Influence of long distance pipeline on gas regulator (Run Feng)
Influence of impurities in 1 natural gas pipeline
Impurities will affect the closing performance of the regulator to a certain extent. The diameter of the nozzle in the regulator is generally very small and easy to plug, resulting in failure of the regulator. Figure 4 shows a large number of oily impurities in the valve orifice and valve pad of Caobao Road station regulator. Due to the influence of impurities on the valve port, the performance of the regulator is worse. The outlet pressure and overpressure are cut off when the gas is depressed.
The effect of the 2 voltage regulator itself
The pressure regulator may cause damage or rupture of the pressure regulating film during operation, the swelling of the valve cushion and the friction of the valve pad, and the regulation of pressure or cutting off.
Spring fatigue, pressure and pressure; signal pressure pipe blockage; valve stem action is not flexible, card; cut off the contact friction force these will lead to the pressure regulator work instability, the stability of the pressure difference, work failure, and even lead to the pressure regulator cut off.
3 countermeasures and measures
(1) install effective filtration devices before the regulator and conduct regular drainage. In addition, regular cleaning of the filter before the regulator can ensure that there is no impurity in the piping of the regulator system.
(2) maintain the regulator regularly according to the requirements of the regulator maintenance. Clean the internal parts of the voltage regulator regularly, and
Damage or wear overrun parts found during maintenance, and carry out in time.
Change to ensure that the voltage regulator is in normal working condition.
