1, The installation method is different:
High-pressure valves and low-pressure valves are generally used between water heaters or gas pipes. If the installation is reversed, it is easy to produce explosions and the like;
2. Different pressures:
The high pressure valve and the low pressure valve are collectively referred to as a pressure reducing valve. The difference is that the high pressure valve output pressure has a high flow rate, and the low pressure valve output pressure has a low flow rate;
3. Different uses:
Low-pressure valves are generally used in household gas stoves or water heaters, and high-pressure valves are used in high-power gas stoves in restaurants;
The high pressure valve is used for the water heater; because of the high pressure and high flow rate, it is very likely that the gas will not be released and the gas will be released into the air. The water heater will ignite again and ignite the mixture to generate an explosion. It is not a gas bottle explosion, and of course it will indirectly lead to the explosion of the gas bottle. .
Simply put, the low pressure valve can control the pressure of the tank, so that the gas is released a little bit, even if you screw off the adjusting screw, the gas will not be very large.
