AI Technical Summary
In existing negative pressure water supply equipment, the sealing rings at the connection between the pipeline and the negative pressure buffer tank are worn due to water pump vibration, resulting in poor sealing performance and affecting equipment performance.
The structure employs a sliding ring and a high-strength spring. The sealing ring drives the limiting ring to slide, while the high-strength spring provides rebound force to ensure that the sealing ring fits tightly against the connection surface, reducing wear. The arc-shaped block drives the sliding rod to generate rebound force to buffer the shaking of the connecting pipe and maintain a stable position.
It effectively prevents the sealing ring from wearing due to vibration, ensures the sealing of the connection parts, guarantees the stable operation of the equipment, and reduces noise interference.
