Novel butterfly valve
The invention relates to a novel butterfly valve. The novel butterfly valve comprises a valve body (1) and a shaft (2), wherein a valve plate (3) is mounted on the shaft (2); a bottom plug (9) is mounted on the valve body (1) at the bottom of the shaft (2); the novel butterfly valve is characterized...

| description | The invention relates to a novel butterfly valve. The novel butterfly valve comprises a valve body (1) and a shaft (2), wherein a valve plate (3) is mounted on the shaft (2); a bottom plug (9) is mounted on the valve body (1) at the bottom of the shaft (2); the novel butterfly valve is characterized in that a part, near the valve body (1), of the shaft (2) is sleeved by a composite bush (6); a locating slot is formed in the shaft (2) in the valve body (1); an anti-thrust key (7) is mounted in the locating slot; an anti-thrust gasket (8) is mounted on a part, near the bottom of the shaft (2), of the bottom plug (9). Through the adoption of the anti-thrust gasket and the anti-thrust key, the axial movement amount of the valve plate part is effectively limited; meanwhile, a reasonable fit clearance is designed, so that a sealing ring and a valve body sealing surface are self-aligned in the rotation process of the valve plate, thereby effectively protecting a sealing pair, avoiding the damage to the sealing ring and the valve body sealing surface in the operation process of the valve, avoiding internal leakage caused by the damage to the sealing ring and the valve body sealing surface, and improving the sealing performance of the butterfly valve. |
