Description
Technical field
The utility model relates to a kind of outlet valve, relates in particular to a kind of automatic control pressure vent.
Background technique
Outlet valve is requisite device on pipeline, for getting rid of pipeline internal gas, but in the process of exhaust, because the medium liquid level in pipeline is higher than relief opening, will cause medium to flow out from outlet valve.In carrying out exhaust, just need to manually operate like this, open drain tap, see when having MEDIA FLOW out throttle down at once, such operation is very inconvenient, and can not be real-time carry out exhaust, cause operator's workload very large, wasting manpower and material resources.
Model utility content
The purpose of this utility model is: in order to address the above problem, provide a kind of automatic control pressure vent simple in structure, easy to use, it can automatic vent, and can prevent that the medium of pipe interior from overflowing.
To achieve these goals, the technical solution of the utility model is:
A kind of automatic control pressure vent, comprises base, housing and ball float; Described base is provided with the first through hole; Described first through hole one end arranges plug, and the other end is provided with circular abutment; Described circular abutment inside arranges the second through hole; Described circular abutment one end is provided with circular groove, and the other end arranges outside thread; Described circular abutment is connected with described the first through hole by described outside thread; In described circular groove, be provided with piston head; Described circular abutment side is provided with bearing; Described base is provided with hemispherical groove; Described ball float is arranged in described hemispherical groove; Described ball float is provided with guide rod; Described guide rod is connected in described bearing by first connecting rod and second connecting rod, and rotates around described bearing; Described first connecting rod one end is connected in described guide rod, and the other end is connected in described bearing; Described second connecting rod one end is connected in described guide rod, and the other end is connected in described piston head, and centre is connected in described bearing.
Further, described base bottom is provided with import; Described chassis side is provided with outlet; Described outlet is connected with described the first through hole.
Further, described bottom portion of groove is also provided with the round gasket of hollow.
Further, described base is connected by bolt with housing.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model is owing to being provided with ball float in valve body, the connecting rod being attached thereto drives the piston head in circular abutment to move, thereby realize closing and opening of relief opening, when pipe interior liquid level moves liquid level lower than ball float, gas in pipeline can be discharged smoothly by the second through hole in circular abutment, the first through hole and outlet, when liquid level moves liquid level higher than ball float, ball float drives piston head to move down, seal the first through hole, avoid the medium in pipeline to discharge in the first through hole.The utility model is owing to being provided with the round gasket of hollow in groove, the sealability while having ensured to close.
