[0024] The sealing structure for preventing external water vapor from penetrating into the schematic rotor water meter, refer to Figures 1 to 2 The sealing structure for preventing external water vapor from penetrating into the schematic rotor water meter, refer to

[0025] Specifically, as shown in Figure 1 The transparent cover 20 includes a buckle part 201, a raised part 202, an observation part 203, and an open cavity 204. The open cavity 204 is located at one end of the transparent cover 20 with the buckle part 201. The counting device 10 is arranged in the open cavity 204. The material of the transparent cover 20 is glass or transparent resin. In addition, the copper cover 30 wraps the buckle part 201 and closes the opening of the open cavity 204. The material of the copper cover 30 is copper.

[0026] It should be noted that by increasing the overall height of the transparent cover 20, the open cavity 204 of the transparent cover 20 can provide space for accommodating the counting device 10. At this time, the copper cover 30 only serves as a member for closing the open cavity 204. Compared with the prior art, the copper cover 30 provides space for accommodating the counting device 10, and the transparent cover 20 closes this space. The glass or transparent resin material of the present application is lower, and the copper material is less. Since the cost of glass and transparent resin is lower than that of copper, the overall manufacturing cost of the sealing structure for preventing external water vapor from penetrating into the rotor water meter is lower, and the copper usage is less, and the cost is lower.

[0027] Further, in order to improve the sealing performance of the connection between the transparent cover 20 and the copper cover 30, as shown in Figure 1 The sealing structure for preventing external water vapor from penetrating into the schematic rotor water meter, refer to

[0028] Specifically, as shown in Figure 2As shown, the copper cover 30 comprises a bottom part 301, a vertical cylinder part 302 and a necking part 303, the vertical cylinder part 302 is located at the side of the bottom part 301, the center of the bottom part 301 extends a predetermined distance away from the side of the counting device 10 and forms an extension 304, the necking part 303 is obtained by bending the end of the vertical cylinder part 302 away from the bottom part 301 to the center axis of the bottom part 301 by a predetermined angle.

[0029] It should be noted that the bottom part 301, the vertical cylinder part 302 and the necking part 303 together form an open placement cavity 305, by setting the extension 304, the upper magnetic steel member of the counting device 10 can be placed in the space of the extension 304 and closer to the upper magnetic steel on the impeller shaft of the rotary water meter; after placing the counting device 10 and the sealing member 40 in the placement cavity 305, the top of the vertical cylinder part 302 is bent to the center axis of the bottom part 301 by a predetermined angle to obtain the necking part 303 and abut against the outside of the sealing member 40, at the same time, the inside of the sealing member 40 abuts against the buckle part 201 of the transparent cover 20, so as to fix the copper cover 30 on the transparent cover 20 and fix the position of the sealing member 40.

[0030] Further, in order to improve the sealing effect, as shown in Figure 2 As shown, the sealing member 40 comprises a horizontal section 401, a vertical section 402 and a bending section 403, the top and bottom surfaces of the horizontal section 401 abut against the bottom surface of the bottom part 301 and the buckle part 201 respectively, the two side walls of the vertical section 402 abut against the side walls of the vertical cylinder part 302 and the buckle part 201 respectively, and the two sides of the bending section 403 abut against the necking part 303 and the buckle part 201 respectively.

[0031] It should be noted that, as shown in Figure 1 and Figure 2As shown, the anti-ambient water vapor penetration sealing structure of the rotor water meter further comprises a counting seat 50, which is provided with an annular gap 501 at one end of the copper sealing cover 30. During installation, the sealing member 40 is first placed in the placement cavity 305, and then the counting seat 50 is placed in the placement cavity 305, and the horizontal section 401 is inserted into the annular gap 501 and abuts against the bottom wall and side wall of the annular gap 501. Then, the counting device 10 is installed on the counting seat 50, and then the buckle part 201 of the transparent cover 20 is inserted into the area between the counting seat 50 and the vertical cylinder part 302. It should be noted that at this time, the closing part 303 has not been formed, i.e., only the bottom surface part 301 and the vertical cylinder part 302 exist at this time. Then, the top of the vertical cylinder part 302 is bent to form the closing part 303, and the two sides of the bent section 403 abut against the closing part 303 and the buckle part 201, respectively.

[0032] Further, in order to facilitate the positioning of the sealing member 40, the bottom surface part 301 is provided with an annular protrusion 3011, and one end of the horizontal section 401 away from the vertical section 402 abuts against the annular protrusion 3011. During installation, the horizontal section 401 of the sealing member 40 abuts against the annular protrusion 3011, so that after the counting seat 50 is placed in the placement cavity 305, the horizontal section 401 of the sealing member 40 is inserted into the annular gap 501 and abuts against the bottom wall and side wall of the annular gap 501. Compared with the prior art, this has the advantage of facilitating assembly and positioning. Figure 2

[0033] Further, in order to facilitate the pre-fixing of the sealing member 40, the intersection of the horizontal section 401 and the vertical section 402 is provided with a plurality of through holes 4011, and the area between the connection of the bottom surface part 301 and the vertical cylinder part 302 and the sealing member 40 is in communication with the through holes 4011.

[0034] It should be noted that when the sealing member 40 is placed in the specified position of the placement cavity 305, i.e., the sealing member 40 is placed in the copper sealing cover 30, and the bottom surface part 301 contacts the horizontal section 401 and the vertical cylinder part 302 contacts the vertical section 402, the operator can inject glue into the through holes 4011 and fill the gap between the sealing member 40 and the intersection of the horizontal section 401 and the vertical section 402 with the glue, thereby improving the sealing member 40 and achieving the pre-fixing of the sealing member 40.

[0035] It should be further noted that after the glue is injected into the through holes 4011, the through holes 4011 are not completely filled with the glue. After the glue solidifies into a solid, the operator can remove the copper sealing cover 30 from the transparent cover 20, and then the sealing member 40 is fixed in the copper sealing cover 30.​Figure 2 A water absorbing member 4012 is arranged in each through hole 4011.

[0036] It is to be noted that the water absorbing member 4012 includes but is not limited to sponge or water absorbing particles. By arranging the water absorbing member 4012 at the end of the through hole 4011 close to the glass cover, even if a small amount of water vapor seeps from the gap between the transparent cover 20 and the sealing member 40, it can be easily absorbed by the water absorbing member 4012 and slowly evaporated after a long time.

[0037] In summary, the anti-external water vapor penetration sealing structure of the rotor type water meter based on the embodiments of the present application is illustrated, which provides the anti-external water vapor penetration sealing structure of the rotor type water meter with the advantages of less copper consumption, lower cost, easy assembly and positioning, etc.

[0038] It is worth mentioning that in the embodiments of the present application, the anti-external water vapor penetration sealing structure of the rotor type water meter is simple in structure and does not involve complex manufacturing processes and expensive materials, which has high economic efficiency. At the same time, for the manufacturers, the anti-external water vapor penetration sealing structure of the rotor type water meter provided by the present application is easy to produce and has low cost, which is more conducive to controlling the production cost and further conducive to product promotion and use.
