WJ41H/W锻钢波纹管截止阀介绍 产品主要优点Product main advantages
1.波纹管密封截止阀，其关键部件金属波纹管，下端与阀杆组件采用自动滚焊焊接，.上端与连接板自动滚焊焊接，在流体介质和大气之间形成- -个金属屏障，确保阀杆零泄漏。2.阀瓣采用锥形设计，密封面与介质成流线形，密封性能更好，使用寿命更长。
3.双重的密封设计( 波纹管+填料)若波纹管不幸失效，阀杆填料也会避免泄漏，并符合国际密封标准。
4.阀盖上自带有加脂接头，可直接对阀杆、螺母和轴套进行润滑，不像传统的只对螺纹加润滑油。
5.人体工程学设计手轮，使用寿命更长，操作轻松便捷，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.
