A vacuum tank, which is a tank body and a tank lid, the tank lid has a suction device and a gas chamber, the suction device comprises a plunger, and the gas chamber has a plurality of check valves; the gas chamber is disposed in the tank lid, the tank A receiving space is recessed above the cover, and the rod body is inserted into the rod body. The rod body end is pivotally connected to the end of the plunger, and the predetermined portion of the rod body is pivotally connected to the receiving space of the tank lid. The air chamber has a plurality of air inlet holes and a valve hole therein. Each of the check valves is provided, the air chamber is built into the elastic element, and the elastic element is used for pressing the plunger; accordingly, the rod is rotated to drive the plunger to reciprocate in the air chamber, and the gas in the tank enters the air chamber through the air inlet hole. It is discharged from the valve hole, and the original element is restored by the elastic member, so that the lever can be operated with labor and the air can be extracted efficiently.
The vacuum tank comprises a vacuum tube body, a hoisting mechanism and a gantry, wherein the vacuum tube body comprises a tank body and a seat body, and the steel wire rope in the hoisting mechanism is connected to the end of the tank body below the gantry via a pulley mounted on the gantry, Under the pulling of the steel wire rope, the tank body can move up and down and complete the installation with the seat body; the seat body is provided with a sealing gasket, and the bottom flange of the tank body is matched with the sealing gasket, and the weight of the tank body is used. Next, the sealing gasket is compacted to provide a sealing function. The utility model has the advantages of simple structure, convenient operation, multi-stroke switch and mechanical safety device, and improves the overall safety of the device.
