气动O型球阀

产品特点

 1、O型固定式球阀采用固定球设计，相对运动部位均采用摩擦系数极小自润滑材料，因而操作扭矩小，此外密封润滑脂的长期密封，使得操作更加灵活。                                                                                                                                

 2、阀门采用高平台结构，ISO5211连标准，能使安装电/气动执行器更为专业化。                                                                                                                                                                                               

 3、O型固定式球阀采用全通径或缩径设计，流通阻力小。                                                                                                                                                                                                                     

 4、金属硬密封O型固定式球阀采用双向金属可动密封结构，具有自动补偿功能，密封性能优越。                                                                                                                                                                                   

 5、O型固定式球阀采用固定球设计，并增加了预紧力弹簧，使得球阀具有自动泄压功能。                                                                                                                                                                                         

 6、每个球阀都有两个可动密封座，两个方向都能密封，因而安装时不须考虑介质的流向。                                                                                                                                                                                        

 7、具有防火防静电结构，在阀杆与阀体及阀杆与球体之间设置导电弹簧，避免静点打火点燃易燃介质。确保系统安全。                                                                                                                                                              

 8、耐火结构双重保护，但万一发生火灾而使密封圈烧损时，球阀的各个部位均能形成金属对金属的硬密封结构。                                                                                                                                                                    

 9、自动泄压结构，当滞留在阀门中腔的液体介质由于温度升高而气化，从而中腔压力异常升高时，中腔介质能依靠本身的推力推动阀座而自动泄压，从而确保阀门安全。

10、可选气动、电动、液动、及气动调节型、电动调节型。
