保溫球閥 |
特點(diǎn) Special point 保溫球閥是一種比較新型的球閥類別，它有著自身結(jié)構(gòu)所的一些*性，如開關(guān)無摩擦，密封不易磨損，啟閉力矩小。主要用糖漿、巧克力、膏體及日化等要求嚴(yán)格切斷的工況。 Insulation ball valve is a relatively new type of ball valve, it has some advantages unique to its own structure, such as no friction switch, seal is not easy to wear, small opening and closing torque. Main use syrup, chocolate, paste and daily chemical and other conditions requiring strict cutting off. 優(yōu)點(diǎn) Optimal point 流體阻力小，其阻力系數(shù)與同長度的管段相等。 結(jié)構(gòu)簡單、體積小、重量輕。 緊密可靠，球閥的密封面材料采用進(jìn)口PTFE、密封性好。 操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。 在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會引起閥門密封面的侵蝕。 適用范圍廣，通徑從DN15-200， 球旋轉(zhuǎn)90度時(shí)，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截?cái)嗔鲃印?/span> The fluid resistance is small and its resistance coefficient is equal to the pipe segment of the same length. Simple structure, small size and light weight. Tight and reliable, the sealing surface of the ball valve is made of imported ptfe with good sealing performance. Easy to operate, quick opening and closing, only 90° rotation from full opening to full closing is needed for remote control. When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes through, it will not cause erosion of the sealing surface of the valve. Wide range of application, diameter from dn15-200, when the ball rotates 90 degrees, all the inlet and outlet should be spherical, thus cutting off the flow. |
