Description
Technical field
The utility model relates to conveying equipment for fluid substances field, is especially with manometric hand stop valve.
Background technique
Modern mechanical uses extensively, and various valve emerges in an endless stream, and hand stop valve is owing to washing away, and closing forces is not enough and Long-Time Service generation is expanded with heat and contract with cold causes not saying damage, is all not can solve all the time; Especially the real time environment in valve body is not known, very unfavorable to sealingly secure component protection.
Model utility content
The purpose of this utility model is to provide a kind of band manometric hand stop valve; mainly through valve seat being provided with the first valve body, the second valve body, pressure gauge, boss valve core and reducing parts; coordinate O-ring seals and packing ring; first and second seal ring makes component be monitored in real time; valve seal is improved; valve body is effectively protected, and improves working life, reduces economic loss.
In order to achieve the above object, the technical solution of the utility model is:
The manometric hand stop valve of a kind of band, comprises valve seat, described valve seat is provided with the first valve body, described first valve body is provided with the second valve body, and described first valve body second valve body is connected by pilot hole; Described second valve body is provided with valve gap, described valve gap is provided with valve-rod cavity, be provided with valve rod in described valve-rod cavity, described valve stem top is provided with handwheel, and described stem bottom is provided with boss valve core; On the left of described first valve body, pressure gauge is installed, right side opening is provided with osculum.
Be provided with the O-ring seals be connected with valve rod wall in described valve-rod cavity, be also provided with the packing ring be connected with valve rod wall in described valve-rod cavity, described O-ring seals is closely connected with packing ring.
Described pilot hole inwall is provided with the first seal ring, the second seal ring is installed in described boss valve core.
Intake tunnel is provided with the reducing parts suitable with boss valve core to described second valve body.
The beneficial effects of the utility model are: the manometric hand stop valve of one band of the present utility model; mainly through valve seat being provided with the first valve body, the second valve body, pressure gauge, boss valve core and reducing parts; coordinate O-ring seals and packing ring; first and second seal ring makes component be monitored in real time; valve seal is improved; valve body is effectively protected, and improves working life, reduces economic loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
