Description

Technical Field

[0001] The utility model relates to the technical field of pipe clamp valves, in particular to an impurity-proof pipe clamp valve. Background Art

[0002] The pipe clamp valve is also called the pipe clamp valve, air bag valve, clamp valve, etc. It is mainly used in pipelines to cut off the flow of media. The casing (i.e., hose) is the most important part of the pipe clamp valve and the core of the pipe clamp valve. It has corrosion resistance, wear resistance and pressure bearing capacity. Therefore, the quality of the casing often determines the quality of the pipe clamp valve. The casing can be squeezed by pneumatic, electric, manual or hydraulic driving methods to achieve the function of switching and regulating the flow of the medium. When the pipe clamp valve conveys materials, solid particulate impurities will be mixed inside the pipe clamp valve.

[0003] The patent with application number 202223549757.5 discloses an impurity-proof pipe clamp valve mechanism, which includes a valve body assembly, a filter assembly and a backwash assembly. The valve body assembly is equipped with a hose; the filter assembly is connected to the valve body assembly; the filter assembly is equipped with a truncated cone funnel, and the small end of the truncated cone funnel is connected to the hose; the backwash assembly is connected to the hose; the backwash assembly can make the medium in the hose flow in the reverse direction to flush the hose and the filter assembly. Impurities in the valve body assembly can be flushed back into the filter assembly, ensuring that the inner wall of the hose is clean before the valve is closed, thereby effectively avoiding the situation where the hose is damaged by impurities stuck in it due to the valve closing.

[0004] However, the backwash assembly in this technical solution corresponds to the tube clamping unit. When the filter plate is cleaned, the tube clamping unit will block the flushing water flow in the backwash assembly, resulting in poor cleaning effect of the backwash water flow on the filter plate. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and provide an impurity-proof pipe clamp valve, which realizes the function of cleaning and disassembling the filter plate for cleaning through multiple flushing hole structures located on both sides of the filter plate in conjunction with a detachable water outlet pipe structure, thereby solving the problem of poor cleaning effect of the filter plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impurity-proof pipe clamp valve, comprising a pipe clamp valve body and an inlet pipe and an outlet pipe installed at both ends of the pipe clamp valve body, a second flange is provided at both ends of the pipe clamp valve body, a cleaning channel is fixed in the outlet pipe, and a first flange is provided at both ends of the outlet pipe, a plurality of fastening rods are fixed to the side wall of the first flange, a cleaning pipe is installed between the cleaning channel and the inlet pipe, and a filter plate is fixedly installed at the center position of the inner wall of the cleaning channel, wherein both sides of the inner wall of the cleaning channel are provided with flushing holes facing the filter plate in a circular array.

[0007] Preferably, a rotating disk is installed on the tube clamp valve body, and sealing rings are embedded at both ends of the tube clamp valve body.

[0008] Furthermore, the two sealing rings are respectively in contact with the side walls of the water inlet pipe and the water outlet pipe, and the side wall of the pipe clamp valve body is provided with a plurality of bolts connecting the second flange and the water inlet pipe.

[0009] Furthermore, a solenoid valve is installed at one end of the cleaning pipe, and a pipeline connecting part is provided at the other end of the cleaning pipe.

[0010] Furthermore, the fastening rod is inserted into the second flange, and positioning blocks that abut against the side walls of the second flange are elastically provided on both sides of the outer wall of the fastening rod.

[0011] Furthermore, telescopic grooves are provided on both sides of the outer wall of the fastening rod, the positioning block is slidably inserted in the telescopic grooves, and the positioning block is protruding from the outer wall of the fastening rod.

[0012] Furthermore, an elastic plate is embedded in the telescopic slot, and two ends of the elastic plate are respectively connected to the positioning block and the inner wall of the telescopic slot.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model has a cleaning channel installed on the water outlet pipe, and a cleaning pipe installed between the water inlet pipe and the cleaning channel. When cleaning the filter plate, the pipe clamp valve body is closed by a turntable, and the solenoid valve is opened. The water in the water inlet pipe is sprayed out from the flushing hole through the cleaning pipe and the cleaning channel, and the two sides of the filter plate are flushed after being sprayed out. The sewage generated during the flushing process is discharged from the water outlet pipe, which is convenient for flushing the two sides of the filter plate, thereby improving the cleaning effect of the filter plate.

[0015] (2) The utility model installs a plurality of fastening rods on the side wall of the first flange on the water outlet pipe. When impurities on the filter plate are difficult to be rinsed off, the cleaning pipe between the cleaning channel and the water inlet pipe is separated through the pipe connection part, and the positioning block is squeezed from the outer wall of the fastening rod to shrink it into the telescopic groove, and the plurality of fastening rods are removed from the second flange, so that the water outlet pipe and the filter plate therein can be disassembled and cleaned. After cleaning, the plurality of fastening rods are inserted into the second flange until the side wall of the water outlet pipe abuts against the sealing ring and the positioning block completely passes through the second flange. The elastic plate in the telescopic groove pushes the positioning block to protrude from the side wall of the second flange, so that the water outlet pipe remains fixed on the pipe clamp valve, which facilitates the installation and disassembly of the water outlet pipe with the filter plate installed, thereby improving the convenience of cleaning the filter plate.

[0016] In summary, the utility model has the advantages of improving the cleaning effect of the filter plate and facilitating the cleaning of the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS
