Abstract
The utility model relates to an industrial overpressure resistant polypropylene pipe fitting, comprising a pipe with flanges on two ends. The flange is integrated with the pipe; the entire end face of the flange is a plane; several circles of cannelures, which are concentric with the central axis of the pipe, are arranged on the flange. An integrative flange is arranged on the pipe of the industrial overpressure resistant polypropylene pipe fitting, so the industrial overpressure resistant polypropylene pipe fitting has the advantages of reasonable structure, complete non-seam, high pressure resistance and convenient connection and disassembly via the flange. The contact area of the sealed plane of the end face of the flange is large, the seal ring cannot move via the cannelure, and the seal is reliable even when the line pressure is high.
Description
Technical field: the utility model relates to a kind of industrial pipe, particularly polypropylene pipe fitting.
Background technique: the pipe fitting that uses in industrial fields such as chemical industry, pharmacy, oil can adopt engineering plastics pipe corrosion protections such as polypropylene through being usually used in carrying the deep-etching pressured fluid.General polypropylene tube adopts end grafting heat seal to connect, and trouble is installed, and can't dismantle.Some flanged dish in polypropylene tube end, connect convenient disassembly, but flange plate and body adopt heat seal, seam is arranged easily, can not carry the liquid of higher pressure, and adopt boss subsides seal ring to seal between the flange plate end face, contact position aligns trouble, sealing contact surface is long-pending little, and reliability is not enough when higher pipeline pressure.
Summary of the invention: at the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, the industrial withstand voltage polypropylene pipe fitting that resistance to pressure is higher.
The utility model comprises that two ends are provided with the body of flange plate, and flange plate and body are the integral molding structure, and the end face of flange plate is whole to be a plane, is provided with multi-turn and the concentric stria of body central shaft above.
Body of the present utility model is provided with the flange plate of integral type, rational in infrastructure, there is not seam fully, the resistance to pressure height, it is all more convenient to connect dismounting by flange plate, and the end face seal plane contact area of flange plate is big, by stria seal ring is fitted and is not shifted, and sealing is also very reliable when higher pipeline pressure.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is another form figure of embodiment.
Specific embodiment: as depicted in figs. 1 and 2, the two ends of body 1 are provided with flange plate 2, and flange plate 2 and body 1 are the integral molding structure, and the end face of flange plate 2 is whole to be a plane, are provided with the concentric stria 3 of multi-turn and body 1 central shaft above.Stria 3 is generally established two circles can make seal ring reliably fit, and the end face Butt sealing of flange plate 2 is very high.Embodiment can be made into various forms, is illustrated in figure 3 as bend pipe.Present embodiment adopts the Reinforced Polypropylene made, and is rational in infrastructure, easy accessibility, and the resistance to pressure height, and also contractibility is little, and corrosion-resistant, the intensity height, smooth surface is attractive in appearance.
