3.Structural features of Lyft klotventil:
1) The sealing parts of the Lyft klotventil are the valve disc and the valve seat. In order to make the Lyft klotventil 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 Lyft klotventil are movably connected to facilitate the tight fit between the valve disc and the valve stem.
2) The lifting of the valve disc of Lyft klotventil is generally controlled by the valve stem. The upper part of the Lyft klotventil 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 Lyft klotventil in chemical pipelines is to cut off or connect fluid. Lyft klotventil's regulating flow is better than gate valves, but Lyft klotventil cannot be used to regulate pressure and flow for a long time. Otherwise, Lyft klotventil sealing surface It may be eroded by the medium and damage the sealing performance.
4) Lyft klotventil 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.
