Abstract
Description
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.
SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the problems of the related art described above, and it is an object of the present invention to provide a waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type waterproof type And a liquid flow rate display device of a wet type water meter capable of clearly displaying a flow rate at the same time.
In addition, the present invention is configured such that the one-row numeric dial capable of interlocking with the reduction gear unit is installed therein, and the sealed housing, which is filled with the liquid-sealed medium through the injection port at one side thereof, is connected to the lower part of the display window of the main body frame as an independent component, The present invention is based on the problem of providing a liquid rod type flow rate display device of a wet water meter in which the media can be quickly and easily filled and assembled.
The present invention provides a flow rate display apparatus for a wet water meter for displaying a flow rate in conjunction with a reduced rotation of a reduction gear unit, the flow rate display apparatus comprising: a body frame provided at an upper portion of the reduction gear unit and having a display window; A flow rate display unit provided in the closed housing and interlocked with the reduction gear unit to rotate a numeric dial of one row to display a flow rate; And a liquefied medium filled and sealed inside the sealed housing provided with the flow rate display unit through an injection port.
According to a preferred aspect of the present invention, a lower portion of the display window of the main body frame is formed with a lower portion of the lower portion of the lower portion thereof.
According to a preferred aspect of the present invention, the closed housing includes a housing main body in which one end of a shaft of the flow indication unit is rotatably coupled, a side cover joined to the housing main body and rotatably coupled with the other end of the shaft of the flow display unit .
According to a preferred feature of the present invention, the hermetically sealed housing is made of a transparent synthetic resin material.
According to a preferred feature of the present invention, the injection port is closed by the engagement of the sealing plug after the filling of the liquid sealing medium.
According to a preferred feature of the present invention, the liquid medium is glycerin.
According to the liquid rod type flow rate display apparatus of the wet water meter according to the present invention, since the flow rate display unit capable of interlocking with the reduction gear unit in the closed housing is installed in a liquid-sealed state by the liquid seal medium, tap water does not flow into the flow rate display unit, It is advantageous that the foreign matter contained in the dial is interposed between the dials of the single row or deposited on the surface of the dial of the single row so that the failure can be prevented and the flow rate indication can be clearly displayed.
According to the liquid rod type flow rate display apparatus of the wet water meter according to the present invention, one row of numeric dials interlocked with the reduction gear unit is installed therein, and the liquid-sealed medium is injected through the injection port on one side, So that the liquid-tight filling operation and the entire assembly process of the liquid-sealed medium can be performed quickly and easily.
