闸阀的优点

Advantages of Gate Valves

　　1、闸阀的流动阻力小。阀体内部介质通道是直通的，介质成直线流动，流动阻力小。

1. The flow resistance of gate valves is small. The medium channel inside the valve body is straight, and the medium flows in a straight line with low flow resistance.

　　2、闸阀启闭时较省力。是与截止阀相比而言，因为无论是开或闭，闸板运动方向均与介质流动方向相垂直。

2. The gate valve is more effortless to open and close. Compared to globe valves, the direction of gate movement is perpendicular to the direction of medium flow, whether it is open or closed.

　　3、高度大，启闭时间长。闸板的启闭行程较大，降是通过螺杆进行的。

3. High height, long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lowering is carried out through the screw.

　　4、水锤现象不易产生。原因是关闭时间长。

4. The phenomenon of water hammer is not easy to occur. The reason is that the shutdown time is long.

　　5、介质可向两侧任意方向流动，易于安装。闸阀通道两侧是对称的。

5. The medium can flow in any direction on both sides, making it easy to install. The two sides of the gate valve channel are symmetrical.

　　6、结构长度(系壳体两连接端面之间的距离)较小。

6. The structural length (the distance between the two connecting end faces of the shell) is relatively small.

　　7、形体简单，结构长度短，制造工艺性好，适用范围广。

7. Simple shape, short structural length, good manufacturing process, and wide applicability.

　　8、结构紧凑，阀门刚性好，通道流畅，流阻数小，密封面采用不锈钢和硬质合金，使用寿命长，采用PTFE填料.密封可靠.操作轻便灵活.

8. Compact structure, good valve rigidity, smooth channel, low flow resistance, sealing surface made of stainless steel and hard alloy, long service life, using PTFE packing. Reliable sealing, easy and flexible operation
