Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a valve for real-time leak detection. Background Technology
[0002] Valves are tools used to control the flow of fluids, cut off or regulate the flow rate, and are widely used in various fluid transportation systems. However, during long-term use, valves are prone to leakage due to factors such as media corrosion and aging of seals. Leakage not only leads to fluid waste but may also cause safety accidents, which are quite serious. Therefore, it is necessary to regularly check valves for leakage.
[0003] When valves are located in places inconvenient for personnel to inspect, leaks are difficult to detect, and prolonged leaks can cause accidents and economic losses. To overcome these shortcomings, existing technology (Chinese patent application number 202421148957.6, application date 2024-05-24) describes a valve with leak detection and alarm functions. This involves pressing a telescopic trigger button to activate the valve and collecting leaking fluid in a water tank. When the fluid flows into the drain pipe, the positive and negative contacts form a closed-loop circuit. The telescopic trigger button and electrode connector simultaneously transmit signals to the controller, indicating a fluid leak and promptly sending information to the control terminal. This allows for quick monitoring and maintenance of valves that are difficult to inspect. However, in actual use, this device relies on the positive and negative contacts being immersed in liquid fluid to form a closed-loop circuit for leak detection. Over time, this method can lead to rust or corrosion of the contacts, affecting the sensitivity of the closed-loop circuit and potentially causing them to become unusable. This results in a limited lifespan and poor practicality.
[0004] To address the aforementioned issues, innovative design based on existing equipment is urgently needed. Therefore, we proposed a valve that can detect leaks in real time, which can effectively solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a valve for real-time leakage detection, in order to solve the problem that the aforementioned devices in the background art, when used in actual use, form a closed-loop circuit by immersing the positive and negative contact heads in the liquid fluid to achieve fluid leakage detection. However, long-term use of this method will cause the positive and negative contact heads to rust or corrode, thereby affecting the sensitivity of forming the closed-loop circuit, and even directly leading to scrapping and damage, resulting in a limited service life and poor practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve for real-time leak detection, comprising a valve body, with an inlet pipe and an outlet pipe fixedly installed on both sides of the valve body; a detection box is detachably installed at the bottom of the valve body, and the internal space of the detection box is equally divided into three areas by two partitions formed on the inner wall, and the three areas are respectively aligned with the valve body, the connection between the valve body and the inlet pipe, and the connection between the valve body and the outlet pipe below; a receiving seat is slidably connected to the inner side of each of the three areas, and a sliding rod is fixedly connected to the bottom end of the receiving seat, and the bottom end of the sliding rod slides through to the outer side of the bottom end of the detection box and is fixedly installed with a positive contact head; a balance spring is fixedly connected between the receiving seat and the inner wall of the bottom end of the detection box; a support frame is fixedly connected to the bottom end of the detection box, and three negative contacts corresponding to the three positive contacts are fixedly installed on the inner wall of the bottom end of the support frame, and three warning lights corresponding to the three negative contacts are also installed on the end wall of the support frame; a controller is fixedly installed on the outer wall of the bottom end of the support frame.
[0007] Preferably, both sides of the valve body are connected to the inlet pipe and the outlet pipe through connecting flanges at the ports, and the connecting flanges are tightly fixed by a plurality of evenly distributed embedded screws.
[0008] Preferably, the top of the detection box and the partition are both formed with an arc design that matches the outer diameter of the valve body, the inlet pipe, and the outlet pipe, so that the top of the detection box and the partition can fit tightly against the outer wall of the pipe.
[0009] Preferably, the top of the testing box has four notches for tight engagement of the connecting flange.
[0010] Preferably, each set of positive contact head, negative contact head and warning light is electrically connected to the controller.
[0011] Preferably, the testing box is installed using an installation assembly, which includes mounting plates formed at the four corners of the top of the testing box, and sliding plates are slidably inserted between two mounting plates on the same side, with a connecting plate fixedly connected to the ends of the two sliding plates.
[0012] Preferably, the sliding plate has a vertically elastic sliding rod in the middle, and the bottom end of the elastic rod is fixedly connected to a limiting block, and the two limiting blocks are respectively inserted into the top of the water inlet pipe and the water outlet pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This valve for real-time leakage detection is configured by the cooperation of the detection box, the receiving seat, the sliding rod and the balance spring. When the liquid leaks, the positive contact head will move down to fit the negative contact head to form a closed loop circuit. Then the controller transmits data and controls the warning light to light up, so as to remind the staff to repair the leak in time. Moreover, the positive and negative contact heads in this structure do not need to contact the liquid, thereby ensuring the long-term sensitivity of the closed loop circuit, extending the service life and enhancing the practicality of the device. The specific contents are as follows: (1) By the cooperation of the detection box, the receiving seat, the sliding rod and the balance spring, when the liquid leaks to a certain amount, the positive and negative contact heads will fit together to form a closed loop circuit. The controller transmits data and controls the warning light to light up, so as to remind the staff to repair the leak in time. Moreover, the positive and negative contact heads in this structure do not need to contact the liquid, thereby ensuring the long-term sensitivity of the closed loop circuit, extending the service life and enhancing the practicality of the device.
[0014] By dividing the receiving seat, sliding rod, balance spring, and positive contact head into three independent detection components through two partitions, leakage detection can be performed on the valve body, the connection between the valve body and the inlet pipe, and the connection between the valve body and the outlet pipe. The illumination of warning lights at different locations makes the location and judgment of the leakage more accurate, thereby speeding up the maintenance efficiency.
[0015] The test box can be installed on the outside of the pipeline by inserting two sliding plates between the two mounting plates. The test box can be easily disassembled by simply pulling the connecting plate to remove the two sliding plates from the mounting plate, so as to facilitate the inspection and replacement of internal parts.
[0016] By using the elastic rod to push the limiting block to the top of the inlet and outlet pipes, the sliding plate and the pipe can be axially limited, and then the detection box can be axially limited to ensure its installation stability. Attached Figure Description

[0019] 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.
[0020] Example 1: Please refer to Figures 1-4 The present invention provides the following technical solution: a valve for real-time leakage detection, comprising a valve body 1, wherein an inlet pipe 2 and an outlet pipe 3 are fixedly installed on both sides of the valve body 1 respectively, and both sides of the valve body 1 are connected to the inlet pipe 2 and the outlet pipe 3 through a connecting flange 4 at the port, and the connecting flange 4 is tightly fixed by a plurality of evenly distributed embedded screws to ensure the tightness and stability of the connection.
[0021] A test box 5 is detachably installed at the bottom of the valve body 1. The top of the test box 5 has four notches for the connection flange 4 to fit tightly, further enhancing the connection tightness of the flange 4 and preventing leaked fluid from flowing out. The internal space of the test box 5 is equally divided into three areas by two partitions 6 formed on the inner wall. These three areas are respectively aligned below the valve body 1, the connection between the valve body 1 and the inlet pipe 2, and the connection between the valve body 1 and the outlet pipe 3. Each of the three areas has a slidingly connected receiving seat 7. A sliding rod 8 is fixedly connected to the bottom end of the receiving seat 7, and the bottom end of the sliding rod 8 slides through to the outer side of the bottom end of the detection box 5 and is fixedly installed with a positive contact head 10. A balance spring 9 is fixedly connected between the receiving seat 7 and the inner wall of the bottom end of the detection box 5. The top ends of the detection box 5 and the partition 6 are both formed with an arc design that matches the outer diameter of the valve body 1, the inlet pipe 2, and the outlet pipe 3. This allows the top ends of the detection box 5 and the partition 6 to fit tightly against the outer wall of the pipe, so as to ensure that water can drip stably onto the receiving seat 7 at the leakage point.
[0022] Furthermore, a support frame 11 is fixedly connected to the bottom of the detection box 5, and three negative contacts 12 corresponding to the three positive contacts 10 are fixedly installed on the inner wall of the bottom of the support frame 11. Three warning lights 14 corresponding to the three negative contacts 12 are also installed on the end wall of the support frame 11. A controller 13 is fixedly installed on the outer wall of the bottom of the support frame 11. Each set of positive contacts 10, negative contacts 12 and warning lights 14 are electrically connected to the controller 13 through wires (wires are not shown in the figure).
[0023] By coordinating the detection box 5, the receiving seat 7, the sliding rod 8, and the balance spring 9, when there is a liquid leak at the valve body 1, the inlet pipe 2, or the outlet pipe 3, the liquid will drip and accumulate on the receiving seat 7. When the total weight of the accumulated water and the receiving seat 7 exceeds the elastic support force of the balance spring 9, the balance spring 9 will contract. The receiving seat 7, the sliding rod 8, and the positive contact head 10 will move downwards synchronously. In this way, the positive contact head 10 and the negative contact head 12 will come into contact to form a closed-loop circuit. The controller 13 receives the signal and transmits the data to the terminal, and at the same time controls the warning light 14 to light up to remind the staff to repair the leak in time. Moreover, the positive contact head 10 and the negative contact head 12 in the above structure do not need to come into contact with the liquid, thereby ensuring the long-term sensitivity of the closed-loop circuit, extending the service life, and enhancing the practicality of the device. By dividing the receiving seat 7, sliding rod 8, balance spring 9, and positive contact head 10 into three independent detection components through two partitions 6, leakage detection can be performed on the valve body 1, the connection between valve body 1 and water inlet pipe 2, and the connection between valve body 1 and water outlet pipe 3 respectively. The illumination of warning lights 14 at different positions makes the location and judgment of the leakage more accurate, thereby speeding up the maintenance efficiency.
[0024] Example 2: Based on Example 1, please refer to... Figure 2 , Figures 5-6 The testing box 5 is installed using an installation assembly, which includes mounting plates 15 formed at the four corners of the top of the testing box 5. Sliding plates 16 are slidably inserted between two mounting plates 15 on the same side, and connecting plates 17 are fixedly connected to the ends of the two sliding plates 16. By inserting the two sliding plates 16 between the two mounting plates 15, the testing box 5 can be installed on the outside of the pipeline. The testing box 5 can be easily disassembled by simply pulling the connecting plate 17 to remove the two sliding plates 16 from the mounting plates 15, so as to facilitate the inspection and replacement of the internal parts of the testing box 5.
[0025] Furthermore, an elastic rod 18 is vertically and elastically slidable in the middle of the sliding plate 16, and a limiting block 19 is fixedly connected to the bottom end of the elastic rod 18. The two limiting blocks 19 are respectively inserted into the top of the water inlet pipe 2 and the water outlet pipe 3. By pushing the limiting blocks 19 with the elastic rod 18, they are stably inserted into the top of the water inlet pipe 2 and the water outlet pipe 3, which can axially limit the sliding plate 16 and the pipe, and then axially limit the detection box 5 to ensure its installation stability.
