style="text-indent:25px">液壓快速接頭無法對環(huán)境條件的變化、蒸汽溫度或流量的變化進(jìn)行有效的調(diào)節(jié)補(bǔ)償。液壓快速接頭是一種用來調(diào)節(jié)氣壓和溫度的裝置，特別是在火力發(fā)電站中，鍋爐一般都配有液壓快速接頭，防止鍋爐等設(shè)備因超溫或者超壓而損壞。同時，在化工、輕工、醫(yī)藥、食品加工等一切使用蒸汽的生產(chǎn)工藝流程中，過熱蒸汽作為機(jī)械能量的產(chǎn)生提供了很好的能源。而許多情況下，飽和蒸汽是更適合使用的，由于工藝及設(shè)備的原因，對壓力、溫度的控制也是必不可少的，通過液壓快速接頭可以得到合適的動力蒸汽。液壓快速接頭將冷卻水從不同形式的噴嘴處以霧狀噴入文氏管或蒸汽管道的蒸汽中。上海測壓系統(tǒng)液壓元件廠</p><p
