What is a flap valve?

The

boys' valve is a simple, one -way valve that allows gas or liquid flow in one direction while preventing the flow in the opposite direction. The valve reaches this target with a spring loaded or weighted flap located through the hole of the pipe, tube or pipe. The guy of the valve is released in the direction of the desired flow and is either forced to open in a current or in a distant manner. When the flow stops or releases remote control, spring or the flap weight closes it against the seal, which effectively prevents flow or gas back into the pipeline. The boy valve also prevents unwanted foreign objects to enter the pipe or channel to which it is connected. Due to their own simplicity and lack of complex control systems, it is also one of the simplest anemy valves to maintain. This makes the flap valve a particularly attractive option for systems that work hard and are rarely subject to very high pressure. This simplicity also makes flap valves very effective forApplication in remote areas where regular maintenance is impractical.

One of the most common domestic applications of the flap valve is the household toilet. This type of valve valve is remotely controlled by a rinsed button or lever and elevators so that the water in the tank flows down into the bowl to flush the toilet. As soon as the tank is empty, the valve is released to seal the outlet pipe and allow the tank to be filled again.

guy valves come in a wide range of sizes and patterns that range from small plastic valves one or two inches (about 3 to 5 cm) in diameter to huge versions of stainless steel several yards. The basic principle of surgery to solve the same; Large flap valves therefore remain as simple and easy to maintain as their smaller counterparts. However, large valves are more likely to open with pumped fluid flows at higher pressure than naturalGravitational drainage, with which it often occurs with small domestic valves.

The actual flap component can also be made of flexible material such as neoprene or silicone. The only real requirement for efficient operation of this type of valve is that the valve opens when it is subjected to a normal flow through the pipeline and after closing it forms a good seal. Human heart valves are classic examples of valve valve, which is sufficiently demonstrating great simplicity and reliability of design.
