Q24N外螺纹直角球阀它具有旋转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。

Q24N外螺纹直角球阀的进出口都是外螺纹连接，进口和出口呈90度。适合角式管道作起闭用。主要特点是本身结构紧凑，密封稳定，外形精巧，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。

       Q24N外螺纹直角球阀优点：

       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。

外螺纹直角球阀

外螺纹直角球阀是外螺纹球阀的一种，是通过外螺纹与管道连接，通道呈直角形状的流体控制阀门 。以下是其产品概述：

外螺纹直角球阀- 结构特点：主要由阀体、球体、阀杆、阀座等部件组成。阀体一般采用不锈钢、黄铜等金属材料，具有良好的强度和耐腐蚀性。螺纹规格通常为NPT（美制锥管螺纹）、BSP（英制管螺纹）等，能与相应管道螺纹紧密配合。阀座多采用软密封或硬密封设计，以满足不同密封要求。直角形状的阀体可使管路在需要改变流向的地方实现紧凑连接。

外螺纹直角球阀- 工作原理 ：通过旋转阀杆带动球体转动，当球体上的通孔与管道通道相对应时，介质可流通；当球体旋转90°，通孔与管道通道错开时，阀门关闭，截断介质流动。

外螺纹直角球阀- 性能优势 ：流体阻力小，阻力系数与同长度管段相等；结构简单、体积小、重量轻；密封性能好，密封面材料常为塑料，在真空系统中也可使用；操作方便，开闭迅速，从全开到全关只需旋转90°，且便于远距离控制；维修方便，密封圈一般为活动式，拆卸更换容易；在全开或全闭时，球体和阀座的密封面与介质隔离，不易被介质侵蚀；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。

外螺纹直角球阀- 应用领域：适用于水、油、气、蒸汽等多种介质的管道系统。广泛应用于化工、石油、电力、冶金、船舶、民用水暖等行业，可用于截断或接通管路中的介质，也可用于分配介质与改变介质的流向 。

The external - thread right - angle ball valve is a type of external - thread ball valve. It is a fluid - control valve that is connected to the pipeline through external threads, its channel is in a right - angle shape. The product overview is as follows:

- Structural features: It is mainly composed of components such as the valve body, ball, valve stem, valve seat. The valve body is generally made of metal materials such as stainless steel brass, which have good strength corrosion resistance. The thread specifications are usually NPT (National Pipe Taper) BSP (British Standard Pipe), which can be closely matched with the corresponding pipeline threads. The valve seat mostly adopts soft - seal hard - seal design to meet different sealing requirements. The right - angle - shaped valve body can realize a compact connection in the place the pipeline needs to change the flow direction.

- Working principle: The ball is driven to rotate by turning the valve stem. When the through - hole on the ball corresponds to the pipeline channel, the medium can flow. When the ball rotates 90°, the through - hole is staggered the pipeline channel, the valve is closed to cut off the flow of the medium.

- Performance advantages: The fluid resistance is small, the resistance coefficient is equal to that of the pipe section with the same length. It has a simple structure, small volume, light weight. The sealing performance is good. The sealing surface material is usually plastic, it can also be used in the vacuum system. It is easy to operate, the opening closing are rapid. It only needs to rotate 90° full - open to full - closed, it is convenient for remote control. It is convenient for maintenance, the sealing ring is generally movable, which is easy to disassemble replace. When it is fully open fully closed, the sealing surface of the ball the valve seat is isolated the medium, it is easy to be eroded by the medium. It has a wide range of applications, with a diameter ranging a few millimeters to several meters, it can be applied high - vacuum to high - pressure.

- Application fields: It is suitable for pipeline systems of various media such as water, oil, gas, steam. It is widely used in industries such as chemical engineering, petroleum, electric power, metallurgy, shipbuilding, civil water - heating. It can be used to cut off connect the medium in the pipeline, can also be used to distribute the medium change the flow direction of the medium.
