德國BURKERT兩位兩通氣動球閥,進(jìn)口BURKERT2655型球閥
簡要描述:

德國BURKERT兩位兩通氣動球閥,進(jìn)口BURKERT2655型球閥
德國BURKERT兩位兩通氣動球閥關(guān)閉的力以及操縱主閥和導(dǎo)閥的能量可能來自系統(tǒng)介質(zhì)、一個(gè)外部能源,或者來自這兩者。當(dāng)系統(tǒng)壓力開始過一個(gè)整定的極限值時(shí),導(dǎo)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;

德國BURKERT兩位兩通氣動球閥,進(jìn)口BURKERT2655型球閥
德國BURKERT兩位兩通氣動球閥的運(yùn)動曲線,2為排氣閥的運(yùn)動曲線?v坐標(biāo)代表升程h,橫坐標(biāo)為曲軸的轉(zhuǎn)角(或時(shí)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?yàn)闅忾y的開啟過程是在活塞速度很高的階段進(jìn)行的,而氣閥的關(guān)閉卻是在活塞已位移到接近止點(diǎn)位置,活塞速度已經(jīng)很低的情況下進(jìn)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(dǎo)閥的能量可能來自系統(tǒng)介質(zhì)、一個(gè)外部能源,或者來自這兩者。當(dāng)系統(tǒng)壓力開始過一個(gè)整定的極限值時(shí),導(dǎo)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(dāng)系統(tǒng)壓力降低以后,導(dǎo)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(gè)大的關(guān)閉力。因此,導(dǎo)式安全閥在運(yùn)行壓力接近整定壓力的情況下也能保持高度的密封性。
