　精小型气动O型球阀是由引进日本技术制造的301K O型球阀配以63000RA系列精小型角行程气动执行机构组成。它以压缩空气为动力，球杆带动球体回转90度即可实现全开——全闭的动作。阀座形式：T，F，C型。其配套使用的附件有空气过滤减压阀，限位开关，电磁阀。其中空气过滤减压阀的主要作用是：稳定压力、过滤空气中的杂质与水汽。该阀使用一定时间经常出现的故障是漏气。下面简单介绍一下该阀的常见故障及相应的维修方法。　　　　对于气动O型阀的漏气方式，常见的有以下几种：　　　　1．汽缸的上下部漏气，这是由于执行机构与气缸的密封处的密封圈由于其执行机构的频繁活动而没有达到密封的效果。　　　　2．汽缸的排气孔漏气，这是因为汽缸内部的两个活动部件与缸体的密封处的密封圈出现老化现象。　　　　3．汽缸上的电磁阀漏气，可能是由于减压阀中的气压过高。　　　　4．除上面的3种情况以外，还有另外一种情况也可能使汽缸漏气，即汽缸中的弹簧损坏，由于力到不到位造成的，这也可能造成关不到位。

Pneumatic O-way valve leak O-intensive small pneumatic valve is made by the introduction of Japanese technology coupled with 63000RA 301K O type ball valve series of fine small rotary pneumatic actuator components. It is powered by compressed air, driven by ball clubs can achieve full rotation of 90 degrees - all the action closed. Seat in the form: T, F, C-type. Supporting the use of accessories with its air filter regulator, limit switches, solenoid valves. Which air filter regulator's main role is: a stable pressure, filter impurities in the air and water vapor. The valve uses a certain time of failure is often leak. The following outlines the common faults of the valve and the corresponding maintenance methods. For the pneumatic valve leak O-mode, common are the following: 1. Top and bottom of cylinder leakage, which is due to actuator and cylinder seals of the ring because of its frequent activities of implementing agencies did not meet the sealing effect. 2. Cylinder vent leak, because the two moving parts within the cylinder and cylinder sealing ring at the emergence of aging. 3. Solenoid valve on the cylinder leakage, pressure reducing valve may be due to the pressure is too high. 4. In addition to the above three cases, there is another situation may cylinder leak that damaged the cylinder in the spring, not in place due to the resulting force, which may cause off not in place.
