德國BURKERT兩位兩通氣動球閥,進口BURKERT2655型球閥
德國BURKERT兩位兩通氣動球閥的運動曲線，2為排氣閥的運動曲線。縱坐標代表升程h，橫坐標為曲軸的轉(zhuǎn)角（或時間）。從圖中可以看出氣閥的開啟和關(guān)閉都是比較快的。并且氣閥的開啟速度總是要高于氣閥的關(guān)閉速度，這是因為氣閥的開啟過程是在活塞速度很高的階段進行的，而氣閥的關(guān)閉卻是在活塞已位移到接近止點位置，活塞速度已經(jīng)很低的情況下進行的。氣閥在啟閉過程中，閥片、升程限制器及閥座都將受到交變沖擊載荷作用，很容易造成磨損和破壞。
德國BURKERT兩位兩通氣動球閥關(guān)閉的力以及操縱主閥和導閥的能量可能來自系統(tǒng)介質(zhì)、一個外部能源，或者來自這兩者。當系統(tǒng)壓力開始過一個整定的極限值時，導閥開啟，排放少量介質(zhì)，除去或減少主閥閥瓣的關(guān)閉力而讓系統(tǒng)介質(zhì)迫使主閥開啟；當系統(tǒng)壓力降低以后，導閥關(guān)閉，重新產(chǎn)生關(guān)閉力，或者將開啟力消除，主閥關(guān)閉，按照這樣的開啟和關(guān)閉模式，能夠在閥門開啟之前保持一個大的關(guān)閉力。因此，導式安全閥在運行壓力接近整定壓力的情況下也能保持高度的密封性。
