The advantage and disadvantage of Jinan gas pressure regulator RX200 comparing with building boxes: advantages and disadvantages of regional pressure regulation and building pressure regulation
1. Regional pressure regulation technology is that after the city medium pressure gas pipeline enters the regional pressure regulation station (room), after the pressure is adjusted to the user's need pressure, it is transported to the user through the low pressure pipeline network.
1.1 Advantages of Regional Voltage Regulation:
1.1_1 gas supply capacity, easy to centralized management and maintenance;
1.1.2 The distance of medium pressure gas pipeline is shorter and the operation risk is reduced.
1.2 Disadvantages of Regional Pressure Regulation:
1.2.1 The site selection requirement of surge station is high, which not only meets the requirement of safe distance between other buildings and structures, but also locates in the center of gas load or close to large users. In the current situation of urban land with inches of land and inches of gold, site selection is more difficult.
1.2.2 The middle and low pressure gas pipelines may be parallel for a long distance, and the diameter of the low pressure gas pipeline network is large.
Not only takes up more underground resources, but also the pipeline is very difficult.
1.2.3 The construction cost of surge station (room) is higher.
1.2.4 The gas supply range is large, so the pressure of each gas point is unstable, and it is easy to overpressure or underpressure.
1.2.5 Pipeline network and pressure regulating facilities have a larger impact on customers during maintenance.
2. The technology of building surge tank is that the city medium pressure gas pipeline enters the building surge tank directly after entering the courtyard. According to the actual situation of users, the building surge tank can set up a surge tank for a single building or several buildings. After the pressure is adjusted to the user's need, it is transported to the user through the low-pressure pipeline network in front of the building.
Advantages of 2.1 Building Voltage Regulation:
2.1.1 The diameter of the medium pressure pipeline network is small but the gas transmission capacity is large.
2.1.2 The safety distance between the surge tank of the building and the building is small and the site selection is easy.
2.2.3 Small size, low cost, convenient and fast installation;
2.1.4 The gas supply range is small, the gas supply is stable and the combustion condition is good.
2.1.5 The range of customers affected by the maintenance of voltage regulating facilities is small.
Defects of 2.2 Floor Pressure Regulation:
2.2.1 With the continuous expansion of urban gas supply scale, the operation, maintenance and maintenance of surge tank are increasing day by day, which requires a lot of manpower, material and financial investment.
2.2.2 The long distance of medium pressure gas pipeline and the scattered setting of pressure regulating box increase the risk of operation and management.
2.2.3 Long-term exposure to wind and sunshine can not be maintained in time to the surrounding environment brings a sense of obstruction.
