(DE) VERFAHREN UND VORRICHTUNG ZUM EINSATZ VON VENTILEN IN EINEM KANAL
(EN) VALVE INSERTION METHOD AND ASSEMBLY FOR INSERTING A VALVE IN A LINE
(FR) PROCEDE ET EQUIPEMENT PERMETTANT D'INTRODUIRE UN ROBINET DANS UNE CONDUITE
Abrégé
(EN) A method for inserting a valve in a line includes the step of providing a valve assembly (10) having a valve body (11) with two sections (17, 18) adapted to be assembled over an existing pipe (14) and gate (12) adapted to cut through the pipe (14) as the gate (12) advances from an open position toward a closed position. The method proceeds by installing the valve assembly (10) on the existing pipe (10) with the gate (12) in the open position and then moving the gate (12) toward the closed position to thereby cut through the pipe (14). A rotatable pipe-cutter version of a valve assembly (10) constructed according to the invention includes at least one cutting tooth (21) and the valve body (11) is configured so that an operator (13) can rotate the body (11) on the existing pipe (14) while the gate (12) is advanced toward the closed position. A guillotine version, suited for use with pipes made of polyethylene and other sliceable materials, includes a gate (12) with a cutting edge that slices through the pipe (14) as the gate (12) is advanced toward the closed position.
(FR) Un procédé d'introduction d'un robinet dans un conduite consiste à utiliser un ensemble de robinetterie (10) ayant un corps (11) comportant deux parties (17, 18) conçues pour être assemblées au-dessus d'une conduite existante (14) et un opercule (12) conçu pour sectionner la conduite (14) lorsqu'il se déplace d'une position d'ouverture à une position de fermeture. Ledit procédé consiste tout d'abord à installer l'ensemble de robinetterie (10) sur la conduite existante (10), l'opercule (12) étant en position d'ouverture, puis à amener l'opercule (12) en position de fermeture de façon à sectionner la conduite (14). Une version de l'ensemble de robinetterie (10) dotée d'un organe rotatif de sectionnement de conduite fabriqué conformément à l'invention comporte au moins une dent coupante (21) et le corps (11) du robinet est conçu pour qu'un opérateur (13) puisse faire tourner le corps (11) sur la conduite existante (14) tandis que l'opercule (12) est amené en position de fermeture. Une version à guillotine, utilisable avec des conduites composées de polyéthylène et d'autres matières susceptibles d'être sectionnées, comporte un opercule (12) à bord coupant qui sectionne la conduite (14) lorsque l'opercule (12) est amené en position de fermeture.
