[0033] Specifically, the valve core mechanism includes a valve shaft 41 rotatably arranged on the valve body, a valve flap 42 fixedly arranged on the valve shaft, a plurality of reinforcing ribs 43 fixedly arranged on the valve shaft and the valve flap, a first gear 44 fixedly arranged at one end of the valve shaft, and a stop ring 45 fixedly arranged on the valve body. The valve flap and the valve shaft can rotate within the valve body to achieve the functions of cutting off liquid flow or throttling. The adjusting mechanism is used to adjust the rotation angle of the valve flap and the valve shaft to achieve the functions of cutting off liquid flow or throttling. The reinforcing ribs can strengthen the connection strength of the valve flap and the valve shaft to prevent the connection between the valve flap and the valve shaft from cracking due to long-term impact of liquid, which causes the valve flap to fail to completely close and further causes the butterfly valve to fail. The stop ring can limit the rotation of the valve flap to prevent excessive rotation of the valve flap.

[0034] Specifically, the adjusting mechanism includes a support column 51 fixedly arranged on the top of the valve body, an adjusting box 52 fixedly arranged on the support column, a first support sleeve ring 53 fixedly arranged on one side of the adjusting box, a first rotating shaft 54 rotatably arranged on the first support sleeve ring, an adjusting handle 55 fixedly arranged at one end of the first rotating shaft, a second gear 56 fixedly arranged at the other end of the first rotating shaft and engaged with the first gear, a limiting component 57 fixedly arranged on the other side of the adjusting box, and a prompting component 58 fixedly arranged on the first support sleeve ring and the first rotating shaft. The transmission ratio of the second gear to the first gear is four to one, i.e., the first gear rotates by 90 degrees when the second gear rotates by one revolution.
