Abstract
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
The present invention relates to a kind of joints of rigid pipes with flexible compensation function.
Background technique
In rigidly connected pipeline, be typically provided with expansion joint, expansion bend or flexible joint, with the compensation caused dimensional changes of reason such as expand with heat and contract with cold; For the convenience of I﹠M, toward the contact meeting some loose joints are set.These component are serially connected in the effect of bringing into play in the pipeline separately, but in some occasion owing to be limited by the limitation of the factors such as function combination and installing space position, such configuration may not be just certain desirable, especially the less pipeline of caliber.Therefore, it is wide to design a installation dimension regulation range, large to line size compensating for variations amount, installs and removes relatively simply, integrates the pipe joint of various functions, is demand urgent in the engineering construction.
Summary of the invention
The present invention can regulate the installation dimension of two end interfaces by a relatively large margin, the function that possesses again loose joint, arbitrarily dismounting, make the installation and maintenance simple and flexible, the lower amount of deformation that again can the auto-compensation pipeline produces because expanding with heat and contract with cold in working order, and be provided with double sealing structure, function and performance are all effectively promoted.It is comprised of adjutage, gland, stuffing box packing, seal ring, fittings body, locking nut, flexible connection nut.Adjutage is a straight-through pipe, and an end cylindrical is established shoulder block, and the other end cylindrical is established the seal groove that seal ring is installed; Gland is an annulus, and internal diameter cooperates with the adjutage crest clearance, can move freely at adjutage, the external diameter of gland then with fittings body on stuffing box packing is installed interporal lacuna cooperate.Fittings body and common tube joint are similar, and it is step-like that profile is, and place, footpath broad in the middle establishes the hexagonal for spanner, outside thread is established at two ends, and the center is through hole, and through hole cooperates with the adjutage crest clearance, can relatively move, an end in hole is established shoulder hole, aperture and the gland Spielpassung that stuffing box packing is installed.The locking nut endoporus is ladder, and the internal thread that is connected with fittings body is established in the large aperture, and the small aperture cooperates with the adjutage crest clearance, and profile is the hexagonal shape.The flexible connection nut inner hole is ladder, and the small aperture cooperates with the adjutage crest clearance, and the internal thread that is connected with pipeline is established in the large aperture, and the adjutage shoulder block is stuck in the place, plane of ladder.Stuffing box packing is the Elastic Circular collar of heatproof, by flexiplastic or rubber manufacturing.Seal ring is the O RunddichtringO, by the temperature resistant rubber manufacturing.Adjutage is penetrated from large aperture end, the small aperture end of locking nut, gland, the stuffing box packing that is flexibly connected nut successively, after being embedded in seal ring, inserts seal groove again the end that fittings body is provided with shoulder hole, locking nut heads into stuffing box packing in the chamber of fittings body shoulder hole against gland, and is tightened on the screw thread of fittings body; Cause be squeezed rear expansive force of stuffing box packing to increase, thereby reach the effect of sealing and locking relative position.During construction, fittings body is connected with the threaded one end of pipeline, unclamps locking nut, allow the flexible connection nut on the adjutage be threaded with the other end of pipeline, when fittings body, be flexibly connected nut and locking nut tightened after ready with the pipeline installation.Such as pipeline is caught a cold, heat affecting produces distortional stress during greater than the frictional force of adjutage and stuffing box packing and fittings body and seal ring, adjutage namely can produce slippage with fittings body, thereby the size that makes with amount of deformation digestion in the present invention, pipeline integral body keeps stable.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is the structure sectional view that the present invention's two end interfaces are internal thread.
Among the figure 1, adjutage; 2, gland; 3, stuffing box packing; 4, seal ring; 5, fittings body; 6, locking nut; 7, be flexibly connected nut.
Embodiment
Adjutage of the present invention (1) is a straight-through pipe, and an end cylindrical is established shoulder block, and the other end cylindrical is established the seal groove that seal ring (4) is installed; Gland (2) is an annulus, and internal diameter cooperates with adjutage (1) crest clearance, can move freely in adjutage (1), and the external diameter of gland (2) then cooperates with the upper interporal lacuna that stuffing box packing (3) is installed of fittings body (5).Fittings body (5) is similar with the common tube joint, it is step-like that profile is, place, footpath broad in the middle establishes the hexagonal for spanner, outside thread is established at two ends, the center is through hole, and through hole cooperates with adjutage (1) crest clearance, can relatively move, one end in hole is established the shoulder hole that stuffing box packing (3) is installed, aperture and gland (2) Spielpassung.Locking nut (6) endoporus is ladder, and the internal thread that is connected with fittings body (5) is established in the large aperture, and the small aperture cooperates with adjutage (1) crest clearance, and profile is the hexagonal shape.Being flexibly connected nut (7) endoporus is ladder, and the small aperture cooperates with adjutage (1) crest clearance, and the internal thread that is connected with pipeline is established in the large aperture, and adjutage (1) shoulder block is stuck in the place, plane of ladder.Adjutage (1) is penetrated from large aperture end, the small aperture end of locking nut (6), gland (2), the stuffing box packing (3) that is flexibly connected nut (7) successively, after being embedded in seal ring (4), inserts seal groove again the end that fittings body (5) is provided with shoulder hole, locking nut (6) heads into stuffing box packing (3) in the chamber of fittings body (5) shoulder hole against gland (2), and is tightened on the screw thread of fittings body (5); Cause be squeezed rear expansive force of stuffing box packing (3) to increase, thereby reach the effect of sealing and locking relative position.During construction, fittings body (5) is connected with the threaded one end of pipeline, unclamp locking nut (6), allow the flexible connection nut (7) on the adjutage (1) be threaded with the other end of pipeline, when fittings body (5), be flexibly connected nut (7) and pipeline and install and locking nut (6) is tightened after ready.
