凸耳對(duì)夾雙瓣旋啟式止回閥產(chǎn)品簡(jiǎn)介: H76型凸耳對(duì)夾雙瓣旋啟式止回閥(美標(biāo)) H76 type lug and wafer type double discs swing check valve(ANSI standard) 凸耳對(duì)夾雙瓣旋啟式止回閥概述: H76型凸耳對(duì)夾雙瓣式止回閥用于管路系統(tǒng)中。該閥流道通暢阻力小,動(dòng)作靈敏,密封性能好。其主要作用是防止介質(zhì)倒流、防止泵及其驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn),以及容器內(nèi)介質(zhì)的泄放。所以被廣泛應(yīng)用于化工、醫(yī)藥、食品、市政水力等行業(yè)。該閥安裝位置不受限制,通常安裝于水平管路上,但也可以安裝于垂直管路或傾斜管路上。 凸耳對(duì)夾雙瓣旋啟式止回閥工作原理: H76型凸耳對(duì)夾雙瓣式止回閥開(kāi)啟時(shí),靠介質(zhì)的工作壓力把閥瓣沖開(kāi),此時(shí)閥門開(kāi)啟,介質(zhì)通過(guò);關(guān)閉時(shí),靠介質(zhì)逆流和閥瓣的自重,閥瓣繞閥體內(nèi)轉(zhuǎn)軸旋轉(zhuǎn),從而使閥瓣和閥座密合,達(dá)到關(guān)閉止回閥的目的。 凸耳對(duì)夾雙瓣旋啟式止回閥結(jié)構(gòu)特點(diǎn): H76型凸耳對(duì)夾雙瓣式止回系列閥門主要由閥體、閥瓣、閥桿及彈簧等結(jié)構(gòu)組成。由于閥體的結(jié)構(gòu)短、重量輕,閥瓣關(guān)閉行程短關(guān)閉迅速,減少水錘水擊等特點(diǎn)。閥瓣為半圓雙瓣結(jié)構(gòu),可繞閥體內(nèi)的轉(zhuǎn)軸旋轉(zhuǎn),轉(zhuǎn)軸的軸線必須和閥體密封面在一個(gè)平面上,保證關(guān)閉時(shí)達(dá)到密封。連接方式:采用了對(duì)夾凸耳結(jié)構(gòu),可使閥體外形更加美觀、休積小、重量輕。 凸耳對(duì)夾雙瓣旋啟式止回閥技術(shù)參數(shù): 產(chǎn)品名稱:凸耳對(duì)夾雙瓣旋啟式止回閥 產(chǎn)品型號(hào):H76H/W 產(chǎn)品材料:WCB、CF3、CF8、CF3M、CF8M 產(chǎn)品規(guī)格:DN50~1200、PN10~420 工作壓力:150LB/300LB/600LB/900LB/1500LB/2500LB |
