Abstract
The utility model relates to a swing-type flange check valve, which comprises a valve body, a valve seat, a valve cover and a valve clack, and is characterized in that a flange is installed on the junction between the valve body and a pipeline. The swing-type flange check valve solves the problem that the opening and closing of ordinary valves are operated manually, and is applicable to the liquid flow-rate control.
Description
Technical field:
The utility model relates to the flow control field of fluid line, specifically a kind of flow control valve of liquid.
Background technique:
Society upward designs the valve of producing at present, connects pattern for welding and being threaded, and its shortcoming is to dismantle inconvenience.
Summary of the invention:
The utility model is invented a kind of valve that has flange coupling for solving the problem of the common valve welding and the troublesome poeration that is threaded.
The technical solution of the utility model is that a kind of rotary-open type flange safety check comprises valve body, valve seat, valve gap, flap, is valve body and pipe link mouth place mounting flange outside it is special.
Disk cover shape flap is housed on valve seat, on the outside of flap toggle is housed, the upper end of toggle is connected on the valve body by hinge, and flap is contained on the valve body.
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 automatic on-off control media refluence metered valve door.
