真空破坏阀“特点”:
1)、真空破坏阀作用于水轮机的后端,当真空度达到本阀的设定值范围 时,阀门开始开启,向管内补气。
2)、本阀阀门采用不锈钢纤焊技术,以保证良好密封效果。
3)、出厂时,按阀门开始开启真空度调整好,(特殊要求时请注明。)

真空破坏阀主要用途:给排水管道和大型水箱;
The vacuum breaking valve main purposes: water supply and drainage pipeline and tank;
工作原理:当管道和水箱内部形成真空时,大气压便会顶开阀盖,大气进入系统内部,平衡系统压力,消除真空影响。
Working principle: when the internal piping and tank vacuum, atmospheric pressure will be the valve cover, air enters the system, balance the system pressure, eliminate the effect of vacuum.

真空破坏阀结构及安装注意事项:
The vacuum breaking valve structure and installation notes:
1. 设备不应安装在有腐蚀性或污染的环境里;
The 1 device should not be installed in a corrosive or polluted environment;
2. 阀体直接安装在配水支管的最高处;
body mounted directly on the top of water distribution pipes;
3. 大气型真空破坏阀的进气口应向下;
atmospheric type vacuum breaking valve inlet should be down;
4. 在有排气阀的时候,真空破坏阀应设置在排气阀的下侧。
when the exhaust valve, vacuum break valve should be arranged in the exhaust valve.
