Abstract

The utility model relates to a cutting sleeve type pipeline joint, wherein a joint body and a screw cap are connected in a screw thread type; a sealing ring and a cutting sleeve ring are arranged inside the joint body and the screw cap; the ends of the inner head face of the joint body, the inner bottom of the screw cap and the cutting sleeve ring which contact the inner bottom of the screw cap are all provided with an inclined plane; the end of the cutting sleeve ring near the inclined plane is opened with a guiding deformation groove, while the other end contacts the sealing ring. The joint has a simple structure and good sealing performance and does not need professional installation.

Description

FERRULETYPE pipeline joint
The utility model belongs to pipe joint or pipe fitting technical field, is specifically related to the FERRULETYPE pipeline joint that a kind of metallic conduit connects usefulness.
In pipeline connection technology, the link good sealing property is a matter of utmost importance, secondly is the convenience that connects.Chinese patent ZL99239507 discloses " a kind of elastic ferrule formula pipe joint ", is made up of fittings body, nut and seal ring, establishes an inclined-plane near the seal ring place in the fittings body, also adorns an open card lasso and 1-2 seal ring in fittings body.This structure has and connects sealing preferably, and installing/dismounting is also more convenient.But this structure still has the following disadvantages: the one, increased a plain washer, and it is complicated that structure shows slightly, easily gets wrong during installation.The 2nd, the cutting ferrule circle is a broken ring, and the size of opening is difficult for grasping, if opening is established little, not tight during the interlock metal tube, if opening has been established greatly, when the interlock metal tube, can form wrinkle Zhe at the not closed place of opening, cause the metal tube distortion inhomogeneous, interlock influences sealing built on the sand.
The deficiency that the utility model exists at said structure, purpose is to provide a kind of structure simpler, and sealability is good, the FERRULETYPE pipeline joint that does not need specialty to install.
Structure of the present utility model is as follows:
FERRULETYPE pipeline joint, be connected by engage thread with nut by fittings body, establish seal ring and cutting ferrule circle in fittings body and the nut, fittings body interior edge face, nut inner bottom part and the cutting ferrule circle end that contacts with the nut inner bottom part is equipped with the inclined-plane, the cutting ferrule circle has guiding distortion groove by beveled end, and the other end contacts with seal ring.
Described inclined-plane is 30 ° of inclined-planes, and seal ring is taper or O shape O-ring seal.
The difference that the utility model and prior art are outstanding is to have designed a collar cover, and an end face of cutting ferrule circle is designed to the inclined-plane, and have guiding distortion groove near the inclined-plane, one of its effect is for compressing seal ring, two be under external force the plasticity by guiding distortion groove to internal strain, make metal tube evenly be compressed distortion, the locking metal tube.Adopt this cutting ferrule circle, a plurality of parts in the alternative existing structure, structure is simpler, and the particular design of this cutting ferrule circle, this link is only needed with less strength when mounted, and install easily, can not need the professional workforce to install.
Below in conjunction with drawings and Examples the utility model is described:
Fig. 1 is the structural drawing of the utility model when not connecting locking;
Fig. 2 is the structural drawing of the utility model after connecting locking;
Fig. 3 is a cutting ferrule circle parts drawing.
Embodiment: referring to Fig. 1,2 and 3, this FERRULETYPE pipeline joint is made of fittings body 1, nut 3, O-ring seals 2 and metal card lasso 5, and fittings body 1 interior edge face, nut 3 inner bottom parts and metal card lasso 5 end that contacts with nut 3 inner bottom parts is equipped with 30 ° of inclined-planes.Fittings body 1 is provided with outside thread, and nut 3 is provided with internal thread, and both can spin when connecting.Metal card lasso 5 has guiding distortion groove 6 by beveled end, and the other end contacts with O-ring seals 2.
During connection, nut 3, metal card snare 5 and O-ring seals 2 are imported metal tube 4 one ends that desire connects successively, then metal tube 4 is inserted in the fittings body 1, tightening nuts 3, make the outside thread engagement of the internal thread and the fittings body 1 of nut 3, nut 3 promotes metal card lasso 5 and O-ring seals 2, makes compression seal between fittings body 1 interior inclined-plane and metal tube 4 and O-ring seals 2 threes.Referring to Fig. 2, when metal card lasso 5 can not move inward again, the inclined-plane of metal card lasso 5 one ends is out of shape groove 6 place's plasticity to internal strain in guiding under the effect of external force, make the metal card lasso 5 inclined-planes metal tube 4 of nipping like this, and make metal tube 4 micro-strains, change as can be seen by the inclined-plane of metal card lasso 5 among the figure.Like this, metal card lasso 5 locking metal tubes 4 just can be finished the work that is tightly connected of metal tube 4 and fittings body 1
