GA49H Pulse Safety Valve
Other Products
I. Product Introduction:
The GA49H pulse safety valve is mainly applied to equipment such as power station boilers, various pressure vessels, and temperature and pressure reducing devices. It can release pressure in time when the equipment pressure exceeds the allowable value, ensuring the safe operation of the equipment. During operation, the main valve of this safety valve presses the valve core upward against the valve seat by steam pressure and spring force, providing excellent sealing performance. It is applicable to the urban construction, chemical, metallurgical, petroleum, pharmaceutical, food, beverage, and environmental protection industries. In addition to the above mechanical actions, the pulse safety valve is also equipped with an electromagnetic device. The pressure gauge with electrical contacts connects the upper or lower electromagnetic coil circuit through a time relay, actuating the upper or lower electromagnet, which can open or close the pulse valve.
II. Product Features:
1. Balance the pressure of the valve disc through a lever and a weight, ensuring the valve is sealed. Adjust the position of the moving weight and change the weight of the weight to achieve the required opening pressure.
2. The sealing material of the GA49H pulse safety valve is surfaced with iron-based chromium-nickel stainless steel. The valve disc undergoes heat treatment, which improves its wear resistance and erosion resistance.
3. The upper part of the GA49H pulse safety valve is equipped with an electromagnet for opening and closing, so the mechanical and electrical actions do not interfere with each other.
III. Product Principle:
In addition to the above mechanical actions, the pulse safety valve is also equipped with an electromagnetic device. The pressure gauge with electrical contacts connects the upper or lower electromagnetic coil circuit through a time relay, actuating the upper or lower electromagnet, which can open or close the pulse valve. Meanwhile, the pulse valve can also be opened or closed manually via a remote control system.
