■產(chǎn)品簡(jiǎn)介: | 1、彈簧全啟式安全閥具有結(jié)構(gòu)簡(jiǎn)單、密封性能好、開啟壓力準(zhǔn)確、排放能力大、回座壓差小、調(diào)整方便等特點(diǎn)。 2、噴嘴型閥座:閥座為位伐爾噴嘴型閥座,蒸汽流經(jīng)閥座出口處時(shí)達(dá)到音速,排放系數(shù)大,閥座密封面堆焊鈷鉻鎢硬質(zhì)合金,耐磨抗沖蝕,壽命長(zhǎng)。 3、熱彈性閥瓣:閥瓣設(shè)計(jì)為熱彈性結(jié)構(gòu),利用其在介質(zhì)壓力下微小的變形,提高密封能力,克服安全閥在介質(zhì)壓力下臨近整定壓力時(shí)的前泄現(xiàn)象。閥瓣密封面采用的激光淬火技術(shù),提高了硬度、耐磨性、抗沖抗性。 4、調(diào)節(jié)螺母:通過調(diào)整調(diào)節(jié)螺母,調(diào)整彈簧壓縮量,使閥門能夠很方便、很迅速地獲得準(zhǔn)確的整定壓力。 5、背壓調(diào)整套:調(diào)整閥瓣背壓的輔助機(jī)構(gòu),通過背壓調(diào)整套調(diào)整,可獲得合適的回座壓差。上調(diào)時(shí),使閥門背壓降低。下調(diào)時(shí),使閥門背壓提高。 | ■安裝說明: | 1、安全閥必須垂直:安裝,并直接安裝在容器或管道的接頭上。接頭內(nèi)徑應(yīng)不小于安全閥的進(jìn)口通徑。 2、安全閥的出口必須裝設(shè)適當(dāng)?shù)呐蛎浌?jié),以防止排放管的熱膨脹給安全閥帶來不應(yīng)有的熱應(yīng)力。排放管內(nèi)徑應(yīng)比閥門出口直徑大,長(zhǎng)度盡可能短,避免拐彎。排放管及膨脹節(jié)重量不應(yīng)作用在安全閥上,應(yīng)固定在建筑上。排放管的中心線與閥體的中心線間距離盡可能的短。對(duì)每臺(tái)安全閥都應(yīng)單獨(dú)裝設(shè)排放管。 3、消聲器的出口處要有足夠的面積,防止產(chǎn)生背壓影響閥門的排放能力。 | ■主要零件材料: | NO. | 零件名稱 | A42Y-C/KA42Y-C材料 | A42Y-P/KA42Y-P材料 | A42Y-R材料 | DA42Y-P材料 | 1 | 閥座 | 2Cr13/1Cr18Ni9Ti | ZG1Cr18Ni9Ti | ZG1Cr18Ni12Mo2Ti |
