Description

Technical Field

[0001] The utility model relates to the technical field of water meter structure design, and particularly relates to a vertical rotor cold water meter with a filtering function. Background Art

[0002] When a rotary water meter works, water flow tangentially impacts an impeller from the water inlet of the meter housing to make it rotate, and then the rotation speed of the impeller is continuously recorded through a gear reduction mechanism, so as to record the cumulative water flow passing through the water meter. During use, generally a filtering box with uniform sieve holes is used for filtering, which can only filter impurity particles with a larger volume, and it is not convenient to clean and replace the filter net. Content of the Utility Model

[0003] The purpose of the utility model is to provide a vertical rotor cold water meter with a filtering function that has a reasonable structure and reliable use, solve the problem that the filter net is not convenient to replace and clean, clean the filter net in time without affecting the operation of the water meter, ensure the filtering function, and also facilitate replacing the filter net with an appropriate aperture according to requirements.

[0004] The technical solution of the utility model is as follows:

[0005] A vertical rotor cold water meter with a filtering function includes a vertical rotor cold water meter body. The technical key points are that: two branch inlet pipelines are arranged at the water inlet of the vertical rotor cold water meter body, the lower ends of the two branch inlet pipelines are respectively fixedly connected with a filtering pipeline, the lower ends of the two filtering pipelines are connected with two outlets of a Y-shaped water inlet pipeline, a first control valve is arranged on each of the two branch inlet pipelines, a second control valve is arranged at each of the two outlets of the Y-shaped water inlet pipeline, a filtering component is arranged in the filtering pipeline, and both ends of the filtering pipeline are connected with the branch inlet pipeline and the Y-shaped water inlet pipeline by upper and lower flange plates.

[0006] For the above-mentioned vertical rotor cold water meter with a filtering function, the filtering component includes a supporting baffle and a filter net. The supporting baffle is arranged obliquely along the height direction of the filtering pipeline. The filter net is placed inside the upper end of the filtering pipeline. A water passing port is arranged at the upper part of the supporting baffle, and a positioning edge is arranged at the lower end. The positioning edge is fixedly connected with the inner wall of the filtering pipeline.

[0007] For the above-mentioned vertical rotor cold water meter with a filtering function, an impeller close to the water inlet is arranged on the vertical rotor cold water meter body.

[0008] For the above-mentioned vertical rotor cold water meter with a filtering function, threaded connection structures are respectively arranged at the end of the water outlet pipeline of the vertical rotor cold water meter body and the inlet of the Y-shaped water inlet pipeline.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The water inlet is connected to a filtering pipeline through two branch inlet pipelines respectively, and then the external pipeline is connected by a Y-shaped water inlet pipeline. When one filtering pipeline needs to be cleaned, the other filtering pipeline continues the filtering work to ensure the working efficiency of the water meter.

[0011] 2. A support baffle is arranged obliquely along the height direction of the filtering pipeline. Water flows through the water passing opening at its upper part, and then through the filter screen to the inner side of the water meter body. During this process, intercepted sediment and other sundries accumulate and precipitate in the space surrounded by the lower part of the support baffle and the inner wall of the filtering pipeline. When cleaning is needed, the filtering pipeline can be disassembled. At the same time, the filter screen can also be conveniently replaced according to customer requirements. In summary, this application solves the problems that the filter screen is not convenient to replace and clean. Without affecting the operation of the water meter, the filter screen can be cleaned in time to ensure the filtering function, and it is also convenient to replace the filter screen with an appropriate aperture according to requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be described in detail according to the accompanying drawings of the specification.

[0015] As Figure 1 shown, the vertical rotor cold water meter with a filtering function includes a vertical rotor cold water meter body 1, and the vertical rotor cold water meter body 1 is provided with an impeller 3 near the water inlet 4. Among them, the water inlet 4 of the vertical rotor cold water meter body 1 is provided with two branch inlet pipelines 5. The lower ends of the two branch inlet pipelines 5 are respectively fixedly connected to a filtering pipeline 8. The lower ends of the two filtering pipelines 8 are connected to the two outlets of the Y-shaped water inlet pipeline 14. The first control valves 6 are arranged on the two branch inlet pipelines 5. The second control valves 13 are respectively arranged at the two outlets of the Y-shaped water inlet pipeline 14. A filtering component is arranged in the filtering pipeline 8. The two ends of the filtering pipeline 8 are connected to the branch inlet pipeline 5 and the Y-shaped water inlet pipeline 14 by upper and lower flanges 7 and 12.

[0016] In this embodiment, the filtering component includes a support baffle 10 and a filter screen 9. The support baffle 10 is arranged obliquely along the height direction of the filtering pipeline 8. The filter screen 9 is built into the upper end of the filtering pipeline 8. The upper part of the support baffle 10 is provided with a water passing port 15, and the lower end is provided with a positioning edge 11. The positioning edge 11 is fixedly connected to the inner wall of the filtering pipeline 8. Threaded connection structures are respectively provided at the end of the water outlet pipeline 2 of the vertical rotor cold water meter body 1 and the inlet of the Y-shaped water inlet pipeline 14.

[0017] Working principle:

[0018] During use, the first control valve 6 and the second control valve 13 on the upper and lower sides of one filtering pipeline 8 are opened, and the first control valve 6 and the second control valve 13 on the upper and lower sides of the other filtering pipeline 8 are in a closed state. Water flow passes through an outlet of the Y-shaped water inlet pipeline 14, the corresponding filtering pipeline 8, and a branch inlet pipeline 5 and enters the vertical rotor cold water meter body 1, and then is discharged from the outlet pipeline 2 of the vertical rotor cold water meter body 1. During this process, the water flow tangentially impacts the impeller 3 to make it rotate, and then the gear reduction mechanism continuously records the number of revolutions of the impeller, so as to record the cumulative flow rate of the water flowing through the water meter. When it is necessary to clean the filtering pipeline 8 during the working process, switch to the other filtering pipeline 8 for work.
