Use：
Mainly for the power station boiler, pressure vessel temperature and pressure reduction devices and other equipment to prevent the pressure exceeds the allowable maximum pressure value, to ensure the safe operation of the equipment.

Installation Instructions：
1、A49H-4.0-type main Anson valve, the valve should be supporting the use of works by levers and weights to balance the media, the pressure in the valve, causing the valve to ensure that the sealed move the hammer the position and change the hammer weight to meet the requirementstake off the pressure.
2、Pulse safety valve should be installed strictly vertical, leverage should remain level with the guide the fork both sides of the face gap must be uniform.
3、Before the pulse safety valve is installed, the pipe should be flush clean.
4、Pulse safety valve leads the inlet pipe of the tube and the main relief valve should be maintained between a longer distance, the distance between the inlet pipe of the pressure gauge with electric contact, and the main relief valve, not less than 5 times the main relief valve inlet. Avoidimpact due to exhaust the main safety valve, electric contact pressure gauge and the correctness of the pulse safety valve work.
