Description

Technical Field

[0001] The utility model relates to the field of vertical water meters, in particular to a horizontal spiral top-inlet vertical water meter case. Background Art

[0002] Currently, the water flow direction of vertical water meters in China is generally bottom-in, top-out, with the water inlet at the bottom and the water outlet at the top. This is determined by the structural characteristics of the water meter movement: water enters from the bottom of the movement, driving the impeller to rotate, and then flows out from the top. With the development and advancement of water supply and heating technologies, some users are demanding top-in, bottom-out vertical water meters or heat meters. To address this problem, some water meter manufacturers have used the existing bottom-in, top-out housing and installed an improved movement to create a top-in, bottom-out water meter, such as the CN206362387U vertical top-inlet water meter. However, field measurements have shown that such meters suffer from high pressure drop, low sensitivity, and large errors at low flow rates. Furthermore, the use of a new movement significantly increases production costs, making them less practical. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figures 1 to 4 As shown, the housing of the horizontal spiral top-inlet vertical water meter includes a metering cavity 1, a horizontal cavity 2, an inlet pipe 3 and an outlet pipe 4, wherein:

[0030] An inner ring 11 is provided within the metering cavity 1, dividing the metering cavity 1 into a water inlet chamber 12 at the bottom and a water outlet chamber 13 at the top. Water inlet 15 and water outlet 14 are respectively provided in the water inlet chamber 12 and the water outlet chamber 13 near the inner ring 11. One end of the horizontal cavity 2 is fixed to one side of the metering cavity 1, and the upper and lower sides of the other end are connected to the water inlet pipe 3 and the water outlet pipe 4, respectively.

[0031] In order to allow water to flow from the water inlet pipe 3 into the water inlet chamber 12, as shown in FIG. Figure 2 A spiral water dividing plate 5 is provided in the horizontal cavity 2, one end of the water dividing plate 5 is connected to the outer wall of the metering cavity 1, and the other end is connected to the closed end of the horizontal cavity 2, so that the water dividing plate 5 divides the horizontal cavity 2 into an inlet channel 21 and an outlet channel 22, wherein the two ends of the inlet channel 21 are respectively connected to the water inlet pipe 3 and the water inlet 15, and the two ends of the outlet channel 22 are respectively connected to the outlet pipe 4 and the water outlet 14.

[0032] Through the above technical solution, water flows into the water inlet channel 21 from the upper water inlet pipe 3, enters the water inlet chamber 12 from the water inlet 15 under the guidance of the water dividing plate 5, passes through the movement and enters the water outlet chamber 13, then flows into the water outlet channel 22 through the water outlet 14, and finally flows out from the water outlet pipe 4 under the guidance of the water dividing plate 5 to achieve metering.

[0033] The advantage of this solution is that the water inlet from above is guided to the water inlet chamber below through the spiral water distribution plate 5, and the water inlet and outlet directions are reversed without changing the movement, so that the vertical water meter can realize the upper water inlet function. Compared with the solution of improving the movement, the production cost is greatly reduced, and the water distribution plate 5 is spiral, with small pressure loss, and can adapt to most places.

[0034] It is worth mentioning that Figure 4 One end of the water dividing plate 5 connected to the metering cavity 1 is horizontal to match the internal structure of the current metering cavity 1, and the other end of the water dividing plate 5 is at an angle of 30-60° to the horizontal plane. On the one hand, it can effectively isolate the water inlet pipe 3 and the water outlet pipe 4, and on the other hand, it can reduce pressure loss and guide the water flow to turn.

[0035] It is understandable that since the water inlet and outlet only need to exchange positions up and down to realize the upper water inlet function, the number of spiral turns of the water distribution plate 5 can be set to half a turn to avoid excessive rotation of the water flow and increase in pressure loss.

[0036] It should be noted that, for the convenience of processing, both ends of the horizontal cavity 2 are connected, and the water dividing plate 5 is placed and welded from both ends, and then the sealing plate 6 is welded to the closed end of the horizontal cavity 2.

[0037] In order to reduce production costs, the horizontal cavity 2, the water inlet pipe 3 and the water outlet pipe 4 are all circular tubes, which can be directly processed using stainless steel pipes, and the water inlet pipe 3 and the water outlet pipe 4 are welded to the horizontal cavity 2.

[0038] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
