Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fixing a gas meter around a gas meter to a pipe shaft (pipe collection space) or a wall or a column raised on the ground when a flexible pipe is used for gas piping. The present invention relates to a gas meter mounting unit for use in a vehicle.

[0002]

2. Description of the Related Art Generally, a gas meter is installed so as to be suspended from an inlet pipe member and an outlet pipe member made of metal pipes which are normally raised from the ground. However, since a flexible pipe (hereinafter, referred to as a "flexible pipe") has come to be used for a pipe around a gas meter in recent years, the gas meter cannot be supported by inlet and outlet pipe materials. Therefore, there is a demand for a proposal of a dedicated support bracket for installing the gas meter itself in a pipe shaft, on a wall, or on the ground. As a conventionally proposed support fitting, an inlet and an outlet elbow and a bend pipe are fixed to a single support bar, a base of a gas meter is connected to this, and both ends of the support bar are fixed to a wall, It is fixed to a pillar.

[0003]

However, the above-mentioned known fixing method has the following disadvantages. a. In the case of a gas meter, the positions of the connection bases provided on the inlet side and the outlet side are fixed, so if the inlet and outlet elbows and bend pipes are attached to the support bar, the positioning must be performed accurately. Connection is impossible. For this reason, when attaching the elbow and the bend tube to the support bar, it is necessary to carefully perform the positioning, and the work is troublesome.

B. Since the elbow and the bend pipe are attached to the support bar and the gas meter is attached to the support bar by the on-site work, the work is difficult to perform, especially in a narrow pipe shaft. c. Piping costs are high due to the large number of parts. d. The attached gas meter is easily obstructed because the position of the installed gas meter is largely located on the front side, and in the case of the inside of the pipe shaft, it may obstruct other pipes. An object of the present invention is to provide a gas meter mounting unit which has solved the above-mentioned disadvantages a to d.

[0005]

The construction of the gas meter mounting unit according to the present invention is as follows. 1. On the left and right sides of the front side, a long hole for attaching the inlet side piping member and the outlet side piping member are respectively formed, a column is fixed rearward by lowering the space between the long holes by one step, and both left and right ends are further lowered by one step. A mounting plate formed with a plate fixing portion, an inlet piping member formed with a fixing portion with a parallel surface fitted to the inlet slot facing rearward, and A gas meter mounting unit, comprising: an outlet pipe member having a fixing portion with a parallel surface to be fitted facing rearward; and a fixing bolt for fixing the inlet pipe member and the outlet pipe member to a mounting plate. 2. The gas meter mounting unit according to the above item 1, wherein the gas flow path is formed in the shape of a triangle, and a gasket is incorporated in the gas flow path, and a main cock provided with a handle for opening and closing the gasket is used as an inlet piping member. .

[0006]

[Function] The mounting plate may be fixed directly to the wall,
Alternatively, it may be fixed using a C-type channel or the like. Alternatively, in the case of mounting on the ground, a support may be erected and fixed to this point. Before fixing in this manner, the inlet-side piping member and the outlet-side piping member may be temporarily fixed to the mounting plate using fixing bolts, and may be brought to the site. Alternatively, a gas meter may be attached in advance. Since the inlet-side piping member and the outlet-side piping member are fixed in a plane parallel to the elongated hole, the directions do not go out of order. However, adjustment for adjusting the distance between the bases (centering) of the gas meter is performed by loosening the fixing bolt.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounting plate formed by pressing a metal plate is advantageous in terms of cost. A long slot is formed on the mounting plate on the left and right, and the fixed parts of the inlet and outlet pipe members, which are formed with upper and lower parallel surfaces just fitting in the elongated hole, are fitted from the front side, and the fixing bolt Is screwed in from the back side and fixed.

[0008] The mounting plate may be provided with a fixing portion which can be directly fixed to the wall, or a fixing means which can be fixed to the C-shaped channel, for example.
Further, the mounting plate may be provided with a column fixing portion at the center so that the mounting plate can be fixed to a column standing up from the ground.

[0014]

As described above, according to the present invention, the mounting plate, the inlet side piping member and the outlet side piping member are unitized, and the mounting plate can be freely mounted on the pipe shaft, the meter box, the column, etc. is there. Therefore, the following effects are obtained. a. Due to the unitization, parts can be temporarily stopped, and work on site can be easily performed. b. The parts are unitized, and if the parts including the gas meter are fixed in advance, the fixing work in the narrow pipe shaft hardly occurs, and the work is not troublesome.

C. By using a gas stopper as the inlet-side piping member, the number of piping parts is reduced, and the piping cost is reduced accordingly. d. By fixing the mounting plate directly to the wall, the amount by which the gas meter projects to the front side is reduced. e. When used in combination with the C-shaped channel in the pipe shaft, the position of the mounting plate (gas meter) can be slid left and right. Therefore, connection with other piping is simplified. f. Since the inlet and outlet pipe members are fixed to the mounting plate by aligning the oblong hole and the parallel surface, the directions are not disturbed.
