Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating cover that serves the purpose of preventing freeze damage of a water meter or water stop valve.

Conventionally, as a thermos cover for water meter,
A water meter protective cover described in Publication No. 19419 is known, and its opening/closing lid plug is of a removable structure.

Therefore, if a conventional water meter heat insulating cover is installed on a water meter installed in a place with many pipes such as gas pipes, the lid may not open and close as expected.
This was causing a huge hindrance to meter reading work.

The present invention was developed in view of the above-mentioned drawbacks of the conventional water meter heat insulating cover, and it provides a water metering system that allows the lid to be opened and closed smoothly and without taking up much space, even in narrow spaces with existing gas piping. It provides a heat insulating cover for the container.

The water meter heat-insulating cover of the present invention comprises a pair of left and right semi-cylindrical mating molds 1 and 2 having storage parts 1a and 2a for storing the water meter M or a water stop valve, and an upper part of the mating molds 1 and 2. A circumferentially slidable opening/closing lid 3 attached to the formed recesses 1b, 2b, and band-shaped fastening members 4, 4 that fix the mating molds 1, 2 and serve as guides when the opening/closing lid 3 slides. The mating molds 1 and 2 have two circumferential band-shaped grooves 1g and 2g formed at intervals on their outer peripheral surfaces, and the two band-shaped grooves 1
A recess 1 into which the opening/closing lid 3 is attached between g and 2g.
b, 2b are provided, and openings S are formed in the recesses 1b, 2b, and the recesses 1b, 2b are provided with opening/closing lids 3 that are slidable in the circumferential direction to open and close the openings S.
At the same time, there are recesses 1 at both ends of the opening/closing lid 3.
Notches 3e, 3e are formed which are substantially flush with the belt-shaped grooves 1g, 2g when attached to the belt-shaped grooves 1g, 2b, and the fastening members 4, 4 are connected to the two belt-shaped grooves 1.
It is characterized in that it is wrapped so as to overlap the notches 3e, 3e of the opening/closing lid 3 within the areas g and 2g.

Next, a detailed description will be given based on an example shown in the drawings.

As shown in the drawings, the mating molds 1 and 2 have storage parts 1a and 2a for storing a water meter M or a water stop valve, and their outer surfaces are each formed in a circular arc. In the assembled state, the opening S is opened at the upper part and the shape is substantially horizontally cylindrical. Note that a is the mating surface. The mating mold 1 is fitted from the back side of the piped water meter M or water stop valve, and the mating mold 2 is fitted from the front side to secure the face.
Recesses 1b and 2b are formed in which the lid 3 is slid to open and close.

When the lid 3 is closed, the joint surface 1c with the mating mold 1 is formed with a concave groove 1d corresponding to the protrusion 3d provided on the joint surface 3c of the lid 3, thereby ensuring airtightness between the lid 3 and the mating mold 1. I have it. Furthermore, semicircular notches 1 are provided at both ends of the mating molds 1 and 2 to form pipe insertion holes 5.
h, 1h are formed, and a circular recess 1f, into which the end of the heat-insulating cylinder 6 that insulates the piping connected to the water meter M with a meter union or the like is fitted.
2f is formed. Band-shaped grooves 1g and 2 are provided in the tightening portions of the tightening members 4 and 4 for fixing the mating dies 1 and 2.
g is formed.

Next, since the opening/closing lid 3 slides approximately half the circumference on the outer peripheral surfaces of the mating molds 1 and 2, the curvatures of the recesses 1b and 2b of the mating molds 1 and 2 and the inner surface 3a of the lid 3 are made to have the same curvature. The openings S of the mating molds 1 and 2 are sealed.

The outer peripheral surface of the opening/closing lid 3 is provided with a plurality of finger grooves 3b, 3b, .

In addition, since the fastening member 4 also serves as a guide plate, notches 3e, 3e are provided at both left and right ends of the lid 3 to facilitate the rotation of the lid 3, and the lid 3 can be opened and closed from the mating molds 1 and 2. This prevents the lid 3 from coming off.

Materials for the above-mentioned mating molds 1 and 2 and the opening/closing lid 3 include polyethylene resin foam, urethane resin foam, styrene resin foam, polyethylene/styrene resin mixed foam, phenolic resin foam, and urea resin foam. Various foams having a heat insulating effect, such as glass wool rubber foam, can be used.

Next, the fastening member 4 is made of magic tape, a sheet plate,
The fastening member 4, which is made of a thin band-shaped body such as a stainless steel plate, is fitted into the band-shaped grooves 1g and 2g provided in the circumferential direction of the mating molds 1 and 2, and the overlapping portions of both ends of the fastening member are covered with adhesive tape or locking holes 4a. It is fastened and fixed by a method such as using the locking protrusion 4b.

When attaching the heat insulating cover of the present invention to a water meter M, fit the storage parts 1a and 2a of the mating molds 1 and 2 into the water meter M, and then attach the opening/closing lid 3 to the mating molds 1 and 2.
After fitting into the recesses 1b and 2b of the fastening member 4,
4 on both sides of molds 1 and 2 and set.

As mentioned above, the water meter heat insulating cover of the present invention has a structure in which the opening/closing lid 3 can be opened and closed by freely sliding with the fastening members 4 of the mating molds 1 and 2 as guides as described above. Even in situations where other piping such as gas is installed directly above the water heater or water stop valve, and the lid of the thermal cover cannot be opened or closed, the lid can be opened and closed smoothly, making it easy to stop work due to meter reading or water work. The water stop valve can be opened and closed very easily when pouring water, and the water meter or the water stop valve and the joints connecting them are protected by heat insulation, which is extremely effective.
