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.
Claims20
A container comprising:
- a tank;
- a gate coupled to the tank;
- a frame disposed around the gate;
- a locking member that engages the frame around the gate when in a locked position;
- and
- an aperture located in the frame collinearly with the locking member,
- wherein the locking member removably engages the frame within the aperture to apply a biasing force to the gate.
A gate assembly comprising:
- a gate slideable in a first linear direction;
- a locking member disposed adjacent to the gate, the locking member being slideable between a locked position and an unlocked position;
- and
- an aperture located in a frame disposed around the gate, the aperture being located collinearly with the locking member,
- wherein the locking member engages the frame when in the locked position, and
- wherein in the locked position the locking member removably engages the frame within the aperture to apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction.
A sliding gate assembly comprising:
- a gate slideable in a first direction;
- a pin disposed adjacent to the gate, the pin being slideable between a locked position and an unlocked position;
- and
- an aperture located in a frame disposed around the gate, the aperture being located collinearly with the pin,
- wherein the pin engages the frame when in the locked position, and
- wherein, when in the locked position, the pin removably engages the frame within the aperture to displace the gate in a second direction substantially perpendicular to the first direction.
