[0002] With the acceleration of modern urbanization and the improvement of quality of life, heating systems have become an indispensable winter heating facility for many families and public places. However, during the long-term operation of the heating system, radiators, pipes or other components may leak due to various reasons (such as pipe aging, loose interfaces, unstable pressure, external force impact, etc.). Leakage not only leads to waste of water resources, but also may damage interior decoration and even cause safety hazards. Traditional heating systems mostly rely on regular manual inspections or residents to discover water leaks by themselves. This method not only has a delayed response, but also makes it difficult to achieve 24-hour all-weather monitoring.

[0027] A method for using the above-mentioned heating water leakage automatic detection and closing device comprises: S1. When the detection sensor detects water leakage in the heating system, the controller will send a signal to the water diversion valve body 7 on each branch to block it separately; S2, after the water-dividing valve body 7 is closed, the circulating pump 9 pumps out the water flow in the branch; S3, the extracted water flow is circulated from other intact branches through the circulation pump 9; S4.

When the maintenance personnel are doing maintenance, they can inspect the branch line with water leakage without shutting down the water inlet main pipe 16; S6. After the maintenance is completed, the maintenance personnel can restart the branch. Example 2 Further illustrate with reference to Example 1, Figure 1-6 The structure shown, refer to Figure 3-6 A heating water leakage automatic detection and closing device comprises: a water distribution pipe having a water inlet channel, a first pipe joint having a plurality of first pipe joints, the plurality of first pipe joints being arranged on the water distribution pipe at intervals, and the plurality of first pipe joints being connected to the water inlet channel; a water distribution valve body having a plurality of water distribution valve bodies, the plurality of water distribution valve bodies being arranged in the water inlet channel, each water distribution valve body being connected to a first pipe joint, the water distribution valve body having a first passage and a second passage, the first passage and the second passage being connected to the water inlet channel; a controller being arranged on the water distribution pipe, and after the heating water leaks, the controller controls the water distribution valve body to close the first passage.

[0028] In the above scheme, it is mainly composed of a water distribution pipe 1, a first pipe joint 3, a water distribution valve body 7 and a controller, and its specific working method is as follows: the device first includes a water distribution pipe 1, which is provided with a water inlet channel 101 inside, which is used to distribute the hot water of the heating system to each radiator or heating pipe. A plurality of first pipe joints 3 are arranged at intervals on the water distribution pipe 1, and each first pipe joint 3 is connected to the water inlet channel 101 to transmit the hot water to the corresponding radiator or heating pipe. A water distribution valve body 7 is installed at the position corresponding to each first pipe joint 3, and the water distribution valve body 7 is designed with a first passage 701 and a second passage 702. Both passages are connected to the water inlet channel 101. Under normal circumstances, hot water can flow to the radiator through the first passage 701. The controller is installed on the water distribution pipe 1 and is responsible for real-time detection and control of the working status of the entire heating system.

[0029] Once a water leak is detected in the heating system, the controller will immediately take action to control the corresponding water diversion valve body 7 to close the first passage 701 through an electrical signal, thereby preventing hot water from continuing to flow to the radiator or heating pipe where the water leak occurs, effectively preventing the waste of water resources and further damage to the interior decoration. For example, the controller can be connected to a water leak detection sensor, and when the sensor detects a water leak signal, the controller immediately starts a shutdown program to ensure that the water supply to the leaking radiator or heating pipe is cut off in the shortest time after the water leak occurs.

[0030] In this way, compared with the traditional heating system that relies on manual inspection to find water leakage, the present invention realizes automatic detection and shutdown of water leakage, greatly improving the safety, reliability and user experience of the heating system. At the same time, during the repair of the leaking radiator, other unaffected radiators can still provide heating normally, ensuring the uninterrupted operation of the overall heating system.

[0031] Furthermore, the water diverter valve body comprises: a shell, a first passage and a second passage are both opened in the shell, the shell has a flow limiting port, the first passage and the second passage are connected through the flow limiting port; a control rod is slidably arranged in the shell; a spring is sleeved on the control rod, one end of the spring abuts against the inner wall of the shell, and the other end abuts against the control rod. A blocking block is arranged on the control rod, and after the controller controls the control rod to move downward, the control rod drives the blocking block to block the flow limiting port.

[0032] In the above scheme, the core component of the water diverter valve body 7 is a shell 707, and a first passage 701 and a second passage 702 are provided inside the shell, and the two are connected to each other through a flow restriction port 703. A slidable control rod 706 is provided inside the shell 707, and the control rod can move up and down under the command of the controller. A spring 705 is sleeved around the control rod 706, one end of the spring is tightly against the inner wall of the shell 707, and the other end is connected to the control rod 706. The spring usually maintains a certain preload force to keep the control rod in the initial position, ensuring that part of the hot water can smoothly flow through the flow restriction port 703 to the first passage 701, and finally flow to the radiator. The first blocking block 704 is fixed to the lower part of the control rod 706. When the controller detects that the heating system is leaking, the controller will send an instruction to move the control rod 706 downward. Subsequently, the first blocking block 704 attached to the control rod moves downward along with the control rod, and accurately blocks the flow restriction port 703 and the water inlet 301 of the first pipe joint 3, thereby cutting off the water supply from the first passage 701 to the leaking radiator.

[0033] In this way, the device can quickly shut down leaking radiators through precise control, which not only avoids the waste of water resources, but also reduces the impact of leakage on the indoor environment, ensuring the normal operation of the heating system and the safety and comfort of the user's living environment.

[0034] Furthermore, the first pipe joint has a water inlet, one end of the first passage is connected to the water inlet channel, and the other end is connected to the water inlet; both ends of the second passage are connected to the water inlet channel.

[0035] In the above scheme, the first pipe joint 3 has a water inlet 301, which is designed to introduce hot water into the radiator. Specifically, one end of the first passage 701 inside the water diverter valve body 7 is directly connected to the water inlet channel 101 of the water diverter pipe 1, and the other end is connected to the water inlet 301 of the first pipe joint 3. This means that when the water diverter valve body 7 is in an open state, hot water can flow directly into the radiator from the water inlet channel 101 through the first passage 701. At the same time, a second passage 702 is also provided inside the water diverter valve body 7, both ends of which are connected to the water inlet channel 101. Under normal working conditions, the second passage 702 remains unobstructed to ensure that hot water can circulate. Even when the controller closes the first passage 701 of a certain radiator, the remaining unaffected radiators can still normally receive and discharge hot water through the second passage 702 to maintain the continuous operation of the entire heating system.

[0036] It can not only accurately close the leaking radiator, but also does not affect the normal heating of other radiators, ensuring the stability and flexibility of the overall operation of the heating system. In the event of a leak, the controller can quickly respond and instruct the relevant water diversion valve body 7 to close the first passage 701, thereby effectively avoiding water waste and damage to indoor facilities.

[0037] Furthermore, it also includes: a water collecting pipe; a plurality of second pipe joints, wherein the plurality of water collecting pipes are arranged on the water collecting pipe at intervals, and the plurality of second pipe joints are all connected to the water collecting pipe.

[0038] In the above scheme, the water collecting pipe 4 is connected to the return end of the entire heating system as an integral confluence component, and is used to collect hot water flowing back from the radiator. In order to realize the centralized management of multiple radiators, a plurality of second pipe joints 5 are arranged at intervals on the water collecting pipe 4, and each second pipe joint 5 is interconnected with the water collecting pipe 4 itself. Specifically, when the radiator receives hot water through the first pipe joint 3 of the water distribution pipe 1, it is heated, and when the radiator completes the heat exchange, the cooled return water flows back to the water collecting pipe 4 through the second passage 702 of the water distribution valve body 7.

[0039] In this process, each radiator sends the return water back to the water collecting pipe 4 through the corresponding second pipe joint 5, and then uniformly transports it back to the return water main pipe of the heating system. Not only can the device effectively detect and shut down the leakage of a single radiator, but also, through the arrangement of the water collecting pipe 4 and the second pipe joint 5, the centralized management and monitoring of the return water end of the entire heating system is realized, which enhances the flexibility and reliability of the device and is conducive to improving the operating efficiency and safety of the entire heating system.

[0040] Furthermore, it also includes: a circulation pump, which is arranged on the shell, and the circulation pump has a water inlet end and a drainage end; the first pipe joint has a side water outlet; a drainage pipe, one end of which is connected to the side water outlet, and the other end is connected to the drainage end.

[0041] In the above scheme, a circulation pump 9 is installed on the housing 707 of the water diversion valve body 7, and the circulation pump 9 has a water inlet end 901 and a water discharge end 902. The first pipe joint 3 is also provided with a side water outlet. When the controller detects that the radiator is leaking and closes the corresponding first passage 701, the water flowing back from the leaking radiator can flow out through the side water outlet. In order to properly handle and discharge the backflow water that is cut off due to the leakage, the present embodiment specially provides a drainage pipe 14, one end of which is connected to the side water outlet of the first pipe joint 3, and the other end is connected to the water discharge end 902 of the circulation pump 9.

[0042] In this way, when a radiator is shut down due to water leakage, its return water can be directly discharged into the drainage end 902 of the circulation pump through the side water outlet and the drainage pipe 14, effectively preventing the leaked water from flowing back to other unaffected radiators, ensuring the safety and stable operation of the entire heating system. At the same time, this design is also conducive to quickly discovering and locating the water leakage point, which is convenient for subsequent maintenance and treatment.

[0043] Furthermore, it also includes: a baffle, which is located in the first passage and is hinged to the inner wall of the shell, and the baffle is used to block the first passage or the flow limiting port.

[0044] In the above scheme, a baffle 10 is further provided in the first passage 701 of the water diverter valve body 7. The baffle 10 is connected to the inner wall of the shell 707 of the water diverter valve body 7 through a hinge structure, and can be rotated along a preset hinge point to achieve blocking of the first passage 701 or the flow restriction opening 703. Under normal working conditions, the baffle 10 remains in an open state. Under normal working conditions, due to the effect of water flow, the baffle 10 will deflect to the side of the flow restriction opening 703, but will not completely block the flow restriction opening 703 and the first passage 701, so that hot water can flow smoothly from the first passage 701 or the flow restriction opening to the radiator.

[0045] However, when the controller detects that the heating system is leaking and issues a shutdown command, the control rod can be moved downward to push the baffle 10 to rotate, so that it blocks the first passage 701, thereby quickly cutting off the water flow to the leaking radiator. This can ensure that in addition to the control rod 706 and the first blocking block 704, a second fast and effective water flow cutoff means is provided, greatly enhancing the reliability of the device and reducing the risk of overall functional failure of the heating system due to a single point failure.

[0046] It should be noted that when the control rod 706 is intercepting the flow, it can directly push the blocking block to the water inlet for blocking, or directly push the blocking block to the flow limiting port, and cooperate with the baffle to block the first passage.

[0047] Furthermore, the controller includes: a first electromagnet, which is arranged on the shell and is used to control the movement of the control rod; a plurality of detection sensors, which are respectively arranged on the water distribution pipe, the water collection pipe and the heating pipe.

[0048] In the above scheme, the first electromagnet 13 is installed on the shell 707 of the water diversion valve body 7. When the controller receives a water leakage signal, the first electromagnet is energized to generate magnetic force, thereby driving the control rod 706 in the water diversion valve body 7 to move, so that the first blocking block 704 can accurately block the flow limiting port 703 or the water inlet 301, thereby cutting off the water flow of the leaking radiator.

[0049] In addition, in order to realize automatic detection of water leakage, the device is equipped with several detection sensors at key positions of the water distribution pipe 1, the water collection pipe 4 and the heating pipe. These detection sensors monitor the water level, temperature, humidity, pressure and other parameters in their respective areas in real time. Once an abnormal situation is detected, such as a sudden drop in water level, abnormal temperature rise or obvious increase in humidity, etc., which are water leakage characteristics, the signal will be immediately transmitted to the controller.

[0050] The controller determines whether water leakage occurs according to the received signal analysis, and accordingly activates the first electromagnet 13, and promptly shuts off the water supply to the leaking radiator through the control rod 706 and the first blocking block 704, thereby realizing accurate detection and rapid shut-off of water leakage in the radiator. This design greatly improves the safety, intelligence level and fault response efficiency of the heating system.

[0051] Furthermore, it also includes: a protective cap 12, which is arranged on the housing, one end of the control rod extends out of the housing and is located in the protective cap 12, and the first electromagnet is arranged on the protective cap 12. The protective cap 12 is connected to the housing by a screw connection, and a space for the control rod to move is reserved in the protective cap 12. The first electromagnet can be arranged in the protective cap or outside the protective cap.

[0052] Furthermore, it also includes: a bracket; a plurality of fasteners, and the water distribution pipe and the water collection pipe are both set on the bracket through the fasteners. The bracket 2 serves as the main support structure, which is used to fix and support the entire device. The water distribution pipe 1 and the water collection pipe 4 are firmly installed on the bracket 2 through a plurality of fasteners 15), such as screws, nuts or clamps. In this way, whether it is the hot water distribution responsible for the water distribution pipe or the return water collection responsible for the water collection pipe, both can be firmly supported to avoid loose connection or water leakage caused by pipeline shaking or external force.

[0053] This design not only makes the entire heating water leakage automatic detection and shutdown device compact and orderly, but also facilitates the installation, commissioning and maintenance of the device, and enhances its stability and reliability in actual application scenarios. At the same time, the reasonable design of brackets and fasteners can also be flexibly adjusted according to actual conditions to meet the installation requirements of heating systems in different occasions and sizes.

[0054] Furthermore, it also includes: an exhaust valve; a drain valve; a three-way valve, the first end of which is connected to the exhaust valve, the second end of which is connected to the drain valve, and the third end of which is connected to the water distribution pipe and / or the water collection pipe, so as to improve the functionality and safety of the entire heating system. The exhaust valve 8 is mainly used to exhaust the air in the pipeline during the initial water filling or operation of the heating system to ensure that the system is full of water and improve the heating efficiency and safety. After the heating is completed or during the system maintenance stage, the steam and excess water in the system can be discharged through the exhaust valve. The drain valve 6 is used to discharge the remaining water in the system when necessary, such as when repairing, flushing or shutting down the system, by opening the drain valve to drain the water in the radiator and the pipe, to prevent problems such as rust inside the pipe caused by long-term stagnation.

[0055] The three-way valve 11 is a key connecting device, with a first end connected to the exhaust valve 8, a second end connected to the drain valve 6, and a third end connected to the water distribution pipe 1 and / or the water collection pipe 4. The direction of water flow in the heating system can be flexibly controlled and adjusted as needed. For example, when drainage is required, part of the water flow in the water distribution pipe or the water collection pipe can be directed to the drain valve for fast and effective drainage; when exhaust is required, the water flow can be directed to the exhaust valve to quickly exhaust the air in the system.

[0056] Through such a design, the entire heating water leakage automatic detection and shutdown device not only has the water leakage detection and shutdown functions, but can also realize multi-functional operations such as system exhaust and drainage, greatly improving the intelligence level and operation and maintenance convenience of the heating system. Example 3, reference Figure 1~Figure 2 Based on Example 2, this embodiment further discloses a water inlet main pipe 16, which is arranged on the water distribution pipe and connected to the water inlet channel; a control valve, comprising a circulation part 17 and a control part 18, the circulation part 17 is arranged in the water inlet main pipe 16, the control part 18 is arranged above the water inlet main pipe 16, and the control part 18 is used to control the opening and closing of the circulation part 17.

[0057] In the above scheme, the water inlet main pipe 16 is located on one side of the water distribution pipe, and each household is provided with a water inlet main pipe 16. It should be noted that when detecting whether the heating system is leaking, the inspectors usually detect the heating pipes of multiple users on the same floor at the same time. When the heating pipe of one user is leaking, it is only necessary to close the control valve of the water inlet main pipe 16, which does not affect the normal use and detection of other heating systems, nor does it affect the subsequent maintenance and detection of the heating system of the user.

[0058] Furthermore, the control part 18 includes: a bracket 1801, which is arranged on the circulation part 17, and the bracket 1801 has a receiving groove; a slide plate 1830, which is slidably arranged in the receiving groove, and the slide plate 1830 has a through hole; a rotating rod 1821, which is rotatably arranged in the receiving groove, the rotating rod 1821 passes through the through hole and is fixedly arranged in the through hole, and one end of the rotating rod 1821 extending into the circulation part 17 is provided with a second blocking block 19, and the second blocking block 19 is used to block the circulation part 17; a compression spring 1824, one end of which abuts against the top wall of the receiving groove, and the other end abuts against the slide plate 1830, the compression spring 1824 is sleeved on the rotating rod 1821, and the compression spring 1824 is used to press the slide plate 1830; a control member 1802, which is arranged on the bracket 1801, and the control member 1802 is used to control the rotating rod 1821 to move downward and lock.

[0059] In the above scheme, it is intended to achieve more efficient and accurate emergency treatment and maintenance management of water leakage, which is specifically implemented as follows: the water inlet main pipe 16 is located on one side of the water distribution pipe, and a separate water inlet main pipe 16 is set for each household to ensure the independence of each household's heating system. The water inlet main pipe 16 is directly connected to the water inlet channel of each household, which is convenient for centralized management and control. The circulation part 17 is located inside the water inlet main pipe 16 and is responsible for controlling the normal circulation of water. The control part 18 is located above the water inlet main pipe 16 and includes the following key components: bracket 1801: fixed above the circulation part 17, designed with a receiving groove for installing the slide plate 1830 and the rotating rod 1821. The slide plate 1830 is slidably set in the receiving groove of the bracket 1801, and a through hole is opened on the slide plate 1830 to provide a path for the rotating rod 1821 to pass through.

[0060] The rotating rod 1821 is fixed in the through hole of the slide plate 1830, one end of which extends into the circulation part 17 and is equipped with a second blocking block 19, which is used to control the opening and closing of the circulation part 17. The compression spring 1824 is arranged between the slide plate 1830 and the receiving groove, one end of which abuts against the top wall of the receiving groove and the other end abuts against the slide plate 1830, ensuring that the slide plate 1830 remains in the preset position, and at the same time, the position of the second blocking block 19 is adjusted by the action of the rotating rod 1821. The control member 1802 is installed on the bracket 1801, and the rotating rod 1821 can be driven to move downward by the control member 1802, thereby causing the second blocking block 19 to close the circulation part 17 and realize emergency closure.

[0061] When a household's heating pipe is detected to be leaking, the operator only needs to operate the control component 1802 to quickly close the corresponding water inlet main 16 control valve, effectively preventing the leakage problem from expanding while not affecting the heating of other users on the same floor. Through the ingenious design of the rotating rod 1821 and the second blocking block 19, the circulation part 17 can be quickly and accurately opened and closed, improving the efficiency of responding to emergencies. Easy maintenance: The structural design of the control valve facilitates quick inspection and maintenance. When the leaking pipe needs to be repaired, the leaking unit can be isolated by simply operating the control component 1802 without interrupting the heating system of the entire building, which greatly improves the convenience and efficiency of maintenance.

[0062] Furthermore, the control member 1802 includes: a second electromagnet 1825, which is arranged on the bracket 1801, and a block is arranged at the movable end of the second electromagnet 1825, and the slide plate 1830 abuts against the block; a locking member, which is arranged on the top of the bracket 1801, and the locking member includes: an annular rack 1828, which is arranged on the bracket 1801; a turntable 1827, which is fixedly arranged on the rotating rod 1821; a driving part 1826, which is slidably arranged on the side wall of the bracket 1801, and the driving part 1826 moves synchronously with the turntable 1827; an auxiliary gear 1829, which is rotatably arranged on the turntable 1827 and meshes with the annular rack 1828 for transmission; a nut 1822, which is fixedly arranged in the accommodating groove, and the rotating rod 1821 has an external threaded portion 1823, and after the compression spring 1824 is pressed down, the driving part 1826 drives the rotating rod 1821 to rotate, and the external threaded portion 1823 meshes with the nut 1822.

[0063] In the above scheme, the second electromagnet 1825 is installed on the bracket 1801, and a block is installed at its movable end. When the electromagnet is not energized, the block extends into the receiving groove and is located below the slide 1830 to limit the slide 1830. At this time, the compression spring 1824 is in a compressed state, and the block is in contact with the slide 1830. With the help of the force of the compression spring 1824, the slide 1830 is ensured to be in the initial state. The locking member provides a precise position locking function, including: annular rack 1828: fixed on the bracket 1801 to form a circle of continuous racks. The turntable 1827 is fixed on the rotating rod 1821 and rotates synchronously with the rotating rod 1821. The driving part 1826 is slidably arranged on the side wall of the bracket 1801 and connected to the turntable 1827 to ensure that the turntable 1827 is driven to rotate in time. Auxiliary gear 1829: installed on the turntable 1827 and meshing with the annular rack 1828 to achieve precise position control when the turntable 1827 rotates.

[0064] The nut 1822 is fixed in the receiving groove and cooperates with the external thread portion 1823 of the rotating rod 1821. When the driving part 1826 pushes the rotating rod 1821 to rotate, the rotating rod 1821 moves up and down through the engagement of the threads, thereby controlling the opening and closing of the second blocking block 19.

[0065] Working principle: When the system detects a water leakage signal, the second electromagnet 1825 is energized, and the block moves toward the outside of the accommodating groove under the action of electromagnetic force and breaks away from the contact with the slide plate 1830. At this time, the compression spring 1824 pushes the slide plate 1830 to move downward, and the driving part 1826 slides down along the side wall of the bracket 1801, driving the turntable 1827 to rotate, and through the engagement of the auxiliary gear 1829 and the annular rack 1828, the engagement transmission of the rotating rod 1821 and the nut 1822 is precisely controlled, and the second blocking block 19 immediately blocks the flow part 17 to achieve emergency closure.

[0066] When maintenance or adjustment is required, the position of the second blocking block 19 can be accurately controlled by rotating the turntable 1827 with the help of the transmission of the auxiliary gear 1829 and the annular rack 1828 to achieve the purpose of adjusting the water flow. After the adjustment is completed, the electromagnet power supply is disconnected, and the block is reset under the action of the compression spring 1824, and the slide plate 1830 is stuck to maintain the current setting state. The engagement between the nut 1822 and the external threaded portion 1823 of the rotating rod 1821 further ensures the locking of the position. It not only realizes the rapid and automatic response to water leakage incidents, but also provides the flexibility of manual adjustment and the stability of position locking, greatly improving the automation level and operational convenience of the control valve. This design is particularly suitable for residential, commercial buildings and industrial heating systems with high requirements for safety and intelligence, and effectively ensures the conservation of water resources and the safe operation of facilities.
