AI Technical Summary
Existing garment processing equipment is prone to backflow of water during the water intake process due to water outages or negative pressure, which can contaminate the tap water pipes. In addition, the one-way check valve is at risk of failure, making the water supply system unreliable.
The system employs an ejector structure, which ensures that the water flow can only flow in one direction by setting an anti-backflow gap and a sealing structure in the water supply line. A variable diameter flow channel is set downstream of the gap to reduce the flow velocity and flow rate of the backflowing water. Combined with a sealing ring, a seal is achieved to prevent water leakage.
It effectively prevents water backflow, maintains the reliability and sealing of the water supply system, avoids tap water pollution, and ensures smooth water intake and high-pressure flow.
