Abstract
The utility model discloses a joint assembly. The body of the joint assembly is a sleeve with a flange, and the outer diameter of the sleeve corresponds to the internal diameter of the pipe to be connected, an O-shaped rubber sealing ring is arranged between the sleeve and the pipe to be connected. The exterior of the body is sheathed with an open elastic cutting sleeve, the interior of the elastic cutting sleeve is provided with convex canine teeth. The internal diameter of the elastic cutting sleeve accommodates to the outer diameter of the pipe to be connected, and a conical surface is arranged on the exterior of the open elastic cutting sleeve and can be cooperated with the bevel of a joint flange. A bevel is arranged in the joint flange and corresponds to the conical surface of the open elastic cutting sleeve, and the joint flange is also provided with screws. The joint assembly can be used for jointing metal-plastic composite pipes of medium or large pipe diameters, the locking force and the strength both satisfy the operating requirements, and the joint assembly is reusable.
Description
The utility model relates to a kind of pipe coupling, in especially a kind of being suitable for, the composite metal-plastic pipes of the big caliber pipe fitting of plugging into.
At present, external advanced country and China all attach great importance to and use the water hygiene, what wherein have the greatest impact is the old-fashioned molten iron pipe of continuing to use, the most effective way is to adopt plastic tube or metallo-plastic new composite pipeline, because old-fashioned pipe fitting can not be applicable to novel pipeline, so, influence the popularization of novel pipeline always.
Existing more common pipe connector has two kinds, and a kind of is the mechanical type pipe connector, and another kind is the hot melten type pipe coupling.The mechanical type pipe connector promptly adopts the hexagon nut locking mode, and when the recanalization that uses at big external diameter, the hexagonal that seems cylindrical is very big, causes the operating range of construction bigger, and to the coupling mechanism force deficiency of pipeline, hexagon nut is more easily burst; When being used for the good composite metal-plastic pipes of rigidity, its coupling mechanism force and intensity just more can't be born.And the hot melten type pipe coupling, because that the type joint requires when plugging into pipeline at the scene is more loaded down with trivial details, equipment is bigger, and is unfavorable for changing water channel in the future, hinders the installation and the development of whole pipe network greatly, when requiring use composite metal-plastic pipes, just more can't use.
The purpose of this utility model provides a kind of adapter assembly, and during it is applied to, the composite metal-plastic pipes of big caliber plugs into, coupling mechanism force and intensity all can satisfy usage requirement, and can use repeatedly.
The purpose of this utility model is achieved in that a kind of adapter assembly, comprises body, and body is a flanged sleeve, and the external diameter of sleeve is corresponding with the internal diameter of the pipeline of waiting to plug into, and is provided with O shape rubber seal between the two; The outside of body is with the opening elastic ferrule, and the inside of opening elastic ferrule is provided with the canine tooth of protrusion, and the external diameter of its internal diameter and the pipeline of waiting to plug into adapts, and the outside of opening elastic ferrule is provided with the conical surface that can cooperate with the inclined-plane of joint flange; Joint flange inside is provided with and the corresponding inclined-plane of the opening elastic ferrule conical surface, and is provided with screw, is with bolt in it.
The opening of opening elastic ferrule is oblique setting.
One end of body is provided with flange.
The middle part of body is provided with flange.
The middle part of body is provided with flange, and an end is provided with the interface that is connected with common metal pipe or valve.
Joint body one end links to each other with pipeline to be plugged into, and the other end is provided with standard pipe thread.
The utility model is because body is a flanged sleeve, and the external diameter of sleeve is corresponding with the internal diameter of the pipeline of waiting to plug into, and is provided with O shape rubber seal between the two; The outside of body is with the opening elastic ferrule, and the inside of opening elastic ferrule is provided with the canine tooth of protrusion, and the external diameter of its internal diameter and the pipeline of waiting to plug into adapts, and the outside of opening elastic ferrule is provided with the conical surface that can cooperate with the inclined-plane of joint flange; Joint flange inside is provided with and the corresponding inclined-plane of the opening elastic ferrule conical surface, and is provided with screw, is with bolt in it, thus it can be applicable in, the composite metal-plastic pipes of big caliber plugs into, coupling mechanism force and intensity all can satisfy usage requirement, and can use repeatedly.
Below in conjunction with concrete structure and the working principle of accompanying drawing detailed description according to the adapter assembly that the utility model proposes.

Figure 11 is the D place enlarged view of Figure 10.
As shown in Figure 1, 2, adapter assembly of the present utility model comprises: opening elastic ferrule 1, body 2, bolt 3 and joint flange 4.
Be with opening elastic ferrule 1 in the outside of body 2, adopt the high manganese steel bar, by forging, lathe grinding, milling machine cut-off mouthful and quenching heat treatment hardness at HRC45-48.The inside of opening elastic ferrule 1 is provided with the canine tooth of protrusion, and the external diameter of its internal diameter and the pipeline of waiting to plug into adapts, and the outside of cutting ferrule 1 is provided with the conical surface, cooperates with the inclined-plane of joint flange 4; As Fig. 3,4,5, the opening on it is oblique setting.
During use, the pipeline 5 of will waiting respectively to plug into inserts that this is external, in the opening elastic ferrule, flange with two bodies docks then, bolt is penetrated in the screw of two joint flanges, joint flange presses because of bolt, and it is moved axially again, and then make the opening elastic ferrule under the effect of the conical surface, produce radial deformation, the cusp outer diameter tube to be plugged into of nipping, the time adapter assembly locking pipe fitting, unlikely getting loose.
In addition, shown in Fig. 6,7, joint body 2 also is provided with the sleeve 6 of flange at the middle part, and other part as hereinbefore.
Moreover, shown in Fig. 8,9, joint body 2 also an end link to each other with pipeline to be plugged into, the other end is provided with standard pipe thread.
Moreover, shown in Figure 10,11, joint body 2 also an end link to each other with pipeline to be plugged into, the other end is connected with common metal pipe or valve 7.
