(l) Station pressure regulating device Station pressure regulating device refers to the pressure regulating system of gas source, gate station, storage and distribution station, gas distribution station, gasification station, gas distribution station, gas filling station, etc. It is designed and built according to the process requirements of the station and storage yard. Generally, the inlet and outlet pressure of pressure regulating devices such as stations are relatively high, which can be installed outdoors or indoors according to conditions and requirements; The pressure regulating device of the station is generally equipped with measuring equipment to measure the gas entering and leaving the station.

(2) Pipe network pressure regulating device The pipe network pressure regulating device refers to the pressure regulating system set by changing the pressure of pipe networks at all levels in the power transmission and distribution system. The inlet and outlet pressure is determined by the pressure level of the power transmission and distribution system. Network voltage regulators are usually located in dedicated buildings. Generally, there is no need to install metering equipment in the network voltage regulator. The network voltage regulator can be divided into grid connected voltage regulator and regional voltage regulator.

Pressure regulating device of pipe network Pressure regulating device of pipe network: when the pressure level of gas transmission and distribution system pipe network is level 3 or above, the outlet pressure of pressure regulating device is above medium pressure, and the pipe network is not directly related to a large number of users. Connected network voltage regulator.

The outlet pressure of the middle note pressure regulating device in the transmission and distribution system of the regional pressure regulating device is a low-pressure network pressure regulating device whose pipe network is directly connected to a large number of users. The regional pressure regulating device supplies gas to users in a certain area.

(3) China lpg reducer is a pressure regulating system that directly supplies gas to industrial users or large commercial users from the urban gas transmission and distribution system. The special voltage regulating device shall be designed with measuring equipment. According to the air inlet pressure and environmental conditions, it can be installed on the open air, single floor, single floor, single floor production workshop building adjacent to the gas building, the top floor and roof platform of the gas building. Special voltage regulating devices can also be installed in the voltage regulating cabinet or box in proportion.

(4) User voltage regulating device User voltage regulating device is a voltage regulating system used by one or more residential users. The pressure regulating device of a household is generally installed on the gas appliance, and the pressure of the intake pipe section is relatively high, which is laid indoors. Therefore, necessary safety measures shall be taken to ensure safe operation. The pressure regulating device for one (or more) residential users is generally installed in the yard or in a metal box hanging on the exterior wall of the building.
