Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cover for a meter unit used for water supply, and more particularly to a heat insulating cover for a meter unit installed on, for example, a pipe shaft of an apartment house.
[0002]
[Prior art]
Meters, stop cocks or check valves are installed as water supply equipment. In the case of a single-family house, these devices are usually buried at an appropriate location on the site. In the case of a high-rise apartment building, for example, a space called a pipe shaft is provided on the side wall of a stair landing. For example, it is arranged together with a gas meter or the like.
[0003]
However, since this pipe shaft has a small space, it is difficult to bring in an individual meter, a water stop cock, a check valve, etc., and connect it to the pipe already installed on the spot. Therefore, the applicant of the present application has proposed a meter unit in Japanese Patent Laid-Open No. 9-280919. That is, valves such as a meter and a water stopcock are integrated using a base and are to be placed in the pipe shaft in that state. The meter is configured to be easily detachable in consideration of later replacement.
[0004]
By the way, this pipe shaft itself is usually not subjected to any heat retention. Therefore, in cold districts and the like, water in the meter or the valve may freeze due to a decrease in temperature, especially at night in winter.
[0005]
[Problems to be solved by the invention]
This invention is made | formed in view of the said problem, and makes it the subject to provide the heat retention cover for meter units which is excellent in heat retention and can be attached easily.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is a mounting in which a meter, a stop cock, and a check valve are attached to the base along the longitudinal direction of the base and extend longitudinally at both ends of the base in the longitudinal direction. A heat insulating cover for the meter unit is provided, and the heat insulating cover includes a cover body having a space in which the meter unit can be received and a meter unit lid that covers the meter display unit and can be opened and closed. And a stop cock cover that covers the operation handle of the stop cock and can be opened and closed. And, in the cover body, an attachment part insertion hole through which the base attachment part is inserted from the inside of the cover body to the outside, and an end of the pipe connected to the water stopcock and the check valve can be inserted. A pipe insertion hole is provided.
[0007]
