style="text-indent:25px">用波紋管作為閥桿密封元件的閥門。它常用于對(duì)閥桿密封要求嚴(yán)格的場(chǎng)合，如用于高真空的場(chǎng)合和核工業(yè)中。采用波紋管代替普通閥門上的填料函或與填料函并用，單壁波紋管設(shè)備生產(chǎn)企業(yè)，可使閥桿部位無泄漏，以防止放射性物質(zhì)或貴重物質(zhì)外漏，或保持高真空。波紋管隨閥桿的升降而伸縮，其比較高工作壓力取決于波紋管的耐壓強(qiáng)度和疲勞強(qiáng)度。上海卓帕真空技術(shù)有限公司座落于浙江溫州永嘉甌北，是一家集科研，單壁波紋管設(shè)備生產(chǎn)企業(yè)，生產(chǎn)及銷售鍛鋼閥門的專業(yè)生產(chǎn)產(chǎn)家。公司技術(shù)力量雄厚，設(shè)備精良，工藝先進(jìn)，單壁波紋管設(shè)備生產(chǎn)企業(yè)，全部采用現(xiàn)代化精密數(shù)控機(jī)床及各種專業(yè)加工機(jī)器進(jìn)行加工生產(chǎn)，擁有各類加工及檢測(cè)設(shè)備30多臺(tái)，公司通過了ISO9001認(rèn)證，歡迎大家前來選購產(chǎn)品。無論是強(qiáng)制更換的波紋管數(shù)量，還是由此而產(chǎn)生維修費(fèi)用，或者設(shè)備的停機(jī)時(shí)間，都比PTFE波紋管閥明顯要多。單壁波紋管設(shè)備生產(chǎn)企業(yè)</p><div
