Product Description

GA49H pulse safety valve

GA49H pulse type safety valve is mainly used in power plant boilers, various pressure vessels, temperature and pressure reduction devices and other equipment, to prevent the equipment pressure exceeds the allowable value of timely pressure relief, to ensure the safe operation of equipment.
Working principle
Pulse type safety valve in addition to the above mechanical action, the pulse valve is also equipped with electromagnetic device, the pressure gauge of the charged contact through the time relay, the upper or lower electromagnetic coil circuit is connected, so that the upper or lower electromagnet action, the pulse valve can also be opened or closed. At the same time, the pulse valve can also be artificially opened or closed through the remote control system.
When running, the main safety valve of this safety valve depends on steam pressure and spring force to press the spool upward on the seat, with good tightness.

Scope of application

Urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection

Main features

The main structural characteristics of the impulse type safety valve are:
1, through the lever and weight to balance the pressure of the valve disc, so that the valve to ensure sealing, move the position of the weight and change the weight of the weight to achieve the required take-off pressure.
2, GA49H pulse type safety valve sealing material is made of iron-based chromium-nickel stainless steel surfacing welding, valve flap after heat treatment, improve wear resistance and erosion resistance.
3, GA49H pulse type safety valve valve with opening and closing of the upper part of the electromagnet, mechanical and electrical action do not interfere with each other.

Installation instructions

1, GA49H pulse type safety valve should be used with A69Y-Pw5410V, DN150 main safety valve, etc.
2, the installation of the pulse safety valve should be strictly vertical, the lever should be kept horizontal, the pipeline should be washed clean.
3, GA49H pulse safety valve outlet tube and the main safety valve inlet tube should be maintained between a long distance, the distance between the electric contact pressure gauge and the main safety valve inlet tube, not less than 5 times the main safety valve inlet pipe diameter, so as to avoid the main safety valve action, due to exhaust steam affect the electrical contact pressure gauge and pulse safety valve work is correct.
4, GA49H pulse type safety valve and electromagnet together installed on a special bracket, valve lever and electromagnet connection to be flexible, there should be no card phenomenon.

Structure brief description

1, through the lever and weight to balance the pressure of the valve disc, so that the valve to ensure sealing, 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 surfacing welding, the valve flap after heat treatment, improve the wear resistance and erosion resistance.
3, the upper part of the valve with open and close electromagnet, mechanical and electrical action do not interfere with each other.
