摘要： A flexible double toric sealing ring comprising two toric sealing ring structures 2, 3 which ensure, respectively, a static seal and a dynamic seal. A counter ring is mounted radially on the second sealing ring structure and floats with it to allow self centering of the arrangement with respect to the valve seat. A sealing membrane 8 presents an elastically deformable structure 12 interconnecting the two sealing ring structures 2 and 3 while partially covering them. The two sealing ring structures 2, 3 are mounted on opposite sides of the middle section 11 of membrane 8. This double toric sealing ring can be advantageously applied to a butterfly valve.

摘要： An actuator for a valve in which valve opening and closing is effected via a rectilinearly movable member having, at one end, a driving device and, at its other end, a return-movement arrangement. To-and fro movement of the member under the control of the driving device and return-movement arrangement opens or closes the valve, or vice versa.The return-movement arrangement includes a ramp connected to the member and a resilient energy storing cushion for acting oppositely to the driving device on the member with a bridging roller transmission rolling contacting the ramp so that, depending on direction of movement of the member, energy is either stored in or dissipated from the cushion.

摘要： A butterfly valve comprising a body having an internal cylindrical bore with two radial co-axial passages diametrically opposed with respect to the bore and a butterfly including a spherical cap section and two co-axially projecting shafts rotatably mounted in the passages to provide pivotal movement of the butterfly in the body. An annular elastomeric seat member of U-shaped section covers the bore and the outer side faces of the body and the seat receives the shafts of the butterfly and includes at each of the passages a portion of spherical shape substantially complementary to that of the cap section of the butterfly. The seat has a cuff portion surrounding the associated shaft and a support which is independent of the seat bears against the base thereof. The support is constituted of an elastic material housed in an annular groove provided in the body and the support has cuffed portions surrounding the shafts and permanently compressing the spherical portions of the seat against the respective cap portions of the butterfly to assure sealing towards the exterior of the passages for the shafts and, in closed position of the butterfly, the continuity of the sealing upstream and downstream of the butterfly on the seat.
