Description

Technical Field

[0001] This utility model relates to the field of heating network temperature regulation technology, specifically an automatic temperature regulation device for heating networks. Background Technology

[0002] A heating network, also known as a heating pipeline, is a network of heating pipes that originate from boiler rooms, direct-fired engine rooms, heating centers, etc., and run from heat sources to the heat inlets of buildings. Multiple heating pipes form a network. A heating system consists of three main parts: a heat source (heat medium preparation), a heat circulation system (pipeline network or heat medium transportation), and heat dissipation equipment (heat medium utilization).

[0003] In the prior art, a Chinese patent discloses a heating network temperature balance adjustment device (authorization announcement number CN213362647U). This patented technology can facilitate the installation and disassembly of the water outlet mechanism through the first fixing strip and the first mounting bolt, and make the disassembly of the pipeline more convenient by using the first disassembly pipe, the second disassembly pipe and the fixing bolt, thereby making the maintenance and cleaning of the pipeline more convenient.

[0004] However, the aforementioned application regulates water temperature by cooling nozzles to lower the pipe temperature. However, the nozzles spray a relatively low volume of water, which cannot quickly cool the water flow within the pipe, resulting in slow cooling efficiency. Therefore, an automatic temperature regulation device for heating pipe networks is provided to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide an automatic temperature regulation device for heating pipe networks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic temperature regulating device for a heating network includes a controller housing. An inlet pipe and a return pipe are respectively installed on the bottom side of the controller housing. A regulating pipe is fixedly and continuously connected to the lower side of the inlet pipe. A central pipe is fixedly and continuously connected to the lower end of the regulating pipe. A hot water pipe and a cold water pipe are fixedly and continuously connected to the lower side of the central pipe. A medium pipe is fixedly and continuously connected to one end of the regulating pipe. The other end of the medium pipe is fixedly and continuously connected to the central pipe. A push rod is slidably connected inside the medium pipe. A movable plug and a sealing plug are fixedly connected to both ends of the push rod. Paraffin wax is disposed inside the medium pipe.

[0008] As a further embodiment of this utility model: the water inlet pipe is internally fixedly connected to a mounting bracket, and the mounting brackets are screw-connected to each other by fixing bolts to form a filter screen.

[0009] As a further embodiment of this utility model: a heat-conducting plate is fixedly connected inside the regulating tube, and the heat-conducting plate is attached to one end of the medium tube.

[0010] As a further improvement of this utility model, the hot water pipe is internally fixedly connected with multiple flow-blocking plates, and the flow-blocking plates are provided with multiple through holes.

[0011] As a further embodiment of this utility model: the sealing plug and the hot water pipe are mating components, a spring is provided on the upper side of the hot water pipe, and the spring is sleeved on the push rod.

[0012] As a further embodiment of this utility model: wherein the movable plug is slidably connected to the inner wall of the medium tube, and the paraffin wax and the movable plug are mating components.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The system connects to external hot water via a hot water pipe and to external cold water via a cold water pipe. Water from both pipes flows through a central conduit into the regulating pipe. When the water temperature inside the regulating pipe becomes too high, heat is transferred to the paraffin wax inside the medium pipe via a heat-conducting fin. The paraffin wax, affected by the high temperature, changes state (expands when heated), increasing its volume. This increased volume pushes the movable plug downwards, which in turn moves the sealing plug downwards. This reduction in the sealing plug's diameter decreases the flow of hot water into the regulating pipe, while the water volume in the cold water pipe remains constant, thus cooling the regulating pipe. The aforementioned sealing plug and medium pipe system automatically cool the regulating pipe, improving cooling efficiency. Attached Figure Description

Detailed Implementation

[0021] Please see Figures 1-4 An automatic temperature regulating device for a heating network includes a controller housing 1. An inlet pipe 101 and a return pipe 102 are respectively installed on the bottom side of the controller housing 1. A regulating pipe 2 is fixedly and continuously connected to the lower side of the inlet pipe 101. A central pipe 202 is fixedly and continuously connected to the lower end of the regulating pipe 2. A hot water pipe 203 and a cold water pipe 204 are fixedly and continuously connected to the lower side of the central pipe 202. A medium pipe 201 is fixedly and continuously connected to one end of the regulating pipe 2. The other end of the medium pipe 201 is fixedly and continuously connected to the central pipe 202. A push rod 207 is slidably connected inside the medium pipe 201. A movable plug 206 and a sealing plug 209 are fixedly connected to both ends of the push rod 207. Paraffin wax 205 is disposed inside the medium pipe 201.

[0022] The system connects to external hot water via hot water pipe 203 and to external cold water via cold water pipe 204. Water from both pipes flows through the central pipe 202 into the regulating pipe 2. When the water temperature inside the regulating pipe 2 is too high, the paraffin wax 205 changes state due to the high temperature (it expands when heated), increasing its volume. This increased volume pushes the movable plug 206 downwards, causing the sealing plug 209 to move downwards as well. This reduces the flow diameter of the hot water pipe 203, thus decreasing the amount of hot water entering the regulating pipe 2. Meanwhile, the water volume inside the cold water pipe 204 remains constant, effectively cooling the regulating pipe 2.

[0023] Preferably, the water inlet pipe 101 is internally fixedly connected to a mounting bracket 401, and the mounting brackets 401 are spirally connected to each other by fixing bolts 402.

[0024] The filter screen 4 can filter the water and remove impurities from the water in the inlet pipe 101.

[0025] Preferably, a heat-conducting plate 210 is fixedly connected inside the regulating tube 2, and the heat-conducting plate 210 is attached to one end of the medium tube 201.

[0026] Heat is transferred to the paraffin 205 inside the medium tube 201 through the heat-conducting plate 210, which causes the paraffin 205 inside the medium tube 201 to expand rapidly due to heat, thereby pushing the movable plug 206 to move.

[0027] Preferably, the hot water pipe 203 is internally fixedly connected with multiple flow-blocking plates 301, and the flow-blocking plates 301 are provided with multiple through holes 3.

[0028] The baffle plate 301 can reduce the water pressure inside the hot water pipe 203, preventing the sealing plug 209 from failing to move down due to excessive water pressure inside the hot water pipe 203.

[0029] Preferably, the sealing plug 209 and the hot water pipe 203 are mating components, and a spring 208 is provided on the upper side of the hot water pipe 203, which is sleeved on the push rod 207.

[0030] The spring 208 provides auxiliary support for the push rod 207, preventing excessive internal water pressure in the hot water pipe 203 from causing the sealing plug 209 to fail to move down.

[0031] Preferably, the movable plug 206 is slidably connected to the inner wall of the medium tube 201, and the paraffin wax 205 and the movable plug 206 are mating components.

[0032] Among them, the paraffin wax 205 will change its state when affected by high temperature (it will expand when heated), thereby increasing the volume of the paraffin wax 205. When the overall volume of the paraffin wax 205 increases, it will push the movable plug 206 to move down. When the movable plug 206 moves down, it will drive the sealing plug 209 to move down. When the sealing plug 209 moves down, it will reduce the diameter of the hot water pipe 203.

[0033] Working principle: Hot water is connected to the outside through hot water pipe 203, and cold water is connected to the outside through cold water pipe 204. Water from both pipes flows through the central pipe 202 into the regulating pipe 2. When the water temperature inside the regulating pipe 2 is too high, heat is transferred to the paraffin wax 205 inside the medium pipe 201 via the heat-conducting plate 210. The paraffin wax 205 changes state under high temperature (it expands when heated). At low temperatures, paraffin wax 205 is solid; as the temperature rises, it changes from solid to liquid, and then further expands as the temperature increases. The expansion coefficient of liquid paraffin 205 also increases, thereby increasing the volume of paraffin 205. When the overall volume of paraffin 205 increases, it pushes the movable plug 206 downward. When the movable plug 206 moves downward, it drives the sealing plug 209 downward. When the sealing plug 209 moves downward, it reduces the flow diameter of the hot water pipe 203, thereby reducing the amount of hot water entering the regulating pipe 2. Meanwhile, the water volume inside the cold water pipe 204 remains unchanged, thus achieving a cooling effect on the regulating pipe 2. The sealing plug 209 and the medium pipe 201 set above can automatically cool the regulating pipe 2, improving the cooling efficiency.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
