簡介--
天然氣球閥克服普通鑄鋼水用球閥的耐腐蝕性能差、殼體易穿孔的缺點，根據(jù)介質(zhì)具體特性，在閥體材料上選用碳素鋼添加耐蝕合金元素的耐腐蝕碳鋼，閥座密封圈材料聚四氟乙烯（PTFE）對幾乎所有的化學物質(zhì)都是惰性的，且具有摩擦系數(shù)小、性能穩(wěn)定、不易老化、溫度適用范圍廣和密封性能優(yōu)良的綜合性特點。
The natural balloon valve overcomes the defects of poor corrosion resistance and easy perforation of the ordinary cast steel ball valve. According to the specific characteristics of the medium, the corrosion resistant carbon steel is added to the body material to add corrosion resistant alloy elements to the valve body material. The seat sealing ring material polytetrafluoroethylene (PTFE) is inert to all the chemical substances. The utility model has the comprehensive characteristics of small friction coefficient, stable performance, no ageing, wide application range of temperature and excellent sealing performance.
特點--
1、球閥通道平整光滑便于管道掃線清洗,可以輸送漿液及固體顆粒等介質(zhì)。
2、采用PTFE材料作為密封,具有良好潤滑性和彈性,與球體摩擦系小,使用壽命長。
3、啟閉迅速,啟閉時只需把球體轉(zhuǎn)動90度,方便而迅速。
4、流體阻力小,全開時球芯通道和連接管道成直線相通。
5、可設(shè)計成防火型結(jié)構(gòu)。
