特点 Special point 保温球阀是一种比较新型的球阀类别，它有着自身结构所独有的一些优越性，如开关无摩擦，密封不易磨损，启闭力矩小。主要用糖浆、巧克力、膏体及日化等要求严格切断的工况。 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. 优点 Optimal point 流体阻力小，其阻力系数与同长度的管段相等。 结构简单、体积小、重量轻。 紧密可靠，球阀的密封面材料采用进口PTFE、密封性好。 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。 适用范围广，通径从DN15-200， 球旋转90度时，在进、出口处应全部呈现球面，从而截断流动。
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.
