开关无磨损：球体偏离阀座后再转动，xx了与阀座的摩擦，解决了传统球阀、闸阀、旋塞阀阀座的磨损问题。 单阀座设计：轨道球阀的静态单阀座，能保障双向零泄漏，避免了双阀座内腔压力升高的问题。 抗磨硬密封面阀芯：阀芯密封面堆焊了一层硬质合金，并进行抛光，能满足在非常苛刻的介质场合下的密封性。 双阀杆导向销：阀杆导向槽，沿硬性导向销滑动，平稳地控制阀杆的升降和转动。 机械楔紧力：阀杆下端的凸轮斜面，可提供一个机械楔紧力，以保证阀芯与阀座件持续的贴紧力。 上装式设计：在系统卸压后，可在线进行检查和维修，使维护简单化。 内漏检测：阀体上设计有特殊装置，可在线检测阀门内漏。 低扭矩操作：因轨道球阀密封面无摩擦，转动扭矩小，除特大尺寸需齿轮向外，均可配小齿轮。 {zj0}流动特性：全通径和标准通径都有很高的Cv值，降低了管线的沿程阻力损失，使磨损问题降低到{zd1}限度。 自清洗：当阀芯偏离阀座时，介质可沿密封面360度流动，将介质中的杂质冲洗干净。 可注入密封脂：在运行中可进行维护，将密封脂通过注脂器注入，xx控制会阀，防止泄漏。 长寿命：轨道球阀可替代那些密封副易出故障的普通球阀、闸阀、截止阀、旋塞阀。轨道球阀独有的特性，能有效减少装置故障率，大大地降低用户的使用、维修成本。

原文：
Switch no wear: ball valve seat and then deviate from the rotation, eliminating the friction with the valve seat, to solve the traditional ball valve, gate valve, plug valve seat wear problems. Single-seat design: the static single-track valve seat, can protect the bi-directional zero leakage, to avoid the double seat cavity pressure increases the problem. Wear a hard sealing surface spool: spool sealing surface, a layer of hard alloy welding and polishing, to meet the media in a very demanding sealing occasions. Double stem-oriented marketing: stem guide slot, sliding along the rigid guide pin, smooth movements and rotational control of the valve stem. Mechanical wedge clamping force: the stem at the bottom of the cam slope, providing a mechanical wedge clamping force to ensure the valve core and valve seat closely aligns pieces of sustained power. Upload design: After unloading in the system, available online for inspection and maintenance, to maintain simplicity. Endoleak detection: there are special devices on the body can be in-line detection of valve leakage. Low torque operation: track ball valve sealing surface due to friction, rotation torque is small, except large size necessary gear out, can be equipped with a small gear. The best flow characteristics: full bore and have a very high standard Path Cv value, reducing the pressure loss along the pipeline, so to minimize wear and tear issues. Self-cleaning: When the valve seat when the deviation from the medium can flow along the sealing surface of 360 degrees, to clean the impurities in the medium. Can be injected into sealing grease: the operation can be maintained, the grease through the grease seal injection, will fully control valve to prevent leakage. Long life: Track ball can easily replace those Sealing the fault of the ordinary ball valves, gate valves, globe valves, plug valves. Unique characteristics of track ball, can effectively reduce the device failure rate, greatly reducing the user cost of maintenance.
