氣動O型球閥

產(chǎn)品特點(diǎn)

 1、O型固定式球閥采用固定球設(shè)計，相對運(yùn)動部位均采用摩擦系數(shù)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(jié)構(gòu)，ISO5211連標(biāo)準(zhǔn)，能使安裝電/氣動執(zhí)行器更為專業(yè)化。                                                                                                                                                                                               

 3、O型固定式球閥采用全通徑或縮徑設(shè)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(jié)構(gòu)，具有自動補(bǔ)償功能，密封性能優(yōu)越。                                                                                                                                                                                   

 5、O型固定式球閥采用固定球設(shè)計，并增加了預(yù)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(zhì)的流向。                                                                                                                                                                                        

 7、具有防火防靜電結(jié)構(gòu)，在閥桿與閥體及閥桿與球體之間設(shè)置導(dǎo)電彈簧，避免靜點(diǎn)打火點(diǎn)燃易燃介質(zhì)。確保系統(tǒng)安全。                                                                                                                                                              

 8、耐火結(jié)構(gòu)雙重保護(hù)，但萬一發(fā)生火災(zāi)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(jié)構(gòu)。                                                                                                                                                                    

 9、自動泄壓結(jié)構(gòu)，當(dāng)滯留在閥門中腔的液體介質(zhì)由于溫度升高而氣化，從而中腔壓力異常升高時，中腔介質(zhì)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(diào)節(jié)型、電動調(diào)節(jié)型。
