The invention belongs to the technical field of medical instruments, and discloses a pressure control device for a pleural effusion drainage tube, which comprises a pressure tank and a sealing cover, the left side and the right side of the sealing cover are fixedly communicated with first air tubes, the top of each first air tube is fixedly connected with a connector, and a connecting tube is movably clamped in each connector. And the middle part of the sealing cover fixedly communicates with a second air pipe. Through cooperation of a supporting plate, a piston block, a second spring, a fixing barrel, a first supporting pipe, a first moving rod and other structures, the device can prevent backflow, after the supporting plate is pulled out, the piston block pops up downwards through the elastic force of the second spring, if the pressure tank accidentally topples, the piston block can be popped up through the second spring, and the pressure tank is prevented from falling off. And through cooperation of a supp
