Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 and 2, the embodiment of the utility model provides a pipeline with interim protect function, pipeline includes pipeline body 1, pipeline body 1 mainly used steam or hydrothermal transport, cup joint on the outer pipe wall of pipeline body 1 the protection tube, the protection tube with leave the space between the pipeline body 1, the both ends of protection tube are passed through sealed fixing device fixed seal.
Specifically, the sealing and fixing device comprises an inner sleeve 3 and an outer sleeve 4, the inner sleeve 3 is sleeved on the outer pipe wall of the protection pipe and is in threaded connection with the protection pipe, and the outer sleeve 4 is sleeved on the inner sleeve 3 and is in threaded connection with the inner sleeve 3.
The sealing rubber ring 5 is also arranged in the inner sleeve 3, a mounting hole 32 is circumferentially arranged on the pipe wall of the inner sleeve 3, a movable wedge block 6 is arranged in the mounting hole 32, wherein, the movable wedge block 6 is provided with an action bottom surface which is abutted with the outer ring surface of the sealing rubber ring 5 and an action inclined surface 61 which is abutted with the outer sleeve 4, thus when in use, when the outer sleeve 4 is twisted on the inner sleeve 3, the end of the outer sleeve 4 is in contact with the action inclined surface 61 of the movable wedge 6, and applies a force to move the movable wedge 6 towards the inside of the inner casing 3 and to press the sealing rubber ring 5 through the bottom of action, so that the sealing rubber ring 5 is pressed against the conveying pipeline, so that the gap left between the protective pipe and the pipe body 1 constitutes a sealed chamber. Meanwhile, in order to further improve the sealing effect, a clamping groove 31 is arranged in the inner sleeve 3, and the sealing rubber ring 5 is arranged in the clamping groove 31 and is connected with the groove wall of the clamping groove 31 in a sealing manner. When the position of the protection tube needs to be adjusted, the outer sleeve 4 is twisted down, the acting force on the sealing rubber ring 5 is released, and therefore the inner sleeve 3 is moved, and the position of the protection tube is adjusted.
Further, in the present embodiment, the number of the mounting holes 32 is at least four, and the mounting holes are uniformly circumferentially disposed on the wall of the inner sleeve 3. The sealing rubber ring 5 can be tightly and hermetically connected with the inner sleeve 3 through acting forces in four directions.
