?進(jìn)口真空截止閥描述--

RETZ真空截止閥用途廣泛，適用于工作溫度≤425℃和≤550℃，可用于半真空，中級，高級真空條件下。作為啟閉裝置，尤其適用于火電廠汽機(jī)冷凝和真空負(fù)壓系統(tǒng)。

RETZ vacuum cut-off valves are widely used for working temperatures of less than 425 degrees centigrade and less than 550 degrees Celsius. They can be used in semi vacuum, intermediate and advanced vacuum conditions. As an opening and closing device, it is especially suitable for steam turbine condensing and vacuum negative pressure systems in thermal power plants.

?進(jìn)口真空截止閥設(shè)計(jì)特點(diǎn)--

1.啟閉迅速，扭拒小

2.安裝長度短，傳導(dǎo)系數(shù)大

3.密封面運(yùn)動(dòng)摩擦力小，啟閉輕便，而且密封面磨損有自動(dòng)補(bǔ)償功能。

4.閥蓋調(diào)料室設(shè)有真空密封結(jié)構(gòu)，具有自脹壓緊作用，并且密封采用高強(qiáng)膨脹材料密封，使系統(tǒng)與大氣*隔離，具有很好的系統(tǒng)氣密性。
