Abstract
The utility model provides an anti-leakage goggle valve, which can significantly resolve the problems such as that the corrugated pipe is easy to break caused by frequently switching the valve. The anti-leakage goggle valve comprises a left valve body, a middle valve body, a right valve body, a valve plate, a valve plate sealing element, a locking lead screw and a locking nut, wherein the middle valve is provided between the left and right valve bodies, the valve plate is provided between the middle valve body and the left valve body and is sealed by the valve plate sealing element, the upper ends of the three valve bodies are connected integrally via the locking lead screw and the locking nut, the valve sealing element is connected between the middle valve body and the right valve body, which comprises two rubber sealing rings embedded in a slot between the middle valve body and the right valve body.
Description
Technical field
The utility model relates to a kind of valve that pipeline gas opens and closes that is used for, and relates in particular to a kind of blank-plate valve of anti-leak.
Background technique
The blank-plate valve of prior art comprises left valve barrel, middle valve body, right valve barrel, valve plate, valve plate Sealing, locking screw mandrel and locking nut, middle valve body places between left valve barrel and the right valve barrel, valve plate places between valve body and the left valve barrel, in be connected with metal bellows between valve body and the right valve barrel, the bit shift compensation so that valve opening and closing to be provided.But owing to the frequent keying of valve causes bellows bursts to produce the leakage of poisonous or inflammable gas easily, thereby have to change bellows, cause the transportation of pipeline gas normally not carry out, therefore be necessary this structure is improved.
Summary of the invention
The purpose of this utility model provides a kind of blank-plate valve of anti-leak, and this blank-plate valve has reduced the problem of the bellows bursts that frequently causes because of valve opening and closing greatly.
The technical solution adopted in the utility model is:
The anti-leak blank-plate valve, comprise left valve barrel, middle valve body, right valve barrel, valve plate, valve plate Sealing, locking screw mandrel and locking nut, middle valve body places between left valve barrel and the right valve barrel, valve plate places between valve body and the left valve barrel, and seal by the valve plate Sealing, three valve body upper ends fuse by locking screw mandrel and locking nut, are connected with valve seal spare between middle valve body and the right valve barrel.
Described valve seal spare is a rubber seal, adopt two rubber seal be embedded in in the groove between valve body and the right valve barrel.
The utility model has removed original bellows structure and has adopted valve seal spare structure, thereby has reduced the problem of the bellows bursts that frequently causes because of valve opening and closing greatly.The utility model has adopted a kind of valve seal spare of rubber material for this reason, and sealing effect is good.
