Definitions
- the invention relates to a concealed pipe interrupter according to the preamble of claim 1.
- Pipe interrupters are used in drinking water pipes in the flow direction between the water shut-off and the water drain, such as. B. installed a shower hose to prevent the back suction of contaminated water into the drinking water network in the event of a pressure drop in the drinking water line.
- the pipe interrupter is formed with air inlet openings, which are open in a conventional design at zero flow and are only closed from the inside by moving parts of the pipe interrupter at internal pressure-generating water flow and which on the outside of the pipe interrupter z. B. must be formed by the mouth between deeply cut housing ribs so that covering and closing of the air inlet openings on the outside of the pipe interrupter is prevented.
- a flush-mounted installation of pipe interrupters is often desired, especially in the sanitary area, instead of an exposed installation.
- a tubular interrupter functional part is inserted, when inserted into a round flush-mounted box, with the end faces of its inlet and outlet ends butt against the end faces of the two line connections opening into the flush-mounted box at diametrically opposite locations and by O-rings between the end faces of the Interrupter function part and the line connections sealed.
- This requires a precise adjustment of the end faces and the overall length of the interrupter function part to the geometry of the round flush-mounted box and its line connections and makes the flush-mounted pipe interrupter expensive and complicated.
- the object of the invention is therefore to create a flush-mounted pipe interrupter which does not require any expensive and complicated production outlay and which can be installed simply and reliably and can also be serviced during operation.
- the flush-mounted pipe interrupter consists of a wall mounting box 1 and a tubular interrupter function part 2 of a type which is known per se and which requires a downward flow direction.
- the wall mounting box 1 which is open at the front and can be closed by a lid, has on its top an inlet connection 3 and on its underside an outlet connection 4.
- the interrupter function part 2 is formed with a cylindrical outlet end 5 which contains an O-sealing ring 6 on its circumference and which can be inserted axially into the outlet connection 4 and sealingly with the O-ring 6.
- the functional part 2 is formed with an axial length that is shorter than the clear distance between the openings of the two connections 3 and 4 in the wall installation box 1.
- a sliding sleeve 7 is inserted, which is axially displaceable in the inlet connection 3 and sealed with an O-ring 8.
- a removable clip 12 is placed on the sliding nozzle 7, which clip fills the distance between an end face 13 of the inlet connection 3 and a stop shoulder 14 formed on the sliding nozzle 7, so that the sliding grommet 7 cannot inadvertently retreat into the inlet connection 3.
- the wall box 1 is provided inside with ribs 15, which are provided with a trough-shaped recess 16 adapted to the circumferential contour of the interrupter functional part 2, that the functional part 2 is guided through the ribs 15 in a position in which the Longitudinal axis of the functional part 2 essentially with the longitudinal axes of the two connections 3 and 4 are aligned. This simplifies the insertion of the functional part 2 into the drain connection 4 and the insertion of the sliding spout 7 into the functional part 2 in a quick and safe manner.

Claims (3)
- Interrupteur tubulaire encastré, constitué d'un boîtier à encastrer dans un mur (1), ayant un raccordement d'amenée supérieur (3) et un raccordement de départ inférieur (4) et pouvant être obturé en face avant par un couvercle amovible, et constitué d'une partie fonctionnelle à rôle d'interrupteur (2) sensiblement tubulaire, insérée dans le boîtier de façon étanche et permettant son extraction, entre les deux raccordements débouchant dans le boîtier, caractérisé en ce que la partie fonctionnelle (2) présente une longueur axiale inférieure à la distance libre entre les embouchures des deux raccordements (3, 4) dans le boîtier (1), en ce que, en outre, la partie fonctionnelle est réalisée avec une extrémité de sortie (5) cylindrique, pouvant être enfichée à l'aide d'un joint d'étanchéité à anneau torique (6) dans le raccordement de départ (4) du boîtier, et en ce que le raccordement d'amenée (3) du boîtier est réalisé avec une manchette coulissante (7), déplaçable axialement, isolée de façon étanche dans le raccordement et dont l'extrémité (9), sortant du raccordement d'amenée, peut être enfichée, avec un joint d'étanchéité à anneau torique (11), dans l'extrémité d'entrée (10) de la partie fonctionnelle.
- Interrupteur tubulaire encastré selon la revendication 1, caractérisé en ce que sur la manchette coulissante (7) peut etre enfichée, après enfichage dans la partie fonctionnelle (2), un collier (12), remplissant la distance entre une face frontale (13) du raccordement d'amenée (3) et un épaulement de butée (14), sur la manchette coulissante.
- Interrupteur tubulaire encastré selon la revendication 1 ou 2, caractérisé en ce que le boîtier de montage dans un mur (1) est pourvu a l'intérieur de nervures (15), qui sont réalisées avec une cavité (16) en forme d'auge, adaptée au contour périphérique de la partie fonctionnelle à fonction d'interrupteur (2), cavité à travers laquelle la partie fonctionnelle (2) est guidée lors de l'insertion dans le boîtier (1), le guidage se faisant coaxialement par rapport aux deux raccordements (3, 4) du boîtier.
