进口气动高性能硬密封蝶阀 德国高性能硬密封蝶阀

产品名称：德国进口高性能硬密封蝶阀

进口高性能硬密封蝶阀，采用了“斜置椭圆蝶板径向动平衡密封系统”，实现了蝶板密封圈与阀座密封面之间在关闭之前无摩擦的运动，密封面上压力角大于摩擦角，使蝶板开启阻力极低，快速实现关闭自动吻合密封动作。具有结构先进、密封可靠、寿命长、成本低等优点。是兼备调节、切断两种功能的经济实用自控阀。广泛应用于控制大流量、中低压差、要求泄漏严密的流体。 

1.  偏心尺寸的优化设计，保证启闭过程中，蝶板密封圈与阀座密封面瞬间脱离，实现了蝶板密封圈与阀座密封面之间无磨擦、卡挤，操作力矩小。密封性能好，可以达到零泄漏。 

2.阀座采用堆焊耐蚀合金，产品可靠性高，使用寿命长。 

3.采用专有加工技术，零件精度高，密封环可以在用户现场更换。 

4. 轴承采用特种非金属材料，耐高温性能好，自润滑性强，摩擦力小。能有效防止灰尘和颗粒介质进入阀杆与阀体之间的间隙，避免阀门出现卡死现象。 

5.整体式阀杆和材料采用高强度不锈钢，阀门承受的允用压差大。 

High Performance Hard-Sealed Butterfly Valve 

High performance hard sealed butterfly valve adopts “Inclined oval disc radial dynamic balance sealing system” to attain the frictionless action between the gasket of the disc and the sealing face of the seat before valve closing. The pressure angle is bigger than the friction angle on the sealing face for which the extra-low open resisting force and rapid closing automatic tally sealing action are available. The valve features with advanced construction, reliable seal, long life, low cost,etc. It is an economical practical automatic control valve providing both control and cut-off functions and uses to the fluid services with large flow, low pressure drop and low seat leakage. 

1.The optimum design of eccentric size ensures that the disc’s seal ring can be disengaged from the seat ring sealing surface immediately during the opening and closing process, which leads to no friction, no jamming and small operating torque, and high sealing performance and zero leakage are available. 

2.Corrosion resistant alloy replating is used for seat to make sure high reliability and long service life. 

3.The special processing technology is used for high precision and field-replaceable for seal ring. 

4.Special non-metallic materials are used to make sure high temperature performance, strong self-lubricating and low friction. The dust and granular media can be effectively prevented into the space between the stem and body to avoid jamming. 

5. High-strength stainless steel is used for integral stem and other parts to ensure high allowable pressure differential.
