RETZ瑞茨『進(jìn)口對(duì)夾雙瓣止回閥』詳細(xì)介紹●RETZ止回閥系列●RETZ對(duì)夾雙瓣止回閥●產(chǎn)品數(shù)據(jù)
?描述--
RETZ進(jìn)口對(duì)夾雙瓣止回閥亦稱之為蝶式雙瓣止回閥,閥板為兩個(gè)半圓，且采用彈簧強(qiáng)制復(fù)位,適用于中小口徑的場(chǎng)合,當(dāng)介質(zhì)按規(guī)定方向流動(dòng)時(shí)，閥瓣受介質(zhì)力的作用，被開啟;介質(zhì)逆流時(shí)，因閥瓣自重和閥瓣受介質(zhì)反向力的作用，使閥瓣與閥座的密封面密合而關(guān)閉，達(dá)到阻止介質(zhì)逆流的目的
RETZ imported double valve check valve is also called butterfly double valve check valve, and the valve plate is two semicircle, and the spring is forced to reset. It is suitable for small and medium size occasions. When the medium is flowing in the prescribed direction, the valve is opened by the action of medium force. When the medium is countercurrent, the valve's self weight and the valve disc are affected by the reverse force of the medium. The sealing surface of the disc and the valve seat is closed and closed, so as to prevent the media from countering the flow.
?性能特點(diǎn)--
1.安裝在法蘭之間
2.可適合用于不同的連接方式
3.低水頭損失
4.不誘鋼彈簧I避免水錘現(xiàn)象。
5.采用低溫粉末噴塑，防止密封閥座副產(chǎn)生高溫老化，提高使用壽命。
6.密封圈采用多條窄帶設(shè)計(jì)，閥座直接硫化到閥體上，使密封性能達(dá)到*密封，實(shí)現(xiàn)零泄漏。
7.結(jié)構(gòu)性能安全可靠抗干擾性強(qiáng)關(guān)閉速度快，水頭損失小。
8.結(jié)構(gòu)長度短剛性好安裝方便。
