Wear-resisting ball valve capable of resisting high temperature and high pressure

Abstract

The invention relates to a wear-resisting ball valve capable of resisting high temperature and high pressure. The wear-resisting ball valve comprises a valve body. A control hole is formed in the upper end of the valve body. A control assembly is arranged in the control hole. An execution assembly is mounted at the lower end of the control assembly and is arranged in the valve body. According to the wear-resisting ball valve, the following problems that in the existing process of controlling the conveying process of oil gas through a ball valve, the existing ball valve is mainly made of a metal material, friction force between ball valve parts is large, mechanical wear is prone to happening due to frequent use, consequently, the ball valve cannot be used normally, the requirement for sealing performance is high when the ball valve conveys gas, during use of the existing ball valve, airtightness is prone to being damaged after wear, wear resistance is poor, oil gas leaking is prone to being caused, and potential safety hazards exist can be solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas valve transportation, in particular to a wear-resistant ball valve capable of high temperature and high pressure. Background technique [0002] Petroleum and natural gas are important material resources in our country. It is a relatively common way to use pipelines to utilize and transport oil and natural gas. Valves installed on pipelines can effectively control the effect of oil and gas transportation, and the use of valves directly affects the oil and gas. Safety in conveying operations. [0003] However, the existing oil and gas use ball valves to control the following problems in the transportation process. a. The existing ball valves are mainly made of metal materials. The friction between the parts of the ball valve is large, and frequent use is prone to mechanical wear, which makes the ball valve unable to work normally. b. The ball valve When transporting gas, the airtightness is req...

Problems solved by technology

[0003] However, the existing oil and gas use ball valves to control the following problems in the transportation process. a. The existing ball valves are mainly made of metal materials. The friction between the parts of the ball valve is large, and frequent use is prone to mechanical wear, which makes the ball valve unable to work normally. b. The ball valve When transporting gas, the airtightness is required to be high, and the existing ball valves are easy to damage the airtightness due to wear and tear during use, and the wear resistance is poor, which is easy to cause oil and gas leakage, and there are potential safety hazards

[0004] Regarding some problems of ball valves in oil and gas transportation operations, related industries have made research and proposed specific technical solutions, such as a Chinese utility model patent with a patent number of 2017207069825, which improves the structure of the lower valve stem. wear, which effectively improves the phenomenon of torque increase after the ball valve is frequently opened. However, some of the problems mentioned above about the ball valve in oil and gas transmission operations have not been involved.
