[0002] Valve pipe fittings include two parts: valves and pipe fittings. They jointly act on the connection or control system of pipelines and are key components used in pipeline systems in the oil and gas industry. Valves are mainly used to control and regulate the flow rate and pressure of fluids, while pipe fittings play roles such as connection, control, and direction change. In oil and gas fields, these valve pipe fittings need to withstand the tests of high pressure, high temperature, and corrosive media.
[0003] In the current existing technology, since the valve pipe fittings achieve the heat preservation function by arranging a heat preservation layer inside, and these pipe fittings are usually fixed by means of bolt connection. However, bolt connection takes a lot of time during disassembly and assembly. When the heat preservation layer inside the valve pipe fittings is damaged and needs to be replaced, it is extremely cumbersome, time-consuming and laborious, reducing the working efficiency during replacement and making it inconvenient to disassemble and replace the valve pipe fittings. Content of the Utility Model
