The ferrule comprises: a rising part (13c) including a first end part (13a); a pressed part (13d), located further toward the second end part (13b) than the rising part; and an intermediate part (13e) including a portion having a larger inner diameter than the first end part and the second end part, and connecting the rising part and the pressed part. The first member comprises a first tapered inner peripheral surface (11a), which is a tapered inner peripheral surface in contact with the first end part of the ferrule. The second member comprises a pressing part (12a), which presses at least a part of the pressed part of the ferrule. The housing space comprises a first allowance space (15a), which is capable of housing the ferrule and lifting the rising part so as to increase the angle with respect to the outer peripheral surface of the pipe.

A joint that connects pipelines, a pipeline with a fluid control device, or a pair of fluid control devices is provided therein with a pipe functional component. Examples of the pipe functional component include various valves such as a diaphragm valve, a check valve, a branch valve, a relief valve, a ball valve and a bellows valve, or a filter.

Fitting structure including a pair of connection pipes and a clamp ring
An engagement section of a holder is engaged with a metal gasket, the gasket is received in a tubular section, and the tubular section is fitted in a step of a connection pipe. Another connection pipe is placed close to and facing the connection pipe that holds the gasket through the holder, and a center ring is installed surrounding the outer peripheries of the flanges. While a trapezoidal section having slopes which define both sides is inserted into a groove, center ring segments are closed to form a ring shape. A bolt which penetrates through a cutout of a segment is screwed into a threaded hole of the segment. The screwing of the bolt causes the amount of insertion of the trapezoidal section, which has slopes which define both sides, into the groove to be increased. As a result, the distance between flanges is reduced and the contact pressure of projections against both sides of the gasket is increased.
A method and a device for bending a metal hollow thick-walled member to a specified angle without deviation of the bending center position and without separation from a semi-die when an extrusion die moves up. With a pair of guide plates turnably attached to a center pin CP kept horizontal and the axis center of the center pin intersecting with the axis center of the metal hollow thick-walled member PM, the member PM is mounted on a semi-die (82a). When metal die holding members fixed to the above guide plates and kept horizontal are inclined and separated from each other as the center pin lowers, the member PM is bent to a specified angle and held on a semi-die (82b). When the center pin that can be moved vertically by a guide member moves down to a specified bending position, a contact portion (96b) contacts the inclined surface of a stopper (92b) to allow a base plate (16) to receive a pressurizing force from an upper die via the stopper.

B30B 1/10 - Presses, utilisant un élément pilonnant, caractérisées par le mode d'entraînement du pilon, la pression étant transmise au pilon ou à la platine de presse directement ou uniquement par l'intermédiaire d'organes travaillant en simple poussée ou traction par un mécanisme à bascule
An engagement section (7a) of a holder (7) is engaged with a metal gasket (6), the gasket (6) is received in a tubular section (7b), and the tubular section (7b) is fitted in a step section (5a) of a connection pipe (1a). Then, another connection pipe (1b) is placed close to and facing the connection pipe (1a) that holds the gasket (6) through the holder (7), and a center ring (9) is installed surrounding the outer peripheries of flanges (2a, 2b). Subsequently, while a trapezoidal section having slopes (3a, 3b) as opposite sides is inserted into a groove (14), segments (10a-10c) are closed to form a ring shape. A bolt (11) penetrated through a cutout (12) of the segment (10a) is screwed into a threaded hole (13) of the segment (10c). The screwing of the bolt causes the amount of insertion of the trapezoidal section, which has the slopes (3a, 3b) as opposite sides, into the groove (14) to be increased. As a result the distance between the flanges (2a, 2b) is reduced and contact pressure of projections (4a, 4b) against both sides of the gasket (6) is increased.
