Abstract
The utility model provides a metallic composite pipe fitting used for conveying liquid medium. The utility model comprises a plastic pipe fitting. The metallic composite pipe fitting is characterized in that a metallic frame is arranged in a plastic pipe fitting wall and is compounded with the plastic pipe fitting. The shape of the metallic frame is similar to the shape of the plastic pipe fitting. The metallic frame is provided with tens or hundreds or thousands of small holes. The metallic composite pipe fitting has the advantages of good effect, corrosion resistance, high strength, good sealing performance, easy installation and adjustment, and long service life.
Description
The utility model relates to a kind of improved pipe fitting, particularly be a kind of metal composite pipe fitting that is used for the conveyance fluid medium.
The metal compounded pipe (pipe fitting) that is used for the hydraulic fluid conveying that has the sixth of the twelve Earthly Branches adopts at pipeline or pipe fitting end and is shaped on the domatic boss that flange connects usefulness in advance, need process the groove of dress seal ring on the end face, need seal ring, special steel flange during connection, tighten up and reach sealing purpose by bolt, nut.This mechanical seal is very inconvenient to the installation of big caliber and buried pipe, inefficiency, and being corrosive also as environment needs anticorrosionly or select expensive material for use to flange, bolt etc., and engineering cost increases.
In view of above reason, the purpose of this utility model is for a kind of anticorrosion, good seal performance is provided, and the high long service life of intensity is convenient to the metal composite pipe fitting of installing, connecting.
The purpose of this utility model is achieved in that plastic pipe in the utility model, it is characterized in that having in the plastic pipe wall metal frame compound to plastic pipe and that shape is similar to it, have tens of on the metal frame or imitate hundred or thousands of aperture (referring to Fig. 1～Fig. 6), the shape of aperture can be circular, also can be square, rhombus or other shape.
Above-mentioned metal frame adopts metal perforated plate to make (referring to Fig. 5, Fig. 6).
Above-mentioned metal frame can adopt wire gaze to make.
The metal frame that contains aperture that is composited that the utility model has adopted plastic pipe and has been placed in one, applicable to the big or little fluid of various difference variation, composite effect is good, corrosion-resistant, the intensity height, sealability is good, has cancelled domatic boss and has been convenient to the end face seal groove install, be connected, long service life, applied widely.In order to adapt to different installation requirements, that the utility model can be made is two logical, threeway, many logical joints; Angle between the interface can change between 0～180 °, and the diameter of pipe fitting can be isometrical, also can be reducing.The utility model pipe fitting can connect corrosivity such as being applied to oil, rock gas, chemistry with multiple tube stronger, the pressure flowing medium transportation art of having relatively high expectations.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is 90 ° of elbow structure schematic representation of the utility model.
Fig. 2 is the distribution schematic diagram one of aperture on metal frame.
Fig. 3 is the distribution schematic diagram two of aperture on metal frame.
Fig. 4 is two metal composite pipe fitting connection diagrams.
Fig. 5 is 135 ° of elbow structure schematic representation of the utility model.
Fig. 6 is the utility model right-angle tee structural representation.
Referring to Fig. 1, metal frame 2 die casting similar to it are combined into whole joint 3 to plastic pipe 1 with shape.Be distributed with hundreds of apertures 4 on the metal frame 2, the rectangular that the circle that the shape of aperture 4 can be as shown in Figure 2 also can be as shown in Figure 3.Its integral joint is 90 ° a elbow.
Referring to Fig. 4, when being connected, can adopt pipe joint 5 at two composite pipe fittings (or pipe fitting and pipeline).Joint for plastic tube body 6 is arranged in the pipe joint 5, be evenly distributed on that helical heater element 7, two wiring terminals 8,9 one ends in the joint for plastic tube body are connected on the heater element 7 and the other end and power supply (ac power supply or DC electrical source all can) be connected.In two composite pipe fitting insertion tube joints 5, connect power supply, the heater element heating makes connected metal composite pipe fitting outer wall plastics and pipe joint 5 inwall plastic moltings, and blending combines together after the cooling mutually, reaches the purpose that connects sealing.
Metal frame 2 can adopt metal perforated plate to make also can to adopt wire gaze to make.
135 ° of elbow structure forms that the metal composite pipe fitting can be made as shown in Figure 5 also can be made right-angle tee structural type or other structural type as shown in Figure 6.
Claims (3)
1, the metal composite pipe fitting comprises plastic pipe, and it is characterized in that has metal frame compound to plastic pipe and that shape is similar to it in the described plastic pipe wall, and tens of hundreds of or thousands of apertures are arranged on the metal frame.
2, metal composite pipe fitting according to claim 1 is characterized in that described metal frame can adopt metal perforated plate to make.
3, metal composite pipe fitting according to claim 1, it is characterized in that described metal frame can the fruit make with wire gaze.
