气动偏心旋转调节阀(HD6P65H)
Pneumatic eccentric rotary regulating valve
一、概述/ Summary:
气动
偏心旋转调节阀(也称“
凸轮挠曲阀”),由气动活塞式执行机构和偏心旋转阀及定位器等附件组配而成。它充分利用了阀内件的偏心旋转之特点,让流道更通畅,且自清洁能力大幅提升。加上我们对阀座、旋转阀芯等阀内件表面的特殊硬化处理,提升了其抗腐蚀和颗粒高速冲刷的性能,非常适合煤气化等工艺系统中,用于控制水煤浆、回水、油浆等颗粒状介质的调节和控制。
Pneumatic eccentric rotary regulating valve is composed of pneumatic piston actuator, eccentric rotary valve, positioner and other accessories. It makes full use of the eccentric rotation feature of the valve trim, makes the flow channel more smooth, and greatly improves the self-cleaning ability. In addition, our special hardening treatment on the surface of valve seat, rotary valve core and other internal parts improves its corrosion resistance and particle high-speed scouring performance, which is very suitable for coal gasification and other process systems, to control the adjustment and control of coal water slurry, backwater, oil slurry and other granular media.
