Definitions

  • a valve unit including motor means supporting a plug for reciprocal movement relative to the rim of a collar for regulating the flow of gas from a gas supply conduit, such as an underfloor air cell.
  • the collar is inserted into a sleeve communicating with the gas supply conduit.
  • Quickly detachable coupling means incorporated into the collar and the sleeve permit the valve unit to be quickly connected to and disconnected from the sleeve.
  • This invention relates to improved valve units which are readily attachable and removable, and more particularly to valves of the type described, for use in regulating the discharge of a gas from a gas supply conduit.
  • the present valve is particularly adaptable for use with air conditioning apparatus wherein the valves regulate the discharge of conditioned air into a room for the purpose of maintaining a substantially uniform temperature within said room.
  • such air conditioning apparatus comprises, in part, a pair of air cells conveying air at different conditions. These air cells form a part of a cellular metal subfioor over which is poured a layer of concrete.
  • the cellular metal subfioor and the layer of concrete comprise a floor of the building.
  • the air cells extend to at least one exterior wall and are preferably positioned directly beneath windows provided in the exterior wall.
  • Risers extend through the surface of the concrete to the air cells and serve to communicate the conditioned air from the air cel s into an enclosure commonly known as a mixer box or sill box.
  • the mixer box is provided with an outlet grill through which the conditioned air is discharged into the interior of the room.
  • valves of various constructions have been employed to regulate the discharge of air from each of the risers.
  • These valves have been rigidly secured to the risers, for example, by means of a plurality of fasteners. Consequently, a considerable amount of time and effort is required, on the part of a workman, to properly install each valve. Furthermore, replacement of these valves has been an unduly burdensome and time-consuming job.
  • the present invention seeks to provide an improved valve unit which may be quickly and easily installed and replaced when required.
  • Another object of the present invention is to provide a valve unit of the type described, which is of improved construction and operation.
  • Still another object of the present invention is to provide an improved valve having means for automatically sealing the connection between the valve and an outlet conduit.
  • a further object of the present invention is to provide an improved valve of the type described, having means for compensating for misalignments between the plug and the valve seat thereby insuring complete shut-off of the valve when required.
  • a valve unit having a collar, one end of which is adapted to serve as a valve seat, the other end of which is adapted to be inserted into a sleeve communicating with a gas sup- 3,366,364 Patented Jan. 30, 1968 ply unit.
  • Quickly detachable coupling means is provided for connecting the collar, and hence the valve unit as a whole, to the sleeve.
  • the coupling means is such that connection of the collar to the sleeve is accomplished simply by the fractional rotation of the valve unit about its longitudinal axis.
  • Sealing means also is provided for sealing the connection between the collar and the sleeve.
  • the present valve unit incorporates a plug which is formed from relatively light-gage sheet metal and preferably fabricated by a stamping process.
  • the material of construction used and the method employed to fabricate the plug reduces considerably the overall cost of the plug.
  • the plug has an annular area confronting the valve seat and arranged to correspond therewith.
  • the plug is supported for movement axially toward and away from engagement with the valve seat to regulate the flow of gas out of the valve unit.
  • the plug must, of necessity, be supported in a manner which will permit complete surface engagement to occur between the annular area of the plug and the valve seat.
  • this due to fabricating tolerances, this is not always the case. Consequently, means are provided for compensating for any misalignment between the annular area of the plug and the valve seat. Complete shut-off of the valve unit is thus assured.

  • FIG. 1 there is illustrated a portion of a room 10 of a building bounded by a floor 12, an interior wall 14 and an exterior wall 16 having a window 18 provided therein.
  • the floor 12 consists of a cellular metal subfioor 20 supported on beams 22 of the structural framework of the building, crossover electrical wiring ducts 24 secured to and disposed above the subfioor 20, a layer of concrete 26 overlying the subfioor 20 and the crossover ducts 24, and a decorative floor covering 28 which may comprise, for example, linoleum, tiles and the like.
  • the cellular metal subfloor 20 provides a plurality of cells 30 serving as conduits or raceways for power cables, telephone wires and the like.
  • the cells 30 all extend in one direction with respect to the room while the crossover ducts 24 extend transversely of the cells 30. Consequently, the cells 30 and the crossover ducts 24 serve as a conduit network for distributing the power cables, telephone Wires and the like to various locations in the room 10.
  • the cellular metal subfloor also provides a pair of relatively wide air cells 32, 34 which extend parallel with the cells 30 to the exterior wall 16.

  • the header duct 36 may supply cold air to the air cell 32 while the header duct 38 supplies hot air to the air cell 34.
  • valve units 42, 44 serve to regulate the discharge of cold air and hot air from the air cells 32, 34, by proportioning the flow rates thereof whereby a substantially constant temperature is maintained within the room 10.
  • the control mechanisms for the valve units 42, 44 may comprise, for example, a thermostat 46 mounted on the interior wall 14 at a position remote from the enclosure 40. Extending from the thermostat 46 to the valve unit 42 is a pneumatic conduit 48 containing control air whose pressure level corresponds to the temperature which is detected by the thermostat 46. Within the enclosure 40 there is provided a differential pressure sensing mechanism 50 having a pneumatic conduit 52 extending therefrom to the valve unit 44. The pneumatic conduit 52 contains control air for the valve unit 44 whose pressure corresponds to a differential pressure which is measured Within the enclosure 40. A pneumatic supply conduit 54 supplies control air to the thermostat 46 and to the differential pressure sensing mechanism 50.

  • the differential pressure measured by the two pressure sensing conduits 66, 70 regulates the pressure of control air admitted to.
  • the stream of cold and hot air issuing from the valve units 42, 44 respectively, are blended in-the mixing chamber 68 for discharge through the grill 64 so as to maintain a substantially uniform temperature, for example, 70 F., within the room 10.
  • the thermostat 46 changes the pressure of the control air supplied by the pneumatic conduit 48 to the valve unit 42 so as to effect throttling thereof and a reduction in the amount of cold air issuing therefrom. Simultaneously, the reduction in cold air flow rate from the valve unit 42 tends to cause a drop in the differential pressure across the orifice 60.
  • the reduced differential pressure is sensed by the pressure sensing conduits 66, 70 and, in response thereto, the pressure of the control air supplied by the penumatic conduit 52 changes so as to increase the flow rate of hot air from the valve unit 44.
  • the thermostat 46 will change the pressure of the control air supplied by the pneumatic conduit 48 to the valve unit 42 whereby the flow rate of cold air issuing from the valve unit 42 will be increased.
  • the pressure sensing conduits 66, 70 will sense an increased differential pressure across the orifice 60 and, in response thereto, will change the pressure of the control air in the pneumatic conduit 52 so as to cause a reduction in the flow rate of hot air issuing from the valve 44.
