For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simply rational in infrastructure, and pipe docking is stable, and sealing is strong, 90 ° of pipe joints that structural strength is large.
For achieving the above object, the utility model provides following technological scheme:
A kind of 90 ° of pipe joints, it is characterized in that: comprise the first end-to-end joint and second end-to-end joint connected vertically with the first end-to-end joint, first end-to-end joint comprises interconnective urceolus section and inner core section, inner core section comprises interconnective spacing section and construction section, the diameter of spacing section is greater than the diameter of construction section, construction section comprises the first thread section and restraining groove that connect for nut thread, slidably connect pad and "O"-ring in restraining groove, the outer wall of urceolus section is provided with screw thread;
Described second end-to-end joint comprises interconnective main body and external connection body, the diameter of main body is greater than the diameter of external connection body, external connection body comprises interconnective positioning section and seal section, positioning section comprises interconnective base segment and the second thread section, seal section comprises interconnective straight section and oblique section, the cross section of oblique section takes the form of inclined plane, and is configured with seal angle between oblique section and straight section, and the angle of seal angle is 40 °-50 °.
By adopting technique scheme, first end-to-end joint is with pipe docking operation, first be inserted in urceolus section to be threaded with urceolus section, again by being rotated in the nut on the first thread section, pad and "O"-ring is promoted by nut, "O"-ring is contacted with pipe, and pad prevents "O"-ring stress deformation and affects sealing effect.The sealing of the first end-to-end joint with pipe is substantially increased by the setting of pad and "O"-ring.Spacing section in inner core section arranges for the nut on the first thread section, plays the effect of stop nut, and is greater than the diameter of construction section due to the diameter of spacing section, spacing section of structural strength and the structure stability that can ensure that inner core section entirety.
The main body of the second end-to-end joint is the changeover part of water after two water pipe docking, therefore the diameter of main body is larger than the diameter of external connection body, ensures that main body is when by water extruding, structure remained stable.Positioning section on external connection body is used for connecting with pipe thread, and arranging of base segment can ensure that pipe is in the middle of the process be flexibly connected with the second thread section screw thread, the structure remained stable of positioning section.Seal angle can prevent the effect of the water spilling of docking in rear water pipe, particularly when the angle of seal angle is 40 °-50 °, best to the ability of the limit effect of water and the anti-current scour of seal section.
The utility model is arranged further: described first end-to-end joint is connected by shock reducing structure with the second end-to-end joint, and the two ends of shock reducing structure are connected with main body and spacing section respectively.
By adopting technique scheme, the setting of shock reducing structure substantially increases join strength and connective stability that the first end-to-end joint follows the second end-to-end joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, embodiment of the present utility model is described further.
A kind of 90 ° of pipe joints, comprise the first end-to-end joint 1 and second end-to-end joint 2 connected vertically with the first end-to-end joint 1, first end-to-end joint 1 comprises interconnective urceolus section 1b and inner core section 1a, inner core section 1a comprises interconnective spacing section 11 and construction section 12, the diameter of spacing section 11 is greater than the diameter of construction section 12, construction section 12 comprises the first thread section 121 and restraining groove 122 that are threaded for nut 5, slidably connect pad 3 and "O"-ring 4 in restraining groove 122, the outer wall of urceolus section 1b is provided with screw thread;
Described second end-to-end joint 2 comprises interconnective main body 2a and external connection body 2b, the diameter of main body 2a is greater than the diameter of external connection body 2b, external connection body 2b comprises interconnective positioning section 21 and seal section 22, positioning section 21 comprises interconnective base segment 211 and the second thread section 212, seal section 22 comprises interconnective straight section 221 and oblique section 222, the cross section of oblique section 222 takes the form of inclined plane, and is configured with seal angle between oblique section 222 and straight section 221, and the angle of seal angle is 40 °-50 °.
By adopting technique scheme, first end-to-end joint 1 is with pipe docking operation, first be inserted in urceolus section 1b to be threaded with urceolus section 1b, again by being rotated in the nut on the first thread section 121, pad 3 and "O"-ring 4 is promoted by nut, "O"-ring 4 is contacted with pipe, and pad 3 prevents "O"-ring 4 stress deformation and affects sealing effect.The sealing of the first end-to-end joint 1 with pipe is substantially increased by pad 3 and the setting of "O"-ring 4.Spacing section 11 on inner core section 1a is arranged for the nut on the first thread section 121, play the effect of stop nut, and be greater than the diameter of construction section 12 due to the diameter of spacing section 11, structural strength and the structure stability that can ensure that inner core section 1a entirety for spacing section 11.
