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