Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a partition device for a water meter case, and relates to a structure for preventing freezing of a water meter, a water stop valve, and the like.

[Conventional technology]

Conventionally, in order to prevent this type of water meter from freezing,
A structure has been adopted in which a heat insulating material is provided on the back side of the outer cover of the water meter housing in which the water meter is housed and on the inner circumferential wall of the water meter housing body.

[Problem that the invention attempts to solve]

In the above conventional structure, if a pebble or the like gets caught in the fitting part between the outer lid and the water meter housing body, a gap is created between the outer lid and the water meter housing body, and cold air enters through this gap. On the other hand, since the air at the bottom of the water meter casing is kept warm by geothermal heat, the air inside the casing generates vertical convection, which lowers the temperature inside the casing and can cause the water meter and water stop valve to freeze. It has certain drawbacks.

In order to prevent this phenomenon, the inside of the water meter housing is partitioned almost horizontally with a partition plate, and this partition plate blocks the convection of air inside the housing, and the water meter and water stop valve are placed in the correct position. A structure is adopted to prevent cold air from entering below the partition plate. However, the above structure has the disadvantage that it takes time and effort to remove and attach the partition plate during meter reading, and that an engaging stepped portion must be formed on the inner wall of the casing in order to attach the partition plate. In addition, since the water pipes are buried below the freezing depth of the region, the depth of the water meter is not constant, and the position of the engaging stepped part, which is fixed to the inner wall of the casing in advance, cannot be moved freely, so the meter does not have a constant depth. There is a problem in that extra space is created above the water container, and geothermal heat cannot be used effectively.

Therefore, a structure can be considered in which a fitting hole is formed in the middle partition plate to be press-fitted to the upper end of the water meter, and the middle partition plate is held in the water meter. The positional relationship of the water meter is not constant, and if the water meter fitting hole is enlarged accordingly, a gap will be created around the water meter, causing the problem of cold air entering under the partition plate and causing convection throughout the water meter. be.

The purpose of the present invention is to provide a water meter with a partition plate that is held in a water meter with a water meter fitting hole, and a frame that closes the gap between the partition plate and the inner peripheral wall of the water meter housing. , by reliably separating the convection of cold air and warm air inside the water meter housing, increasing the heat retention effect inside the water meter housing and preventing freezing of the water meter, water stop valve, etc. To provide a partitioning device for a water meter casing that can ensure the partitioning effect even if the positional relationship with the water meter is slightly different, can be easily and reliably mounted, and can be easily read.

[Means for solving problems]

The present invention consists of a partition plate formed from synthetic resin foam with a water meter fitting hole into which the upper end of the water meter fits, and an inner circumference smaller than the outer circumference of the partition plate. A frame body formed of a synthetic resin foam and having an outer periphery substantially equal to the inner periphery of the water meter housing body, and a frame body formed from a synthetic resin foam, and a water meter fitting of the inner partition plate that is closely fitted to the upper end of the water meter. It is characterized by comprising a water meter closing plate molded from synthetic resin foam that closes the gap between the hole and the upper end of the water meter.

[Effect]

In this invention, first, a water meter closing plate made of synthetic resin foam is press-fitted to the upper end of the water meter, and then the water meter fitting hole in the middle partition plate made of synthetic resin foam is inserted into the water meter fitting hole. Either the middle partition plate is fitted to the upper end of the water dispenser and placed on the closing plate, or the water dispenser fitting hole of the middle partition plate is first press-fitted to the upper end of the water dispenser, and then the water dispenser closure is fitted. By attaching the plate to the upper end of the water meter and placing it on the upper surface of the middle partition plate, the gap created in the water meter fitting hole of the middle partition plate is closed, and this middle partition plate The partition plate is mounted within the water dispenser housing by being held at the upper end of the water dispenser. Then, the gap between the partition plate and the inner circumferential wall of the water meter housing body is closed by placing a frame made of synthetic resin foam on the top surface of the partition plate, and the gap between the inner peripheral wall of the water meter housing is closed. It prevents the water meter, water stop valve, etc. from freezing by dividing convection, and forms an engaging step on the inner wall of the housing body even if the positional relationship between the water meter housing and the water meter is slightly different. A partition plate can be attached to the interior of the casing body without having to do so, and the meter of the water meter can be read by using the water meter fitting hole as a viewing window.
