Advantages of toothed quick-opening pressure vessel
The toothed quick-opening pressure vessel has the advantages of fast opening and closing, strong pressure-bearing capacity, and wide applicable pressure range. It is widely used in chemical, petroleum, food, medical and other industrial fields. Its working principle is to machine uniformly distributed teeth in the circumferential direction of the toothed quick-opening device. Through the meshing and staggering between the teeth, the purpose of rapid opening and closing is achieved. The axial force is borne by the flange of the kettle body, and the teeth and The transmission of the contact surface between the teeth is a typical contact problem, and the accurate calculation of stress and deformation is quite complicated. At the same time, due to the semi-intermittent operation of the container, frequent opening, shutdown and pressure fluctuations make the stress in the container change periodically with time, which puts forward higher requirements on the anti-fatigue performance of the container.
