Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
Referring to as shown in Figure 1 and Figure 2, present embodiment adopts the following technical scheme that：It includes butterfly valve butterfly plate 1, fixes
Pressing plate 2, sealing ring 3, adjusting screw 4, butterfly valve seat 5, sealing mat piece 6, main shaft intert groove 7, Fixed latches groove 8；The butterfly valve
A circle sealing ring 3 is fixed with by fixation clip 2 at the outer ledge of butterfly plate 1, sealing ring 3 passes through adjusting screw 4 and butterfly valve butterfly
Plate 1 connects, and the butterfly valve butterfly plate 1 is fixed on the inner side of butterfly valve seat 5 by main shaft, and the inner side of butterfly valve seat 5 is provided with sealing
Mat piece 6, sealing mat piece 6 cooperate with sealing ring 3；The back side of the butterfly valve butterfly plate 1 is provided with a pair of of main shaft and interts groove 7,
The outside that main shaft interts groove 7 is provided with Fixed latches groove 8.
Preferably, incision position is provided with hole seam allowance 9 on the outside of the inserting groove of the adjusting screw 4.
Preferably, the upper end of the butterfly valve seat 5 is provided with mechanical position limitation part 10, the inside of mechanical position limitation part 10 is set
There is a pair of spacing block piece 11, and rotation fastener 12 is provided between spacing block piece 11, rotate fastener 12 and butterfly valve main shaft 13 is coaxial
Connection.
Preferably, the butterfly valve butterfly plate 1 uses truss structure, both sides are provided with support reinforcing plate.
