Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a water meter with a multi-level sealing and leak-proof component. Background Technology

[0002] A water meter is an instrument that measures water flow, mostly by cumulative flow. It is generally divided into two categories: volumetric water meters and velocity water meters. The internal structure of a water meter, from the outside in, consists of three main components: the casing, the sleeve, and the inner core. During the water flow recording process, water flows through the meter via a flow pipe, and the flow rate is then displayed on the instrument panel. Currently, water meters need to be connected to external pipelines to extend the water transmission distance and facilitate water usage for users.

[0003] Modern water meters have evolved to include smart water meters with electronic components. The control box of a smart water meter contains many electronic components, which makes the sealing requirements more stringent. Currently, traditional smart water meter control boxes often use a set of flat sealing gaskets for sealing. After long-term use, the flat sealing gaskets age, crack, and shrink, leading to water leakage at the connection points of the smart water meter control box.

[0004] Therefore, it is necessary to invent a water meter with a multi-stage sealing and leak-proof component to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water meter with a multi-level sealing and leak-proof component. The multi-level sealing of the water meter is achieved through the cooperation of the main water pipe and the multi-level sealing mechanism, so as to solve the problem that the traditional smart water meter control box in the prior art often uses a set of flat sealing gaskets for sealing. After long-term use, the flat sealing gaskets age, crack and shrink, resulting in water leakage at the connection position of the smart water meter control box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water meter with a multi-level sealing and leak-proof assembly, including a main water pipe, both ends of which are provided with multi-level sealing mechanisms. The multi-level sealing mechanism includes connecting water pipes located at both ends of the main water pipe. An upper reinforcing ring is fitted above the connecting water pipe, and a lower reinforcing ring is fitted below the connecting water pipe, with the upper and lower reinforcing rings bolted together. A connecting flange is fixedly connected to the outer wall of the connecting water pipe on the side closest to the main water pipe. A protruding connecting seat is fixedly connected to the outer wall of the connecting water pipe. The protruding connecting seat and the connecting flange are both wrapped inside the upper and lower reinforcing rings. The upper and lower reinforcing rings wrap and reinforce the connection between the connecting water pipe and the main water pipe to seal it.

[0007] Preferably, the main water pipe has an oblique groove on the side near the connecting water pipe, and the surface of the oblique groove has several sets of connecting grooves. The interior of the connecting groove is filled with a raised sealing gasket, which is fixedly connected to the inner wall of the connecting water pipe. The cooperation between the connecting flange and the connecting groove forms a multi-layer seal, thereby enhancing its leak-proof function.

[0008] Preferably, the inner walls of both the upper and lower reinforcing rings are fixedly connected to an anti-corrosion rubber shell, and the inner wall of the anti-corrosion rubber shell is fixedly connected to an anti-deformation sealing gasket, thereby enhancing the anti-corrosion function of the structure.

[0009] Preferably, a reinforcing layer is provided on one side of the anti-deformation sealing gasket, and several sets of elastic balls are fixedly connected inside the reinforcing layer. The cooperation between the anti-deformation sealing gasket and the reinforcing layer reduces the deformation caused by thermal expansion and contraction, thereby preventing the internal parts of the multi-level sealing mechanism from being corroded by air.

[0010] Preferably, a smart water meter is fixedly connected to the top of the main water pipe, and two sets of filter screens are installed on the inner wall of the main water pipe. A traction cable is provided on the outer side of the filter screen. The filter screen filters impurities in the water flow to prevent them from damaging the smart water meter.

[0011] Preferably, the traction cable is fixedly connected to the inner wall of the main water pipe, and a rotating wheel is rotatably connected to the outer side of the traction cable. Several sets of force-bearing blocks are fixedly connected to the surface of the rotating wheel. The rotating wheel is driven to rotate by the impact of the water flow on the force-bearing blocks, thereby reducing the impact of the water flow on the filter screen.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. By cooperating with the main water pipe and the multi-level sealing mechanism, the connecting water pipe and the main water pipe are first installed together, so that the connecting groove and the raised sealing gasket cooperate with each other to form a multi-level seal to prevent water leakage. The upper and lower reinforcing rings are connected by bolts, which presses the raised docking seat and the connecting flange. The gap between the upper and lower reinforcing rings, the raised docking seat and the connecting flange are filled by the anti-corrosion rubber shell, thereby reducing the infiltration of external air and preventing the raised sealing gasket from losing its sealing performance due to aging.

[0014] 2. Through the cooperation of the filter screen, rotating wheel and force-bearing block, the rotating wheel is installed inside the main water pipe by the traction cable. The cooperation of the rotating wheel and the force-bearing block dissipates the energy of the water flow, thereby reducing the impact force of the water flow on the filter screen. The filter screen filters impurities in the water flow, preventing the water meter from malfunctioning due to excessive impurities. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The water meter shown includes a multi-stage sealing and leak-proof assembly, comprising a main water pipe 1. Both ends of the main water pipe 1 are equipped with multi-stage sealing mechanisms 2. Each multi-stage sealing mechanism 2 includes connecting water pipes 201 located at both ends of the main water pipe 1. An upper reinforcing ring 202 is fitted above the connecting water pipe 201, and a lower reinforcing ring 203 is fitted below the connecting water pipe 201, with the upper reinforcing ring 202 and the lower reinforcing ring 203 bolted together. A connecting flange 205 is fixedly connected to the outer wall of the connecting water pipe 201 on the side closest to the main water pipe 1, and a protruding connecting seat 204 is fixedly connected to the outer wall of the connecting water pipe 201. Both the raised mating seat 204 and the connecting flange 205 are enclosed within the upper reinforcing ring 202 and the lower reinforcing ring 203. The upper and lower reinforcing rings 202 and 203 enclose and reinforce the connection between the connecting water pipe 201 and the main water pipe 1, sealing it. The main water pipe 1 has an oblique groove on the side near the connecting water pipe 201, and several sets of connecting grooves 206 are formed on the surface of the oblique groove. The connecting grooves 206 are filled with raised sealing gaskets 207, which are fixedly connected to the inner wall of the connecting water pipe 201. The connection flange 205 and the connecting grooves 206 cooperate to form multiple... The multi-layer sealing mechanism enhances its leak-proof function. Corrosion-resistant rubber shells 5 are fixedly connected to the inner walls of both the upper reinforcing ring 202 and the lower reinforcing ring 203. Anti-deformation sealing gaskets 9 are fixedly connected to the inner walls of the corrosion-resistant rubber shells 5. The corrosion-resistant rubber shells 5 enhance the corrosion resistance of the structure. A reinforcing layer 10 is provided on one side of the anti-deformation sealing gasket 9. Several sets of elastic balls are fixedly connected inside the reinforcing layer 10. The cooperation between the anti-deformation sealing gasket 9 and the reinforcing layer 10 reduces deformation caused by thermal expansion and contraction, thereby preventing corrosion of the internal parts of the multi-layer sealing mechanism 2 by air. The main water pipe 1 connects to the multi-layer sealing mechanism. The cooperation of the sealing mechanism 2 firstly involves installing the connecting water pipe 201 and the main water pipe 1 together, thereby allowing the connecting groove 206 and the raised sealing gasket 207 to cooperate with each other, forming a multi-layer seal to prevent water leakage. The upper reinforcing ring 202 and the lower reinforcing ring 203 are bolted together, thereby pressing the raised docking seat 204 and the connecting flange 205. The anti-corrosion rubber shell 5 fills the gaps between the upper reinforcing ring 202, the lower reinforcing ring 203, the raised docking seat 204, and the connecting flange 205, thereby reducing the infiltration of external air and preventing the raised sealing gasket 207 from losing its sealing performance due to aging.

[0025] Refer to the instruction manual appendix Figure 1-5A smart water meter 3 is fixedly connected to the top of the main water pipe 1. Two sets of filter screens 4 are installed on the inner wall of the main water pipe 1. A traction cable 6 is set on the outer side of the filter screens 4. The filter screens 4 filter impurities in the water flow to prevent them from damaging the smart water meter 3. The traction cable 6 is fixedly connected to the inner wall of the main water pipe 1. A rotating wheel 7 is rotatably connected to the outer side of the traction cable 6. Several sets of force blocks 8 are fixedly connected to the surface of the rotating wheel 7. The water flow impacts the force blocks 8, causing the rotating wheel 7 to rotate, thereby weakening the impact of the water flow on the filter screens 4. Through the cooperation of the filter screens 4, the rotating wheel 7 and the force blocks 8, the rotating wheel 7 is installed inside the main water pipe 1 by the traction cable 6. The cooperation of the rotating wheel 7 and the force blocks 8 performs energy dissipation work on the water flow, thereby reducing the impact force of the water flow on the filter screens 4, and filtering impurities in the water flow through the filter screens 4 to prevent the water meter from malfunctioning due to excessive impurities.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5 After the main water pipe 1 and the multi-level sealing mechanism 2 are installed, the main water pipe 1 and the multi-level sealing mechanism 2 work together to first install the connecting water pipe 201 and the main water pipe 1, so that the connecting groove 206 and the raised sealing gasket 207 cooperate to form a multi-level seal to prevent water leakage. The upper reinforcing ring 202 and the lower reinforcing ring 203 are bolted together, thus pressing down the raised docking seat 204 and the connecting flange 205. The anti-corrosion rubber shell 5 fills the gaps between the upper reinforcing ring 202, the lower reinforcing ring 203, the raised docking seat 204, and the connecting flange 205, and strengthens the anti-corrosion rubber shell 5. The corrosion protection function of this structure utilizes the cooperation between the anti-deformation sealing gasket 9 and the reinforcing layer 10 to reduce deformation caused by thermal expansion and contraction, thereby preventing the internal parts of the multi-level sealing mechanism 2 from being corroded by air and reducing the infiltration of external air, which would cause the raised sealing gasket 207 to lose its sealing performance due to aging. When the main water pipe 1 is in use, the rotating wheel 7 is installed inside the main water pipe 1 by the traction cable 6. The rotating wheel 7 and the force-bearing block 8 cooperate to receive the impact of the water flow and rotate, thereby dissipating the energy of the water flow and reducing the impact force of the water flow on the filter screen 4. The filter screen 4 filters impurities in the water flow, preventing the water meter from malfunctioning due to excessive impurities.
