BURKERT寶帝2702型氣動(dòng)調(diào)節(jié)閥/BURKERT調(diào)節(jié)閥
BURKERT寶帝2702型氣動(dòng)調(diào)節(jié)閥是采用控制閥體內(nèi)的啟閉件的開(kāi)度來(lái)調(diào)節(jié)介質(zhì)的流量，將介質(zhì)的壓力降低，同時(shí)借助閥后壓力的作用調(diào)節(jié)啟閉件的開(kāi)度，使閥后壓力保持在一定范圍內(nèi)，并在閥體內(nèi)或閥后噴入冷卻水，將介質(zhì)的溫度降低，這種閥門(mén)稱(chēng)為減壓減溫閥。該閥的特點(diǎn)，是在進(jìn)口壓力不斷變化的情況下，保持出口聽(tīng)壓力和溫度值在一定的范圍內(nèi)。減壓閥按結(jié)構(gòu)形式可分為薄膜式、彈簧薄膜式、活塞式、杠桿式和波紋管式；按閥座數(shù)目可人為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式。導(dǎo)式減壓閥當(dāng)減壓閥的輸出壓力較高或通徑較大時(shí)，用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然過(guò)大，流量變化時(shí)，輸出壓力波動(dòng)較大，閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點(diǎn)，可采用導(dǎo)式減壓閥。導(dǎo)式減壓閥的工作原理與直動(dòng)式的基本相同。BURKERT寶帝2702型氣動(dòng)調(diào)節(jié)閥座有的和閥體是一個(gè)整體，有的是和閥體組裝在一起的，它與設(shè)備連通。閥瓣常連帶有閥桿，它緊扣在閥座上。閥瓣上面是加載機(jī)構(gòu)，載荷的大小可以調(diào)節(jié)。當(dāng)設(shè)備內(nèi)的壓力在一定的工作壓力范圍之內(nèi)時(shí)，內(nèi)部介質(zhì)作用于閥瓣上面的力小于加載機(jī)構(gòu)加在閥上面的力，兩者之差構(gòu)成閥瓣與閥座之間的密封力，使閥瓣緊壓著閥座，設(shè)備的介質(zhì)無(wú)法排出。當(dāng)設(shè)備內(nèi)的壓力超過(guò)規(guī)定的工作壓力并達(dá)到安全閥的開(kāi)啟壓力時(shí)，內(nèi)部介質(zhì)作用于鬧瓣上面的力大于加載機(jī)構(gòu)施加在它上面的力，于是閥瓣離開(kāi)閥座，安全閥開(kāi)啟，設(shè)備內(nèi)的介質(zhì)即通過(guò)閥座排出、如果安全閥的排量大于設(shè)備的安全泄放量，設(shè)備內(nèi)壓力即逐漸下降，而且通過(guò)短時(shí)間的排氣后，壓力即降回正常工作壓力。
