The diaphragm valve element 30 includes a circular opening / closing seal portion 31 that opens / closes a valve chamber side opening 28o of the branch flow path 28 inside the valve seat 29a,
A thin portion 32 formed outside the opening / closing seal portion 31;
An outer peripheral mounting portion 33 formed outside the thin portion 32 and a screwing portion 34 which is mounted on the opening / closing seal portion 31 and is screwed to a valve driving mechanism 40 (an operating member 41 described later). . The valve body 30 is provided in the valve chamber 29 of the valve body 22 by the outer peripheral mounting portion 33. The opening / closing seal portion 31, the thin portion 32, and the outer peripheral mounting portion 33 are made of rubber or various plastics, and are integrally formed. The screw portion 34 is made of metal or plastic, and a plate-shaped portion 35 provided at the tip is embedded in the opening / closing seal portion 31. Preferably, the surface area (diameter) of the plate-shaped portion 35 is made larger than the opening area (opening diameter) of the valve chamber side opening 28o of the branch flow path 28 so that the valve element 30 is opened.
When the opening / closing seal part 31 closes the valve chamber side opening 28o of the branch flow path 28, the plate-shaped part 35 may preferably cover the entire valve chamber side opening 28o of the branch flow path 28. Then, the valve body 30 can reliably seal the opening of the branch passage 28 on the valve chamber side, and the load on the valve body 30 is reduced, and the durability is improved. Note that reference numeral 2 in FIGS.
Reference numeral 9b denotes a mounting recess formed in the inner wall of the valve chamber 29 for accommodating the outer peripheral mounting portion 33 of the valve body 30.

応することができる。As shown and described above, in the manifold valve structure according to the present invention, each of the manifold valve structure having the through main flow path, the branch flow path, the valve chamber, the valve body, the valve driving mechanism, the sub flow path, and the like is provided. Since the valve block bodies are configured independently of each other, by appropriately combining the valve block bodies,
It is possible to easily provide a manifold valve structure that meets the various needs of the user, that is, the number of fluids (sub-fluids) to be supplied to the inside of the valve structure (or the number of locations where the fluid is distributed and supplied). Excellent. Further, even if the number of fluids to be supplied to the inside after the installation (or the number of places for distributing and supplying the fluid) needs to be changed, the manifold valve structure easily, quickly and at low cost. be able to.

The main flow path connecting member or the main flow path sealing member is connected to the connection convex portion or the connection concave portion, and the connection concave portion or the connection convex portion which is not used for the connection at the end of the valve block body connected to the plurality. It is configured to be connected. Therefore, the connected valve block bodies can have the same structure as each other, that is, only one type of valve block body is required, which is extremely advantageous in cost and design. Further, in the manifold valve structure, the main flow path connecting member and the main flow path sealing member are fixed to the base member via end side fixing members, respectively. It is possible to prevent the sealing member from coming off or coming off the valve block body.
