Methane pressure reducer YQJW-04 brass explosion-proofThe function is to maintain a stable pressure of gas during use, thereby ensuring a stable fuel to air ratio (the ratio of gas to air) for gas appliances; The use of pressure reducing valves in gas supply systems reduces and stabilizes gas pressure at an appropriate level that enables safe, economical, and efficient utilization of gas.
Single pressure reducing structure
When installing a methane pressure reducer, caution and proper operation are required. The specific installation requirements are as follows:
1. The installation of methane pressure reducers requires pressure testing and purging of pipelines to ensure their sealing and cleanliness.
2. The methane pressure reducing valve should be installed horizontally and vertically on the pipeline, and attention should be paid to ensuring that the flow direction of the medium in the pipeline is consistent with the direction of the arrow shown on the valve body during installation.
3. Control ball valves should be installed on both sides of the methane pressure reducing valve, and a bypass pipe should be installed for maintenance.
4. Pressure gauges should be installed on both the high and low pressure pipelines of the methane pressure reducing valve for easy regulation, and the pressure changes behind the valve can be observed during operation.
5. Install a safety relief valve on the pipeline to protect the reliability and safety of the methane pressure reducing valve operation.
6. Indoor gas pipelines should be equipped with gas leakage alarm devices indoors to ensure timely alarm and elimination of gas leakage hazards.

Main advantages:Methane pressure reducer YQJW-04 brass explosion-proofMade of brass, with precise adjustment, accurate reading, and resistance to pressure and explosion. 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, the pressure regulator screw should be loosened first, then the gas cylinder valve should be closed, and the gas inside the pressure regulator should be slowly released to protect the spring and pressure relief valve from damage. After the work is completed, the pressure regulator should be removed from the gas cylinder and stored properly.

The pressure reducing valve 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.
