Description

  The present invention relates to a two-dimensional integrated piping technology for a fluid control device.

  A fluid control device is generally composed of a circuit in which various valves and instruments that are operated in response to various signals such as electricity or fluid pressure are combined and connected to each other via a pipe line. Conventionally, as shown in FIG. 6, various valves 11 a, 11 b, 11 c or measuring instruments are attached to the mounting plate 10 with bolts, and each port is connected with pipes 12 a, 12 b, 12 c, etc. It was.

  However, since the production efficiency shown in FIG. 6 is poor particularly for mass production, for example, an integrated piping system as shown in FIG. 7 has been proposed (see Patent Document 1). This outline will be described with reference to FIG. The integrated piping shown in FIG. 7 is basically composed of a plate 1 and a lid 4. A flow path corresponding to the conventional pipe 12 is formed in the plate 1 as groove-like fluid passages 1a, 1b, 1c... And necessary holes 1a ', 1b', 1c '. The lid 4 is mainly formed with mounting seats for control devices such as valves and holes 4a, 4b, 4c. Then, the plate 1 and the lid 4 are bonded with a resinous adhesive while keeping the air-water tightness, so that the flow path formed by the conventional pipe 12 is formed without the pipe.

The technique disclosed in FIG. 7 is excellent in that the production process can be shortened, the apparatus can be miniaturized, and quality problems such as leakage are reduced, but there are problems in the following points.
1) In the technique disclosed in FIG. 7, since the plate 1 and the lid 4 are bonded with a resinous adhesive, it is difficult to disassemble. Moreover, even if it can be disassembled, reassembly is troublesome.
2) In equipment for handling food and chemicals, there are many cases in which piping must be thoroughly cleaned from every corner because of the need for hygiene or the need to eliminate residues. It is difficult to clean the grooved fluid passage 1 completely with the flow of the cleaning agent, and it is necessary to disassemble and clean the inside directly.

  This invention is made | formed in view of the said subject, and it aims at providing the two-dimensional integrated piping which can be decomposed | disassembled and has high air-water tightness.

The two-dimensional integrated piping according to the present invention that solves the above problems is
A plate having a groove-like fluid passage and a through-hole penetrating the fluid passage;
A lid that is in pressure contact with the plate and forms a fluid passage that seals the fluid passage;
Sealing means interposed between the plate and the lid;
A U-shaped member disposed outside the plate and the lid, and rotatably provided at an end of the U-shaped member, the plate and the lid can be press-contacted when disposed at a predetermined position. and a lever, and a detachable fastening means wearing when the lever is disposed in another predetermined position,
An opening is provided in the center of the plate and the lid or at an arbitrary position, and the fastening means is used for the opening and the side end of the plate and the lid, so that the plate and the lid are evenly pressed. and features that you have to be.
In the above two-dimensional integrated piping,
The sealing means is a sheet-like sealing member opened along the shape of the fluid passage, or a packing inserted into a groove formed around the fluid passage.

  According to the present invention, a detachable sealing means (gasket, packing, etc.) is sandwiched between the plate and the lid without bonding the plate and the lid with a resinous adhesive, and an easily removable fastening such as a clamp. Since the pressure contact is made using the means, it is possible to ensure air-tightness and facilitate assembly and disassembly. As a result, the groove-like fluid passage can be directly cleaned whenever necessary.

  The two-dimensional integrated pipe according to the present invention sandwiches sealing means such as packing and gasket between a plate and a lid, and presses the plate and lid using a fastening means such as a clamp and a screw, thereby providing a gas-watertight seal. The structure is easy to assemble and disassemble while ensuring the performance. Embodiments of the two-dimensional integrated piping according to the present invention having such characteristics are shown in FIGS. 1 to 5 and will be described in detail.

  The two-dimensional integrated pipe according to the present invention has a plate 20 and a lid 21, which are basically the same as the conventional plate 1 and lid 4 shown in FIG. Specifically, the plate 20 is provided with grooved fluid passages 20a, 20b,... And through holes 20a ′, 20b ′,. In addition, the lid 21 is pressed against the plate 20 so that the grooved fluid passages 20a, 20b,... Control devices such as valves are attached to the plate 20, and the groove-like fluid passages 20a, 20b,... Communicate with control devices such as valves through the through holes 20a ′, 20b ′,. The fluid is controlled. In the present invention, in order to make it possible to disassemble the plate 20 and the lid 21 as easily as possible, it is desirable to mainly arrange control devices such as valves on the plate 20 side. However, if there is no influence on the work of disassembling the plate 20 and the lid 21, a control device such as valves may be arranged on the lid 21 side.

  If the plate 20 and the lid 21 are simply press-contacted, leakage between the fluid passages is caused by a minute gap on the press-contact surface. Therefore, in the present invention, as shown in FIG. 1, a gasket 22 (sealing means) is interposed between the plate 20 and the lid 21, and the plate 20 and the lid 21 are clamped by a clamp 40 (fastening means) described later. By pressure welding, the air tightness of the fluid passage is maintained. Further, since the clamp 40 is easily detachable, the plate 20 and the lid 21 can be easily disassembled and reassembled. The gasket 22 is formed in a shape in which the fluid passage portion is cut out using a sheet-like sealing material (in FIG. 1, the shape is shown by mesh-like hatching), and the fluid passages 20a, b,. .. by surrounding each independently so as to prevent leakage between the outside and other fluid passages.

  As the sealing means, packings 23a, 23b, 23c,... May be used as shown in FIG. Specifically, the packings 23a, 23b, 23c,... Are packing grooves 20a ", 20", 20c formed around the groove-like fluid passages 20a, 20b, 20c,. .. (See FIG. 2B), and the lid 21 is pressed from above to prevent leakage between the outside and other fluid passages.

  The sealing means using the gasket 22 or the packing 23 described above is not particularly limited to this, and may be appropriately selected depending on the application such as the characteristics of the fluid and the operating pressure. For example, as the packing 23, various things such as an O-ring shape, a V-shaped packing, a U-shaped packing as shown in FIG.

FIG. 3A is a diagram showing an example of the fastening means of the present embodiment, which is a clamp-type pressure contact method. FIG. 3B shows a sectional view of the clamp portion.
As shown in FIGS. 3A and 3B, the clamp 40 is a U-shaped U-shaped member 43 disposed outside the plate 20 and the lid 21 so as to sandwich the plate 20 and the lid 21. have. Further, a lever 41 is rotatably supported by a pin 42 at an end of the U-shaped member 43, and a convex portion for making the outer peripheral radius different at a portion of the lever 41 around the pin 42. 41a is provided. The U-shaped member 43 is formed so that the inner width thereof is slightly larger than the thickness of the plate 20 and the lid 21, so that when the lever 41 is tilted toward the surface of the lid 21, the portion of the convex portion 41 a is the lid 21. To press the plate 20 and the lid 21 together. And when the lever 41 is stood perpendicularly to the surface of the lid | cover 21, the press of the lid | cover 21 by the convex part 41a is cancelled | released, and it becomes possible to remove the clamp 40 easily. In the clamp 40 shown in FIGS. 3A and 3B, the lever 41 is provided only at one end of the U-shaped member 43, but not only at one end but at both ends. You may make it provide the lever 41 in a part.

  By attaching a plurality of such clamps 40 to the side ends of the plate 20 and the lid 21, the plate 20 and the lid 21 can be pressed against each other while maintaining airtightness. Further, by removing the clamp 40 at the time of maintenance, the plate 20 and the lid 21 can be easily disassembled, and when reassembling, it can be easily assembled as in the disassembly. Further, when the gasket 22 shown in FIG. 1 or the packing 23 shown in FIG. 2 is expected to change over time, the plate 20 and the lid 21 can be easily disassembled. It can be easily replaced.

  The clamp 40 can be completely removed from the plate 20 and the lid 21. However, when the loss of the clamp 40 is considered, one end of the clamp 40 is the plate 20 (or as shown in FIG. 3C). A clamp 44 supported on the lid 21) may be used. Specifically, the clamp 44 includes an L-shaped L-shaped member 45, and one end portion of the L-shaped member 45 is freely rotatable by a pin 47 on the protruding portion 46 of the plate 20 (or the lid 21). The other end of the L-shaped member 45 can be disposed on the upper surface of the lid 21 (or the plate 20). By disposing the other end of the L-shaped member 45 on the upper surface of the lid 21 (or plate 20) and tilting the lever 41 provided rotatably at the other end on the surface of the lid 21, The plate 20 and the lid 21 can be pressed against each other, and by pressing the lever 41 vertically to the surface of the lid 21, the pressure on the lid 21 is released and the clamp 44 can be removed.

  In the above-described clamp-type pressure contact method, basically, only the side end portions of the plate 20 and the lid 21 can be pressure-contacted. It is desirable that the lid 21 itself has a predetermined rigidity. When the plate 20 and the lid 21 do not have a predetermined rigidity, the center portion of the plate 20 and the lid 21 is supplementarily fastened with an appropriate number of screws or the like, so that the plate 20 and the lid 21 can be connected to each other. You may make it not impair airtightness.

  Also, as shown in FIGS. 4 and 8, if openings 48 and 49 are provided at the center of the plate 20 and the lid 21 or at an arbitrary position and the sheet-like gasket 22 is used as a sealing means, the gasket 22 is used. An opening similar to that of the plate 20 and the lid 21 is provided at the center of the plate and at an arbitrary position, and a plurality of clamps 40 are attached to the side of the opening 48 and the plate 20 and the lid 21, so that the plate 20 and The center portion of the lid 21 is also securely pressed evenly so that the air-tightness between the plate 20 and the lid 21 is not impaired. This is particularly useful when using a material with low rigidity, such as a resin material, as the material of the plate 20 and the lid 21. For example, if the plate 20 and the lid 21 are configured using a transparent resin material, It is possible to visually confirm the flow of the fluid and the presence or absence of dirt or residue of the fluid passage from the outside, and it is possible to achieve an appropriate maintenance timing.
