Abstract

本实用新型涉及一种渣浆阀门的改进，包括阀体、置于阀体内的旋塞和可控制旋塞转动的手柄，阀体与旋塞配合面为锥面，其特征在于旋塞过流孔的尺寸形状与阀体过流面相同，阀体底部设有承重螺钉，顶部设有可紧固旋塞的锁紧螺柱。本实用新型操作省力，抗磨损性和密封性好，因而使用寿命长。

Description

抗磨损旋塞渣浆阀门
本实用新型涉及一种渣浆阀门的改进。
火力发电厂的水力除灰系统和化工、造纸、矿山等工业生产中，渣浆(砂浆、污水等)阀门由于抗磨损和密封性较差，因而发生磨损后漏流等现象，对生产的影响很大。特别是使用低值煤作燃料的火电厂，粉煤灰中高硬度物质较多，对渣浆阀门的磨损更严重，一般使用寿命仅2-3个月。
本实用新型的目的是提供一种抗磨损和密封性能好的渣浆阀门。
本实用新型的方案是：包括阀体、置于阀体内的旋塞和可控制旋塞转动的手柄，阀体与旋塞配合面为锥面，其不同之处是旋塞过流孔的尺寸形状与阀体过流面相同，阀体底部设有承重螺钉，顶部设有可紧固旋塞的锁紧螺柱。
本实用新型开启时，因过流面的尺寸、形状完全与管道相同，使流体流态不发生变化，流阻小，且大大减小了对阀门的冲蚀，使之抗磨损性能好；使用的旋塞结构使旋塞和阀体之间贴合紧密封性好；阀门动作之前，先松开锁紧螺柱，再由承重螺钉上顶一段距离，使旋塞和阀体间形成一个间隙，故操纵省力；本阀门零件少，结构简单，装拆方便，易于维护。
附图为本实用新型结构示意图。
阀体2内设旋塞3，手柄6与旋塞相连并可控制旋塞旋转。锁紧螺柱1位于阀体顶部，承重螺钉4位于阀体底部。旋塞为与阀体内腔相配合的圆锥台形。
