A quick detachable check valve

Abstract

The invention relates to a check valve capable of being quickly disassembled. The check valve comprises a telescopic main pipe, a unidirectional filter, a connecting barrel, a first connecting pipe and a second connecting pipe, the unidirectional filter is arranged at the left end of the telescopic main pipe, the first connecting pipe is arranged at the left end of the unidirectional filter, the connecting barrel is installed at the right end of thetelescopic main pipe, and the second connecting pipe is arranged at the right end of the connecting barrel. According to the check valve capable ofbeing quickly disassembled, the difficult problems that according to existing check valves, the check valves are needed to be rotated to be connected with external pipelines, when being assembled anddisassembled, due to the narrow distance reserved between the pipelines on the two edges, the existing check valves are difficult to assemble and disassemble, during use of the existing check valves,large particulate impurities are unavoidable in flowing fluid, the pipelines can be blocked during long-term flowing of the fluid, and clearing is difficult can be solved.

Description

technical field [0001] The invention relates to the field of valves, in particular to a quickly detachable check valve. Background technique [0002] Check valve is one of many pipeline valves. Check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the medium from flowing backward. It is also called check valve, one-way valve, reverse flow valve, And back pressure valve, check valve belongs to a kind of automatic valve, its main function is to prevent medium backflow, prevent pump and drive motor from reversing, and release container medium. The present invention is aimed at plastic horizontal check valve. [0003] However, the existing check valve has the following defects during installation and disassembly: 1. It is necessary to rotate the check valve itself to connect with the external pipeline; 2. During installation and disassembly, due to the narrow distance between the pipelines on both sides , ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a check valve that can be quickly disassembled, which can solve the problem that the existing check valve needs to rotate the check valve itself to connect with the external pipeline. The distance between them is relatively narrow, and the existing check valve is difficult to install and disassemble. When the existing check valve is used, the flowing liquid will inevitably have large particles of impurities, which will block the pipeline during long-term flow, making it difficult to clean and other problems.
