星图挂机软件_H76H对夹蝶式止回阀
H76H对夹蝶式止回阀产品介绍:
,(又名:对夹双瓣止回阀)采用短型结构尺寸和双阀瓣设计。相比传统的旋起式止回阀,该系列阀门具有无外泄露、可任意位置安装、密封性能好、线性震动小、压降小和零座圈磨损优势。蝶式止回阀用于纯净管路及工业、环保、水处理、高层建筑给排水管路,阻止介质逆向流动之用。该止回阀采用对夹式,蝶板为两个半圆,且采用弹簧强制复位,密封面可为本体堆焊耐磨材料或衬橡胶,使用范围广,密封可靠。对夹蝶式止回阀蝶板为两个半圆,且采用弹簧强制复位,由于扭弹簧的作用力通常阀门是关闭的,当流体正向流动时,流体的压力使得碟片绕铰链转动,阀门打开。一旦流体流动停止,由于弹簧的作用,在倒流前阀门就已关闭。
H76H对夹蝶式止回阀产品特点:
1、双阀瓣设计
2、重量轻、结构紧凑
3、双弹簧作用阀瓣设计
4、软密封或金属密封阀座圈设计
