德国巴赫进口波纹管闸阀概述：Overview of bellows valves imported from Germany by Bach:

进口波纹管密封闸阀是采用*高性能金属波纹管+填料双重密封技术制造，杜绝了普通闸阀单一的密封填料出现老化泄露的缺点，不但提高了使用效能，大幅度增加使用上的安全性、可靠性，同时也减低了维修费用及次数。其关键部件金属波纹管，下端于阀杆组件采用滚焊技术焊接，上端与连接板滚焊焊接，在流体介质和大气之间形成一个金属屏障，确保阀杆部位零泄露。阀盖上的加脂接头可直接对阀杆、螺母和轴套进行润滑。产品广泛应用于：石油化工、化纤纺织、电厂、钢厂、塑料造纸、热油系统。

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.

进口波纹管闸阀的定义： Definition of imported bellows gate valve:  

1、波纹管密封闸阀，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接，在流体介质和大气之间形成一个金属屏障，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）若波纹管失效，阀杆填料也会避免泄漏，并符合密封标准。
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。

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.
