四、Warranty 气动三通烟气阀技术协议书 保修

本实用新型公开了一种有机废气净化处理回收设备气动三通阀，它涉及有机废气净化领域，它包含气缸、气缸接座、上端盖、上阀体法兰、进气接口、上阀体、拉杆、半对开环、密封圈、进出气接口、中阀体、排气孔、中阀体连接法兰、阀板和下阀体；它结构设计合理，造型新颖*，操作简单，使用方便，法兰和阀座之间采用整体成型的方式降低了设备的加工难度、加工量和焊接难度、焊接量，也可降低阀座在阀体上焊接后产生变形，气缸拉杆下部半圆形连接头卧在连接法兰上的半圆形凹槽内，由半对开环与连接法兰固定，使拉杆的半圆头镶嵌在阀板上，从而阀板可以小幅度上下旋转一定角度，使阀板能更有效、更稳妥的压在密封圈上。由于这种阀门的工作环境处于经常处于高温烟气中，因此业内也常称之为高温烟气三通阀。目前，现有的高温三通阀包括阀体、阀杆、螺杆、螺母；安装后，阀杆的下端伸入阀体内，阀杆的上端和螺杆的下端通过销轴连接起来，螺杆的中部安装有螺母，螺母安装于轴承座内且螺母的上端部分伸出轴承座；螺母旋转时，带动螺杆做直线运动，进而通过阀杆带动阀体的阀瓣完成阀门的操作。但是现有的这种阀门，阀体受到高温烟气的热传导作用，而由于螺杆的一部分还是伸入到阀体内，因此阀体将热量传递给螺杆，进而传递给螺母，这造成螺杆、螺母之间润滑脂的不断挥发，不断增大螺杆、螺母之间的运动阻力，影响阀门的正常工作运行。 Regarding the guarantee issue please see the Commercial Contract.关于保修条款见商务合同。
①齿轮齿条双活塞对称结构设计，动作快速平稳，精度高，输出功率大，通过简单的改变活塞装配位置可得到反方向旋转。
②挤压的铝合金缸体，经精密加工的内孔和外部表面进行硬质阳极氧化处理（特殊情况下阳极氧化+特氟隆涂层），使用寿命更长，摩擦系数低。
③一体式设计，所有的双作用和单作用执行器型号，都具有相同的缸体和端盖，很方便通过加装弹簧或拆除弹簧来改变作用方式。
④组合式预符荷安全弹簧组，不论在装配过程或使用现场中，都能方便而安全的安装或增减弹簧数量。
⑤外部侧面两个单独调节螺钉对于已安装在阀门上的执行器更是方便，调节阀开和阀关位置，如需全行程调节时则另外在两个端盖处配置较长调节螺钉。
⑥多功能位置指示器，现场可视化指示，符合VID/VIE3845、NAMUR标准槽，能安装并输出所有附件，如限位开关盒、电气定位器、位置传感器（倍加福、图尔克）。
⑦气源接口符合NRMAR标准，可直接安装NUMAR标准电磁阀。
⑧齿条背面的复合材料轴瓦和活塞导向环以及输出轴的轴承等为防止金属对金属的摩擦，并且增加润滑,使其低摩擦、长寿命。
⑨所有的紧固件均采用不锈钢材料，抗腐蚀。
⑩连接部分符合全新标准规范ISO5211，DIN3337（F03-F25）使产安装具有互换性、通用性。
