Background
Since the invention of the regulating valve, the medium flow is regulated by utilizing the position change of a valve core of the regulating valve relative to a valve seat, and the regulating method is simple, quick and applicable and is still a widely adopted regulating method. However, in modern industrial production, the above-mentioned adjusting method is greatly challenged, when used for two-phase flow working medium with great erosion-wear property, even if the valve core and the valve seat made of tungsten carbide or engineering ceramic material with great abrasion resistance are adopted, the sealing surface of the valve ball and the valve seat is worn quickly under the erosion-wear of the black water and slag water two-phase flow working medium, so that the sealing capability is lost, and the service life is ended.
The opening/closing function and the flow rate regulating function of the conventional ball valve are realized by changing the relative positions of the valve seat and the valve ball, and when the central line of a valve ball channel is superposed with the central line of a valve body flow channel, the valve is in an opening state, as shown in fig. 11; when the valve ball rotates 90 degrees and the central line of the valve ball hole is vertical to the central line of the valve body flow passage, the valve is in a closed state, as shown in figure 12. Anywhere between 0 and 90 deg., in the flow regulating position, as shown in fig. 13. While the working medium flows through the channel, solid materials in the medium abrade the sealing surfaces of the valve seat and the valve ball, and particularly the solid materials in black water and slag water abrade the sealing surfaces of the valve seat and the valve ball to the extent of sealing failure in a short time.
