Definitions

  • the present invention refers to a fluid pressure regulator, and more specifically to pressurized fluid pressure regulators in high pressure equipment that are emptied towards the atmosphere at a given volumetric flow, regardless of the pressure variation in the equipment .
  • High pressure equipment usually called cylinders
  • cylinders are widely use to transport and administer quantities of various industrial and medical fluids according to the requirements of the fluid user.
  • the high pressure cylinders are assembled with multipurpose valve systems .
  • the valve systems are adequate to load or fill the cylinder with fluid, as well as to supply the gas of the cylinder. Additionally, the valve systems are adequate to act as plugs, stopping the supply of the gas. Even more, the valve systems also serve in regards to the security, preventing the sudden variation and/or excessive pressure of the fluid being administered through a pressure regulator.
  • valve systems usually projects in regards to the cylinder, thus subject to deformation and/or rupture during the transport and handling of the cylinder equipment, which could result in the waste of the fluid, and even worse, in the escape of a non-safe product to the environment.
  • the frequent increase of light cylinder use that should only be filled once, i.e. the so called, non- returnable cylinders, or returnable cylinders that should only be filled by an authorized agent increase the several security issues with regards to its re-use or eventual filling, specially in view of the high pressures with which said cylinders are re-filled.
  • the valve comprises a metric valve loaded with a spring, that directly responds to the load pressure as a valve element, that comprises a needle within a control orifice for controlling a low quantity as regulated by a relative voyage through a large conical stem and a main needle valve configured within the output port of the valve nozzle in an end subject to pressurized gas to maintain the valve totally closed, and in the other end wherein said output port is projected for the valve actuation, it is oppressed to initiate flow that ends automatically when said oppression is removed, giving as a result a closed valve by the pressure and action on the end of the pin.
  • US patent No. 5,018,552 discloses a valve assembly for a disposable container that comprises a valve housing that encloses the main valve obstructer, and an auxiliary valve obstructer initially held in an open position by elastic means that unlocks at the end of a first filling, by displacement means of the main valve obstructer beyond its normal opening position under the action of a full lock.
  • the auxiliary valve obstructer is pushed against the seat by a low caliber spring means. Any pressure reduction causes the auxiliary- valve obstructer to open when filling over-pressure may surge against the auxiliary valve obstructer in closed position.
  • 5,467,798 discloses a valve to avoid the filling of a container that comprises a valve body having an input and output and a passage through the valve body interconnecting the input and output.
  • the stem of the valve slides in the passage and has an axial passage that partially extends in a passage extending through the intermediate stem lateral wall to the stem ends .
  • a ball in the stem rests in the stem seat and closes the valve passage against the gas flow towards from the output to the input .
  • a first spring urges a ball against the seat to allow gas flow only in an input to output direction by displacement of the ball from the seat against the action of the first spring in a position of the valve aperture.
  • a second spring urges the stem in the direction of gas flow from input to output, and a seal acts between the stem and the valve body.
  • the second spring urges the seal to a sealed relation with the valve body in a closed position, wherein a coupling is coupled to the valve body, the coupling urges the stem in an opposed direction to the first already mentioned direction and against the action of the second spring to move the seal towards the outside in regards to the seal with the valve body, establishing communication between the input and output when the gas pressure in the entry is sufficient to move the ball outside the seat against the first spring.
  • US patent No. 5,520,214 discloses regulator and fill valve assembly for filling a fluid pressure tank and for regulating the flow of pressurized fluid from the tank includes a regulator portion having a valve body with a piston chamber.
  • a pressure flow passageway extends from an inlet end to a first end of the piston chamber and an outlet port communicates with the piston chamber.
  • a piston is movable in the piston chamber.
  • a first spring at a second opposite end of the piston chamber urges the piston toward the first end of the piston chamber.
  • a handle is provided for manually controlling the force of the first spring acting on the piston.
  • a check valve assembly is located in the passageway and includes a seat, a valve member, a valve guide and a second spring biasing the valve member and guide towards the seat.
  • the valve member is movable in a direction towards a closed position against the seat by fluid pressure in the passageway and the biasing force of the second spring.
  • a valve check actuator is located between the piston and the valve check. Movement of the piston toward the first end of the' chamber tends to move the valve member to an open position.
  • the assembly also includes a fill valve portion having valve body member with a through passageway including another valve chamber open at one end. A restricted flow passage is at the other end of the valve chamber. An outlet opening is connected to the flow passage.
  • the valve body member is connected to the valve body so that a pressure port in the valve body communicates with the open end of the valve chamber.
  • a valving member is slidable in the valve chamber and has a nose that opens and closes the restricted flow passage.
  • a head of the valving member is located in the open end of the valve chamber. Portions establish fluid flow through the fill valve when the restricted flow passage is open.
  • a spring acts on the valving member to urge it toward an open position. Fluid pressure in the pressure port acts on the head and holds the valving member closed until the force of the fluid pressure is overcome by the spring force . The spring holds the valving member open to permit the tank to be evacuated and charged with pressurized fluid.
  • US patent No. 6,230,737 discloses valve assembly having a check valve in a sealing assembly attached to a cylinder, and a detachable dispensing valve matingly fitted with the sealing assembly which actuates the check valve when seated.
  • French patent No. 2634852 discloses a valve for a gas cylinder of the type with expendable packing.
  • a rod with a valve holder is mounted in a valve pusher with the interposition of a compression spring. Initial filling takes place via the passage with a pusher in the raised state.
  • the valve is lowered onto its seat by a handle at, and the rod is broken at and the filling gas source is disconnected.
  • the present invention proposes a valve assembly and a pressure regulator, specially a pressure regulator whose structure is simple, compact and removable, with a low manufacture cost. This allows the user to buy a cylinder without the need that the cylinder be transported and handled with the regulator.
  • an object of the present invention is providing a fluid pressure regulator for high pressure cylinders that is simple, compact and removable, that is easy to assemble and disassemble by the end user.
  • Another object of the present invention is providing a high pressure cylinder that may only be filled by an authorized agent.
  • Another object is providing a pressure regulator for a high pressure cylinder that may have as an object safety during the supply of the fluid, preventing sudden and/or excessive variation of the fluid pressure being supplied.
