直流式波紋管截止閥結(jié)構(gòu)合理、密封可靠、性能優(yōu)良、造型美觀;密封面堆焊Co基硬質(zhì)合金、耐磨、耐腐、抗摩擦性能好、使用壽命長;Straight through type bellows globe valve is reasonable in structure, reliable sealing, excellent performance, attractive appearance; Co based cemented carbide sealing surface welding, wear, corrosion, anti friction performance, long service life德標(biāo)Y型直流式波紋管截止閥閥桿調(diào)質(zhì)及表面氮化處理,有良好的抗腐和抗摩擦性能;雙重密封,性能更可靠;閥桿升降位置指示更直觀。
進口直流式波紋管截止閥,閥體的流道與主流道成一斜線,這樣流動狀態(tài)的破壞程度比常規(guī)截止閥要小,因而通過閥門的壓力損失也相應(yīng)的小了。
產(chǎn)品特征:
1.Y型直流式波紋管截止閥,其關(guān)鍵部件金屬波紋管,下端與閥桿組件采用自動滾焊焊接,上端與連接板自動滾焊接,在流體介質(zhì)和大氣之間形成一個金屬屏障,確保閥桿零泄漏;
2.閥瓣采用錐形設(shè)計,密封面與介質(zhì)成流線形,密封性能更好,密封面間磨擦力小,使用壽命更長;
3.雙重的密封設(shè)計(波紋管+填料)若波紋管失效,閥桿填料也會避免泄漏,并符合密封標(biāo)準(zhǔn);
4.閥蓋上自帶有加脂接頭,可直接對閥桿、螺母和軸套進行潤滑,不像傳統(tǒng)的只對螺紋加潤滑油;
5.人體工程學(xué)設(shè)計手輪,使用壽命更長,操作輕松便捷,更安全可靠;
6.工作行程小,啟閉時間短;
參數(shù):
應(yīng)用:熱油系統(tǒng)、蒸汽系統(tǒng)、冷熱水系統(tǒng)。
適用溫度:-20℃----350℃
適用公稱壓力:PN1.6-4.0Mpa
口徑:DN15-DN400
進口波紋管截止閥,BELLOWS GLOBE VALVE,也叫波紋管密封截止閥,是指采用雙重的密封設(shè)計(波紋管+填料)結(jié)構(gòu)設(shè)計,密封性好,特別適用于蒸汽、導(dǎo)熱油、劇毒、強腐氣液介質(zhì)密封可靠性要求特別高的工況。
