Description
The utility model relates to a kind of pipe coupling, particularly a kind of clasp type pipe joint that is applicable to various fluid-transporting tubings.
Existing pipe joint generally is tapped sleeve pipe, its type is divided into single-pass joint, tee union and elbow, these pipe joints when mounted, after must will being processed into the screw thread that matches with the internal thread of pipe joint by adapter end, road outer wall with special tool, just can assemble, its mode of operation is numerous and diverse; After long-term the use, corrosion can take place in pipe joint, and it not only can pollute the water that is transferred, and influence health, and is subject to the extraneous factor influence and shakes, and causes pipe joint to become flexible and the phenomenon of seepage occurs, has wasted the fluid that is transferred.
The purpose of this utility model just provides a kind of simple installation, shock resistance is strong and the clasp type pipe joint of long service life.
The purpose of this utility model is to realize by such technological scheme, it includes union body, banding plug screw and seal ring, it is characterized in that: the through-hole wall at union body is disposed with internal thread from outside to inside, conical surface, ring-shaped step, banding plug screw outer wall is provided with the outside thread that matches with the union body internal thread, inwall at banding plug screw through hole one end is provided with conical surface, the snap ring outer wall of band opening is provided with external conical shape face that matches with the conical surface of union body and the external conical shape face that matches with the conical surface of banding plug screw, and the snap ring inwall is provided with the inner conical face.
During installation, with the banding plug screw, snap ring is enclosed within successively to be taken on the road, seal ring is placed ring-shaped step place in the union body through hole, the end that to be taken over the road is against in the seal ring in the union body through hole, snap ring is against on the seal ring, use common spanner with of the internal thread precession of banding plug screw then along union body, screw-in along with the banding plug screw, the acting in conjunction of the conical surface in the union body and the external conical shape face of the snap ring that matches with it, and the opening of snap ring makes it have elasticity, and what force snap ring is interior through dwindling, and inwardly compresses seal ring, simultaneously, because the effect of the inner conical face of snap ring produces perpendicular to the radial pressure of being taken over the road axis snap ring, will can not be come off by adapter road chucking, thereby make complete with extraneous the completely cutting off of the interior fluid of carrying of pipeline, reached leakage proof and the firm purpose of installation.The effect of ring-shaped step is stable by the adapter road, avoids rocking because of the external force influence.
Owing to adopted technique scheme, the utlity model has advantages such as simple in structure, convenient and flexible installation and long service life, do not need special tool, just can easily it be installed securely, and be difficult for corrosion and loosening, avoided being transferred the seepage of fluid.

Among the figure: 1. union body; 2. banding plug screw; 3. seal ring; 4. internal thread; 5. conical surface; 6. ring-shaped step; 7. outside thread; 8. conical surface; 9. snap ring; 10. external conical shape face; 11. external conical shape face; 12. inner conical face; 13. conical surface; 14. conical surface; 15. annular pointed tooth; 16. taken over the road; 17. annular table; 18. conical surface.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes union body 1, banding plug screw 2 and seal ring 3, it is characterized in that: as can be known in conjunction with Fig. 2, through-hole wall at union body 1 is disposed with internal thread 4 from outside to inside, conical surface 5, ring-shaped step 6, in conjunction with Fig. 3,4 as can be known, banding plug screw 2 outer walls are provided with the outside thread 7 that matches with union body 1 internal thread 4, inwall at banding plug screw 2 through holes one end is provided with conical surface 8, in conjunction with Fig. 5,6 as can be known, snap ring 9 outer walls of band opening are provided with external conical shape face 10 that matches with the conical surface 5 of union body 1 and the external conical shape face 11 that matches with the conical surface 8 of banding plug screw 2, and snap ring 9 inwalls are provided with inner conical face 12.
As shown in Figure 1, during installation, with banding plug screw 2, snap ring 9 is enclosed within successively to be taken on the road 16, seal ring 3 is placed ring-shaped step 6 places in union body 1 through hole, the end that to be taken over road 16 is against in the seal ring 3 in union body 1 through hole, snap ring 9 is against on the seal ring 3, use common spanner with internal thread 4 precessions of banding plug screw 2 then along union body 1, screw-in along with banding plug screw 2, the acting in conjunction of the conical surface 5 in the union body 1 and the external conical shape face 10 of the snap ring 9 that matches with it, and the opening of snap ring 9 makes it have elasticity, force the interior of snap ring 9 through dwindling, and inwardly compress seal ring 3, simultaneously, because the effect of the inner conical face 12 of snap ring 9, snap ring 9 is produced perpendicular to the radial pressure of being taken over road 16 axis, to and can not come off by adapter road 16 chuckings, thereby make complete and extraneous the completely cutting off of the interior fluid of carrying of pipeline, reach leakage proof and the firm purpose of installation.The effect of ring-shaped step 6 is stable by adapter road 16, avoids rocking because of the external force influence.
As shown in Figure 7, taken over for the ease of banding, the outer wall of seal ring 3 is provided with the conical surface 13 that matches with the inner conical face 12 of snap ring 9; The outer wall of seal ring 3 is provided with the conical surface 14 that matches with the conical surface 5 of union body 1.The conical surface that both direction is opposite produces two perpendicular to the radial pressures of being taken over road 16 axis under the mating reaction of the inner conical face 12 of the conical surface 5 of union body and snap ring like this, is taken over 16 effect to strengthen banding.Seal ring 3 is provided with annular table 17, and its effect is that the front end of being taken over road 16 is closely contacted with seal ring 3, prevent to be taken over 16 and union body 1 break away from because of hydraulic pressure is excessive.
Shown in Fig. 3,4, the outer wall of banding plug screw 2 is provided with six square toes or all directions head, so that with in the banding plug screw 2 spinning in pipe fittings bodies 1.
As shown in Figure 6, can be provided with the conical surface 18 that constitutes wedge shape with inner conical face 12 on the snap ring 9, the wedge shape that inner conical face 12 is formed with conical surface 18 snaps in like sharp sword is taken in the road, is taken over the road so that banding is fixing; Inwall that also can snap ring 9 is provided with annular pointed tooth 15, so that taken in 16 processes at banding, annular pointed tooth snaps in and taken on the road, plays the fixing effect of being taken over road 16 of further banding.
As shown in Figure 1, 2, the skin of union body 1 is a metal, and internal layer is plastics, with the fluid that guarantees to be transferred in the pipeline fully with the completely cutting off of metal, avoided corrosion, reduced pollution, prolonged working life of the present utility model.
