Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, in particular to a natural gas protective pressure regulating box. Background Art

[0002] The natural gas pressure regulating box is a key equipment in the gas transmission pipeline. Its main function is to regulate and stabilize the system pressure, control the gas flow of the gas transmission system, and protect the system from excessively high or low outlet pressure. According to different functions such as pressure level, pressure regulating accuracy, and auxiliary configuration, there are building pressure regulating boxes, regional pressure regulating boxes, high-pressure pressure regulating stations, city gate stations, and ultra-high-pressure pressure regulating stations.

[0003] When choosing a natural gas pressure regulating box, you need to consider different functions such as pressure level, pressure regulating accuracy, auxiliary configuration, as well as gas quality, use environment and other factors to ensure the normal gas supply of the pressure regulating system.

[0004] Since water vapor in natural gas may form condensed water when the temperature is too low, ice may form at the main regulating valve port of the pressure regulator under low temperature conditions, which may cause the pressure regulating function of the pressure regulator to fail, posing a hidden danger to gas safety and normal gas use by users. Therefore, it is necessary to cover the natural gas pressure regulating box with a glass fiber insulation layer to prevent such phenomenon. Although this method can play a certain protective role, its effect is not high and it is also time-consuming and labor-intensive. In order to improve the situation that the pressure regulating box may malfunction when the external temperature changes greatly, a natural gas protective pressure regulating box is proposed.

[0014] Compared with the prior art, the utility model provides a natural gas protection pressure regulating box, which has the following

[0015] Beneficial effects:

[0016] 1. The natural gas protective pressure regulating box is constructed by sending the natural gas pipeline from the through hole through the auxiliary pipe into the interior of the box. After the natural gas pipeline and pressure gauge, differential pressure gauge, filter, safety valve and other equipment are installed, the insulation horizontal plate is inserted into the inner bottom wall and inner top wall of the box along the I-shaped rod, and the insulation vertical plate is embedded into the interior of the box along the auxiliary rod and the side wall of the box.
