Recently, the factory is producing a batch of round flap valve, round flap valve is a one-way valve, mainly used in hydraulic engineering and other fields.

When the door is closed, the door panel is kept closed by its own gravity or counterweight. When the water flows from one side of the door to the other, the force of the water pushes the door plate of the door, causing it to rotate around the door shaft and open, thus allowing the water to pass smoothly. When the water flow has the trend of reverse flow, under the action of water pressure and the gravity of the door itself, the door will automatically close to prevent the reverse flow of water, so as to achieve the function of one-way water flow.

For example, at the exit of some drainage pipes, the door is opened during normal drainage, and if there is a trend of external water backpouring after the drainage, the door will be closed to prevent backpouring.

In the irrigation system, the round flap valve can be installed at the outlet of the irrigation channel. When irrigation is needed, water flows out of the channel and pushes the tap door open, allowing water to flow into the field. After irrigation is finished, the door is closed to prevent water loss in the channel and outside debris entering the channel.

In the city’s drainage pump station, when the pump station drains, the round clap door is opened, so that rainwater can be smoothly discharged into rivers and lakes; After the end of drainage, it can effectively prevent the river lake water back into the drainage pump station, to avoid the pump station flooded. In addition, at the outlet of the spillway in some reservoirs, if there is a need to prevent downstream water backpouring, the round flap valve can also play a good role in one-way control of water flow.

Valves for similar applications include Non Return Valve.Jinbin Valve customizes a series of valves such as gate valve, stainless steel penstock gate, double eccentric butterfly valve, large-diameter air damper, water check valve，discharge valve, etc. If you have any related needs, please leave a message below.You will receive a response within 24 hours and look forward to working with you.
