Gas regulating devices and pressure regulating boxes are mainly terminal pressure regulating equipment that should be used in the medium and low pressure gas transmission and distribution pipeline network. It can supply gas for residential quarters, public service users, gas boilers, industrial furnaces, direct-fired equipment, etc.

Performance characteristics of gas regulator

1. Standard structure

2. Applicable medium: natural gas, coal gas, liquefied petroleum gas and other gas

3. Integrated control: pressure regulation, metering, filtering, emergency cut-off, and safety relief in one integration 4. Equipped with overpressure protection device, emergency cut-off system, and safety relief device

5. The pressure regulating branch adopts 100% flow design. It can switch the air supply between the main and the auxiliary circuit to ensure uninterrupted air supply. 6. Reasonable structure and perfect functions. The system has strong coordination and a manual control valve in the bypass.

7. Good scalability, gas alarm, remote measurement and remote control functions can be added according to user requirements; data collection, heat preservation and temperature increase functions 8. Integrated design, compact structure, easy installation and debugging

9. The outer box adopts steel plate sprayed box body, stainless steel box body, color steel insulation box body, which can meet the different environmental requirements of customers

Precautions for installation, operation and use of gas regulator:

1. When storing, transporting, installing, checking and accepting, using, and overhauling the gas pressure regulator box, it must strictly implement the national standards and comply with the company's regulations.

2. The gas pressure regulator box and its components should be stored in a dry, ventilated, and non-corrosive room.

3. During the transportation of the gas surge tank, it should be protected from severe vibration and rain, and it is strictly forbidden to throw, collide, etc.

4. When installing the gas pressure regulator box, the flange of the riser pipe should be parallel to the center distance of the flange of the inlet and outlet ball valve. It is strictly forbidden to use a crowbar to force the combination when the difference is too large, which will cause the pipeline to deform too much, and the interface seal will be damaged and air leakage. The flange of the ball valve should be screwed until the boss is exposed, which can compress the flange gasket. It is strictly forbidden to weld with a voltage regulator to prevent the film from being damaged by the high temperature of the electric welding.

5. Before installing the gas pressure regulator, clean the pipes as required to prevent oxides, sand and debris in the pipes from blocking the valve ports.

6. When the gas pressure regulator box is installed for pipeline pressure test, the regulator must be blocked with a blind plate, and the ball valve must be closed, especially on the downstream outlet side, otherwise the regulator will be easily damaged.
