Description

Technical Field

[0001] This utility model relates to the field of water meter flow detection technology, specifically to an automatic flow detection system for large-diameter water meters. Background Technology

[0002] Currently, water meter testing primarily uses volumetric manual testing devices, which calculate the error by comparing the water flow reading on the meter with that on a standard container. This method requires highly skilled operators, as human error is easily introduced when comparing the meter reading with the standard container reading. Furthermore, to minimize human error when calibrating smaller flow rates, a larger total flow rate and a longer testing time are needed.

[0003] The specification of a prior art (publication number CN202511851U) for an automatic water meter high-flow detection device mentions that "a solenoid valve is installed at the inlet end of the device, and an electric control ball valve is installed at the outlet end; a standard water meter and a water meter under test are sequentially installed in the pipeline between the solenoid valve and the electric control ball valve; the output end of the controller is connected to the solenoid valve and the electric control ball valve respectively; the controller controls the opening and closing of the test water source through the solenoid valve, and the controller adjusts the flow rate of the test water source through the electric control ball valve; multiple photoelectric sensors are respectively installed directly above the standard water meter and the water meter under test to measure the flow rate of the standard water meter and the water meter under test; the output end of the photoelectric sensor is connected to the input end of the controller to upload the measured flow rate value to the controller." However, the water meters in the prior art suffer from large impacts and wear during the detection process due to the large water flow, making them difficult to maintain and durable. Furthermore, they are not easy to discharge residual sewage and residue separately, and are not flexible or practical for long-term use. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a large-diameter water meter flow rate automatic detection system is provided to solve the problems of existing water meters being subject to large impacts and wear during the detection process due to large water flow, making them difficult to maintain and durable, and also making it difficult to separately discharge residual sewage and residue, thus lacking flexibility and long-term practicality.

[0005] To achieve the above objectives, an automatic flow detection system for large-diameter water meters is provided, comprising a central pipe section, a left guide sleeve, and a lead screw. The central pipe section has an inlet on its left side, with the left guide sleeve fitted inside. The central pipe section has an outlet on its right side, with a right guide sleeve fitted inside. An insulation sleeve is provided on the outer surface of the central pipe section. A connecting rod is located in the middle of the upper part of the central pipe section, with a water meter head at its upper end. A flow detection probe is located at the lower part of the connecting rod, extending into the center of the central pipe section. A lower connecting pipe is located in the middle of the lower part of the central pipe section, with a lead screw movably mounted inside the lower connecting pipe.

[0006] Furthermore, a lower connecting pipe is provided at the lower part of the lower connecting pipe, and a sewage pipe is connected to the right side of the lower connecting pipe, and an electromagnetic control valve is installed on the sewage pipe.

[0007] Furthermore, the outer end of the left guide sleeve is provided with a flange, and the flange has multiple sets of screw holes, and the left guide sleeve is detachably connected to the water inlet.

[0008] Furthermore, the inner wall of the left guide sleeve is equipped with multiple sets of reinforcing ribs made of stainless steel, and the left guide sleeve is made of nitrile rubber. In addition, multiple sets of guide grooves are provided on the inner side of the left guide sleeve.

[0009] Furthermore, the right guide sleeve is detached from the outlet pipe, and the left and right guide sleeves are symmetrical about the center line of the middle pipe section, and the right guide sleeve and the left guide sleeve have the same structural configuration.

[0010] Furthermore, the upper end of the lead screw is provided with a sealing plug made of rubber, and the lower end of the lead screw is provided with a handwheel. The lead screw is movably connected to the bottom of the tube seat by a thread, and the lead screw can move up and down in the vertical direction.

[0011] The beneficial effects of this utility model are as follows: 1. The left guide sleeve in this utility model facilitates the proper guidance of water flow into the middle pipe section. The reinforcing ribs help to enhance the durability of the guide structure, making it less prone to deformation, and can also reduce wear on the inner wall of the middle pipe section, making it more durable.

[0012] 2. In this utility model, the left and right guide sleeves have the same structure, which facilitates the entry of water flow from one side and the exit of water flow from the other side. This makes assembly convenient and allows for quick disassembly and replacement, making it more convenient and practical.

[0013] 3. By turning the screw clockwise, the sealing plug can be moved downward in the lower connector until it is inserted into the pipe seat, which facilitates the discharge of residual liquid or residue in the middle pipe section through the lower connector and the drain pipe. Turning the screw counterclockwise, the sealing plug can be moved upward and inserted into the upper port of the lower connector, making it easier, more flexible and practical.

[0020] In this embodiment, a flange 20 is provided at the outer end of the left guide sleeve 2, and multiple sets of screw holes 21 are provided on the flange 20. The left guide sleeve 2 is detachably connected to the water inlet 11. Multiple sets of reinforcing ribs 22 are installed in the inner wall of the left guide sleeve 2. The reinforcing ribs 22 are made of stainless steel, and the left guide sleeve 2 is made of nitrile rubber.

[0022] In this embodiment, the right guide sleeve 3 is connected separately to the outlet pipe 12, and the left guide sleeve 2 and the right guide sleeve 3 are symmetrical about the center line of the middle pipe section 1. The right guide sleeve 3 and the left guide sleeve 2 have the same structural configuration.

[0023] As a preferred embodiment, the left guide sleeve 2 and the right guide sleeve 3 of this utility model have the same structure, which facilitates the entry of water flow on one side and the exit of water flow on the other side, making assembly convenient and quick to disassemble and replace, making it more convenient and practical.
