Definitions

  • the present invention relates to a lateral sealing device between a check valve and its casing.
  • a valve is an element having in cross section the approximate shape of an airplane wing and which swivels longitudinally either to let the water pass when it is oriented horizontally, or to retain it when it stands at vertically or obliquely.
  • the valves considered comprise a longitudinal seal fixed to the threshold of the dam, the lip of which cooperates with the leading edge or "bordered" on the valve.
  • On either side of the latter there is provided a seal which provides lateral sealing with the corresponding bajoyer.
  • Each seal has a lip arranged over the entire length of each lateral face of the valve and a rounded rib corresponding to the leading edge or "plating" and which makes it extends so as to come to bear by its lateral edge against the bajoyer.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a seal intended for the lateral sealing of a check valve and the effectiveness of which does not depend on expansions or contractions of it.
  • the seal used in the sealing device according to the invention comprises a rounded rib which protrudes transversely beyond the plane containing the free terminal edge of the oblique wing of the lip to form a circular periphery, while the bajoyer is provided with a cylindrical recess against the peripheral wall from which said periphery of the rounded rib comes to bear.
  • the rounded rib partially engages under the corresponding end of the planking and extends beyond it by being flush with the lateral face of said plating.
  • the illustration in fig. 1 shows the concrete threshold 1 of a dam with respect to which is mounted a valve 2 established in the usual way in the form of a box having in cross section the rough shape of an airplane wing.
  • This valve is articulated around a shaft 3 extending along the threshold 1 and the pivoting movement of which is controlled by a hydraulic cylinder 4.
  • the valve can take the position illustrated in solid lines by extending the threshold 1 to allow the passage of water from upstream to downstream.
  • the actuator 4 By expanding the actuator 4, the valve 2 is placed in the position illustrated in broken lines for which it is substantially vertical in a water retaining position.
  • the part 2a of the valve which surrounds the shaft 3 is called in the usual technique the "plating".
  • the threshold naturally presents a step 1a allowing the clearance of the plating 2a.
  • a profile 5 (Fig. 2) fixed to the vertical part of the recess 1a and to which is attached a seal 6 whose free end cooperates with the plating 2a to ensure the seal in the longitudinal direction.
  • the valve 2 is mounted between two casings 7 which each constitute the vertical side walls of the threshold 1. Each casing 7 is coated with a sheet 7a.
  • a seal 8 (fig. 4) comprising a lip 80 having in cross-section the shape of an open angle iron coming from a block 81 from which a rounded rib 82 opposite the lip 80.
  • the oblique wing 80a of lip 80 has a terminal edge lying in the same plane as that of side 82a of rib 82.
  • the latter has a recess 82b which engages under the plating 2a of valve 2. illustrated in fig. 5, the remaining part of the periphery of the rib 82 is in the plane of the plating 2a.
  • the rib 82 considered is assembled to the plating 2a by means of a plate of the same shape 9 which sandwiches the rib considered relative to the plating 2a by means of assembly bolts. It is observed that the lip 80 is supported by a bar 2b which stands perpendicular to a core 2c of the valve 2 oriented normally to the plating 2a. A profile 10 allows the subjugation of the lip 80 relative to the bar 2b.
  • the periphery of the rib 82 adjacent to the recess 82b is flush with the lateral face of the plating 2a, while its lateral edge 82a bears against the sheet 7a of the bajoyer 7.
  • This rim 110 is also provided with a step 112a in which the plating 2a engages, said periphery 112 flush with the outside of said plating as illustrated in FIG. 8.
  • a plate 12 which conforms to the internal shape of the rib 110 and which is situated under the plating 2a so that the step 112a is sandwiched between the latter and said plate.
  • Fixing bolts 13 provide general assembly.
  • the flat profile referenced 14 (fig. 8), which corresponds to that 10 of the embodiment of fig. 1 to 5, is extended by a rounded part 14a cooperating with the external surface of the rib 110, under the plating 2a.
  • Bolts 15 thus make it possible to secure said rib relative to plate 12.
  • a lateral valve seal was thus produced which, when it is lengthened or narrowed under the effect of heat or cold, continues to ensure perfect sealing since the periphery 112 of the rib 110 of the joint 11 moves by sliding against the cylindrical peripheral wall of the recess 7b, avoiding any leakage since there is a sealing face parallel to the direction of movement of the valve.
  • this seal is effective whatever the angular position of the valve due to the cylindrical shapes of the recess 7b and the periphery 112 which of course has the same radius.
