Vortex heating pressure adjuster

Abstract

The invention discloses a vortex heating pressure adjuster, and relates to the technical field of natural gas pipe networks. The vortex heating pressure adjuster comprises a main adjusting part, a commander and a heater; the heater comprises a heater body; the heater body is provided with an intake cavity, a heating cavity and a heat exchange cavity; the intake cavity is provided with an intake port; the intake port communicates with an inlet end of a gas pipe network through a pipe; the intake cavity is provided with an exhaust port; the exhaust port communicates with a downstream pipe of thegas pipe network; a heat exchange cavity is formed between a shell of the heater body and the heating cavity; the shell of the heater body is provided with a heat exchange intake port and a heat exchange exhaust port; the heat exchange intake port communicates with the inlet end of the gas pipe network; and the heat exchange exhaust port is connected with the commander. The vortex heating pressure adjuster uses heat, generated by high-pressure gas in an inlet of the gas pipe network, for heating, and is simple in installation, low in energy consumption, free of external heating source, simplein heater manufacturing and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline network, in particular to a vortex heating type pressure regulator. Background technique [0002] In the gas pressure regulating skid, because the pressure difference between the front and rear of the gas is too large or the ambient temperature is too low, the gas temperature will be too low, and the gas contains moisture, which will cause ice blockage in the gas pipeline and affect the gas supply, so a heater is required. Increase gas temperature. The heaters on the market include: electric heaters, water bath heaters, etc., all of which require an external heating source. The principle of this type of heater is: after the medium to be heated enters the heater, it flows in the annular space with the electric heating source for a certain period of time. Then flow out to achieve the purpose of raising the temperature. [0003] On June 18, 2014, the State Intellectual Property Office ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects and deficiencies in the above-mentioned prior art, the present invention provides a vortex heating type pressure regulator, which is mainly used for heating the air intake of the pilot of the pressure regulator, preventing the pilot from being blocked by ice, preventing the The gas pressure regulator stops working, which affects the gas supply. The purpose of the invention is to solve the problem of the inlet heating of the pilot in the gas pressure regulator in the prior art. The vortex heating type pressure regulator of the invention uses the gas pipe network to import high-pressure gas Generates heat for heating, simple installation, low energy consumption, no external heating source, simple heater manufacturing, and low manufacturing cost
