Further, the jet valve is a cylindrical structure, the two ends of the jet valve are provided with external threads, the jet valves are respectively connected to the first valve body and the first valve body, the jet valve is sealed with anaerobic glue, and the front end of the jet valve is provided with A tapered via that communicates with the jet hole.

The working principle of the double-valve high-efficiency water-saving device is as follows: the double-valve high-efficiency water-saving device is installed on the faucet spout. When the faucet valve is opened, the touch-delayed self-closing type water-saving Mouth water, high-speed low-flow water outlet mode, flow rate ≤ 2L/min, daily hand washing can save more than 70% of water each time, when a large flow of water is needed, press the touch button, touch the self-closing water-saving spout, the flow rate is ≤ 9L/min, under the action of the jet valve, the spray-type water-saving nozzle stops water or a small amount of water, and it will automatically close after a delay of 10 seconds, and automatically switch to the spray-type water-saving nozzle. The water can be automatically switched to the position of the spray-type water-saving nozzle to ensure that the spray-type water-saving nozzle is the first to discharge water when the faucet is turned on.

To sum up, the double-valve high-efficiency water-saving device of the present invention has the following advantages:

1. Ensure that each time the water is used, the first is the high-speed and low-flow water outlet mode, the flow rate is ≤2L/min, and the daily hand washing can save more than 70% of water each time, which solves the problem of serious waste of hand washing water in homes and hotels, and can also take into account other large water consumption. need;

2. One faucet has two water outlet methods, with self-closing and automatic switching functions for large water volumes, saving water and metal materials, it is a real environmental protection and water-saving faucet;

3. The sealing and fastening process of the ring groove to the conical platform is not only convenient for installation, but also has a good sealing performance, and can also play a very good role in preventing theft. It cannot be disassembled without special tools.
