上球气动球阀是球阀配上气动执行器。气动执行器的执行速度相对较快，*快的开关速度0.05秒/次，所以通常也叫气动快速切断球阀。气动球阀通常配置各种附件，比如电磁阀、气源处理三联件、限位开关、定位器、控制箱等，以实现就地控制和远距离集中控制，在控制室里就可以控制阀门的开关，不需要跑到现场或者高空和危险地带来手动控制，在很大程度上节约了人力资源以及时间和安全性。气动球阀具体分类有：不锈钢气动球阀，塑料气动球阀，卫生级气动球阀，碳钢气动球阀，二通气动球阀，三通气动球阀，四通气动球阀。
气动球阀是由旋塞阀演变而来。它具有相同的旋转90度动作，不同的是旋塞体是球体，有圆形通孔或通道通过其轴线。球面和通道口的比例应该是这样的，即当球旋转90度时，在进、出口处应全部呈现球面，从而截断流动。 本类阀门在管道中可任意位置安装。气动球阀，不锈钢气动球阀，温州气动球阀生产商，气动球阀，不锈钢气动球阀。
气动球阀只需要用气动执行器用气源旋转90度的操作和很小的转动力矩就能关闭严密。完全平等的阀体内腔为介质提供了阻力很小、直通的流道。通常认为球阀*适宜直接做开闭使用，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。球阀的主要特点是本身结构紧凑，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。球阀阀体可以是整体的，也可以是组合式的。
气动球阀与其它阀类相比的具有以下优点： 标准气动球阀结构图
A、防静电功能：在球体、阀杆、阀体之间设置弹簧，能将开关过程产生的静电导出。执行机构；
B、阀杆密封可靠，由于阀杆只作彷转动运而不做升降运动，阀杆的填料密封不易破坏，且密封能力随着介质的压力增高而增大；
C、阀座密封性能好，采用聚四氟乙烯等弹性材料制成的密封圈，结构易于密封，而且球阀的阀封能力随着介质压力的增高而增大；
D、止推轴承减小阀杆磨擦力矩，可使阀杆长期操作平稳灵活；
E、由于聚四氟乙烯等材料具有良好的自润滑性，与球体的磨擦损失小，故球阀的使用寿命长；
F、下装式阀杆和阀杆头部凸阶防止阀杆喷出，如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封；
G、流体阻力小、球阀是所有阀类中流体阻力*小的一种，即使是缩径球阀，其流体阻力也相当小。气动球阀主要用于截断或接通管路中的介质，亦可用用于流体的调节与控制,在如上几个方面与同类阀类相比之下，优点突出！气动球阀，不锈钢气动球阀，温州气动球阀生产商，气动球阀，不锈钢气动球阀，温州气动球阀生产商，气动球阀，不锈钢气动球阀，温州气动球阀生产商。

Product details:
On the ball pneumatic ball valve ball valve coupled with pneumatic actuator. The execution speed of pneumatic actuators is relatively fast, the fastest switching speed of 0.05 seconds / times, it is usually also called pneumatic quick to cut off the ball valve. Pneumatic ball valve is usually equipped with various accessories such as solenoid valves, air FRL limit switches, positioners, control boxes, etc., in order to achieve local control and remote centralized control, the control room can control valve door switch, do not need to went to the scene or at high altitudes and danger brought about manual control, in large part to save human resources and time and security. Pneumatic ball classifications are: stainless steel pneumatic valve, plastic pneumatic valve, Sanitary pneumatic valve, pneumatic ball valves carbon steel, two-way pneumatic valve, three-way pneumatic ball valve, four-way pneumatic ball.
Pneumatic ball valves are evolved from the stopcock. It has the same rotation of 90 degrees of movement, different cocks body is a sphere, a circular through-hole or channel through its axis. Sphere and the ratio should be such, that is when the ball spins 90 degrees, into the exit should be fully rendered sphere, thus cutting off the flow. The valve in the pipe can be installed anywhere.
Pneumatic valve only need pneumatic actuators used in gas source rotated 90 degrees to operate and a small torque can be closed tightly. Full equality of the body cavity of the media to provide a little resistance, through the flow channel. Usually considered the most suitable valve directly to do the opening and closing to use, but recent developments have ball valve is designed to give it throttle and control the flow. The main features of valve is its own compact, easy operation and maintenance, and for general working media such as water, solvent, acid and gas, but also for the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene . Ball valve can be a whole, can also be combined.
Pneumatic ball valves and other valves has the following advantages: standard pneumatic valve structure diagram
A, anti-static function: set between ball, stem, valve springs, the static electricity generated by the switching process can be export. Actuators;
Stem seal and reliable, due to the stem only for imitation rotation transported without doing the lifting movement, the valve stem packing seal not easily damaged, and the sealing capacity along with increased media pressure increase;
Seat sealing performance is good, made of elastic material such as PTFE sealing ring, the structure easy to seal, and the valve seal ball valve capacity is increasing with the increase of medium pressure;
D and thrust bearings to reduce stem friction torque, can stem the long-term stable operation and flexible;
E, due to the Teflon and other materials have good self-lubrication, and the sphere of friction loss is small, the ball valve of the long service life;
F, downloading the stem and the stem head convex order to prevent the stem spray, such as fires caused by the stem seal damage, the convex order and the body can form metal contacts to ensure the stem seal;
Fluid resistance is small, ball valves all valves in the fluid path of least resistance, even reduced bore ball valve, the fluid resistance is quite small. Pneumatic ball is mainly used for the media in truncated or connected piping can also be used for the regulation and control of the fluid, and contrast with similar valves in the above aspects highlight the advantages!
