(耐酸堿,防腐蝕)進口襯氟蝶閥性能描述 Performance description

(耐酸堿防腐蝕)襯氟蝶閥在閥桿軸部的密封。在上下密封軸處采用獨特設計的四級彈性墊與O型圈相結合的密封結構，更適應高溫與低溫使用環境的溫差變化。彈性密封機構體使兩平面不透氣的緊密配合，始終保持最低的操作扭矩。在端面上的襯里提供了比較寬的密封面·閥瓣采用直板式設計最大限度降低流通的阻力，提高在DCS控制系統中調節微動流量的Cv值 RETZ (Acid and alkali resistant and anti-corrosion) sealing of fluorine lined butterfly valve at the stem shaft. The upper and lower sealing shafts adopt a sealing structure of unique design of four stage elastic pads combined with O-rings, which is more suitable for the temperature difference changes in high-temperature and low-temperature service environments. The elastic sealing mechanism body makes the two planes airtight and closely fit, and always maintains the lowest operating torque. The lining on the end face provides a wide sealing surface. The valve disc adopts a straight plate design to minimize the flow resistance and improve the Cv value for regulating the inching flow in the DCS control system
