YA40Y帶散熱器彈簧全啟式安全閥適用于工作溫度≤450℃的空氣、水、氮氫混合氣等介質(zhì)的設(shè)備或管路上,YA40Y-P適用于工作溫度≤300℃有腐蝕性介質(zhì)的設(shè)備或管路上,作為超壓保護裝置。
產(chǎn)品工作原理和用途:
YA40Y帶散熱器彈簧全啟式安全閥適用于工作溫度≤450℃的空氣、水、氮氫混合氣等介質(zhì)的設(shè)備或管路上,YA40Y-P適用于工作溫度≤300℃有腐蝕性介質(zhì)的設(shè)備或管路上,作為超壓保護裝置。當(dāng)設(shè)備和客路內(nèi)壓力超過允許值時,閥門自動開啟,繼而全量排放;當(dāng)壓力降低至規(guī)定值時,閥門自動關(guān)閉,保證設(shè)備全定運行。
產(chǎn)品結(jié)構(gòu)特點:
1、帶扳手彈簧全啟式安全閥具有結(jié)構(gòu)簡單、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。
2、噴嘴型閥座:閥座為位伐爾噴嘴型閥座,蒸汽流經(jīng)閥座出口處時達到音速,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。
3、熱彈性閥瓣:閥瓣設(shè)計為熱彈性結(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的前泄現(xiàn)象。閥瓣密封面采用先進的激光淬火技術(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,使閥門背壓降低。下調(diào)時,使閥門背壓提高。
