Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a seal test device of a tail pipe for a composite sleeve or a porcelain sleeve and a mounting plate thereof, which comprises a water tank 1, a fixed frame 2 and a movable frame 3 which are arranged in the water tank 1, wherein the fixed frame 1 is fixedly arranged at the bottom of the water tank 1, the movable frame 3 is movably arranged on the fixed frame 2, the two ends of the fixed frame 2 are provided with telescopic cylinders 4, the telescopic rods of the telescopic cylinders 4 are connected with the bottom of the movable frame 3, the movable frame 3 can move up and down under the drive of the telescopic cylinder 4, a locking cylinder 5 for fixing a locking mounting plate 13 is arranged above the movable frame 3, a piston cylinder body 6 is fixedly arranged below the movable frame 3, an air inlet 8 is reserved at the bottom of the piston cylinder body 6, the top of the piston cylinder body is hollow, the top of the piston cylinder body penetrates through the movable frame 3, a sealing piston 7 is arranged inside the piston cylinder body 6, and a communication hole 9 is formed in the sealing piston 7.
The utility model discloses in, the top of adjustable shelf 3 still is equipped with the sealed boss 10 that is used for placing mounting panel 13, be provided with the sealing washer on the upper surface of sealed boss 10.
The utility model discloses in, locking cylinder 5 is installed on fast lock fixed frame 11, fast lock fixed frame 11 is fixed on adjustable shelf 3.
The utility model discloses in, the aperture of intercommunicating pore 9 is less than the diameter of air inlet 8, air inlet 8 is connected with outside aerating device through the intake pipe.
