Abstract

The invention relates to a gas pressure regulator anti-surge device and belongs to the technical field of gas transmission and distribution systems. The device comprises a first damper and a second damper. The first damper is arranged transversely, the gas inlet end of the first damper communicates with an impulse pipe communicating with a gas outlet pipeline, and the gas outlet end of the first damper communicates with a gas outlet pipeline communicating with a lower cavity; and the second damper is mounted in a breathing port of an upper cavity and of a structure consistent with that of the first damper, the second damper is arranged vertically, and the upper end of the second damper communicates with the external atmosphere. By controlling the ventilation flow rates of the first damper and the second damper, the gas flow speeds of the upper cavity and the lower cavity are regulated and controlled, resonance between the upper cavity & the lower cavity and a valve port is disrupted, accordingly, the pressure stabilizing precision of a pressure regulator is improved, and a surge phenomenon of the gas pressure regulator can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of gas transmission and distribution systems, in particular to an anti-surge device for a gas pressure regulator. Background technique [0002] The gas pressure regulator is the key equipment in the gas transmission and distribution system, which is suitable for occasions where the gas needs to be adjusted and stabilized. The main function of the pressure regulator is to automatically adjust the gas outlet pressure to stabilize it in a certain pressure range to meet the needs of customers. [0003] During the operation of the transmission and distribution system, the pressure downstream of the pressure regulator is not constant, nor does it change smoothly, and there will be fluctuations. The fluctuating pressure felt by the main diaphragm will cause the valve port to increase or decrease continuously, thus causing non-stop surge phenomenon. In response to the surge problem, the following measures are gene...
