Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, and in particular to an external drainage device for detecting the pressure of a tap water pipe. Background Technology

[0002] Water pipes, as crucial pipeline facilities for transporting tap water, are widely laid underground in cities and inside buildings. They bear the important mission of delivering treated water from water sources to various water points, aiming to meet people's daily water needs. After new pipelines are laid or after maintenance and renovation, pressure testing is required to ensure good pressure resistance and guarantee a safe water supply. When the water source changes or users report abnormal water quality, corresponding water quality tests are necessary to ensure that the water quality meets hygiene standards. Air vents play a role in releasing air from the pipes during water filling and operation, effectively preventing air from forming airlocks. To prevent interference with the normal flow of water and to prevent abnormal pressure fluctuations, pressure gauges can display the pressure value inside the water pipe in real time, helping staff to accurately grasp the current pressure status, promptly detect pressure abnormalities and take countermeasures to maintain stable operation of the water pipe. However, in actual use, air release valves and pressure gauges need to be replaced as needed, and the replaced parts are often left aside, which can easily lead to the loss of parts. Once used again, they are difficult to find, which not only delays the normal monitoring and maintenance process of the water pipe system, but may also force users to repurchase, thereby increasing costs and time costs, and causing many inconveniences and obstacles to the entire water pipe operation and maintenance work.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-5 This is the first embodiment of the present invention, which provides an external drainage device for tap water pipe pressure detection. The external drainage device for tap water pipe pressure detection includes a main component and a switching component. The two components work together to directly switch and quickly replace the air release valve and pressure gauge, avoiding random placement and loss of components, ensuring timely use, and making water pipe operation and maintenance efficient and smooth.

[0029] The main component 100 includes a water pipe 101, a faucet 102 fixed to one end of the water pipe 101, a valve 103 fixed to the top of the water pipe 101, an air release valve 104 fixed to the top of the valve 103, and a pressure gauge 105 provided on one side of the air release valve 104.

[0030] Water pipe 101 is used to transport water and ensure the normal flow of water. Faucet 102 is used to control the opening and closing of water flow and to take water as needed. Valve 103 mainly plays the role of regulating and cutting off the water flow in the water pipe. Air release valve 104 can release the air accumulated in the water pipe to avoid air blockage affecting the water flow. Pressure gauge 105 can display the pressure value in the water pipe in real time, so as to facilitate the monitoring of pressure. There are three water pipes 101. Water pipe 101 is fixed at the bottom of valve 103 and at one end of faucet 102. The three water pipes 101 are connected.

[0031] The switching component 200 is disposed on the venting valve 104 and includes a switching element 201. The switching element 201 includes a base 2011, which is fixed to the top of the valve 103. A compression ring 2012 is disposed inside the base 2011, and a movable ring 2013 is sleeved on the outside of the venting valve 104.

[0032] The vent valve 104 and pressure gauge 105 can be installed on top of valve 103 according to usage requirements via the base 2011. A sealing ring is fixed on top of the compression ring 2012. After the vent valve 104 and pressure gauge 105 are installed on the base 2011, the bottom of the two can be squeezed by the movement of the compression ring 2012. At this time, the sealing ring can be squeezed to ensure the sealing performance after installation. There are two movable rings 2013, which are respectively sleeved on the outside of the vent valve 104 and pressure gauge 105. The two can be switched by the movement of the movable rings 2013.

[0033] Example 2

[0034] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the switching component 200 also includes a moving part 202, which includes a first spring 2021. One end of the first spring 2021 is fixed to the bottom of the compression ring 2012, and the other end is fixed to the inner wall of the base 2011.

[0036] Before installing the vent valve 104 or pressure gauge 105, first move the compression ring 2012 to retract it into the base 2011. During this process, a squeezing force can be applied to the first spring 2021. After installing the vent valve 104 or pressure gauge 105, the force of the first spring 2021's rebound can drive the compression ring 2012 to squeeze the bottom of both.

[0037] Specifically, a slide bar 2022 is fixed to one side of the compression ring 2012, and a connecting plate 2023 is fixed to one end of the slide bar 2022.

[0038] The slide rod 2022 is slidably connected to one side of the base 2011. The slide rod 2022 can be moved by moving the connecting plate 2023. Then, the movement of the slide rod 2022 can cause the compression ring 2012 to retract into the base 2011.

[0039] Specifically, a connecting post 2024 is inserted into the bottom of the connecting plate 2023, and the connecting plate 2023 and the connecting post 2024 are movably connected. A positioning plate 2025 is fixed to one end of the connecting post 2024, and the positioning plate 2025 is fixed to one side of the vent valve 104.

[0040] When the connecting plate 2023 moves, it can move on the connecting column 2024, thereby supporting the connecting plate 2023 and preventing it from shifting during movement. The positioning plate 2025 can also support the connecting column 2024 and prevent it from shifting.

[0041] Specifically, a second spring 2026 is fixed to the bottom of the connecting plate 2023, and one end of the second spring 2026 is fixed to the top of the positioning plate 2025.

[0042] When the connecting plate 2023 moves, it can apply a compressive force to the second spring 2026. When the connecting plate 2023 is released, the rebound force of the second spring 2026 can drive the connecting plate 2023 back to its original position.

[0043] Example 3

[0044] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the switching component 200 also includes a connector 203, which includes a connecting rod 2031, and the connecting rod 2031 is fixed to one side of the movable ring 2013.

[0046] There are two connecting rods 2031, both fixed to one side of the movable ring 2013. By moving the connecting rods 2031, the movable ring 2013 can be moved, thereby completing the switching between the vent valve 104 and the pressure gauge 105.

[0047] Specifically, a positioning post 2032 is provided at the bottom of the connecting rod 2031. The positioning post 2032 and the connecting rod 2031 are rotatably connected by a rotating shaft. The positioning post 2032 is fixed to one side of the valve 103.

[0048] The positioning pin 2032 can support the connecting rod 2031 and prevent the connecting rod 2031 from shifting during rotation.

[0049] Specifically, a turntable 2033 is fixed to the bottom of the connecting rod 2031, and a positioning block 2034 is provided at the bottom of the turntable 2033.

[0050] Rotating the turntable 2033 will drive the connecting rod 2031 to rotate, thereby completing the switching. After the switching is completed, the turntable 2033 can be limited by engaging the positioning block 2034 with the turntable 2033.

[0051] Specifically, the bottom of the turntable 2033 is provided with a positioning groove 2034-1 corresponding to the positioning block 2034, and the positioning block 2034 is located in the positioning groove 2034-1.

[0052] The turntable 2033 can be rotated by engaging the positioning block 2034 and the positioning groove 2034-1. When it is necessary to release the limit on the turntable 2033 and switch the vent valve 104 or the pressure gauge 105, the limit on the turntable 2033 can be released by separating the positioning block 2034 and the positioning groove 2034-1.

[0053] Specifically, a handle 2035 is fixed to the bottom of the positioning block 2034, and the handle 2035 is fixed to one side of the connecting plate 2023.

[0054] The handle 2035 is sleeved on the outside of the positioning post 2032. The handle 2035 and the positioning post 2032 are movably connected. By moving the handle 2035, the positioning block 2034 and the positioning groove 2034-1 can be separated, releasing the limit on the turntable 2033. At the same time, the compression ring 2012 can be moved into the base 2011. Then, the vent valve 104 or pressure gauge 105 can be installed on the top of the base 2011. Then, by releasing the handle 2035, the compression ring 2012 can return to its original position and engage with the bottom of the two to complete the installation. At the same time, the turntable 2033 is limited again.

[0055] In use, firstly, moving the handle 2035 causes the positioning block 2034 to move and separate from the positioning groove 2034-1, which in turn causes the connecting plate 2023 to move. When the connecting plate 2023 moves, it can move on the connecting column 2024. At this time, a squeezing force can be applied to the second spring 2026. The movement of the connecting plate 2023 causes the slide rod 2022 to move. Then, the movement of the slide rod 2022 can cause the compression ring 2012 to retract into the base 2011.

[0056] Now, rotate the turntable 2033. The rotation of the turntable 2033 will drive the connecting rod 2031 to rotate, which will then drive the movable ring 2013 to move. The movement of the movable ring 2013 will drive the vent valve 104 or pressure gauge 105 to move to the top of the base 2011. Both the vent valve 104 and the pressure gauge 105 have slots at their bottoms. After moving them to the top of the base 2011, release the handle 2035. First, the rebound force of the second spring 2026 will drive the handle 2035 back to its original position, causing the positioning block 2034 and the positioning groove 2034-1 to engage and limit the turntable 2033. Then, the rebound force of the first spring 2021 will drive the compression ring 2012 to compress the bottom of both, thereby completing the installation and compressing the sealing ring to ensure sealing.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
