Description

Technical Field

[0001] This utility model relates to the technical field of valve assembly devices, and in particular to a multi-energy supply and return water valve assembly device. Background Technology

[0002] Multi-energy supply and return water valve assembly is a device used for centralized management and control of the supply and return water flow of multiple energy sources (such as hot water, cold water, steam, etc.). It is commonly used in large buildings, industrial facilities, or heating systems to improve energy utilization efficiency, optimize energy distribution, and achieve coordinated operation between different energy systems. It regulates the flow of different energy sources through valves to meet system requirements. The device is equipped with temperature sensors to monitor and regulate the temperature of the supply and return water to ensure the system's operating efficiency. However, most existing multi-energy supply and return water valve assembly devices still have problems that need to be solved.

[0003] In most existing multi-energy supply and return water valve assembly devices, the temperature sensor is typically installed on the device with a welded base or flange, which is inconvenient for disassembly and reassembly. When routine maintenance of the temperature sensor is required or when the temperature sensor malfunctions and needs to be removed for repair, specialized tools and techniques are required for disassembly, which may damage the welded joints and easily damage the pipeline. At the same time, it takes a long time to complete the disassembly and reinstallation, which affects the efficiency of subsequent maintenance of the temperature sensor. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-energy supply and return water valve assembly device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-energy water supply and return valve assembly includes several return water pipes. Each return water pipe has a mounting platform fixedly connected to its outer wall. A fixing sleeve is fixedly connected to the top of each mounting platform. A temperature sensor is mounted on the fixing sleeve. A fixing block, adapted to the fixing sleeve, is located at the bottom of the temperature sensor. The detection probe of the temperature sensor is located inside the return water pipe. Two positioning plates are fixedly connected to the outer wall of the temperature sensor. Each positioning plate has a stop block on its top. One side of each stop block is inclined. Limiting rods are fixedly connected to both ends of the stop block on the side furthest from the temperature sensor. Two limiting rods at the same end are fitted with the same limiting plate. The limiting rods are slidably connected to the limiting plate. The limiting plate is fixedly connected to the outer wall of the return water pipe. A spring is fitted onto each limiting rod and is located between the stop block and the limiting plate. A pressure plate is fixedly connected to one side of each stop block. One side of the pressure plate is inclined. A roller is mounted on the inclined side of the pressure plate. A fixed shaft passes through the roller and is rotatably connected to the fixed shaft. Two fixed shafts at the same end... A connecting plate is fixedly connected to the same side of the device, and a handle is fixedly connected to the bottom of the connecting plate. Due to the use of a fixed sleeve, positioning plate, and stop blocks to restrict the position of the temperature sensor, moving the stop blocks to the top of the positioning plate will confine the temperature sensor within the fixed sleeve, thus securing the temperature sensor. For disassembly, simply pull the handle to move the two stop blocks away from the top of the positioning plate, releasing the restriction on the temperature sensor and allowing it to be removed. This effectively solves the problem mentioned in the background art that temperature sensors on most existing multi-energy supply and return water valve assembly devices are inconvenient to install and remove. Disassembly requires specialized tools and techniques, may damage welding points, easily causing damage to pipelines, and takes a long time to complete, affecting the efficiency of subsequent temperature sensor maintenance. Therefore, this device makes the installation and disassembly of the temperature sensor simpler and faster, eliminating the need for specialized tools, reducing the time required for disassembly and reassembly, and improving the overall system maintenance efficiency.

[0006] As a further embodiment of this utility model, guide rods are provided at both ends of the connecting plate, the connecting plate is slidably connected to the guide rods, and the guide rods are fixedly connected to the outer wall of the return water pipe.

[0007] As a further embodiment of this utility model, two sealing rings are provided inside the bottom of the fixing sleeve, one of which is fixedly connected to the inner wall of the bottom of the fixing sleeve, and the other of which is fixedly connected to the temperature sensor.

[0008] As a further embodiment of this utility model, positioning rods are fixedly connected to the top of both ends of the mounting platform. The positioning rods pass through the positioning plate, and the positioning plate has holes that are compatible with the positioning rods.

[0009] As a further embodiment of this utility model, a solenoid valve is fixedly connected to one side of each of the several return water pipes, and a water supply pipe is fixedly connected to the solenoid valve on the side away from the return water pipe.

[0010] As a further embodiment of this utility model, the outer walls of both the return water pipe and the supply water pipe are fitted with two fasteners, and the two fasteners at the same end are fastened together by bolts.

[0011] As a further embodiment of this utility model, a common support rod is fixedly connected between two adjacent fixing members, and a common base is fixedly connected to the bottom of several support rods located at the bottom end.

[0012] The beneficial effects of this utility model are as follows: By employing a combination of a fixed sleeve, a positioning plate, and a stop block to restrict the position of the temperature sensor, moving the stop block to the top of the positioning plate secures the temperature sensor within the fixed sleeve, thus fixing it in place. For disassembly, simply pulling the handle removes the two stop blocks from the top of the positioning plate, releasing the restriction on the temperature sensor and allowing it to be removed. This effectively solves the problem presented in the background art where temperature sensors in most existing multi-energy supply and return water valve assembly devices are difficult to install and remove. Disassembly requires specialized tools and techniques, may damage welding points, and can easily damage pipelines. It also takes a considerable amount of time to complete disassembly and reinstallation, affecting the efficiency of subsequent temperature sensor maintenance. This technology makes the installation and disassembly of temperature sensors simpler and faster, eliminating the need for specialized tools, reducing the time required for disassembly and reinstallation, and improving the overall system maintenance efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4A multi-energy water supply and return valve assembly includes several return water pipes 1. Each return water pipe 1 has a mounting platform 2 fixedly connected to its outer wall. A fixing sleeve 3 is fixedly connected to the top of each mounting platform 2. A temperature sensor 4 is mounted on the fixing sleeve 3. A fixing block adapted to the fixing sleeve 3 is located at the bottom of the temperature sensor 4. The detection probe of the temperature sensor 4 is located inside the return water pipe 1. Two positioning plates 5 are fixedly connected to the outer wall of the temperature sensor 4. A stop block 6 is located on the top of each positioning plate 5. One side of the stop block 6 is inclined, and the stop block 6 is positioned away from the temperature sensor 4. Limiting rods 7 are fixedly connected to both ends of one side of the pipe. Two limiting rods 7 at the same end are fitted with the same limiting plate 8. The limiting rods 7 are slidably connected to the limiting plate 8. The limiting plate 8 is fixedly connected to the outer wall of the return water pipe 1. A spring 9 is fitted onto the limiting rods 7 and is positioned between the stop block 6 and the limiting plate 8. A pressure plate 10 is fixedly connected to one side of the stop block 6. One side of the pressure plate 10 is inclined, and a roller 11 is installed on the inclined side of the pressure plate 10. A fixed shaft 12 passes through the roller 11, and the roller 11 is rotatably connected to the fixed shaft 12. Two fixed rods 7 at the same end... A connecting plate 13 is fixedly connected to the same side of shaft 12, and a handle 15 is fixedly connected to the bottom of connecting plate 13. Due to the technical means of restricting the position of the temperature sensor by using the cooperation of a fixing sleeve, positioning plate, and stop block, the temperature sensor can be restricted within the fixing sleeve by moving the stop block to the top of the positioning plate, thus fixing the temperature sensor. When disassembling, simply pull the handle to move the two stop blocks away from the top of the positioning plate, thereby releasing the restriction on the temperature sensor and allowing the temperature sensor to be removed. This effectively solves the problem mentioned in the background art that the temperature sensors on most multi-energy supply and return water valve group devices are not easy to disassemble and install. Disassembly requires professional tools and techniques, and may damage the welding points, which can easily damage the pipeline. It also takes a long time to complete the disassembly and reinstallation, affecting the efficiency of subsequent maintenance of the temperature sensor. Thus, it makes the installation and disassembly of the temperature sensor simpler and faster, no longer requiring professional tools, reducing the time required for disassembly and reinstallation, and improving the maintenance efficiency of the entire system.

[0017] In this embodiment, guide rods 14 are provided at both ends of the connecting plate 13. The connecting plate 13 is slidably connected to the guide rods 14, and the guide rods 14 are fixedly connected to the outer wall of the return water pipe 1. When the connecting plate 13 moves, it will move along the guide rods 14 to ensure the stability of the connecting plate 13 when it moves up and down.

[0018] In this embodiment, two sealing rings 16 are provided inside the bottom of the fixing sleeve 3. One sealing ring 16 is fixedly connected to the bottom inner wall of the fixing sleeve 3, and the other sealing ring 16 is fixedly connected to the temperature sensor 4. The two sealing rings 16 are tightly fitted together to seal and prevent water leakage.

[0019] In this embodiment, positioning rods 17 are fixedly connected to the top of both ends of the mounting platform 2. The positioning rods 17 pass through the positioning plate 5. The positioning plate 5 has holes that are compatible with the positioning rods 17. The positioning rods 17 and the positioning plate 5 cooperate to position the temperature sensor 4, ensuring that the temperature sensor 4 is installed in an accurate position.

[0020] In this embodiment, a solenoid valve 18 is fixedly connected to one side of several return water pipes 1. A water supply pipe 19 is fixedly connected to the side of the solenoid valve 18 away from the return water pipe 1. The solenoid valve 18 and the temperature sensor 4 are both connected to the external PLC controller through wires. The temperature sensor 4 detects the water temperature in the return water pipe 1, processes the data and feeds it back to the PLC controller. The PLC controller controls the opening and closing degree of the solenoid valve 18.

[0021] In this embodiment, two fasteners 20 are fitted on the outer walls of both the return water pipe 1 and the supply water pipe 19, and the two fasteners 20 at the same end are fastened together by bolts.

[0022] In this embodiment, the same support rod 21 is fixedly connected between two adjacent fasteners 20, and the bottom of several support rods 21 located at the bottom is fixedly connected to the same base 22.

[0023] Working Principle: During use, water from different sources flows in through the return water pipe 1. The temperature sensor 4 detects the temperature of the incoming water and processes the data, feeding it back to the PLC controller. The PLC controller controls the opening and closing of the solenoid valve 18 to achieve control of the multi-energy water supply and return system. Water is discharged through the solenoid valve 18 to the supply water pipe 19, and then through the fixing component 20 to the balance tank. When routine maintenance of the temperature sensor 4 is required, or when the temperature sensor 4 malfunctions and needs to be removed for repair, the operator can pull the handle 15 to lower it. The handle 15 will drive the connecting plate 13 to descend along the guide rod 14. The connecting plate 13 will drive the fixed shaft 12 to descend, and the fixed shaft 12 will drive the roller 11 to descend and press against the inclined surface of the pressure plate 10. This will cause the two pressure plates 10 to move away from each other. The movement of the pressure plates 10 will drive the stop block 6 to move, and the stop block 6 will drive the limit rod 7 to move along the limit plate 8. The stop block 6 will also press against the pressure plate 10. Spring 9 contracts, and roller 11 continuously presses the pressure plate 10 until the stop 6 moves away from the top of the positioning plate 5, thus releasing the restriction on the positioning plate 5. The positioning plate 5 can then be removed from the positioning rod 17, allowing the temperature sensor 4 to be removed for maintenance or replacement. During assembly, pull handle 15 again to move the two stops 6 away from each other. Insert the temperature sensor 4 into the fixing sleeve 3, place the detection probe into the return water pipe 1, and make the two sealing rings 16 contact. Press the temperature sensor 4 to position the positioning plate 5 onto the positioning rod 17. Continue pressing the temperature sensor 4 until the positioning plate 5 moves to the bottom of the stop 6. Release handle 15, and the contracted spring 9 will extend, allowing the two stops 6 to move closer together and to the top of the positioning plate 5, thus restricting the position of the positioning plate 5 and fixing the temperature sensor 4. The assembly is complete. Follow the same steps to install the other temperature sensors 4.

[0024] 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.
