    摘要： Bolt bores in lower members each comprise a large-diameter portion larger than the head of a bolt in diameter, and a small diameter portion extending downward from the large-diameter portion with a stepped portion formed therebetween and having a diameter intermediate between the diameter of the bolt head and the diameter of the shank of the bolt. A heat insulator has a spacer inserting hole. A hollow cylindrical spacer having an inside diameter larger than the diameter of the bolt shank is inserted through the small-diameter portion of the bolt bore and the spacer inserting hole so that the upper end of the spacer is positioned in the large-diameter portion. The spacer has a lower end bearing on a support member. A hollow cylindrical elastic member is interposed between the bolt head and the stepped portion for biasing the lower member toward the support member.

    摘要： A regulator for regulating a flow rate is provided with an upper connector having a downwardly opened channel in communication with the regulator. An on-off valve connected to the regulator is provided with a lower connector having an upwardly opened channel in communication with the on-off valve. The upper connector is lapped over the lower connector and removably joined thereto with a screw so as to cause the downwardly opened channel to communicate with the upwardly opened channel. Accordingly, the regulator can be removed singly, for example, when malfunctioning.

    摘要： A diaphragm valve is provided with a removable metallic elastic seating ring (7) having a first passage (10) and at least one second passage (11) extending through it. The first passage communicates with an inlet passage (8) of the valve while the second passage communicates with the outflow passage (9). A first surface (7a) of the seating ring is provided with a valve seat (12) against which the diaphragm (6) may be pressed to block fluid flow through the valve. A second surface (7b) of the seating ring has two annular and axially extending projections (15, 16). The first projection (15) contacts a bottom surface (2a) of valve chamber (2) in a region surrounding the opening where the inflow passage joins the valve chamber. The second projection (16) contacts the bottom surface of the valve chamber around the periphery of the valve chamber. The first projection extends axially of the seating ring to a slightly greater extent than the second projection so that when a diaphragm holder ( 5) presses the diaphragm against the periphery of the seating ring, the seating ring flexes thus causing increased contact pressure between the first projection and the bottom surface of the valve chamber. This reduces the possibility of leakage flow between the bottom wall and the seating ring from the inflow passage to the outflow passage.

    摘要： A fluid controller 2 comprises a controller main body 6 formed with an inlet channel 42 and an outlet channel 43 each having a downwardly open end, an operating portion 7 provided on the main body 6 and integral therewith for opening and closing the outlet channel 43, and a connector 11 provided beneath the main body 6. The connector 11 has an inlet channel 41 for causing an inlet channel 40 of an inlet pipe joint member 1 to communicate with the inlet channel 42 of the main body 6, and a leftwardly open outlet channel 44 communicating with the outlet channel 43 of the main body 6. The controller main body 6 is fastened to the connector 11 with screws 17. The operating portion 7 can be removed from the connector 11 together with the main body 6.
