衛(wèi)生級式焊接式止回閥  Sanitary Welded 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閥桿上面的壓力以及彈簧力時(shí)，閥門就開啟，當(dāng)閥桿上、下壓力平衡時(shí)，閥門就會關(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)   如果閥門被安裝在一根垂直管道內(nèi)，開啟間門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 Welded 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.
