An explosion-proof metal pressure vessel

Abstract

The invention discloses an explosion-proof metal pressure vessel, which comprises a main body. A working chamber is arranged in the main body. The upper wall of the working chamber is communicated with a feeding pipeline with an upward opening, and a movable on-off valve is arranged in the feeding pipeline. In the present invention, during the transportation of the main body, when the transportation environment changes and the air pressure inside the working chamber increases, the gas inflated in the working chamber is guided in one direction by the one-way air pressure valve and then input into the communication pipeline, and then It is input into the storage chamber through the air intake chute and stored, so as to achieve the effect of stabilizing the air pressure inside the working chamber. At the same time, when the gas pressure entering the instantaneous communication pipe is relatively high, when the lifting piston is subjected to a large impact and moves downward , so that the upper and lower sides of the air outlet pipe are connected. At this time, the storage chamber discharges the internal air to the outside through the air outlet pipe, thereby achieving the effect of maintaining the stability of the internal air pressure of the working chamber, thereby improving the overall explosion-proof performance of the main body.

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...
