The present invention relates to a water meter to prevent freezing, and in particular, the material of the transparent plate body on which the upper glass surface and the dial of the water meter, which are easily damaged in winter season, is mounted, but it is strong in impact resistance and cold resistance, and has a slight elasticity. It is replaced with a material that has a high temperature, and reinforces a well-damaged part in the water meter, so that the amount of water contained is reduced, and the volume of the expanded ice is reduced, thereby preventing freezing of the entire water meter and the diffusion and disappearance of glycerin. And freeze protection water meters.

Conventionally, both the outer shell of the water meter and the connecting pipe of both sides are made of metal, but the upper surface of the dial to allow the usage to be seen is formed by the glass surface, and when the tap water freezes during the winter season, it is pushed to the weak place as the volume increases. And the transparent plate installed at intervals of 1 mm just below the glass surface, and the dial mounting case where the glycerine is injected and the dial is used well.

The present invention was created to solve the problems of the above-described prior art, and reinforces so as not to damage the weak surface of the water meter, that is, the upper side of the glass surface and the lower side of the glass, which are not metallic, even in the cold winter season, Reduces the input amount (consumption amount) and the input time, and reinforces the outside and bottom side of the dial mounting case, so that the amount of water contained in the water meter is reduced, so that volume expansion is less even when the tap water freezes. The purpose is to prevent freezing.

The object of the present invention, instead of the glass surface of the water meter, using a polycarbonate sheet excellent in transparency, impact resistance and elasticity, and maintains performance even when temperature changes during freezing, the conventional transparent plate (AS material) is made of plastic ( After replacing with transparent plate made of ABS material, the polycarbonate sheet and plastic plate made of ABS material are closely attached to each other so that the transparency, impact resistance and elasticity can be doubled, and only at the periphery of the dial on one side of the plastic transparent plate. Equipped with a rubber O-ring, glycerin is added and stored only in the dial mounting case, reducing the amount of glycerin added. An elastic reinforcing piece is mounted on the outer side and the bottom of the dial mounting case to protect and reinforce the outer side and the bottom of the dial mounting case so as not to be damaged. By reducing the amount of water to be reduced, the volume expansion becomes smaller when water freezes, so that the glass surface portion, the transparent plate body portion, and the outer side and the bottom side of the dial mounting case are not damaged, and the volume expansion when the water in the water meter freezes. Absorption of parts to prevent partial damage or damage, so that there is no place where the water meter is freezing, the object of the present invention to achieve the freeze of the water meter is achieved.

In the water meter (1),

The polycarbonate sheet (3) is mounted instead of the glass surface (2) to be mounted on the dial (10), and the conventional transparent plate (AS material) 4 is replaced by a plastic transparent plate (made of ABS material) (5). However, only the peripheral part of the dial (10) on one side of the plastic transparent plate (5) forms the recessed portion (19), and the rubber O-ring (6) is inserted and installed, and then 1 mm between the polycarbonate sheet (3) and the plastic transparent plate (5). Closely mounted so that the space portion disappears, the fixing ring 26 is covered to be fixed to each other by ultrasonic welding, glycerin (8) is the dial 10 by the rubber O-ring (6) mounted on the peripheral portion of the dial (10) It is made to be stored and stored only in the peripheral part and the dial mounting case 9, and the outer side and the bottom side of the dial mounting case 9 are formed of an elastic material such as silicone (in the space part and the bottom side where the gear set 15 is not mounted). When forming the grooves (27) and the blade axle through hole (29) The elastic reinforcing piece 20 (to form a space portion 21 in the elastic reinforcing piece 20 to reinforce the elastic force, can be formed to accommodate the sponge, air, etc.) is formed and mounted, the lower inner shell body ( 12) Small fastening protrusions 28 and 28 'formed with fastening holes 24 and 24' are formed on both sides of the lower side, and fastening holes 24 and 24 'of the lower inner shell body 12 on both sides. Tightening screws 25 and 25 'for the elastic piece 22 having the fixing holes 23 and 23' formed therein (a space 21 'can be formed therein and a sponge, air, etc. can be accommodated). When the water contained in the water meter 1 freezes during the cold winter season, the transparent material portion formed so that the dial 10 is visible is not broken or damaged. This reduces the volume, thus reducing the expansion volume of water during freezing and absorbing and alleviating the volume expansion of critical areas. .

The operation of the present invention configured as described above is as follows.

Instead of the glass surface (2), a polycarbonate sheet (3), which is a material having excellent impact resistance, cold resistance, and elasticity, is installed on a plastic transparent plate (ABS material) (5) having a dial 10 and having impact resistance and elasticity, but 1 mm It is attached closely so that the space part is not formed, and even though the water inside the water meter freezes and expands in volume, the strength is doubled, and both materials can be slightly stretched and restored, so it is not damaged or damaged. do.

In addition, the grooves 19 are formed only at the periphery of the dial 10 on one side of the plastic transparent plate 5 so that the rubber O-rings 6 are mounted, and then the polycarbonate sheet 3 and the plastic transparent plate 5 are formed with a 1 mm space. By attaching it tightly so as not to be attached, (a conventional 1mm space is formed between the glass surface 2 and the transparent plate 4 as shown in FIG. 2, and the rubber O-ring 6 'is installed at the entire peripheral part of the transparent plate 4). When the glycerin (8) is injected into the dial mounting case (9), the glycerin (8) is filled in the 1 mm circular space between the glass surface (2) and the transparent plate (4). Glycerin (8) is only stored in the rubber O-ring (6) and the dial mounting case (9), thereby reducing the input amount and input time of the glycerin (8).

Further, when the elastic reinforcing piece 20 formed of silicon or the like on the outer side and the bottom face side of the dial mounting case 9 and having the mating recess 27 and the blade shaft passage hole 29 is mounted, the elastic reinforcing piece ( 20) serves to protect and reinforce the dial mounting case 9, which is easily damaged when water freezes, to mitigate volume expansion, thereby preventing damage from being damaged, and as much as the volume of the elastic reinforcement piece 20. Since the amount of water that can be accommodated in the water is reduced, the volume of water is generally increased by about 9% when the water is frozen, thereby reducing the amount of water received, thereby reducing the expansion volume.

In addition, since a little space is formed under the inner inner body 12 of the water meter 1, the fastening holes 24 and 24 'are formed on both sides of the lower inner body 12, and an elastic piece made of silicon or the like ( If the mounting and fixing 22), while the tap water inflow is constant, it serves to reduce the amount of water accommodated in the water meter (1) while reducing the expansion volume when the tap water is frozen, it is possible to absorb the volume expansion.

As described above, the material of the non-metallic part of the water meter, namely, the transparent plate part which makes the dial visible well, is formed of a special material that has undergone many experiments to prevent breakage and damage, and a large amount of leakage of tap water due to freezing of the water meter It prevents many inconveniences such as re-installation and re-installation work, and it is equipped with elastic reinforcing pieces and elastic pieces so as to protect and reinforce damaged parts and to absorb volume savings and volume expansion during expansion. It is a very useful invention that can prevent.
