Abstract
The utility model provides a reinforced composite plastic pipe joint for metal frameworks, which comprises a pipe joint body. The inner side of the pipe joint body is provided with a metal framework which is compounded with the pipe joint body, has a similar shape with the pipe joint body, is covered by plastics, and is distributed with eyelets. The utility model is characterized in that an interface of the pipe joint body is provided with a conical inner cavity; the surface of the conical inner cavity is provided with a resistance wire heater; a positive terminal and a negative terminal are fixed to the same end of the pipe joint body, are led out in an axial mode or a radial mode, and is connected with a resistance wire. The utility model has the advantages of small manufacturing difficulty and long service life.
Description
The utility model relates to a kind of pipe joint, particularly be a kind of metallic skeleton reinforced composite plastic pipe joint.
Existing multiunit tube joint main body is to adopt cylindrical cavity, has on its metal frame inserts to guarantee that itself and body are in the locating pin of correct relative position mutually.The main body of this multiunit tube joint is to adopt cylindrical cavity, and its technology gap is determined that by ovality tolerance and diameter tolerance manufacture difficulty is big when being connected with pipe fitting, and the gap uniformity is difficult to guarantee, causes its join strength influenced.Because locating pin is exposed outside, corrosion and corrosion often are deep into metal frame from here at last in actual the use, make the pipe joint lost of life, cause whole joint strength to lose efficacy, and cause the seepage break accident.Heating element positive and negative electrode wiring terminal in the multiunit tube joint body that has is at the union body two ends, easily left over copper cash behind pipe fitting and the tubing electrothermal melting, may easily be produced micropore by deep-etching at the inner tube wall copper cash that contacts with fluid, run through the position that electric heating wire distributes, produce and leak and the shortening pipeline life., pipe fitting is made difficulty, reject rate height.
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, a kind of manufacture difficulty that reduces to be provided, the metallic skeleton reinforced composite plastic pipe joint of long service life.
The purpose of this utility model is achieved like this:
The utility model metallic skeleton reinforced composite plastic pipe joint comprises union body, have compound with it in the union body and shape is similar by the metal frame that is covered with eyelet of plastic overmold, it is characterized in that the union body jointing has conical cavity, resistance heater is equipped with on the conical cavity surface, just, negative terminal is fixed on the same end of union body, draw with resistance wire with axial or radial manner and to be connected (referring to Fig. 1～Fig. 7), will be just, negative terminal is fixed on the same end of union body, the inner tube wall that contacts with fluid is not left over copper cash, improve the antiseptic power and the life-span of pipeline, reduced the pipe fitting manufacture difficulty, reduced reject rate.
Above-mentioned metal frame adopts metal perforated plate to be welded.
Above-mentioned metal frame adopts the smart casting of metal to make.
Reinforcement convex tendon (referring to Fig. 7) is arranged on the above-mentioned metal frame.
Joint socket is arranged on the above-mentioned union body, and (referring to Fig. 2～Fig. 4), coincideing with internal diameter of the pipeline reduces resistance, helps the conveying of powdery, particle media.
The reinforcement convex tendon (referring to Fig. 4, Fig. 7) that ring-type and/or arcuation are arranged on the above-mentioned union body periphery.
Reinforcement convex tendon sectional shape on the above-mentioned union body periphery is a rectangle.
Reinforcement convex tendon sectional shape on the above-mentioned union body periphery is trapezoidal.
Reinforcement convex tendon sectional shape on the above-mentioned union body periphery is a triangle.
Reinforcement convex tendon sectional shape on the above-mentioned union body periphery is a circular arc, also can be other shape.
When using the utility model, because pipe joint jointing inner chamber is tapered, pipe fitting and joint fit tightly, so hot melt is even, and pipe fitting and pipe joint can axially be passed mutually in reflow process, further eliminate matching gap, the formation integrated type connects, in bond zone voidlessness, loose situation.In order to adapt to different installation requirements, that pipe joint can be made is two logical, threeway or many logical forms, and the angle between the interface can change between 0～180 °, the pipe joint diameter can be isometrical, also can make diameter reducing type, has the joint socket shape.
The utility model manufacture difficulty is less, long service life.
