Lining silicon nitride ceramic wear-resistant disc valve facilitating installation of transmission assembly

The utility model discloses a lining silicon nitride ceramic wear-resistant disc valve convenient to install a transmission assembly, which comprises a valve body, a support connected to the top, clamping blocks embedded in the valve body, two clamping blocks connected in the support in a penetrating manner, a spring and a fixing lug connected between the two clamping blocks, and a clamping block connected to the bottom, and rotating shafts are movably connected into the fixing lugs, and connecting frames are movably connected to the surfaces of the rotating shafts. According to the silicon nitride ceramic lining wear-resistant disc valve facilitating installation of the transmission assembly, the support is placed at the top of the valve body, then the connecting frame is pressed, one end of the connecting frame drives the two clamping blocks to get close to each other, meanwhile, the two clamping blocks extrude the spring, the spring deforms, then the clamping blocks penetrate through the support to be in b
