Abstract
Description
The present invention relates to a lower outer shell of the water meter, and more particularly, to form a double lower outer shell of the water meter to keep warm, and to be formed of a stainless steel, rust, and the inner surface is The present invention relates to a dual thermal water meter that allows the formation of a smooth water meter underbody.
In general, the water meter outer shell is formed of brass or the like to form a lower outer shell, and the lower inner shell includes an upper inner shell, an impeller and a shaft provided with a gear, a measuring needle, and a numerical display. Combine the installed lower inner shell and insert it into the lower inner shell of the water meter.When the upper outer shell is tightened, one water meter is assembled and the inlet and outlet pipes are placed on the inlet and outlet of the completed water meter. It is intended to be connected and used.
However, the casting of the water meter outer casing increases the mold cost and the material cost, and at the time of casting, the inner and outer surfaces of the water meter lower outer casing are not smooth, so the external surface has to be painted to increase the material cost and the process cost. In particular, the inner surface of the inner body of the lower water meter under which the many assembly parts are installed and operated is not smooth, and foreign matters are easily caught, resulting in poor water quality and poor thermal insulation.
In addition, since the material is brass, lead is eluted in tap water, which is harmful to the human body, and foreign matters are stuck on the inner surface. Therefore, gear operation is not smooth and quantity measurement is not accurate. During winter season, freezing problems occurred.
The present invention has been made in order to solve the conventional problems as described above, the outer surface of the water meter is configured to be formed of a material such as a smooth stainless steel, and configured to be formed in a double, the insulation is Its purpose is to provide a dual warm water meter that can form the outer shell of the water meter, which is well-made, rust-free, and smooth on its inner surface, which prevents foreign matter from sticking to it.
The present invention provides a water meter lower outer body,
½ shape of the lower outer shell is formed by a press mold, but two pairs of different sizes are formed. First, when the half of the small inner inner shell is welded along the weld in a state in which ½ of the small inner inner shell is in contact with each other, one lower inner shell is formed. A sieve is formed, and when the half of the lower outer shell is formed to be slightly larger in size, the lower outer outer shell is formed by facing each other on both sides of the lower inner shell, and the lower outer shell is formed in duplicate. ¼ shape of the lower outer body is formed in a press die, such as a state in which the lower outer body is formed, or only the inlet and outlet of the lower outer body are incised, and two pieces having different sizes are formed first. Expand and separate the quarter-shaped separating part of the lower outer shell body, separate the press mold located inside, and contact the separating part again. When the weld is formed, the inner inner shell of the small water meter is completed. The lower part is made of ¼ shape of the small outer shell body, after the mold has been separated by expanding and separating the ¼-shaped separating portion of the lower outer shell body, which is slightly larger in size, and has a separation portion formed above the inlet and the outlet port. When the inner outer shell is inserted from above and the welded portion is formed by contacting the ¼-shaped separator of the slightly larger outer shell, the lower outer shell of the water meter is formed, and the lower outer shell of the water meter is formed in duplicate, Between the inner shell and the lower outer shell is characterized in that consisting of a lower outer shell configured to form an air layer, a vacuum or a heat insulating material.
The present invention can increase the warming action of the water meter to prevent freezing of water meters occurring in the winter season, and the lower outer body can be formed into a press die, so that it can be manufactured using a stainless steel, etc., which does not require painting, so Since the surface is not rusted, foreign matters are not easily caught, and thus the water quality is improved, and since the painting work is not performed on the outer shell of the water meter, the material cost and the process cost can be reduced.
The technical problem achieved by the present invention and the practice of the present invention will be more apparent from the following preferred embodiments of the present invention. The following examples are merely illustrated to illustrate the present invention and are not intended to limit the scope of the present invention.
Hereinafter, the present invention will be described with reference to the accompanying drawings.
