Pulsed valve 
 Pulsed valve 
 Safety valve Model: GA49Y-4 
 Pulsed valve is mainly used for power plant boilers, pressure vessels, temperature and pressure reduction devices and other equipment to prevent the pressure exceeds the maximum allowed pressure to ensure the safe operation of equipment. 
 A pulsed valve Overview: 
 Pulsed valve is mainly used for power plant boilers, pressure vessels, temperature and pressure reduction devices and other equipment to prevent the pressure exceeds the maximum allowed pressure to ensure the safe operation of equipment. 
 Second, the structure outlined: 
 1, through the flap lever and weight to the pressure balance valve, the valve to ensure sealing, the location of mobile heavy hammer hammer weight and change to meet the requirements of the pressure off. 
 2, the sealing surface with the iron base made of chrome-nickel stainless steel welding, valve by heat treatment to improve 
 And erosion resistance. 
 3, with opening and closing the upper valve solenoid, mechanical and electrical action without disturbing each other. 
 Third, the pulse valve installation instructions: 
 1, the valve should A49H-4-type supporting the use of the main safety valve. 
 2, the pulse valve should be installed strictly vertical, the level of leverage should be maintained, with the sides oriented fork gap must be uniform. 
 3, the pulse valve prior to installation, the pipeline should be washed clean. 
 4, pulse valve leads to the main pipe and the inlet valve should be maintained between certain long distance, electric contact pressure gauge and the main valve between the inlet pipe distance not less than five times the diameter of the main valve inlet to avoid the main valve action, effects due to exhaust pressure gauge and safety valve pulse work is correct. 
 Fourth, the dimensions and connecting dimensions: DN 
 Ordering: 
 1, ① pulsed valve product name and model ② ③ diameter pulsed valve safety valve is pulsed with an attachment so we can correct for your selection. 
 2, if the unit has been selected by the design company Bing Qi valve pulse valve type, valve type, press pulsed direct order to our sales department. 
 3, very important when using the occasion or the environment is more complex when you try to provide detailed design drawings and parameters, Bing Qi valve by our experts to your company's audit checks.
