By adopting technique scheme, when dismantling, when opening valve gap when taking link apart, fastener just carries out spacing to the corresponding valve gap one end of connecting body, thus prevents valve rod to be blown because of medium high pressure effect in valve pocket, thus reduces potential safety hazard.
The present invention is arranged further: be provided with gap between described fastener and valve stem body, and the extending body of described valve gap is provided with the extending end being inserted into described gap.
By adopting technique scheme, during assembling, first valve rod being inserted, then fastener being snapped in groove, finally valve gap is loaded and valve gap and upper valve body are connected by link and just complete assembly manipulation, thus there is effect convenient for assembly.
The present invention is arranged further: described groove is arranged in the ring-type coaxial with described valve gap, and described fastener is at least provided with two, and described fastener is arranged in the arc-shaped coaxial with described valve gap.
By adopting technique scheme, while having effect convenient for assembly, what fastener can be stable plays position-limiting action to valve rod.
The present invention is arranged further: the width of described groove is greater than the thickness of described fastener.
By adopting technique scheme, fastener is made to there is certain mobile space at the axial direction of valve rod in groove, compacter when making to assemble, to improve stability.
The present invention is arranged further: described fastener is folded with thrust pad between valve gap one end corresponding to connecting body.
By adopting technique scheme, further increase stability.
Below in conjunction with accompanying drawing, the invention will be further described.
