【技术实现步骤摘要】
一种气动疏水阀
本专利技术涉及一种环保设备,尤其涉及一种气动疏水阀。
技术介绍
疏水阀通常是可调疏水阀,广发用于热电厂机组主蒸汽、再热、低压旁路、抽汽等汽水系统中,目前的调节通常是粗犷调节,为了改善调节精度目前通常是在螺纹螺距的设计下功夫,但其调节的精度还是不能够达到一个满意的效果,同时由于蒸汽的压力非常巨大,阀瓣在上下被调节移动时上下两端的压差使得感觉调节非常沉重,加大了精确调节的难度。
技术实现思路
本专利技术为了解决以上问题提供了一种结构简单、动作灵敏、排水温度恒温、节能环保、无噪音、安装维修方便、自动排气的气动疏水阀。本专利技术的技术方案是:所述的疏水阀包括阀体、阀座、阀芯、导向套、密封圈、阀盖、连杆、支架、推杆、弹簧、气膜和膜盖,所述的阀座固定连接在阀体上,所述的阀芯设置在阀座上,所述的导向套设置在阀座内,所述的导向套外围设置密封圈,所述的阀盖连接在阀座上部,所述的支架连接在阀盖上部,所述的膜盖连接在支架上部,所述的气膜和弹簧设置在膜盖内,所述的连杆和推杆设置在支架内,所述的支架倾斜45°设置,所述的推杆前部连接连杆,后部连接弹簧。本专利技术结构简单、动作灵敏、排水温度恒温、节能环保、无噪音、安装维修方便、自动排气。附图说明图1是本专利技术的结构示意图。图中1是阀体,2是阀座,3是阀芯,4是导向套,5是密封圈,6是阀盖,7是连杆,8是支架,9是推杆,10是弹簧,11是气膜,12是膜盖。具体实施方式一种气动疏水阀,所述的疏水阀包括阀体1、阀座2、阀芯3、导向套4、密封圈5、阀盖6、连杆7、支架8、推杆9、弹簧10、气膜11和膜盖12,所述的阀座2固定连 ...
