H42W不銹鋼底閥結(jié)構(gòu)與原理: 不銹鋼法蘭底閥由閥估,閥瓣,閥蓋，上海雙口止回閥圖片,襯套,密封圈等零件組成,詳見下圖水源的水從閥蓋進入閥體.在流體的壓力作用下,閥瓣打開水,當示停后出口管內(nèi)的壓力將閥瓣迅速關(guān)閉,液體將不會倒回水源,起到了即暢通抽水又節(jié)約水能損失的作用. 底閥應(yīng)用范圍： H42W不銹鋼底閥設(shè)計合理，制造工藝先進，安裝、使用、檢修方便。并具有摩擦阻力小，使用壽命長，節(jié)能等優(yōu)點，通常適用于石化、化工、紡織，上海雙口止回閥圖片，上海雙口止回閥圖片、印染、冶金、礦山、排灌等行業(yè)的水泵配套設(shè)施。</p><div style="width:100%;text-align: center;"><img
