electric knife gate valve of penetrade

电动穿透式刀闸阀是一种闸板与阀座始终紧密接触密封的阀门，其原理是闸板上开有一个通径大小的圆口，通过闸板启闭使得闸板上圆口跟通径做*脱离和相吻合的动作。此阀门的优点在于阀体通径无凹槽，介质不会卡阻堵塞，并且具有全通径流通特性，适合粉体颗粒介质的管道中使用。其密封结构可以分软密封、硬密封结构。穿透式刀闸阀是具有精密构造，工艺性好，结构紧凑等特点，密封阀座为活动结构设计，有防磨损和自动补偿功能，因而寿命更长。在关闭和开启过程中阀座跟闸板一直紧贴运动，使得阀门启闭力稳定，并且具有切断介质等特点。该阀门配电动执行器可实现远程微电脑控制。在电源供应中断时，也可以通过手动来操作阀门启闭，从而紧急控制了介质的流向，也避免了事故的发生。也可以使用现场电控箱、远程PLC电动智能控制等附件来操作和调试的控制。用户可根据实际需要进行选择。

Electric penetration knife gate valve ,gate closely contacts with the seat , Principle is that there is a diameter size of circular port in the gate ,opening and closing gate makes circular port takes off and consistent action with diameter .

The advantages of this valve are : body's diameter without grooves, the medium does not plug the card blocking, full-diameter flow characteristics, suitable for powder using in the pipeline. The sealing structure can be divided into soft-seal and hard seal structure. Penetrable Knife Gate Valve is a sophisticated structure, good technology , compact structure, etc, activities of structural design of sealing seat , anti-wear and automatic compensation function and long age. Gate keeps closely movement with gate when opening and closing ,makes valve open and close stability and cuts off the media, and so on.

Equipped with electric actuator,it can be remote microcomputer control. When power cut off, you can also manually operate the valve opening and closing to control media flowing , also to avoid accidents. You can use on-site electronic-control box, remote PLC inligent control and other accessories to operate and debug controlling. Users can choose based on actual needs.
