The working principle, advantages and maintenance of self-closing faucets

The self-closing faucet can automatically shut off the water flow after a preset time to achieve the purpose of saving water. In many public places, we can often see its application. Of course, many families also choose to install such self-closing faucets in order to save water resources and reduce water bills. Before buying, I think you need to figure out these few questions - how do they work; what are their benefits; how are they maintained? Hope this article helps you.

How do they work?

Stage 1: When the self-closing faucet is pressed, the lower lip seal empties the chamber below it, and at the same time, the closed O-ring loses its seal, allowing water to flow to the outlet.

Stage 2: When the button is released, the return spring creates a negative pressure under the lower lip seal. The pressure imbalance between the two areas at the lower lip seal is balanced by the time delay hole and the spring. The channel gap between these two components creates a tiny water channel that fills the lower chamber, rebalancing the pressure and allowing the faucet to rise back up and close. The time required for the chamber below the lower lip seal to fill corresponds to the time required for the faucet to automatically close.

What are their advantages?

1. Prevent cross-contamination

The self-closing faucet will automatically turn off after a limited time, so you don't need to touch it again, which can effectively prevent your washed hands from being contaminated. This faucet is ideal if you want to maintain good hygiene standards.

2. long lasting

While regular faucets are opened and closed at least twice a day, self-closing faucets only need to be opened once. Frequent switching will make the faucet wear more seriously, so the self-closing faucet has a lower damage rate than the general faucet.

3. Effective water saving

Water only flows out during the preset time of the self-closing faucet, which greatly helps to reduce unnecessary water waste. Sometimes, some people forget to turn off the faucet after washing their hands, and the waste caused by this is incalculable. Therefore, the self-closing faucet is the perfect product for water saving and environmental protection.

4. Cost savings

When we use traditional faucets, we tend to waste more water because we let the water run longer before we wash our hands and then turn it off. If you use a self-closing faucet in your home, you can greatly reduce the amount of water you use and save on your water bills.

5. Ease of use

The biggest advantage of self-closing faucets is that the user does not need to close the faucet by himself. If you are someone who often forgets to turn off the faucet, this faucet is perfect for your home.

 

How are they maintained?

Maintenance of a self-closing faucet is no different than a standard faucet. Experts recommend cleaning once a year, and the filter element is designed to help self-clean during operation. Cleaning is considered an optional activity, but it will help prolong the life of the faucet.
