[0002] Water meter is an instrument for measuring water flow. Most of them are cumulative flow measurement with nearly 200 years of development. They are generally divided into two categories: volumetric water meter and velocity water meter. They originated in the UK. When choosing the specifications of water meters, you should first estimate the size and flow range of the flow used under normal circumstances, and then choose the water meter with the specification that is closest to the value as the first choice. In the prior art, the application with publication number CN218724445U discloses a water meter shell, which includes an integrally formed upper end opening shell, the outer wall of the support retaining ring is close to the inner wall of the shell and welded, and the internal support retaining ring of the water meter shell is connected by direct welding, but the welding inside the shell requires the operator to be very skilled, and the support retaining ring cannot be guaranteed to be horizontal, which affects the water flow balance inside the shell, resulting in a high scrap rate; currently, there is a lack of a spliced ​​water meter shell with a more convenient support retaining ring fixation and a higher yield rate. Utility Model Content

[0003] The purpose of the utility model is to provide a novel spliced ​​water meter housing to solve the problem in the prior art that the welding of the supporting retaining ring is troublesome, thereby causing a high scrap rate.

[0004] The utility model is realized by the following technical solutions:

[0005] A novel spliced ​​water meter case comprises a shell, wherein the shell comprises an upper shell and a lower shell, a support retaining ring is provided at the bottom of the upper shell, and the support retaining ring is formed by bending inwardly through the bottom of the upper shell; the upper shell is fixedly connected to the lower shell, a water outlet is provided on the upper shell, and a water inlet is provided on the lower shell, the water outlet is connected to a water outlet channel, and the water inlet is connected to a water inlet channel.

[0006] Furthermore, an upper external threaded ring is provided on the top of the upper shell, and both the water outlet channel and the water inlet channel are provided with external threaded rings.

[0007] Furthermore, the inner diameter and outer diameter of the upper shell and the lower shell are the same, and the upper shell and the lower shell are vertically arranged and welded into one.

[0008] Furthermore, the support retaining ring is formed by inward stretching of the upper shell.

[0009] Furthermore, the support retaining ring is arranged horizontally to facilitate fixing the water meter movement.

[0010] Furthermore, the upper shell, the lower shell, the water inlet channel and the water outlet channel are all made of stainless steel, which has good corrosion resistance and a longer service life.

[0011] Furthermore, the water inlet and the water outlet are both semicircular, so that water flows more smoothly.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The support retaining ring of the utility model is formed by bending the bottom of the upper shell inwardly, so that the position and horizontal state of the support retaining ring inside the shell can be better adjusted, the manual welding cost is reduced, and the yield rate is improved.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the creation of the present invention.

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] Embodiment 1: A new type of spliced ​​water meter housing, such as Figure 1-Figure 3As shown, the shell comprises an upper shell 1 and a lower shell 2, the bottom of the upper shell 1 is provided with a support retaining ring 5, and the support retaining ring 5 is formed by bending the bottom of the upper shell 1 inwards; the upper shell 1 and the lower shell 2 are welded correspondingly, a water outlet 7 is provided on the upper shell 1, and a water inlet 8 is provided on the lower shell 2, a water outlet channel 4 is welded at the water outlet 7 of the upper shell 1, and a water inlet channel 3 is welded at the water inlet 8 of the lower shell 2. The support retaining ring 5 of the utility model is formed by bending the bottom of the upper shell 1 inwards, which can better adjust the position and horizontal state of the support retaining ring 5 inside the shell, reduce the cost of manual welding, and improve the yield rate.

[0023] Embodiment 2: A new type of spliced ​​water meter housing, such as Figure 1 As shown, the top of the upper shell 1 is welded with an upper external thread ring 6, and the water outlet channel 4 and the water inlet channel 3 are both welded with external thread rings 6, which are convenient for fixing and installing with the outside; the inner diameter and outer diameter of the upper shell 1 and the lower shell 2 are the same, and the upper shell 1 and the lower shell 2 are vertically arranged and welded as a whole; the support retaining ring 5 is formed by inward stretching of the upper shell 1; the support retaining ring 5 is arranged horizontally; the materials of the upper shell 1, the lower shell 2, the water inlet channel 3 and the water outlet channel 4 are all stainless steel, which has good corrosion resistance and longer service life. Figure 4-Figure 5 As shown, the water inlet 8 and the water outlet 7 are both semicircular, the cross-sections of the water inlet channel 3 and the water outlet channel 4 are elliptical, the connection between the water inlet channel 3 and the lower shell 2 completely covers the water inlet 8, and the connection between the water outlet channel 4 and the upper shell 1 completely covers the water outlet 7; the rest is the same as Example 1.
