Description
Technical field
The utility model relates to a kind of stop valve connecting cover.
Background technique
The open-shut device of stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, (adopted name: dark bar), also have lifting rotation rod-type, (adopted name: rising stem (RS.)) stop valve refers to the valve of closure member (flap) along the movement of valve seat center line.Stop valve is made up of the valve body of bottom and the valve gap on top, and valve gap is that use is cut in mounted valve switch and sealing, but general valve gap positioning precision is poor, and installation and maintenance bother, and sealing is poor.
Model utility content
For solving the problem, the purpose of this utility model is to provide that a kind of structure is simple, easy accessibility, cost easy to make are low, the stop valve connecting cover of good airproof performance.
For achieving the above object, the technical solution of the utility model:
A kind of stop valve connecting cover, comprise lid, arc-shaped cavity, fixing body, latch closure, projection, extension part, mounting hole, connecting head, under described lid, integral type is provided with fixing body, arc-shaped cavity is down had in lid, lid center has circular hole one, and run through lid, fixing body lower end is provided with the latch closure of annular, fixing body is also provided with projection, lid upper end is extension part, extension part upper end integral type is provided with connecting head, extension part has mounting hole, extension part both sides are provided with stiffening rib, the extension part of mounting hole both sides is provided with two pairs of fixed cover ears, circular hole two is had in connecting head.
As preferably, described lid, fixing body, extension part and connecting head are one-body molded for casting.
As preferably, described circular hole one and circular hole two are on the same line.
Beneficial conditions of the present utility model is: structure is simple, and easy accessibility, cost easy to make is low, good airproof performance.
