摘要:
The body (1) of the tapping insert incorporates, in correspondence with one of the extremities of the classical groove (4) for temporally coupling of the knife or guillotine (6) which closes the insert during the dismounting operation of the drilling bit and until the definitive implantation of the derived pipe, a small bolt (7) acting as a rocking axis for said knife or guillotine (6) which is provided at its extremities with a small bent protuberance (9), as a hook, for its hinged junction to the bolt (7), and at its opposite extremity a handle (10) for its manipulation during the rocking operation with a lever movement which provides for a more comfortable and fast closing operation requires less efforts. A seal is incorporated to the body (1) of the tapping insert which is intended to be mounted coaxially and externally to the same, thereby closing said groove (4) after removing the knife (6), said seal being embodied as a plastic ring having a certain deformation capacity.

A self-sealing bag valve for use with a quick-disconnect coupling in a bag-in-box (BIB) syrup dispensing assembly for a post-mix beverage dispenser includes a plastic spring assembly (10) for normally biasing a poppet (30) of a self-sealing valve into sealing engagement with a valve seat (38) thereof. The spring assembly (10) includes a petaloid-shaped disc (14, 16) having evenly spaced petaloid segments (14a, 16a) defining flow passages therebetween, a retaining ring (12) for securing peripheral portions of the petaloid-shaped disc in fixed positions in the bore of the self-sealing valve and a petaloid stem (18) protruding from the disc into engagement with the valve poppet. The petaloid-shaped disc includes a first frusto-conical portion extending from the retaining ring to a circular termination line concentric with the ring and a second frusto-conical portion extending from the circular termination line to the petaloid stem. The first and second frusto-conical portions, when in an installed, normal biasing position (the closed position of the self-sealing valve), have opposite slopes with respect to an axis orthogonal to the petaloid disc providing a bend about the circular termination lines forming knees in each petaloid segment for accommodating flexing of the elements about the knees. A groove (50d) is provided in the central bore of the valve housing for accommodating a snap-fit (12a) of the retaining ring (12) therein.

A two-part coupling structure (20, 22) includes a male coupling part (22) and a female coupling part (20) which are mutually engageable to open fluid communication between a fluid-storage vessel (18) and a conduit (16). The coupling parts are disengageable from one another to discontinue fluid communication between the vessel and the conduit, and also to close communication between ambient and each of the vessel and conduit. The retention volume of fluid which is trapped between the connected male and female coupling parts and which is exposed to or lost to ambient when the coupling parts are disconnected is very small. Because of particular structural features, the coupling parts will function reliably even with fluid having chunks or particulates of non-fluid material therein.

Ce dispositif comprend un corps de vanne (6) monté de manière étanche à travers la paroi (2) d'une enceinte (3) et un obturateur (7) reçu dans ledit corps, et des moyens (4) pour raccorder sélectivement de manière étanche ladite enceinte (3) à une canalisation (5) dans une position ouverte dudit obturateur. Les moyens de raccordement (4) comprennent un manchon amovible (18) adapté pour être fixé extérieurement de manière étanche audit corps (6) et un organe (23, 31) d'actionnement dudit obturateur (7) monté à rotation dans ledit manchon (18) pour déplacer ledit obturateur dans ledit manchon entre une position fermée et ladite position ouverte dans laquelle ladite enceinte (3) communique avec ladite canalisation (5) par l'intermédiaire dudit corps (6) et dudit manchon (18).
摘要:
Assembly comprises a preferably collapsible liquid-product container (1), a pump (3) and tube (4) liquid-transporting system and a quick coupling device (5) for connecting the tube to the container, the coupling device comprising a suction (16) extending into the container, a mating tube-adaptor member - (7) and a non-return valve (17) in its passage. The system provides optimal user convenience and safety, allowing quick and safe connection of replacement liquid-product containers to the tube and pumping system.
摘要:
Des dispositifs de raccordement hydraulique sont utilisés dans des réceptacles (60) tels que des réceptacles montés sur un équipement d'aspiration chirurgicale pour la connexion sélective d'un conduit de fluide (94) dans le réceptacle (60) avec un passage d'écoulement (14) formé au travers du dispositif de raccordement. Le dispositif de raccordement comprend une broche (30) qui est maintenue de manière non rotative dans le réceptacle (60) et un corps (10) monté de manière rotative sur la broche (30) pour effectuer un mouvement entre une position ouverte dans laquelle la communication est établie entre le conduit d'écoulement (94) dans le réceptacle (60) et le passage d'écoulement (19) dans le dispositif de raccordement, et une position fermée. La broche (30) est formée avec une surface de came (39) pour solliciter un organe d'insertion de came (24) vers l'extérieur lorsqu'il est déplacé en registre avec le conduit d'écoulement (94) dans le réceptacle (60) de sorte qu'une lèvre d'étanchéité annulaire (26) se trouvant sur la surface extérieure de l'organe d'insertion de came (24) soit comprimée autour du conduit d'écoulement (94) pour former un joint d'étanchéité efficace.
摘要:
A manifold valve for use with both automatic valves and shutter valves, which valve includes a full-diameter valve housing (2) having a threaded coupling portion (7) and cylindrical coupling portion (8), for fitting into corresponding seats (9, 10) formed in the manifold body (6). A tight seal is provided by 0-rings (12, 14) accommodated in respective seats (11, 13). The threaded coupling portion (7) is formed with a collar (17) adapted to bear on the manifold body (6). Passage windows (15) are formed through the valve housing (2) for the fluid. A connection fitting (19) is formed on the valve housing (2) for connection to the heating system piping (16).
摘要:
A device (100) for the insertion and positioning of a probe (4) for measuring data from a fluid comprises a guide (2) couplable to suitable shut-off means (90) provided on a channel (70). The device (100) comprises a probe-holder (3) engageable inside the guide (2) in such a way as to permit the insertion of the head (41) of a probe (4) in the right position in the through lumen of the fluid in the channel (70). The device (100) further comprises coupling means (215,315) between the probe-holder (3) and the guide (2) suitable to guide and lock the axial sliding of the probe-holder (3) in the guide (2) in open configuration of the shut-off means (90).
