波纹管阀门特征BELLOWS VALVE FEATURES:
a:阀体采用精密铸造工艺，先进的工艺了确保阀体无砂眼，表现光滑，质量更可靠。The valve body adopts investment casting technology.Advanced technology to ensure that the valve body has no sand holes,surface more smooth and quality more reliable.

b:锥形密封面能自动清除杂质Conical sealing surface will remove impurity automatically.

c:活动插销，易更换阀瓣Flexible pin,easy to replace the disc when broken.

d:波纹管是波纹管阀门的关键组件，采用自动滚焊，焊在阀瓣与阀杆上，确保阀杆部件100%零泄露。Bellow is the key part of bellow sealed valves,which is welded to both the valve bonnet and valve stem,with automatic roll welding.The metal bellow can keep the stem part 100% no leakage.

e:波纹管材质为不锈钢，3层波纹管，使用寿命达5000次。Three layers stainless steel bellows can be use 5000 times.

f:波纹管上端焊接上碗盘，下端焊接在阀杆，保证介质不会从阀杆泄露。The upper end of the bellows is welded to the bowl plate,and the lower end is welded to the valve stem to ensure that the medium does not leak from the valve stem.

g:定位片，能起到限位开关的作用，更好的保护阀门The guide piece limit the valve to open and close,better to protect the valve.

h:石墨填料，第二道密封的作用Graphite packing was the second sealing for valves.

i:人体工程学设计手轮，使用寿命更长，操作轻松便捷且安全可靠。Ergonomic hand wheel.It provide longer service life and easier Operation.
