DIN Type Safety Overflow Valve/Cast Iron Safety Valve

Safety valve is a safety protection valve, its opening and closing parts under the external forces under the normal closed state, when the equipment or pipe in the media pressure rise, beyond the specified value of automatic opening, through the discharge of media outside the system to prevent the pipe or equipment in the media pressure beyond the specified value.

The safety valve belongs to the automatic valve class, mainly used in boilers, pressure vessels and pipes, the control pressure does not exceed the specified value, and plays an important protective role for personal safety and equipment operation. Safety valves are important safety accessories for boilers, pressure vessels and other pressure-affected equipment and should be inspected frequently to make them safe and reliable. Its movement reliability and performance are directly related to equipment and personal safety, and is closely related to energy conservation and environmental protection. And some users and design departments in the selection, always choose the wrong model.

In this paper, the selection of safety valve is analyzed.

The safety valve (Safety Valve, also known as the pressure relief valve Relief Valve) is based on the pressure system operating pressure (operating temperature) automatic opening and closing, generally installed in the closed line of the set safety valve To secure the system on the way or on the pipe.

When the pressure or temperature in the equipment or pipe exceeds the pressure set by the safety valve, automatically turn on the pressure relief or cooling, to ensure that the equipment and pipe medium pressure (temperature) under the set pressure (temperature), to protect the normal operation of equipment and piping, to prevent accidents, reduce losses.
