3.Structural features of 리프트 글로브 밸브:
1) The sealing parts of the 리프트 글로브 밸브 are the valve disc and the valve seat. In order to make the 리프트 글로브 밸브 close tightly, the mating surface of the valve disc and the valve seat should be ground or gaskets, and the sealing surface can also be inlaid with bronze, stainless steel, etc. , Wear-resistant materials. The valve disc and the valve stem of 리프트 글로브 밸브 are movably connected to facilitate the tight fit between the valve disc and the valve stem.
2) The lifting of the valve disc of 리프트 글로브 밸브 is generally controlled by the valve stem. The upper part of the 리프트 글로브 밸브 stem is a handwheel, and the middle part is a thread and packing seal section. The function of the packing is to prevent the medium inside the valve body from leaking along the valve stem.
3) The main function of 리프트 글로브 밸브 in chemical pipelines is to cut off or connect fluid. 리프트 글로브 밸브's regulating flow is better than gate valves, but 리프트 글로브 밸브 cannot be used to regulate pressure and flow for a long time. Otherwise, 리프트 글로브 밸브 sealing surface It may be eroded by the medium and damage the sealing performance.
4) 리프트 글로브 밸브 can be used in pipelines such as water, steam, and compressed air, but it is not suitable for medium pipelines with high viscosity, easy coking, and easy precipitation, so as not to damage the sealing surface.
