Embodiment Construction
[0008] The regulating pipe (1) of the present invention is a straight-through circular pipe, with a shoulder on the outer circle of one end, and a sealing groove for installing the sealing ring (4) on the outer circle of the other end; (1) The outer diameter is clearance fit, which can move freely on the adjustment tube (1), and the outer diameter of the pressure sleeve (2) is matched with the hole clearance of the sealing packing (3) on the joint body (5). The joint body (5) is similar to ordinary pipe joints, with a stepped shape, a hexagon for a wrench is provided at the large diameter in the middle, external threads are provided at both ends, and a through hole is formed in the center, and the through hole is in clearance fit with the outer diameter of the adjusting pipe (1) , can be moved relatively, one end of the hole is provided with a stepped hole for installing the sealing packing (3), and the hole diameter is matched with the pressure sleeve (2). The inner hole of t...

The invention provide a rigid pipe joint with the telescopic compensation function, which can adjust the mounting sizes of ports at two ends by a larger margin and has the function of flexible connection, so that the rigid pipe joint can be detached freely, the installation is simple and flexible, the deformation due to expansion caused by heat and contraction caused by cold can be automatically compensated under a work state, and the rigid pipe joint is provided with double seal to enable the performance to be more reliable. The rigid joint comprises an adjusting pipe, a pressing sleeve, sealing filler, a joint body, a locking nut, and a flexible connection nut. The adjusting pipe penetrates the flexible connection nut, the locking nut, the pressing sleeve and the sealing filler sequentially, then is embedded into a sealing ring, and is inserted into a step hole end of the joint body; the locking nut is propped against the pressing sleeve to push the sealing filler into the cavity of a step hole of the joint body, and is tightly screwed onto the joint body, and the sealing filler is extruded to increase the expansive force, so that the functions of sealing and locking the relative position are achieved. During the construction, the joint body is connected with one end of the pipe, the locking nut is loosened, the flexible connection nut is connected with the other end of the pipe, and after the join body, the flexible connection nut and the pipe are mounted in order, the locking nut is tightened.
Description
technical field [0001] The invention relates to a rigid pipe joint with expansion and contraction compensation function. Background technique [0002] In rigidly connected pipelines, expansion joints, expansion joints or flexible joints are usually provided to compensate for dimensional changes caused by thermal expansion and contraction; for the convenience of installation and maintenance, some live joints are often provided. The series connection of these parts plays their respective roles in the pipeline, but in some occasions, due to the limitations of functional combination and installation space location, such a configuration may not necessarily be ideal, especially for pipes with small diameters. road. Therefore, it is an urgent need in engineering construction to design a pipe joint with a wide range of installation size adjustment, a large amount of compensation for pipe size changes, relatively simple assembly and disassembly, and a combination of many functions. ...
