ABSTRACT:
A cylinder valve insert is used to be mounted within the outlet of a cylinder valve of a cylinder to allow a fluid to pass through the valve when a male fitting is sufficiently engaged with the outlet, and to prevent such fluid flow when the male fitting is separated therefrom. The valve insert includes a body member adapted to be mounted in the outlet; a docking member which is mounted in the body member, has a tapered portion facing away from the normal flow direction of the fluid; a valve member which has a part mounted in the body member and the docking member and movable relative thereto, defines a fluid passage communicating with an open end of the outlet; a sealing member which is mounted surrounding the valve member, is adapted to control such fluid flow from the cylinder to enter into the fluid passage; and a spring which is located between an inner end face of the outlet and the valve member, is adapted to exert a pushing force to push the valve member toward the body member.
