The invention relates to a device for installing piping of process plants of the food and beverage industry according to the preamble of claim 1. The object of the invention is to create a device for installing piping of the generic type, which at high operating reliability satisfies the highest requirements on the quality of the fluid product handled therein, which overall, including the mix-proof valves, is simple and cost-effective to build, and which in all arrangement variants of the valve distribution tree occurring in practice forms to the greatest extent possible the same technological conditions and state variable as in the process assembly or tank with respect to the assigned process assembly or tank of the process system in-the respective valve distributor tree. In addition, a direct impact of the seat region of the mix- proof valve during seat cleaning should be avoided, and the leakage cavity should be formed to be self draining. This is attained in that the respective valve distributor tree (B1, B2, ..., Bi, ..., Bn) opens directly into the lower tank bottom (T1a, T2a, ..., Tia, ..., Tna) of the respectively assigned tank (T; T1, T2, ..., Ti, ..., Tn) of the process plant, and/or that the respective valve distributor tree (B1, B2, ..., Bi, ..., Bn) is connected via an assigned pipe connection (R; R1, R2, ..., Ri, ..., Rn) to an assigned process assembly (P; P1, P2, ..., Pi, ..., Pn) or tank (T; T1, T2, ..., Ti, ..., Tn) of the process plant and the pipe connection (R; R1, R2, ..., Ri, ..., Rn) opens into the tank or process assembly end of the valve distributor tree (B1, B2, ..., Bi, ..., Bn), that the second closing member (11) is designed as a hollow rod and the second seat seal (13) is received in a face surface of the second closing section (11), designed as a hollow rod, facing towards the first closing member (10), that the second closing member (11), designed as a hollow rod, has on the inside at its end section receiving the second seat seal (13) a cylindrical receiving bore (11b) which is designed with the same diameter as the cylindrical first seat (6b), and that in the closed position of the second closing member (11) the receiving bore (11b) and the first seat (6b) are merged together in a flush manner (Figure 6).
Système de tuyauterie pour des installations de traitement des industries alimentaires et des boissons, dans lequel, selon l'invention, l'arbre distributeur à soupapes débouche directement dans le fond d'une cuve associée de l'installation de traitement et/ou l'arbre distributeur à soupapes est raccordé par l'intermédiaire d'un tuyau de raccordement associé à une unité de traitement ou à une cuve de l'installation de traitement, et le tuyau de raccordement débouche dans l'extrémité de l'arbre distributeur à soupapes située du côté de la cuve ou de l'unité de traitement, le second obturateur se présente sous forme de tige creuse et le second joint d'étanchéité de siège est logé dans une face frontale, orientée vers le premier obturateur, du second obturateur en forme de tige creuse, le second obturateur en forme de tige creuse possède au niveau de sa partie terminale recevant le second joint d'étanchéité de siège, du côté interne, un trou de réception cylindrique qui possède le même diamètre que la première surface de siège cylindrique, et dans la position de fermeture du second obturateur, le trou de réception et la première surface de siège s'emboîtent l'un dans l'autre pour se trouver au même niveau.
