Abstract

PURPOSE:To miniaturize and simplify a device by providing one check valve or a plurality thereof in the communicating opening of a rotary part communicated to a plurality of passages in a fluid mixing and distributing device for properly mixing and distributing the fluids of a plurality of distribution systems. CONSTITUTION:The fluids entered through passages 11, 12 are passed through check valves 5, 6 disposed in communicating openings 3, 4 in forward direction and mixed, and the resulting mixture is passed through port parts 9, 10 and run to distribution parts through passages 13, 14. When a rotary part 2 is rotated by 90 deg., the fluids entered through the passages 11, 12 are run to the distributing parts through only the passage 14 without the run to the passage 13, as the check valve 15 is turned in reversed direction. When the rotary part 2 is further rotated by 90 deg., the fluids entered through the passages 11, 12 are never run to the distributing parts by the check function of the check valves 5, 6. When the rotary part 2 is further rotated by 90 deg., the fluids entered through the passages 11, 12 are run to the distributing parts through only the passage 13.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a fluid mixing and distributing device, and particularly to a fluid mixing and distributing device for appropriately mixing and distributing fluids by switching a plurality of flow path systems by rotational operation. Regarding.

<Prior art> Usually, when mixing multiple pressurized fluids and distributing them appropriately, the sixth
As shown in the figure, a large number of switching valve devices are provided, and fluids are mixed and distributed by selectively switching these valve devices.

That is, in FIG. 6, a plurality of channels 50, 51, 52
．． 53, 54 are communicated via switching valve devices 55, 56, 57, 58, and by appropriately switching the switching valve devices 55, 56, 57, 58, desired mixing and distribution of fluids is achieved. The fluids in channels 50 and 51 are mixed and the fluids in channel 52 are mixed.
If the fluid is to be distributed from the flow path 53, the switching valve device 55, 56, 57 is opened and the switching valve device 58 is closed. When distributing, use a switching valve device 55°57.58
This can be done by opening the valve and closing the switching valve device 56.

<Problems to be Solved by the Invention> However, in the conventional fluid mixing and distributing device shown above, switching valve devices are required for the number of channels, and as the number of parts increases, the device becomes larger and more complex. There was a problem in that the control system became too crowded, or that the control for controlling a large number of switching valve devices became complicated.

Therefore, the technical problem of the present invention is to obtain a compact and simple fluid mixing and dispensing device, which allows mixing and dispensing of desired fluids with simple control.

Means for solving the above problems> The technical means of the present invention taken to solve the above problems are as follows:
A plurality of intersecting communication openings are provided in the rotary part and the rotary part, and one or more check valves are arranged at arbitrary locations in the communication openings of the rotary part. , a boat portion is formed opposite to the communication opening of the rotary portion and communicating with the plurality of flow paths.

Function> Fluids from multiple channels are mixed by passing through the boat section and the intersecting communication openings of the rotary section, and
In the communication opening provided with the check valve, the fluid can flow down in the forward direction, but cannot flow down in the reverse direction. Therefore, by appropriately rotating the rotary part and arranging a communication opening without a check valve in the flow path to be distributed or a communication opening with a check valve located in the forward direction, the desired mixture and distribution of fluid can be achieved. (I can also say te.

<Example> An example showing a specific example of the above technical means will be described. (See FIGS. 1 to 5) First embodiment (See FIGS. 1 and 2) In FIG. Communication openings 3 and 4 that intersect and pass through each other, and a check valve 5 disposed within the communication openings 3 and 4.
, 6, boat portions 7.8, 9.10 formed opposite to the ends of the communication openings 3, 4, and these boat portions 7, 8,
9.10, and four channels 11, 12.'13.14 for communicating with a mixed fluid source (not shown) outside the system and a distribution point (not shown), respectively.

As shown in FIG. 2, the check valves 5 and 6 have a collar 20 at one end for attachment to the respective flow path, and a notch-shaped valve part 21 at the other end. It has a tapered valve passage 22 from the center of the valve part 20 to the valve part 21. In the valve passage 22, the collar portion 20 side is the inlet side, and the valve portion 21
The side forms the exit side. The check valves 5 and 6 are made of an elastic material such as synthetic rubber, and the valve portion 21 is closed in the free state (the state shown in FIG. 2). Valve passage 22 of check valves 5 and 6
When fluid flows into the chamber from the inlet side, that is, from the collar portion 20 side, the valve portion 21 opens due to the pressure of the fluid, allowing the fluid to flow down. On the contrary, when fluid flows in from the outlet side of the check valves 5 and 6, that is, from the valve portion 21 side, the fluid pressure acts on the tapered valve portion 21 to close the valve passage 22.

In FIG. 1, (b) shows a state in which the rotary part 2 in FIG. (a) has been rotated 90';
Figures C) and (d>) show the state in which Figures (b) and (C) have been rotated by 90'.

In FIG. 1(a), the fluid flowing in from the channels 11 and 12 passes through the check valves 5 and 6 arranged in the communication openings 3 and 4 in the forward direction and is mixed with the boat parts 9 and 10. through channels 13 and 14 to the distribution point. When the rotary part 2 is rotated 90' from FIG. 1(a) (the state shown in FIG. 1(b)), the fluid flowing in from the flow path 11. Instead, it is allowed to flow down to the distribution point only through the channel 14. When rotary part 2 is further rotated 90' (state shown in figure (C))
The fluid flowing in from the channels 11 and 12 does not flow down to the distribution location due to the check function of the check valves 5 and 6. When the rotary part 2 is further rotated by 90' (the state shown in FIG. 3(d)), the fluid flowing in from the channels 11 and 12 is forced to flow down only from the channel 13 to the distribution location.

Next, in FIG. 1(a), when fluid flows in from channels 11 and 13, the fluid does not flow down to channel 12 due to the non-return function of check valve 6, and instead flows into channel 4. Only the fluid flows down.

As described above, only by rotating the rotary section 2, fluids from desired flow paths can be mixed and distributed to the desired flow paths.

In this embodiment, an example is shown in which two check valves, one each in the communication opening 3.4, are arranged, but the number of check valves may be one depending on the mode of distribution. There may be one or three pieces.

Second Embodiment (See FIG. 3) In this embodiment, the same members as in the first embodiment are denoted by the same reference numerals, and a detailed explanation of the fluid mixing and distributing device will be omitted.

In FIG. 3(a), the fluid that has flowed in from the channels 11 and 13 is caused to flow down from the channel 14. When the rotary section 2 is rotated by 90 degrees (the state shown in the figure (b)), the fluid from the channels 11 and 13 is not allowed to flow down to the other channels. When the rotary section 2 is further rotated by 90' ((C ), the fluid from the channels 11 and 13 is allowed to flow down only into the channel 12.

Third and Fourth Embodiments (See FIGS. 4 and 5) In this embodiment as well, the same members as in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, the number of communication openings in the rotary portion 2 is greater than that in the first and second embodiments.

In FIG. 4, communication openings 30.31 and flow channels 32.
33, 34, 35, and check valves 36, 37 are further provided.

FIG. 5 shows an example in which the arrangement position of the check valve in FIG. 4 is changed.

<Effects of the Invention> According to the present invention, desired fluids can be mixed and distributed with a simple operation of rotating one rotary part, and valve devices can be arranged according to the number of channels. There is no need to do this, and the device can be made small and simple.
