Novel water heating pipe fitting

Abstract

The invention provides novel water heating pipe fitting, which comprises a heat preservation layer and a protective plate. The protective plate is made of color plates and wraps the outer side of the heat preservation layer, the protective plate is wrapped by a plastic pipe body layer, an internal thread is arranged at the inner portion of the heat preservation layer, and a plastic thread layer covers the two ends of the internal thread. The plastic thread closely fits the internal thread, and the plastic thread and the pipe body are identical in material and are connected to form a whole. According to the novel water heating pipe fitting, metal and plastic are combined, the advantages of the metal and the plastic are combined, a thread seal tape can be removed in mounting and using processes, and thereby the novel water heating pipe fitting is good in sealing performance, large in bearing capacity, and capable of being applied to complex environment. In addition, the color plates are used as the protective plate, so that the cost is saved, and the intensity and the corrosion resistance of the water heating pipe fitting are improved.

Description

technical field [0001] The invention relates to a novel plumbing pipe fitting. Background technique [0002] Existing plumbing pipe fittings are generally divided into two types: one is made of metal, and the other is made of plastic. The former has a greater bearing capacity and can be used in harsh environments, but the sealing is not good, and raw tape is needed to ensure it when used. Airtightness: the latter has better airtightness and can be used without raw tape, but its bearing capacity is weak, and it is easy to age, damage and leak when used in harsh environments. These two kinds of plumbing pipe fittings all have certain defects, are difficult to apply in complicated occasions, and are unfavorable for the popularization of products. Contents of the invention [0003] The invention provides a novel plumbing pipe fitting, which has good airtightness and thermal insulation, high bearing capacity and can be applied in complex environments. [0004] The technical s...
