[Prior Art] A valve manifold that combines multiple valve mounting bases for centralized control is, for example,
It is already known from Japanese Patent No. 53-10573, and the valve mounting base of the above-mentioned known valve manifold is capable of mounting the valve by screwing the valve mounting bolt into a screw hole provided directly on the valve installation surface. It is intended to establish a

However, in order to provide a screw hole on the valve installation surface, the valve mount needs to be made of a strong material such as metal.
There is a problem in that it is not possible to use materials such as synthetic resins, which are lightweight and inexpensive, but have low strength.

[Problem to be solved by the invention] The problem to be solved by the invention is to provide a valve mounting base that can be made of a lightweight, inexpensive, and low-strength material.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a plurality of fluid passages that open to the valve installation surface, and a plurality of fluid passages that penetrate between opposing connecting surfaces and connect to each of the fluid passages separately. In a valve manifold that connects a plurality of valve mounting bases each having a plurality of through passages, the valve mounting base has a plurality of metal fitting insertion holes on each connecting surface, and a plurality of metal fitting insertion holes on the valve installation surface. A plurality of mounting holes are provided that open into the insertion hole, and a mounting fitting that also serves as a positioner and is inserted into the fitting insertion hole has a size that can be inserted into both insertion holes of an adjacent valve mounting base, and the fitting fitting is inserted into the fitting insertion hole. Provide a screw hole for mounting the valve at a position opposite to the above mounting hole when inserted into the hole,
Insert the fitting insertion hole of the next valve mounting block into the protruding part of the above-mentioned fitting inserted into the fitting insertion hole of the previous valve mounting block to connect multiple valve mounting blocks, and connect each valve mounting stand. The valve is attached to the valve installation surface using a mounting bolt that passes through the mounting hole of the valve and screws into the threaded hole of the mounting fitting.

[Operation] By inserting the mounting fittings into the fitting insertion holes on the continuous surface of the preceding valve mounting base, and inserting the fitting insertion holes of the next valve mounting base into the protruding parts of the mounting fittings, Multiple valve mounting bases can be installed in series without causing any deviation in the direction perpendicular to the direction in which they are connected, and this allows the valve mounting screw holes of the mounting bracket to face the mounting holes on the valve installation surface. .

Therefore, a valve to be installed on a valve installation surface is attached to the valve mounting base by screwing its mounting bolt through the mounting hole of the valve mounting base and into the threaded hole of the mounting bracket, and the valve mounting base has a mounting bolt for mounting the valve. Since there is no need to provide a screw hole, the valve mounting base can be made of a material that is lightweight and inexpensive, but has low strength.

Similar metal fitting insertion holes are provided on the connecting surfaces of the side plates 2 and 2 at positions facing the metal fitting insertion holes 12 and 13 of the valve mounting base 1.
A supply port 15 and discharge ports 16, 16, which communicate with the through passages 7, . . . respectively, are opened in the continuous direction. However, when the valve mounting bases 1, . . . and the side plates 2, 2 are connected by connecting bolts passing through them as described later, the metal fitting insertion holes in the side plates 2, 2 can be omitted.

The mounting bracket 3 has a size that can be inserted into the metal fitting insertion holes 12, 13 of the valve mounting base 1, and approximately half of its length protrudes from the metal fitting insertion holes 12, 13,
A threaded hole 1 for mounting the valve is located at a position facing the mounting hole 11 when inserted into the fitting insertion holes 12, 12.
8 is provided, and this screw hole 18 connects the mounting bracket 3 to any of the insertion holes 1 of the adjacent mounting bases 1, 1.
2 and 13, it is provided at a position facing the mounting hole 11.

Although not shown, the mounting bracket 3 may be provided with two screw holes 18 for mounting the valve, and when the mounting bracket 3 is formed in this way, the screw holes 18
The mounting fitting 3 can be inserted into the fitting insertion holes 12 and 13 without considering the position of the fitting 8.

Next, the arrangement of the valve mounting bases 1 in the above embodiment will be explained.

Insert the open side of the valve mounting screw hole 18 of the mounting bracket 3 into the metal insertion hole of the side plate 2, and insert the opposite side of the screw hole 18 of the mounting bracket 3 into the other metal insertion hole to connect the valve mounting base 1. A metal fitting insertion hole 13 provided on the surface 6,
12 into the protruding parts of these mounting fittings 3, the side plate 2 and the valve mounting base 1 can be connected to each other without causing any deviation in the direction perpendicular to the direction in which they are connected. Next, similarly insert the mounting fittings 3, 3 into the fitting insertion holes 12, 13 of the other connecting surface 6 of this mounting base 1, and insert the fitting insertion holes 13, 12 of the next valve mounting base 1 into the fitting insertion holes 12, 13 of the next valve mounting base 1. They are inserted into the protruding parts of the mounting fittings 3, 3, and this operation is repeated to install the desired number of valve mounting bases 1, . . . and side plates 2, 2 in series. Continuously installed valve mounting bases 1, ... and side plates 2, 2
A valve manifold can be obtained by connecting them by an appropriate connecting means such as passing a connecting bolt (not shown) through them.

The valve mounting bases 1 and 1 and the valve mounting base 1 and the side plate 2 are connected by connecting bolts each time they are connected, as disclosed in, for example, Japanese Utility Model Application No. 62-89582. You can also.

To install a valve (not shown) on the valve mounting bases 1, which are connected in this way, place the valve on the valve installation surface 9 of each valve mounting base 1, and tighten the mounting bolts 20 to the valve mounting parts. Then, it may be inserted through the mounting hole 11 of the valve mounting base 1 and screwed into the valve mounting screw hole 18 of the mounting bracket 3. Therefore, since the mounting bolt 20 is not directly screwed onto the valve mount 1, the valve mount 1 can be made of a material that is lightweight and inexpensive but has low strength.

In addition, the metal fitting insertion hole 1 in which the mounting hole 11 is opened
2 is T-shaped in side view as shown in the figure, the threaded end of the mounting bolt 20 is inserted into the threaded hole 18 for mounting the valve.
Since it can be protruded from the mounting bolt 2

Note that the reference numeral 17 in FIG. 2 is a mounting hole in the side plates 2, 2.

[Effect of the invention] The present invention eliminates the need to provide a screw hole in the valve mount by screwing the valve mounting bolt into the valve mounting screw hole of the mounting bracket inserted into the valve mount through the mounting hole. Furthermore, since the valve can be installed on the valve mount, the valve mount can be made of a material that is low in strength but lightweight and inexpensive.

Further, since the above-mentioned mounting bracket allows positioning when the valve mounts are installed in series, the valve mounts can be installed in series without causing any deviation in the direction perpendicular to the direction in which the valve mounts are installed.
