Single handle double control thermostatic valve

Abstract

A single-handle double-control thermostatic valve is characterized in that a valve spool is provided with a first hot water incoming passage, a first cold water incoming passage, a first hot water outgoing passage and a first cold water outgoing passage, a fixed ceramic plate is arranged over the valve spool inside a spool sleeve, a moving ceramic plate is arranged on the fixed ceramic plate, the fixed ceramic plate is provided with a second hot water incoming, a second hot water outgoing passage, a second cold water incoming passage and a second cold water outgoing passage, the second hot water incoming passage is communicated with the first hot water incoming passage of the valve spool, the second hot water outgoing passage is communicated with the first hot water outgoing passage of the valve spool, the second cold water incoming passage is communicated with the first cold water incoming passage of the valve spool, the second cold water outgoing passage is communicated with the first cold water outgoing passage of the valve spool, the moving ceramic plate is provided with a hot water control passage and a cold water control passage, the cold water control passage is capable of connecting or disconnecting the second hot water incoming passage and the second hot water outgoing passage of the fixed ceramic plate, and the cold water control passage is capable of connecting or disconnecting the second cold water incoming passage and the second cold water outgoing passage of the fixed ceramic plate. The single-handle double-control thermostatic valve has the advantages that cold water volume and hot water volume of a regulator are not changed when the moving ceramic plate rotates, the moving ceramic plate can turn off or on incoming hot or cold water by sliding, and flow is regulated.

Description

technical field [0001] The invention belongs to the technical field of plumbing equipment, in particular to a thermostatic valve used on a thermostatic faucet. Background technique [0002] Thermostatic faucets are loved by people because of their convenience in water temperature adjustment, and are more and more widely used in bathing water supply systems in various occasions. Constant temperature mainly means that users can adjust the outlet water temperature according to actual needs. After the temperature is set, the mixed outlet water temperature remains at the set temperature. The advantage of the thermostatic faucet is that it can avoid the problem of the outlet water temperature fluctuating due to the change of the inlet water pressure or the instability of the inlet water temperature of the ordinary valve core, and it is safe and anti-scalding. [0003] The thermostatic valve is a key component of the thermostatic faucet, and its function and structure directly det...

AI Technical Summary

Problems solved by technology

However, the existing single-handle thermostatic faucet can only realize the setting of the outlet water temperature and the control of the outlet water opening and closing by operating the single handle, but cannot freely adjust the outlet water flow, and cannot meet the higher needs of users.
