說明:
匯豐青島先導(dǎo)式安全閥主要用于電站鍋爐、壓力窗口及減濁減壓裝置等設(shè)備,防止壓力超過允許壓力值 ,以確保設(shè)備的安全運(yùn)行。
This valve is used for power boilers,pressure containers,pressure and temperature reducing device and other facilities.It serves to prevent the pressure exceeding the highest allowable pressure value and ensure the safety of the device when working.
匯豐青島先導(dǎo)式安全閥結(jié)構(gòu)簡述:
1:先導(dǎo)式安全閥是通過杠桿和重錘來平衡閥瓣的壓力,使閥門保證密封,移動(dòng)重錘的位置和改變重錘的重量來達(dá)到要求的起跳壓力。
2:安全閥密封面用鐵基鉻鎳不銹鋼堆焊而成,閥瓣經(jīng)熱處理,提高了耐磨性和抗沖擊蝕性。
3:閥門上部帶有開啟和關(guān)閉的電磁鐵,機(jī)械和電器動(dòng)作互不干擾。
