The diamond material and diamond composite material ball valve comprises a valve body and a spherical valve element, a valve cavity is formed in the valve body, a first rough surface is arranged on the surface of an inner cavity of the valve cavity, a second rough surface is arranged on the surface of the spherical valve element, a first diamond composite layer is arranged on the first rough surface, and a second diamond composite layer is arranged on the second rough surface. A second diamond composite layer is arranged on the second rough surface, a vertically upward valve rod penetrating through the valve body is arranged on the spherical valve element, and a positive pressure sealing mechanism is arranged between the valve body and the valve rod; the inner wall of the valve cavity is provided with an inflation sealing mechanism for sealing the joint of the valve body and the valve cavity. According to the invention, the wear resistance and corrosion resistance of the valve cavity are effectively improved, so that the service life of the valve body is prolonged, the leakage phenomenon between the valve cavity and the spherical valve core is avoided, and meanwhile, the production precision requirements of the valve cavity and the spherical valve core are reduced.
