Abstract
A valve mechanism for draining liquid from a container with a pressurized gas. A pipe extends into the container to permit flow of liquid to an outlet. A nut mounts other components of the valve mechanism into the container when the nut is secured in the container opening. A socket releasably connects the pipe and nut whenever the nut is not secured to the container. This allows the pipe, socket and nut to be manufactured separately and also permits replacement of a worn component without having to replace the entire valve mechanism.
Claims12
A valve mechanism, for mounting in an opening of a container, for draining liquid from the container with the aid of a pressurized gas, said valve mechanism operating in conjunction with a connecting piece having a movable gland provided with a bore, an inlet means for inlet of pressurized gas to the container, and an outlet means for outlet of the liquid from the container, said valve mechanism comprising:
- a. pipe means extending into the container, being open at the lower end thereof and closed at the top end, for conveying liquid from the container, said pipe means having apertures formed in the upper portion thereof for the flow of liquid from the interior of said pipe means to the outlet means, and further having a connecting groove formed therein;
- b. a connecting member for insertion into the opening of the container to permit said pipe means to be mounted into the container, said connecting member being movable between a secured position with respect to the container and a released position with respect to the container;
- c. socket means for releasably connecting said pipe means to said connecting member, said socket means having a lower position mounted with said connecting groove of said pipe means to releasably connect said pipe means to said connecting member when said connecting member is in the said secured position, said socket means also having openings therein for permitting the flow of gas into the container;
- d. closing means movable in response to the movement of the movable gland in the connecting piece between a closed position blocking entry of the gas into the container and flow of liquid from the container through said apertures in said pipe means, and an open position permitting entry of gas into the container and flow of liquid from the container through said apertures in said pipe means;
- and
- e. said closing means in said open position establishing communication between the interior of said pipe means and the bore in the movable gland for the passage of liquid from the container, and further forming a separate passageway, having walls formed by said closing means, the movable gland, and said connecting member for entry of gas through said openings formed in said socket means into the container.
