Definitions

  • the present invention relates to a cylinder valve with integrated pressure regulator.
  • Such valves are known in the art as VIPRs (Valves with Integrated Pressure Regulator) .
  • Such valves are fitted on gas cylinders in order to reduce the pressure from the gas cylinder (often at a pressure of 300 bar or more) down to an outlet pressure, typically below 10 bar.

  • Such cylinders are used to supply gas for a range of applications including welding and cutting hoses and
  • the regulator needs to be adjustable to allow a user to supply gas at the required pressure and flow rate for a given application. For example, different flow rates of shielding gas are normally requires for different material thicknesses during welding processes. Further, the majority of VIPRs need adjusting several times a day to alter the pressure or flow rate as the cylinder pressure drops and consequently outlet pressure increases. Conventionally in a VIPR, the force required to adjust the outlet pressure of the regulator is provided by the application of a manually applied torque rotating a hand wheel. The pressure required is dependent upon the outlet pressure requirements and increases as the outlet pressure increases. This torque demand can often be demanding for the user, particularly when dealing with a high outlet pressure. If the regulator is intended to be operated using an electric motor

  • pilot operated regulators are designed for applications which require a high level of outlet pressure accuracy.
  • the primary drivers of the present invention are to make a small device as it is required to fit on the cylinder and to reduce the torque necessary to operate the regulator.
  • the pilot regulator has a positive seat valve element.
  • the positive seat valve element is one which seats on the low pressure side of its corresponding valve port as opposed to a reverse seat valve which passes through the port and seats on the high pressure side.

The presence of the balancing element allows a smaller package for the pilot regulator.
  • the pilot valve element may be manually operated, in which case it requires less effort from a user to adjust the regulated pressure.
  • the pilot valve element is operated by a motor.
  • the valve may be provided with a means to display one or both of the cylinder pressure and the regulated pressure. However, preferably, it further comprises a single gauge for receiving and displaying both the cylinder pressure and the regulated pressure.

  • An example of a known valve is disclosed in EP 0747796.
  • the improvement provided by the present invention is the introduction of a pilot regulator and the description below will focus on this and the manner in which it interfaces with the regulator and the shut off valve. This will be described, in particular, with reference to Figs. 1 to 4.
