氣動O型球閥

產品特點

 1、O型固定式球閥采用固定球設計，相對運動部位均采用摩擦系數極小自潤滑材料，因而操作扭矩小，此外密封潤滑脂的長期密封，使得操作更加靈活。                                                                                                                                

 2、閥門采用高平臺結構，ISO5211連標準，能使安裝電/氣動執行器更為專業化。                                                                                                                                                                                               

 3、O型固定式球閥采用全通徑或縮徑設計，流通阻力小。                                                                                                                                                                                                                     

 4、金屬硬密封O型固定式球閥采用雙向金屬可動密封結構，具有自動補償功能，密封性能優越。                                                                                                                                                                                   

 5、O型固定式球閥采用固定球設計，并增加了預緊力彈簧，使得球閥具有自動泄壓功能。                                                                                                                                                                                         

 6、每個球閥都有兩個可動密封座，兩個方向都能密封，因而安裝時不須考慮介質的流向。                                                                                                                                                                                        

 7、具有防火防靜電結構，在閥桿與閥體及閥桿與球體之間設置導電彈簧，避免靜點打火點燃易燃介質。確保系統安全。                                                                                                                                                              

 8、耐火結構雙重保護，但萬一發生火災而使密封圈燒損時，球閥的各個部位均能形成金屬對金屬的硬密封結構。                                                                                                                                                                    

 9、自動泄壓結構，當滯留在閥門中腔的液體介質由于溫度升高而氣化，從而中腔壓力異常升高時，中腔介質能依靠本身的推力推動閥座而自動泄壓，從而確保閥門安全。

10、可選氣動、電動、液動、及氣動調節型、電動調節型。
