Why Should A Pressure Reducing Valve Be Installed On A Gas Cylinder
The pressure reducing valve of household gas cylinders is also called low-pressure valve. The standard name is household bottled liquefied petroleum gas pressure regulator. It is used in thousands of households and is closely related to our life safety.
The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjustment, and relies on the energy of the medium itself to automatically keep the outlet pressure stable.
From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction.

Low-pressure valve, medium-pressure valve, high-pressure valve
Taboos in using pressure reducing valves
The pressure in the gas cylinder is relatively high. If it is directly connected to the stove, it will cause the stove flame to burn unstable; second, high pressure directly connected to the stove will cause safety hazards, and excessive pressure will easily cause leakage during combustion; third, a large amount of gas rushes out to produce a strong flame, which greatly wastes energy (household gas is completely unnecessary for large flames, and incompletely burned gas is harmful to the human body); fourth, the high-pressure valve has high pressure and fast flow rate, and it is very likely that the ignition will not be able to release the liquefied gas into the air. It is easy to ignite the mixed gas and cause an explosion if it is ignited again. In severe cases, it will indirectly cause the explosion of the liquefied gas cylinder.
Everyone must pay attention that the pressure reducing valve for household gas stoves must be a regular one with the mark JYT-0.6, inlet pressure ≤1.56Mpa, outlet pressure 2800pa±500pa and non-adjustable pressure reducing valve.
There are many kinds of pressure reducing valves on the market with varying quality. Therefore, we must be cautious when buying pressure reducing valves, and we must buy qualified pressure reducing valves from regular manufacturers to prevent being deceived and buying counterfeit and inferior products.
