真空破壞閥“特點(diǎn)”:
1)、真空破壞閥作用于水輪機(jī)的后端,當(dāng)真空度達(dá)到本閥的設(shè)定值范圍 時(shí),閥門開始開啟,向管內(nèi)補(bǔ)氣。
2)、本閥閥門采用不銹鋼纖焊技術(shù),以保證良好密封效果。
3)、出廠時(shí),按閥門開始開啟真空度調(diào)整好,(特殊要求時(shí)請(qǐng)注明。)

真空破壞閥主要用途:給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:當(dāng)管道和水箱內(nèi)部形成真空時(shí),大氣壓便會(huì)頂開閥蓋,大氣進(jìn)入系統(tǒng)內(nèi)部,平衡系統(tǒng)壓力,消除真空影響。
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.

真空破壞閥結(jié)構(gòu)及安裝注意事項(xiàng):
The vacuum breaking valve structure and installation notes:
1. 設(shè)備不應(yīng)安裝在有腐蝕性或污染的環(huán)境里;
The 1 device should not be installed in a corrosive or polluted environment;
2. 閥體直接安裝在配水支管的******處;
body mounted directly on the top of water distribution pipes;
3. 大氣型真空破壞閥的進(jìn)氣口應(yīng)向下;
atmospheric type vacuum breaking valve inlet should be down;
4. 在有排氣閥的時(shí)候,真空破壞閥應(yīng)設(shè)置在排氣閥的下側(cè)。
when the exhaust valve, vacuum break valve should be arranged in the exhaust valve.
