Abstract

本实用新型涉及一种隔膜阀,包括阀体、阀杆、阀盖、阀瓣和隔膜、阀盖内的阀杆和阀瓣相连接,阀盖固定在阀体上,阀体内衬聚四氟乙烯层,隔膜与阀瓣之间设置隔膜垫,隔膜和隔膜垫的四周紧固在阀盖和阀体之间,隔膜由聚四氟乙烯材制制成。本实用新型克服了现有的隔膜阀密封不严密,防腐性能较差的缺陷,具有结构简单、关闭严密、密性性能可靠、耐腐蚀性能强、使用寿命长的优点。

Description

隔膜阀
本实用新型涉及一种隔膜阀。
隔膜阀是专用于控制腐蚀性介质的耐腐蚀阀门。它的特点是用橡胶或塑料隔膜使介质和其它驱动零件处于隔离状态,即能起到密封作用,又有防腐效果。然而由于传统结构的局限,如果碰到腐蚀性较强的介质,其密封性能就极不稳定,防腐作用也大为降低,严重的甚至不能使用。
本实用新型的目的是克服现有技术的上述缺陷,从而提供一种结构简单,密封严密,防腐性能强的隔膜阀。
本实用新型包括阀体、阀杆、阀盖、阀瓣和隔膜,阀盖内的阀杆和阀瓣相连接,阀盖固定在阀体上,阀瓣下侧的隔膜四周紧固在阀盖和阀体之间,阀体内衬聚四氟乙烯层,隔膜与阀瓣之间设置隔膜垫,隔膜垫的四周同样紧固在阀盖和阀体之间。
隔膜由聚四氟乙烯材料制成。
以下结合附图和实施例说明本实用新型的详细内容。
附图是本实用新型的结构示意图。
如图所示,本实用新型包括阀体1、阀杆2、阀盖3、阀瓣4和隔膜5,阀盖3内的阀杆2和阀瓣4相连接,阀盖3固定在阀体1上,阀体1内衬聚四氟乙烯层6,其厚度为3-4毫米。隔膜5与阀瓣4之间设置隔膜垫7,隔膜5和隔膜垫7的四周紧固在阀盖2和阀体1之间,隔膜5由聚四氟乙烯材料制成,隔膜垫7采用耐酸橡胶,阀体1内衬的聚四氟乙烯层6可以延伸到两端法兰上。
本实用新型通过上述具体设计,具有结构简单、关闭严密、密封性能可靠,耐腐蚀性能好、使用寿命长的优点。
