Abstract
The utility model discloses a pipe connecting piece for plastic-lined steel tube. The drift diameter of the pipe connecting piece equals to the internal diameter of the plastic-lined steel tube. The utility model is characterized in that: protrusive reinforcing ribs which cross transversely and longitudinally are uniformly arranged on the outer surface of the connecting piece; an enameled coating is arranged on the inner surface of the connecting piece; a protective coating is arranged on the outer surface and the protective coating can be plastic-dipped coating or enameled coating. An annular groove is arranged at the root of the joint of the connecting piece and a rubber sealing ring which matches with the annular groove is arranged in the groove. The connecting piece overcomes the defects of the existing pipe fittings, such as the big loss in drift diameter, poor measures on guaranteeing the water quality, incredible adhesion of the corrosion-resistant coating on the outer wall, heavy weight, poor economic potential and so on; furthermore, the utility model is characterized by high intensity, reasonable structure, easy installation and so on.
Description
Technical field
The utility model relates to a kind of building, industrial line plastic-steel tube pipeline connecting parts.
Background technique
At present, line plastic-steel tube is used as novel pipeline and is popularized at China's building, industrial trade, but matching used with it lining plastic pipe is because can't be effectively bonding between plastic lining and the steel billet, the interlayer gap provides good living space for bacterium, microorganism, filth, thereby has the shortcoming that health concerns is big, the latus rectum loss is big; Usually at outer surface of pipe fittings hot galvanizing is arranged, soak mould, three kinds of modes of baking vanish carry out surface protection, but since long-term in the outside atmosphere environment since the zinc layer can oxidation totally, the coefficient of thermal expansion and contraction of nonmetal protection material and pipe fitting iron-based inconsistently occurs chapping, spalling phenomenon, thereby antiseptic power is not strong.Owing to interior pressure request and casting technique requirement, the wall thickness of existing pipe fitting is attenuate again, has the problem that weight lays particular stress on simultaneously, so need to improve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of line plastic-steel tube pipeline connecting parts, this link overcomes insecure reliable, the Heavy Weight of existing pipe fitting latus rectum loss measure imperfection, outer wall anti-corrosion layer big, that inwall guarantees the hygienic quality performance, the little shortcoming of Economy potentiality, and has intensity height, characteristics such as rational in infrastructure and easy for installation.
The problems referred to above of the present utility model are to solve like this: a kind of line plastic-steel tube pipeline connecting parts is provided, and latus rectum is consistent with the line plastic-steel tube internal diameter, it is characterized in that:
(1), the outer surface of described link is provided with evenly staggered in length and breadth protruding reinforcing rib;
(2), the internal surface of described link is provided with enamel layer, outer surface is provided with the outer surface protective coating.
According to line plastic-steel tube pipeline connecting parts provided by the utility model, it is characterized in that described outer surface protective coating can be to soak to mould layer or enamel layer.
According to line plastic-steel tube pipeline connecting parts provided by the utility model, it is characterized in that the root of the joint area of link is provided with circular groove, be provided with the rubber seal suitable in the groove with circular groove.
The line plastic-steel tube pipeline connecting parts that the utility model is carried, because the effect of stiffening rib increases pipe fitting intensity, thereby suitably attenuation of wall thickness, thereby alleviate the weight of pipe fitting, improve its economic performance, simultaneously because the effect of cutting apart of stiffening rib outer surface, make nonmetal protective coating be divided into several small sizes, and each fritter protection material has metal edge frame, this has just increased the adhesion of nonmetallic material and metallic material greatly, both have been solved because the inconsistent problems of bringing of linear expansion coeffcient make the outside surface anticorrosion erosion ability of pipe fitting strengthen.The sanitary enamel of internal surface because enamel coating surface hardness height, smooth, do not degrade, do not decompose, stable chemical performance, porcelain engage with metal melting, makes reliable, the water-fast stream of pipe fitting inner wall health wash away.The design of pipe fitting latus rectum is consistent with the line plastic-steel tube internal diameter, guarantees that pipe fitting does not have the latus rectum loss.The rubber seal of pipe fitting joint root guarantees that tube end face and irony position do not contact with the institute transporting fluid.
This link has not only guaranteed to carry the hygienic environment-protecting of water quality, and increases Economy in outer surface of pipe fittings creative utilization reinforcing rib design, has reduced cost of production, has increased anti-corrosion capability, has improved the working life of product.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 generalized section.
Wherein: 1, stiffening rib, 2, the internal surface enamel layer, 3, rubber seal, 4, the outer surface protective coating, 5, pipe thread, 6, the malleable cast iron blank.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As Fig. 1; Fig. 2 shows; this link latus rectum is consistent with the line plastic-steel tube internal diameter; outer surface is provided with evenly staggered in length and breadth protruding reinforcing rib 1; internal surface is provided with enamel layer 2; outer surface is provided with outer surface protective coating 4; outer surface protective coating 4 can be to soak to mould layer or enamel layer; the root of joint area is provided with circular groove; be provided with the rubber seal 3 suitable in the groove with circular groove; malleable cast iron blank 6 adopts the sand casting process casting to form; whole tube wall thickness is 2.5～3.5mm; the placement flute profile cast form of rubber seal 3, blank is through sandblast; shaping; the cleaning back processes pipe thread 5 with machine-tooled method, with binding tape protective tube screw thread 5 positions; inner and outer surface drops down the porcelain slurry, sends into quick roasting formation internal surface enamel layer 2 and outer surface protection enamel layer 4 in the enameling furnace after drying.
