Description

Check valve convenient to clearance intraductal plug

Technical Field

The invention relates to the technical field of check valves, in particular to a check valve convenient for cleaning a blockage in a pipe.

Background

The back valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The valve clack motion mode is divided into lifting type and swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves. The check valve is commonly used as a bottom valve of a water pumping device and can prevent the backflow of water. The check valve and the stop valve are used in combination, so that the safety isolation effect can be achieved;

the existing check valve is in long-term operation, and the normal work of valve body is influenced by the blockage of foreign matters inside the existing check valve, so that an operator is required to manually disassemble and assemble the check valve and manually clean the check valve, and when the traditional check valve is cleaned, the foreign matters in the valve cavity at the bottom side are deposited and are difficult to clean and discharge, so that a cleaning structure is lacked, and the operator is inconvenient to clean.
