In order to control the opening or closing of various types of pipelines, various valves are installed in the pipeline to control the supply or stop of various raw materials by opening or closing the valves. Among the various raw materials, some of the raw materials are corrosive'. There is a high requirement for the materials of the various components in the pipeline. The ceramics are superior to other materials in terms of chemical corrosion resistance, wear resistance and high temperature resistance, so they are widely used. Applies to locations where metal materials cannot be used. The inside of the valve needs to be in contact with the raw material, and the valve core and the valve body often need to be rotated and rubbed. Therefore, the ceramic material valve has a high demand in the pipeline of some raw materials. In the past, some manufacturers installed a spherical valve core in the valve body and set a passage in the spherical valve core. When the passage of the valve core coincides with the passage of the valve body, the valve is opened and the raw material can pass through the valve. When the spool is rotated and the passage of the valve is not connected to the passage of the valve body, the valve is closed and the raw material will not pass through the valve. This - ball valve construction can achieve the effect of controlling the supply or stop of the raw material 'but the spherical core needs a larger "in order to work." Moreover, the U-shaped torque of the U-shaped body is large, and the friction area with the valve seat is also large, and the rotation of the k-shaped valve core is laborious, and the loss of the valve stem is relatively large. 10120759卢单号 A01〇l »31/ n / Total 14 pages ‘ 1012024728-0 [0003] M440373 [New content] One of the purposes of this creation is to provide a construction of a plug valve, especially a ceramic plug valve.
