Definitions

  • the present invention relates to exhaust valves comprising a valve housing, a valve seat formed therein and a valve element supported by movable supporting means for moving the valve element into and out of sealing contact with the valve seat.
  • the invention particularly relates to exhaust valves of this kind for use in the exhaust duct from the engine of a submarine.
  • EP-A-0 226 157 discloses a valve used in lines for liquids containing particles, said valve comprising a valve housing, a valve seat formed therein and a valve element movable in said housing between open position and closed position in engagement with the valve seat.
  • the valve element is connected to a rod which is axially displaceable in a cylindrical sleeve for moving the valve element between open and closed positions.
  • said rod may be rotated to and fro for transmitting said rotary motion to the valve element when the valve elment is in its closed position.
  • One object of the present invention is to provide an exhaust valve of the kind mentioned initially, in which an efficient gringing action on the sealing surfaces between valve element and valve seat is obtained each time the valve is opened and closed, said grinding action being obtained by relative movement between the sealing surfaces, said surfaces simultaneously being urged towards each other by a predetermined pressure force.
  • Another object of the invention is to provide an exhaust valve including means which automatically provides said grinding action and which is simple with respect to its design and which without difficulty may be included into the supporting device used for moving the valve element into and out of engagement with the valve seat.
  • the exhaust valve illustrated in the figures include a substantially spherical valve housing 1 provided with two pipe sockets 2 and 3 respectively connected with the valve housing and extending co- axially with respect to each other.
  • the pipe socket 2 extends a certain distance into the valve housing and terminates into a circular valve seat 4 cooperating with a valve disk 5 which may be brought into engagement with the valve seat.
  • a supporting device 6 which is swingably mounted in the valve housing 1, the valve disk 5 may be swung between closed position as indicated by unbroken lines in fig 1 and open position as indicated by dash-and-dot lines in fig 1.
  • This supporting device 6 includes a shaft 7 rotatably supported in the valve housing 1, said shaft extending within the valve housing 1, through the walls thereof and terminates outside the valve housing.
  • At least one end of said shaft 7 is connected to hydraulic, pneumatic, electrical or other power means, by means of which shaft 7 may be rotated between two angular positions.
  • Shaft 7 is disposed sideways and above the valve seat 4 and extends in parallel with a plane through the upper edge of the valve seat 4.
  • the shaft 7 is rigidly connected with a hub 8 from which an arm 9 extends in the direction towards the valve seat.
  • Supported at the free end of arm 9 is a preferably cylindrical sleeve 10 of annular cross section, said sleeve extending coaxially with the pipe socket 2.
  • a rod 11 of circular cross section is axially displacable in said sleeve 10 and extends through end walls 12, 13 of said sleeve.
  • rod 11 At the end portion of rod 11 extending towards the valve disk 5, rod 11 is connected to the valve disk 5 so that a rotational movement of rod 11 about its own axis is transmitted to the valve disk 5, thus imparting to the valve disk a corresponding rotational movement.
  • the connection between rod 11 and valve disk 5 is obtained by means of a spherical, ball-like member 14 formed at the end of rod 11, said spherical member being provided with two pins 15 extending from the spherical member 14 in opposite directions.
  • the spherical member or ball 14 including the pins 15 is jounaled in the hub 5A of the valve disk 5 so that valve disk 5 will have a certain freedom of movement with respect to the rod 11, but so that when rod 11 is being rotated about its own axis, a corresponding rotational movement is imparted to the valve disk.
  • the rod 11 is provided with a washer 16, rigidly connected to the rod.
  • a compression spring 17 Disposed between the washer 16 and the upper end wall 13 of sleeve 10 is a compression spring 17 which continuously exerts a pressure force on the washer and thus on rod 11 in the direction towards the valve seat.
  • the sleeve 10 is provided with stops 18 disposed on the inner surface of the sleeve above the washer 16, said stops limiting the movement of washer 16 in the sleeve 10 between the bottom 12 thereof and said stop 18.
  • Washer 16 is further provided with grooves, which cooperate with a corresponding number of rims 19 which are rigidly connected with sleeve 10 on the inside thereof between the bottom 12 of the sleeve and said stops 18.
  • the rims 19 extend under a certain inclination with respect to the direction of the central axis of rod 11 and sleeve 10 respectively, so that when rod 11 is being displaced in the axial direction of the sleeve 10, a rotational movement about its own axis is imparted to rod 11 by means of washer 16.
  • the rotational movement is transmitted to the valve disk 5.
  • Axial displacement of rod 11 thus imparts a rotational movement to the valve disk corresponding to the rotational movement of rod 11.
  • valve disk Due to this rotational movement, the valve disk performs a periferal sliding movement along the valve seat, thus exerting a grinding action on the valve seat, and due to this the valve seat is kept free from impurities.
  • the swinging movement of arm 9 is continued until the fully open position of the valve has been reached, as indicated by dash-and-dot lines in fig 1.

Abstract

Soupape d'échappement comprenant un logement de soupape (1) dans lequel est formé un siège de soupape (4), ainsi qu'un élément de soupape (5) supporté par un moyen de support mobile (6) afin de déplacer l'élément de soupape (5) en contact d'étanchéité et inversement avec le siège de soupape (4). Ledit élément de soupape (5) est supporté pour effectuer un mouvement le long d'un axe et pour tourner autour dudit axe par rapport audit moyen de support (6), entre deux positions terminales et à l'aide d'un moyen déformable (10, 11), afin de transmettre à l'élément de soupape (5) un mouvement de rotation autour dudit axe, simultanément avec son mouvement le long dudit axe, de manière à transmettre à l'élément de soupape (5) lorsqu'il est en contact avec ledit siège de soupape (4), un mouvement rotatif par rapport audit siège de soupape (4), après que ledit élément de soupape (5) ait été mis en contact avec ledit siège de soupape (4) et avant qu'il n'en ait été levé.
