Abstract
An intermediate bulk container, valve and connector system is provided that includes a split nut connector. The split nut connector is rotatably mounted on a valve adapter plate which connects with the valve, and is internally threaded for engagement with external threads on the intermediate bulk container outlet. An O-ring seal is aligned and positioned between the adaptor plate inlet and intermediate bulk container outlet by positioning surfaces to provide compression and sealing between the component engaging surfaces, and sealing contact is provided between corresponding surfaces of the components.
Claims19
An intermediate bulk container with valve and connector system comprising:
- an intermediate bulk container comprising a tank and a pallet;
- a tank outlet at a lower region of said intermediate bulk container, said tank outlet including an outer end and defining an outlet orifice therethrough;
- an outlet annular seal positioning wall extending from said outer end around said outlet orifice;
- a valve assembly operatively mounted on said tank outlet, said valve assembly including an inlet end region defining an inlet orifice;
- said inlet end region comprising a rearwardly facing seal surface;
- an inlet annular seal positioning wall extending from said inlet end region around said inlet orifice;
- said outlet annular seal positioning wall extending from said outer end a distance greater than said inlet annular seal positioning wall extends from said inlet end region and said outlet annular seal positioning wall and said inlet annular seal positioning wall telescopingly mated;
- an elastomeric annular seal positioned between said outer end and said inlet end region and positioned between said outlet annular seal positioning wall and inlet annular seal positioning wall;
- and
- a multipart connector rotatably positioned around and coupling said inlet end region and outer end.
A valve assembly coupling system for intermediate bulk containers having a tank outlet and an outer end with an annular seal positioning wall extending from said outer end around said outlet orifice, comprising:
- a valve assembly adapted to be coupled to the tank outlet, said valve assembly including an inlet end region defining an inlet orifice, said inlet end region comprising:
- a rearwardly facing seal surface;
- an inlet annular seal positioning wall extending from said inlet end region around said inlet orifice said inlet annular seal positioning wall adapted to be telescopingly mated with the outlet annular seal positioning wall;
- an O-ring seal positioned adapted to be positioned between said inlet end region and the outer end and adapted to be positioned between the outlet annular seal positioning wall and said inlet annular seal positioning wall;
- and
- a split ring collar joined by fasteners and rotatably positioned around said inlet end region and adapted to couple said inlet end to the outer end.
