Definitions

  • the invention relates to devices for dosing fluid or pasty synthetic material, and relates more particularly to such dosing devices for polyol-isocyanate hardening mixtures, or
  • polyol-isocyanateadducts hardening mixtures, as they are used for making homogenous or porous polyurethane.
  • FIG. I is a large scale fragmentary sectional view of a portion of the wall of a mixing chamber with a valve of the membrane type.
  • FIG. 2 is a fragmentary sectional view similar to FIG. I, though on a smaller scale, showing two valves of the membrane type in the wall of the mixing chamber.
  • FIGS. 3 and 4 are sectional views similar to FIG. I, but showing the shifting device as an electromagnetic solenoid and a fluid cylinder, respectively.
  • a wall I of a mixing chamber 13 has conduit means, such as a central recess shown vertically in the drawing, and a feed passage 12 for one of the fluid or pasty synthetic materials, and the passage 12 intercommunicates with the recess.
  • a valve of the membrane type is disposed in the recess.
  • the valve includes a membrane 2 that is composed either of metal, rubber or a synthetic material such as tetrafluorethylene.
  • the membrane 2 is clamped near its external portion between two copper rings 3, and the clamping is sufficiently tight to seal the recess so that any material fed through the passage 12 cannot go above the membrane 2 in the recess.
  • the copper rings 3 are held by means of .bolts 4 within a cylindrical projection of a cover 5, which projection extends into the recess above the membrane 2. In FIG. 2, due to its small scale, the copper rings 3 have not been shown.
  • the valve comprises a valve stem that has a tapered end portion or cone 6, that cooperates with a matching tapered valve seat that is formed in the recess within the wall I.
  • the valve seat terminates at an opening 11 into the mixing chamber, the opening 11 forming a nozzle for the entry of the dosed material into the mixing chamber 13 when the valve is in the open position.
  • the membrane 2 is spaced above said opening 11 fora distance that is greater than the distance between the plane of intercommunication at which the passage 12 intersects the recess and the opening 11.
  • the end of the valve cone 6 In the closed position, the end of the valve cone 6 is substantially flush with the opening 11 as shown in broken lines in FIG. I. In the closed position, the end of the valve cone 6 terminates flush with the internal wall surface of the mixing chamber 13 as shown in broken lines in FIG. 1.
  • Valve actuating means comprise a valve actuator, such as a shifting device 9 that may for instance be an electromagnetic solenoid 14, or an oppositely actuatable fluid cylinder 15, such as a hydraulic cylinder, or an oppositely actuatable air cylinder fed by fluid from conduits l6, 17.
  • the shifting device 9 carries a projection 10 that is in threaded engagement with a metallic body 7.
  • the metallic body 7 includes a protrusion 8 that is in threaded engagement with the interior of the valve stem, and projects through the membrane 2.
  • the opening 11 will be closed by the valve stem, thereby precluding the entry of any material from the recess into the mixing chamber.
  • the movement of the valve stem owing to its connection to the clamped membrane 2, proceeds only for a distance of a few tenths of I millimeter. As long as the valve is in operation, the passage 12 needs not to be closed.
  • valve means may comprise a plurality of valves, each valve being of the type shown in FIG. 1, and each being provided with a valve actuating means such as a valve actuator or shifting device 9 as shown in FIG. 2.
  • Control means may be provided, such as an impact actuator (not shown) in driving connection with the valve actuating means, namely either electric or hydraulic or fluid or mechanical driving connection, so as to actuate all the shifting devices of the individual valves in accordance with a predetermined time schedule in timed relationship, for instance in accordance with a preferred embodiment synchronously.
  • the mixture components will be fed simultaneously and in exact predetermined amounts into the mixing chamber, as each valve is assigned to a specific mixing component namely fluid or pasty synthetic material, a dosed amount of which is to be propelled into the mixing chamber.
  • the impact actuator may be an electric relay.
  • the mixing chamber 13 preferably is provided with an agitating device (not shown), and from the mixing chamber the prepolymer mixture which, in the mixing chamber has been provided with the properly dosed admixtures, will proceed into a mold (not shown).
  • a device for dosing fluid pr pasty synthetic material for use in connection with a walled mixing chamber structure, in combination, said wall defining conduit means, valve means disposed in said conduit means and including valve seat means in said wall, a valve actuating means operable for operating said valve means, and an impulse actuator in driving connection with said valve actuating means and operable to actuate said valve actuating means and thereby said valve means in accordance with a predetermined time schedule, said conduit means defining a first conduit forming a passage for at least one material to be dosed, and a second conduit intercommunicating with said first conduit and defining a recess in said wall, said valve seat means including at least one valve seat formed in said recess and being adapted to form an opening into said chamber, said valve means comprising at least one membrane valve including a valve stem shiftablein opposite directions to and from said valve seat to close said valve seat substantially flush with the interior surface of said walled mixing chamber and respectively to open said valve, a membrane disposed in said reces
  • valve means comprising a plurality of valves, said valve actuating means including a plurality of valve actuators each in driving connection with a valve, said impulse actuator being operable to operate all of said valve actuators and hence said valves in timed relationship.
