    摘要: A valve comprises a body including a chamber and two superposed closures moving in the chamber and the bottom part of the chamber includes a first seat for one closure and a second seat for the other closure. The closures are each carried by a swing mobile between a position in which the closure bears in sealed fashion on the corresponding seat and a position in which the closure is spaced from the seat. The space between the two closures contains an elastic material membrane closing a chamber into which a compressed air feed discharges. The membrane can therefore be inflated and pressed in sealed fashion onto the top closure to close and seal the inlet of a passage which discharges into a space between the two closures.

    摘要: The butterfly valve comprises a disk which is provide with at least one protuberance over at least a portion of at least one of its faces. Quite unexpectedly, the use of such a disk makes it possible to improve considerably the quality of the cleaning of the valve and to reduce the time required for cleaning operations.

    摘要: A gate-valve comprising a gate-valve body inside of which a gate-valve seat is formed having a stop surface delimiting the orifice of a pipe, a valve moving in a linear direction in the gate-valve body, the valve having an upper shoulder and a lower shoulder axially distanced from the upper shoulder, and a seal fitted between the two shoulders intended to stop the orifice of the pipe, the pipe having an internal peripheral surface which is parallel with the direction of displacement of the valve, characterized in that the valve comprises a limiting means to limit the flow of a liquid between a surface of the valve and the internal peripheral surface of the pipe during the displacement of the valve while the seal is not completely removed from the orifice of the pipe.
