进口不锈钢闸阀
Imports of stainless steel gate (gate valve) is the gate opening and closing parts, the direction of movement of the fluid direction perpendicular to the gate, gate can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce ***all quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviati*** arising during processing, this gate board called the flexible gate. Stainless steel gate valve material is divided into 304, 316 stainless steel valve, 321 stainless steel valve. How it works: The gate valve with the valve stem linear movement, called the lift rod valve (also called clear shot valve). Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Imports of stainless steel gate valve mainly used in petroleum, chemical, metallurgy, pharmaceutical and other types of systems.
进口不锈钢闸阀（gate valve）的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关 , 不能作调节和节流。闸板有两个密封面 , ***常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异 , 通常为 50, 介质温度不高时为 2°52' 。楔式闸阀的闸板可以做成一个整 体，叫做刚性闸板；也可以做成能产生微量变形的闸板 , 以改善其工艺性 , 弥补密封面角度在加工过程中产生的偏差 , 这种闸板叫做弹性闸板。不锈钢闸阀材质分为304不锈钢闸阀，316不锈钢闸阀，321不锈钢闸阀。其工作原理：闸阀的闸板随阀杆一起作直线运动的，叫升降杆闸阀 ( 亦叫明杆闸阀)。通常在升降杆上 有梯形螺纹，通过阀门顶端的螺母以及阀体上的导槽，将旋转运动变为直线运动 , 也就是将操作转矩变为操作推力。密封面可以只依靠介质压力来密封 , 即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的 , 即阀门关闭时，要依靠外力强行将闸板压向阀座 , 以保证密封面的密封性。进口不锈钢闸阀主要用于石油、化工、冶金、制药等各类系统中。
