A40Y帶散熱器彈簧全啟式**閥適用于工作溫度≤400℃、A40Y-1≤450℃的空氣、水、氮?dú)浠旌蠚獾冉橘|(zhì)的設(shè)備或
管路上,A40Y-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(hù)裝置。
設(shè)計(jì)原理根據(jù)原理,可以設(shè)想,在線(又稱熱態(tài))測量或調(diào)整**閥時(shí),如果由外部提供一個(gè)向上的附加力,則當(dāng)
介質(zhì)壓力與這個(gè)附加力的總和剛剛克服彈簧預(yù)緊力時(shí),閥芯同樣也會(huì)開啟,甚至在沒有介質(zhì)作用的離線(又稱冷
態(tài))條件下,單獨(dú)由外部附加力克服彈簧預(yù)緊力時(shí),閥芯也可開啟,圖一清楚地表示了這種力的平衡關(guān)系。 很明
顯,我們可以看出,
閥芯開啟的條件為
FT=FW+PL×S 其中: FT——彈簧預(yù)緊力 FW——外部附加力 PL—— 介質(zhì)作用壓力 S——**閥密封面
面積 則開啟壓力P為:P=PL+FW/S 當(dāng)冷態(tài)時(shí),P=FW/S 顯然,如果能夠準(zhǔn)確地測定附加外力FW,就可以
根據(jù)已知的閥芯面積S和系統(tǒng)工作壓力,很容易地求得**閥的開啟壓力P。這即為**閥在線測試技術(shù)的設(shè)計(jì)依據(jù)
和原理。
