Injection molding ball valve and manufacturing method thereof

The invention provides an injection molding ball valve. The valve comprises a valve ball, a valve rod and a valve body, wherein the valve ball is arranged in the valve body, the valve ball is connected with the valve rod; and the valve is characterized by further comprising an inner valve liner, wherein the inner valve liner is positioned between the valve ball and the valve body, the inner wall of the inner valve liner is matched with the outer wall of the valve ball, and the outer wall of the inner valve liner is matched with the inner wall of the valve body. When the ball valve is manufactured, the valve ball is arranged in the inner valve liner, and then the valve body is injected and molded on the outer side of the inner valve liner. The valve and method have the advantages that the problem that regarding the injection molding ball valve, a handle for controlling the valve ball is difficult to twist is solved. 一种注塑球阀，包括阀球、阀杆、阀体，所述的阀球安装在阀体内，阀球与阀杆连接，其特征在于:还包括内阀胆，所述的内阀胆位于阀球和阀体之间，内阀胆的内壁与阀球外壁匹配，内阀胆的外壁与阀体的内壁匹配
