Description

Technical Field

[0001] This utility model relates to the field of ball valve protection technology, and in particular to a pneumatic ball valve with a protection mechanism. Background Technology

[0002] With the continuous development of industry, the requirements for valves in various industrial scenarios are becoming increasingly stringent. In industries such as petroleum, chemical, metallurgy, and power, valves need to work in harsh environments such as high temperature, high pressure, strong corrosion, and high dust. For example, in petrochemical production, the medium is often corrosive, and ordinary pneumatic ball valves are easily damaged by corrosion, affecting production safety and efficiency. In order to adapt to these complex working conditions, pneumatic ball valves need to be protected to extend their service life and ensure their stable performance.

[0003] However, under certain operating conditions, pneumatic ball valves may generate heat during operation. While the protective mechanism protects the valve, it may also affect the dissipation of heat. If the heat cannot be dissipated in time, it may cause the internal temperature of the valve to rise, affecting the valve's performance and service life, and may even affect the flow of the medium.

[0004] Therefore, we provide a pneumatic ball valve with a protective mechanism to solve the above problems. Utility Model Content
