Problems solved by technology

When the applicant undertook the design and manufacture of the nitrogen purge valve for the KANDHKOT Gas Field Natural Gas Compression Station (KFGCS) project of Pakistan Petroleum Corporation, the applicant required the valve to have functions such as double isolation, discharge, and automatic prevention of medium backflow, which was not available in the prior art. A valve with a structure can have several different functions at a certain position in the pipeline, and a valve with a single function cannot meet the requirements of multiple functions

Abstract

The invention provides a novel multifunctional valve which comprises a valve body, wherein a medium inlet end and a medium outlet end of the valve body are respectively provided with a ball valve, and a throttling stop valve is arranged at a shunt valve on the side wall of the valve between the two ball valves. A piston type check valve is arranged in front of the ball valve at the medium inlet end of the valve body. The multifunctional valve has compact and novel structure, and integrates multiple functions. Different functions of valves are integrated in one valve body, and the multifunctional requirements in the use process can be met through controlling corresponding valves and carrying out different combinations.

Description

technical field [0001] The invention belongs to the technical field of valve manufacturing and relates to a novel valve integrating multiple functions. Background technique [0002] There are many types of valves, and different types of valves have different functions. Each valve has a specific structure that enables it to achieve a specific function. When the applicant undertook the design and manufacture of the nitrogen purge valve for the KANDHKOT Gas Field Natural Gas Compression Station (KFGCS) project of Pakistan Petroleum Corporation, the applicant required the valve to have functions such as double isolation, discharge, and automatic prevention of medium backflow, which was not available in the prior art. A valve with a structure can have several different functions at a certain position in the pipeline, and a valve with a single function cannot meet the requirements of multiple functions. Contents of the invention [0003] The purpose of the present invention is ...
