Guide tracked radial seal system of air preheater gyration

The utility model provides a guide tracked radial seal system of air preheater gyration, through the leak out clearance of seal assembly between to the sector plate of air preheater and radial bafflesealing, the inward one end of seal assembly locates that the center section of thick bamboo of air preheater is gone up, outside one end is connected with the shell body of air preheater is movable,and seal assembly tin rotates along with the center to synchronous with radial baffle, seal assembly becomes the relation of pegging graft with radial baffle in the axial. The utility model disclosesin, the leak out problem that because of radial baffle receive heat altered shape production has been solved through more simple structure to has better sealed effect. 本实用新型提供了种空预器回转导轨式径向密封系统，通过密封组件对空预器的扇形板和径向隔板之间的漏风间隙进行密封，密封组件向内的端设于空预器的中心筒上、向外的端与空预器的外壳体可动连接，密封组件随中心筒起转动，并与径向隔板同步，密封组件与径向隔板在轴向上成插接关系。本实用新型中，通过更为简单的结构解决了因径向隔板受热变形而产生的漏风问题，并且具有更好的密封效果。
