[0002] A natural gas pipeline is a pipeline that transports natural gas (including associated gas produced in oil fields) from the extraction site or processing plant to the city's gas distribution center or industrial enterprise users. In order to facilitate the control of pipeline pressure, technicians will install pressure regulating equipment at the connection of the natural gas pipeline.

[0003] After searching, the existing announcement number CN216976121U is a kind of pressure regulating device for natural gas pipeline, and its technical scheme includes: connecting pipe, mounting pipe, pressure regulating valve, sleeve, ring block, fixed ring and sleeve ring. Mounting pipes are arranged at both ends of the pressure regulating valve, and a fixed ring is arranged inside the mounting pipe. A ring groove is opened inside one end of the fixed ring, and a connecting pipe is inserted inside the fixed ring. The outer wall of the connecting pipe is sleeved with a sleeve ring, and a sealing ring is arranged on the outer wall of one end of the sleeve ring. A sealing gasket is arranged on the inner wall of the ring groove, and a sleeve is sleeved on the outer wall of the mounting pipe. A rotating block is arranged on the inner wall of the sleeve, and a ring block is arranged inside the sleeve, and a pressure ring is arranged at one end of the ring block. The sleeve ring is squeezed by the pressing block driven by rotating the sleeve. When the sealing ring and the fixed ring are tightly fitted, the connecting pipe and the regulating valve are fixed together, and the sealing effect of the connecting pipe and the regulating valve is better with the two-layer sealing gasket, and the installation is more convenient.

[0004] After installing the regulating valve relative to the natural gas pipeline, there is a gap between the regulating valve and the supporting surface, which makes the support unstable and affects the subsequent use effect. Therefore, we propose a pressure regulating device for natural gas pipelines to solve the above problems. Utility Model Content
