Abstract
The utility model discloses new pipe series without screw thread used for the connection of pipe passages of petroleum, chemistry, coal gas, and water heating; the pipe series can be directly used for installation, and screw thread doesn't need to be made on the pipe; a sealing ring and a heart-shaped locking ring are arranged between a main body and a press cover; the outer wall of the main body and the inner wall of the press cover are provided with screw thread; during the installing time, the press cover can be rotated to achieve the purpose of pipe passage connection. The utility model has the advantages of simple operation and maintenance, convenience, high installation speed, low labor intensity, and wide application range.
Description
The utility model is a kind of novel pipe fitting that pipelines such as being used for oil, chemical industry, coal gas and hot-water heating connects that relates to.
The pipe fitting that uses in the pipeline fitment process at present needs manually in tube wall upper plate system screw thread or welding, labor intensity is big and work efficiency is low, and is especially very inconvenient when maintenance, the expense height.
This practical task is: design a kind of pipeline that is directly used in and install, promptly on tube outer wall without plate system screw thread, on the basis of existing screw-thread-free pipe spare, further strengthen the sealing lock ability, and be beneficial to the raising installation efficiency, the heart self-locking series pipe fitting of convenient for maintaining.
" heart self-locking series pipe fitting " provided by the utility model, it includes main body (1), gland (2), heart retainer (3), seal ring (4) and rectangular seal (6) and forms.It is characterized in that: heart retainer (3) outer wall is cylinder circular cone scalariform, on its taper, have notch, inwall has teeth patterning or does not have teeth patterning (pipeline according to different pressures requires to decide), the inwall of main body (1) is cylinder circular cone scalariform, its termination outer wall is provided with screw thread, and this termination inwall port is the outer cone shape, and gland (2) inwall is cylinder circular cone scalariform, be provided with screw thread at the one end head inwall, another termination inwall is the female cone shape.Be disposed with heart retainer (3) and seal ring (4) between main body (1) and gland (2) inwall, be provided with rectangular seal (6) in main body (1) inwall.
The utlity model has following advantage: it is widely applicable, and lock sealing intensity height is specially adapted to pressure duct, has the installation efficiency height, and labor intensity is little, and maintenance is convenient, advantages of simple operation.
Accompanying drawing 1 is the assembly structure generalized section of the utility model heart self-locking series pipe fitting.
Accompanying drawing 2 is the part section enlarged view of the assembly heart retainer (3) of the utility model heart self-locking series pipe fitting.
Accompanying drawing 3 is that the A of assembly heart retainer (3) of the utility model heart self-locking series pipe fitting is to view.
To describe embodiment in detail in conjunction with above accompanying drawing:
Heart self-locking series pipe fitting as shown in Figure 1, its critical piece includes main body (1), gland (2), heart retainer (3), seal ring (4) and rectangular seal (6) and forms.It is characterized in that: heart retainer (3) outer wall is cylinder circular cone scalariform, on its taper, have several notches, its inwall has teeth patterning or does not have teeth patterning (pipeline according to different pressures requires to decide), the inwall of main body (1) is cylinder circular cone scalariform, its termination outer wall is provided with screw thread, this termination inwall port is the outer cone shape, gland (2) inwall is cylinder circular cone scalariform, be provided with screw thread at the one end head inwall, another termination inwall is the female cone shape, is disposed with heart retainer (3) and seal ring (4) between main body (1) and gland (2) inwall, be provided with rectangular seal (6) in main body (1) inwall.In pipeline installation and maintenance process, earlier rectangular seal (6) is inserted main body (1) inwall, then successively with gland (2), on heart retainer (3) and the outer wall of seal ring (4) through pipe (5), pipe (5) is inserted among the inwall of main body (1), pipe termination and rectangular seal (6) are close to, again with seal ring (4), the inwall that heart retainer (3) is inserted main body (1) successively, rotating gland (2) at last docks with main body (1) and screws, because of screw thread rotation produces axial pressure, heart retainer (3) outer wall two conical surfaces are subjected to the extruding of gland (2) and main body (1) inwall conical surface, force it to hold pipe tightly, in axial motion, heart retainer (3) is crush seal circle (4) again, because of the heart retainer to the holding tightly of pipe, drive pipe extruding rectangular seal (6) during axial motion again, two seal rings (4), (6) because the pressurized lateral expansion, play seal action, thereby reach the purpose of connecting pipeline.
Claims (1)
1, a kind of novel pipe connector that is used for the pipeline connection, it includes the heart retainer, seal ring, main body and gland are formed, it is characterized in that: described heart retainer (3), its outer wall is cylinder circular cone scalariform, on its taper, have several notches, its inwall has teeth patterning or does not have teeth patterning, main body (1) inwall is cylinder circular cone scalariform, on its termination outer wall, be provided with screw thread, this termination inwall port is the outer cone shape, gland (2) inwall is cylinder circular cone scalariform, be provided with screw thread at the one end head inwall, another termination inwall is cone shape, is disposed with heart retainer (3) between main body (1) and gland (2) inwall, seal ring (4), be provided with rectangular seal (6) in main body (1) inwall.
