Description

Technical Field

[0001] This utility model belongs to the technical field of leakage detection equipment, and in particular relates to a water tank structure for actively detecting leakage. Background Technology

[0002] Active leak detection devices are mainly used to detect minor leaks in circulating systems. They achieve automated detection and data uploading through a combination of high-precision differential pressure sensors, tank structure layout, and system software algorithms. This provides technical support for ensuring the normal operation of the system and avoiding the risks that leaks may pose to the main unit's operation. The above workflow determines whether there is a leak in the entire liquid circuit. However, active leak detection devices still have the following drawbacks in practical use:

[0003] When the active leak detection device is in operation, it directly uses the pressure of the comparison pressure detection circuit. However, liquid impact is easily generated in the circuit. After the liquid impact, it is easy to cause errors in the pressure comparison and affect the detection accuracy.

[0004] Secondly, during the testing process, when the liquid content in the circuit decreases, or when testing different circuits, it is necessary to adjust and determine the parameters of each instrument before testing can be carried out. Adjusting various parameters during the testing process requires a lot of operations, making the work inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a water tank structure for active leakage detection. By setting up a water tank body, a detection chamber, a level gauge, a two-way ball valve, and a differential pressure sensor, it solves the problems of easy errors in active leakage detection devices and insufficient applicability to different circuits.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an active leak detection water tank structure, comprising a water tank body, a detection chamber, a level gauge, a two-way ball valve, and a differential pressure sensor. A two-way ball valve is installed on one side of the water tank body. The detection chamber is fixed to the inner wall of the water tank body near the two-way ball valve. Filter cotton is fixed to the lower part of the detection chamber, extending out of the detection chamber and fixed to the bottom of the water tank body. Both ends of the two-way ball valve are fixedly connected to a three-way pipe. The ends of the two three-way pipes away from the water tank body are fixedly connected to a control valve. A differential pressure sensor is installed on the side of the two-way ball valve away from the water tank body. A level gauge is vertically installed on the side of the water tank body away from the two-way ball valve. During operation, water flows through the water tank body and is transported to the detection chamber through the filter cotton in the lower part of the detection chamber. Water is then transported from the detection chamber to the three-way pipe connected to the two-way ball valve. The level gauge measures the water level in the water tank, and the differential pressure sensor measures the difference in water level between the detection chamber and the comparison chamber.

[0008] Furthermore, a comparison chamber is fixed to the inner wall of the water tank on the side adjacent to the detection chamber. The bottom end of the comparison chamber is fixed to the bottom of the water tank. The comparison chamber inside the water tank is used for water level comparison.

[0009] Furthermore, a water supply pipe and a return pipe are fixedly connected to the lower part of the water tank near the two-way ball valve. The water supply pipe and the return pipe are located on the same side of the detection chamber. When the water tank is in operation, water is delivered to the detection circuit through the water supply pipe and returned to the water tank through the return pipe.

[0010] Furthermore, the end of the level gauge closest to the water tank is fixedly connected to a connecting pipe, and the ends of the two connecting pipes furthest from the level gauge are fixedly connected to the water tank. The level gauge is connected to the water tank through the connecting pipes.

[0011] Furthermore, the ends of the two three-way pipes furthest from the control valve are fixedly connected to the water tank, and the ends of the two three-way pipes are respectively connected to the comparison chamber and the detection chamber, so that the comparison chamber and the detection chamber can be connected to each other to calibrate the water level.

[0012] Furthermore, both ends of the differential pressure sensor are fixedly connected to a T-junction pipe 2, and the ends of the two T-junction pipes 2 away from the differential pressure sensor are fixedly connected to a connecting hose. The ends of the connecting hoses away from the T-junction pipes 2 are respectively fixedly connected to two control valves. The ends of the two T-junction pipes 2 between the differential pressure sensor and the connecting hoses are fixedly connected to an exhaust valve. When the pressure at both ends of the differential pressure sensor changes, the pressure change is detected by the differential pressure sensor.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of errors that easily occur in active leak detection devices by setting up a water tank, a detection chamber, a level gauge, and a differential pressure sensor. In operation, when the two control valves are opened, the water pressure at both ends of the differential pressure sensor is the same. When the circuit being detected leaks, the water level in the water tank drops. The water is then transported through the detection chamber to T-pipe 1 and then through the connecting hose to T-pipe 2. After entering the differential pressure sensor, the water pressure drops and is detected by the differential pressure sensor, making it less prone to errors in the active leak detection device.

[0015] This invention solves the problem of insufficient applicability of active leak detection devices to different loops by setting up a water tank, a detection chamber, a level gauge, and a two-way ball valve. During operation, when the water level needs to be calibrated after completing the detection of one loop, the control valves on the two three-way pipes are first closed. After opening the two-way ball valve, the water in the water tank is filtered through the filter cotton in the lower part of the detection chamber and then transported to the three-way pipe connected to the detection chamber. It is then transported through the three-way pipe to the two-way ball valve, and then through the two-way ball valve to another three-way pipe, and finally to the comparison chamber, so that the water levels in the water tank and the comparison chamber are the same. Then the control valves on the two three-way pipes can be opened to start working, making the active leak detection device more applicable to different loops. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to an active leak detection water tank structure, comprising a water tank body 1, a detection chamber 2, a level gauge 3, a two-way ball valve 4, and a differential pressure sensor 5. A two-way ball valve 4 is located on one side of the water tank body 1. During operation, the water tank body 1 contains the water to be detected. The two-way ball valve 4 controls the liquid level balance between the detection chamber 2 and the comparison chamber 101. The detection chamber 2 is fixed to the inner wall of the water tank body 1 near the two-way ball valve 4. During operation, the detection chamber 2 contains the water from the water tank body 1. A filter cotton 201 is fixed to the lower part of the detection chamber 2, extending out of the detection chamber 2 and with its bottom fixed to the inner bottom of the water tank body 1. The filter cotton 201 filters the water in the water tank body 1. The water is then transported to the detection chamber 2. Both ends of the two-way ball valve 4 are fixedly connected to a three-way pipe 401. The three-way pipe 401 transfers the two-way ball valve 4 to the detection chamber 2 and the comparison chamber 101. The ends of the two three-way pipes 401 away from the water tank 1 are fixedly connected to a control valve 402. The control valve 402 controls the connection and disconnection of the three-way pipe 401 and the connecting hose 503. A differential pressure sensor 5 is installed on the side of the two-way ball valve 4 away from the water tank 1. The differential pressure sensor 5 measures the water level pressure difference in the detection chamber 2 and the comparison chamber 101. A level gauge 3 is vertically installed on the side of the water tank 1 away from the two-way ball valve 4. When the level gauge 3 is working, it measures and determines the liquid level in the water tank 1.

[0026] Specifically, a comparison chamber 101 is fixed on the inner wall of the water tank 1 adjacent to the detection chamber 2. The bottom end of the comparison chamber 101 is fixed to the bottom of the water tank 1. When the water tank 1 is working, the water pressure of the detection chamber is compared through the comparison chamber 101.

[0027] Furthermore, a water supply pipe 102 and a return pipe 103 are fixedly connected to the lower part of the side of the water tank 1 near the two-way ball valve 4. The water supply pipe 102 and the return pipe 103 are located on the same side of the detection chamber 2. The end of the water supply pipe 102 away from the water tank 1 is connected to the input end of the circuit being detected, and the return pipe 103 is fixedly connected to the output end of the circuit being detected, so that the water circulates in the water tank 1 during operation.

[0028] Furthermore, the end of the level gauge 3 closest to the water tank 1 is fixedly connected to a connecting pipe 301, and the ends of the two connecting pipes 301 furthest from the level gauge 3 are fixedly connected to the water tank 1. When the level gauge 3 is working, it is connected to the water tank 1 through the connecting pipe 301, so that the level gauge 3 can detect the water level in the water tank 1.

[0029] Furthermore, the ends of the two three-way pipes 401 away from the control valve 402 are fixedly connected to the water tank 1, and the ends of the two three-way pipes 401 are respectively connected to the comparison chamber 101 and the detection chamber 2. When the three-way pipes 401 are in operation, the length and height of the connection with the water tank 1 are the same, so that the water in the comparison chamber 101 and the detection chamber is transported to the connecting hose 503.

[0030] The operation process of this embodiment is as follows: During operation, when the detection of a detection loop is completed and the water level needs to be calibrated, firstly close the control valves 402 on the two three-way pipes 401. After opening the two-way ball valve 4, the water in the water tank 1 is filtered through the filter cotton 201 in the lower part of the detection chamber 2 and then transported to the three-way pipe 401 connected to the detection chamber 2. It is then transported to the two-way ball valve 4 through the three-way pipe 401 and then to the comparison chamber 101 through the two-way ball valve 4. This ensures that the water levels in the water tank 1 and the comparison chamber 101 are the same. Then, the control valves 402 on the two three-way pipes 401 can be opened to start the operation. Specific Implementation Example 2

[0031] Please see Figure 1-3 Based on the first specific embodiment, both ends of the differential pressure sensor 5 are fixedly connected to a two-way pipe 501. The ends of the two three-way pipes 501 away from the differential pressure sensor 5 are fixedly connected to a connecting hose 503. The ends of the connecting hoses 503 away from the three-way pipes 501 are respectively fixedly connected to two control valves 402. The ends of the two three-way pipes 501 between the differential pressure sensor 5 and the connecting hoses 503 are fixedly connected to an exhaust valve 502. When the differential pressure sensor 5 is working, it is fixedly connected to the connecting hoses 503 through the three-way pipes 501, and fixedly connected to the control valves 402 through the connecting hoses 503. The air in the differential pressure sensor 5, the three-way pipes 501 and the exhaust valves 502 are discharged through the exhaust valves 502 on the three-way pipes 501.

[0032] The operation process of this embodiment is as follows: During operation, when it is necessary to vent air from the differential pressure sensor 5, the two-way pipe 501, and the vent valve 502, water is first transported to the circuit of the device under test through the water supply pipe 102, and then output to the water tank 1 through the circuit of the device under test. The two-way ball valve 4 is opened, and the control valve 402 is opened. Then, the vent valve 502 on the two-way pipe 501 is opened. At this time, the water in the water tank 1 is filtered by the filter cotton 201 in the lower part of the detection chamber 2, and then transported to the three-way pipe 401. It is then transported to the two-way ball valve 4 through the three-way pipe 401, and then to another three-way pipe 401. It is then transported to the two control valves 402 through the two three-way pipes 401, and finally to the connecting hose 5. 03. The water is transported to the two-way pipe 2 501 and the differential pressure sensor 5. After the test water is evenly discharged from the two three-way pipes 2 501 to the exhaust valve 502, the two exhaust valves 502 are closed, and then the two control valves 402 are closed. This continues until the water level in the comparison chamber 101 is the same as the water level in the water tank 1. Then the two-way ball valve 4 is closed and the two control valves 402 are opened. At this time, the water pressure at both ends of the differential pressure sensor 5 is the same. When the detected circuit leaks, the water level in the water tank 1 drops. The water is transported through the detection chamber 2 to the three-way pipe 1 401 and then through the connecting hose 503 to the three-way pipe 2 501. After the water pressure in the differential pressure sensor 5 drops, it is detected by the differential pressure sensor 5.
