Detailed Description

The invention will be further described by means of an embodiment in conjunction with the accompanying drawings.

Example 1: as shown in fig. 1, 2, 3 and 4, a pipeline pressure testing device comprises a pipe clamp 1, a sealing cover 2, a sealing gasket 3 and a connecting piece 4, wherein the pipe clamp 1 is fixed in a fixing groove of a pipeline 7 close to a port, the sealing cover 2 is connected with the pipe clamp 1 through the connecting piece 4, and the sealing cover 2 is close to the side of the pipe clamp 1 and is provided with the sealing gasket 3.

The pipe clamp 1 includes 1 upper plate of pipe clamp, 1 lower plate of pipe clamp, 1 upper plate of pipe clamp with 1 lower plate of pipe clamp is the same semicircle ring of size, 1 upper plate of pipe clamp and 1 lower plate of pipe clamp constitute the ring and pass through bolt fixed connection, connecting piece 4 is a pipe, pipe one end with sealed lid 2 is sealed fixed, the pipe other end sets up the border, the border respectively with 1 upper plate of pipe clamp, 1 lower plate bolted connection of pipe clamp, 1 upper plate of pipe clamp, 1 lower plate inboard of pipe clamp sets up guard ring 6.

During the use, with pipe clamp 1 upper plate, 1 lower plate clamp of pipe clamp in the fixed slot on pipeline 7, through 1 upper plate of bolt fastening pipe clamp and 1 lower plate of pipe clamp, the guard circle 6 protects 7 surfaces of pipeline not to be destroyed, overlaps the pipe on the 7 mouths of pipe of pipeline and makes sealed 3 and 7 mouths of pipe contacts of sealing on the lid 2, the pipe border pass through the bolt respectively with 1 upper plate of pipe clamp, 1 lower plate of pipe clamp are connected, make the sealed 3 that seal between 7 mouths of pipe of pipeline and sealed lid 2 compressed tightly, seal 7 mouths of pipe of pipeline.
