Definitions

  • ABSTRACT A well head is provided with a centrally disposed tubular body that permits the water tight passage of cables connected to a submersed pump.
  • a disc valve that is slidably movable to an open, upper position by means of water pressure and which is also movable to a closed, lower position by the force of gravity, is mounted on the tubular body.
  • Annular seal means are provided between the convex outer edge of a transverse, perforated base that is secured to the body and the concave opposing surface of an annular seat.
  • the most common type of automatic valves used in the well heads is the flap valve type. Said type of valve is opened by the pressure of the flowing water fed by the pump and is automatically closed by the return of water when the pumping action stops. But it occurs that before the closing of the valve, the returning stream acquires a remarkable speed speed and pressure of the returning water mass cause the snap closing of said valve and therefore,at the junction point upstream of the same,inevitable and violent water hammers are generated which cause the well known troubles within the conduits,particularly if frequently repeated.
  • the present invention subject matter is a well head mainly characterized in that it comprises a disc valve with a vertical axis controlled in the direction of opening by the pressure of the water fed by the pump and providing an automatic, instantaneous closing of the outlet ports,due to gravity said valve being mounted axially movable on the skirt of a central bar of the well head which controls the water outlet in a manifold provided with suitable means for the connection to the utilization conduit.
  • the central bar,on whose skirt is movably mounted the disc valve takes preferably the shape of a tubular body passing through the well head in a longitudinal direction,in order to serve as a tube for the passage of electrical cables to feed the pump motor,- while the upper end of same tubular body has a blind bottom,takes the shape of a gripping element in order to permit the lifting of the whole upper part of the tubular body.
  • a further feature of the well head derives from the fact that the disc valve controls an outlet port crown formed at the base of a funnel which with the opposed base forms a flange for the connection to the delivery duct section of the submersed pump.
  • FIG. 1 shows the complete head in a longitudinal section
  • FIG. 2 is a plan partial view from top of same head.
  • FIG. 3 indicates a cover connected to manifold 4 and flange 5 of the tubular jacket 6 by means of suitable bolts engaging the tubular seats 7.
  • the tubular jacket 6 delimits the well diameter and is intended to contain funnel 8 which bears with its base 9 upon the annular edge 10 of manifold 4.
  • the shape of annular edge 10 pre-sents a concavity with a radius R,while the shape of base 9 presents an analogous convexity designed to bear upon base 10. Between the two shapes is provided the insertion of a circumferential packing 1 la.
  • the lower end of funnel 8 terminates with a flange 12 designed to be connected to a correspondent flange of the duct section from the submersed pump.
  • Base 9 of funnel 8 is centrally traversed by the tubular body 13 which is welded to it and closed at its upper end by base 14 provided with holes 15 FIG. 2) for the passage of cables to said base 14 is firmly attached the hook 16 suitable to permit the lifting of the head when the same is detached from flange 5 of jacket 6 or to lift only the internal body when, having removed the cover 3,said body is detached from flange 10 of manifold 4.
  • the tube 13 for the passage of cables protrudes from funnel 8 with its sloping section 13a and contains the electrical cables to feed the motor actuating the submersed pump,leaving the cables out of the water mass passing through the funnel 8 and entering in the direction of arrow x.
  • That base 9 of funnel 8 is further provided with a plurality of delivery ports 17,normally closed by the disc valve 18 located in the cavity A of manifold 4 and longitudinally and slidingly mounted upon tube 13.
  • a stop 19 which is height adjustable and designed to limit the axial movement of valve disc 18. The adjustment of the height of stop 19 is obtained by utilizing the friction of packing 11b. Seal packings indicated by 11 are provided for the sealing of disc valve 18. Another annular packing lie is provided for the sealing between body 13 and cover 3.
  • Manifold 4 is provided with flange 4a,for the connection of head to analogous flange carried by the utilization duct branch for the water extracted from the well.
  • Operation of the well head according to present invention is the following:
  • the water fed by the sumersed pump and pumped within the cavity B of funnel 8 determines with its pressure the lifting of valve disc 18 and discharges through ports 17 in cavity A of manifold 4 and hence through the outlet mouth C of same,feeds the utilization conduit.
  • the pressure of the water fed by the pump within cavity B drops instantaneously down and completely ceases the valve disc 18 lifted by pressure of water from pump,being no longer sustained by the same,falls contemporaneously due to cavity and closes also instantaneously ports 17 preventing any return of the water present in A or in any way returning from the utilization conduit connected to the feeding mouth C.
  • the return of water is prevented and therefore any possibility of water hammers in the interested conduits is also prevented.
  • the annular port for the passage of water which forms between valve disc 18 and flange 9 reduces as the water flow speed decays and closes completely when said speed becomes zero, that is, before the formation of even a minimum value of the reflux water speed.
  • the valve is already completely closed whereby the happening of a water hammer is impossible.
  • a longitudinal vent tube 20 passing through tube 13 completes the head described.
  • An improved well head for use with a submersed pump comprising:
  • a transverse, perforated base rigidly secured to said tubular body intermediate the ends thereof, said base having a peripheral edge positioned in sealing relationship to said seat;
  • a disc valve slidably mounted on said tubular body above said base whereby the pressure of the water delivered by the pump raises and opens said valve
  • said base further includes a funnel-like member extending downwardly about said tubular body, the lower end of said tubular body being sealed and passing through the side wall of said funnel-like member, the upper end of said tubular body including a transverse perforated wall through which the cables of the submersed pump are adapted to pass.
