Abstract

The invention discloses a sealing leakage-proof device for an automobile fluid bend. Cylindrical sealing plates are arranged at the two ends of the bend. A cylindrical hollow connector is arranged at one end of the bend, and an outer thread is arranged on the hollow connector. The corresponding cylindrical sealing plate is located between the bend and the hollow connector. An inner thread is arranged at the other end of the bend, and the inner thread is located between the bend and the corresponding cylindrical sealing plate. A through hole is formed in the center of each cylindrical sealing plate, and the through holes communicate with the bend. Four insertion connecting holes are evenly formed in the periphery of each through hole, and threads are arranged on the inner walls of the insertion connecting holes. By means of the above manner, the problem that an automobile fuel bend in the prior art is prone to oil leakage is solved.

Description

technical field [0001] The invention relates to the field of pipe sealing, in particular to a sealing and leak-proof device for an automobile fluid elbow. Background technique [0002] There are many pipelines connected to each other in the gas power system of automobiles, and fuel liquids are transported in the pipelines, such as gasoline, diesel oil, etc., and oil leakage often occurs at the pipeline connections in the prior art, and the leakage of fuel liquids has a great impact on the safety of automobiles. influences. If the pipe is curved, the curved pipe is more likely to be vibrated and cause oil leakage than the straight pipe. Contents of the invention [0003] The purpose of the present invention is to provide a sealing and anti-leakage device for automobile fluid elbows, which solves the problem that the automobile gas elbows in the prior art are prone to oil leakage; realizes a device that can detect whether the joints of the gas elbows are loose, resulting in...
