When a floating obstacle occurs on the floating roof, in order to prevent the oil in the tank from flowing back through the central drain pipe to the float valve on the top of the tank, the float ball in the float valve will automatically close the float valve under the buoyancy of the oil in the tank to prevent the oil from overflowing into the tank. top.
The float check valve completely overcomes the disadvantages of the swing check valve. At the same time, the structure is simple and easy to maintain. Wearable parts can be inspected and replaced at any time under working conditions.
