Safety valve selection principles

Safety valve selection principles
1, air or other gas stove safety valve, generally used in the entire Kai spring safety valve;
2, high-pressure bypass valve steam generating equipment, generally used in a safe and controlled dual function of the Pilot Safety Valves
3, if the medium temperature is higher, in order to reduce the temperature of the spring chamber, usually enclosed safety valve when the temperature exceeds 300 ℃ and open valve temperature than 350 ℃ and should be used in safety valve with radiator;
4, if the medium is corrosive and should be used bellows safety valve, preventing the important parts due to media corrosion and failure.

Boiler safety valve is an important safety equipment

Gas safety valve is an important safety accessories pressure vessels and other equipment under pressure. Safety valve (also known as pressure relief valve) is automatically open and close depending on the pressure system operating pressure (temperature), usually installed in equipment pipeline protection system security or closed system. When the equipment or pipeline pressure or temperature exceeds a set pressure relief valve, pressure relief or cooling automatically open to ensure that equipment and the pipeline medium pressure (temperature) is below the set pressure (temperature), protective equipment and piping work, prevent accidents and reduce losses.

Gas Burner Safety Valve is the valve of a special branch

Gas Burner Safety Valve is the valve of a special branch of the family, it's particularity is because, unlike other gas burner valve switch just to play the role, more importantly protect the safety of the device. With the rapid development of China's economic construction, the project works with a pressure control equipment is increasing. Given the need for pressure relief devices, safety plays a crucial role in the protection device process.

Gas safety burner valve in a normally closed state

Gas Burner Safety Valve is opening and closing pieces by the external force in a normally closed state when the device or media pressure inside the pipe rises above a predetermined value, through to the outside of the system to prevent the discharge medium medium pressure piping or equipment exceeds a predetermined value special valves. Safety valves are automatic valves, mainly used in boilers, pressure vessels and piping, control pressure does not exceed a predetermined value, for personal safety and equipment operation plays an important protective role. Note the safety valve must be pressure tested before use.
