進(jìn)口波紋管閘閥
德國(guó)巴赫進(jìn)口波紋管閘閥概述：
進(jìn)口波紋管密封閘閥是采用*高性能金屬波紋管+填料雙重密封技術(shù)制造，杜絕了普通閘閥單一的密封填料出現(xiàn)老化泄露的缺點(diǎn)，不但提高了使用效能，大幅度增加使用上的安全性、可靠性，同時(shí)也減低了維修費(fèi)用及次數(shù)。其關(guān)鍵部件金屬波紋管，下端于閥桿組件采用滾焊技術(shù)焊接，上端與連接板滾焊焊接，在流體介質(zhì)和大氣之間形成一個(gè)金屬屏障，確保閥桿部位零泄露。閥蓋上的加脂接頭可直接對(duì)閥桿、螺母和軸套進(jìn)行潤(rùn)滑。產(chǎn)品廣泛應(yīng)用于：石油化工、化纖紡織、電廠、鋼廠、塑料造紙、熱油系統(tǒng)。
bellows gate valve
Introduction of Bach bellows gate valve:
Bellows seal gate valve is the use of advanced high performance metal bellows + double sealing filler manufacturing technology, to eliminate the packing single ordinary gate valves aging leakage faults, not only to improve the use efficiency, increase safety and reliability in use, but also to reduce the maintenance cost and the number of times. The key parts of metal corrugated pipe, the lower on the stem assembly with seam welding technology, and the upper end of the connecting plate roll welding, forming a metal barrier between the fluid and the atmosphere, to ensure that the stem parts of zero leakage. Fatliquoring joint valve cover can direct the lubrication of the valve rod, nut and sleeve. The products are widely used in petroleum chemical industry, chemical fiber textile, power plants, steel mills, plastic paper, thermal oil system.
的定義：
1、波紋管密封閘閥，其關(guān)鍵部件金屬波紋管，下端與閥桿組件采用自動(dòng)滾焊焊接，上端與連接板自動(dòng)滾焊接，在流體介質(zhì)和大氣之間形成一個(gè)金屬屏障，確保閥桿零泄漏。
2、閥瓣采用錐形設(shè)計(jì)，密封面與介質(zhì)成流線形，密封性能更好，使用壽命更長(zhǎng)。
3、雙重的密封設(shè)計(jì)（波紋管+填料）若波紋管失效，閥桿填料也會(huì)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(duì)閥桿、螺母和軸套進(jìn)行潤(rùn)滑，不像傳統(tǒng)的只對(duì)螺紋加潤(rùn)滑油。
The definition of imported bellows valve:
1, bellows seal valves, its key components - metal bellows, bottom and stem components with automatic roll welding, welding, automatic roll the upper end of the connecting plate, forming a metal barrier between the fluid and the atmosphere, to ensure zero stem leakage.
2, the valve flap with a tapered design, sealing surface and the media into a linear flow, sealing performance is better, longer life.
3, the double seal design (bellows + filler) if the bellows failure, stem packing will avoid leakage, and in line with international standards.
4, the valve cover is provided with grease lubrication of the joints, can be directly stem, nut and sleeve, unlike traditional thread only to add the lubricating oil.
