Abstract

耐磨排渣闸阀由阀体、闸板阀芯、闸阀提拉丝杆、密封函装置,手轮构成,阀体腔壁面和阀体闸板嵌口镶装有耐磨陶瓷面层,闸板板面镶装有耐磨陶瓷面层。特点是耐磨性强,使用寿命长,为现有排渣闸板使用寿命的3倍以上。

Description

耐磨排渣闸阀
本实用新型涉及一种闸板阀门。
目前发电厂除灰系统使用的金属制排渣闸阀尽管较通常使用的闸板阀具有较强的耐磨性,但是由于排灰过程中灰浆渣粒的强力磨擦而很快损坏,致使其使用寿命短,维修、更换频繁,给正常的发电生产运行及除灰操作带来了极为不利的影响。
本实用新型的目的是提供一种适于发电厂除灰系统使用的,耐磨性强、使用寿命长的耐磨排渣闸阀。
本实用新型的目的是通过下述方式实现的,由金属制阀体、闸板阀芯、闸板提拉丝杠,密封函装置、手轮构成的闸板阀的阀体腔壁面及阀体闸板嵌口镶装耐磨陶瓷面层,闸板朝向闸阀进口一侧板面上镶装耐磨陶瓷面层,闸阀与灰浆接触部位表面的耐磨性能增强,使闸阀使用寿命延长。
耐磨排渣闸阀的进一步完善是,闸阀闸板朝向闸阀出口一侧板面上镶装有耐磨陶瓷面层,使闸阀闸板全部板面被耐磨陶瓷面层遮盖而与灰浆隔离使排渣闸阀使用寿命进一步提高。
本实用新型所提供的耐磨排渣闸阀的耐磨陶瓷面层可采用氧化锆基耐磨陶瓷、氧化铝基耐磨陶瓷、碳化硅基耐磨陶瓷、莫来石基耐磨陶瓷、氮化硅基耐磨陶瓷中任意一种制作。
本实用新型提供的耐磨排渣闸阀的与灰浆接触面镶装有具有极强耐磨性的耐磨陶瓷保护面层,从而提高了阀门的耐磨性,大大提高了排渣闸阀的使用寿命,与现有金属制排渣闸阀比较,使用寿命可提高3倍以上。
附图是本实用新型的实施例,下面结合实施例进一步说明本实用新型。
图1为耐磨排渣闸阀的结构图。
耐磨排渣闸阀如图所示,由阀体(3)、闸板阀芯(5)、闸板提拉丝杠(9)、密封函装置(2)、手轮(1)构成的闸板阀的阀体腔壁面和阀体闸板嵌口镶装有耐磨陶瓷面层(4)、(1),闸板两侧板面镶装有耐磨陶瓷面层(6)、(8),使闸阀与灰浆接触面被耐磨性极强的耐磨陶瓷面层遮盖而使金属面与灰浆隔离,使阀门使用寿命延长。
耐磨排渣闸阀耐磨陶瓷面层采用氧化锆基耐磨陶瓷、氧化铝基耐磨陶瓷、碳化硅基耐磨陶瓷、莫来石基耐磨陶瓷、氮化硅基耐磨陶瓷中任意一种制作。
