Description

  In the present invention, a manifold for mounting a plurality of solenoid valves is configured by die casting of a pair of identical parts, and a manifold for mounting an arbitrary number of solenoid valves is configured by die casting of two types of parts. The present invention relates to a solenoid valve manifold that can be made.

For example, as disclosed in Patent Document 1, it is conventionally known that an arbitrary number of manifolds having a single valve mounting surface for mounting a solenoid valve are connected to form a multiple solenoid valve manifold. It has been.
In this multiple solenoid valve manifold, an end connecting member for connecting an external pipe is provided at one or both ends in the manifold connecting direction, and pressure fluid is supplied to the collective pressure fluid supply / discharge passage of each manifold. Although it is configured to exhaust, it is necessary to connect at least three types of parts including the connecting members at both ends even if all the manifolds on which the solenoid valves are mounted are common. Must be manufactured and stored. Therefore, it is desirable to reduce the number of parts as much as possible.

  In addition, on the valve mounting surface on the upper surface of each manifold, there are a plurality of supply / discharge holes arranged corresponding to each connection port of the solenoid valve, but since the solenoid valve has been remarkably miniaturized in recent years, The plurality of connection ports provided on it have a very short interval between the ports, while the interval between the joints of the external piping provided on the end connecting member is to connect the pipes with a standardized diameter. Therefore, the interval between the connection ports of the solenoid valve is remarkably larger than that of the connection port. Therefore, the end connecting member connected to the joint of the external pipe and the flow path for supplying and discharging the collective pressure fluid in the manifold also have a large diameter. The road spacing will be large.

Therefore, in the manifold in which the solenoid valve is mounted, if the collective pressure fluid supply / discharge passage and the plurality of supply / discharge passages corresponding to the respective ports of the solenoid valve are made to communicate with each other, the passage Becomes complicated, or the holes are formed obliquely from the electromagnetic valve mounting surface, which complicates the manufacturing process. Also, for example, as disclosed in Patent Document 2, a plurality of supply and discharge ports corresponding to each port of the solenoid valve can be provided by shifting the positions of the adjacent collective pressure fluid supply and discharge flow paths up and down. When the passage extending from the through hole to the collective pressure fluid supply / discharge passage is formed by a vertical hole from the electromagnetic valve mounting surface, the manufacturing process such as perforation for forming the through hole is simplified. There is a problem that the manifold itself increases in size up and down.

Due to improved flow path formation, individual supply to communicate with solenoid valves that have a wide installation interval, such as a collective supply flow path and a collective discharge flow path on both sides of the flow path, and a very narrow installation interval. The through holes and the individual discharge through holes on both sides thereof can be communicated with each other by the communication passage formed perpendicular to the valve mounting surface, thereby facilitating die-casting of parts constituting the manifold.

  As illustrated in FIGS. 1 and 2, the manifold for solenoid valves according to the present invention includes at least a pair of die-cast end manifolds 10 having the same shape, and each of them includes two stations on which two solenoid valves can be mounted. Therefore, it can be configured as a four-unit manifold capable of mounting four solenoid valves by the connection. Further, in order to increase the number of manifolds on which solenoid valves are mounted, an intermediate manifold 30 sandwiched between the pair of end manifolds 10 is used as clearly shown in FIGS. .

  As can be seen from FIGS. 1 to 7, the pair of end manifolds 10 are connected to their bodies 10 a by a first connecting surface 11 that can be connected to each other and a pipe connection that faces away from the first connecting surface 11. It has the surface 12 and the 1st valve mounting surface 13 with the flat upper surface for mounting | wearing with mounting | wearing with the solenoid valve which is not shown in figure. As shown in FIGS. 5 and 6, the pipe connection surface 12 is formed by opening a collective supply flow path 15 having a circular cross section and a pair of collective discharge flow paths 16 having a circular cross section on both sides thereof. A pipe joint for connecting an external pipe to each flow path is formed to be connectable. Further, as shown in FIGS. 5 and 7, the first connecting surface 11 includes a first supply communication passage 18 having a vertically long cross section extending to the inside of the first valve mounting surface 13, and the same in both sides thereof. A pair of horizontally long first discharge communication passages 19 extending to the inside of the first valve mounting surface 13 are opened.

The supply through hole 21 communicates with the first supply communication path 18, and the individual discharge through hole 22 communicates with the first discharge communication path 19 on both sides of the first supply communication path 18.

To the first connecting surface 11 and the individual supply through hole 21 and the individual discharge through hole 22 opened to the first valve mounting surface 13. In order to communicate with each other, it is necessary to open the through holes 22 obliquely from the first valve mounting surface 13 toward the collective discharge flow path 16, which makes it difficult to die-cast the end manifold.

The through holes 41 and 42 are also opened perpendicular to the second valve mounting surface 33.

Further, the pair of second connecting surfaces 31 are provided with convex portions 44 and concave portions 45 having the same shape at the same positions as the positioning convex portions 24 and the concave portions 25 on the first connecting surface 11 of the end manifold 10, and A screw hole 43 is provided at a position corresponding to the screw hole 23 for attaching the solenoid valve of the end manifold 10, and the protrusion 46 having the same shape is formed at the same position as the protrusion 26 of the end manifold 10 and the recessed portion 27 receiving the same.

In connecting the second connecting surface 31 in FIG. 3, it is desirable to use a connecting clip 59 as shown in FIGS.
For fixing by the connection clip 59, both side surfaces 14 of the body 10a adjacent to the first connecting surface 11 of the end manifold 10 and both side surfaces 34 of the body 30a adjacent to the second connecting surface 31 of the intermediate manifold 30 are provided.
