进口锻钢球阀结构特点
 
1、流体阻力小,其阻力系数与同长度的管段相等。
2、结构简单、体积小、重量轻。
3、紧密可靠,现球阀的密封面材料广泛使用塑料、密封性好,在真空系统中也已广泛使用。
4、操作方便,开闭迅速,从全开到全关只要旋转90°,便于远距离的控制。
5、维修方便,球阀结构简单,密封圈一般都是活动的,拆卸更换都比较方便。
6、在全开或全闭时,球体和阀座的密封面与介质隔离,介质通过时,不会引起阀门密封面的侵蚀。
7、适用范围广,通径从小到几毫米,大到几米,从高真空至高压力都可应用。 球旋转90度时,在进、出口处应全部呈现球面,从而截断流动。


Structural features of imported forged steel ball valve:
 
1. The resistance coefficient of the fluid is equal to that of the same length of pipe segment.
 
2. Simple structure, small volume and light weight.
 
3. It is compact and reliable. Now, the sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum system.
 
4. It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
 
5. Maintenance is convenient, ball valve structure is simple, sealing ring is generally movable, disassembly and replacement are more convenient.
 
6. When the valve is fully open or closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, the valve sealing surface will not be eroded.
 
7. It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the inlet and outlet, so as to cut off the flow.
