Novel tubing nipple

Abstract

The invention provides a novel tubing nipple. The novel tubing nipple comprises a pipeline body and two groups of first flanges, wherein the two groups of first flanges are symmetrically welded to both ends of the pipeline body; a catalyzing pipe is arranged in the pipeline body in a transverse direction, the catalyzing pipe is composed of equal-diameter straight pipes and a corrugated pipe, bothends of the corrugated pipe and the equal-diameter straight pipe communicate with each other and are integrally formed, and the two groups of equal-diameter straight pipes are respectively welded to the first flanges; and a connecting piece is hinged to the outer sides of the first flanges, the connecting piece comprises a second flange and two groups of fixed parts, and the first flanges and thesecond flange are fastened and connected by virtue of the two groups of fixed parts. According to the novel tubing nipple, while fuel is catalyzed, the tight connection between the flanges is guaranteed, so that the sealing performance is improved, the fuel leakage probability is effectively reduced, finally, the service life is effectively prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of oil pipes, in particular to a novel short joint of oil pipes. Background technique [0002] The effective part of fuel engine heat work is about 35%, and most of it is lost through heat dissipation and smoke exhaust. The emission pollution of the engine mainly comes from the combustion exhaust gas discharged from the engine (accounting for more than 55%) crankcase blow-by gas (about Accounting for 10%), in which residual fuel incomplete combustion (accounting for about 10-25%). [0003] The existing fuel oil connection pipeline has the following problems: [0004] 1. Insufficient combustion of fuel oil leads to low energy utilization rate, produces a large amount of exhaust gas, and eventually pollutes the environment; [0005] 2. There will be dirt deposits on the fuel pipeline after long-term use; [0006] 3. The traditional pipeline connection is only connected by bolts, which has insufficient sealing perform...
