Oxygen pressure reducer YQY-08 typeIt is a specialized device that automatically reduces the working pressure of pipelines. Y uses the opening of the opening and closing parts in the control valve body to adjust the flow rate of the medium, reducing the pressure of the medium. At the same time, it uses the pressure behind the valve to adjust the opening of the opening and closing parts, keeping the pressure behind the valve within a certain range. The characteristic of the pressure reducer is to maintain the outlet pressure value within a certain range when the inlet pressure is constantly changing.
Air pressure reducer is a gas cylinder pressure reducing device that can adjust the high-pressure gas inside the cylinder to a practical pressure for use. It is mainly used in welding, cutting, chemical, pharmaceutical and health, electronic industries, and other fields.Oxygen pressure reducer YQY-08 typeRegardless of changes in input pressure and output flow rate, stable output pressure can be ensured.
The use of pressure reducers should be carried out according to the following rules:
(1) The action of releasing gas from the gas cylinder or opening the pressure reducer must be slow. If the valve opening speed is too fast, the temperature of the gas in the working part of the pressure reducer will greatly increase due to adiabatic compression, which may cause organic materials such as rubber packing and rubber film fiber pads to catch fire and burn out, and may also cause the pressure reducer to burn out. In addition, static sparks generated by rapid deflation and oil stains on the pressure regulator can also cause ignition, burning, and damage to the pressure regulator components.
(2) Precautions before installing the pressure regulator and when opening the gas cylinder valve: Before installing the pressure regulator, slightly open the oxygen cylinder valve to blow away dirt to prevent dust and moisture from entering the pressure regulator. When opening the gas cylinder valve, the outlet of the valve should not be aimed at the operator or others to prevent high-pressure gas from suddenly rushing out and injuring people. The joint between the outlet of the pressure reducer and the gas rubber pipe must be tightened with a wire or clamp that has been overheated; Prevent the risk of detachment after air supply.
(3) Precautions for loading, unloading, and operation of pressure reducers: When loading and unloading pressure reducers, attention must be paid to preventing the thread of the pipe joint from slipping, in order to avoid improper rotation and injection. During the work process, it is necessary to pay attention to observing the pressure value on the work pressure gauge. When stopping work, first loosen the pressure regulating screw of the pressure reducer, then close the oxygen cylinder valve, and slowly exhaust the gas inside the pressure reducer. This can protect the spring and pressure reducing valve from damage. After the work is completed, the pressure regulator should be removed from the gas cylinder and stored properly.
(4) The pressure regulator must be regularly calibrated, and the pressure gauge must be inspected regularly. This is done to ensure the reliability of pressure regulation and the accuracy of pressure gauge readings. If any air leakage or malfunction of the pressure gauge needle is found during use, it should be repaired in a timely manner.
(5) Handling of pressure regulator freezing. If the pressure regulator freezes during use, use hot water or steam to thaw it, and never use flames or red iron to bake it. After the pressure regulator is heated, any residual moisture must be blown off.
(6) The pressure regulator must be kept clean. The pressure reducer must not be contaminated with grease or dirt. If there is grease, it must be wiped clean before use.
(7) Pressure reducers and gauges for various gases must not be interchanged, such as pressure reducers for oxygen, which cannot be used in systems such as acetylene and petroleum gas.
