The pressure reducer is the most important element when using LPG equipment. The device ensures the operability of the entire system. It is necessary to reduce the pressure of the gas to the working pressure at the outlet of the cylinder, as well as to maintain the stability of the system, regardless of changes occurring in the tank.
If you do not install a pressure reducer, then a locking effect may occur, in which the gas flow will reach a critical point, and its outflow speed will be equal to the speed of sound. When the force actually reaches this value, the balloon will begin to jump in different directions like a balloon.
There are several types of devices installed on gas containers.
So, the air pressure reducer is used in enterprises to reduce and maintain a constant load in communications. Also, this device is used by scuba divers to reduce air pressure.
The oxygen reducer is indispensable in construction for gas cutting andwelding. It is actively used in the medical industry. Propane pressure reducer is used in metallurgy and mechanical engineering, in construction, to create conditions for autogenous work, as well as in everyday life. The device allows you to create a given pressure and adjust it.
Acetylene reducer is often used in utilities to cut pipelines and provide welding.
Devices allow you to work with any kind of gases. For hydrogen, combustible methane and other gases, devices with a left-hand thread are used. This is done specifically to prevent accidental connection of the device to the oxygen cylinder. Editors designed to work with non-flammable gases, helium, nitrogen and others have a right-hand thread. In addition, to avoid confusion, devices are painted in different colors.
According to the principle of operation, direct and reverse action gearboxes are distinguished. In the latter case, with a decrease in gas pressure in the cylinder, in working condition it rises. These devices are considered more convenient to use. By using a direct acting high pressure reducer, there is a decrease in the working state with a decrease in gas pressure.
When installing the fixture, carefully follow the instructions and precautions, as an accident may occur during start-up, and the system may explode.
It is necessary to install the gearbox after mounting the mechanical filter. Consideration should also be given to the possibility of future filter maintenance and cartridge replacement. When twisting the device, it is necessary to take into account the direction of flow, which is indicated by an arrow on the cylinder body. In addition, shut-off valves must be used for maintenance.
Gearboxes are made under pressure from high quality materials, aluminum alloys, bronze, stainless steel or plastic.
