What constitutes the gas regulator RTZ-25 Runfeng provides complete equipment
Gas equipment belongs to high-risk industry. Every year, the national quality inspection department requires us to send all types of equipment to inspect. Every three years, 118 standards of special equipment license issuing units will be inspected at home, which need to meet all the standards. Every engineer must be responsible. Strength test is 24 hours before leaving the factory, air tightness test is 24 hours. Failure is not allowed to leave the factory. This is just a standard for a regular manufacturer.
[How to classify the natural gas pressure regulating equipment? ]
The origin of gas pressure regulating equipment is classified as domestic equipment and imported equipment. With the increase of gas consumption from West to East Gas Pipeline in China, the technology level of gas equipment in China has been steadily improved. In recent years, the technology and performance of most pressure regulating equipment can replace imported equipment. And the domestic voltage regulation equipment is in line with China's national conditions, more suitable for Chinese users.
When choosing voltage regulator, commercial users and industrial users generally choose double-circuit regulator. The import pressure range of commercial users is 0.2 MPa~0.4 MPa, the outlet pressure of regulator is 12 000 Pa~16 500 Pa, the import pressure range of industrial users is 0.2 MPa~0.4 MPa, and the outlet pressure of regulator is 20-50 KPa. They usually choose to be placed close to the user, which can reduce the pressure loss caused by distance.
The above is how to choose the regulator according to the different flow rate and users, but no matter what kind of regulator is chosen, the gas regulator cabinet must be equipped with filters, safety release valves, emergency shut-off valves, indicator pressure gauges and other related accessories, so that the regulator has emergency shut-off protection during the process of pressure regulation. With the function of automatic discharge protection under overpressure, the pressure regulating accuracy of the regulator must be controlled in the range of 25%-30%. Its filter device should be equipped with a differential pressure gauge, and the filtering accuracy must be controlled in the range of 200 microns. In addition, commercial and commercial users install pressure regulators to compensate for flow errors caused by large pressure difference.
