截止閥標(biāo)準(zhǔn)

時(shí)間：2014-3-7閱讀：7887

截止閥的啟閉件是圓柱形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開(kāi)和全關(guān)，定做時(shí)允許作調(diào)節(jié)和節(jié)流。截止閥開(kāi)啟時(shí)，閥瓣的開(kāi)啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到zui大，表示閥門已達(dá)全開(kāi)位置。所以截止閥的全開(kāi)位置，應(yīng)由閥瓣的行程來(lái)決定。以上內(nèi)容均根據(jù)學(xué)員實(shí)際工作中遇到的問(wèn)題整理而成，供參考，如有問(wèn)題請(qǐng)及時(shí)溝通、指正。上海申弘閥門有限公司主營(yíng)閥門有：截止閥,角式截止閥,電站截止閥,波紋管截止閥,真空截止閥,抗生素截止閥,水封截止閥,氧氣截止閥,節(jié)流截止放空閥,低溫截止閥，高溫高壓截止閥,氣動(dòng)截止閥,電動(dòng)截止閥,氨氣截止閥,止回閥，閘閥,安全閥、保溫閥、低溫閥、球閥蝶閥、過(guò)濾器、放料閥、隔膜閥、旋塞閥、柱塞閥、平衡閥、調(diào)節(jié)閥、疏水閥、管夾閥、排污閥、排氣閥、排泥閥、氣動(dòng)閥門、電動(dòng)閥門、高壓閥門、中壓閥門、低壓閥門、水力控制閥、真空閥門、襯膠閥門、襯氟閥門。

截止閥的工作原理
打個(gè)比方，假設(shè)一個(gè)帶蓋的水缸，水從缸底進(jìn)入，從缸口流出，缸蓋就相當(dāng)于閥的關(guān)閉件。要是用手向上提起缸蓋，就相當(dāng)于截止閥的工作原理。要是用手向旁邊移開(kāi)缸蓋，相當(dāng)于閘閥的工作原理。本閥適用于PN 1.6～42MPa，工作溫度在-29～+570℃的石油、化工、火力電站冶金、城建等各種工況的管路上，切斷或接通管路介質(zhì)。根據(jù)用戶不同需要，驅(qū)動(dòng)裝置可配電動(dòng)、氣動(dòng)、液動(dòng)和手動(dòng)。
