Industrial gas valves are an important part of any pipeline system, which means they play a key role in the oil and gas industry. They can be used to control flow rates, isolate and protect equipment, and direct and guide the refining process of crude oil. In this article, we will introduce some knowledge about industrial gas valves.
1) A brief introduction to the industrial gas valve
2) Application areas of the industrial gas valve
3) Sealing requirements of the industrial gas valve
Industrial gas valves are flow control devices for handling and controlling the flow of gases such as liquefied petroleum gas, oxygen, acids and natural gas. They are available in a wide range of metal or plastic materials, compatible with media control and pressure requirements. Gas valves are available in most basic valve technologies such as ball valves, butterfly valves, plug valves, needle valves and various check valve designs. They are used in on/off, modulating and control applications in many industrial, commercial and residential applications.
What is the industrial gas valve used for? Industrial gas valves are used in a variety of applications and industries. Examples include-
Pulp and Paper
High purity gas valves for handling gases such as nitrogen, argon, oxygen and hydrogen.
The sealing performance of industrial gas valve refers to the ability of the sealing parts of the valve to stop the leakage of the medium, it is the most important technical performance indicators of the valve. industrial gas valve has three sealing parts: the contact between the opening and closing parts and the two sealing surfaces of the valve seat; the packing and the stem and stuffing box; the connection between the valve body and the valve cover. One of the former leakages is called internal leakage, which is usually referred to as closed, it will affect the ability of the valve to cut off the medium. For the cut-off valve class, internal leakage is not allowed. The last two leaks are called external leakage, that is, the media from the valve leakage to the outside of the valve. External leakage will cause material loss, pollution of the environment, and in serious cases, will cause accidents. For flammable and explosive, toxic or radioactive media, external leakage is not allowed, so industrial gas valves must have a reliable sealing performance.
Other requirements of an industrial gas valve:
1. Assembly of the completed industrial gas valve with nitrogen gas purge at least 1 minute.
2. Gas-tight test must be with pure nitrogen.
3. After the gas-tight test is passed, the industrial gas valve is sealed with a clean polyethylene cap, which should be soaked in organic solvent and wiped clean before use.
4. Then use a vacuum bag for sealing.
5. Finally boxed.
6. Take measures to ensure the package seal is not broken during transportation.
