Description

  The present invention relates to a water meter unit that facilitates water meter attachment and removal operations.

  A water meter installed in a water supply is generally stored in a water meter box in a united state connected to a valve such as a water stop cock or a check valve. This water meter is obliged to be replaced at regular intervals based on the Measurement Law, and many water meters are replaced every day. Therefore, it is important to facilitate the replacement work of the water meter.

  Here, as shown in Patent Document 1, the connection between the water meter and the valve is such that the end face of the water meter with an open / close opening is butted against the end face of the valve with an open water inlet, and the end faces are joined by a joint such as a union nut. It is often done by fastening.

  However, if the connection between the water meter and the valve is made in this way, the inside of the water meter box that houses the water meter and the valve is narrow, so that the operation of the joint is difficult. Also, even if this joint is loosened, there is no room at both ends of the water meter unit, making it difficult to put in and take out the water meter. Thus, the conventional water meter unit has a problem in work.

  Also, in condominiums such as apartments and apartments, the installation space is limited, so a compact water meter unit is required. However, since this conventional water meter unit requires a space for operating the joint between the water meter and the valve, the installation interval between the water meter and the valve is wide and the installation space is large.
