A single-handle thermostatic water valve and its applied faucet

Abstract

The invention discloses a single-handle constant-temperature water valve. The single-handle constant-temperature water valve comprises an upper shell, a lower shell, a ceramic valve core, a valve core seat, a temperature sensing rod, a stud, a piston, a buffering assembly, a returning spring and a water isolation jacket, wherein the ceramic valve core has a switch function; the lower shell is sleeved with the upper shell; a hot water inlet is formed in the bottom of the lower shell; a cold water inlet is formed in the upper end of the lower shell; the water isolation jacket is fixed at the lower end of the lower shell; the lower end of the piston is sleeved into the upper end of the lower shell; the lower end of the returning spring is pressed into the bottom of the water isolation jacket; the buffering assembly is mounted between the piston and the returning spring; the lower end of the temperature sensing rod extends between the piston and the lower shell and is also connected with an ejector rod; the ejector rod stretches into the piston and presses against the buffering assembly; the upper end of the buffering assembly is clamped with the piston; the lower end of the buffering assembly elastically presses against the returning spring. The single-handle constant-temperature water valve is simple in structure and is capable of simultaneously regulating temperature and flow of the water.

Description

technical field [0001] The invention relates to a constant temperature water valve structure, in particular to a single-handle constant temperature water valve and a faucet for its application. Background technique [0002] Existing thermostatic water valves can only adjust the temperature of the outlet water. When used on a thermostatic faucet, additional switch valve cores and handles are required. In fact, two handles control the water temperature and flow rate respectively, resulting in a more complicated structure and a larger volume of the thermostatic faucet. Larger and more expensive. [0003] In order to overcome the above-mentioned shortcoming, the inventor specially developed a kind of single-handle thermostatic water valve with simple structure, and this case arises from it. Contents of the invention [0004] The main purpose of the present invention is to provide a single-handle thermostatic water valve, which has a simple structure and realizes the adjustmen...
