Description

Ultrahigh-pressure integrated double-check and flow path conversion device

Technical Field

The utility model relates to the technical field of check valves, in particular to an ultrahigh pressure integrated double-check and flow path conversion device.

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 for driving the 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 disadvantage is the high resistance and the poor tightness when closed.
