衛(wèi)生級(jí)止回閥系列 Sanitary Check Valve
應(yīng)用 止回閥應(yīng)用于不銹鋼管道系統(tǒng)內(nèi)，以達(dá)到防止液體回流的目的。
工作原理 當(dāng)閥桿下部的壓力超過(guò)閥桿上面的壓力以及彈簧力時(shí)，閥門(mén)就開(kāi)啟，當(dāng)閥桿上、下壓力平衡時(shí)，閥門(mén)就會(huì)關(guān)閉。一個(gè)更高的逆向壓力作用于閥桿使其關(guān)閉
材質(zhì) 產(chǎn)品與介質(zhì)接觸部分304或316L 密封材料: EPDM橡膠
連接形式 焊接式、螺紋式、止箍式、法蘭式 與管道或設(shè)備的連接方式均按
DIN11850,IDF/ISO"SMS國(guó)際標(biāo)準(zhǔn)尺寸制造，保障與進(jìn)口設(shè)備的連接與互換。
技術(shù)數(shù)據(jù) 如果閥門(mén)被安裝在一根垂直管道內(nèi)，開(kāi)啟間門(mén)所需要的不同的壓力大約為:
輸送物料壓力:10bar 溫度: 140℃ (EPDM ) 溫度:- 10℃
Sanitary Check Valve
Application Checkvalve is used in stainless steel pipe system topreventreverse flow.
Workingprinciple Thevalve opens when the pressure below the valve plugexceedsthe pressure above the plug plus spring force. The valve close when pressureequalization has beenachievedA higher counter pressure will press the v alveplugagainstthe seat and makes the valve closed
Material Materialcintact surface Sealing material: EPDM
Connectionstyle Welded,threaded ,clamped ,flange
Toassure the connection and substitution with imported facilities all theConnection styles with pipe or equipment are made to DlN 11850,lDF/lSO,SMS internationalstandard size.
Technical date Roquireddifferential pressures to turn on the valve that fitted in a vertical pipeline areabout:
Max.Pressure for transfer material:10 bar
Max.Temperature: 140℃(EPDM)
Min.Temperature:-10℃
