简介--
天然气球阀克服普通铸钢水用球阀的耐腐蚀性能差、壳体易穿孔的缺点,根据介质具体特性,在阀体材料上选用碳素钢添加耐蚀合金元素的耐腐蚀碳钢,阀座密封圈材料聚四氟乙烯(PTFE)对几乎所有的化学物质都是惰性的,且具有摩擦系数小、性能稳定、不易老化、温度适用范围广和密封性能优良的综合性特点。
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.
特点--
1、球阀通道平整光滑便于管道扫线清洗,可以输送浆液及固体颗粒等介质。
2、采用PTFE材料作为密封,具有良好润滑性和弹性,与球体摩擦系小,使用寿命长。
3、启闭迅速,启闭时只需把球体转动90度,方便而迅速。
4、流体阻力小,全开时球芯通道和连接管道成直线相通。
5、可设计成防火型结构。
