Abstract

本实用新型涉及一种隔膜阀用凸型隔膜,包括隔膜垫、隔膜片、销钉,隔膜片为凸型盆状结构且销钉嵌入在隔膜片中心成一体,隔膜垫为中心有一圆孔且和隔膜片同弧度的凸型盆状结构,隔膜垫套装在隔膜片的销钉上构成凸型隔膜。的隔膜垫的材质为三元乙丙橡胶,隔膜片的材质为改性聚四氟乙烯。本实用新型技术特点为隔膜片压制密度高、结构强度大、耐腐蚀性能更强,因而寿命长和质量高。

Description

隔膜阀用凸型隔膜
技术领域
    本实用新型涉及一种隔膜阀用隔膜,特别涉及一种隔膜阀用凸型隔膜。 
背景技术
目前,我公司现有桑达斯隔膜阀的隔膜及隔膜垫的形状为凹型结构,在隔膜制造工艺上,其中部销钉凸台处在烧结和压制密度较低处,工艺难度大、成品率低、寿命短。 
发明内容
   鉴于以上存在的技术问题,本实用新型提供一种隔膜阀用凸型隔膜,具体技术方案是,一种隔膜阀用凸型隔膜,包括隔膜垫、隔膜片、销钉,其特征在于:所述的隔膜片为凸型盆状结构且销钉嵌入在隔膜片中心成一体,隔膜垫为中心有一圆孔且和隔膜片同弧度的凸型盆状结构,隔膜垫套装在隔膜片的销钉上构成凸型隔膜。 
所述的隔膜垫的材质为三元乙丙橡胶,隔膜片的材质为改性聚四氟乙烯。 
本实用新型技术特点为隔膜片压制密度高、结构强度大、耐腐蚀性能更强,因而寿命长和质量高。 
附图说明
图1为本实用新型结构示意图。 
图2为本实用新型在隔膜阀中的装配图 
具体实施方式
    如图1、图2所示,隔膜垫1的材质为三元乙丙橡胶,隔膜片2的材质为改性聚四氟乙烯,隔膜片2压铸成凸型盆状结构且销钉3同时嵌入在隔膜片2中心成一体,隔膜垫1压铸成为中心有一圆孔且和隔膜片2同弧度的凸型盆状结构,隔膜垫1套装在隔膜片2的销钉3上构成凸型隔膜。 
凸型隔膜通过销钉6与阀芯、阀杆4连接;凸型隔膜通过螺栓与阀盖5、阀体8紧固。当气源进入隔膜阀膜盖,在气源压力的作用下,带动阀杆4、阀芯7向上运动,使凸型隔膜向上拔起打开阀门;当气源压力为“零”时,隔膜阀靠内弹簧力复位,使阀杆4、阀芯7向下运动,凸型隔膜向下翻,压住阀体8堰面,关闭阀门。
