Description

Check valve convenient to dismantle and overhaul
Technical Field
The utility model relates to the technical field of check valves, in particular to a check valve convenient to detach and overhaul.
Background
The check valve is a valve with a circular valve clack as an opening and closing part and can stop the medium from flowing backwards by the action of the self weight and the medium pressure. Belongs to automatic valves, which are also called check valves, one-way valves, reflux valves or isolation valves. The movement modes of the valve clack are divided into a lifting type and a swing type. The lifting check valve is similar to a stop valve in structure, and only lacks a valve rod 3 for driving a valve clack. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the valve flap weight and its flow resistance, the valve is opened. Otherwise, the valve is closed when the medium flows backwards. The swing check valve has a valve clack which is inclined and can rotate around the shaft, and the working principle is similar to that of the lifting check valve. Check valves are commonly used as bottom valves for pumping devices to prevent backflow of water. The check valve and the stop valve are combined for use, so that the safety isolation function can be realized. The check valve may also be used on a line to provide makeup to auxiliary systems where the pressure may rise above the system pressure. The check valves are mainly classified into swing check valves (rotated about the center of gravity) and lift check valves (moved along the axis).
