【产品名称:对夹蝶式止回阀】

【产品型号:H76H、H76X】

    上海杰一阀门H76H对夹蝶式止回阀适用于公称压力PN1.6Mpa~42.0Mpa、Class150~2500LB;公称通径DN15~1200mm、PNS1/2~48";工作温度:-196~540℃的各种管路上,用于防止介质倒流。阀体材料有:碳钢、不锈钢等,可使用于水、蒸汽、燃气、油品、酸类介质等。

【产品介绍】:
    上海杰一阀门H76H对夹蝶式止回阀阀座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。用于工业、环保、水处理、高层建筑给排水管路,阻止介质逆向流动之用。

【工作原理】:
    H76H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。

【产品特点】:
1、阀体结构长度尺寸小、刚性好。
2、使用性能安全可靠,抗干扰性好。
3、达到完全密封,水压试验泄漏量为零。
4、体积小、重量轻、结构紧凑、便于维护。
5、因速闭作用,可防止介质倒流,消除水锤作用强。
6、安装方便,可在水平、垂直两个方向的管路上安装。
7、阀板采用对偶板上加两个扭力弹簧的设计,可使阀板自行速闭。
