Definitions

  • the present invention concerns a new or improved device tor closing the discharge orifices of tanks and like containers, such device being especially useful for mobile liquid containing tanks, such as tank wagons, tank lorries and barges.
  • This cap has the disadvantage that it comprises two detachable members and a number of bolts which are likely to fall from the vehicle in the course of delivery operations and may be lost. Use of this cap complicates the operators task.
  • no device is provided to prevent the sealing flange of the degassing pipe from being violently blown off if the closure device remains closed when the tank is under pressure, or to prevent the spraying of droplets of corrosive liquid onto the walls, such drop-lets then being entrained by escape of vapours under pressure.
  • FIGURES 1 and 2 are respectively a vertical section and a half plan view in diagrammatic form of this embodiment of closure device according to the invention, the
  • FIGURE 1 is on the line A-A of FIG- 7 URE 2;
  • FIGURE 3 is part of the section of FIGURE 1 on an enlarged scale and showing the details of the bolt, nut and lock nut assembly.
  • the flanged discharge pipe of the tank is indicated by the reference 1. Over this is arranged a dome comprising a cylindrical portion 2 closed at the top by a cover 3 which has a peripheral flange pressed on to a gasket or packing by downward pressure on the cover produced by a double beam 4 pivotally mounted at one end on a fixed pin and supporting at the other end, by means of journals 17 a sleeve member 6 formed with a vertical cylindrical hole (see FIGURE 3).
  • the said hole receives a cylindrical nut member 7 which is held captive to the sleeve member by means of a screwed detachable abutment collar 8.
  • the nut member 7 has secured to its upper part a locking hand wheel 9 and carries therebelow a lock nut provided with a hand lever 10.
  • the member 7 is further formed with an axial bore, which is internally threaded only at its upper part which is of reduced diameter. Screwed into this portion is an eye bolt 11 pivotally mounted on a fixed pin 12 carried on a bracket projecting outwardly from the portion 2.
  • the packing of the cover 3 of the dome is secured to the flange of the cover by the inner marginal portion of the packing being clamped between the flange and a metal ring secured to the latter by screws.
  • the discharge pipe 1 is maintained in position by a plate 13 gripped between an annular flange 1d situated at the bottom of the cylindrical portion 2 of the dome and a corresponding flange on the tank on which the cover is provided.
  • the plate 13 is in addition formed with a number of apertures 15 affording a permanent communication between the tank and the interior of the dome.
  • the apertures 15 are each provided with a grille to prevent any bolts which may be dropped when bolting a flexible pumping pipe to the discharge pipe from falling into the tank.
  • An annular downwardly directed flap 16 surrounds the peripheral flange of the cover 3.
  • This assembly comprises no parts which can be involuntarily detached and in addition affords complete safety to the operator undertaking the delivery.
  • the essential feature of the device according to the invention is that this is in the form of a single unit which acts as a closure for both the discharge pipe and the orifice for connection to the atmosphere and which is operated by means of a single robust clamping means of a form which can only be released gradually and which has no removable parts.
  • the closure device according to the invention may be constructed of any material compatible with the liquid to be carried,,and may either be constructed entirely of one material or consist of a material covered with an appropriate coatin Likewise, the packings are so chosen as to resist the action of the said liquid or of its vapourl.
  • a closure device for a discharge pipe on a tank adapted to contain liquid comprising a dome secured gas tightly on the tank and formed by a base portion surrounding both said discharge pipe and-also at least one orifice in the tank communicating the, interior of the tank with the interior of the dome and by a cover portion movable relatively to said base portion to and from a closed position in which said cover portion sealingly closes said base portion over said discharge pipe and-orifice, the improvement comprising, for releasably clamping said cover portion to said base portion in said closed position of the coverportion, a double beam pivotally carrying said cover portion, means mounting said beam for pivotal movement relatively to said base portion, a sleeve pivotally mounted on said beam at a position remote from said means mounting the beam, said sleeve having a bore therethrough, a nut carried captively, but rotatably, in'said sleeve bore, means on said nut for rotating the latter and a bolt pivotally mounted on said base portion
  • closure device specifiedin claim 1 and including a lock nut threaded on said nut so as to be clampable against said sleeve.
  • a closure device for a discharge pipe on the tank comprising:
