Explosion-proof metal pressure vessel

Abstract

The invention discloses an explosion-proof metal pressure vessel which comprises a main vessel body, a working cavity is formed in the main vessel body, a feeding pipeline with an upward opening is arranged on the upper wall of the working cavity in a communicating mode, and a movable switch valve is arranged in the feeding pipeline. In the transportation process of the main vessel body, when the air pressure in the working cavity is increased due to the change of the transportation environment, expanded air in the working cavity is guided in a one-way mode through a one-way air pressure valve, then is input into a communication pipeline, is input into a storage cavity through an air inlet sliding groove and is stored, and then the effect of stabilizing the air pressure in the working cavity is achieved; and meanwhile, when the pressure of the air entering the communication pipeline instantly is high, a lifting piston is subjected to large impact and moves downwards, the upper side and the lower side of an air outlet pipeline are communicated, the storage cavity exhausts internal air outwards through the air outlet pipeline, then the effect of keeping the internal air pressure of the working cavity stable is achieved, and the overall explosion-proof performance of the main vessel body is improved.

Description

technical field [0001] The invention relates to the technical field of metal pressure vessels, in particular to an explosion-proof metal pressure vessel. Background technique [0002] Metal pressure vessels are used for material storage and transportation, and carry a certain pressure. They are generally used to hold flammable and explosive materials. General metal pressure vessels improve the storage stability by improving the internal airtightness and compressibility. , as an explosion-proof metal pressure vessel, its interior cannot well adapt to the volume change of internal storage substances under different conditions, and for general metal pressure vessels, its internal storage space cannot be changed to adapt to the storage of substances of different qualities, resulting in The effect on its explosion-proof function is weakened. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof metal pressure vessel for overcom...
