What is a duck valve?
duck valve is a plumbing component used to control water flow or other liquids in the pipeline. These valves allow the fluid to flow in one direction only inside the pipeline and at the same time prevent the flow of the liquid in the opposite direction. This flow control technique helps to prevent unwanted materials contaminating water supply. They get their name from their appearance, which resembles a closed duck account under normal conditions. In some parts of the world, the duck valve may also be known.
Each duck valve resembles a rubber shift or nipple with a flange end. The nozzle consists of two lips or flaps that meet to create a point. The flange part of the valve is conveniently suitable around the pipe walls and another pipe is connected over the end of the valve. As the water flows through the pipe, the pressure it creates forces the lips of the account to open, allowing water. Due to insufficient pressure in the direction of the direction, the lips cannot open to allow water flow in the opposite direction.
The most common duck valve models are made of elastomeric materials and are designed for general purposes. Special coatings or materials are used to create valves at food level as well as valves used in medical environments. In a corrosive environment, the duck valve can consist of corrosion resistant materials designed to withstand the effects of harsh chemicals. Other varieties are made to withstand extreme temperatures or high pressure.
One of the primary advantages of the duck valve is its relatively simple design and easy installation. These valves contain few operating parts and require low maintenance. They work automatically on the basis of water pressure without the necessary equipment or manual activation. They also have a relatively low cost Compace for other types of back flow devices. In case of changes in damage or plumbing changes, these valves can be easily removedand replace to make the system efficiently functioning.
These valves must be carefully dimensioned to match the diameter of each pipe to ensure that they work as intended. The duck valve that is too large for pipes may not allow sufficient flow, while those that are too small may not be effective in preventing contamination. Compared to metal valves, the rubber valve of the duck valve can leave more vulnerable damage and corrosion over time.
