Description

Technical Field

[0001] This utility model relates to the field of pipeline performance testing technology, and more specifically, to a sewage pipeline performance testing device. Background Technology

[0002] A toilet, also commonly known as a flush toilet, is a sanitary fixture primarily used in homes or public restrooms for people to use when relieving themselves. It cleans waste by flushing with water and is usually connected to the sewer system to ensure proper wastewater drainage. The design of a toilet allows people to sit while using the toilet, providing a more comfortable and convenient experience.

[0003] With the increasing emphasis placed on water-saving performance of bathroom products by the government, various bathroom manufacturers are actively launching more water-saving toilets. Currently, most water-saving toilets on the domestic market rely on the siphon principle to work. However, the evaluation of the siphon performance of toilet drain pipes still involves making toilet prototypes and then testing them to determine the siphon performance of the toilet drain pipes. This testing method is not only time-consuming, but the shape of the toilet's wash surface and different water supply systems can also affect the test results, making it impossible to accurately distinguish the siphon performance of toilet drain pipes.

[0004] In the existing technology, there is a lack of independent sewage pipe performance testing devices, and the problem of how to test the siphon performance of the sewage pipe of a toilet separately is troubling the staff. Utility Model Content

[0005] To overcome the challenges posed by the lack of independent sewage pipe performance testing devices in existing technologies, such as how to independently test the siphon performance of toilet sewage pipes, and the need to improve the practicality and durability of testing devices, this utility model provides a sewage pipe performance testing device, including a test box, a sewage pipe, a test component, and an outlet sealing component. The sewage pipe to be tested is detachably installed on one side of the test box. The top opening of the sewage pipe is connected to a water storage tank located inside the test box. The bottom outlet of the sewage pipe is equipped with an outlet sealing component for controlling the opening and closing of the pipe. The water storage tank is equipped with a test component for detecting the liquid level.

[0006] The sewage pipe to be tested is installed on the test chamber of the testing device. The lower outlet of the sewage pipe is closed by the outlet sealing component. Water is injected into the test chamber to reach the set water level. Then, the outlet of the sewage pipe is opened by the outlet sealing component to start the drainage process. The liquid level detector records the change of liquid level with the drainage time. After that, by analyzing the liquid level change data, the siphon performance of the sewage pipe itself can be quickly evaluated without interference from other parts of the toilet.

[0007] In a preferred embodiment, the testing assembly includes a level detector located on the top of the testing chamber and a control box located on the side wall of the testing chamber. The outlet of the level detector faces the interior of the water storage tank. A controller is installed inside the control box, and a display is installed on the surface of the control box. The level detector is electrically connected to the display through the controller.

[0008] In a preferred embodiment, the liquid level detector is mounted on the center of the top of the test chamber via a mounting plate, and the liquid level detector is an ultrasonic liquid level gauge.

[0009] In a preferred embodiment, the water storage tank is equipped with an inlet valve, and the inlet of the inlet valve is connected to a test water source.

[0010] In a preferred embodiment, the outlet sealing assembly includes a sealing baffle, a fixed rod, and a rotating rod. The fixed rod is installed at the bottom of the test chamber, and the rotating rod is rotatably connected to the bottom of the fixed rod. The sealing baffle is fixedly installed at one end of the rotating rod.

[0011] By installing an outlet sealing component at the bottom of the sewage pipe, a sealing baffle can be placed over the bottom outlet of the sewage pipe by driving a rotating rod. This allows for control of the start time of the siphon process and facilitates the acquisition of stable and reliable test data, bringing convenience to pipeline testing.

[0012] In a preferred embodiment, the enclosed baffle is circular and its diameter is larger than the diameter of the bottom outlet of the sewage pipe.

[0013] In a preferred embodiment, the surface of the closed baffle is provided with a sealing gasket.

[0014] In a preferred embodiment, an observation window is provided in the center of the front of the test chamber, and a water level scale is provided on one side of the observation window.

[0015] The observation window and scale on the surface of the test chamber allow testers to more intuitively view the changes in water level inside the chamber. An inlet valve is installed inside the test chamber to fix the inlet water level, ensuring that the water level can be stably controlled during the test.

[0016] In a preferred embodiment, a fixed flange is provided at the connection between the test box and the sewage pipe. The fixed flange matches the connecting flange located at the opening of the sewage pipe, and a sealing gasket is provided on the surface of the fixed flange.

[0017] In a preferred embodiment, the bottom of the test box is equipped with several support legs, and each support leg is provided with an anti-slip sleeve at its bottom.

[0018] Anti-slip sleeves can improve the anti-slip ability of the supporting legs, making them more stable during the operation of the testing device.

[0019] Beneficial effects:

[0020] The beneficial effects of adopting the technical solution of this utility model are as follows:

Then, by analyzing the data of liquid level change, the siphon performance of the sewage pipe itself can be quickly evaluated without interference from other parts of the toilet.

[0022] (2) The observation window and scale set on the surface of the test chamber can help the tester to see the water level change inside the test chamber more intuitively. The test chamber is equipped with an inlet valve to fix the water level and ensure that the water level can be stably controlled during the test.

[0023] (3) By using the outlet sealing component installed at the bottom of the sewage pipe, the sealing baffle can be placed at the bottom outlet of the sewage pipe by driving the rotating rod to rotate, thereby controlling the start time of the siphon process and making it easier to obtain stable and reliable test data, which brings convenience to the pipeline test.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] This embodiment involves installing the sewage pipe to be tested onto the test chamber of the testing device. The lower outlet of the sewage pipe is closed using an outlet sealing component. Water is then added to the test chamber until a set water level is reached. The outlet of the sewage pipe is then opened again using the outlet sealing component to begin the drainage process. A level detector records the change in liquid level over time during the drainage process. By analyzing the data on the liquid level changes, the siphon performance of the sewage pipe can be determined. The specific implementation method is as follows:

[0033] like Figures 1 to 5 As shown, a sewage pipe performance testing device includes a test chamber 1, a sewage pipe 2, a testing component, and an outlet sealing component. The sewage pipe 2 to be tested is detachably installed on one side of the test chamber 1. The top opening of the sewage pipe 2 is connected to a water storage tank 4 located inside the test chamber 1. An outlet sealing component for controlling the opening and closing of the pipe is provided at the bottom outlet of the sewage pipe 2. The water storage tank 4 is provided with a testing component for detecting the liquid level. The sewage pipe 2 to be tested is installed on the test chamber 1 of the testing device. The lower outlet of the sewage pipe 2 is closed by the outlet sealing component. Water is injected into the test chamber 1 to reach a set water level. Then, the outlet of the sewage pipe 2 is opened by the outlet sealing component to start the drainage process. The liquid level detector 5 records the change of liquid level with the drainage time during the drainage process. By comparing the rate of liquid level change of sewage pipes with different structures, the strength of the siphon effect can be judged, that is, the faster the change, the better the siphon effect.

[0034] Specifically, the testing components include a level detector 5 mounted on the top of the test chamber 1 and a control box 15 mounted on the side wall of the test chamber 1. The outlet of the level detector 5 faces the interior of the water storage tank 4. A controller is installed inside the control box 15, and a display 16 is mounted on the surface of the control box 15. The level detector 5 is electrically connected to the display 16 through the controller. By controlling the level detector 5 with the controller, the level can be detected. Furthermore, the controller can process the changes in the level detected by the level detector 5, facilitating subsequent assessment of the siphon performance.

[0035] Specifically, the level detector 5 is mounted on the top center of the test chamber 1 via the mounting plate 13. The level detector 5 is an ultrasonic level gauge. The ultrasonic level gauge is a digital level instrument controlled by a microprocessor. During measurement, ultrasonic pulses are emitted by the sensor (transducer). The sound waves are reflected by the liquid surface and received by the same sensor. They are converted into electrical signals by a piezoelectric crystal, and the distance from the sensor to the surface of the liquid being measured is calculated by the time between the emission and reception of the sound waves. The mounting plate 13 facilitates the installation and fixation of the level detector 5, and the mounting plate 13 is easy to disassemble and adjust.

[0036] Specifically, the water storage tank 4 is equipped with an inlet valve 12, and the inlet of the inlet valve 12 is connected to a test water source. The water level can be determined through the inlet valve 12, and the water inlet height of the inlet valve 12 can be adjusted in advance. The adjustment principle is that the floating and sinking movement of the float accessory on it drives the valve to close. The inlet valve 12 can also be replaced with an overflow plate. When filling water, the water should be filled to the height of the overflow plate.

[0037] Specifically, the outlet sealing assembly includes a sealing baffle 8, a fixing rod 10, and a rotating rod 11. The fixing rod 10 is installed at the bottom of the test chamber 1, and the rotating rod 11 is rotatably connected to the bottom of the fixing rod 10. The sealing baffle 8 is fixedly installed at one end of the rotating rod 11. By setting the outlet sealing assembly at the bottom of the sewage pipe 2, the start time of the siphon process can be controlled, facilitating data acquisition. By driving the rotating rod 11 to rotate, the sealing baffle 8 is placed over the bottom outlet of the sewage pipe 2, thereby controlling the start time of the siphon process and facilitating the acquisition of stable and reliable test data, bringing convenience to pipeline testing.

[0038] Specifically, the sealing baffle 8 is circular and its diameter is larger than the diameter of the bottom outlet of the sewage pipe 2. Before the water level in the water storage tank 4 rises to the set water level, the outlet of the sewage pipe 2 can be sealed to prevent air leakage. This ensures that the drainage process will not start before the set water level is reached. When the water level in the water storage tank 4 reaches the set water level, the outlet sealing component of the pipe is moved to open the pipe outlet and start the drainage process.

[0039] Specifically, a sealing gasket 14 is provided on the surface of the closed baffle 8. The sealing gasket 14 can improve the sealing performance of the closed baffle 8 when it covers the sewage pipe 2, thus preventing water leakage.

[0040] Specifically, an observation window 6 is provided in the center of the front of the test chamber 1, and a water level scale 7 is provided on one side of the observation window 6. The observation window 6 and the water level scale 7 on the surface of the test chamber 1 can help testers to more intuitively observe the changes in the water level inside the test chamber 1.

[0041] Specifically, a fixing flange 3 is provided at the connection between the test chamber 1 and the sewage pipe 2. The fixing flange 3 matches the connecting flange located at the opening of the sewage pipe 2, and a sealing gasket is provided on the surface of the fixing flange 3. The fixing flange 3 facilitates the tight installation of the sewage pipe 2 and also brings convenience to the performance testing.

[0042] Specifically, the bottom of the test box 1 is equipped with several support legs 9, and each support leg 9 has an anti-slip sleeve on its bottom. The anti-slip sleeve can improve the anti-slip ability of the support legs 9, which play a supporting role, making them more stable during the operation of the test device and less likely to slip or shake and affect the test.

[0043] Working Principle: The sewage pipe to be tested is installed on the test chamber of the testing device. The lower outlet of the sewage pipe is closed by the outlet sealing component. Water is injected into the test chamber to reach the set water level. Then, the outlet of the sewage pipe is opened by the outlet sealing component to start the drainage process. The liquid level detector records the change of liquid level over time during the drainage process. By analyzing the data of liquid level changes, the siphon performance of the sewage pipe can be obtained. The observation window and scale on the surface of the test chamber help the testers to more intuitively view the water level changes inside the test chamber. The test chamber is equipped with an inlet valve to fix the inlet water level and ensure that the water level can be stably controlled during the test. The outlet sealing component at the bottom of the sewage pipe can be driven to rotate to cover the sealing baffle at the bottom outlet of the sewage pipe, thereby controlling the start time of the siphon process. This facilitates the acquisition of stable and reliable test data and brings convenience to the pipeline testing.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
