Problems solved by technology

The disadvantage is that the resistance is large and the sealing is poor when closed
[0003] After the check valve has been used for a long time, it is prone to clogging. When cleaning the existing embedded check valve, it needs to be disassembled before cleaning, and the operation is more cumbersome

Abstract

The invention discloses a novel embedded check valve, which comprises a valve body, a water inlet pipe and a water outlet pipe. One end of the valve body is provided with a water inlet pipe, and the other end of the valve body is provided with a water outlet pipe. The port of the water pipe is welded with a flange, the upper end of the valve body is welded with an inner threaded pipe, and the inner threaded pipe communicates with the inside of the valve body, and a decontamination pipe is provided at the lower end of the valve body, and the decontamination pipe communicates with the valve body. The inside of the valve body, and the port of the decontamination pipe is welded with a flange, close the liquid in the pipe, unscrew the threaded plug, open the sealing plate at the mouth of the decontamination pipe, inject water into the valve body from the inner threaded pipe, The inside of the valve body is cleaned, and the cleaned water is discharged from the decontamination pipe, which facilitates the cleaning of the valve body.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a novel embedded check valve. Background technique [0002] Check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. It is an automatic valve, also known as a check valve, a one-way valve, a return valve or an isolation valve. The movement mode of the valve disc is divided into lift type and swing type. The lift check valve is similar in structure to the globe valve, except that it lacks the valve stem that drives the valve disc. 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 weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The swing check valve has a disc that is inclined and can rot...
