摘要:
The invention relates to a quick-acting connecting arrangement (1) for a pressure vessel (20). The arrangement (1) comprises a closure lid (10) having an enclosing portion (11) on which a radially encircling groove is arranged on the inner side. The arrangement (1) further comprises a pressure vessel (20) having an engagement portion (21) which has an encircling projection (22). The closure cover (10) is pushed with its enclosing portion (11) over the engagement portion (21) of the pressure vessel (20), with the groove (12) and the projection (22) facing one another. The arrangement (1) further comprises an elastic ring element (30) having two mutually opposite bearing faces (31a, 31b). The ring element (30) is applied with the first bearing face (31a) to a stop face (24) on the projection (22) and with a second bearing face (31b) to a stop face (14) of the groove (12). The two bearing faces (31a, 31b) are inclined and converge towards one another in the direction (R) of the encircling groove (12). Furthermore, the invention also relates to an actuating device for actuating a quick-acting connecting arrangement.

The invention provides a closure suitable for use on pipelines and pressure vessels, and which can resist high pressure but which can be opened quickly when the pressure differential across the closure has been reduced to zero. The closure comprises a door (3) which fits into an aperture of a hub (1) in a member (2) to be closed. A number of arcuate locking members or segment blocks (30) disposed around the periphery of the door for locking the door (3) to the hub (1). The locking members (30) are constrained by guide pins (34) to move along guide slots (40) in the door. A drive plate (101) is rotatably mounted on the door (3) and includes a plurality of drive slots (122) which engage with the guide pins (34). Rotation of the drive plate (101) relative to the door (3) causes the locking members (30) to move radially outwardly and circumferentially such that the locking members are moved from an unexpanded unlocked position to an expanded locking position in which the locking members (30) engage both the door (3) and the hub (1) thereby preventing opening of the door. A key member (82) is moved to a position between two adjacent locking members(30) to lock the closure. The closure is unlocked by removing the key member (82) and then rotating the drive plate (101) to move the locking members (30) back to the unexpanded unlocked position.

A closure assembly 10 contains positive and/or vacuum pressure within a pressure vessel 16 having a neck 12 . A circumferential locking member 22 supported on a door 20 locks the door to the neck, and is radially moveable between an open position and a closed position. A seal 26 between the neck and the door maintains fluid-tight integrity. A lever or other hand powered operator may be used for moving the locking member between the open position and the closed position. The locking member may include locking segments interconnected to form the circumferential locking member.

The invention relates to a locking device for fixing a lid (1) to the opening (8) of a pressure vessel, comprising at least two locking segments (5) that can be moved crosswise relative to the axis of the opening (8), said locking segments having projecting elements (6) and groove-shaped recesses in their periphery that in closed position cooperate with recesses (7) or projecting elements in the edge of the opening, wherein the displacement drive mechanism (4) of the segments (5) is hinged to the segments (5) and at least one site of action arranged on the lid (1) or on a component (3) that is connected to the lid (1). According to the invention, the segments (5) arranged in peripheral direction of the lid (1) are supported in an articulated manner on the lid (1) by means of a pivoting arm (16) that is separate from the displacement drive mechanism (4).

The invention relates to a quick release coupling device comprising an annular groove (4) formed on the inner face of one of the hollow bodies, a projecting part (6) formed on the other hollow body (2) and a force transmitting member (5) engaged with the groove and the projecting part (6). A shoulder (23) is provided for fixing the force transmitting member (5) to hinder the loosening of the coupling under loading. The inventive device is advantageous in that its design and use are straightforward while meeting the requirements related to safety and ease of cleaning.

57 Ce dispositif de mise en place et de maintien d'une plaque d'obturation (11) d'un orifice (7) comporte un anneau porteur (21) muni d'une gorge interne (22) a une face inclinée (23) à l'intérieur de laquelle sont positionnées des cales de bridage (25) qui s'appliquent sur la périphérie de la plaque d'obturation (11) et qui, sous l'action de vis de blocage (27) ou de vérins (70) coopérant avec l'anneau porteur (21) se déplacent individuellement dans ladite gorge selon une direction radiale et dés- cendante pour exercer un effort de compression sur ladite plaque d'obturation.
摘要:
Enceinte étanche pour fluides à haute pression du type comportant un corps central tubulaire fermé à au moins une de ses extrémités par un bouchon inséré à l'intérieur dudit corps central tubulaire et étant bloqué contre tout effort, tendant à le faire sortir par un joint torique, reposant d'une part contre un épaulement circulaire oblique (5) ménagé dans ledit bouchon (2, 3, 20) et d'autre part dans une gorge, au moins patiellement cylindrique (6) ménagée dans la paroi interne du corps cylindrique. La pente de l'épaulement oblique (6) et la position de la gorge cylindrique (D) sont la résultante (R) des efforts de compression appliqués sur le jonc soit portée par une droite traversant toute l'épaisseur (E) du corps (1, 21) de l'enceinte.
