DETAILED DESCRIPTION
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3 The present invention provides an embodiment of a drip-proof water meter, comprising a housing 1, with an inlet pipe 2 and an outlet pipe 6 symmetrically arranged on one side of the outer wall of the housing 1, and a drip-proof component provided on the inner wall of the housing 1 to prevent dripping. The outer walls of the inlet pipe 2 and the outlet pipe 6 are both provided with sealing components to improve the sealing performance at the connection between the inlet pipe 2 and the outlet pipe 6 and the pipe 3.
[0027] The anti-drip assembly includes a diversion pipe 17, which is installed on the inner wall of the outer casing 1. A baffle 4 is installed on one side of the inner casing 1, and a baffle 5 is installed on the other side. A pressure chamber 26 is located between the baffle 4 and the baffle 25. A support plate 7 is fixedly connected to one side of the outer wall of the baffle 4. An impeller 8 is installed on the upper surface of the support plate 7, rotating under the push of water flow. It is connected to a counting device through a transmission mechanism to measure the water flow. A one-way inlet 9 is opened on the inner wall of the support plate 7. A support cylinder 28 is fixedly connected between the baffle 4 and the baffle 5. A sliding column 27 is slidably connected to the inner wall of the support cylinder 28. A spring 13 is fixedly connected to one side of the inner wall of the support cylinder 28. When the sliding column 27 slides to the appropriate position, the spring 13 rebounds and causes the limiting block 14 to engage with the limiting groove 15, thereby limiting the sliding column 27. One end of the spring 13 is fixedly connected to the limiting block 14. The limiting groove 15 is opened on the outer wall of the sliding column 27. The spring 26 is sleeved on the outer wall of the sliding column 27. A diversion port 11 is opened on one side of the sliding column 27 and the support cylinder 28. A diversion port 22 is opened on the other side of the sliding column 27 and the support cylinder 28. They are located on both sides of the diversion pipe 17 and the support cylinder 28. When the two are aligned, the water flow is guided to the impeller 8 for metering and directly to the outlet pipe 6, respectively. A diversion port 11 is opened on the upper side of the outer side of the baffle 14. An inlet 10 is opened on the lower side of the outer side of the baffle 14.
[0028] Specifically, water enters the pressure chamber 26 after entering the inlet pipe 2. When the water pressure in the pressure chamber 26 is sufficient, it pushes the diversion pipe 17 to compress the second spring 16, causing the diversion pipe 17 and the sliding column 27 to slide. After the sliding column 27 is in place, the limiting block 14 enters the limiting groove 15 under the action of the first spring 13 to achieve the limiting. At this time, part of the water flows through the first diversion port 11 to push the impeller 8, and the other part flows through the second diversion port 12 to the outlet pipe 6. When dripping occurs, the water pressure cannot push the diversion pipe 17, and the impeller 8 does not rotate, thus avoiding mismeasurement under small flow rates.
[0029] Referring to Figures 1-5 The sealing assembly comprises a sealing gasket 20 arranged on the inner wall of the water inlet pipe 2 and the water outlet pipe 6, a connecting ring 23 fixedly connected to the outer wall of the water inlet pipe 2 and the water outlet pipe 6, a protruding block 19 slidingly connected to the inner wall of the connecting ring 23, a connecting ring 18 fixedly connected to the outer wall of the protruding block 19, a sealing gasket 22 arranged on the inner wall of the connecting ring 23, and an expansion ring 21 attached to the surface of the sealing gasket 22. Under the fastening of the connecting ring 18 and the connecting ring 23, the sealing gasket 20 and the sealing gasket 22 are further combined to improve the sealing performance of the connection part and prevent water leakage. The expansion ring 21 is attached to the surface of the sealing gasket 20. The connecting ring 18 and the connecting ring 23 are fixedly connected to the outer wall of the connecting block 24. The connecting block 24 is threadedly connected to the bolt 25. The connecting ring 18 is fixedly connected to the pipeline 3. The limiting block 14 is slidingly connected to the inner wall of the limiting groove 15. The limiting block 14 is used for limiting the sliding column 27. One end of the sliding column 27 is fixedly connected to the upper surface of the shunt pipe 17. The sliding column 27 is used for driving the shunt pipe 17 to slide. One end of the spring 16 is fixedly connected to the upper surface of the shunt pipe 17. The other end of the spring 16 is fixedly connected to the inner wall of the supporting cylinder 28. The supporting cylinder 28 is arranged above the pressure chamber 26. The outer wall of the sealing gasket 20 is arranged on the inner wall of the connecting ring 23. The outer wall of the expansion ring 21 is arranged on the inner wall of the connecting ring 23. The protruding block 19 is used for extruding the sealing gasket 20.
[0030] Specifically, the connecting ring 18 on the pipeline 3 is aligned with the connecting ring 23 on the water inlet pipe 2 or the water outlet pipe 6, and the connecting blocks 24 of the two are corresponded. Then the bolt 25 is penetrated through the inner wall of the connecting block 24 and is tightly fixed. During the fixing process, the protruding block 19 of the connecting ring 18 extrudes the sealing gasket 20 on the inner wall of the water inlet pipe 2 or the water outlet pipe 6. At the same time, the sealing gasket 22, the expansion ring 21 and the sealing gasket 20 are closely attached to each other. Under the fastening pressure of the connecting ring 18 and the connecting ring 23, the water inlet pipe 2 and the water outlet pipe 6 are tightly sealed with the pipeline 3 at the connection part, preventing water leakage.
[0031] Working principle: when a kind of anti-dripping water meter needs to be used, when water flow enters from inlet pipe 2, water flow enters the support plate 7 below through inlet 10, part of the water flow enters the pressure chamber 26, when the water pressure in the pressure chamber 26 reaches a certain degree, the water flow will push the shunt pipe 17 to compress the spring 16, when the shunt pipe 17 moves to the appropriate distance, the shunt pipe 17 left and right two shunt openings 11 and 12 will be aligned with the shunt openings 11 and 12 on both sides of the support cylinder 28, since the shunt pipe 17 moves also drive the sliding column 27 to slide, when sliding to the appropriate distance, the limit block 14 is back by spring 13 into the limit slot 15, realize the limit of sliding column 27, when the sliding column 27 is limited, part of the water flow pushes the impeller 8 to rotate to realize the conventional metering, finally through the one-way water outlet 9 outside the inlet 10, another water flow flows into the outlet pipe 6 through the shunt opening 12, when dripping occurs, the pressure of water flow is difficult to reach the impact of shunt pipe 17 to make spring 16 shrink, so the impeller 8 will not rotate, realize anti-dripping;
[0032] In addition, when installing, the connecting ring 18 on the pipe 3 is aligned with the connecting ring 23 on the inlet pipe 2 or the outlet pipe 6, and the connecting block 24 is fixed by the bolt 25. During the connection process, the protruding block 19 extrudes the sealing gasket 20, and at the same time, the sealing gasket 22, the expansion ring 21 and the sealing gasket 20 are mutually attached, under the fastening action of the connecting ring 18 and the connecting ring 23, the sealing of the connection between the inlet pipe 2, the outlet pipe 6 and the pipe 3 is realized, and water leakage is prevented.
[0033] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
