Description

Technical Field

[0001] The invention belongs to the technical field of thermostatic valves, and in particular relates to a large-flow detachable and washable thermostatic valve. Background Art

[0002] The thermostatic valve is a water heating device that mixes cold water and hot water to output warm water. Its core temperature control mechanism is the thermostatic valve core, which is basically composed of the main body, temperature sensing element, return spring, valve sleeve, etc. It automatically adjusts the mixing ratio of cold and hot water through the difference between the mixed water outlet temperature and the set temperature, so that the outlet water temperature is basically constant.

[0003] The common thermostatic valve, also known as the thermostatic mixing valve, generally includes an outer shell, a main valve body, a switch valve core for controlling the water volume and the switch, and a thermostatic valve core. Multiple independent water flow channels are arranged in the main valve body to supply cold, hot and mixed water. For example, the Chinese patent application number 201310489204.1 provides a dual-switch thermostatic valve, including a thermostatic valve core, a dual-switch valve core, a dual-switch knob, a temperature adjustment knob and a valve body. The valve body consists of a columnar cavity and an outer sleeve. The outer sleeve is provided with a hot and cold water inlet and a mixed water outlet, which correspond to the hot and cold water inlet area and the outlet area on the columnar cavity respectively. The thermostatic valve core and the dual-switch valve core are respectively fixed at both ends of the inner cavity of the columnar cavity. The two valve cores are respectively engaged with the thermostatic knob and the dual-switch knob for temperature adjustment and switching. The columnar cavity can introduce the hot and cold water entering the outer sleeve into the dual-switch valve core respectively, and after the switching and flow adjustment of the dual-switch valve core, they are respectively introduced into the hot and cold water inlet cavity of the thermostatic valve core, and then the mixed water is adjusted to flow out at a constant temperature by the adjustment of the thermostatic valve core.

[0004] The overall structure of the water flow channel in this type of existing constant temperature mixing valve is complex, resulting in a small aperture of the water flow channel, and thus small water inlet and output volumes, making the temperature of the output mixed water unstable, and the hot water pressure and the cold water pressure unstable, which can easily lead to large changes in the temperature of the output mixed water, making it impossible for the outlet water temperature to reach the set temperature, causing the output mixed water to easily become hot and cold, and thus the water temperature cannot be kept stable when the user is using it, causing inconvenience to the user.

[0005] In addition, the aperture of the water flow channel in the thermostatic mixing valve is small, and the water flow rate and flow rate are small, which results in slow water supply speed of solar energy or water heater and low use effect.

[0006] Moreover, the overall structure of the existing thermostatic mixing valve is an integrated design, and its switch valve core and the thermostatic valve core are fixedly installed in the thermostatic mixing valve body. Due to long-term use and water quality, scale is easily formed in the thermostatic mixing valve body, causing the thermostatic mixing valve to be blocked, greatly shortening the service life of the thermostatic mixing valve, and severely leading to thermostatic failure and the like. Moreover, after scale is formed in the thermostatic mixing valve, the released mixed water is easy to emit odor, affecting use. Summary of the invention
