Abstract

The invention discloses a natural gas pressure regulator pressure leading device and a pressure regulating method. The natural gas pressure regulator pressure leading device comprises a heat pipe type vortex tube, a flow control valve, a gas mixing chamber, a flow regulating valve and a temperature detection device, a high-pressure gas inlet of the heat pipe type vortex tube is connected with a natural gas main pipeline behind a pressure regulator, hot-end natural gas of the vortex tube flows in the gas mixing chamber through the flow control valve, cold-end natural gas is directly injected into a natural gas pipeline, the flow regulating valve and the temperature detection device are used for automatic regulation and control, the temperature of natural gas entering a pressure regulator regulating module is ensured to be stable, and abnormal closing of the pressure regulator due to over-low or over-high temperature is prevented.

Description

technical field [0001] The invention belongs to the technical field of natural gas transmission and distribution, and in particular relates to a pressure introduction device and a pressure regulation method of a natural gas pressure regulator. Background technique [0002] At present, in the pressure regulator device of the gas transmission and distribution system, the ice blockage of the pressure regulator is caused by the low temperature of the natural gas after pressure regulation, resulting in system failure. At present, the common way is to install an electric heating device on the sampling pipe of the pressure regulator. [0003] This device can effectively solve the problem of ice blockage of the voltage regulator to a certain extent, but its disadvantages are that the heating cable needs external power supply, the service life is short, and the installation is not beautiful enough. Contents of the invention [0004] In order to solve the above technical problems, t...
