[0002] Rain and sewage secondary treatment usually refers to rain and sewage secondary diversion, and it is a kind of drainage system, which refers to separating rainwater and sewage, conveying by a pipeline, discharging or subsequent treatment of sewage discharge mode.Rainwater is directly discharged into river through rainwater pipe network, and sewage is collected through sewage pipe network, then sent to sewage treatment plant for treatment, to avoid pollution caused by direct sewage into river.And the collection and centralized management and discharge of rainwater can reduce the impact of water quantity on sewage treatment plant, and ensure the treatment efficiency of sewage treatment plant.

[0003] At present, various water valves are usually needed in the rain and sewage secondary treatment process, and the common valves for sewage treatment include gate valves, stop valves, ball valves and butterfly valves.Because the wastewater of sewage treatment plant has strong corrosion, common strong acid and strong alkali, so the material of valve and pipeline is inclined to stainless steel 316 and titanium alloy, which has super corrosion resistance.

[0004] However, the water flow of the water valve used in the rain and sewage secondary diversion is usually relatively fixed, it is difficult to adjust the water flow according to actual needs, resulting in great limitation in use, even some adjustable ones are time-consuming and laborious to operate, and the positioning after adjustment is not reliable, so that the flow variability is large, which is difficult to meet the existing use needs.Therefore, we provide a water valve device for rain and sewage secondary treatment.
