Type of Gas Regulator RTZ-25 Runfeng Provision
If the opening degree of the regulator is between 70% and 90%, it can not only make the regulator work in good condition, but also ensure the normal operation of downstream residents'pressure during peak gas use. If the position of the regulator has been fixed by the developer, it can only be installed in a corner of the residential area, the distance regulator should be considered when selecting the regulator. The pressure in front of the remote user stove is not less than 1000Pa, so the voltage regulator should be one size larger than the normal one when choosing. In the same area, we should also consider the future development scale of the district, and have a certain surplus in the selection of the voltage regulator. Otherwise, the flow of the voltage regulator will not be able to meet the peak of downstream users if the users of the district increase. The amount of air used.
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.
