Common sense of structural form of emergency shut-off valve
Emergency cut-off valve is also called: emergency safety cut-off valve. Its structural forms include pneumatic, electric, hydraulic and electronic. They are respectively called: pneumatic emergency cut-off valve, electric emergency cut-off valve, hydraulic emergency cut-off valve, gas emergency cut-off valve, liquid ammonia emergency cut-off valve, ammonia emergency cut-off valve and ammonia emergency cut-off valve. Especially for the shut-off valve used for combustible media, the cylinder is basically blocked (fusible alloy) to prevent the tank from being damaged by high ambient temperature. It can be melted at 75 ± 5 ℃, and the shut-off valve is closed by pressure relief.

Due to different operation modes in different working conditions Emergency shut-off valve There is no unified standard for the structural form of, but we choose our own products according to the actual application on the site, such as hydraulic ones, manual oil pumps that need to be operated on the site, and pneumatic ones, which need to have air sources on the site. The electronic type can only be used in low pressure, electric type, and the actuator must be explosion-proof with manual function.
The emergency shut-off valve is installed in the ammonia station for fire safety inspection, and the gas station must be installed compulsorily, mainly to prevent fire or leakage. Since the manual valve cannot meet this requirement, the installation of emergency safety shut-off valve is to prevent accidents and prevent on-site personnel from entering. The valve that can cut off the flow of media can be remotely controlled to protect tank safety and personnel safety devices.
Emergency shut-off valve The model selection shall follow the five principles of safety, scientificity, reliability, applicability and economy, as well as the requirements of site working conditions, such as the size of valve diameter, working pressure, medium type, medium temperature, ambient temperature, power voltage, connection mode, installation mode, control mode, valve body material, special options, etc.
