Definitions

  • the present invention relates to a valve according to the preamble of claim 1.
  • valves are known and are carried by the container.
  • the container has a lid.
  • This lid stamped from sheet metal, is formed with a central projection which defines a coaxial opening.
  • the valve has a valve body which is connected to the projection, a closure part which is arranged displaceably in the valve body and can be actuated from the front of the cover, a sealing element which is arranged between the valve body and the closure part, and a spring element which connects the closure part against the sealing element presses.
  • the sealing member is made of elastomeric material or rubber and comes into contact with the fluid flowing through. As these materials are not resistant to all fluids, the valve can leak.
  • the object on which the invention is based is to provide a valve which does not require such sealing members and whose sealing area is resistant to the fluid flowing through.
  • closure part is essentially cylindrical and if the sealing section has at least one disk-shaped section which projects essentially radially from the closure part. Due to the deformation of the disk-shaped sealing sections that occurs when the valve is closed, a secure tightness can be ensured.
  • the tightness can be further improved by using two sealing sections.
  • the extension is essentially cylindrical and if the extension has a sealing section which comprises at least one disk-shaped section, the section projecting essentially radially from the extension around the valve to seal when inserting.
  • the plastic part is molded onto an essentially circumferentially shaped second section of the container lid, and the U-shaped section has an edge section which is formed in one piece on the inner leg of the section and is essentially parallel to the base of the section and faces inwards extends, this edge section being enclosed by the plastic part in order to seal the valve in a gas-tight manner.
  • the valve comprises a valve body 1 which is integrally formed on the inside of a container lid 2, a closure part 3 which is arranged in the valve body 1, a holding part 4 which is fastened to the valve body 1 and a coil spring 5 which is located between the closing part and the holding part is used.
  • the container lid 2 is a hollow cylinder which has a pre-flanged section 6 on one end for connection to a container edge and advantageously on the other end a substantially U-shaped second section 7 to which the valve body 1 is molded.
  • the U-shaped section 7 has on its inner leg an edge section 23 which is formed in one piece with the section 7 and extends essentially parallel to the base of the section 7 inwards.
  • the container lid 2 is a stamped part and has a central opening.
  • the valve body 1 has a section 8 which protrudes from the inside of the container lid 2 and forms the inlet, and a projection 9 which extends through the opening in the direction of the outside of the container lid 2 and forms the outlet.
  • the valve body 1 encloses the edge section 23, so that a gas-tight seal is achieved in a particularly advantageous manner.
  • the valve body 1 also has a passage bore 10, which extends from the outlet to a section 11 with the valve seat, the seat surface being designed as an inclined surface starting from the through bore.
  • the closure part 3 has a cylindrical body with a flange 13 at one end, a sealing section 14 which is formed adjacent to the flange 13, and four grooves 15 which extend from the sealing section 15 to the other end of the body.
  • the grooves 15 are semicircular.
  • the sealing section 14 is formed by two disk-shaped sections 16 which protrude radially from the body and an extension 17 which is directly adjacent to the flange 13.
  • the holding part 4 is designed as a cap which can be placed on the extension 8.
  • the cap is provided on the edge with a collar 18 and the neck 8 with a groove in which the collar engages.
  • a number of holes 20 are provided in the bottom part 19 of the cap.
  • a recess 21 is provided on the inside of the cap, in which the spring 5 is centered.
  • the spring 5 is held on a shoulder 22 of the closure part 3.
  • valve according to the invention has a second sealing section 24 which is formed on the extension 9 in the region of the outlet.
  • the second sealing section is formed by four disk-shaped sections 25. These sections 25 protrude obliquely outwards from the neck 9 and are directed towards the occasion.
  • the valve In the closed state, which is shown in the right partial section of the figure, the valve is essentially closed by the pressure prevailing in the container (not shown); only when empty Container, the valve is closed by the spring 5 for safety reasons. From this it can be deduced that the closing of the valve to be carried out by the spring 5 can also be effected by at least one elastic section which is provided on the shoulder.
  • the closing part 3 in the valve body 1 is pressed towards the outlet by the pressure, so that the disk-shaped sections 16 come into sealing engagement with the valve seat, the front section 16 in each case being pressed against the seat surface 12 if, as in the present exemplary embodiment, two such sections lie side by side are trained.
  • the deformation of the disc-shaped sections 16 is caused by the fact that the outside diameter of the sections is larger than the inside diameter of the section 11 forming the valve seat according to the invention in the valve body 1.
  • valve seat Another possibility of designing the valve seat according to the invention results from the fact that the section adjoining the seat surface 12 is conical or cylindrical.
  • the closure part 3 of the valve In the open state, which is shown in the left partial section of the figure, the closure part 3 of the valve is displaced by a portion of a spraying device or the like shown in dashed lines against the pressure in the container, so that material can flow out of the container.
  • the second sealing section 24 is brought into sealing engagement with the section causing the opening of the valve in order to prevent fluid from escaping from the container into the lid 2. This also causes contamination by fluid that is difficult to remove, e.g. Prevents polyurethane foam.
