Pressurized fluid cylinders

摘要

A gas cylinder (100) in the neck (20) of which is installed a balanced valve (26). The valve is fitted in the outlet of the cylinder and its output emerges into a recess (22) which opens to the top surface (23) of the cylinder. Thus the valve is protected from physical damage. A thread (27) in the bore enables the attachment of fittings such as a regulator or a filling device (not shown) which cooperate with the valve (26) to control passage of gas from or into the cylinder.

1. A pressurised fluid cylinder having a neck incorporating an outlet for fluid stored therein, said outlet incorporating a bore in which is fitted a balanced valve, the valve thereby being fitted in the neck of the cylinder such that it does not protrude or minimally protrudes above the neck, and wherein:
the neck is adapted to receive a detachable valve actuator that includes a reaction member, the valve is operable by means of the detachable valve actuator, in which:
attachment of the actuator brings the reaction member into direct contact with a valve member within the balanced valve, moving it in a direction to open the valve and to allow fluid flow through said valve; anddetachment of the actuator removes the contact between the reaction member and the valve member, thereby allowing the valve member to revert to a position at which the valve member seals the valve thereby preventing the contents of the cylinder from escaping.
