Problems solved by technology
If the temperature is too low, the film will be "frozen"; if the temperature is too high, the film will be easily fatigued and the service life will be reduced
[0003] To solve the influence of air temperature on the working state of the pressure regulating valve, the methods currently in use are mainly two methods: circulating water heat tracing and electric heating heat tracing. The former has a two-way temperature adjustment function, and the latter is only suitable for winter
The common defect of the two methods is that the investment cost is high, and there are even certain safety hazards. For example, the circulating water system needs circulating water source and circulating power source, and the electric heating system will have potential safety hazards caused by electric leakage.

The invention discloses a geothermy pipeline heating device for a pressure regulating valve. The geothermy pipeline heating device comprises a pipeline heating kettle body, circulating pipes and a heat insulation box, and is characterized in that the pipeline heating kettle body is an integrated or split closed container and provided with an inlet pipe and an outlet pipe, wherein at least one circulating pipe is arranged in the pipeline heating kettle body in the vertical direction; the circulating pipes are assembled and connected with the pipeline heating kettle body through supports; the lower half part of the pipeline heating kettle body is buried in the surface of soil; the heat insulation box is assembled above the pipeline heating kettle body; the pipeline heating kettle body is made of a metal with favorable heat-conducting property; the circulating pipes are straight through pipes; and an emptying pipe is arranged at the top of the heat insulation box. The geothermy pipeline heating device is scientific and reasonable in structure, convenient to construct, low in investment, excellent in heating effect and therefore worthy of popularization.
Description
technical field [0001] The invention relates to the technical field of gas transmission and distribution, in particular to a geothermal pipeline heat tracing device for a pressure regulating valve. Background technique [0002] Most of the gas pressure regulating valve adopts self-operated structure. Its working principle is to automatically control the size of the valve switch by acting on the spring force above the membrane of the core component and the gas lift at the lower part to maintain a relatively stable transmission and distribution pressure. . The normal working temperature of the film is -10°C ~ 60°C, if the temperature is too low in winter or too high in summer, it will affect the working state of the film. If the temperature is too low, the film will be "frozen"; if the temperature is too high, the film will be easily fatigued and the service life will be reduced. [0003] To solve the influence of air temperature on the working state of the pressure regulati...
