进口气动法兰角座阀 不锈钢头 塑料头 气动蒸汽角阀

 

品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……气动角座阀是指利用执行器活塞来提供线性作用力推动阀芯离开阀座的一种气控阀门。角座阀尤其适用于高温且流量要求较大的流体环境下，如蒸汽或者水。角座阀中某些型号，如果反向安装，运行时会克服水锤作用 retz Pneumatic angle seat valve refers to a type of pneumatic valve that uses the actuator piston to provide linear force to push the valve core away from the valve seat. Corner seat valves are particularly suitable for fluid environments with high temperatures and high flow requirements, such as steam or water. Some models of angle seat valve will overcome Water hammer during operation if installed in reverse direction   

进口气动法兰角座阀产品详情product details

可以在任何方向安装∶横向，纵向，倾斜。

双动型和单动型产品能提供的口径规格从3 /8 英寸到4 英寸，可从阻塞锤上下两端关闭，而单动型阀门从阻塞锤下端开启

进口气动法兰角座阀工作原理 working principle

1.单作用：由一个二位三通电磁阀控制。导向介质压力进入执行器，作用于活塞，使阀芯穿梭于阀腔中实现打开或关闭阀门。阀芯复位通常是借助于气动执行器中的弹回弹簧来完成。Single acting: controlled by a two position three-way solenoid valve. The pressure of guiding medium enters the actuator and acts on the piston to make the valve core shuttle in the valve chamber to open or close the valve. The valve element reset is usually completed by means of the spring in the pneumatic actuator.

双向常闭（N.C.）Two way normally closed (N.C.)介质从阀芯下方流入，可避免水锤作用。介质在阀芯上方流入，将受到水锤挤压;The medium flows under the valve core to avoid the action of water hammer. If the medium flows above the valve core, it will be squeezed by water hammer;

常闭型（N.C.）介质从阀芯上方流入，介质从阀芯上方流入会造成"水锤"效应Normally closed (N.C.) medium flows from above the valve core, which will cause "water hammer" effect

常开型（N.O.）介质从阀芯下方流入Normally open (N.O.) medium flows from below the valve core

2.双作用：配置的阀门中，没有弹回弹簧，导向介质既用来打开阀门，也用来关闭阀门。

Double acting: there is no spring in the configured valve, and the guiding medium is used to open and close the valve.
