[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaphragm valve installation section, and is particularly suitable for use in an automatic diaphragm valve installation section having an automatic opening / closing device.

[0002]

2. Description of the Related Art In a conventional diaphragm valve installation section, as shown in FIG. 3, a pipe 2 of a diaphragm valve 1 provided between pipes 2 on an installation surface 51 such as a concrete floor surface. The connection flange portion 17 and the flange of the pipe 2 are provided on the installation surface 51 by the metal band 7 and fixed to the gantry 52. FIG.
In the figure, reference numeral 16 denotes an automatic opening / closing device such as a motor provided in the diaphragm valve 1, and 8 denotes a stand for the pipe 2.

Further, as described in, for example, Japanese Utility Model Application Laid-Open No. 54-39626 and Japanese Utility Model Application Laid-Open No. 57-202060, a metal plate is brought into close contact with a diaphragm holding portion between a bonnet of a diaphragm valve and a flange of a main body. Are known.

Further, as described in, for example, Japanese Utility Model Publication No. 63-16941, a reinforcing material is applied to the upper surface of the flange of the bonnet of the diaphragm valve and the lower surface of the flange of the main body, and a reinforcing plate for holding the main body. Are also connected to a reinforcing material.

[0005]

However, in the conventional diaphragm valve installation portion shown in FIG. 3, the diaphragm valve 3 is fixed to the gantry 5 by the metal band 4, but the motor and the like provided on the diaphragm valve 3 Weight of the automatic opening and closing device 31 of the diaphragm valve 3
In addition, when the weight of the automatic opening / closing device 31 is large in addition to the pipes 2 and 2 connected to the diaphragm valve 3, the load on the pipes 2 and 2 becomes excessive, and the life of the pipes 2 and 2 is shortened. become.

As described in Japanese Utility Model Laid-Open No. 54-39626 and Japanese Utility Model Laid-Open No. 57-202060,
For those in which a metal plate is in close contact with the diaphragm sandwiched by the bonnet of the diaphragm valve and the flange of the main body, the diaphragm valve itself is reinforced, but when a heavy automatic opening / closing device etc. is attached to the diaphragm valve, the diaphragm valve The load on the connected pipe becomes excessive, and the life of the pipe is similarly shortened.

As described in Japanese Utility Model Publication No. 63-16941, a reinforcing material is applied to the upper surface of the flange of the bonnet of the diaphragm valve and the lower surface of the flange of the main body, and the reinforcing plate holding the main body is reinforced. The one connected to the material also has a drawback of shortening the life of the pipe.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional diaphragm valve installation part, and has as its object to solve the above-mentioned problems and to provide a diaphragm valve with a large automatic opening and closing mechanism. It is an object of the present invention to provide a diaphragm valve installation portion in which a load on a pipe connected to a diaphragm valve is not excessively increased even when an apparatus or the like is attached, and the life of the pipe is not shortened.

[0009]

In order to achieve the above object, in the diaphragm valve installation portion of the present invention, a diaphragm valve in which a diaphragm is sandwiched between a flange of a valve body and a flange of a bonnet is installed. In the diaphragm valve installation part installed in the support plate, a support tool having a side wall erected from both sides of the bottom plate part on the installation surface and a support plate part provided on the upper end of both side walls is placed, and the support plate part of the support tool is a valve. It is attached to the lower surface of the flange of the main body.

In the present invention, the material of the support is not particularly limited. For example, a material having relatively high mechanical strength such as steel, aluminum, and FRP can be used.

In the present invention, the installation surface is a surface on which the diaphragm valve is installed, and is not particularly limited. For example, a concrete floor surface, an upper surface of a gantry attached to the concrete floor surface, or the like.

In the present invention, the material of the diaphragm valve is not particularly limited. For example, iron, aluminum, hard vinyl chloride resin, ABS resin, PVD
Materials such as F resin, PPS resin, PEEK resin,
Alternatively, they can be used in appropriate combination.

[0013]

[Function] In the diaphragm valve installation part of the present invention,
Side walls are erected from both sides of the bottom plate portion on the installation surface, and a support tool provided with a support plate portion on the upper end of both side walls is placed, and the support plate portion of the support tool is attached to the lower surface of the flange of the valve body. Therefore, even if a heavy automatic opening / closing device or the like is attached to the diaphragm valve, the flange of the valve body is supported by the support mounted on the installation surface, and an excessive load is imposed on the pipe connected to the diaphragm valve. It does not take.

[0014]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of the diaphragm valve installation portion of the present invention, and FIG. 2 is a perspective view showing a support used in the diaphragm valve installation portion of the present invention shown in FIG.

In FIG. 1, reference numeral 1 denotes a diaphragm valve. In the diaphragm valve 1, a flange 12 of a valve body 11 and a flange 14 of a bonnet 13 are provided.
And the diaphragm 15 is sandwiched between them. Reference numeral 16 denotes an automatic opening / closing device such as a motor provided above the hood 13.

At both ends of the valve body 11, pipe connection flanges 17, 17 are provided.
7 is connected to flanges 21 and 21 provided at the ends of the hard vinyl chloride resin tubes 2 and 2.

Reference numeral 3 denotes a support made by bending a steel plate. As shown in FIG. 2, the support 3 has side walls 32, 32 standing upright from both sides of a bottom plate portion 31.
Support plates 33, 33 are provided at the upper ends of 2, 32, respectively. The bottom plate portion 31 of the support 3 is placed on the top surface of the gantry 5 serving as an installation surface, and is attached to the gantry 5 by a bolt nut 4 inserted through a bolt hole 311 provided in the bottom plate portion 31.

The support plates 33 of the support 3 are in contact with the lower surface of the flange 12 of the valve body 11, and the bolts 6 are inserted through bolt holes 331 provided in the support plates 33. It is attached to the flange 12 of the valve body 11, the flange 14 of the bonnet 13, and the diaphragm 15.

[0019]

[Effects of the Invention] In the diaphragm valve installation part of the present invention, even if a heavy automatic opening / closing device or the like is attached to the diaphragm valve, the flange of the valve body is supported by the support mounted on the installation surface, and the diaphragm valve is installed. Since the pipe connected to is not overly burdened,
There is no danger of shortening the life of the piping.
