초록 ▼

A limited restriction quick disconnect valve preferably for mounting between a container, like that involved in medical instrument sterilization system, and a transfer line for passing a sterilization agent thereto. The valve is for mounting at a bulk head female connector section into the container wall and includes a stem with side ports formed therein that intersect a passage that is open to within the container, the stem for receiving, as a closure device, a resilient sleeve fitted, in sealing arrangement, thereover. A closure ring section, that is connected to the transfer line, is provided for fitting onto a retaining ring of the bulk head female connector. The closure ring section includes a cylindrical shaft that is arranged axially therein that includes a forward end for engaging and compressing the resilient sleeve when the coupling ring is fitted onto the retaining ring, the resilient sleeve when compressed to bow outward around its mid portion, lifting the sleeve interior surface off from and opening the side ports, providing a passage from the container to the transfer line. For cleaning after use, the resilient sleeve can be pulled off the stem and replaced with another resilient sleeve and the interiors of the bulk head female connector and coupling ring section are open, have no moving parts, for facilitating cleaning.

대표청구항 ▼

A limited restriction quick disconnect valve comprising, a bulk head connector section that includes a mounting device, with means for securing it to a flow receiving arrangement as a valve forward end, that has a cylindrical segment extending axially from a rear surface thereof that includes a means for mounting a retaining ring thereon and is stepped inwardly into a stem that extends axially from a rear face of said cylinder segment, with a center longitudinal opening formed from said mounting device into said stem, and at least one side port formed into said stem to said center longitudinal opening; a retaining ring that includes, on its interior surface, a means for coupling said retaining ring onto said cylindrical segment, and includes a means for receiving and coupling to a coupling ring section fitted thereover; a keeper means, for mounting in said retaining ring, that is centrally open and includes means for retaining a resilient sleeve as a valve closure device on said stem within said retaining ring; a resilient sleeve; and a coupling ring section that is a cylinder with a coupling ring formed on a forward end, said coupling ring including means for fitting into and coupling to said retaining ring means, for coupling them together, and is stepped inwardly into a cylindrical center section that terminates in a means for pivot connection to a cylindrical plug; a cylindrical plug that is open longitudinally therethrough and includes pivot coupling means formed around a plug center portion that is for receiving, as a sealed pivot coupling, said coupling ring means for pivot connection to said plug pivot coupling means, said plug including a cylindrical shaft extending axially from said plug forward end that has a diameter to fit through said keeper central opening and has a forward face for engaging and compressing said resilient sleeve end when said coupling ring is joined to said retaining ring, and said plug rear end includes a means for receiving a transfer line mounted thereto.
