Definitions

  • the seat comprises a tubular wall, a first end of which forms the sealing ridge, said tubular wall being completely closed at a distance from the sealing ridge by a transverse wall, thus forming the seat cavity
  • One or more longitudinal grooves can be made in the cavity of the valve body so that the product can more easily bypass the seat.
  • the longitudinal groove or grooves preferably extend from the annular passage to at least the lowest position taken, when the valve is in the open position, through the end of the seat opposite the sealing ridge.
  • FIG. 10 An enlarged section of the inside of the valve (a) in the closed position and (b) in the open position.
  • the upper opening of the cavity (11) is closed by a seal (40).
  • the cavity is in direct or indirect fluidic connection with the interior of the container.
  • a cup (50) can be crimped onto the valve body (10) by blocking the seal (40).
  • the valve of the invention is also provided with a stem (60).
  • a pocket (70) can be welded to the valve body (10).
  • the valve body (10) consists of a tubular wall (12) open at both ends which extends, in the assembled state of the valve, around the main axis (A).
  • the interior of the tubular wall defines the cavity (11) of the valve body.
  • the tubular wall preferably has substantially the shape of a cylinder of revolution.
  • a fixing wall (14) is made on the tubular wall (12), below and at a distance from the annular crimping ring (123).
  • This fixing wall surrounds the lower end of the tubular wall (12) and the fixing pin (13). It preferably has a flattened diamond-shaped cross section with the angles of the small diagonals obtuse and rounded, and the angles of the large diagonals acute and more pointed, as can be seen in Figure 3d. This shape facilitates the welding of the pocket (70). If the valve is to be used without a pocket, this fixing wall (14) can be dispensed with.
  • the geometry of the seat must take into account that a sliding movement inside the valve body from top to bottom must be able to allow the valve to open. Conversely, a sliding movement of the seat from the bottom to the top must be done easily inside the valve body to guarantee the rapid closing of the passage windows (612) by the seal (40) and the closing of the valve. to control product distribution.
  • the cup (50) is then placed on and around the annular crown (123) of the valve body with its central opening centered on the main axis (A) and on the central opening (41) of the seal.
  • the cup is then crimped, resting under the annular crown (123) of the valve body.
  • the stem (60) is then introduced by its lower end (61 1) into the cavity (21) of the seat, passing through the central opening of the cup and the central opening (41) of the seal.
  • the stem is then welded to the seat, for example by ultrasound. It would also be possible to make the seat / stem assembly (80) first before assembling the valve.
