Technical Field
[0001] The utility model relates to the technical field of water meters, in particular to a telescopic non-return bipolar water meter device. Background Art
[0002] As global freshwater resources become increasingly scarce, water meters are important tools for managing and monitoring freshwater resources. Accurate measurement and management of water consumption is particularly important.
[0003] The installation and maintenance of traditional water meters usually require the separate installation of ball valves, check valves, and water meters in sequence, and the connection of multiple water pipes to prevent backflow of tap water and water theft. However, this installation cost is high and the installation process is relatively complicated. For some old and improved residential buildings, this installation and maintenance method is subject to space constraints, resulting in low efficiency and high costs.
[0004] Based on the above reasons, the utility model designs a retractable check bipolar water meter device. By combining the ball valve and the check valve, it avoids the impact of excessive pipeline installation and the installation environment. The rear ball valve is connected to facilitate the owner to switch it on and off by himself. At the same time, combined with the remote communication device on the water meter, it realizes real-time transmission of water meter data without the need for meter reading. Summary of the Invention

By combining a ball valve with a check valve, the device avoids the impact of excessive pipe installation and the installation environment. The rear-connected ball valve is convenient for owners to open and close the device themselves. At the same time, combined with the remote communication device on the water meter, the device realizes real-time transmission of water meter data without the need for meter reading.

DETAILED DESCRIPTION
[0015] The present invention will now be further described with reference to the accompanying drawings.
[0016] See also Figures 1-2 The utility model provides a retractable check bipolar water meter device, in which a municipal water pipe 1 is connected to an external thread 3 through a branch pipe 2, the external thread 3 is connected to a valve body, a ball valve 5 is arranged in the valve body, a magnetic control lock 4 is arranged on the upper part of the valve body, the water outlet end of the valve body is connected to a retractable valve cap 6, the retractable valve cap 6 is connected to a retractable pipe 8, a check valve 9 is arranged in the retractable pipe 8, a clamping nut 7 is arranged on the outside of the retractable pipe 8, a flexible nut 10 is connected to the outside of the retractable pipe 8, the water outlet end of the retractable pipe 8 is connected to a water meter 11, and the water outlet end of the water meter 11 is connected to a flexible ball valve 12.
[0017] A pair of N-pole and S-pole magnets are arranged diagonally 180 degrees on the bipolar transmitting pointer 13 of the water meter 11 .
[0018] The water meter 11 is provided with a remote communication device, which can transmit the read data remotely.
[0019] Working principle:
[0020] The utility model does not require any additional operation when used. Before installation, first confirm whether the system medium is compatible with the utility model and confirm the installation position and direction. During installation, you only need to connect the external thread 3 to the municipal water pipe 1 through the branch pipe 2, then connect the union nut 10 to the water meter 11, adjust the telescopic pipe 8 to the appropriate length and position, and tighten the compression nut 7.
[0021] During normal water use, the pressure between ball valve 5 and the water supply pipe is high, opening check valve 9 to allow water to flow through. When water is not flowing, the pressures on both sides of ball valve 5 are close, causing the check valve 9 to close prematurely due to the tension spring, effectively isolating the water flow. Furthermore, when the pressure on the water supply side of ball valve 5 decreases further, check valve 9 can also prevent backflow. This combination of ball valve 5 and check valve 9 provides the same benefits as traditional installation methods, but with a simpler structure and lower costs.
[0022] When there is water flow impact, the bipolar pointer 6 on the water meter 11 located on the movement will rotate along with it. The pointer of the bipolar pointer 13 is diagonally 180 degrees, and is respectively installed with a samarium cobalt magnet with the N pole and S pole facing upward. The electromechanical sensor located above the fast-acting pointer 13 generates a double pulse signal when it senses the alternating changes of the N pole and S pole. The N pole and S pole are high and low levels 0 and 1 respectively. According to the four level states of 01, 10, 11, and 00, the forward and reverse water consumption of the water meter is accurately measured.
[0023] When the customer does not need to use it, he only needs to manually close the live ball valve 12 at the rear end.
[0024] The above are only preferred embodiments of the present invention and are intended to help understand the method and core concept of this application. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
[0025] This utility model comprehensively solves the problem of the existing technology that water meters cannot be installed through multiple pipe connections in traditional methods due to limited installation space in old houses. By combining a ball valve with a check valve, it effectively prevents the water meter from idling in both forward and reverse directions. At the same time, a bipolar pointer and a remote communication device are set in the water meter, which ensures that the water meter is not affected by ambient vibration and measurement accuracy, and eliminates the need for door-to-door meter reading. It is also convenient for users to turn it on and off by themselves. The device as a whole minimizes the use of pipes and the number of splicing connections, meeting the requirements of small spaces. At the same time, it reduces the overall production and installation costs, and is more convenient for maintenance and installation.
