Description

  The present invention relates to a water meter housing in which a water meter connected to a spiral water supply pipe is disposed in a water supply laid in a cold region.

  Conventionally, water supply pipes laid in cold regions have been buried deep in the ground to prevent freezing by using geothermal heat. For this reason, since the water meter connected to the water supply pipe is also disposed at a deep position in the ground, the water meter stored in the water meter housing having a relatively small inner diameter matched to the water meter. It was difficult to perform inspections or periodic exchanges using the Measurement Law.

  Therefore, by wrapping the inflow and outflow side water supply pipes connected to the water meter spirally in the water meter housing, the water meter is normally positioned at a deeper position than the freezing depth. When checking or replacing a water meter, it can be pulled up by the extension of a spiral water supply pipe connected to the water meter, so that the water meter can be inspected and replaced. A water supply pipe for water supply is known (for example, see Patent Document 1).

  However, since the inflow side and outflow side water supply pipes wound in a spiral shape are drawn out from the inside of the water meter housing, the water supply pipe curves in a direction substantially perpendicular to the direction opposite to the spiral winding direction. The water pipe is inserted into the water pipe insertion hole opened on the outer peripheral surface of the water meter housing, and is bent in the piping direction outside the water meter housing. It is not easy to pull out the water pipe by inserting it into the water pipe insertion hole of the water meter housing, and the cross section is easily deformed, for example, the water pipe becomes flat when the water pipe is bent. There were problems that adversely affected the flow rate and water pressure of tap water.

Therefore, a water supply pipe insertion hole opened at the lower end opening edge of the water meter housing is opened on the outer peripheral surface of the water meter housing, and the lead-out portion of the water pipe wound spirally is connected to the water meter housing. A method has been proposed in which the elastic plate and the hard plate inserted through the water supply pipe insertion hole opened at the lower end opening edge are fixed to the water meter housing and the water supply pipe is fixed (patent) Reference 2).

The problem to be solved is that, even in the water meter housing shown in Patent Document 2, the water supply pipe is substantially perpendicular to the direction opposite to the spiral winding direction in order to draw the water pipe from the inside to the outside of the water meter housing. It is necessary to bend it in the piping direction outside the water meter housing, and the water supply tube must be bent to the water meter housing. The present invention has been made in view of the above-described problems. The water supply pipe is bent in an S-shape near the water supply pipe insertion hole of the body, and the cross section of the water supply pipe is easily deformed, affecting the flow rate and water pressure of tap water. Thus, a water meter housing is provided in which a water supply pipe wound spirally can be easily pulled out without applying a load from the water meter housing.

  The water meter housing of the present invention has one end connected to the inflow side and outflow side water supply pipe connection portions of the water meter, and the other end portions of the two water supply tubes spirally wound in the vertical direction. A water meter housing that is led out from each of the water pipes and accommodates the water meter so that the water meter can be moved upward by a pull-out operation of a pull-up portion provided on one end of the water supply pipe. And a main body having a swelled portion for pulling out the water supply pipe with a water supply pipe insertion hole opened at the tip end surface at two locations in the middle of the outer peripheral surface, and an enlarged diameter portion for fitting the lower end of the upper portion of the main body is formed at the upper portion A lower part, a bottom part of the main body that closes the lower surface opening of the lower part of the main body, a frame having an outer diameter that is fitted into the upper surface opening of the upper part of the main body and substantially matches the outer diameter of the upper part of the main body, and is supported by the frame And an openable / closable lid that is installed on substantially the same surface as the ground surface, The swelled portion for pulling out the water supply pipe has a substantially spiral shape in plan view by sequentially bulging outwardly the arrangement part of the cross-section concave arc-like surface on which the other end part of the spirally curved water supply pipe is arranged toward the tip side.
