Abstract

The utility model discloses a pipe connector which comprises a connector body with inner screw and a connector with outer screw and connected to the inside the connector body. The utility model is characterized in that the connector and the connector body are made of plastic; the outer section and the inner section of the inner screw of the connector body are metal screw. Compared with the prior art, the utility model has a higher pressure resistance and also has the advantages of good corrosion resistance at the same time.

Description

A kind of pipe jointer
Technical field:
The utility model relates to a kind of connector, particularly the pipeline connector.
Background technique:
Existing pipe jointer mainly is made of fittings body, joint.This kind pipe jointer is no matter be fittings body or joint, and their material is full-metallic or is all-plastic.The joint, the fittings body that adopt full-metallic to make cooperate the suitable seal circle not reveal with regard to the very high pressure of ability, but because metal has relatively more active chemical property, if flow in the pipeline be the stronger fluid of corrosivity the time metalwork that contacts with fluid in (comprising liquid, gas) joint, the fittings body be corroded easily and produce harmful impurity, can destroy the connection usability of joint, fittings body in the time of seriously.The plastics of extensive chemical inertia can not corrode by being corroded property fluid though the joint, the fittings body that adopt all-plastic to make have very, because the poor rigidity of plastics, the combination force after joint, the fittings body combination is not enough, makes its withstand voltage properties poor.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of very high withstand voltage properties that both had, and has the pipe jointer of good decay resistance simultaneously again.
The utility model is to realize like this, comprise the fittings body that has internal thread, be threaded in the externally threaded joint that has in the fittings body, its specialization is that the material of joint, fittings body is plastics, outer section of the fittings body internal thread is metal threaded, and the externally threaded inner segment of joint is metal threaded.During work, by the inner segment with strong rigidity is that metal threaded joint outside thread and outer section are that the screw thread of metal threaded fittings body internal thread screws power and is screwed in joint in the fittings body securely, simultaneously, the screw thread that the screw thread that outer section is plastics on the joint and the interior inner segment of fittings body the are plastics distortion of combining closely, produce interference fit, the junction plane of joint and fittings body is tightly sealed, like this, both guaranteed that pipe jointer had higher withstand voltage properties, pulling capacity is up to 1000 Ns, simultaneously, plastic whorl be sealed and matched and to have prevented that corrosive fluid in the pipeline from penetrating into metal threaded internal corrosion metal threaded, the pollution of stopping the metal ion convection cell.
Here, metal threadedly can constitute by the thread section more than a section or a section.So both guarantee fastness and withstand voltage properties that joint combines with fittings body, saved the metal material simultaneously again.
For easy to manufacture, the metal threaded outside is provided with the metal lining ring, and the metal lining ring is embedded in the plastics on joint or the fittings body.The metal lining ring processes together with the metal threaded and joint on it, fittings body integral body.Because metal lining ring and joint, fittings body are linked to be integral body, like this, the metal threaded joint power that is delivered on joint, the fittings body is uniform, guarantee the uniformity of the interference fit of the screw thread that screw thread that outer section is plastics on the joint and the interior inner segment of fittings body are plastics, improved the sealability of the combination of plastic whorl.
For inner segment in screw thread that to make on the joint outer section be plastics and the fittings body is that the combining of screw thread of plastics has sufficient interference fit, the external thread section of joint is taper, and the fittings body internal thread segment also is the taper that matches with the joint outside thread.
For the metal lining ring is securely fixed in joint, the fittings body, can be provided with one or above how much grooves, hole on the metal lining ring, also can be provided with one or above tooth.Because metal lining ring and joint, fittings body integral body add man-hour plastics and are expelled in geometry groove, the hole, the metal lining ring is positioned in the joint, fittings body securely and variation on can occurrence positions, thereby the metal lining ring is securely fixed in joint, the fittings body.
For prevent to screw joint in fittings body the time metal lining ring skid along the joint axis, metal lining ring bore area is provided with groove along axial direction, like this, the formed spline of groove of metal lining ring endoporus just can make the metal lining ring be positioned in the joint securely.Metal threaded and plastic whorl on the joint is and is interrupted the embedding shape, like this, under the restriction of plastic whorl, has prevented that further the metal lining ring from skidding along the joint axis.
The utility model compared with the prior art, owing to adopted cooperating of metal threaded and plastic whorl, metal threaded firm combination force and plastic whorl good sealing property are organically combined, therefore, both had very high withstand voltage properties, had the advantage of good decay resistance simultaneously again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises the fittings body 1 that has internal thread, be threaded in the externally threaded joint 2 that has in the fittings body 1, its specialization is joint 2, the material of fittings body 1 is plastics, outer section 3 of fittings body 1 internal thread is metal threaded, inner segment 7 is plastics, joint 2 externally threaded inner segments 4 are metal threaded, outer section 8 is plastics, plastics section 7,8 screw threads can be circle screw threads, also can be two the circle screw threads or more than, metal threadedly can constitute by the thread section more than a section or a section, each section can be a circle screw thread for metal threaded section, also can be two circle screw threads, also can be three circles or the above screw thread of three circles, metal threaded 3,4 outsides are provided with metal lining ring 5,6, metal lining ring 5, in 6 plastics that are embedded on joint 2 or the fittings body 1, metal lining ring 5,6 together with the thread section on it 3,4 with joint 2 or fittings body 1 integral body process accordingly, it is cylindric that the external thread section of joint 2 can be, also can be taper, fittings body 1 internal thread segment also is the cylindric or taper that matches with joint 2 outside threads, metal lining ring 5, one or how much above recess holes 9 be can be provided with on 6, one or above tooth 10 also can be provided with.
As shown in Figure 2, metal lining ring 6 bore areas evenly are provided with groove 11 along axial direction, and metal threaded 4 on the joint 2 is with plastic whorl 8 and is interrupted the embedding shape.
