The present invention relates to a flow rate display apparatus for a wet water meter, and more particularly, to a flow rate display apparatus for a wet water meter that displays a flow rate of tap water flowing through a wet water meter through a display window through a combination of one- To a flow meter of a water meter.

Generally, a water meter is a device for imposing a water rate by measuring the amount of tap water used for a certain period, which is installed in a house, a factory, a building, or the like where tap water is supplied.

Most of these meters can be divided into dry meter and wet meter. Here, the dry-type meter is configured such that a flow rate display device for measuring and displaying the flow rate is mounted outside the water meter to prevent water from flowing into the interior of the water meter during operation. In addition, the wet meter is equipped with a flow rate display device for measuring and displaying the flow rate, which is installed in the water meter and flows into the water meter during the operation, so that it can be manufactured in a small size and is widely used because it is relatively inexpensive.

In the conventional wet water meter, the tap water introduced from the inlet pipe enters the water forming section through the inflow hole, passes through the outflow hole and flows out to the outlet pipe, and rotates the impeller. The rotation of the impeller is transmitted to the speed reducer The flow rate of the tap water is displayed through the transparent window of the display due to the combination of the numeric dial of the flow rate display device which is transmitted to the reduction gears of the fisherman and finally rotated by the speed reducer fisher unit. .

As an example of such a wet water meter, Korean Utility Model Registration No. 20-0302092 (published on Mar. 24, 2003), a flow rate display device is mounted inside the outer shell, a glass plate is fixed to the upper side of the flow rate display device, And the flow rate display device, wherein the space portion is provided with a buffer member which is contracted in accordance with an increase in the volume of the water introduced into the outer shell.

However, in the case of the flow meter of the conventional wet water meter as described above, as the tap water flows into the inside of the water meter, the dust or foreign substances contained in the tap water are caught between the dials or deposited on the surface of the dial. There was a problem that it was not easy.

In order to overcome such a problem, a glycerin case having a housing shape in which a numeric dial interlocked by a reduction gear unit is incorporated is disclosed in Korean Utility Model Registration No. 20-0371057 (Dec. 29, 2004) And a glycerin filled in the inner space of the glycerin case and / or the space between the body frame and the transparent plate.

However, in the case of the flow meter of the conventional wet water meter as described above, it is easy to fill glycerin with water tightly in a narrow space of 3 mm or less formed between the inner space of the glycerin case and the transparent plate, There was a problem that it did not.
