THIEF HATCHES WITH DIAPHRAGM ASSISTED SEALING
Thief hatches with diaphragm assisted sealing are disclosed. An example apparatus includes a base attachable to a tank, and a cover attachable to the base via a hinge. The example apparatus further includes a vacuum seal assembly couplable to the cover, and a diaphragm coupled to a stem of the vacuum seal assembly. The diaphragm is moveable in response to a pressure differential between a first pressure within the tank and a second pressure exterior to the tank.
