And an arc corner is arranged between the second flanging and the arc metal pipe section. This kind of structural design can be in the same place the better complex of plastic joint body and metal insert, prevents to rotate, even the great screw power that metal insert received also prevents the displacement because of the limiting displacement of circular arc metal pipe section, avoids the weeping.
The inner diameter of the horizontal metal straight pipe section is smaller than that of the horizontal plastic straight pipe section. The end surface of the outer end part of the horizontal metal straight pipe section is a welding limiting end surface. The outer tip of horizontal metal straight tube section is equipped with outside turn-ups, and the turn-ups imbeds in the horizontal plastics straight tube section pipe wall, with the better complex of inserts and plastic connector body together, the spacing terminal surface of this kind of butt fusion simultaneously can avoid horizontal plastics straight tube section excessive butt fusion problem in the hot melt butt fusion in-process.
The outer end part of the vertical metal pipe section is provided with an outward first flanging, the first flanging is embedded into the pipe wall of the vertical plastic straight pipe section, the contact area is increased through the flanging structure in the structural design, and the insert and the plastic joint body are combined together better. And, the inside surface of vertical metal pipe section is equipped with the screw thread, and the screw thread design can conveniently be connected.
The plastic connector body comprises a horizontal plastic straight pipe section and a vertical plastic straight pipe section, and the horizontal plastic straight pipe section and the vertical plastic straight pipe section are integrally formed through injection molding of arc plastic pipe sections. The end part of the horizontal metal straight pipe section is positioned at the inner side of the end part of the horizontal plastic straight pipe section, and plays a role in internal limiting. The end part of the vertical metal pipe section is flush with the end part of the vertical plastic straight pipe section, and the plastic joint body and the metal insert can be better compounded by the structural design, so that the installation is convenient.
The plastic joint body is a PE plastic joint body
The beneficial effects of this practicality are as follows:
this practical structure can compound metal insert and plastic joint body together effectively, prevents metal insert's rotation and not hard up phenomenon through the metal insert who takes the elbow, strengthens the pipeline interface, connects the durability and plays the effect of leak protection liquid.
Drawings
FIG. 1 is a schematic view of the overall structure of a liquid leakage prevention joint with an elbow insert;
FIG. 2 is a cross-sectional view of a leak-proof fitting with an elbow insert;
Detailed Description
The liquid leakage preventing joint with the elbow insert shown in fig. 1-2 comprises a metal insert 2 and a plastic joint body 1 which are mutually injection-molded and compounded.
The external plastic joint body 1 comprises a horizontal plastic straight pipe section 10 and a vertical plastic straight pipe section, and the horizontal plastic straight pipe section 10 and the vertical plastic straight pipe section are integrally formed through injection molding of arc plastic pipe sections.
The metal insert 2 comprises a horizontal metal straight pipe section 7 and a vertical metal pipe section 9, and the horizontal metal straight pipe section 7 and the vertical metal pipe section 9 are integrally cast and molded through the arc metal pipe section 4. The metal is generally brass, the ductility of the brass is utilized to improve the compound force between the brass and the plastic, and the technical problems of rusting and the like of other metals are avoided. The end part of the vertical metal pipe section is flush with the end part of the vertical plastic straight pipe section, and the plastic joint body and the metal insert can be better compounded through the structural design.
The inner side of the cross section of the arc metal pipe section 4 is of a right-angle structure 3, and the outer side of the cross section of the arc metal pipe section is of an arc structure. The right angle structure both sides that fig. 2 shows are equipped with second turn-ups 5 and third turn-ups 6 respectively, and vertical plastics straight tube section is embedded to second turn-ups 5, and the horizontal plastics straight tube section of third turn-ups 6 embedding forms the clamping-force that has the right angle contained angle structure, increases the combined force between metal insert and the plastic joint body 1, relative and traditional linear structure's metal insert, the utility model discloses a fine solution of circular arc metal pipeline section structure the rotation clearance problem of leaking in the connection.
