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