Definitions

  • the invention relates to a valve for attachment to a cylinder for pressurised fluid, such as a gas cylinder.
  • Such cylinders are used to supply gas for a range of applications including welding and cutting hoses and torches, gas packaging machines and laboratory equipment.
  • digital valves on gas cylinders are a recent development in the field.
  • the term digital valve encompasses at least manual valves with electronic sensors, electrically-actuated valves with or without sensors, and valves comprising locating and communication devices.
  • cylinders are often kept in uncontrolled environments in which they may be knocked or damaged.
  • WO 02/12779 A1 and CA 2 389 207 A1 disclose valves for attachment to a cylinder.
  • Embodiments of the valve can provide a convenient base unit having a number of essential components safely housed within the shell of the cylinder.
  • Embodiments of the valve can also provide users with the ability to tailor a valve so as to include only the essential functionality for a particular application.
  • Figure 1 shows a valve 100 for a cylinder 5 in which the valve 100 has a valve body that can be considered as having a lower body portion 20 and an upper body portion 10.
  • the upper and lower body portions 10, 20 may be separate units attached to one another at a junction 19 to form the valve body, or may be notional parts of a single integral valve body, extending outwardly from the junction 19.
  • the upper body portion 10 of the valve 100 includes a port 11 through which fluid may pass.
  • the port 11 is arranged for attachment to external piping, hosing, or valuing.
  • it is shown in Figure 1 as having a threaded section for connection to a corresponding thread on a connector.
  • the lower body portion 20 of the valve is arranged such that it may extend entirely into the cylinder 5.
  • the lower body portion 20 encloses the main components of the valve, namely: a valve inlet 21; a valve member 22; and actuating means 23 for actuating the valve member 22.
  • the actuating means 23 is electrical and is driven by components 24 that are also enclosed within the lower body portion 20.
  • the actuating means 23 may comprise one or more of: a solenoid; a motor; gearing; and/or a linkage.
  • the lower body portion 20 is generally cylindrical in shape.
  • a flange 18 may extend outwardly from the upper body portion 10 at the junction 19 so as to form a stop for abutment with the opening of the cylinder 5 when the lower body portion 20 is fully inserted within the cylinder 5.
  • valve 100 may be used in cylinders already in circulation. However, it may be preferable if the cylinder 5 has an opening of greater diameter than is conventional. Conventionally, the diameter of the opening in the neck of a cylinder is no more than 40% of the diameter of the cylinder body at its widest (perpendicular to its longitudinal axis). It is envisaged that the valve 100 may be used in conjunction with a cylinder 5 having an opening with a diameter of at least 40% of the diameter of the cylinder body at its widest.
  • a flow path extends from the valve inlet 21 in the lower body portion 20 to the port 11 in the upper body portion 10.
  • the valve member 22 is for allowing or preventing a flow of fluid along the flow path.
  • the actuating means 23 is used to actuate the valve member 22 between an open position, in which it allows the flow of fluid along the flow path, and a closed position, in which it prevents the flow of fluid along the flow path. It is preferable that the actuating means 23 provides for variable control of the valve member 22, thereby providing control of the opening degree of the flow path.
  • the valve member 22 may be biased towards a closed position.
  • a spring may bias the valve member 22 towards the closed position.
  • the valve 100 comprises a cylinder engagement means adjacent the junction 19.
  • the cylinder engagement means 15, 25 is for engaging the valve 100 with the cylinder 5.
  • the cylinder engagement means 25 is part of the lower body portion 20.
  • the cylinder engagement means 25 is a generally cylindrical surface of the lower body portion 20 with a male thread formed thereon for engagement with a female thread formed in the neck of a cylinder.
  • the cylinder engagement means 15 is part of the upper body portion 10.
  • the cylinder engagement means 15 includes the flange 18 adjacent the junction 19, along with an annular member extending therefrom (preferably in the direction of the longitudinal axis of the lower body portion 20).
  • a female thread is formed on the annular member for engagement with a male thread formed on the neck of a cylinder 5. This is the only difference between the first and second embodiments.
  • Components 24 housed entirely within the lower body portion 20 include a store of charge 24a; and a wireless receiver 24b.
  • components 24 housed (and preferably entirely enclosed) by the lower body portion 20 further include one or more of: a wireless transmitter 24c; a solenoid 24d; a regulator 24e; a processor 24f; and/or a sensor 24g.
  • the store of charge is preferably a battery or capacitor.
  • the wireless receiver and the wireless transmitter preferably form part of the same device or separate devices and may be arranged to receive and/or transmit by one or more of: bluetooth, UHF, Wi-fi, GPRS, and/or GSM.
  • the sensor is one or more of: a flow sensor; a temperature sensor; a pressure sensor; an accelerometer; a humidity sensor; a moisture sensor.
  • the pressure and temperature sensors are arranged to sense the fluid in the flow path, preferably on the cylinder 5 side of the valve member 22 (i.e. arranged to sense the content of the cylinder 5 irrespective of the position of the valve member 22). However, it may be desirable to position the flow sensor to sense the flow of fluid through the flow path externally (with respect to the cylinder 5) of the valve member 22.
  • a third embodiment of a valve 300 comprises a primary module 110 and at least one secondary module(s) 120, 125, 130.
  • the valve 100 of the first and second embodiments is suitable for use as the primary module 110 of the valve 300 of the third embodiment.
  • the primary module 110 comprises a minimal set of components.
  • the depicted primary module 110 comprises: a port 11 for attachment to external piping, hosing, or valving; a valve inlet 21 for receiving a flow of fluid from the cylinder 5; a valve member 22 for opening or closing the flow path; and actuating means 23 for actuating the valve member 22 between the open and closed positions.
  • these components may be as set out in respect of the first two embodiments.
  • the valve 300 further comprises one or more secondary module(s) 120, 125, 130, detachably connected to the primary module 110.
  • the primary module 110 may be arranged to be connected directly to a plurality of secondary modules 120, 125, 130, whereas in other embodiments the secondary modules 120, 125, 130 may be stacked.
  • the primary module 110 may be arranged to be connected directly to a first secondary module 120, which itself may be arranged to be connected directly to a second secondary module 125.
  • the second secondary module 125 may be arranged to be connected directly to a third secondary module 130.
  • the valve 300 may be formed from a kit of parts comprising a primary module 110 and a plurality of secondary modules 120, 125, 130, in which each secondary module 120, 125, 130 comprises means for attachment to at least two other modules 110, 120, 125, 130.
  • connection between modules 110, 120, 125, 130 may be achieved by any known method achieving both mechanical and electrical connectivity.
  • the primary module 110 may comprise a plurality of spaced recesses, slots or holes.
  • Each secondary module 120, 125, 130 may comprise one or more catches for engaging a recess, slot or hole on the primary module 110.
  • each secondary module 120, 125, 130 may comprise a plurality of spaced recesses, slots or holes.
  • the primary module 110 may comprise one or more catches for engaging a recess, slot or hole on one or more secondary modules 120, 125, 130.
  • the primary module 310 may comprise a recess 312 and a cover 314 for providing or preventing access to the recess 312 (the cover 314 may be a hinged door, or a completely removable cover).
  • the recess 312 may enclose one or more expansion slots 316.
