Problems solved by technology

Since the electric propulsion engine itself is charged during its operation, if the engine is in a conduction state with the pipeline supplying propellant, a large part of the electric energy provided to the engine in the test will be dissipated in the pipeline, directly affecting the performance of the engine and even causing engine won't work

Embodiment Construction

[0018] The sealing and insulating pipeline connection mechanism of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The present invention is a sealing and insulating pipeline connection mechanism, such as figure 1 , figure 2 As shown, it includes a straight joint 1, an insulating cap 2, a ball joint 3, an insulating collar 4 and an outer nut 5. The straight-through joint 1 is a circular pipe through-hole structure and has external threads, such as figure 2 As shown, one end of the straight-through joint 1 is a round pipe structure for welding connection with the pipeline, and the other end is an external thread structure for threading connection with the outer nut 5 to connect the two sections of pipeline together.

[0020] The insulating cap 2 plays the role of insulation between the through joint 1 and the ball joint 3, and is a tapered part with a round hole in the middle.

[0021] One end of the ball joint...

Abstract

The invention discloses a connecting mechanism of sealed insulation pipelines, comprising a straight-through joint, an insulation cap, a spherical joint, an insulation sleeve ring and a cap nut. For the pipeline connecting mechanism, the pipelines at two ends are connected in a thread way, the connecting mechanism is sealed in an end surface compression way, and insulation of a ball head joint in the connecting mechanism in the axial and radial direction is realized by adopting insulation parts made of polytetrafluo insulation material, guaranteeing metal pipelines connected with the two ends of the pipeline connecting mechanism to be in insulation state. The connecting mechanism of the sealed insulation pipelines has simple structure and convenient use and has higher application value on the requirement of insulation of the metal pipelines.

Description

Technical field: [0001] The invention relates to pipeline connection and sealing technology, in particular to a sealing and insulation pipeline connection mechanism, and relates to the connection sealing and insulation of liquid and gas transportation pipelines. Background technique: [0002] In chemical, pharmaceutical, petroleum, aerospace and other industrial fields, pipeline transmission is the main way of liquid and gas transportation, and all kinds of transportation pipelines inevitably face the problem of pipeline connection and sealing. Under the guidance of extensive application requirements, the overall level of pipeline connection and sealing technology is almost mature; at the same time, numerous and specific application requirements further promote the presentation and development of new technologies. [0003] During ground testing of various electric propulsion engines, metal piping is often used to supply propellant to the test engine. Since the electric prop...
