Description
Technical field
The utility model relates to a kind of anti-leakage valve, belongs to valve mechanism design field.
Background technique
Valve is industrial a kind of important fluid control devices, relates to national economy many departments, is the development fundamental equipments of national economy.At present, the application of valve is more and more extensive, and the bore of valve constantly increases, and pressure requirements also improves constantly.Valve leakage out of steam system refers to: medium is from valve internal leakage to valve.In the field that some are special, as: chemical plant, nuclear power station leak outside, and leak outside and can cause loss of material, befouling environment, also can cause the accident time serious.For inflammable and explosive, poisonous or have the medium of radiation, leak outside unallowable especially, thus valve must have reliable sealability.
The sealing surface place generally occurred between valve body and valve gap, between valve body and valve rod that leaks outside of valve, so the sealing configuration between design effectively valve body, valve gap, valve rod, is avoid valve leakage out of steam system problem in urgent need to solve.
Model utility content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of anti-leakage valve.
Technological scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of anti-leakage valve, comprise: valve body, valve gap, valve rod, flap, valve seat, cam rings, O shape circle, described bonnet lower inserts body top, described body wall offers the first groove, O shape circle groove, the valve gap sidewall of described first groove corresponding position offers inclined plane groove, the clamping of described cam rings beveled end enters in inclined plane groove, and the end clamping of described cam rings right angle enters in the first groove; O shape circle is provided with in described O shape circle groove.
Also comprise: filler, bellows, the sidewall of described valve gap valve rod insert division is provided with filler groove, in described filler groove, is provided with filler; Described stem lower portion is socketed with bellows, is provided with annular shirt rim bottom described bellows, and described annular shirt rim is socketed in bottom valve gap; Described valve rod is offered and is equipped with multiple O shape circle groove, in described O shape circle groove, be provided with O shape circle.
Also comprise screw, described cam rings end face is offered and is equipped with fixed groove, and described screw inserts cam rings from fixed groove and valve gap fixes.
