Natural gas pipe temperature regulation system with automatic temperature control functional module

Abstract

The invention discloses a natural gas pipe temperature regulation system with an automatic temperature control functional module. The natural gas pipe temperature regulation system with the automatic temperature control functional module comprises an automatic temperature control unit and a pipeline equipment adjustment unit. The automatic temperature control unit is composed of a temperature sensing probe, a temperature exchanger, insulation push-pull rods and a valve executive mechanism. The temperature sensing probe is fixedly arranged on the inner wall of the middle portion of a pipe and matched with the temperature exchanger to play a role. The insulation push-pull rods are arranged on one side of the inner wall of the pipe and are in movable connection by pushing and pulling a corresponding snap structure. Compared with the prior art, the natural gas pipe temperature regulation system with the automatic temperature control functional module is simple in structure, easy to operate, low in failure rate and high in efficiency. The automatic temperature control unit improves the system temperature control accuracy. A check valve and a control valve are arranged for preventing temperature sensing gas or liquid from escaping. Therefore, the equipment operation safety is improved, the equipment maintenance and repair is facilitated, and the scope of temperature application of heated or cooled natural gas in the pipe is widened. The natural gas pipe temperature regulation system with the automatic temperature control functional module is especially suitable for northern cold regions and southern humid and rainy regions.

Description

technical field [0001] The invention relates to the technical field of automatic pipeline fluid temperature control systems with automatic heating and cooling functions, in particular to a natural gas pipeline temperature adjustment system with automatic temperature control function modules. Background technique [0002] At present, when natural gas is unloaded, the pipe drawn from the expansion valve needs to be heated to prevent the formation of hydrates such as condensation, freezing and scale. At the same time, because there is no automatic temperature control device such as a stable sensor, people need to unload while heating and pay attention to temperature changes during operation, which not only wastes time and energy, but also increases costs. [0003] In order to solve the above problems well, the present invention provides a natural gas pipeline temperature adjustment system with an automatic temperature control function module. SUMMARY OF THE INVENTION [0004...

AI Technical Summary

Problems solved by technology

[0002] At present, when natural gas is unloaded, in order to prevent the formation of hydrates such as condensation, freezing and scale, the pipes drawn from the expansion valve need to be heated. Heat, and the need for heat is getting higher and higher. At the same time, because there is no automatic temperature control device such as a stable sensor, people need to heat while unloading and pay attention to temperature changes when operating, which wastes time and energy and increases costs.
