Definitions

  • valve body of the filling head is provided with a circular recess in which a gasket member, made up of a rubber disk element and a lather disk element is inserted, the leather disk element providing the valve seat for cooperating with the seat face of the disk valve element. Since fluids, such as liquid and gas, are flowed through the filling head, at pressures normally in excess of atmospheric pressure, leaks would often occur between the valve seat of the leather disk and the seat face of the disk valve unless the valve seat and seat face were perfectly matched.
  • Another object of the present invention is to provide a method of manufacturing a filling head wherein the valve seat of the packing is formed while the packing is positioned in the valve body.
  • a further object of the present invention is to provide a micro-finish on the seat face of a leather packing or gasket used in a disk valve.
  • leather packings or gaskets used in valves as a seating material were merely finished to have a flat surface, but such a surface ice could be as much as .01 to .015 inch out of parallel with out being detected by the human eye.
  • the present method of finishing the seating surface of the leather packing insures a micro-finish to the surface and, thereby, eliminating leaks between the seating surface of the packing and the cooperating lapped surface of the valve.
  • An anti-friction member 32 is interposed between the nut 30 and the disk valve element 14 so that the seat face 26 of the disk valve element will bear against the valve seat face 24 of valve body 12 with the proper pressure to prevent leaks while permitting rotation of the disk valve element with respect to the valve body.
  • Suitable liquid and gas flow passages 30, terminating in alignment with apertures provided in packing 22, are provided in valve body 12 and are adapted to be aligned or nonaligned with passages in the disk valve element 14 by rotational movement of the disk valve through the several positions shown in Figure 1. For example, if the filling head is utilized on a filling machine for filling containers with beer, the disk valve, when in a position A, is closed and none of the gas and liquid passages 30 are aligned.
  • valve body 12 is provided with an undercut annular groove 34 into which gasket or packing 22 extends.
  • valve stem 28 is provided with an undercut annular groove as indicated at 36, the undercut groove 36 being in ali nment with annular groove 34.
  • gasket 22 also extends into the undercut groove 36 in the completed assembly of the filling head.
  • baking of the gasket and first mentioned element is at a temperature of about 300 F. for about 30 minutes.
  • heating of the gasket and the valve body is at a temperature of about 300 F. for about minutes.
  • a method of forming a seat face in a disk valve of the type having a valve body element and a disk element rotatable with respect to the body element comprising: providing a circular recess in one element for rotatably receiving the other element, undercutting the wall of the recess to provide an annular groove therein, positioning a wax-treated leather gasket of smaller diameter than the diameter of the annular groove into the recess and adjacent the groove, utilizing a lapped surface to firmly hold the gasket in position in the recess adjacent the groove, baking the gasket and element at a temperature sufficient to cause the wax and leather of the gasket to soften and flow to thereby assume the shape of the lapped surface and fill the groove in the recess, and then quickly quenching the gasket and element in cold water to thereby harden the wax and leather of the gasket to its original hardness.
