The aerator is one of the important accessories of the faucet. It is usually installed at the water outlet of the sink faucet. The aerator can mix the water and the air to produce a foaming effect, thereby effectively reducing the amount of water and saving water. However, its function is often ignored by users. The original faucet is not equipped with a aerator.
In the early days, people used water in such a way that when the faucet was opened, the water would rush out of the outlet. The flow rate was large and the initial velocity direction was not constrained. The water flow was not linear but was similar to a conical shape and the surface was irregular. The water was often sprayed in unnecessary places even spilled on the user. Although the faucet without the aerator has a large flow rate and a high water output, there are some problems. The first is the waste water. The water supply pressure in the general household is about 0.3 MPa. The faucet is already at the maximum flow rate when the faucet is opened. The adjustment range is limited, and the water flow is not constrained. This causes some water flow to be not effectively utilized, such as washing vegetables, a large and unconstrained flow of water wastes water and does not wash the vegetables thoroughly; the second is that the shape of the effluent of the faucet is unstable, and the water is easily splashed on the user; the third is that impurities in the water supply pipeline will flow out with the flow of water, the water with impurities will be released, which also causes waste of water resources; the fourth is that there is no limit to the pressure of the water, the pressure of the water is large, and the water will hit the human skin with a feeling of pain.
In order to solve the problem of splashing water when the faucet is out of the water, the great inventors screwed out the thread at the faucet outlet, screwing the matching metal ring on the water outlet to form the flow regulator of faucet, This is why the early faucet spout was called a Flow regulator. In order to filter the impurities in the water, a stainless steel wire mesh is added to the beam, so that the prototype of the aerator is formed, and the flow restriction can be achieved by appropriately increasing the number of layers of the stainless steel mesh and the density of the holes.
The function of aerator
- Filtration: The aeratorcan filter some sediment and impurities in the water. The aeratorcan filter impurities, which will inevitably become blocked and will need to be cleaned. The aerator can be removed, soaked in vinegar, cleaned with a small brush or other tool, and then reinstalled.
- Water saving: The aeratorcan make the water flow and the air fully contact, forming a foaming effect, thereby reducing the water consumption. Generally, the faucet with the aeratorinstalled saves about 30% of the water.
- Splash-proof: water will become soft after mixing into the air, reducing the impact. It can prevent water from splashing everywhere, and it can also achieve good noise reduction.
