Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a manifold valve structure.
[0002]
[Prior art]
  For example, in a factory or the like, a fluid such as pure water may flow through a pipe and be supplied to a predetermined work place. At that time, depending on the intended work or product, chemicals required for the fluid such as pure water are mixed at a predetermined flow rate and supplied as a main fluid, or a plurality of one fluid such as the main fluid is supplied. In some cases, a manifold valve structure 50 as shown in FIGS. 13 and 14 is connected in the middle of the piping.
[0003]
  The manifold valve structure 50 includes a substantially rectangular parallelepiped main body block 51 and a sub-block 55 including a valve mechanism 60.
  In the main body block 51, a plurality of main body side communication openings 52 are formed downward from the upper surface of the main body block 51 into the main body block 51 at predetermined intervals in the longitudinal direction. A main fluid passage 53 in the horizontal direction along the longitudinal direction of the body block 51 is formed at the lower end position of the body side communication opening 52, and the main fluid passage 53 and the body side communication opening 52 communicate with each other. . At least one end (one in the illustrated example) of the main fluid flow path 53 is provided with a main fluid outflow inlet 54 serving as a connection port with a pipe or the like, and the main fluid outflow inlet 54 is a valve structure 50. Open to the outside.
[0004]
  On the other hand, a plurality of (three in the illustrated example) auxiliary blocks 55 are arranged in parallel on the upper surface of the main body block 51. In the lower part of each sub-block 55, a sub-block side communication opening 56 that communicates with the upper end of the main body side communication opening 52 is formed in the vertical direction, and the upper end of the sub-block side communication opening 56 and the valve mechanism 60 are formed. A sub-fluid outflow port 57 for a sub-fluid (pure water, chemicals, etc.) communicating through the lower part of the sub-block 55 is formed in the horizontal direction from the front or the back of the sub-block 55. The valve mechanism 60 includes a valve portion 61 that is raised by air and lowered by a spring 65. The valve portion 61 is provided to open and close the sub-block side communication opening 56. Reference numeral 62 denotes a diaphragm.
[0005]
  In the manifold valve structure 50 having the above-described structure, a supply device for chemicals or the like is connected to the sub-fluid outflow / inlet 57. Then, if necessary, the valve mechanism 60 of the sub-block 55 is actuated appropriately to open the sub-block side communication opening 56, so that a predetermined amount of sub-fluid flows through the sub-block side communication opening 56 and the main body block side communication opening 52. It can be supplied into the main fluid channel 53. In addition, when supplying a plurality of sub-fluids by switching, the upper ends of other corresponding sub-block side communication channels may be opened by the operation of the valve mechanism 60 corresponding thereto.
[0006]
  However, in the conventional manifold valve structure 50, the number of sub-fluids to be supplied can be accommodated according to the user's needs, in other words, the sub-block 55 (sub-fluid outflow inlet 57) to be combined. The main body block 51 had to be designed each time to match the number, and the versatility was poor. In addition, when it is necessary to increase or decrease the number of sub-fluids to be supplied after installing the manifold valve structure in a factory or the like, it is necessary to newly change and replace the main body block 51. It was disadvantageous.
[0007]
  In addition, in the conventional structure, the main fluid outflow inlet 54 and the subfluid outflow inlet 57, which serve as connection ports with piping or the like, are generally formed in directions orthogonal to each other as shown in the figure. As a result, when the manifold valve structure 50 is installed so that the flow direction of the main fluid and the flow direction of the sub-fluid outside the manifold valve structure 50 are parallel, the installation space for the manifold valve structure 50 is reduced. In some cases, there was a restriction such as the need to make it wide. Specifically, as shown in FIG. 12B, the main fluid outlet / inlet 57 of the manifold valve structure 50 is parallel to the flow direction of the sub-fluid outside the valve structure, that is, orthogonal to the main fluid flow path 53. When connecting to the pipe P, the fluid flow needs to be converted by the joint R as shown in the figure, and a wasteful space is created for the joint R.
[0008]
[Problems to be solved by the invention]
  The present invention has been proposed in view of the above points, and is excellent in versatility, and can easily and quickly cope with changing the number of secondary fluids to be supplied after installation, etc. It is an object to provide an advantageous manifold valve structure.
