Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] Please refer to Figures 1-3 The shell body 1 is a hollow structure with upper and lower openings, and the upper end of the shell body 1 is provided with a flange positioning edge 15 around the outer periphery, and the flange positioning edge 15 is provided with an annular groove 14 with an outer depth and an inner shallow and a positioning hole, and a double-layer sealing ring 62 is placed in the annular groove 14;

[0032] The shell body 1 is a hollow structure with upper and lower openings, and the upper end of the shell body 1 is provided with a flange positioning edge 15 around the outer periphery, and the flange positioning edge 15 is provided with an annular groove 14 with an outer depth and an inner shallow and a positioning hole, and a double-layer sealing ring 62 is placed in the annular groove 14;

[0033] Specifically, as Figure 4 The annular groove 14 includes a first groove 141, an isolation section 142 and a second groove 143 arranged in turn from inside to outside, wherein the depth of the first groove 141 is less than that of the second groove 143, and the isolation section 142 is arranged at the groove connection of the first groove 141 and the second groove 143, playing a smoothing role. When external water vapor does not isolate the corresponding sealing ring of the second groove 143, it enters the first groove 141 along the isolation section 142, and the first groove 141 again isolates the water vapor, achieving the purpose of sealing.

[0034] like Figure 5 As shown, the cover 2 includes a cover flange that matches the flange positioning edge 15. The cover flange and the flange positioning edge 15 have the same number of positioning holes and are fixed together by bolts. The radial end face of the cover 2 is provided with an external groove 22, and a sealing ring 61 is provided in the external groove 22.

[0035] The upper inner surface of the shell cover 2 is provided with an internal groove 23, and a sealing ring 61 is provided in the internal groove 23. A transparent glass 3 is embedded below the internal groove 23, and an aluminum clamping ring 4 is provided below the transparent glass 3. The aluminum clamping ring 4 is connected by threads to clamp the transparent glass 3.

[0036] In this embodiment, the shell body 1, shell cover 2, transparent glass 3, and aluminum clamping ring 4 are all circular, so that the shell body 1, shell cover 2, transparent glass 3, and aluminum clamping ring 4 match each other, thereby facilitating installation;

[0037] To further explain, the sealing ring 61 and the double sealing ring 62 are used to achieve the sealing function, and the transparent glass 3 allows the inside of the shell body 1 to be directly observed from the outside; the lower outer cylindrical side of the shell body 1 is provided with a first wire outlet hole 11, a second wire outlet hole 12 and a third wire outlet hole 13, respectively, through which the instrument connection wires inside the shell body 1 are connected;

[0038] The lower opening of the cable outlet base 5 is the welding outlet for the electromagnetic water meter sensor. In this embodiment, the lower opening of the cable outlet base 5 is welded together with the electromagnetic water meter sensor outlet, thereby achieving a complete seal. Figure 6 As shown, the outlet base 5 and the shell body 1 are fixedly connected by bolts. The overflow port 51 is set on the outside of the threaded ring. When water vapor enters, it first isolates the water vapor through the overflow port 51. A protrusion is set at the connection between the outlet base 5 and the shell body 1, which serves to isolate the water vapor a second time.

[0039] Specifically, the inner cylindrical surface of the cover 2 is provided with internal threads, and the outer cylindrical surface of the aluminum clamping ring 4 is provided with external threads, which match the internal threads. The purpose of this design is to gradually compress the transparent glass 3 and the O-ring 61 through the threads of the aluminum clamping ring 4, thereby achieving a seal on the cover.

[0040] Specifically, the shell cover 2 is connected with the shell body 1 through a screw rod, the end surface of the shell body 1 and the radial surface of the shell cover 2 are both provided with notches 14, 22 and sealing rings 61, 62, the sealing ring 61 of the shell body 1 is pressed by the shell cover 2, and the sealing ring 62 of the shell cover 2 is pressed by the shell body 1, so that the double-layer sealing structure effectively prevents external water and moisture from entering, thereby realizing the full sealing of the shell body, ensuring that the electronic components in the shell body are not damaged, and solving the serious problem that the electromagnetic water meter cannot work normally due to water entering the shell body.

[0041] Specifically, the inner cavity of the shell body 1 is filled with sealing glue, and it should be noted that the height of the sealing glue needs to be higher than the first wire outlet hole 11, the second wire outlet hole 12 and the third wire outlet hole 13 during the time of filling, so that external water and moisture can be prevented from entering the cavity of the shell body 1, thereby achieving a sealing effect, and also smoothly connecting the cable.

[0042] Specifically, the shell body 1, the shell cover 2 and the wire outlet base 5 are all made of 304 stainless steel.

[0043] The waterproof converter shell body of the electromagnetic water meter realizes the complete isolation of the internal electronic circuit of the electromagnetic water meter converter from external water and moisture, realizes complete sealing, reaches the IP68 waterproof level, and can ensure that the electromagnetic water meter can work underwater for a long time.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

[0045] Finally, the above is only a preferred embodiment of the present application and is not used to limit the present application, 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.
