Definitions

  • the present invention relates to fluid flow shut-off devices and in particular to an emergency, automatic shut-off device for gas cylinder operation.
  • German Specification 2249598 describes a ball valve which is operated if the gas flow becomes excessive.
  • the valve is intended to be operated so that the valve is accelerated upwardly against the force of gravity when the gas flow becomes excessive. There is no consideration given to providing this valve with a shut-off function if it becomes incorrectly oriented. Still further, the various embodiments of this particular device shown and discussed, do not lend themselves to actuation if the device is merely ti 1 ted.
  • a fluid flow shut-off device comprising: a hollow body having an inlet connection portion to be connected to a supply of fluid under pressure, and an outlet connection portion to be connected to an apparatus to receive said fluid, said body providing a chamber through which the fluid passes from a chamber inlet to a chamber outlet, said inlet and outlet being positioned so that fluid entering said chamber enters in a direction having a direction component normal to the
  • a fluid flow shut-off device 10 is connectable to a gas cylinder (not shown) at the inlet end 11.
  • the connection being any convenient means such as snap-on, push-on or screw threaded, connection.
  • outlet end 12 is adapted to be connected to a regulator (not shown).
  • the device 10 has a shaft 13 located in a body 15 adapted to abut a needle valve of the gas cylinder.
  • the body 15 has a further passage 16 sealingly engaged by 0-rings 17 mounted on the shaft 13.
  • the shaft 13 extends to a leading portion 18.
  • the leading portion 18 is engaged and the shaft 13 moved to operate the needle valve of the gas cylinder.
  • the 0-rings 17 divide the passage 16 into, an upstream and a downstream position.
  • the passage 15 communicates with a chamber 19 having an inlet chamber portion 20 and an outlet chamber portion 21. Located in the outlet chamber portion 21 is a ball 22.
  • the chamber portion 21 is of a cylindrical configuration, having its axis normal to the axis of the passage 16.
  • the chamber portion 21 is provided with an 0-ring 23 against which a washer 24 bears.
  • the 0-ring 23 and washer 24 provide an outlet passage 25.
  • the outlet passage 25 is of a smaller cross sectional area than the ball 22, so that upon the ball 22 seating against the 0-ring 23, fluid flow is prevented.
  • Fluid leaving the passage 24 passes through the washer 24 via the passage 25 to an outlet passage 26 to be delivered to the outlet end 12.
  • fluid entering the chamber 21, from the chamber 20, has a direction of travel at least partly normal to the direction of travel of fluid entering the passage 25.
  • a hollow shaft 27 having a central passage 28 extending to the passage 25.
  • the passage 28 communicates with a pressure gauge 29.
  • the shaft 27 is movable in the direction of the arrow 39 so that movement of the shaft 27 can move the ball 22 from engagement with the 0-ring 23 in order to reset the device 10.
  • the ratio of the ball diameter to the diameter of the chamber 21 is. approximately .7.
  • the ball 22 if provided with a weight of about 4.3 gm (about 4.8 mm diameter) co-operates with a chamber 21 diameter of 6.60 mm.
  • a ball 22 having a weight of 4.871 gm (5.40 mm diameter) co-operates with a chamber 21 diameter of 7.50 mm.

Abstract

Dispositif (10) de coupure du gaz pour cylindre à gaz comprimé, qui arrête l'écoulement du gaz depuis le cylindre, lorsque le débit de gaz atteint un niveau excessivement élevé ou lorsque le dispositif est incliné par rapport à son orientation normale. Le dispositif (10) comprend une chambre cylindrique (21) comportant une entrée de gaz (20) et une sortie de gaz (25), avec une bille (22) disposée à l'intérieur de la chambre (21) et servant à fermer la sortie (25) lorsque le débit de gaz atteint un niveau excessivement élevé ou lorsque le dispositif (10) est incliné.
