產(chǎn)品主要優(yōu)點Product main advantages
1.波紋管密封截止閥，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焊接，在流體介質(zhì)和大氣之間形成- -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，使用壽命更長。
3.雙重的密封設(shè)計( 波紋管+填料)若波紋管不幸失效，閥桿填料也會避免泄漏，并符合國際密封標(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。
1. The bellows seal globe valve, which is key part of metal bellows, bottom stem adopts automatic seam welding and welding, the upper connection plate automatic welding seamwelding, between the fuid and the atmosphere to forma metal barrier, to ensure that the valve stem zero leakage.
2. The disc adopts the design of conical sealing surface and medium into a streamlined, better sealing performance, long service life.
3. Double seal design (bellows + packing)if the bllows unfortunately fails, stem packing also can avoid leakage,ａnd conform to the international standard of sealing.
4. The bonnet joint on own by fat, can be directly on the valve stem, nuts and sleeves for lubrication, add the lubricating oil is not only to the threads as traditional.
5. Human body engineering design of hａnd wheel, longer service life, easy and convenient to operate, more safeａnd reliable.
