Square runner ball

The utility model relates to a square runner ball, which comprises a ball body, the ball body is provided with a medium runner, a heating piece is arranged in the ball body, and the cross section of the medium runner is of a square structure. In the square flow channel ball body, the flow area is increased through the square medium flow channel, so that the passing speed of a low-temperature medium is reduced, washing to components such as a valve seat and the ball body is reduced, meanwhile, the vibration influence is relieved, and the service life of a valve is prolonged; the heating piece can heat the ball body to prevent the medium from solidifying at the sealing position of the ball body and the valve seat after the valve is closed to influence the action performance of the valve, and the valve is suitable for low-temperature medium working conditions. 本实用新型涉及一种方形流道球体，包括球本体，所述球本体设置有一介质流道，所述球本体内设置有加热件，所述介质流道的横截面为方形结构。该方形流道球体中，方形的介质流道增加了流通面积，进而降低低温介质通过的速度，减小对阀座、球体等部件的冲刷，同时减轻振动影响，提高了阀门的使用寿命；加热件可对球体进行加热，避免阀门
