Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that.
As shown in Figure 1, safety valve designed by the utility model, including bar 1, handle 2, safety valve housing 3, spool 4,
Seal sliding sleeve 5, rubber gasket 6, cutting ferrule 7, taper cutting ferrule 8, big spring 9, little spring 10, inner sleeve 11 etc..4 lower part of spool
Equipped with chamfer bevel, guarantee the tight fit between inner sleeve 11,4 top of spool is arranged with a groove, facilitates peace in groove
Taper cutting ferrule 8 is filled, 4 top of spool and bar 1 are in contact.
As shown in figs. 1 and 6, the angled orifices cooperated with spool 4 are provided among 11 lower part of inner sleeve, lower half portion nozzle connects
Socket part is arranged with pipe screw thread 13, facilitates installation, and side is provided with symmetrical four ventholes 12, and it is very high that top is provided with smooth degree
Circular hole can guarantee that valve core rod moves freely, and top is equipped with groove, facilitate installation little spring 10.
As shown in Figure 2-5, taper cutting ferrule 8 is two full symmetric half parts, in 4 groove of spool, outside taper cutting ferrule 8
Portion and the concentric cooperation of cutting ferrule 7；Little spring 10 is on valve core rod, and cutting ferrule 7 is withstood in one end, and the other end is mounted on inner sleeve 11
In, wherein the central diameter of little spring 10 is bigger than 8 diameter of taper cutting ferrule, but is less than 7 diameter of cutting ferrule；It is recessed that sealing sliding sleeve 5 is provided with annular
Slot facilitates installation rubber gasket 6, and sealing sliding sleeve 5 can be provided with cylindrical hole in 3 inner wall easy slide of safety valve housing, centre,
Guarantee between spool 4 and sealing sliding sleeve 5 to be interference fit.It is lower equipped with big spring 9 to seal sliding sleeve 5, the path of big spring 9 is greater than
7 outer diameter of cutting ferrule, the outer diameter of big spring 9 are less than 11 outer diameter of annular groove and inner sleeve of sealing 5 lower half portion of sliding sleeve；It is set on bar 1
There is external screw thread, top is provided with through-hole, and handle 2 is facilitated to install；Safety valve housing 3 is equipped with can flexibly revolve between internal screw thread and bar 1
Dynamic, safety valve housing 3 is equipped with symmetrical four through-holes, convenient and fixing piece installation.
When specifically used:
Viewed from above clockwise when turning handle 2, relative motion occurs for bar 1 and safety valve housing 3, and bar 1 is comparatively safe
