Description

Technical Field

[0001] This utility model relates to the field of temperature control valves, and in particular to a temperature control valve testing device. Background Technology

[0002] A thermostatic valve is a valve device that automatically adjusts the flow rate of a medium based on temperature changes, thereby controlling the temperature. Its function is to precisely regulate the temperature of the fluid flowing through a pipeline, ensuring that the temperature is maintained within a set range. It is commonly used in heating systems, air conditioning systems, and fluid transport pipelines in industrial production where temperature requirements are stringent. Testing thermostatic valves is necessary to ensure that their temperature control accuracy, sensitivity, and reliability meet requirements, thus guaranteeing the stable and efficient operation of the entire system. Thermostatic valve testing equipment simulates different operating conditions, accurately detecting various performance parameters of the thermostatic valve under various temperature conditions. This helps in selecting qualified products and also facilitates performance evaluation and fault diagnosis of existing thermostatic valves.

[0003] A thermostatic valve testing device typically includes a temperature control system, a flow measurement system, a pressure monitoring system, a drive unit, and a data acquisition and processing system. Its working principle involves the temperature control system creating different temperature environments to simulate actual operating conditions, the drive unit controlling the thermostatic valve's operation, the flow measurement system monitoring changes in the flow rate of the medium passing through the valve, the pressure monitoring system recording the corresponding pressure conditions, and then the data acquisition and processing system collecting and analyzing this real-time data to determine the thermostatic valve's performance under different temperature settings, such as temperature control accuracy and flow regulation capability, to determine whether they meet standard requirements.

[0004] In existing technologies, some devices primarily focus on the performance testing of temperature control valves, with their structural design emphasizing core functions such as temperature control, flow rate, and pressure monitoring. However, they lack efficient water filtration and unblocking devices, making it difficult for some devices to automatically clean and unblock the water filtration components. This results in obstructed water flow during testing, affecting the stability of the water flow and the accuracy of the flow rate in the testing device. Consequently, it interferes with the normal testing of the flow regulation capability and other performance characteristics of the temperature control valve during testing. Therefore, a temperature control valve testing device is proposed to solve the above problems. Utility Model Content

[0015] As a further description of the above technical solution:

[0016] The circulation mechanism includes a water collection tank, the bottom of which is fixedly connected to the top of the base.

[0017] As a further description of the above technical solution:

[0018] A pressure pump is installed at the top of both the hot water tank and the cold water tank. A temperature controller is installed outside the hot water tank.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, the sliding ring is driven to slide downward along the fixed rod by the impact of water flow, causing the unblocking column to separate from the filter plate. This allows the water flow to pass through the filter plate into the U-shaped connecting pipe and compress the spring. When the water pressure decreases, the spring returns to its original shape, causing the sliding ring to move in the opposite direction, driving the unblocking column into the filter holes in the filter plate. This causes the blockage impurities to be squeezed out, achieving water filtration and automatic unblocking of the entire filter component. This effectively intercepts impurities, particles, and suspended solids in the water, preventing them from entering the testing mechanism and avoiding blockage, wear, or damage. It also maintains the permeability of the filter plate, ensuring a continuous and stable water flow, reducing test interruptions or abnormalities caused by filter plate blockage, and improving the efficiency and stability of the testing work.

[0029] 2. In this utility model, by rotating the temperature control valve to be tested and the test pipeline to the middle of the two connecting pipes, the two are driven to achieve a tight connection. The first connecting ring and the second connecting ring work together to drive the sealing ring to squeeze and fill the gap between the two, forming a sealing barrier to prevent water leakage and ensure the external sealing of the test mechanism. This effectively prevents water leakage and avoids changes in the test environment due to water leakage. It ensures that the internal parameters of the test mechanism, such as temperature, pressure and water flow, are not affected by external factors, thereby ensuring the accuracy and reliability of the test data.

[0036] 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.

[0037] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a temperature control valve testing device, comprising a base 1, which serves as the basic support structure for the entire device, providing stable placement and bearing for other components. Multiple support rods 2 are fixedly connected to the top of the base 1, evenly distributed on the base 1 and tightly connected to it in a vertical position, providing stable support for the top plate 3 above. The top of the multiple support rods 2 is fixedly connected to the top plate 3, ensuring that the subsequent structure is in a stable horizontal position during operation, preventing water flow obstruction or other malfunctions due to tilting. A hot water tank 4 is fixedly connected to the top of the top plate 3, serving as a container for storing hot water to ensure that the hot water maintains a relatively stable temperature during testing. A cold water tank 5 is fixedly connected to the top of the top plate 3, storing cold water. This, in conjunction with the hot water tank 4, allows the test water temperature to be rapidly cooled, meeting the testing requirements under different temperature conditions.

[0038] A U-shaped connecting pipe 8 is fixedly connected to the bottom of the hot water tank 4 and the bottom of the cold water tank 5. This U-shaped connecting pipe 8 facilitates the connection between the hot water tank 4 and the cold water tank 5, allowing for the flow and mixing of hot and cold water to simulate water flow environments at different temperatures and meet the testing requirements of the thermostatic valve under various operating conditions. A pressure pump 6 is installed at the top of both the hot water tank 4 and the cold water tank 5. The pressure pump 6 provides power to the water flow, increasing the water pressure to ensure stable and controllable flow rate and pressure during the test, thereby more accurately testing the performance of the thermostatic valve under different water flow conditions. A temperature controller 7 is installed externally on the hot water tank 4. The temperature controller 7 includes a control panel and a heating element. The control panel allows operators to accurately set the water temperature inside the hot water tank 4. The outer wall of the heating element is fixedly connected to the inside of the hot water tank 4. By controlling the heating element, precise adjustment of the hot water temperature can be achieved, meeting the specific requirements of hot water temperature in different testing scenarios.

[0039] Two on / off valves 14 are installed in the middle section of the U-shaped connecting pipe 8. One valve 14 controls the flow of hot water, and the other valve 14 controls the flow of cold water. The valves 14 allow the operator to flexibly control the inflow of hot and cold water according to the testing requirements, achieving precise control of the test water temperature. Filter mechanisms are fixedly connected to the inner walls of both ends of the U-shaped connecting pipe 8, a testing mechanism is fixedly connected to the bottom of the U-shaped connecting pipe 8, and a circulation mechanism is fixedly connected to the top of the base 1.

[0040] The filtration mechanism includes two filter plates 9, whose outer walls are fixedly connected to the inner walls of both ends of a U-shaped connecting pipe 8. The filter plates 9 effectively intercept impurities, particles, and suspended solids in the water, preventing them from entering the testing mechanism and avoiding blockage, wear, or damage. A sliding ring 11 is slidably connected to the inner wall of the U-shaped connecting pipe 8, providing a sliding base for subsequent components. Multiple unblocking columns 12 are fixedly connected to the top of the sliding ring 11, used to unblock the filter holes on the filter plates 9. The number of unblocking columns 12 is the same as the number of filter holes on the filter plates 9, and the shape of the unblocking columns 12 matches the shape of the filter holes on the filter plates 9. An anti-clogging component is fixedly connected to the inner wall of the U-shaped connecting pipe 8. Under the impact of water flow, the sliding ring 11 slides up and down along the inner wall of the U-shaped connecting pipe 8, driving the unblocking column 12 to reciprocate within the filter holes, promptly cleaning away impurities clogging the filter holes, maintaining the permeability of the filter plate 9, and ensuring that water can continuously and stably pass through the filter plate 9 into the testing mechanism. A sealing component is fixedly connected to the outer wall of the testing mechanism. The function of the sealing component is to ensure good sealing at the connection points of the testing mechanism, preventing water leakage, thereby preventing water leakage from causing inaccurate measurement of the testing device.

[0041] The anti-clogging component includes multiple fixed rods 10, with both ends of the fixed rods 10 fixedly connected to the inner wall of the U-shaped connecting pipe 8. The inner wall of the sliding ring 11 is slidably connected to the outer wall of the fixed rods 10. The fixed rods 10 provide a sliding path for the movement of the sliding ring 11 and also provide guidance for the movement of subsequent structures. A spring 13 is sleeved on the outside of the fixed pipe. The spring 13 provides elasticity so that the sliding ring 11 can automatically reset after movement. One end of the spring 13 is fixedly connected to the bottom of the sliding ring 11, and the other end of the spring 13 is fixedly connected to the inner wall of the U-shaped connecting pipe 8. When the water flow impact force is large, the sliding ring 11 will be pushed downward, and the spring 13 will be compressed, thereby allowing water to pass through. When the water flow impact force decreases, the spring 13 will push the sliding ring 11 back to its original position, so that the unblocking column 12 can continuously unblock the filter plate 9, preventing the filter plate 9 from becoming severely clogged due to prolonged use.

[0042] Reference Figures 1 to 3The testing mechanism includes two connecting pipes 15. The top of the top connecting pipe 15 is fixedly connected to the middle of the U-shaped connecting pipe 8, providing a stable water flow channel for subsequent temperature measurement and testing procedures. A thermometer 16 is installed inside the top connecting pipe 15, which can accurately measure the temperature of the water entering the testing mechanism in real time, providing crucial data support for evaluating the temperature control effect of the temperature control valve. A mounting ring 19 is fixedly connected to the outer wall of the bottom connecting pipe 15, facilitating the installation of the entire connecting pipe 15 onto other external components. A test pipeline 20 is threadedly connected to the adjacent sides of the two connecting pipes 15. The threaded connection of the test pipeline 20 ensures sealing while facilitating its installation and disassembly, allowing for easy replacement of the temperature control valve under test. A temperature control valve 23 is installed inside the test pipeline 20, which automatically adjusts its opening according to the set temperature value, thereby controlling the water temperature flowing through the test pipeline 20. When the inlet water temperature changes, the temperature control valve 23 will adjust the opening degree of the valve according to the temperature signal sensed by the internal temperature sensor to keep the temperature of the outflowing water within the set range.

[0043] The sealing assembly includes a first docking ring 17, which is fixedly connected to the outer wall of the connecting pipe 15. The first docking ring 17 is used to mate with subsequent components to form a precise sealing structure. A sealing ring 18 is fixedly connected to the outer wall of the first docking ring 17. The sealing ring 18 is made of elastic, wear-resistant, and corrosion-resistant materials such as rubber or silicone, and has excellent sealing performance. Two second docking rings 21 are fixedly connected to the outer wall of the test pipe 20. Each of the two second docking rings 21 has a filling groove 22 on its far side. The outer wall of the sealing ring 18 is detachably connected to the inside of the filling groove 22. Thus, when the test pipe 20 is connected to the connecting pipe 15, the sealing ring 18 is squeezed into the filling groove 22 on the second docking ring 21, filling the tiny gap between the first docking ring 17 and the second docking ring 21, forming a tight sealing barrier, effectively preventing water leakage from the connection.

[0044] Reference Figure 1 and Figure 2The circulation mechanism includes a water collection tank 24, the bottom of which is fixedly connected to the top of the base 1. The water collection tank 24 collects water flowing out of the testing mechanism. A bidirectional water pump 25 is fixedly connected to the inner wall of the bottom of the water collection tank 24. The bidirectional water pump 25 can pump the water in the water collection tank 24 to the hot water tank 4 and the cold water tank 5 respectively according to the testing requirements, realizing the reverse flow and recycling of water. Two return pipes 26 are fixedly connected to the output end of the bidirectional water pump 25. The other end of one return pipe 26 is fixedly connected to the inside of the hot water tank 4, and the other end of the other return pipe 26 is fixedly connected to the inside of the cold water tank 5. The return pipes 26 serve as water delivery channels, guiding the water pumped by the bidirectional water pump 25 to the hot water tank 4 and the cold water tank 5 respectively, thereby ensuring that the hot water tank 4 and the cold water tank 5 can be replenished with water in a timely and stable manner, maintaining the water temperature conditions and water volume balance required for the test. The inner wall of the return pipe 26 is equipped with a one-way valve. The function of the one-way valve is to ensure that the water flow can only flow in a predetermined direction, that is, from the water collection tank 24 through the return pipe 26 to the hot water tank 4 or the cold water tank 5, and to prevent the water from flowing back into the water collection tank 24.

[0045] Working Principle: When testing the temperature control valve, first rotate the temperature control valve to be tested and the test pipeline 20 to the middle of the two connecting pipes 15, so that the two connecting pipes 15 and the temperature control valve are tightly connected. When connecting the test pipeline 20, the mating ring 17 and the mating ring 21 squeeze the sealing ring 18 to fill the gap between them, forming a tight sealing barrier to prevent water leakage and ensure good sealing at the connection of the test mechanism, thus ensuring the accuracy of the test data. Then, turn on the pressure pump 6 on the hot water tank 4 and its corresponding switch valve 14, so that water flows from the hot water tank 4 through the U-shaped connecting pipe 8 to the test mechanism. At the same time, observe the test temperature through the thermometer 16. When the temperature is too high, turn on the pressure pump 6 on the cold water tank 5 and its corresponding switch valve 14, so that the cold water in the cold water tank 5 mixes with the hot water in the hot water tank 4 to achieve the temperature control effect.

[0046] In this process, the filtration mechanism plays a role. When the water flows through the U-shaped connecting pipe 8, impurities in the water are intercepted by the filter plate 9. At the same time, the water flow impacts the sliding ring 11, causing the sliding ring 11 to slide downward along the fixed rod 10, so that the unblocking column 12 separates from the filter plate 9. This allows the water flow to pass through the filter plate 9 and enter the U-shaped connecting pipe 8. At the same time, the spring 13 is compressed. When the water flow pressure decreases, the spring 13 restores its deformation and causes the sliding ring 11 to move in the opposite direction, thereby driving the unblocking column 12 into the filter holes in the filter plate 9, thereby squeezing out the blockage impurities. This achieves filtration of the entire water flow and automatic unblocking of the filter components.

[0047] Water flowing out of the testing unit is collected in the water collection tank 24. The bidirectional water pump 25 on the inner wall of the bottom of the water collection tank 24 works according to the testing requirements. Through the two return pipes 26 connected to the output end, the water is delivered to the hot water tank 4 and the cold water tank 5 respectively, realizing the reverse circulation of water. The one-way valve on the inner wall of the return pipe 26 ensures that the water can only flow from the water collection tank 24 to the water tank in one direction, preventing water backflow. This maintains the water temperature and water volume balance of the hot water tank 4 and the cold water tank 5, providing a stable water source environment for testing, reducing resource waste, and improving testing efficiency and stability.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
