1results about How to "Prevent siphon phenomenon" patented technology

The application discloses a gas-water diversion anti-siphon device, which comprises a water storage tank body, a water inlet pipe joint, a water outlet pressure-limiting backflow valve assembly, a pressure-loss air inlet valve assembly and a pressure-loss water outlet valve assembly. The water inlet pipe joint is arranged at the upper half of the water storage tank body and is connected with a water supply pipe network. The water outlet pressure-limiting backflow valve assembly is arranged at the lower half of the water storage tank body and is connected with downstream water using appliances. The pressure-loss air inlet valve assembly and the pressure-loss water outlet valve assembly are arranged at the top end and the bottom end of the water storage tank body, respectively. When the water supply pipe network is shut down and negative pressure is generated, the pressure-loss air inlet valve assembly is opened to enable air to enter the water storage tank body and flow into the water supply pipe network through the water inlet pipe joint. Meanwhile, the pressure-loss water outlet valve assembly is opened to discharge the accumulated water in the water storage tank body. Meanwhile, the water outlet pressure-limiting backflow valve assembly is closed to prevent downstream water from flowing back into the water storage tank body.
