Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support metal fitting (mounting metal fitting) for a fluidic gas meter having two connection mouths at the bottom, which are divided into a gas inlet side and a gas outlet side.

[0002]

2. Description of the Related Art As shown in FIG. 4, a membrane gas meter for city gas, which is small in size, has elbows 53, 54 attached to raised gas conduits 51, 52. In the base 55, 56 of the gas meter 50
, And the gas meter 50 is attached to the gas conduits 51 and 52 in a suspended state. 57 in the figure
Is a meter cock, and 58 is a test port.

[0003]

However, in the case of a fluidic gas meter, the width is 15 to 17 cm, the height is 15 to 18 cm, the depth is about 6 to 7 cm, and the connection base is present at the bottom. Therefore, it cannot be installed in the same manner as the above-mentioned membrane gas meter.

An object of the present invention is to provide a support fitting for properly and easily mounting a fluidic gas meter having a base at the bottom.

[0005]

The construction of the present invention is as follows.

A fitting unit is provided on the left and right sides of the upper surface, and a connection unit in which a meter cock is connected to one side of the fitting unit and a test port is connected to the other side of the lower part of the fitting unit. A support plate that is freely supported, a forward tilt adjustment screw that adjusts the forward tilt of the connection unit between the screw hole formed in the center of the bottom of the connection unit and the screw hole formed in the support plate, and the support plate. And a horizontal adjusting screw for supporting the supporting plate by a cam surface at one upper corner of the mounting plate, which horizontally supports the supporting plate, and a horizontal direction of the supporting plate by rotation of the cam surface. And a bottom support plate supporting the mounting plate, and a support fitting for a fluidic gas meter.

[0007]

The bottom support plate is fixed to the wall surface with the fixing screw, the mounting plate is placed on the bottom support plate and the mounting plate is also fixed to the wall surface, and the support plate is mounted on the mounting plate. At this time, one of the support plates is placed on the cam surface of the horizontal adjustment screw from above. Next, the connection unit is mounted on the support plate so as to be tilted forward, and a forward tilt adjusting screw is mounted between the connection unit and the support plate.

Next, the gas pipes are pulled up from below to the meter cock and the test port of the connection unit to connect them, respectively, and the fitting of the metal fittings is completed. After that, the fitting on the fluidic gas meter side is simply fitted into the fitting fitting opening on the connection unit. Fix the fluidic gas meter and the connection unit with screws as necessary.

The meter cock is closed during gas work after the fluidic gas meter or in the absence of gas for a long period of time, and the test port is opened for airtightness test.

When it is necessary to adjust the forward tilt and horizontal of the fluidic gas meter in the above-mentioned mounted state, the forward and backward tilt is adjusted by the forward tilt adjusting screw, and the support plate is leveled by the horizontal adjusting screw.

EXAMPLES Reference numeral 1 is a fluidic gas meter, 2,
2'is a mouthpiece, 3 is a connection unit, and the connection unit 3 has mouthpiece fitting ports 4, 4'formed on the left and right of the upper surface, and a meter cock 5 and a test port 6 are integrally attached to the lower part thereof.

Reference numeral 7 is a supporting leg formed on both sides of the bottom rear end of the connection unit 3, and 8 is a screw hole formed in the bottom portion.

Reference numeral 9 denotes a horizontal plane and an inverted L-shaped support plate formed by bending the horizontal plane downward at the rear end. A support shaft 10 is provided on the upper left and right sides of the rear end of the support plate 9 so as to project. The support leg 7 of the connection unit 3 is supported by the support shaft 10 so as to be tilted forward.

Reference numeral 11 is a gas conduit insertion hole, 12 is a screw hole, and a forward tilt adjusting screw 13 is attached between the screw hole 8 and the screw hole 12 of the connection unit 3 via an elastic spacer 8 ′. The screw 13 finely adjusts the front-back tilt.

Reference numeral 14 denotes a cam receiving groove formed on the right side of the lower edge of the support plate 9.

Reference numeral 15 is an L-shaped portion obtained by bending the rear end of the horizontal portion upward.
The mounting plate 15 is formed into a circular shape, and the mounting plate 15 is mounted on the wall surface at regular intervals via the spacers 16. The lower left corner of the support plate 9 is screwed at the upper left corner, and the cam surface 18 is fixed at the right corner. By engaging the cam receiving groove 14 with the cam surface 18 of the formed horizontal adjustment screw 17, the horizontal adjustment screw 1
This is a structure in which the horizontal direction of the support plate 9 is finely adjusted by rotating the cam surface 18 by rotating the cam surface 7. Reference numeral 19 is a support screw for the adjusting screw 17, which is screwed into the spacer 16 via the mounting plate 15. 20 is a mounting screw and 21 is a gas conduit port.

Reference numeral 22 denotes a bottom support plate fixed to the wall surface by a mounting screw 20, and the mounting plate 15 is supported by the bottom support plate 22. Reference numeral 23 in the drawing is a gas conduit.

[0018]

[Effects of the Invention] The support fitting according to the present invention is constructed as described above, and the following effects can be expected.

The forward tilt of the connection unit can be finely adjusted by turning the forward tilt adjusting screw, and the support plate can be horizontally adjusted by turning the horizontal adjusting screw. By this action, the gas meter can be properly and easily attached to a predetermined position. Further, since the meter cock and the test port are integrated with the connection unit, the labor for connecting them can be saved.
