Technical Field

[0001] The invention belongs to the technical field of valve cores, and more specifically, particularly relates to a coaxial three-part water thermostatic valve core. Background Art

[0002] The valve core is a valve part that the valve body uses its movement to achieve the basic functions of direction control, pressure control or flow control. Currently, it is widely used in bathroom showers and other pipes in indoor pipeline decoration. The valve core is a commonly used water flow control device in the bathroom.

[0003] When the existing valve core is used for water distribution adjustment, the valve stem rotation angle is fixed, which is inconvenient to use. After long-term use, the water flow inside the valve core may not be tightly blocked due to the fixed valve stem rotation angle, resulting in the valve core being unable to be completely closed and prone to water leakage, wasting water resources and being not practical.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a coaxial three-way water thermostatic valve core is provided, in order to achieve a more practical purpose. Summary of the invention

After long-term use, the water flow inside the valve core may not be tightly blocked due to the fixed valve stem rotation angle, which may cause the valve core to be unable to be completely closed and easily leak, thereby wasting water resources and having low practicality.

[0056] In the present invention, the hot and cold water of the device flows into the interior of the valve core housing 7 through the corresponding water inlet on the bottom side of the valve core housing 7. After the temperature of the hot and cold water is adjusted by the thermostatic valve stem 1 inside, the required water diversion port 701 is selected by rotating the water diversion valve stem 2 to flow through the static porcelain piece 401 and the dynamic porcelain piece 402 and flow out of the interior of the device from the corresponding water diversion port 701.

The device is easy to use and easy to install. When adjusting the temperature, it only needs to rotate the thermostatic valve stem 1. When the thermostatic valve stem 1 rotates, the hexagonal valve stem 3 can move up and down under the action of the top threaded rod, thereby driving the thermal sensitive element 5 to move, thereby controlling the regulator 6 to move in the internal cavity of the valve core housing 7 to change the water inlet of the hot and cold water. The gap is used to adjust the hot and cold water. When the water temperature changes, the amount of hot and cold water inlet can be automatically adjusted through the change in the elongation of the thermal sensitive element 5 to ensure the constant temperature during use. A reset top spring 601 is provided at the bottom of the valve core shell 7, so that when the device reverses the thermostatic valve stem 1, the inside of the device can automatically reset. It is convenient and flexible. When it is necessary to adjust the water flow size and the corresponding outflow water channel, it is only necessary to rotate the water diversion valve stem 2. The water diversion valve stem 2 of the device can drive the moving porcelain piece 402 to rotate 360 ​​degrees, and adopts porcelain sealing, with long service life and stable performance. The three-way water diversion and adjustment function of the water flow is realized through the overlap and blocking of the water flow on-off groove 4021 of the moving porcelain piece 402, the mixed water outlet 4011 of the static porcelain piece 401 and the water diversion outlet 701 at the bottom of the valve core shell 7. It is small in size and compact in structure, which can greatly reduce the manufacturing cost of faucet components.
