Description

Technical Field

[0001] The utility model belongs to the technical field of gas pressure regulating cabinets, in particular to an auxiliary thermal insulation device for a gas pressure regulating box. Background Art

[0002] The pressure regulating equipment is a very important equipment in the gas transmission and distribution link. By adjusting the valve opening inside the pressure regulator, the flow of gas through the valve is controlled, thereby achieving the regulation of the gas supply pressure.

[0003] At present, the temperature of natural gas at the outlet of the pressure regulator will generally drop sharply. In the cold winter, the climate is even lower and the temperature drops more. Because the pressure pipe and valve port of the natural gas pressure regulator are relatively small, if the natural gas contains moisture or impurities during transportation, it is very likely that the pressure pipe or valve of the pressure regulator will be frozen, which will affect the safe transportation and stable supply of natural gas.

[0004] Therefore, based on the above problems, we designed a gas pressure regulating box auxiliary thermal insulation device. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an auxiliary thermal insulation device for a gas pressure regulating box, which solves the technical problem that the existing gas pressure regulating equipment is not equipped with a thermal insulation system, and because the pressure-taking pipe and valve port of the natural gas pressure regulator are relatively small in diameter, if the natural gas is transported with moisture or impurities, it is very likely that the pressure-taking pipe or valve of the pressure regulator will be frozen, which affects the safe transportation and stable gas supply of the natural gas.

[0006] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the utility model, a gas pressure regulating box auxiliary heat insulation device is provided, comprising a pressure regulating box body and a box door arranged on the side of the pressure regulating box body;

[0007] Also includes:

[0008] A heat insulation component, the heat insulation component includes an electric heating heating belt, a time control switch arranged in a voltage regulating box, and a microcomputer intelligent temperature controller connected to the time control switch;

[0009] Wherein, the electric heating tape is connected to the microcomputer intelligent thermostat, and the time control switch is connected to the electric heating tape.

[0010] A further improvement is that an observation window is provided on the box door, and tempered glass is provided in the observation window.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model installs an electric heating and heat preservation system on the gas equipment, so that the electric heating heat preservation belt is energized to generate heat and dissipate heat, thereby compensating for the heat loss of the pipeline gas during use or increasing the local temperature of the pipeline gas pipeline. Through the electric heating and heat preservation system, the time-controlled switch microcomputer intelligent thermostat controls the switching time and operating temperature of the electric heating heat preservation belt, effectively reducing the heat loss caused by the pressure-taking pipeline of the voltage regulator and the pressure reduction of the voltage regulator, effectively improving the normal operation of the gas equipment during low-temperature freezing weather, and ensuring a stable gas supply.

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, the gas pressure regulating box auxiliary heat insulation device comprises a pressure regulating box body 4 and a box door 41 arranged on the side of the pressure regulating box body 4;

[0022] like Figure 1 and Figure 2 As shown, when implemented, it includes: a heat insulation component, the heat insulation component includes an electric heating heating belt 1, a time control switch 2 set in a voltage regulating box 4, and a microcomputer intelligent temperature controller 3 connected to the time control switch 2;

[0023] Among them, the electric heating tape 1 is connected to the microcomputer intelligent temperature controller 3, and the time control switch 2 is connected to the electric heating tape 1.

[0024] In this embodiment, an observation window 411 is further provided on the box door 41, and tempered glass is provided in the observation window 411 for observing the operating status of the time control switch 2 and the microcomputer intelligent temperature controller 3;

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, a circuit breaker is additionally arranged in the regulating box 4, connected to the control circuit of the time switch 2, the electric heating tape 1 and the microcomputer intelligent temperature controller 3, for cutting off the power supply after an abnormality occurs.

[0026] During the implementation of this embodiment, it should also be noted that the time-controlled switch 2, electric heating cable 1, microcomputer intelligent temperature controller 3 and the circuit breaker mentioned above in the application document are all commercially available products of the prior art, and their working principles have been disclosed. Before the implementation of this application, the corresponding model is selected for installation, debugging and use.

[0027] In addition, it should be noted that the application document has the following disadvantages: the existing gas pressure regulating equipment is not equipped with a thermal insulation system, and the pressure pipe and valve port of the natural gas pressure regulator are relatively small. If the natural gas is transported with moisture or impurities, it is very likely that the pressure pipe or valve of the pressure regulator will be frozen, which will affect the safe transportation and stable gas supply of natural gas. Therefore, the auxiliary thermal insulation device of the gas pressure regulating box is designed, and no improvements in other aspects are involved;

[0028] The working principle of the auxiliary thermal insulation device of the gas pressure regulating box is introduced as follows:

[0029] During installation, the on-site installer first wraps the electric heating cable 1 around the gas pipeline that needs to be compensated, and then assembles and debugs each equipment component;

[0030] When in use, by installing an electric heating and insulation system on the gas equipment, the electric heating tape 1 is powered on to generate heat and dissipate heat, thereby compensating for the heat loss of the pipeline gas during use or increasing the local temperature of the pipeline gas pipeline. Through the electric heating and insulation system, the time switch 2 and the microcomputer intelligent thermostat 3 control the switching time and operating temperature of the electric heating tape 1, effectively reducing the heat loss caused by the pressure-taking pipeline of the voltage regulator and the pressure reduction of the voltage regulator, effectively improving the normal operation of the gas equipment during low-temperature freezing weather, and ensuring a stable gas supply.

[0031] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
