Technical Field

[0001] The utility model relates to the technical field of water flow meters, in particular to a water flow meter with good sealing performance. Background Art

[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. The development of water meters has a history of nearly two hundred years. When selecting the specifications of a water meter, you should first estimate the size and flow range of the flow rate used under normal circumstances, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice. To ensure the accuracy of the water meter, the water meter must be calibrated regularly.

[0003] When existing water flow meters measure flow, backflow may occur, causing flow measurement errors. It is necessary to improve the sealing mechanism of the flow meter to prevent overflow and backflow and achieve accurate flow measurement.

[0004] In view of the above problems, a water flow meter with good sealing performance is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a water flow meter with good sealing performance, which solves the problem that when measuring flow, the existing water flow meter in the background technology may have backflow causing flow measurement error, and it is necessary to improve the sealing mechanism of the flow meter to prevent overflow and backflow and achieve accurate flow measurement.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water flow meter with good sealing performance, comprising a water flow tube, a flow rotation mechanism fixedly arranged inside the water flow tube, a flow meter mechanism sealed at the upper end of the water flow tube, the water flow tube comprising a circumferential flow tube, a partition fixedly arranged inside the circumferential flow tube, the flow rotation mechanism comprising a rubber filling layer fixedly arranged inside the circumferential flow tube, an internal frame engaged with the rubber filling layer, the flow meter mechanism comprising a lower plate fixedly arranged inside the circumferential flow tube, an upper plate fixed to the upper end of the lower plate, a filling block connected to one side of the lower plate, and a rotating water supply component rotatably arranged inside the lower plate and the filling block.

[0008] Preferably, a water outlet baffle is protrudingly provided on one side of the partition close to the water outlet pipe.

[0009] Preferably, the flow rotation mechanism further comprises a flow meter fixedly arranged inside the built-in frame, and the flow meter measures the number of rotations of the rotating water delivery component.

[0010] Preferably, a flip cover is rotatably provided on one side of the built-in frame, and the flip cover is used to protect the flow meter.

[0011] Preferably, the lower plate, the upper plate and the filling block are fixed to each other, and a plurality of oblique openings are provided on the side surface of the lower plate.

[0012] Preferably, a water outlet groove is provided on one side of the upper plate corresponding to the water outlet pipe.

[0013] Preferably, the rotating water supply assembly includes a turntable rotatably arranged inside the flow pipe, and the upper end of the turntable is provided with multiple groups of connected straight rotating plates and arc-shaped rotating plates.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides a water flow meter with good sealing performance. Through the coordinated arrangement of a water flow tube and a flow rotation mechanism, a partition inside the flow tube is arranged between the lower plate and the upper plate, thereby realizing the separation of the inner and outer sides of the lower plate and the upper plate to prevent water overflow. This preliminarily solves the problem that when existing water flow meters measure flow, it is necessary to improve the sealing mechanism of the flow meter to prevent water overflow and backflow.

[0016] 2. The utility model provides a water flow meter with good sealing performance. Through the coordinated arrangement of the flow rotating mechanism and the flow meter mechanism, the rubber filling layer realizes sealing isolation between the diverter tube and the built-in frame. The water transported in the lower plate can drive the rotating water supply component to rotate, transport the water upward, and flow out from the upper plate. The number of rotations of the rotating water supply component helps the flow rotating mechanism to measure the water volume. The filling block is sealed and arranged between the diverter tube and the lower plate to prevent backflow.

The flow meter mechanism 3 includes a lower plate 31 fixedly arranged inside the circumferential flow tube 11, an upper plate 32 fixed to the upper end of the lower plate 31, and a filling block 33 connected to one side of the lower plate 31. A rotating water supply component 34 is rotatably arranged inside the lower plate 31 and the filling block 33.

[0027] Specifically, the partition 111 inside the diverter tube 11 is arranged between the lower plate 31 and the upper plate 32 to separate the inner and outer sides of the lower plate 31 and the upper plate 32 to prevent water overflow. The rubber filling layer 21 realizes sealing isolation between the diverter tube 11 and the built-in frame 22. The water transported in the lower plate 31 can drive the rotating water supply component 34 to rotate, transport the water upward, and flow out from the upper plate 32. The number of rotations of the rotating water supply component 34 helps the flow rotation mechanism 2 to measure the water volume. The filling block 33 is sealed and arranged between the diverter tube 11 and the lower plate 31 to prevent backflow.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combine Figure 2-Figure 6 The water flow pipe 1 includes a water supply pipe 12 and a water outlet pipe 13 fixedly arranged on both sides of the diversion pipe 11. A filter screen 121 is fixedly arranged inside the water supply pipe 12. The filter screen 121 filters the water flow. The water supply pipe 12 supplies water to the diversion pipe 11, and the water outlet pipe 13 supplies water to the outside.

[0031] A water outlet baffle 112 is protruding from one side of the partition 111 close to the water outlet pipe 13. The water outlet baffle 112 is at the same height as the lower plate 31, thereby achieving water flow sealing of the lower plate 31, so that water can only be transported to the water outlet pipe 13 after passing through the upper plate 32 from the lower plate 31.

[0032] The flow rotation mechanism 2 also includes a flow meter 23 fixedly arranged inside the built-in frame 22. The flow meter 23 measures the number of rotations of the rotating water supply component 34.

[0035] Combine Figure 4 and Figure 5 The lower plate 31, the upper plate 32 and the filling block 33 are fixed to each other. A plurality of oblique openings 311 are opened on the side of the lower plate 31. The oblique openings 311 are opened obliquely. The design of this structure enables the water flow transported in the oblique openings 311 to promote the rotation of the rotating water supply component 34.

A plurality of connected straight rotating plates 342 and curved rotating plates 343 are arranged at the upper end of the turntable 341. The turntable 341 rotates under the drive of the water flow in the oblique mouth 311, thereby driving the straight rotating plates 342 and curved rotating plates 343 arranged in a circular array to rotate. The straight rotating plates 342 and the curved rotating plates 343 are connected, and the curved rotating plates 343 are arranged in an arc shape to facilitate the upward conveyance of water.
