Installation and commissioning of natural gas pressure regulating metering cabinet
Installation and commissioning of natural gas pressure regulating metering station Natural gas pressure regulating metering station is also called gas pressure regulating metering station Natural gas pressure regulating metering station Gas pressure regulating metering station Gas pressure regulating station is the key equipment of gas transportation pipeline, the first of natural gas pressure regulating and measuring station The role is to regulate and stabilize the system pressure, and to control the gas flow of the gas transmission system, the maintenance system to avoid excessive or too low outlet pressure. According to different levels of pressure level, pressure regulation accuracy, subordinate equipment, etc., there are building pressure regulating station, regional pressure regulating station, high pressure regulating station, city gate station, ultra high pressure regulating station; use US FISHER pressure regulating It is used as the main regulator of the pressure regulating metering station, such as the Italian TATANINI regulator. The regulator has a stable function and a wide range of voltage regulation, with and without blocking. Some regulators have filter maintenance for monitoring and safety. The layout of the pressure regulating metering station: 1+1, 2+0, 2+1 3+13+0, the internal valves are all imported, including pressure gauges, differential pressure gauges, filters, safety valves, etc. Together, we can also equip the equipment in the pressure regulating station according to your needs to satisfy your practical pressure regulation requirements and economical cost performance.

installation
The pressure regulating and metering station device is simple. It is only necessary to fix the pressure regulating metering station on the base and fix it with anchor bolts. Connect the inlet and outlet flanges to the gas pipe network and carry out static grounding. It should be noted that the flange device is not forced. Bit. The upper and lower flanges shall be parallel to the device. Before the pressure regulating station device is installed, the external piping shall be purged and subjected to pressure test and air tightness test. If the pressure regulating metering station and the pipeline are completed together, all the valves on the equipment should be closed during the pressure test of the pipeline (the pressure regulating metering station has passed the qualified test before leaving the factory). Otherwise it can cause damage to the pressure regulating metering station. The pressure regulating station can be activated only after the pipeline cleaning and pressure tests are passed.
debugging
Investigate the pressure values ​​shown on the pressure gauge. If the pressure is required to be adjusted, the adjusting screw can be rotated by a screwdriver, the clockwise rotation is the boosting, and the counterclockwise rotation is the pressure reducing, so that the outlet pressure is satisfactory. If the required pressure value and the original set value are relatively large, the conditioning spring should be exchanged. According to the unevenness of the outlet pressure, the spring with different wire diameters should be selected and debugged from the beginning. Do not use excessive force to lower the conditioning screw, otherwise it will cause deformation of the spring or damage to the film. In the case that the pipeline pressure is too high or too low, the regulator will actively intercept, and the regulator can be restarted after the pipeline pressure is normal. Regulator reset method: Pull the reset switch outward.
