【簡(jiǎn)單介紹】
【詳細(xì)說(shuō)明】
性能規(guī)范Property specification用途及特點(diǎn)Purpose and characteristic 伸縮蝶閥適用于溫度≤80℃，公稱壓力≤1.6MPa的食品、醫(yī)藥、化工、石油、電力、輕紡、造紙等給排水、氣體管道上作調(diào)節(jié)流量和截流介質(zhì)的作用，具有補(bǔ)償管道熱脹冷縮的功能。其主要特點(diǎn)為：
- 設(shè)計(jì)新穎、合理、結(jié)構(gòu)*，重量輕，操作方便，啟閉迅速;
- 伸縮蝶閥除了能作調(diào)節(jié)和截流作用，補(bǔ)償管道溫差所產(chǎn)生的熱脹冷縮功能外，還能為安裝更換、維修閥門提供方便；
- 密封部位可調(diào)節(jié)更換，密封性能可靠等特點(diǎn)。
escopic butterfly valve is suitable for water supplying, gas pipe as adjust flux and cut off medium in foodstuff, pharmacy,
Chemical industry, petroleum, electric power, light textile, paper making etc. with temperature＜80C，nominal pressure＜1.6MPa, and has function of compensation pipe expand with heat and contract with cold, the main characteristic as below:
- Novel and reasonable design, particular configuration, light and easy to operate and start and stop rapidly.
- Besides adjust and cut off currency, compensate temperature differential in pipe, which cause function of expansion with heat and extraction with cold flexible butterfly valve can provide convenience for installation exchange, maintenance.
- It has characteristic of hermetical components can adjust and replace, reliable hermetic capability etc.
