Abstract
The present invention relates to a novel self tightening fast pipe joint which comprises a female joint, an O-shaped sealing ring and two male joints, wherein a self tightening pressure groove and a sealing groove are respectively arranged on the two male joints; cross section shapes of engaging teeth of excircles of the ends of the male joints (A), (B) and the inner circles of the corresponding female joint are more than two projected circular arc surfaces in equal division; when the female joint rotates, the present invention has axial displacement, and the O-shaped sealing ring can be tightly pressed on the side surface of the self tightening pressure groove. The present invention can replace various kinds of flange connection, and has the advantages of self tightening sealing function, fast assembly and disassembly, material saving, compact structure, small size and wide application range. Thus, the present invention has important generalization and application value on various industrial pipelines.
Description
The present invention relates to device, a kind of novel self-locking quick pipe connector that compresses seal ring with axial moving piece with pipe box and base connecting pipeline.
Connect between container, pipeline and the valve there to be modal connecting mode: flange connects and the screw thread connection; Existing these two kinds of connecting modes respectively have its inherent defect, connect mounting or dismounting inconvenience as flange, and consumptive material is many and cost is higher; It is not too reliable that screw thread connects sealing, can only be used for the low pressure occasion; The connection of alternate manner connects with speed as lap joint flange, fire-fighting, and what have is bulky, the manufacturing complexity that has; And ubiquity does not have the drawback of self-tightening sealing function.
The objective of the invention is it provides a kind of manufacturing and extremely easy to use, and has the self-tightening sealing function, and the pipe joint that can connect fast can be used for connecting between pressurized container, pipeline and the valve safely and reliably.
In order to achieve the above object, technological scheme of the present invention is: it comprises the negative joint that has interior engaging tooth, O RunddichtringO, two male connectors that have the outer gearing tooth; Also be respectively equipped with self-tightening pressure tank and seal groove on the male connector; The engaging tooth section configuration of circle is the arc surface of 2 above five equilibriums and protrusion in the end cylindrical of male connector (A) and male connector (B) and the corresponding negative joint; The rotation negative joint produces axial displacement, the O RunddichtringO can be pressed on self-tightening pressure tank side.
Below in conjunction with accompanying drawing,, provide detail of the present invention by description to embodiment.
Fig. 1, connecting structure schematic diagram of the present invention;
The C-C sectional drawing of male connector (A) in Fig. 2, the accompanying drawing 1.
As depicted in figs. 1 and 2, the proximal end face inboard of male connector (A) 1 has self-tightening pressure tank 2, male connector (B) 6 end faces have seal groove 5, O RunddichtringO 4 is placed between seal groove 5 and the self-tightening pressure tank 2, it is the end face contact, axial displacement (the engaging tooth hand of spiral at negative joint two ends is opposite) by rotation negative joint 3 produces is pressed on self-tightening pressure tank side with O RunddichtringO 4, realizes self-tightening sealing.As shown in Figure 2, the interior engaging tooth section configuration that has a circle in the end cylindrical of male connector (A) 1 of outer gearing tooth and the corresponding negative joint is the arc surface of 2 above five equilibriums and protrusion; Rotation negative joint 3 is no more than 90 promptly detachable; Negative joint 3 can also fall back on the pipeline on one side of male connector (A) or male connector (B); On negative joint 3, can offer the mounting hole of mounting or dismounting usefulness in case of necessity and, increase stopping screw between male connector at the moon.
According to the pressure and temperature of medium, the O RunddichtringO can be selected unlike material for use; The hold-down ring of self-tightening pressure tank can adopt different thickness with caliber according to pressure; The material of yin, yang joint can be a metal or nonmetal.
The present invention compares the beneficial effect that has with background technology:
1, have the self-tightening sealing function, namely pressure medium is higher, and sealing is more reliable;
2, quickly assembled and disassembled, rotation is no more than 90 and can loads onto or pull down, and installs Very convenient with maintenance;
3, save material in a large number, compare with existing flange, the present invention can save the material more than 80%;
4, compact structure, volume is little, be convenient to stringing and insulation:
5, applied widely, can replace container, pipeline and valve that various flanges are used for various calibers, various pressure and medium.
In addition, the present invention also has the advantage of the standardization of being convenient to, seriation; Therefore, on various industrial pipelines, has great popularizing value.
Claims (4)
