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