Pressure reducer: application and characteristics

The pressure reducer is the most important element when using gas-cylinder equipment. The device ensures the operability of the entire system. It is necessary to reduce the gas pressure to the working pressure at the exit of the cylinder, and also to maintain the stability of the system, regardless of the changes occurring in the vessel.

If the pressure reducer is not installed, then the locking effect can occur, at which the gas flow reaches the critical line, and its exhaust velocity becomes equal to the speed of sound. When the force actually reaches such a value, the balloon will start, like a balloon, jump in different directions.

There are several types of devices installed on gas tanks.

For example , an air pressure reducer is used at enterprises to reduce and maintain a constant amount of load in communications. This device is also used by scuba divers to reduce air pressure.

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 machine building, in construction, to create conditions for performing autogenous works, as well as in everyday life. The device allows you to create a preset pressure and adjust it.

The acetylene reducer is often used in utilities for cutting pipelines and providing welding work.

Adaptations allow working with any kinds 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 thread. In addition, to avoid confusion, the devices are painted in different colors.

The operating principle distinguishes between direct and reverse action reducers. In the latter case, when the pressure of the gas decreases in the cylinder, in the operating state it rises. These devices are considered more convenient for operation. Using a high-pressure direct-acting pressure reducer, the operating state decreases with decreasing gas head.

When installing the device, you must carefully observe the instructions and precautionary measures, since an accident may occur during start-up and the system may explode.

Install the gear unit after installing the mechanical cleaning filter. Also, there should be a possibility of future maintenance of filters and replacement of cartridges. When tightening the device, it is necessary to take into account the flow direction indicated by the arrow on the cylinder casing. In addition, for maintenance purposes, shut-off valves must be used.

Reducers are manufactured under pressure from high quality materials, aluminum alloys, bronze, stainless steel or plastic.
