    BLW3高性能硬密封蝶阀

    BLW3高性能硬密封蝶阀

      BLW3高性能硬密封蝶阀,密封面是采用圆锥面型式,在水平中心上有一个角度偏心,阀杆相对于流道中心在其轴向和径向上有两个距离偏心,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。

      本产品符合GB/T4213-2008标准。

    BLW3 High performance hard sealed butterfly valve, whose sealing surface is a conical type, has an eccentric angle in the horizontal center, the valve stem relative to the flow channel center has two distance biases in its axial and the radial direction, thus the frictionless action between the gasket of the disc and the sealing face of the seat before valve closing is available. The pressure angle is larger than the friction angle on the sealing face to realize the extra-low open resisting force and rapid closing automatic tally sealing action. 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 dro and low seat leakage.

    The product complies with GB/T4213-2008 standard.
