BKH高压球阀它具有旋转90度的动作，旋塞体为球体，有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀适宜做开关、切断阀使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用，如V型球阀。

      BKH高压球阀正常连接方式有内螺纹式 卡套式和活接焊接式三种连接方式。BKH高压球阀本身结构紧凑，密封稳定，结构简单，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等，在各行业得到广泛的应用。球阀阀体可以是整体的，也可以是组合式的。

BKH高压球阀优点：

      1．流体阻力小，全通径的球阀基本没有流阻。

      2．结构简单、体积小、重量轻。

      3．紧密度好。它有两个密封面，而且目前球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。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。

      8．由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。

Here is an introduction to BKH high-pressure ball valves:

Structure Principle

- Structural Composition: Mainly composed of components such as the ball, valve seat, sealing ring, valve stem.

- Working Principle: It controls the circulation cutoff of media through the rotation of the ball. When the valve is closed, the ball forms a seal with the valve seat via the valve seat sealing ring to prevent leakage; when opened, the medium flows through the ball's channel.

 Features- Excellent Sealing Performance: Adopts an all-metal structure a sealing structure between the ball the valve seat. For example, the sealing surface uses materials like polytetrafluoroethylene (PTFE), which is resistant to high pressure, high temperature, strong corrosion, effectively preventing medium leakage.

- Wear Resistance: The sealing surface is made of wear-resistant materials such as tungsten-molybdenum alloy, allowing for long-term use without easy wear.

- Easy Operation: Can be equipped with manual operating devices electric/pneumatic actuators, featuring simple operation quick opening closing.

- High Safety: Adopts advanced fire explosion prevention measures to ensure production safety.
