燃?xì)饩o急切斷閥的產(chǎn)品特點(diǎn)介紹，澆封防爆：根本杜絕火花產(chǎn)生，更加穩(wěn)定可靠。開(kāi)閥方式：手動(dòng)復(fù)位，避免事故發(fā)生。保持方式：能在開(kāi)閥與關(guān)閥狀態(tài)下穩(wěn)定工作即雙穩(wěn)態(tài)。關(guān)閥速度：0.5秒之內(nèi)可切斷氣源。強(qiáng)震關(guān)閥：在強(qiáng)烈震動(dòng)情況下，閥門(mén)可自行關(guān)閉。密封形式：采用三級(jí)密封形式。外置鐵芯：鐵芯置于氣體環(huán)境外，能有效避免雜質(zhì)吸附使密封失效。鍛造閥體：能承受大扭矩而閥體不開(kāi)裂。密封特點(diǎn)：壓力越大密封越緊，可保閥門(mén)多工況下穩(wěn)定工作。動(dòng)作可靠：可保持10年以上有效動(dòng)作。</p><p
