Description

Technical Field

[0001] The utility model relates to the field of constant temperature and constant pressure valves, in particular to a corrosion-resistant constant temperature and constant pressure valve. Background Art

[0002] Thermostatic valves are popular among people because of their convenient water temperature adjustment. They are being used more and more widely in bathing water supply systems in various occasions. Constant temperature mainly means that users can adjust the water outlet temperature according to actual needs. After the temperature is set, the mixed water outlet temperature is maintained at the set temperature. The advantage of a thermostatic faucet is that it can avoid the problem of hot and cold water outlet temperature caused by changes in water inlet pressure or unstable water inlet temperature of ordinary valve cores. It is safe and scalding-proof. The existing constant temperature and pressure valves have poor corrosion resistance, and the fluid contains some impurities, which is inconvenient to filter and affects use, bringing certain adverse effects to people's use process. For this reason, we propose a corrosion-resistant constant temperature and pressure valve. Utility Model Content
