Abstract

The invention relates to the technical field of a drainage opening and closing device for a water holding tank on a ship deck, and discloses a water holding tank relief valve, comprising: a valve frame, the valve frame is suitable for being fixedly connected with an oil boom, and the lower end of the valve frame is provided with There is a U-shaped drainage outlet; a valve plate, the valve plate is arranged at the U-shaped drainage outlet, and the valve plate is used to block the U-shaped drainage outlet. , including the valve frame fixedly connected to the oil boom, the lower end of the valve frame is provided with a U-shaped drain port, through which the water in the water holding tank can be emptied. The U-shaped drainage port is blocked, and the first limit components arranged on the left and right sides of the valve plate and the second limit components arranged above the valve plate can press the valve plate, so that the valve plate has a good effect on the U-shaped drainage port. Better sealing effect to avoid oil leakage.

Description

technical field [0001] The invention relates to the technical field of drainage opening and closing devices for ship deck water holding tanks, in particular to a water holding tank relief valve. Background technique [0002] Existing ship decks are equipped with oil booms, and the oil boom and the deck are enclosed to form a water holding tank to prevent the leakage of oil from overflowing and polluting the sea due to equipment or pick-up pipeline failures. Usually, the water holding tank is normal when the equipment is normal. There is no oil in it, but it is rain or waves that cause the sump to fill with seawater. In order to drain water, the usual practice is to set a threaded cock on the oil boom to drain water, but when the threaded cock seat is welded to the oil boom, the height of the weld must be left, so that the water in the water holding tank cannot be drained cleanly, and the ship's Staff experience is poor. SUMMARY OF THE INVENTION [0003] In view of this, ...
