Abstract: A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.

Abstract: A heat dissipation system for a high-speed train running in a low-vacuum tube is provided. Component groups that provide power and resistance for the movement and stop of a train are provided at a periphery, close to the train, in a low-vacuum tube. The component group is provided with a group A cooling assembly. The group A cooling assembly includes a group A cooling-type heat exchanger and/or a group A nozzle assembly attached to the back of the component group. Since the friction between the train running at high speed and the air in the low-vacuum tube and the operation of the key equipment in the low-vacuum tube will generate a lot of heat, the group A cooling assembly in the component group in the low-vacuum tube exchanges the heat with the air in the low-vacuum tube.

Abstract: An integrated production system for a ternary material includes an agitating device, a water washing tank, an agitated nutsche filter and a dryer arranged in sequence along a travel path of a ternary material, where the agitating device is used to agitate a material; the water washing tank is used to carry out even pulping and provide a reaction space; the agitated nutsche filter is used to realize an agitating and filtering operation on the material; the dryer is used to dry the material. The integrated production system can meet the high requirements of the large-scale ternary material production for the water content, washing effect, particle crystal form, purity and closed operation. The integrated production system can also effectively ensure the production capacity and production efficiency of the system while satisfying the requirements of green manufacturing for efficiency enhancement, energy saving, consumption reduction and emission reduction.
