The working principle of this patented product is that when draining is needed, the drained water enters the internal drain trough through the upper drain of the valve, and automatically opens the sealing flap in the valve body under the action of water gravity so that the water is discharged into the sewer through the drain; After emptying, the sealing flap no longer bears the water discharge pressure. At this time, the automatic flap returns to the original position under the action of the balance weight and seals the drain port to prevent overflow. Prevent dirty water or odor from overflowing from the sewage pipe and polluting the upper water pipe or indoor air. Overcome the water-sealed floor drain and the S-type and P-type traps, which are prone to breed microbial bacteria to contaminate the pipes due to water retention, and if the water is not drained for a long time, the water in the water seal will still contaminate the pipes due to natural evaporation after communicating with the upper pipe The shortcomings, this product is most suitable for installation on the drain port of the water pipe emptying antifreeze valve. Play a role in preventing overflow. It can also be installed on the drain pipes of wash basins, sinks, bathtubs, etc. Prevent the phenomenon that the water in the internal network of the water seal is easy to ball up and even freeze to be unable to drain after drainage in winter.
The product has the advantages of simple structure, convenient installation and operation, long service life and low maintenance cost. It can bring free drainage, and automatically realize the environmental protection effect of preventing overflow after drainage. The commonly used specifications of the products are DN15, DN20, DN32, DN40, etc. Village quality includes brass and PPR.
