Description

Technical Field

[0001] The utility model relates to the technical field of heating, and more specifically to a leakage protection device for centralized heating. Background Art

[0002] Heating refers to the supply of heat to buildings to maintain a certain indoor temperature. It is a social service that solves the basic living needs of residents in northern my country for heating in winter.

[0003] For example, the Chinese authorized patent with announcement number CN211822688U discloses a protective mechanism for an energy-saving heating device: it includes a body, a heating pipe is arranged on the front side of the body, and a clamping block, a second slider, a second slide groove, a clamping cover, a clamping rod, a limit rod and an ejection mechanism are arranged for coordinated use. Through the use of the clamping block, the second slider and the second slide groove, the protective net can be positioned, installed and disassembled. Through the use of the clamping cover, the clamping rod and the limit rod, the position of the protective net can be fixed. Through the use of the ejection mechanism, the clamping rod can be ejected, which is convenient for the user to disassemble the protective net. This solves the problem that the existing household heating equipment has no function of protecting the heating pipe during use, which easily causes the heating pipe to be damaged after an accidental collision and easily burns the user.

[0004] The protection mechanism in the above-mentioned prior art protects the outside of the entire heating device, but does not have a leakage-proof function, so once a leakage occurs, it will affect the living environment; therefore, it does not meet the existing needs. We have proposed a centralized heating leakage protection device. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a centralized heating leakage protection device, which solves the problem that the protection mechanism in the prior art protects the outside of the entire heating device but does not have a leakage prevention function, thus affecting the living environment once a leakage occurs.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A central heating leakage protection device comprises a heating pipe, both ends of the heating pipe are provided with joints, and one end of the joint is provided with a main heating water pipe;

[0010] The outer circumference of the joint is sleeved with a threaded connector, one end of the main heating water pipe is fixedly connected with an extension interface, the outer circumference of the extension interface is sleeved with three water-absorbing and swelling rubber rings, the extension interface is embedded in the joint, the three water-absorbing and swelling rubber rings are all in contact with the inner wall of the joint, the outer circumference of the main heating water pipe is provided with a threaded groove, and the threaded connector is threadedly connected to the main heating water pipe through the threaded groove;

[0011] The outer circumferential surface of the main heating water pipe is provided with a valve.

[0012] Furthermore, a metal block is fixedly connected to the outer circumference of the heating pipe, and a transparent interception cover is sleeved on the outer circumference of the main heating water pipe, one end of the transparent interception cover is in contact with the metal block and sleeved on the outside of the threaded connector.

[0013] Furthermore, one end of the transparent interception cover is fixedly connected to a magnet ring, and the magnet ring is adsorbed to the metal block.

[0014] Furthermore, the outer circumferential surface of the transparent intercepting cover is fixedly connected with a connecting pipe, the lower end of the connecting pipe is fixedly connected with a reaction cover, a self-heating heating pack is arranged in the reaction cover, and a whistle is arranged on the outer circumferential surface of the reaction cover.

[0015] Furthermore, the threaded connector is in the shape of a regular hexagon as a whole.

[0016] Furthermore, the outer circumferential surface of the extension interface is provided with three positioning grooves, and the three water-swellable rubber rings correspond to the three positioning grooves one by one.

[0017] Furthermore, the initial diameter of the water-swellable rubber ring is smaller than the inner diameter of the joint.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) In this scheme, after the extension interface is inserted into the interior of the joint, the threaded connector is rotated and tightened to make the heating pipe and the main heating water pipe tightly connected, and then the valve is opened to allow the water flow that provides heat energy to flow. When the water flows through the extension interface, the water-absorbing and expanding rubber ring on the outer circumferential surface of the extension interface expands due to contact with water. The expanded water-absorbing and expanding rubber ring will greatly improve the sealing effect between the extension interface and the joint, thereby reducing the possibility of leakage. Since the initial diameter of the water-absorbing and expanding rubber ring is smaller than the inner diameter of the joint, it only expands after contacting water to achieve a sealing effect. Therefore, in the initial stage, the extension interface is easy to insert into the interior of the joint, which is convenient for personnel to install.

[0021] (2) In this scheme, when the water-swelling rubber ring ages and leaks, the leaked water droplets will accumulate in the transparent interception cover to avoid affecting the living environment. When personnel open the valve next time, they can find and deal with it in time. When a serious leakage occurs directly, if personnel have not noticed the leakage, a large amount of leaked water will enter the reaction cover through the connecting pipe. The self-heating heating bag in the reaction cover will produce a large amount of gas when it comes into contact with water. The large amount of gas will eventually pass through the whistle to the outside world, so that the whistle can be blown to alert surrounding personnel, thereby achieving the purpose of timely alarm.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Example

[0030] like Figure 1-4 As shown, a central heating leakage protection device comprises a heating pipe 1, both ends of the heating pipe 1 are provided with joints 101, and one end of the joint 101 is provided with a main heating water pipe 2;

[0031] The outer circumference of the joint 101 is sleeved with a threaded connector 102, one end of the main heating water pipe 2 is fixedly connected with an extension interface 201, the outer circumference of the extension interface 201 is sleeved with three water-absorbing and swelling rubber rings 202, the extension interface 201 is embedded in the joint 101, the three water-absorbing and swelling rubber rings 202 are all in contact with the inner wall of the joint 101, the outer circumference of the main heating water pipe 2 is provided with a threaded groove 203, and the threaded connector 102 is threadedly connected to the main heating water pipe 2 through the threaded groove 203;

[0032] The outer circumferential surface of the main heating water pipe 2 is provided with a valve 3;

[0033] The initial diameter of the water-swellable rubber ring 202 is smaller than the inner diameter of the joint 101 .

[0034] When in use, after inserting the extension interface 201 into the interior of the joint 101, rotate and tighten the threaded connector 102 to make the heating pipe 1 and the main heating water pipe 2 tightly connected, and then open the valve 3 to allow the water flow that provides heat energy to flow. When the water flows through the extension interface 201, the water-absorbing and expanding rubber ring 202 on the outer circumferential surface of the extension interface 201 expands due to contact with water. The expanded water-absorbing and expanding rubber ring 202 will greatly improve the sealing effect between the extension interface 201 and the joint 101, thereby reducing the possibility of leakage. Since the initial diameter of the water-absorbing and expanding rubber ring 202 is smaller than the inner diameter of the joint 101, it only expands after contacting water to achieve a sealing effect. Therefore, in the initial stage, the extension interface 201 is easily inserted into the interior of the joint 101, which is convenient for personnel to install.

[0035] like Figure 2-4 As shown, a metal block 4 is fixedly connected to the outer circumference of the heating pipe 1, and a transparent intercepting cover 5 is sleeved on the outer circumference of the main heating water pipe 2. One end of the transparent intercepting cover 5 is in contact with the metal block 4 and sleeved on the outside of the threaded connector 102.

[0036] During use, when the water-absorbing and swelling rubber ring 202 ages and causes leakage, the leaked water droplets will accumulate in the transparent interception cover 5 to avoid affecting the living environment. When personnel open the valve 3 next time, they can find and deal with it in time when serious leakage occurs directly.

[0037] like Figure 2-3 As shown, one end of the transparent interception cover 5 is fixedly connected to a magnet ring 6, and the magnet ring 6 is adsorbed to the metal block 4.

[0038] When in use, under the adsorption of the magnet ring 6, the stability of the transparent interception cover 5 when in contact with the metal block 4 is improved, and it is also convenient to disassemble.

[0039] like Figure 2-3As shown, the outer circumference of the transparent intercepting cover 5 is fixedly connected with a connecting pipe 7, the lower end of the connecting pipe 7 is fixedly connected with a reaction cover 8, a self-heating heating pack 801 is arranged in the reaction cover 8, and a whistle 9 is arranged on the outer circumference of the reaction cover 8.

[0040] When in use, if the personnel have not noticed the leakage, a large amount of leaked water will enter the reaction cover 8 through the connecting pipe 7. The self-heating heating bag 801 in the reaction cover 8 will produce a large amount of gas after meeting water. A large amount of gas will eventually flow to the outside through the whistle 9, so that the whistle will be blown to alert the surrounding personnel, thereby achieving the purpose of timely alarm.

[0041] like Figure 2 As shown, the threaded connector 102 is in the shape of a regular hexagon as a whole.

[0042] During use, a person can rotate the threaded connector 102 by using a wrench.

[0043] like Figure 4 As shown, three positioning grooves 204 are formed on the outer circumferential surface of the extension interface 201 , and the three water-swellable rubber rings 202 correspond to the three positioning grooves 204 one by one.

[0044] When in use, the water-swellable rubber rings 202 can be evenly spaced on the outer circumferential surface of the extension interface 201 during installation, thereby ensuring the sealing effect of the water-swellable rubber rings 202 .

[0045] In summary, the specific working process of this solution is as follows: after inserting the extension interface 201 into the interior of the joint 101, rotate and tighten the threaded connector 102, so that the heating pipe 1 and the main heating water pipe 2 are tightly connected, and then the valve 3 is opened to allow the water flow that provides heat energy to flow. When the water flows through the extension interface 201, the water-absorbing and expanding rubber ring 202 on the outer circumferential surface of the extension interface 201 expands due to contact with water. The expanded water-absorbing and expanding rubber ring 202 will greatly improve the sealing effect between the extension interface 201 and the joint 101, thereby reducing the possibility of leakage. Since the initial diameter of the water-absorbing and expanding rubber ring 202 is smaller than the inner diameter of the joint 101, it only expands after contacting water to achieve a sealing effect. Therefore, in the initial stage, the extension interface 201 is easily inserted into the interior of the joint 101, which is convenient for personnel to install;

[0046] Among them, when the water-absorbing and swelling rubber ring 202 ages and causes it to leak, the leaked water droplets will accumulate in the transparent interception cover 5 to avoid affecting the living environment. When the personnel open the valve 3 next time, they can find and deal with it in time. When a serious leakage occurs directly, if the personnel have not noticed the leakage, a large amount of leaked water will enter the reaction cover 8 through the connecting pipe 7. The self-heating heating bag 801 in the reaction cover 8 will produce a large amount of gas after meeting water. A large amount of gas will eventually pass to the outside from the whistle 9, so that the whistle can be blown to remind the surrounding personnel, thereby achieving the purpose of timely alarm.

[0047] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
