A wear-resistant ball valve capable of high temperature and high pressure

Abstract

The invention relates to a high temperature and high pressure wear-resistant ball valve, which includes a valve body, a control hole is opened on the upper end of the valve body, a control assembly is arranged in the control hole, an executive assembly is installed on the lower end of the control assembly, and the executive assembly is arranged on the valve body. in vivo. The present invention can solve the following problems existing in the process of controlling the transportation of oil and gas using ball valves. a. The existing ball valves are mainly made of metal materials, and the friction between the parts of the ball valves is high. Frequent use is prone to mechanical wear, resulting in the failure of normal use of the ball valves. b. The airtightness of the ball valve is high when transporting gas, but the airtightness of the existing ball valve is easily damaged due to wear and tear during use, and the wear resistance is poor, which easily leads to oil and gas leakage, which poses a safety hazard.

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.
