AI Technical Summary
The existing three-way shuttle valve is prone to seal failure under high water pressure conditions, leading to seal failure.
It adopts an elliptical sealing structure with protruding sealing contacts on both the inner and outer sides of the sealing interlayer. Sealing grooves are provided on the port and nut. After tightening the nut, the sealing contacts are pressed into the sealing groove to form a point-to-surface seal, thereby improving the sealing performance.
It achieves efficient sealing under high water pressure environment, avoiding sealing failure caused by misalignment of the sealing ring.
