Abstract
The utility model discloses a pressure sealing device for a trough type oil feeding inlet of an oil tank. The pressure sealing device comprises a lower cover body which is clamped to a clamping opening of the oil feeding inlet. A lower cover body extension which extends out of the oil feeding inlet is disposed on the lower cover body. An upper cover body which is covered on the oil feeding inlet is sleeved onto the lower cover body. A locking nut which locks the upper cover body is connected to the lower cover body extension in a threaded manner. A first sealing device is disposed between the upper cover body and the oil feeding inlet and a second sealing device is disposed between the upper cover body and the lower cover body extension. The lower cover body is provided with an air through hole which communicated inside and outside of the oil tank. A compressed air pipe connector is connected to the outer end of the air through hole. The lower cover body is rotated to a limit of the trough type oil feeding inlet through the clamping opening of the oil feeding inlet and a rotary clamping handle. Sealing of junction surfaces is achieved by the aid of the first sealing device and the second sealing device. By the aid of the compressed air pipe connector connecting to the outer end of the air through hole, sealing tests can be performed to the oil tank conveniently, time is saved, and convenience to use and fine sealing performance are achieved.
