Q611N气动高压球阀是通过气源或者电磁阀来驱动执行机构。由执行机构再控制阀门工作的。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。

       Q611N气动高压球阀的主要特点是本身结构紧凑，远程控制，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。

Q611N气动高压球阀优点：

       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、耐高压。

       3．紧密稳定。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。

气动高压球阀

气动高压球阀是一种以压缩空气为动力源的高压控制阀门，通过气动执行器驱动阀杆，带动球体旋转90°实现介质的快速通断，广泛应用于需要远程控制或自动化操作的高压管道系统中。

气动高压球阀主要由球体、阀座、高压阀体、气动执行器（含气缸、活塞、复位弹簧等）及控制附件（如电磁阀、定位器）等组成。其工作原理为：当压缩空气进入执行器一侧气腔时，推动活塞带动阀杆转动，使球体通道与管道对齐（全开）或垂直（全关）；通过切换气源方向，可实现阀门的反向动作，部分型号配备弹簧复位功能，确保断气时阀门自动回到预设状态（全开或全关），提升系统安全性。

气动高压球阀核心优势包括：1. 自动化程度高，可通过控制系统实现远程操作，响应迅速（启闭时间通常在几秒内），适用于连续生产或无人值守场景；2. 耐受高压性能好，公称压力一般可达31.5MPa以上，部分产品可满足超高压工况（如63MPa）；3. 密封稳定，采用金属硬密封或增强聚四氟乙烯等材料，适配温度范围广（-40℃~350℃），可用于油气、蒸汽、腐蚀性流体等多种介质；4. 结构紧凑，维护简便，气动执行器与阀体的集成设计减少了安装空间，且故障率低。

气动高压球阀在应用领域上，气动高压球阀常见于石油化工、天然气输送、电力（如锅炉蒸汽系统）、冶金及高压液压自动化生产线等，尤其适用于高压环境下需要快速、稳定控制介质通断的场景。

Product Overview of Pneumatic High-Pressure Ball Valve

The pneumatic high-pressure ball valve is a type of high-pressure control valve powered by compressed air. It drives the valve stem through a pneumatic actuator, causing the ball to rotate 90° to achieve rapid on-off of the medium, is widely used in high-pressure pipeline systems requiring remote control automated operation.

The valve mainly consists of components such as a ball, valve seat, high-pressure valve body, pneumatic actuator (including cylinder, piston, return spring, etc.), control accessories (such as solenoid valve, positioner). Its working principle is as follows: when compressed air enters the air chamber on one side of the actuator, it pushes the piston to drive the valve stem to rotate, aligning the ball's channel with the pipeline (fully open) making it perpendicular (fully closed); by switching the direction of the air source, the reverse action of the valve can be realized. Some models are equipped with a spring return function to ensure that the valve automatically returns to a preset state (fully open closed) when the air supply is cut off, improving system safety.

Its core advantages include: 1. High degree of automation, enabling remote operation through the control system with rapid response (opening closing time is usually within a few seconds), suitable for continuous production unattended scenarios; 2. Excellent high-pressure resistance, with a nominal pressure generally reaching 31.5MPa higher, some products can meet ultra-high pressure working conditions (e.g., 63MPa); 3. Reliable sealing, using metal hard seals reinforced polytetrafluoroethylene other materials, with a wide applicable temperature range (-40℃~350℃), applicable to various media such as oil gas, steam, corrosive fluids; 4. Compact structure easy maintenance; the integrated design of the pneumatic actuator valve body reduces installation space has a low failure rate.

In terms of application fields, pneumatic high-pressure ball valves are commonly used in petrochemicals, natural gas transmission, power generation (e.g., boiler steam systems), metallurgy, high-pressure hydraulic automated production lines, especially suitable for scenarios requiring rapid stable control of medium on-off in high-pressure environments.
