Household liquefied gas problem?

High-pressure valve and low-pressure valve are collectively referred to as pressure reducing valve. The difference is that the output pressure of the high-pressure valve is high and the flow rate is large (the output pressure is adjustable, and the ejector pin precession pressure is high, otherwise it is low), while the output pressure of the low-pressure valve is low and the flow rate is small. 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. The high-pressure valve is used for commercial gas stoves, such as gas stoves in restaurants, with high output pressure. Low-pressure valve is usually called pressure reducing valve, which is used by ordinary liquefied gas bottles and is used to connect domestic gas stoves.
