Ga49h pulse safety valve product introduction:

Ga49h pulse safety valve is mainly used for power station boilers, pressure vessels, temperature and pressure reduction devices and other equipment to prevent the pressure from exceeding the allowable maximum pressure value and ensure the safe operation of the equipment.

Application range of ga49h pulse safety valve:

Pulse type safety valves are mainly used for power station boilers, pressure vessels, temperature and pressure reduction devices and other equipment.

Structural features of ga49h pulse safety valve:

1. Balance the pressure of the valve disc through the lever and the weight to ensure the sealing of the valve, move the position of the weight and change the weight of the weight to achieve the required take-off pressure.

2. The sealing surface is made of iron-based chromium nickel stainless steel by surfacing welding. The valve disc is heat treated to improve the wear resistance and erosion resistance.

3. Ga49h pulse safety valve is equipped with opening and closing electromagnets on the upper part, and the mechanical and electrical actions do not interfere with each other.

Installation instructions for ga49h pulse safety valve

1. Pulse type safety valve shall be used together with a49h-4 main safety valve.

2. When installing the pulse safety valve, it should be strictly vertical, the lever should be horizontal, and the gap between the lever and the two sides of the guide fork must be even.

3. Before installing the pulse safety valve, flush the pipeline.

4. A long distance should be kept between the outlet pipe of the pulse safety valve and the inlet pipe of the main safety valve. The distance between the electric contact pressure gauge and the inlet pipe of the main safety valve should not be less than 5 times the inlet pipe diameter of the main safety valve, so as to prevent the correctness of the electric contact pressure gauge and the pulse safety valve from being affected by steam exhaust when the main safety valve acts.
