Description

Technical Field

[0001] This utility model relates to the field of natural gas technology, specifically to a heating device for a natural gas pressure regulating equipment. Background Technology

[0002] Natural gas pressure regulating equipment is a device used to reduce the pressure of natural gas. It is widely used in natural gas transmission and distribution systems. Its main function is to reduce high-pressure natural gas to a pressure that meets the usage requirements through the pressure regulator, so as to ensure the safe and stable transmission of natural gas.

[0003] Because the natural gas transported in the pipeline may experience a drop in temperature due to pressure reduction when passing through the regulating stage, the low gas temperature will lead to poor gas flow, increase pipeline resistance, and reduce flow rate. At the same time, if moisture in the natural gas cannot be effectively treated, it will condense into water and ice as the gas temperature drops, causing pipeline blockage and even potentially leading to valve and regulator failure, affecting the stability and safety of the system. Utility Model Content

[0004] The purpose of this utility model is to provide a heating device for a natural gas pressure regulating equipment, in order to solve the problem mentioned in the background art that the natural gas in the pipeline may experience a drop in temperature due to pressure reduction when passing through the regulating stage. As a result, the gas flow becomes poor due to the low gas temperature, which not only increases the resistance in the pipeline, but also causes the gas to condense into water and ice as the temperature drops, and may even lead to the failure of valves and regulators, affecting the stability and safety of the system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device for a natural gas pressure regulating equipment, comprising:

[0006] A pressure regulating cabinet, wherein a gas pressure regulator is fixedly installed inside the pressure regulating cabinet;

[0007] Also includes:

[0008] The installation compartment is fixedly installed on the side wall of the pressure regulating cabinet and is symmetrically arranged about the vertical central axis of the pressure regulating cabinet. A heater is fixedly installed inside the installation compartment, and the heaters are arranged in an array about the horizontal line of the installation compartment. Installation slots are fixedly installed on the top and inner top of the pressure regulating cabinet, and installation slots are also fixedly installed on both the left and right ends inside the pressure regulating cabinet. Insulation boards are slidably connected inside the installation slots, and the installation slots and insulation boards are fixedly connected together by bolts. A temperature detector is fixedly installed on the left end of the bottom of the upper insulation board in the pressure regulating cabinet. A fan is fixedly installed in the middle of the top of the pressure regulating cabinet, and a first air duct is fixedly installed at the output end of the fan. A second air duct is fixedly installed at the rear end of the pressure regulating cabinet, and a connecting pipe is fixedly installed at the middle of the rear end of the second air duct, extending through to the outside of the pressure regulating cabinet.

[0009] Preferably, the dimensions of the horizontal insulation plate in the pressure regulating cabinet are consistent with the internal dimensions of the pressure regulating cabinet, and the dimensions of the vertical insulation plate in the pressure regulating cabinet are consistent with the internal dimensions of the pressure regulating cabinet. The upper insulation plate in the pressure regulating cabinet has through holes, and the insulation plate is set in a corresponding position to the fan. The left and right insulation plates in the pressure regulating cabinet also have through holes, and the insulation plates are set in a corresponding position to the installation compartment.

[0010] Preferably, the first duct is arranged in a "U" shape, and the lower end of the first duct is fixedly connected to the connecting pipe.

[0011] Preferably, the front end of the second duct is fixedly equipped with an air outlet, and the air outlets are arranged in an array with respect to the horizontal line of the second duct body.

[0012] Preferably, an adjusting cylinder is fixedly installed at the right end of the horizontal pipe body of the first air duct, and the adjusting cylinder is connected to the first air duct. Furthermore, exhaust ports are fixedly installed at both ends of the adjusting cylinder near the first air duct, and the exhaust ports are connected to the adjusting cylinder.

[0013] Preferably, a lead screw is rotatably connected to the right end of the adjusting cylinder, and the left end of the lead screw extends through into the interior of the adjusting cylinder. A baffle is fixedly installed at one end of the lead screw inside the adjusting cylinder, and the lead screw and the baffle are rotatably connected together. The inner wall of the lead screw is connected to the adjusting cylinder by a thread, and the lead screw drives the baffle to form a telescopic structure.

[0014] Preferably, the baffle and the regulating cylinder are the same size, and the baffle and the exhaust port are set in a corresponding state, and the length of the baffle is greater than the diameter of the first air duct.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The heating device of the natural gas pressure regulating equipment can increase the temperature of natural gas by heating it, thereby reducing the gas density, improving fluidity, and ensuring smooth gas flow in the pipeline. At the same time, by increasing the temperature, it can prevent moisture condensation, avoid pipeline blockage and damage to other equipment. Then, by heat preservation, it can effectively isolate the external environment, reduce the loss of heat during gas transportation and regulation, and reduce the energy consumption of heat or heating, thereby improving the overall energy efficiency ratio. Furthermore, by venting excess hot gas, it can prevent the equipment or pipeline from overheating, ensuring that it operates within a safe temperature range and maximizing the utilization rate of thermal energy.

The second air duct has horizontally arranged air outlets. When the fan is started, the heat generated by the heater is returned through the cooperation between the first air duct, the connecting pipe, and the second air duct. At the same time, it is discharged through the air outlets arranged in the array at the front end of the second air duct. The heat discharged through the air outlets fills the interior of the pressure regulating cabinet. By heating the gas, the temperature of the natural gas can be increased, thereby reducing the gas density, improving fluidity, ensuring smooth gas flow in the pipeline, and preventing moisture condensation, thus avoiding pipeline blockage and equipment damage.

[0017] 2. The system is equipped with a pressure regulating cabinet, mounting slots, insulation boards, and bolts. Mounting slots are fixedly installed at the top and bottom of the pressure regulating cabinet, as well as at both ends inside the cabinet. Insulation boards are slidably connected to the mounting slots and then fixed together with bolts. This combination effectively prevents external wind from entering and external heat from escaping, while also providing insulation. The insulation effectively isolates the system from the external environment, reducing heat loss during gas transport and regulation. Furthermore, the insulation reduces energy consumption for heating or warming, thereby improving the overall energy efficiency ratio.

[0018] 3. The system is equipped with an adjusting cylinder, an exhaust port, and a lead screw. The lead screw is connected to the inner wall of the adjusting cylinder via a thread, which in turn drives a baffle to form a telescopic structure. The baffle is positioned to correspond to the exhaust ports at both ends of the adjusting cylinder. The extension and retraction of the baffle can block and open the exhaust ports. The adjusting cylinder is also connected to the first air duct, and the extension and retraction of the baffle can adjust the airflow rate inside the first air duct.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a heating device for a natural gas pressure regulating equipment, comprising: a pressure regulating cabinet 1, a gas pressure regulator 2, an installation chamber 3, a heater 4, an installation groove 5, an insulation board 6, bolts 7, a temperature detector 8, a fan 9, a first air duct 10, a second air duct 11, an air outlet 12, a connecting pipe 13, an adjusting cylinder 14, an exhaust outlet 15, a lead screw 16, and a baffle 17.

[0027] First, as attached Figure 1 Appendix Figure 2 and attached Figure 4 As shown, when natural gas is pressure regulated and transported through the gas pressure regulator 2 inside the pressure regulating cabinet 1, the gas pressure regulator 2 is placed inside the pressure regulating cabinet 1, making the gas pressure regulator 2 a closed space. When the gas pressure regulator 2 transmits natural gas, the inner top and inner top of the pressure regulating cabinet 1 are fixedly installed with mounting grooves 5, and the left and right ends of the pressure regulating cabinet 1 are also fixedly installed with mounting grooves 5. The insulation plate 6 is slidably connected inside the mounting groove 5, and the mounting groove 5 and the insulation plate 6 are fixedly connected together with bolts 7. The insulation plate 6 at the top of the pressure regulating cabinet 1 has through holes, which are set in a corresponding state with the fan 9. The insulation plates 6 on the left and right sides of the pressure regulating cabinet 1 also have through holes, which are set in a corresponding state with the installation compartment 3. The mutual cooperation between the mounting groove 5 and the insulation plate 6 isolates the external environment.

[0028] As attached Figure 1 Appendix Figure 2 and attached Figure 3As shown, when natural gas is transported through the gas pressure regulator 2, a temperature detector 8 is fixedly installed at the left end of the bottom of the upper insulation plate 6 in the pressure regulating cabinet 1. When the temperature detector 8 detects that the temperature inside the pressure regulating cabinet 1 is too low, the heater 4 inside the installation compartment 3 is activated. Since the installation compartment 3 is symmetrically arranged about the vertical central axis of the pressure regulating cabinet 1, the heater 4 is also arranged in an array about the horizontal line of the installation compartment 3. Furthermore, the installation compartment 3 is arranged in a corresponding state with the through holes on the insulation plate 6, thereby generating heat in the heater 4. The heater 4 can then heat the gas pressure regulator 2 and other equipment inside the pressure regulating cabinet 1. At the same time, when the heater 4 heats the inside of the pressure regulating cabinet 1, the insulation plate 6 effectively dissipates heat. The interaction between the heater 4 and the insulation plate 6 also reduces the energy consumption for heating or increasing the temperature of the heater 4. When the internal temperature of the pressure regulating cabinet is increased, the fan 9 can be started at the same time. The output end of the fan 9 is fixedly installed with the first air duct 10, and the second air duct 11 is fixedly installed at the rear end of the pressure regulating cabinet 1. The front end of the second air duct 11 is arranged with air outlets 12 in a horizontal array, and the rear end of the second air duct 11 is fixedly installed with a connecting pipe 13. The first air duct 10 is fixedly connected to the connecting pipe 13 in a "U" shape. Thus, the start of the fan 9 can transfer the heat inside the pressure regulating cabinet 1 to the inside of the second air duct 11 through the cooperation between the first air duct 10 and the connecting pipe 13, and then discharge it through the air outlets 12 arranged in the array of the second air duct 11. Thus, the fan 9 can realize heat return and the air force generated by the fan 9 can make the heat distribution inside the pressure regulating cabinet 1 more uniform, so as to increase the internal temperature of the pressure regulating cabinet 1, thereby ensuring the smooth flow of gas in the pipeline and improving the fluidity.

[0029] As attached Figure 3 and attached Figure 5As shown, when the heat inside the pressure regulating cabinet 1 is returned by the fan 9 and the generated airflow makes the heat distribution more uniform, in order to avoid the heat inside the pressure regulating cabinet 1 from being too high and damaging the equipment, the screw 16 can be rotated. Since the inner wall of the regulating cylinder 14 is connected to the screw 16 by a thread, and a baffle 17 is fixedly installed at one end of the screw 16 inside the regulating cylinder 14, and the baffle 17 is rotatably connected to the screw 16, the rotation of the screw 16 drives the baffle 17 to form a telescopic structure inside the regulating cylinder 14. Since exhaust ports 15 are fixedly installed at both ends of the regulating cylinder 14, and the regulating cylinder 14 and the exhaust ports 15 are set in a corresponding state, the regulating cylinder 14 is also fixedly installed at the right end of the first air duct 10 of the horizontal pipe body, and the first air duct 10 is also connected to the regulating cylinder 14. Then, the size of the baffle 17 is the same as that of the regulating cylinder 14, and the baffle 17 is also set in a corresponding state with the exhaust port 15. The length of the baffle 17 is greater than the diameter of the first air duct 10. When the baffle 17 slides to the right inside the regulating cylinder 14, the baffle 17 releases the blockage of the exhaust port 15, thereby connecting the first air duct 10, the regulating cylinder 14 and the exhaust port 15. A small amount of heat is discharged by the fan 9. At the same time, when the baffle 17 slides to the left inside the regulating cylinder 14, the baffle 17 closes the exhaust port 15 again. At the same time, the baffle 17 slides into the first air duct 10 and controls the air force generated by the fan 9 to discharge excess heat. The heat can prevent the equipment or pipeline from overheating and ensure that it operates within a safe temperature range, thereby maximizing the utilization rate of heat.
