Application field of shut-off valve
Author:
1. oil industry
In the petroleum industry, the shut-off valve is often used in oil field pipeline, oil and gas well switch and control, and oil and gas separation system in the filtration, water level control and so on. At the same time, the use of shut-off valves can not only improve safety, but also help improve production efficiency and save energy.
2. chemical industry
The cut-off valves commonly used in the chemical industry are knife gate valves, globe valves, butterfly valves, etc., for different media cut-off and control. For example, knife gate valves are usually used for high temperature and high pressure, containing particles and high viscosity media, while butterfly valves are suitable for low pressure, low temperature, medium viscosity and pure media.
3. metallurgical industry
In the metallurgical industry, the cut-off valve also has a wide range of applications. For example, the cut-off valve used to control the molten steel, the inlet and outlet cut-off valve of the weighing tank, etc. These valves need to withstand the test of harsh environments such as high temperature and high pressure, and need to be stable and reliable.
4. Construction Industry
The shut-off valve also has a wide range of applications in the construction industry. For example, it is used for the shut-off valve of indoor water pipe, the shut-off valve of gas pipeline, the shut-off valve of air conditioning pipeline, etc. These valves not only need beautiful appearance, but also must be stable and reliable, and easy to operate.
In summary, the shut-off valve is a very common type of valve, widely used in petroleum, chemical, metallurgy, construction and other fields. In these areas, the application of shut-off valves can improve production efficiency, ensure the safety of equipment and workers, and reduce energy consumption.

Gas self-closing valve, can you use it?
The gas self-closing valve is installed on the indoor gas pipeline of residents. It is generally installed behind the gas meter and in front of the gas appliance. When the gas supply pressure of the gas pipeline is under-pressure or over-pressure, it will automatically close without electricity or other external power. Cut off the gas source, which can effectively prevent gas leakage and issuance accidents.
