Title: Connecting structure of fluid equipment for chemicals
Inventor: FURUTA MASAKI
IPC: F16K27/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a connecting structure of fluid equipment for chemicals, which achieved compactness at the time when the fluid equipment for chemicals is connected to each other. SOLUTION: In order to connect a valve 11 and a regulator 12, the first joint surface of the valve 11 and the second joint surface of the regulator 12 are closely adhered to be fixed, and to connect the opening part of the first passage of the valve 11 and the opening part of the second passage of the regulator 12. At this time, the projected part of the second joint surface of the regulator 12 is brought into pressure-contact with the first recessed part of the first joint surface of the valve 11 to be fitted in it. Then, since the first recessed part of the first joint surface and the projected part of the second joint surface are both made of a resin, restoring force of the resin is generated on the pressure-contact part. Further, the first recessed part of the first joint surface surrounds the opening part of the first passage.  Thus, leakage of the connecting part between the opening part of the first passage of the valve 11 and the opening part of the second passage of the regulator 12 can be prevented.

Abstract: PURPOSE:To reduce a load to the drive of a driving cam board during mode switching operation by providing an auxiliary lever and supporting the load due to the pre-load of a slider. CONSTITUTION:When the loading of a tape is completed, a second engaging pin 33, which is planted to an auxiliary lever 30, is positioned near an end part in the tip side of a cam groove 29 to be formed in a cam lever 5. Thus, when a rotary moment is operated in a direction, which is shown by an arrow G, to the cam lever 5 by energizing force to give the pre-load to sliders 20 and 21, the direction of the tangent force of this rotary moment is coincident with the direction of a straight line which connects a supporting shaft 31 of the auxiliary lever 30, the second engaging pin 33 and a first engaging pin 32. Accordingly, this force is supported by the auxiliary lever 30 through the second engaging pin 33 and the load is not loaded to a cam part 2 of a driving cam board 1. Thus, when the driving cam board 1 is rotated in order to switch an operation mode, the load can be reduced.
