(1) The original sleepiness is generated: no attention is paid to daily maintenance and cleaning, so that the debris contaminates the pressure reducing valve, and a small round hole with a diameter of about 1mm is blocked in the upper shell. The small round hole is a breathing hole, which communicates with the upper surface of the rubber membrane in the pressure reducing valve. When the diaphragm moves up and down, air continuously enters and exits from the breathing hole to achieve pressure regulation. If the breathing hole is blocked, the air above the diaphragm cannot enter and exit normally, resulting in the failure of LPG pressure adjustment, causing the high-pressure LPG to directly supply air, causing the flame of the burner to suddenly increase or escaping from the fire and exhausting the gas, resulting in fire or poisoning. accident.

(2) Treatment method

Check and clean frequently to keep the breathing holes open. When leaking liquefied petroleum gas is found in the breathing hole, it indicates that the rubber membrane has been damaged. Close the angle valve immediately, remove the pressure relief valve, replace the diaphragm or replace with a new pressure relief valve.
