进口闸阀的基本工作原理《值得收藏》
时间:2020-06-07 22:37 点击次数:
进口闸阀的启闭件是闸板,可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。闸板的运动方向与流体方向相垂直,进口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, 比较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 。闸阀驱动方式分类:手动闸阀,气动闸阀,电动闸阀。
 
The gate valve is used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The movement direction of the gate is perpendicular to the direction of the fluid. The inlet gate valve can only be fully opened and fully closed, and can not be adjusted and throttled. There are two sealing surfaces on the ram. The two sealing surfaces of the most commonly used ram valve form wedges, and the wedge angle varies with the valve parameters. Gate valve driving mode classification: manual gate valve, pneumatic gate valve, electric gate valve.
 
进口闸阀的基本工作原理有以下两个程序:
 
The basic working principle of the import gate valve is as follows:
 
一 . 进口闸阀关闭程序:
 
1手轮转动的比较后几圈,阀杆底部的角形平面机械地楔向压迫球体,使其紧密地压在阀座上,
达到完全密封。
 
2关闭时,顺时针旋转手轮,阀杆开始下降并使球体离开阀座开始旋转。
 
3继续旋转手轮,阀杆受到嵌于其上螺旋槽内的导销的作用,使阀杆和闸板同时旋转90°。
 
4快要关闭时闸体已在与阀座无接触的情况下旋转了90°。
 
1、 Inlet gate valve closing procedure:
 
1. In the last few turns of the hand wheel, the angle plane at the bottom of the valve stem mechanically wedges against the ball to press it tightly on the valve seat,
 
Complete sealing is achieved.
 
2. when the valve is closed, rotate the hand wheel clockwise, and the valve rod starts to lower and the ball starts to rotate when it leaves the valve seat.
 
3. Continue to rotate the handwheel, and the valve rod is affected by the guide pin embedded in the spiral groove on it, so that the valve rod and the ram rotate 90 ° at the same time.
 
4 the brake body has rotated 90 ° without contact with the valve seat when it is about to close.
 
二.进口闸阀开启程序:
 
1直至到全开位置,阀杆提升到比较限位置,球体旋转到全开位置。
 
2在关闭位置,阀体受阀杆的[wiki]机械[/wiki]施压作用,紧压在阀座上。
 
3当逆时针转动手轮时,阀杆则反向运动,其底部角形平面使球体脱开阀座。
 
4阀杆继续提升,并与阀杆螺旋槽内的导销相互作用,使球体开始无摩擦地旋转。
 
2、 Opening procedure of inlet gate valve:
 
1 until it reaches the full open position, the valve rod is lifted to the limit position, and the ball rotates to the full open position.
 
2 in the closed position, the valve body is pressed on the valve seat by the [wiki] mechanism of the valve stem.
 
3 when the hand wheel is turned counterclockwise, the valve rod moves in reverse direction, and the angle plane at the bottom of the valve rod makes the ball free from the valve seat.
 
4. The valve rod continues to lift and interacts with the guide pin in the screw groove of the valve rod, so that the ball starts to rotate without friction.
