Technical Field

[0001] The utility model relates to the field of flow detection devices, and more specifically to a water volume detection device for water balance testing. Background Art

[0002] Water balance testing is to strengthen the scientific management of water use to achieve maximum water conservation and rational water use. It involves all aspects of water use unit management and also shows strong comprehensiveness and technicality.

[0003] In the prior art, when conducting a water balance test, there will be certain impurities in the water. These impurities will cause wear to the worm gear inside the turbine flowmeter under the action of the water flow. The existing solution is to add a filter to the pipeline to filter the impurities, but the filter is often installed at the entrance of the pipeline and needs to be attached to the inner wall of the pipeline, which makes it very inconvenient for subsequent staff to replace the filter.

[0004] Therefore, in order to solve the above problems, a water consumption detection device for water balance test is proposed. Utility Model Content

[0015] 3. Beneficial effects

[0027] Example:

[0028] See also Figure 1 - Figure 4 A water consumption detection device for a horizontal balance test comprises an outer sleeve 1 and a flow meter 2. An inner tube 3 is arranged inside the outer sleeve 1. Two positioning grooves 31 are penetrated at the outer edge of the inner tube 3 near one end of the flow meter 2. The two positioning grooves 31 are symmetrically distributed on the outside of the inner tube 3. A filter tube 4 is arranged at one end of the inner tube 3 near the flow meter 2. Two card grooves 41 are penetrated at the outer edge of the filter tube 4. The positions of the two card grooves 41 correspond to the positions of the two positioning grooves 31 one by one. A rotating buckle 5 is rotatably connected inside the positioning groove 31. A card block 51 is fixedly connected to the bottom surface of the rotating buckle 5. The card block 51 is carded with the card groove 41.

[0029] When the filter tube 4 is removed from the filter housing 1, the filter housing 1 is easily broken and the filter 4 is easily broken.

[0030] See also Figure 1 - Figure 4 A plurality of No. 1 threaded holes 11 are formed through the edge of one end of the outer sleeve 1, and a plurality of No. 2 threaded holes 32 are formed through the edge of one end of the inner tube 3. The number of the plurality of No. 1 threaded holes 11 is the same as the number of the plurality of No. 2 threaded holes 32.

[0031] Specifically, the positions of the plurality of No. 1 threaded holes 11 correspond to the positions of the plurality of No. 2 threaded holes 32 one by one, the internal threads of the plurality of No. 2 threaded holes 32 are connected with bolts 6, and the inner tube 3 is fixedly connected to the outer tube 1 by the plurality of bolts 6 arranged thereon.

[0032] In this solution, the No. 1 threaded hole 11 and the No. 2 threaded hole 32 are evenly distributed on the flanges of the outer sleeve 1 and the inner tube 3, respectively. The outer sleeve 1 and the inner tube 3 are slidably connected without the bolts 6 for fixing. After the rest of the inner tube 3 except the flange is completely placed inside the outer sleeve 1, the staff can rotate the inner tube 3 to align the No. 1 threaded hole 11 and the No. 2 threaded hole 32 one by one, and then the bolts 6 can be installed in the No. 1 threaded hole 11 and the No. 2 threaded hole 32, so as to fix the inner tube 3 and the outer sleeve 1, which can facilitate the staff to disassemble and assemble the outer sleeve 1 and the inner tube 3, and can also ensure the stable connection between the outer sleeve 1 and the inner tube 3 when performing a horizontal balance test.

[0033] See also Figure 1 - Figure 4A filter screen 42 is fixedly connected to one end of the filter tube 4 close to the flow meter 2. In this solution, the filter screen 42 is used to filter impurities in the water entering the outer sleeve 1 and the inner tube 3. When performing a water balance test, water enters from the flange connection between the outer sleeve 1 and the inner tube 3, and then enters the filter tube 4. The impurities therein are intercepted and filtered by the filter screen 42. The filtered water is then passed through the flow meter 2 for flow detection. Through the filtering of the filter screen 42, it can effectively prevent the impurities in the water from causing wear to the flow meter 2, thereby increasing the service life of the flow meter 2.

[0034] See also Figure 1 - Figure 4 A sealing ring 7 is fixedly connected to the edge of one end of the filter tube 4 close to the flow meter 2.

[0035] Specifically, a mounting groove 12 is formed on the inner wall of the outer sleeve 1 , and the sealing ring 7 is arranged inside the mounting groove 12 .

[0036] In this solution, the sealing ring 7 is made of rubber, which has a certain elasticity. When the inner tube 3 slides in the outer tube 1, the sealing ring 7 is squeezed and contracted. After the sealing ring 7 enters the installation groove 12, the sealing ring 7 will expand outward and fit into the inner wall of the installation groove 12. When performing a horizontal balance test, it can effectively prevent water from leaking from the connection between the outer tube 1 and the inner tube 3, thereby improving the sealing of the device and making the detection result of the flow meter 2 more accurate.

[0037] Working principle: Before conducting the horizontal balance test, the staff first puts the filter tube 4 into the end of the inner tube 3 with the positioning groove 31, and turns the rotating buckle 5 to make the clamping block 51 and the clamping groove 41 engage. Then the staff puts the inner tube 3 into the outer sleeve 1, and aligns the No. 1 threaded hole 11 and the No. 2 threaded hole 32, and then inserts the bolt 6 into the No. 1 threaded hole 11 and the No. 2 threaded hole 32 to install and fix the inner tube 3 and the outer sleeve 1;

[0038] When conducting a water balance test, the staff connects the external water source to the connecting ends of the outer sleeve 1 and the inner tube 3, and then turns on the water source switch. The water will first enter the filter tube 4, where the impurities are filtered by the filter screen 42, and then the water passes through the filter screen 42 and is detected by the flow meter 2.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
