Zusammenfassung: | The utility model relates to the technical field of water supply, in particular to a stainless steel flange noise elimination check valve which comprises a valve body, a water inlet and a water outlet of the valve body are respectively provided with a flange plate, and a fence type installation plate is fixedly arranged on the inner wall of the water outlet of the valve body. The flange plate and the valve body are subjected to laser welding, so that the product sealing performance is high, the product cost is reduced, the manufacturing period is shortened, the service life is prolonged, the supply requirement of a water supply system is met, water flow enters a pipeline from a water inlet, and when the water flow pressure does not exceed a set pressure value in the pipeline, the water flow pressure does not exceed the set pressure value in the pipeline. And when the pressure value of the water flow in the pipeline is too large, the valve body descends to prevent the water flow from reversely flowing back fro |
