Abstract

一种耐腐蚀隔膜阀,由阀杆、阀盖、隔膜、阀体、阀瓣构成,其特征在于:在阀体的过流部位设置热固性熔融结合改性环氧粉末涂料的涂层。本实用新型成本低,耐腐蚀性能好,且能实现大型化。

Description

一种耐腐蚀隔膜阀
本实用新型涉及阀门技术,特别提供了一种耐腐蚀隔膜阀。
隔膜阀是种应用很多的过流部件,在石油、化工、煤矿、化纤、造纸、热电等行业中普遍使用,为解决特殊介质环境中的腐蚀问题,通常用高成份的合金钢制作阀体,大大增加了成本,特别在隔膜阀的尺寸较大时。
本实用新型的目的在于提供一种耐腐蚀的隔膜阀,其成本低,且能实现大型化。
本实用新型提供了一种耐磨耐蚀隔膜阀,由阀杆(1)、阀盖(2)、隔膜(3)、阀体(4)、阀瓣(6)构成,其特征在于:在阀体(4)的过流部位设置热固性熔融结合改性环氧粉末涂料的涂层(41)。本实用新型提供的隔膜阀在保证现有隔膜阀结构尺寸标准不变的情况下,在阀体的过流部件施涂以热固性熔融结合环氧粉末涂料,由于该种涂料有良好的耐腐蚀性,与金属表面结合性能极好,且表面光洁度高,其一方面可以降低水阻,另一方面可以通过阀体基体采用普通碳钢而大大降低成本,特别适用于大尺寸的,用于特殊酸碱环境下的隔膜阀。下面结合附图通过实施例详述本实用新型。
附图1为隔膜阀结构示意图。
实施例
如图1所示,隔膜阀由阀盖(2)、阀体(4)、带手柄(5)的阀杆(1)、隔膜(3)构成,带手柄(5)的阀杆(1)置放于阀盖(2)内,阀杆(1)底部接有一半球形阀瓣(6);阀盖(2)、阀体(4)中间置硅橡胶或氟塑料隔膜(3)用螺母夹紧固定;阀体(4)为普通碳钢件,过流部件施涂SEBF涂料层(41),本实用新型可在-40℃~100℃范围内,酸碱等介质中长期使用,不老化、开裂。
