Problems solved by technology
[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to solve the reliability and working stability of the moving mechanism for fast blocking and circulation of tungsten alloy ball particles with a diameter of less than 1mm in the ADS spallation target when the vacuum pipeline flows The technical problem is to provide a metal particle less than 1mm in a vacuum state that can effectively block and circulate quickly when flowing, and has high stability and reliability, and can completely avoid the phenomenon of material jamming and cutting. It is used in a vacuum state Gate valve for rapid blocking and circulation of metal particles

The invention discloses a gate valve for achieving rapid blockage and circulation in the flowing process of metal particles in a vacuum pipe. By means of the gate valve, the problems that in the priorart, materials are likely to be stuck, and the single-suspension-arm phenomenon exists when a valve plate moves on a valve seat, so that moving stability and reliability of the valve plate are affected are solved. The gate valve is characterized in that a combined valve plate is mounted at the output end of a valve plate driving device, wherein the combined valve plate is composed of a metal valve plate and a graphite valve plate; the metal valve plate is provided with a discharging opening; a cylindrical baffle is connected to the inner wall of a feeding flange; the metal particles are prevented from entering a moving gap for the first time through the cylindrical baffle; spring tightly-pressing mechanisms are mounted at the two sides of the feeding flange and the two sides of a discharging flange correspondingly; and rectangular baffles in the spring tightly-pressing mechanisms play a role in tightly pressing the combined valve plate, and the metal particles are prevented from entering the moving gap for the second time. The gate valve has the beneficial effects that no stuck phenomenon is caused; the phenomenon that the metal particles are broken or crushed is avoided; the moving stability and reliability of the combined valve plate are improved; and thus, the service life of the gate valve is prolonged.
Description
technical field [0001] The invention belongs to the technical field of vacuum equipment, in particular to a moving mechanism for fast blocking and circulation of ADS spallation target metal particles flowing in a vacuum pipeline, and in particular to a slide valve for fast blocking and circulation of metal particles in a vacuum pipeline. Background technique [0002] ADS (Accelerator Driven Radioactive Clean Nuclear Energy System) has become the choice of the new generation of nuclear energy due to its good resource efficiency, environmental efficiency and safety efficiency, and has become a research hotspot in the world in recent years. The spallation target is a key and technically difficult important part of the system. In the prior art, the gate valve used for fast blocking and circulation of ADS spallation targets when metal particles flow in the vacuum pipeline includes a valve seat and a valve plate installed in the valve seat, and a valve plate support block is insta...
