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