Pipe-end sealing tool

Abstract

The invention discloses a pipe-end sealing tool. The pipe-end sealing tool comprises a sealing part and a fixing part, wherein a sealing plate is used as the seal part, and the fixing part comprises aclamping part and a U-shaped pipe clamp which is matched with the pipe diameter of a pipe. At least three ear plates with kidney-shaped holes are uniformly distributed in the circumferential direction of the sealing plate, a round groove is formed in the inner side of the sealing plate along the edge of the sealing plate, and an O-shaped sealing ring or magnetic ring is arranged in the round groove. The cross section of the clamping plate is in an L shape, through holes corresponding to the ear plates of the sealing plate are formed in the upper surface of the clamping plate, and through holes connected with the U-shaped pipe clamp are formed in the lateral side of the clamping plate; through holes corresponding to the ear plates of the sealing plate are formed in the bottom of the U-shaped pipe clamp, and the upper end opening and the lower end opening in the opening end of the U-shaped pipe clamp are fixedly connected with the clamping plate through connection pieces. The pipe-end sealing tool is easy to use and good in sealing effect, and by means of the pipe-end sealing too, a zinc coating on the surface of a pipe cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of pipe sealing, in particular to a pipe end sealing tool. Background technique [0002] The establishment of black and gray water system piping systems on ships requires a tightness test. Since the pipe ends of the black water system have no flange structure, they cannot be connected by flanges for sealing like conventional piping systems. At present, the commonly used method is to weld the sealing plate or weld two screws to achieve the sealing at the port position. The resulting hot work destroys the galvanized layer on the surface of the pipe system, and the welding operation has safety risks. Therefore, , in view of the deficiencies and defects in the current tightness test of the black water system, a sealing tool suitable for the flangeless structure of the pipe end is designed. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and pr...
