Problems solved by technology

With this inner and outer matching connection, when the double-layer pipe expands with heat and contracts with cold, the inner and outer pipes can expand and contract independently of each other, so as to solve the problem of pipeline damage caused by the difference in expansion coefficient of the inner and outer pipelines when the double-layer lined pipeline is connected.

Embodiment 1

[0026] For the installation and use of threaded straight-through double-layer pipeline compensation connector, see figure 1 , first push the inner pipe into the outer pipe for a certain length, so as not to affect the hole drilling, and then use a special tool to position and process the hole or hole on the outer circle of the end of the outer pipe, then restore the inner pipe to the original extension length, and then place the installed The nut cover 9a and the brake sleeve 6 with the anticorrosion ring 8 are inserted into the outer circle of the outer pipeline 10 of a double-layer pipeline successively, and then the threaded sleeve 3a and the brake sleeve 6 with the anticorrosion ring 8 and the sealing pipe 2 are housed, Insert the outer circle of the outer pipe 10 of another double-layer pipe successively, and then insert the sealing ring 4, the sealing ring 5, and the sealing ring 4 into the outer circle of the inner pipe 11 of the two double-layer pipes respectively, and ...

Embodiment 2

[0028] The installation and use of bolted straight-through double-layer pipeline compensation connector figure 2 , same earlier outer pipe 10 ends outer circular pipe wall, after positioning processing hole or hole, then restore the original extension length of inner pipe, then, a clamping sleeve 9b with anticorrosion ring 8, brake sleeve 6 1. The overcoat 3b with the sealing tube 2 is inserted into the outer circle of the outer pipeline 10 of a double-layer pipeline successively, and the other clamping sleeve 9b and the brake sleeve 6 equipped with the anti-corrosion ring 8 are inserted into the other successively. The outer circle of the outer pipe 10 of a double-layer pipe is then inserted into the outer circle of the inner pipe 11 of the two double-layer pipes in turn, respectively, with the sealing ring 4, the sealing ring 5, and the sealing ring 4, and then the middle sleeve 1 is inserted into the The outer circles of the two inner pipes 11 are glued with sticky substan...

Embodiment 3

[0030] The installation and use of the threaded elbow double-layer pipeline compensation connector Figure 4 Similarly, after the outer pipe wall at the end of the outer pipe 10 is positioned to process the recess or hole, the inner pipe 11 is restored to the original extension length, and then the nut sleeve 9a and the brake sleeve 6 equipped with the anti-corrosion ring 8 are successively Insert the outer circle of the outer pipe 10 of a double-layer pipe, then stick the viscous substance with the brake nail 7, pass the pipe wall hole on the brake sleeve 6, and position the outer pipe wall hole or the concave hole of the outer pipe 10. In the cave, one end of the curved sealing tube 21 equipped with the middle sleeve 1, the sealing ring 4, the sealing ring 5 and the sealing ring 4 is inserted into the outer circle of the inner pipe 11 and the outer circle of the brake sleeve 6, and then the other pair of Carry out the same operation with the other end of the layered pipeline...

Abstract

A new type double-layer pipeline compensation connector extensively used for double-layer pipeline in producing and conveying high-temp. medium includes such types of straight joint, elbow joint, three-way or four-way joint, and is formed from sealing ring, sealing pipe, sealing loop, brake sleeve, screwed sleeve, nut sleeve, closing sleeve, half-type bend screw sleeve and external cover, half-type three-way or four-way screw sleeve and external cover, and brake nail, screw and nut.

Description

technical field [0001] The invention provides a novel double-layer pipeline connector, which is widely used in the field of double-layer pipeline connection in production and life, especially in the field of double-layer pipeline connection with large temperature changes in production and transport media, and has great significance. Background technique [0002] In the prior art, the connection method of double-layer pipelines is to flang the internal non-metallic pipelines, and clamp and seal the welded flange joints of the external metal pipelines. This connection method adopts negative The method is to shorten the connecting pipe, or perform complex heat treatment, pressure sleeve, metal mesh process and other methods on the inner pipe that cannot completely solve the problem to maintain the connection and use of such pipes. Therefore, at present, this type of pipeline connection has defects such as complex process, high cost, high cost of use, a...
