Definitions

  • the invention relates to a distributor device for connecting at least two valves, in particular valves for sterile applications, in each of which a translationally displaceable closing member switches a seat with a circular passage cross section, and to an interior space in a housing of the distributor device, which is connected to the respective passage cross section via connection openings is.
  • valves used in these piping systems must have certain properties that enable them for these sterile applications.
  • the valve rod actuating the closing member for example, is a critical area in the area of its passage through the valve housing to the respective drive, since at this point the valve rod movement (so-called elevator effect) may cause germs can be dragged into the product from the environment and thus a sterile application is questioned.
  • a product film adhering to the valve rod may be transported into the sealing area or beyond by the switching movement and contaminated there with germs from the environment. This contaminated product film is then possibly brought into the product space by the switching movement of the rod and, under certain circumstances, leads to impairment of the product present there by so-called recontamination.
  • diaphragm valves or suitable lift valves are used, with the latter in each case being bridged by means of a bellows or corrugated tube connecting the valve housing to the closing element.
  • a diaphragm valve in the case of a diaphragm valve, as is known, for example, from DE 199 83977 T1 or US Pat. No. 5,273,075, a diaphragm closes flow paths within a valve body, which are formed there between an inlet and an outlet.
  • the membrane is clamped in the valve body and is moved in the vertical direction by a movement mechanism.
  • the flow paths of the valve body communicate with each other through a non-protruding connection path, the membrane snugly fitting against the connection path when lowered to occlude the flow path and to open the flow path when it is raised.
  • the advantage of such a diaphragm valve is, in particular, that the switching element moving the diaphragm is arranged outside the product space and the product space is separated from the external environment by the diaphragm statically clamped in the valve body.
  • a disadvantage of such diaphragm valves is that they have significantly larger cross-sectional areas than connection cross-sections.
  • such diaphragm valves can be recognized purely externally from the fact that they are equipped with a relatively large drive compared to the valve body. Due to the disproportion between the cross-sectional area of the seat and the cross-sections of the connection, dead spaces and / or areas which are not sufficiently flowed through arise in the respective transition areas, which at least make proper flow cleaning difficult.
  • valve blocks are provided (US Pat. No. 6,112,767), to which a large number, for example, of the membrane valves described above can be connected.
  • the valve blocks have an essentially cubic spatial shape, whereby for example, four to six diaphragm valves can be connected to each block half.
  • a single valve block contains the valve bodies of the connected diaphragm valves with their respective flow paths, their valve seats, the connection geometry and the necessary cross connections.
  • a disadvantage of such a distribution system is its lack of flexibility, since the number of diaphragm valves that can be connected to the valve block is determined by the respective block geometry.
  • distributor trees so-called linear distributors
  • other distributor geometries welded together from molded pipe parts in particular ring distributors
  • These distributor systems also have at least some of the disadvantages of the sterile valve blocks described above and, moreover, further disadvantages which result from the production and the properties of the weld seams which are regularly present in a large number.

Each of these connection openings is assigned a valve which is designed to be safe from mixing in its seating area and which switches the connection between the interior and the respectively connected pipeline in the immediate vicinity of the hollow body.
  • the known distributor device itself is largely free of dead space and it also has sufficient idling properties, since it is oriented essentially vertically.
  • the predominantly horizontally arranged valves can be problematic in terms of their idling, since, depending on the design, small residual quantities can often remain in the seating area.
  • the known distributor device is a so-called linear distributor which, in order to ensure the desired properties in connection with the tank outlet len, must be arranged essentially vertically.

L'invention concerne un dispositif répartiteur servant à raccorder au moins deux soupapes, notamment des soupapes destinées à des applications stériles. Dans chacune de ces soupapes, un organe d'obturation, pouvant effectuer un mouvement de translation, coopère avec une surface de siège présentant une section de passage circulaire. Un compartiment intérieur, communiquant avec chaque section de passage par l'intermédiaire d'orifices de raccordement, est formé dans un boîtier dudit dispositif répartiteur. L'objectif de l'invention est de créer un dispositif répartiteur (1; 1 *) de conception simple, compact, sans espace mort, facile à nettoyer et pouvant être totalement vidé. A cet effet, le compartiment intérieur (2; 2*) se présente sous la forme d'un canal annulaire fermé (2; 2*), défini par rotation d'une surface plate génératrice (A2; A2*) autour d'un axe de rotation (D) qui ne coupe pas ladite surface (A2; A2*); le canal annulaire (2; 2*) est formé entre deux parties (1.1, 1.2; 1.1*, 1.2*) constituant le boîtier (10; 10*); le canal annulaire (2; 2*) est étanchéifié vis-à-vis de l'environnement par l'intermédiaire de deux bagues d'étanchéité (4, 5 ou 7, 8) placés entre les parties de boîtier (1. 1, 1.2; 1. 1 *, 1.2*); et les orifices de raccordement (3.1, 3.2, ..., 3.n; 3.1*, 3.2*, ..., 3.n*) sont situés en des points déterminés de la périphérie du canal annulaire (2,; 2*) et de la surface génératrice (A2; A2*).
