Sealing element for aviation pipeline

Abstract

The invention discloses a sealing element for an aviation pipeline. The sealing element comprises a pipeline connecting piece, an oil inlet pipe and an oil outlet pipe, wherein the oil inlet pipe is fixedly installed on one side of the outer portion of the pipeline connecting piece in a clamped mode; the oil outlet pipe is fixedly installed on the other side of the outer portion of the pipeline connecting piece in a clamped mode; a heating mechanism is installed in the pipeline connecting piece in an embedded mode; and the heating mechanism comprises a supporting pipe, a water inlet pipe, a return pipe, a curved circulating pipe, a heat conduction silicone grease layer and an asbestos heat preservation layer. According to the sealing element, liquid for cooling and heat absorption of an aero-engine is guided into the curved circulating pipe through the water inlet pipe, a hollow inner container in the supporting pipe is heated through the curved circulating pipe and the heat conductionsilicone grease layer, the asbestos heat preservation layer is matched to preserve heat in the supporting pipe, and the return pipe is used for returning heated liquid, so that the heating function of a pipeline in the pipeline connecting piece is realized, and the problems that oil in the pipeline connecting piece is liable to being solidified since the pipeline connecting piece is influenced bythe low temperature of the external environment is solved.

Description

technical field [0001] The invention relates to the technical field of aviation pipe fittings, in particular to a sealing element for aviation pipelines. Background technique [0002] The seal is a material or part that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from intruding into the internal parts of the machine equipment. Although the rubber and plastic seal is small, its function makes it a The basic components and accessories in the main industries of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing occupy a very important position in the development of the national economy. [0003] However, when the existing seals for aviation pipelines are used, the pipeline connectors are affected by the low temperature of the external environment, which may easily cause the oil inside the pipeline connectors to sol...

Problems solved by technology

[0003] However, when the existing seals for aviation pipelines are used, the pipeline connectors are affected by the low temperature of the external environment, which may easily cause the oil inside the pipeline connectors to solidify, resulting in blockage of aviation pipelines and long-term use of the connecting rubber hose. After the pipeline is aged and damaged, it is easy to cause the leakage of aviation pipeline liquid
