce sliding friction with valve body sealing surface.
