Low-pressure valves are generally used for household gas stoves or water heaters, and high-pressure valves are used for high-power gas stoves in restaurants.
The water heater uses a high-pressure valve, because the pressure is high and the flow rate is fast. If it cannot be ignited, it is likely to release gas into the air. When the water heater ignites the gas mixture again, it will explode, not the gas bottle, but also indirectly. Simply put, the low-pressure valve can control the pressure of the tank and release the gas bit by bit. Even if the adjusting screw is unscrewed, the gas released will not be very large.
Extended data:
Working principle of pressure reducing valve:
The pressure reducing valve adjusts the flow rate of the medium by controlling the opening and closing parts in the valve body to reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the pressure behind the valve to keep the pressure behind the valve within a certain range, and cooling water is injected into the valve body or behind the valve to reduce the temperature of the medium. This kind of valve is called decompression and desuperheating valve.
Includes automatic selection of pressure reducing valve. The characteristic of this valve is to keep the outlet pressure and temperature within a certain range when the inlet pressure is constantly changing.
Application performance of high pressure valve:
The high-pressure safety valve is suitable for water, steam and air medium pipelines. Through adjustment, the inlet pressure is reduced to a required outlet pressure. When the inlet pressure and flow rate change, the outlet pressure is automatically kept within a certain range by the energy of the medium itself, but the difference between the inlet pressure and the outlet pressure must be ≥0.2MPA/CM.
