A pressure reducer is an essential element when using gas equipment. The device ensures the performance of the entire system. It is necessary to reduce the gas pressure to the working one at the outlet of the container, as well as to maintain the stability of the system, regardless of changes in the tank.
If you do not install a pressure reducer, then a locking effect may occur, at which the gas flow reaches a critical point, and its flow rate will be equal to the speed of sound. When the force actually reaches such a value, the balloon will begin, like a balloon, to jump in different directions.
There are several types of devices installed on gas tanks.
So, an air pressure reducer is used at enterprises to reduce and maintain a constant load in communications. Also, this device is used by scuba divers to reduce air pressure.
An oxygen reducer is indispensable in construction for gas cutting and welding. It is actively used in the medical industry. Propane pressure reducer is used in metallurgy and mechanical engineering, in construction, to create conditions when performing autogenous work, as well as in everyday life. The device allows you to create a given pressure and make its adjustment.
An acetylene reducer is often used in public utilities for cutting pipelines and for welding.
Devices allow you to work with any kind of gas. For hydrogen, combustible methane and other gases, devices with left-hand threads are used. This is done specifically to prevent accidental connection of the device to an oxygen cylinder. Editors designed to work with non-combustible gases, helium, nitrogen and others have a right-hand thread. In addition, to avoid confusion, the devices are painted in different colors.
According to the principle of operation, gearboxes of direct and reverse action are distinguished. In the latter case, when the gas pressure decreases in the cylinder, in the working state it rises. These devices are considered more convenient for operation. Using a direct pressure high pressure reducer, a decrease in the operating state occurs with a decrease in gas pressure.
When installing the device, the instructions and safety precautions must be carefully observed, since during startup an accident can occur and the system can explode.
It is necessary to install the gearbox after mounting the mechanical cleaning filter. Consideration should also be given to 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 the arrow on the container 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.
