Title (EN) SINGLE USE VALVE
(FR) VALVE A USAGE UNIQUE
Abstract: front page image
(EN)A single use valve (10) comprises a plate (12) having an internal filter structure (28). A sealing substance (20) covers an inlet (14) to the filter structure (28). A heater arrangement (16) is arranged at the plate (12) in the vicinity of the sealing substance (20) for converting electrical current into heat and thereby melting or evaporating the sealing substance (20) . The heater arrangement (16) conducts at least a part of the current, and preferably the entire current, along a conduction path not including the sealing substance (20) . The melting of the sealing substance (20) thereby becomes independent on the existence of a complete electrical connection through the sealing substance (20). The heater arrangement (16) has therefore preferably its main heat emission in an area surrounding the sealing substance (20). The sealing substance (20) can be of any non-porous material.
(FR)Valve (10) à usage unique comportant une plaque (12) dotée d'une structure (28) filtrante interne. Une substance (20) de bouchage recouvre une entrée (14) de la structure (28) filtrante. Un dispositif (16) chauffant est agencé au niveau de la plaque (12) au voisinage de la substance (20) de bouchage pour convertir un courant électrique en chaleur et faire ainsi fondre ou s'évaporer la substance (20) de bouchage. Le dispositif (16) chauffant conduit au moins une partie du courant, et de préférence la totalité du courant, le long d'un chemin de conduction ne comprenant pas la substance (20) de bouchage. La fusion de la substance (20) de bouchage devient ainsi indépendante de l'existence d'une connexion électrique complète à travers la substance (20) de bouchage. Le dispositif (16) chauffant assure donc de préférence sa principale émission de chaleur dans une zone entourant la substance (20) de bouchage, celle-ci pouvant être constituée de tout matériau non poreux.
