进口高性能蝶阀产品概述：

德国《LOCKE》洛克--进口高性能蝶阀采用双偏心结构设计。阀轴双偏离阀体结构中心，同时结合阀板圆弧密封面设计，使阀板在打开时迅速脱离密封座，以减小密封面的摩擦力，阀板在关闭时具有良好的密封性能。中心自定位密封阀座结构设计结合du 特的阀座补偿密封设计，使阀座密封得到有效补偿的同时减少开启、关闭时的摩擦力，大大减小阀门的操作力，有效提高了蝶阀的控制精确度。该系列蝶阀密封性能稳定可靠，使用寿命长。适用于一般腐蚀性气体，液体介质的调节和切断使用。

进口高性能蝶阀产品特点：

1、蝶阀为双向承压，双向金属密封，特殊的结构形式可任意调整密封比压，采用偏心S形锥形阀座密封面，使密封面不易损坏，提高阀门的使用寿命。

2、操作扭矩较小，转90度启闭，轻便迅速。

3、流阻小，具有良好的水力特性，流量特性近似倾斜直线 ，节能效果好，双向密封对水流无方向要求。

Introduction of imported high performance butterfly valve products:

German "Locke" - imported high performance butterfly valve adopts double eccentric structure design. The valve shaft deviates from the structural center of the valve body, and combined with the design of the arc sealing surface of the valve plate, the valve plate is quickly separated from the sealing seat when it is opened, so as to reduce the friction of the sealing surface, and the valve plate has good sealing performance when it is closed. The center self positioning seal seat structure design combined with dute's seat compensation seal design can effectively compensate the seat seal, reduce the friction when opening and closing, greatly reduce the valve operating force, and effectively improve the control accuracy of butterfly valve. This series of butterfly valves have stable and reliable sealing performance and long service life. It is suitable for the adjustment and cut-off of general corrosive gas and liquid medium.

Features of imported high performance butterfly valve:

1. The butterfly valve is bi-directional pressure bearing and bi-directional metal seal. The special structure can adjust the sealing pressure at will. The eccentric S-shaped conical valve seat sealing surface is adopted to prevent the sealing surface from being damaged and improve the service life of the valve.

2. Small operating torque, turn 90 degrees to open and close, light and fast.

3. Small flow resistance, good hydraulic characteristics, flow characteristics approximate inclined straight line, good energy saving effect, bidirectional seal has no direction requirement for water flow.

4. The seal is reliable, and the service life of opening and closing is more than 25000 times.
