Definitions

  • the invention relates to a control valve for selectively placing under pressure or in a depression an environment or a container, a device for filling or emptying a container and a device for closing a container.
  • the invention relates in particular to container filling and emptying operations, such as for example buckets or pails for transport and/or storage of liquids.
  • the container is usually emptied after the lid has been removed, by tipping the container or introducing therein an aspirating conduit. Even during this container-emptying operation it is not unusual to have uncontrollable spraying and spilling.
  • the aim of the present invention is to solve the problems encountered in the prior art, by providing a device which enables the container to be filled or emptied while drastically reducing the risk of causing uncontrolled spraying or spilling of the liquid.
  • a further aim of the present invention is to provide a device which simplifies and speeds the container filling and emptying operations.
  • the aims of the invention are attained by the control valve for selectively placing an environment or a container under pressure or in a depression, a device for filling or emptying a container and a device for closing a container, according to the appended claims.
  • the control valve 1 of the present invention comprises a body 1a, 1b provided with an inlet opening 2, predisposed for connecting with a pressurised fluid source, and a connecting conduit 3, predisposed for connecting to an environment to be pressurised or depressurised, for example an inside of a closed container.
  • the body 1a, 1b of the valve is made up of at least a first portion 1a and at least a second portion 1b.
  • the connecting conduit 3 develops in a tortuous fashion in part across the first portion 1a, and in part across the second portion 1b of the valve body and in part through a connection 30 positioned inferiorly of the second portion 1b of the valve body.
  • venturi tube is defined internally of the second portion 1b of the valve body, which venturi tube exhibits an inlet section 4, and outlet section 5 and a gully section 6.
  • the various sections of the venturi tube 4, 5, 6 are defined in the following way.
  • a shaped conduit 40 is housed internally of the second portion 1b.
  • the shaped conduit 40 exhibits a narrowing 41, concentrically of which, and internally of the second portion 1b of the valve body 1, an annular chamber 42 is afforded, which is isolated from the surrounding environment by two seal rings 44, 45 arranged at ends thereof.
  • the annular chamber 42 overall defines the inlet section 4 of the venturi tube.
  • the chamber 42 is placed in communication with the outlet section 5 of the venturi tube via a plurality of holes 43 afforded through an annular first end portion 40a of the shaped conduit 40.
  • the holes 43 open onto an annular surface at which the gully section 6 of the venturi tube is located.
  • a shaped obturator 7 is housed internally of the first portion 1a, which shaped obturator 7 is sealedly slidable along a cylindrical seating 70.
  • the connecting conduit 3, the inlet section 4 and the gully section 6 are in communication with the cylindrical seating 70 respectively through a first opening 71, a second opening 72 and a third opening 73.
  • the gully section 6 of the venturi tube 4, 5, 6 is in communication with the cylindrical seating 70 through the shaped conduit 40 and a hole which opens at the third opening 73 through the second portion 1b of the valve body.
  • the shaped obturator 7 is mobile between a central position, a pressurised position and a depressurised position.
  • the inlet opening 2 and the connecting opening 3 are closed.
  • the pressurised position of the shaped obturator 7 is placed in communication with the connecting opening 3.
  • the inlet opening 2 is set in communication with the inlet section 4 of the venturi tube 4, 5, 6, through the second opening 72 and the connecting opening 3 is set in communication with the gully section 6 of the venturi tube through the shaped conduit 40 and the third opening 73.
  • the manual lever obviously any type of servo-command or hydraulic command can be used.
  • the control valve 1 of the present invention is particularly applicable for selective control of filling and emptying a closed container.
  • the control valve 1 can be associated to a lid 102 predisposed to close a container 100.
  • the connecting opening 3 is located such as to be in communication with the inside of the container 100 via the lid 102.
  • An aspiration/discharge conduit 12 can be associated to the lid 102 such as to place the inside of the container 100 in communication with the outside environment.
  • the conduit 12 comprises a first portion 12a, predisposed to be positioned internally of the container 100, and a second portion 12b, predisposed to be positioned externally of the container 100.
  • the first and the second portions 12a, 12b are preferably removably connected to one another by means of a connection 13 which at least partially projects externally of the container 100.
  • the connection 13 comprises a shaped portion 14 which projects externally of the container 100 via the lid 102. This shaped portion is predisposed to receive a closing cap or an attachment element 15, associated to an end of the second portion 12b of the conduit 12.
  • the attachment element 15 preferably comprises two cams, which can be activated in rotation by means of a respective lever 15a, which two cams are mobile between an engaged position, in which they can be arranged internally of an annular groove 14a of the shaped portion 14, such as to constrain the two portions 12a, 12b of the conduit 12, and a disengaged position, in which the two cams are not arranged internally of the annular groove 14a and the two portions 12a, 12b of the conduit 12 are constrained to one another.
  • the pressurised fluid is sent internally of the container 100 such that the pressure internally of the container 100 increases.
  • the increase in pressure pushes the liquid contained inside the container 100 along the conduit 12 in an exiting direction from the container 100.
  • the mouth of the container 12 can be located in a predetermined position, for example internally of a collecting trough for the liquid.
  • a depression is produced internally of the container 100 which recalls a liquid into the container 100 through the conduit 12.
  • the opening of the conduit 12 can be located, for example, internally of a collecting trough for the liquid to be introduced in the container.
  • the control valve 1 preferably comprises a device 8, 10, 11 for detecting the level of a liquid contained internally of the container 100.
  • the device 8, 10, 11 is predisposed to occlude the connecting opening 3 if the level of the liquid exceeds a determined threshold.
  • the detecting device of the liquid level comprises a tubular element 8 which, at an end thereof 8a, is associated to the connecting conduit 3, while at the other end 8b it is open.
  • the tubular element 8 is provided with lateral openings 9 through which the connecting opening 3 can be set in communication with the inside of the container 100.
  • a float 10 is slidable internally of the tubular element 8, which float 10 is provided with a seal element 11 predisposed to be positioned on the connecting opening 3 such as to occlude it.
  • the present invention provides important advantages.
  • the filling and emptying of the container can be done with the container closed, i.e. with the closing lid applied on the container.
  • the risks of eventual sprays or spills of liquid externally of the container are highly limited, if not entirely removed.
  • the container filling and emptying operations are extremely rapid. It is in fact sufficient to connect a pressurised fluid source to the inlet opening 2 of the control valve 1 and displace the shaped obturator 7 into the pressurised or de-pressurised position, by means of the manoeuvring element 20 or other device suited to the task.
