Abstract
A kind of valve rod, that is, reassembling type safety valve, including hollow valve body, axially sliding is equipped with spool in valve body, and spool caudal action has a spring, and by spool compression fit valve body inlet；Spool tail portion is equipped with the hickey for external debugging bar.The utility model provides a kind of valve rod i.e. reassembling type safety valve, it is threaded interface at spool position, spool position adjusting is carried out by external debugging bar, tests the safe valve performance of valve rod, that is, reassembling type, on-line testing of the valve rod i.e. reassembling type safety valve in equipment is realized, debugging is more convenient.
Description
Technical field
The utility model belongs to valve technology field, refers in particular to a kind of valve rod i.e. reassembling type safety valve.
Background technology
Existing safety valve in equipment post debugging it is inconvenient, need again to remove it and carry out performance survey
Examination.
Utility model content
The purpose of this utility model is to provide a kind of valve rod i.e. reassembling type safety valve, and interface is threaded at spool position,
Spool position adjusting is carried out by external debugging bar, the safe valve performance of valve rod, that is, reassembling type is tested, realizes valve rod i.e. reassembling type
Safety valve is mounted on the on-line testing in equipment, and debugging is more convenient.
What the purpose of this utility model was realized in：A kind of valve rod, that is, reassembling type safety valve, including hollow valve body, valve
Axial sliding in vivo is equipped with spool, and spool caudal action has a spring, and by spool compression fit valve body inlet；Spool tail
Portion is equipped with the hickey for external debugging bar.
Preferably, the spool tail portion is equipped with mounting groove, and the body cavity tail portion is bolted with tailstock, and spring retainer is in tail
Between seat and mounting groove, the hickey is located at installation trench bottom, and the tailstock is equipped with the through-hole of opposite thread interface.
Preferably, the hickey extends downwardly, and gets through poppet head end face, passes through screw in poppet head end face
It is combined with plastic mattress, screw is threaded in across plastic mattress on hickey.
Preferably, the spool is rectangular, and four angles are the arc-shaped of fitting body cavity wall.
Preferably, the tailstock is circumferentially distributed through-flow notch.
Preferably, valve body tail portion outer wall thread is connected with nut connector.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
Need test when, by debug club head pass through tailstock through-hole and extend downwardly into spring bores, and with mounting groove bottom
The hickey in portion is spirally connected, then can be by pulling debugging bar, debugging bar to overcome the active force of spring thus by valve axially outward
Core is pulled outwardly, and opens the inlet of valve body.

Specific implementation mode
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-4：
A kind of valve rod, that is, reassembling type safety valve, including hollow valve body 3, axially sliding is equipped with spool 6, spool 6 in valve body 3
Caudal action has a spring 5, and by 6 compression fit of spool valve body 3 inlet 3a；6 tail portion of spool, which is equipped with, is used for external debugging
The hickey 6b of bar 1.
6 tail portion of spool is equipped with mounting groove 6a combined with Figure 1 and Figure 2, and 3 lumen caudal of the valve body is bolted with tailstock 4, spring 5
Between tailstock 4 and mounting groove 6a, the hickey 6b is located at the bottoms mounting groove 6a for limit, and the tailstock 4 is equipped with opposite
The through-hole 4a of hickey 6b.
Wherein, the hickey 6b is extended downwardly, and gets through 6 head end of spool, passes through spiral shell in 6 head end of spool
Nail 8 is combined with gasket 7, and screw 8 is threaded in across gasket 7 on hickey 6b.So set, hickey 6b two
End each serves as effect, more compact structure.
As shown in Fig. 2, the spool 6 is rectangular, and four angles are the arc-shaped of fitting 3 internal chamber wall of valve body.
As shown in figure 3, the tailstock 4 is circumferentially distributed through-flow notch.So set, facilitating the through-flow of liquid.
Specifically see that Fig. 1,3 tail portion outer wall thread of the valve body are connected with nut connector 2.2 endoporus of nut connector is less than valve body 3
Endoporus, can deviate to avoid tailstock 4.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
