高压阀门解析球阀和蝶阀的区别

发布时间:2017-06-02 14:15:56   发布人:http://xacrystaledu.com
球阀和蝶阀都是对比常用的阀门。有些场合是能够通用的,有些只能用其中的一种。两者的差异首要在于构造和开关原理。高压阀门厂家给出了简要分析:
Ball and butterfly valves are commonly used valves. Some situations are universal, some can only be used one of them. The main difference between the two is the principle of construction and switching. High pressure valve manufacturers provide a brief analysis:
一、球阀:旋塞阀演变而来,启闭件是球体。
Ball valves: the cocks are evolving and the opening is a sphere.
特点是:
Features are:
1.流体阻力小,全通径的球阀根本没有流阻。
The fluid resistance is small, and the full size ball valve has no resistance at all.
2.构造简略、体积小、重量轻。
The structure is brief, small and lightweight.
3.紧密牢靠。它有两个密封面,并且现在球阀的密封面资料广泛运用各种塑料,密封性好,能完成彻底密封。在真空体系中也已广泛运用。
Be strong. It has two sealing covers, and now the seal of the ball valve is widely used in various kinds of plastic, the sealing is good, can complete the complete seal. It is also widely used in vacuum systems.
4.操作便利,开闭敏捷,从全开到全关只要旋转90°,便于远距离的操控。
4. The operation is convenient, quick opening and closing, from open to close just rotate 90 °, to facilitate remote manipulation.
5.修理便利,球阀构造简略,密封圈通常都是活动的,拆开替换都对比便利。
Repair convenience, ball valve construction is brief, sealing ring is usually active, and the replacement is convenient.
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腐蚀。
When full or closed, the sealing of the ball and seat is isolated from the medium and the medium is not corroded by the sealing surface of the valve.
7.适用规模广,通径从小到几毫米,大到几米,从高真空至高压力都可使用。

The scale is wide, from small to a few millimeters, large to several meters, from high vacuum to high pressure.
8.因为球阀在启闭过程中有擦洗性,所以可用于带悬浮固体颗粒的介质中。
Because the ball valve is scrubbed during the open and closed process, it can be used in the medium with suspended solid particles.
二、蝶阀:启闭件是圆盘式摆布敞开。特点:
Butterfly valves: open and closed are round and open. Features:
1、构造简略、体积小、装置便利;
1, the construction is brief, the volume is small, the device is convenient;
2、流阻系数小,启闭敏捷;
The resistance coefficient is small and the speed is fast.
3、可用于大口径阀门;
Can be used in large-caliber valves;
4、可使用不一样的密封面,运用各种环境,包括粉状、颗粒状介质;
Use a different sealing surface, use various kinds of environment, including powder, granular medium;
5、启闭便利敏捷、省力、流体阻力小,能够常常操作。
5, open and close convenient agile, energy-saving, fluid resistance is small, can operate often.
6、能够运送泥浆,在管道口积存液体起码。
Able to carry mud and deposit liquid at the pipe.
7、低压下,能够完成杰出的密封。
Under low pressure, excellent sealing can be achieved.
8、调理性能好。
Good conditioning.
