[0024] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.
[0025] Embodiment: First, pour the material from the upper inlet of the valve body 1. When the material level meter 3 located above is equipped with a radar sensor, the material amount in the upper cavity is detected. When the predetermined amount is reached, the electrical centralized controller controls the hydraulic device 2 above. The hydraulic device 2 drives the shaft to rotate, the shaft drives the connecting rod to rotate, and the connecting rod drives the valve plate 6 to rotate, so that the valve plate 6 contacts the inlet. The inlet is smaller than the nylon plate 8. When the nylon plate 8 contacts the inlet, the nylon plate 8 is pressed down and the return spring 7 is compressed. At this time, the lower The hydraulic device 2 drives the valve plate 6 below to rotate and open, so that the material falls from the internal middle opening into the lower cavity. When closed, the valve plate 6 is lifted up from bottom to top under the drive of the hydraulic device 2, and after 6 presses the reset spring 7, it presses the anti-dust nylon plate 8, and is pressed together with the rubber ring of the feed inlet to form a seal without leakage and airtightness. When opened, the valve plate 6 moves downward, and after there is no hydraulic pressure, the reset spring 7 quickly pushes the nylon plate 8 and the valve plate 6 apart, forming vibration. Under this action, the sticky ash falls into the ash discharge valve, achieving the purpose of self-cleaning.
