Abstract
The utility model relates to a stop valve which comprises a valve body, a valve cover and a valve rod and is characterized in that a flange is mounted at the joint of the valve body and a pipeline. The utility model solves the problems the prior stop valve after being used for a long period of time is inconvenient to dismount and maintain and the utility model is suitable for the flow control of liquid and gas.
Description
Technical field:
The utility model relates to the flow control field of fluid line, the flow control valve of specifically a kind of liquid, gas.
Background technique:
At present society goes up that its connection form of stop valve that design produces is mostly taked to weld or the form of screw thread, and its shortcoming is to be not easy to dismounting, maintenance after long-term the use and to change, and disposable use is wasted bigger.
Summary of the invention:
The problem of the utility model for being not easy to after solving that common valve is long-term and using dismantle and keep in repair invented a kind of valve that has flange coupling.
The technical solution of the utility model is, a kind of stop valve comprises valve body, valve gap, valve rod, and its special way is: valve body and pipe link mouth place mounting flange.
The flap that cooperates with sealing surface is housed in valve body, valve body and valve gap bolted on connection, valve rod is equipped with at the valve gap middle part, and valve rod lower end and flap connect, and Stem Mut is equipped with on valve rod top, and the Stem Mut upper end connects with handwheel.
During maintenance, the bolt at dismounting flange and pipe link place takes out valve.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize a kind of be convenient to dismantle maintenance and the liquid of changing, the flow control valve of gas.
