Abstract
The utility model discloses a crimping pipe joint. The utility model is characterized in that one port of a joint body is provided with a tongue; two to three sealing rings and one elastic circlip are arranged in the tongue. When the utility model is used, only a crimper is needed during construction, the connection is convenient and quick, the connecting point between a pipe and the pipe joint is firm, and the sealing property is superior. After the pipe is connected with the pipe joint, the sealing effect can not be affected by shocking, shaking, drawing, pressing, etc. caused by external force. Proved by hydraulic test, the sealing pressure of the utility model can reach 5 MPa. The utility model can be widely used in construction for connecting water pipe joints and in industry for connecting the joints of oil pipes, gas pipes, water pipes, etc.
Description
Technical field:
The utility model relates to the technical field of pipe joint, specifically a kind of elastic circlip formula aluminium hydraulic pressed connecting pipe joint that can connect fast.
Background technique:
The quick aluminium hydraulic pressed connecting pipe joint of pipeline of the prior art mainly is made up of fittings body and the built-in seal ring of fittings body, and there are the following problems for such pipe joint:
1, tightness is not enough after pipe and the pipe joint crimping, is to utilize its one-sided or bilateral to have hexagonal distortion impression to play fastening effect;
2, because sealing is that rubber will wear out after having spent the regular hour by the seal with elastometic washer of single O shape, therefore the sealing effect to pipe fitting can descend;
3, this pipe joint can not bear higher pipe internal pressure.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved aluminium hydraulic pressed connecting pipe joint, and it can strengthen the soundness and the sealing effect of joint and pipe seam crossing.
The technical solution of the utility model is achieved in that a kind of aluminium hydraulic pressed connecting pipe joint, it mainly comprises fittings body and places the interior seal ring of fittings body, it is characterized in that: the port at fittings body has a tongue, is built-in with 2-3 seal ring and an elastic circlip at tongue.
The utility model is owing to establish a tongue at the port of fittings body, at built-in 2-3 seal ring and the elastic circlip of being placed with of tongue, when construction, only need a Press Plier, easy to connect rapid, pipeline is connected very firm with the pipe joint place, sealability is good, and pipeline is with after pipe joint is connected, the vibration of external force, shake draw, pressurization etc. all can not influence its sealing effect, can reach 5Mpa through its sealing load of hydraulic test.

Fig. 2 is another embodiment's of the utility model a structural representation
Fig. 3 is a user mode schematic representation of the present utility model
Fig. 4 is the A-A view of Fig. 3
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises fittings body 1 and places the interior seal ring of fittings body, it is different from prior art and is: the port at fittings body 1 has a tongue 5, this tongue is more roomy, be built-in with 2-3 seal ring and an elastic circlip 4 at tongue 5, have at least one to be nonmetal seal ring 2 in the seal ring of in tongue, placing in the enforcement, compare with elastic circlip and other seal ring, this nonmetal seal ring apart from the fittings body port farthest, other seal ring 3 can be metal o-ring, also can be nonmetal seal ring, the present embodiment tongue first half is approximate to be
Type, the section of nonmetal seal ring is approximate to be O shape, rectangular, trapezoidal, right-angled triangle or right-angled trapezium, and other well-regulated shape, and the mark 6 in the accompanying drawing is a pipeline.
This pipe joint need cut metallic conduit 6 by length earlier when mounted, directly insert the metallic conduit port that cuts in the fittings body again, adopt special-purpose Press Plier directly the interlock of exerting pressure of the more roomy tongue place of pipe joint to be got final product then, the section of metallic conduit and pipe joint interlock place all is hexagon or octagon distortion after the crimping, make pipeline and the joint elastic circlip 4 between it play the effect of fixing tube like this, in addition under the both sides or one-sided external force effect of the tongue of the pipe joint port after the crimping at Press Plier, make metallic conduit and pipe joint place all be hexagon or octagonal deform in same pace, thereby more increased the connectivity robustness of metallic conduit and pipe joint, feedwater piping joint during this pipe joint can be widely used in constructing and the oil in the industry, gas, the joint of pipelines such as water connects.
