Description

Technical Field

[0001] The utility model relates to the technical field of pipeline direct drinking water, in particular to a dual-channel direct drinking water water meter. Background Technique

[0002] The pipeline direct drinking water system takes municipal tap water or other centralized water supplies as raw water, and through a pretreatment system, a membrane treatment system, post-treatment, return water treatment and a water supply system, distributes through the main pipe and branch pipes to users to provide a direct drinking water supply system.

[0003] The length of the branch pipe from the direct drinking water supply riser to the household water tap is generally 3 - 5 meters. In large flat-floor houses, villas, commercial and public places, the length of the water supply branch pipes is relatively long, generally more than 6 meters. The direct drinking water in the supply riser circulates through the return pipe, while the water in the branch pipes is stationary. Various reasons (such as weekends or legal holidays in office buildings, or long periods when residents in residential buildings are away) may cause the direct drinking water to stay in the pipeline for too long, and the water quality will deteriorate. Currently, the general practice is that before taking direct drinking water, open the water tap to let the direct drinking water flow for a period of time to drain the stale water in the branch pipe, resulting in waste of water resources. Another solution is to use a water tap circulating pipeline to also regularly circulate the water in the branch pipes, which will cause problems in water consumption measurement. If only one water meter is installed, the actual water intake of the direct drinking water cannot be obtained. To know the actual water intake, it is necessary to measure the water volume of the water supply branch pipe and the return water branch pipe and calculate the difference between the two, which will increase the investment cost (two direct drinking water water meters need to be installed for one household) and the measurement accuracy problem.

[0021] The present utility model will be further described below in conjunction with the specification drawings and embodiments.

[0022] An embodiment of the present utility model provides a dual-channel direct drinking water meter.

[0023] Embodiment 1: A dual-channel direct drinking water meter includes a first inlet 1, a first outlet 2, a second inlet 3, a second outlet 4, a base 5, a first turbine 11, a second turbine 12, a first sensor 13, a second sensor 14, a first signal line 15, a second signal line 16, a control module 9 and a remote module 10. The base 5 is provided with a first inlet 1, a first outlet 2, a second inlet 3 and a second outlet 4. The first inlet 1, the first turbine 11 and the first outlet 2 form a first flow channel, and the second inlet 3, the second turbine 12 and the second outlet 4 form a second flow channel. A first sensor 13 is arranged at the position of the blade 63 of the first turbine 11, and a second sensor 14 is arranged at the position of the blade 63 of the second turbine 12. The first sensor 13 collects the rotation speed of the first turbine 11, and the second sensor 14 collects the rotation speed of the second turbine 12; the first sensor 13 and the second sensor 14 are connected to the control module 9 through the first signal line 15 and the second signal line 16.

[0024] Working principle: The control module 9 is internally provided with a battery power supply, and the battery supplies power to the sensor 7 and the control module 9. The control module 9 is internally provided with a remote transmission module and a calculation unit. During operation, the feed water enters the water meter from the first inlet 1. Under the action of the pressure difference, the first turbine 11 rotates, and the first sensor 13 detects the rotation speed n1 of the first turbine 11 and transmits it to the control module 9 through the first signal line 15. The return water enters the water meter from the second inlet 3. Under the action of the pressure difference, the second turbine 12 rotates, and the second sensor 14 detects the rotation speed n2 of the second turbine 12 and transmits it to the control module 9 through the second signal line 16. The calculation unit calculates the difference between n1 and n2 (n1 >= n2), N = n1 - n2. The rotation speed is proportional to the flow rate, and the flow rate Q = N * C (C is the calibration coefficient of the water meter). In this way, the flow rate difference between the feed water and the return water (the actual water consumption of the direct drinking water) is measured. The remote module 10 transmits the water meter flow rate signal to the control center, and the control center can calculate the water fee (water fee F = Q * P, P is the unit price of direct drinking water) through the charging system.

[0025] Embodiment 2: A dual-channel direct drinking water meter includes a first inlet 1, a first outlet 2, a second inlet 3, a second outlet 4, a base 5, a turbine 6, a sensor 7, a signal line 8, a control module 9, and a remote module 10. The base 5 is provided with a first inlet 1, a first outlet 2, a second inlet 3, and a second outlet 4. The first inlet 1 and the first outlet 2 form a first flow channel, and the second inlet 3 and the second outlet 4 form a second flow channel. A sensor 7 is arranged at the position of the turbine blade 63. The sensor 7 collects the rotation speed of the turbine 6; the signal line 8 of the sensor 7 is connected to the control module 9.

[0026] Working principle: The control module 9 is built-in with a battery power supply, and the battery supplies power to the sensor 7 and the control module 9. The control module 9 is built-in with a remote transmission module and a calculation unit. During operation, the feed water enters the water meter from the first inlet 1, and the return water enters the water meter from the second inlet 3. Since the cross-sectional areas of the flow channels are equal, if there is no water intake and the flow rates are the same, the flow velocities in the first flow channel and the second flow channel are the same. Also, since the turbine 6 is axisymmetric and centrosymmetric about the axis 61, the torque acting on the turbine 6 is the same in any case, and the turbine 6 does not rotate. When water is taken from a faucet, the return water flow rate is less than the feed water flow rate, the flow velocity in the return water flow channel is lower than that in the feed water flow channel, and the torque exerted by the water in the feed water flow channel on the turbine blade 63 is greater than the torque exerted by the water in the return water flow channel on the turbine blade 63. The turbine 6 rotates, and the sensor 7 detects the rotation speed N of the turbine 6 and transmits it to the control module 9 through the signal line 8. The rotation speed is proportional to the flow rate, and the calculation unit calculates the flow rate Q = N * C (C is the calibration coefficient of the water meter). In this way, the flow rate difference between the feed water and the return water (the actual water consumption of the direct drinking water) is measured. The remote module 10 transmits the water meter flow signal to the control center, and the control center can calculate the water fee (water fee F = Q * P, P is the unit price of direct drinking water) through the charging system.

[0027] In summary: A dual-channel direct drinking water meter, whose structure includes: a first inlet 1, a first outlet 2, a second inlet 3, a second outlet 4, a base 5, a turbine 6, a sensor 7, a signal line 8, a control module 9, and a remote module 10. When in use, the feed water enters the water meter from the first inlet 1, the return water enters the water meter from the second inlet 3, and at the same time, the rotation speed of the turbine 6 is transmitted from the sensor 7 to the control module 9. The remote module 10 transmits the water meter flow signal to the control center, and the control center can calculate the water fee through the charging system. One water meter realizes metering, which not only realizes the circulation of direct drinking water through the return pipe but also reduces the investment cost.
