Pipeline sealing structure capable of achieving high-temperature air leakage safety protection, pipeline sealing method and high-temperature air leakage method

Abstract

The invention belongs to the technical field of pipeline high-temperature air leakage safety protection, particularly discloses a pipeline sealing structure capable of achieving high-temperature air leakage safety protection, a pipeline sealing method and a high-temperature air leakage method. The scheme aims at achieving normal work of pipeline sealing under the working temperature working condition and achieving air leakage for safety protection under the abnormal high-temperature state. According to the specific scheme, the memory inner diameter of a memory pipe joint is smaller than the pipeline outer diameter, so that an air leakage channel can be sealed after heating, and normal pipeline sealing work at the working temperature is guaranteed; and when abnormal high temperature occurs, as the memory length of a memory spring is larger than the distance between a spring check ring and the air leakage channel, enough recovery stroke is achieved, and the memory recovery force is larger than the friction force between the memory pipe joint and the pipeline, the memory spring recovers the memory shape and can drive the memory pipe joint to move, and therefore, the air leakage channel is opened to avoid explosion and other dangers.

Description

technical field [0001] The invention belongs to the technical field of pipeline high-temperature gas leakage safety protection, and in particular relates to a pipeline connection sealing structure capable of realizing high-temperature gas leakage safety protection, and a method capable of simultaneously realizing pipeline sealing and high-temperature gas leakage. Background technique [0002] With the rapid development of science and technology and the increasingly complex battlefield environment, the miniaturization and environmental adaptability requirements of modern weapons and equipment are becoming increasingly stringent. Especially for the pipeline connection of special gases in modern weaponry, it is necessary to realize the functions of pipeline sealing connection in a small space, and at the same time, it also needs to play a role of safety protection in an abnormally high temperature environment. [0003] In terms of pipeline sealing connection, for example, paten...

Problems solved by technology

In an abnormal high temperature environment, the explosive bolt can sense the external temperature through a temperature sensor and detonate the explosive, or detonate the explosive through an active electrical signal. However, the transportation, storage and use of explosives have great safety risks, and the impact load generated by explosive explosion is difficult to be accurate. control
