Characteristic of Xianju rx160/0.4CRF for Natural Gas Pressure Regulator
Through the analysis of the maximum pressure drop of the natural gas processing system, when the pressure of the upstream natural gas pipeline network can meet the demand of gas turbine under various working conditions, the natural gas pressure regulating station should be selected for the natural gas processing system.
Gas surge station is generally divided into several functions according to the different functions of each device.
Typical natural gas surge stations include emergency cut-off pry at entrance, crude separation pry, metering pry, filter pry, heating pry, pressure regulating pry, condensate collection device, release device and control system.
The voltage regulator is selected according to the user. There are three types of gas users, one is resident users, one is commercial users, and the other is industrial users. They have great differences in the choice of regulators. They can not share a regulator. The gas pressure of commercial users and industrial users is usually higher.
The process of gas surge tank is that after the city medium pressure gas pipeline enters the gas surge station (room), it is transferred to the user through the low pressure pipeline network after the pressure is adjusted to the user's need.
1. Advantages of gas surge tank:
It has large gas supply capacity and is convenient for centralized management and maintenance.
The distance of medium pressure gas pipeline is short and the operation risk is reduced.
2. Disadvantages of gas pressure regulator:
Pressure surge station location requirements are high, not only to meet the safety distance requirements with other buildings and structures, but also to be located in the center of gas load or close to large users. In today's urban land inch by inch, location selection is more difficult.
Medium and low pressure gas pipelines may be parallel for a long distance, and the diameter of low pressure pipeline network is large.
Not only takes up more underground resources, but also the pipeline is very difficult.
The construction cost of surge station (room) is higher.
The gas supply range is large, so the pressure of each gas point is unstable, and it is prone to overpressure or underpressure.
Pipeline network and pressure regulating facilities have a large impact on customers when they are repaired.
