Definitions

  • ABSTRACT is positioned in the space between the washer and the bolts and abutswith one edge against the outside of the washer and with the other edge against the bolts.
  • the present invention relates to a means for sealing between a container and a lid on top of it which projects slightly outside the walls of the container.
  • the invention is characterized in that on the outside of the container, and at a certain distance from its upper edge, a frameis placed around the container and in the groove formed between the frame and the part of the lid projecting outside the container a washer of plastic material is arranged nearest the container and a resilient support strip located outside the washer which abuts the washer with one edge and with the opposite edge abuts a number of bolts which pass through the lid and frame, a
  • the wall of the transformer tank is designated 1 and' the lid 2.
  • the lid projects outside the wall of the tank a little way.
  • On the wall of the tank and at a certain distance from its upper edge is attached a frame 3 enclosing the tank.
  • a number of holes 4 are drilled through the part of the lid lying outside the tank and through the frame, uniformly distributed around the circumference of the tank.
  • Bolts 5 are arranged in the holes, each having a nut 6.
  • a washer 7 of plastic material In the groove between the wall of the tank, the lid and the frame is a washer 7 of plastic material. Between the washer and the row of bolts 5 is a resilient support strip 8 this being inserted so that its lefthand side in the drawing abuts the washer whereas its righthand edge abuts the bolts.
  • the height of the washer 7 is chosen so that it substantially completely fills the groove between the lid and the frame, while the height of the support strip is somewhat less.
  • the washer 7 will then be deformed and fill any spaces between the upper edge of the tank and the lid-and also will intrude into the spaces between'the frame and support strip and between the lid and the support strip. Since the support strip is resilient, it will to a' greater or lesser extent be pressed out between the bolts as the lid and frame are drawn together. This means that the washer is continuous 'under a certain pressure and this means that the seal between the wall of the tank and the lid is maint'ained even if the volume of the washer alters somewhat because of temperature alterations.
  • the invention also makes it easy to machine the,
  • the frame 3 is suitably attached to the tank by means of welding with its upper edge at a certain distance from the upper edge of the tank 1 before the upper edge is machined, this distance being at least as great as the final distance between the frame and the lid is to be.
  • the upper edge of the tank is cut to the correct measurements with the help of a cutting torch movable on the upper side of the frame 3.
  • the distance between the upper side of the frame and the lower side of the lid is then well-defined when the lid is placed on the tank.
  • the area of the washer 7 should exceed the area of the groove intended for the washer between the box wall 1, lid 2, I
  • a lid (2) arranged above the container and projecting out from the walls of the container, a frame (3) secured on the, outside of the container spaced from its upper edge and surrounding the container, forming a groove between the frame and the part of the lid projecting outside the container,
