Abstract
A manway gate assembly couples to a tank and provides a liquid tight seal. The manway gate assembly includes a gate selectively slideable in a first linear direction between an open position, a closed position, and/or an intermediate position between the open position and the closed position. The manway gate assembly includes one or more locking members arranged adjacent to the gate and moveable between a locked position and an un-locked position. When in the locked position, the one or more locking members apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction to seal the gate to the tank and provide a liquid tight seal.
Claims17
A container comprising:
- a tank for holding a product;
- and
- a gate assembly coupled to the tank, the gate assembly including:
- a gate slideably disposed in a first plane adjacent to a surface of the tank, the gate to slideably displace in the first plane along the surface of the tank between an open position and a closed position;
- one or more locking members having a longitudinal axis disposed in a second plane parallel to the first plane, the one or more locking members slidable in the second plane parallel to the first plane between a locked position and an un-locked position, wherein the one or more locking members engage a frame arranged around the gate when in the locked position;
- and
- one or more apertures located in the frame collinearly with the respective one or more locking members,
- wherein the one or more locking members removably engage the frame within the respective one or more apertures to apply a biasing force to the gate in a direction perpendicular to the first and second planes to seal the gate to the surface of the tank in the locked position.
A gate assembly comprising:
- a gate to selectively slide in a first linear direction;
- one or more locking members slideably arranged adjacent to the gate, the one or more locking members being slidable between a locked position and an un-locked position;
- and
- one or more apertures located in a frame arranged around the gate, the one or more apertures being located collinearly with the respective one or more locking members;
- wherein the one or more locking members engage the frame when in the locked position, and
- wherein in the locked position the one or more locking members removably engage the frame within the respective one or more apertures to apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction.
A gate assembly comprising:
- a gate to selectively slide in a first linear direction;
- one or more pins slideably arranged adjacent to the gate, the one or more pins to slideably displace between a locked position and an un-locked position;
- and
- one or more apertures located in a frame arranged around the gate, the one or more apertures being located collinearly with the respective one or more locking members;
- wherein the one or more pins engage the frame when in the locked position, and
- wherein, when in the locked position, the one or more pins removably engage the frame within the one or more apertures to displace the gate in a second linear direction perpendicular to the first linear direction.
