Abstract

本发明提供一种阀球，包括球体，球体外壁上附有一层防腐耐磨层，所述防腐耐磨层为PPSU层。所述球体为金属球体或塑料球体。防腐耐磨层采用PPSU(聚亚苯基砜树脂)材料制备可以有效防止阀球生锈，PPSU材料还具有耐高温、耐腐蚀的效果，因此可以解决球阀因为金属球腐蚀而泄漏，或者因为结垢卡死的缺陷。

Description

球阀阀球
技术领域
本发明涉及一种球阀的阀球。
背景技术
球阀(ball valve在海工和船舶领域应为截止阀)，标准GB/T21465-2008《阀门术语》中定义为：启闭件(球体)由阀杆带动，并绕球阀轴线作旋转运动的阀门。在我国，球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业，主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。现有的球阀中的阀球，通常用金属(主要是铜)或者塑料制作，金属阀球存在腐蚀后导致液体泄漏、结垢造成球阀卡死等缺陷，而塑料阀球则具有不耐磨的缺点，本发明试图解决以上问题。
发明内容
本发明提供一种阀球，目的是解决现有技术问题，提供一种耐腐蚀、耐高温、不会生锈的阀球，避免阀球腐蚀后泄漏、结垢造成卡死等缺陷。
本发明解决问题采用的技术方案是：
阀球，包括球体，在球体外壁上附有一层防腐耐磨层。
所述防腐耐磨层为PPSU层。
所述球体为金属球体或塑料球体。
本发明的有益效果：阀球采用PPSU(聚亚苯基砜树脂)材料制备可以有效防止阀球生锈，PPSU材料还具有耐高温、耐腐蚀的效果，因此可以解决球阀因为金属球腐蚀而泄漏，或者因为结垢卡死的缺陷。
附图说明
图1是本发明的结构示意图；
图2是图1的A-A向剖视图。
1.球体、2.防腐耐磨层。
具体实施方式
以下结合附图和具体实施例对本发明做进一步详细说明。
如图1、图2中所示的阀球，包括球体1，在球体外壁上附有一层防腐耐磨层2。本实施例中防腐耐磨层2采用PPSU材料制备，也可以是其他任何适用的材料。其中球体1可以是金属球体，也可以是塑料球体。
聚亚苯基砜树脂(Polyphenylene sulfone resins，PPSU)，是一种无定形的热性塑料具有高度、透明性、高水解稳定性。除强极性溶剂、浓硝酸和硫酸外，对一般酸、碱、盐、醇、脂肪烃等稳定。部分溶于酯酮`芳烃,可溶于卤烃`DM。刚性和韧性好，耐温、耐热氧化，抗蠕变性能优良，耐无机酸、碱、盐溶液的腐蚀，耐离子辐射，无毒，绝缘性和自熄性好，容易成型加工，制品可以经受重复的蒸汽消毒。
防腐耐磨层2采用PPSU材料制备，可在高温情况下使用，且不含重金属，不生锈结垢，耐腐蚀，避免阀球腐蚀而导致球阀泄漏，或者因为结垢卡死的缺陷。
该阀球分别通过20℃1hour,95℃165hour,95℃1000hour测试，测试结果无泄漏、无损坏。

Claims (3)
