Problems solved by technology

However, the tightening force of the bolts will inevitably decrease over time. Therefore, regular tightening must be performed to prevent leakage at the joint caused by a decrease in the tightening force, that is, a decrease in torque.
In the case of sealing with a gasket, a very high fastening force is required; therefore, the fluid supply and discharge parts of the integrated panel and the fluid device must have high strength, and at the same time, it is not conducive to the work for making the connection

Embodiment 1

[0119] FIG. 1 and FIG. 2 show the connection structure of the integrated panel and the fluid device according to the first embodiment. The connection structure between the integrated panel and the fluid device is a single-channel type structure, which consists of an integrated panel 1 with a pair of circular tubular fluid flow channels 3 and 4 formed inside and an upper surface 1a of the integrated panel 1 separated by a The valve (opening and closing valve, shut-off valve, etc.) 2 mounted on the annular gasket G is constituted, and shares the longitudinal axis P. That is, a pair of connection structures for the supply and row use the same structure as each other.

[0120] As shown in FIGS. 1 and 2 , the integrated panel 1 has a structure in which a pair of cylindrical supply-side fluid flow passages 3 and 4 are formed inside a panel material (or block material) 5 made of a fluororesin such as PFA or PTFE. The supply-side fluid flow channels 3 and 4 are constituted by vertica...

Embodiment 2

[0143] FIG. 4 shows the connection structure of the integrated panel and the fluid device of the second embodiment. This is a structure in which the integrated panel 1 is connected to the filter 2, which is an example of a fluid device, and the connection structure itself is the same as that of Embodiment 1 shown in FIGS. 1 to 3 . Therefore, the same reference numerals are attached to the same positions, and the description thereof will be omitted.

[0144] The filter 2 is composed of a main body case 2K, a lower case 2B, and a filter body 2C, and the lower case 2B is formed with a fluid flow passage 7 on the supply side and a fluid flow passage 8 on the discharge side, and the state of having these fluid flow passages 7 and 8 is formed. A pair of mounting flanges 9 and 9 are formed by protruding lower laterally. These mounting flanges 9 , 9 and the integrated panel 1 are connected via a gasket G in communication.

Embodiment 3

[0146] As shown in FIG. 5 , the connection structure between the integrated panel and the fluid device in Embodiment 3 is an example of the integrated panel 1 and the fluid device, that is, the connection structure of the regulator 2 . The regulator 2 includes a casing 2C composed of an upper case, a middle case, and a lower case. Between the upper case and the middle case, a bellows tube (not shown) whose peripheral parts are clamped is accommodated. A valve body (not shown) whose peripheral portion is clamped is accommodated between the case and the lower case, and a return spring is accommodated in the lower case.

[0147] The housing 2C is integrally provided with a pair of mounting flanges 9 and 9 protruding in the lateral direction, and the regulator 2 is connected to the integrated panel 1 via the gasket G by these mounting flanges 9 and 9. Surface 1a. The connection structure between the mounting flange 9 and the upper surface 1a of the integrated panel 1 through the ...

Abstract

A connection structure between an integrated panel and a fluid device, in which excellent sealing properties can be maintained almost without requiring retightening and in which workability in assembling them is improved. This is achieved by communicatingly connecting both the integrated panel and a valve (2), with circular tube-like fluid paths (3, 7) sealed by an annular gasket (G). To make the connection, an annular projection (11) and tapered circumferential surfaces (12a, 13a), located inside and outside the projection (11), are formed at each of a first and a second fluid supply / discharge opening (2A), and the gasket (G) made of fluorocarbon resin has a pair of annular grooves (51, 51) and tapered circumferential surfaces (52a, 53a). When the integrated panel (1) and the valve (2) are pulled together, the annular projection (11) and the annular grooves (51) are fitted together to form sealing sections (S1) where the tapered circumferential surfaces (12a, 13a, 52a, 53a) are in intimate contact with each other.

Description

Technical field [0001] The present invention relates to a connection structure between an integrated panel and a fluid device. Specifically, it relates to a high-performance device used in manufacturing processes in various technical fields such as semiconductor manufacturing, medical and pharmaceutical product manufacturing, food processing, chemical industry, etc. via a sealing gasket. Integrated panels for fluids that are expected to be needed in the future, such as piping systems for pure liquids, ultrapure water, or cleaning fluids, and a connection structure that connects fluid devices such as pumps, valves, and reservoirs in a sealed state. Background technique [0002] Known connection structures include, for example, the connection structures disclosed in Patent Document 1 and Patent Document 2, which connect a pair of supply and discharge pipes to each other and connect a valve of one of the fluid components to an integrated panel with a fluid flow channel formed in...
