The water valve cartridge 2 of the thermostatic valve 100 according to the embodiment of the present invention is described in detail below with reference to fig. 1 and 2.
According to some embodiments of the invention, as shown in fig. 1 and 2, the water valve core 2 comprises: a water flow regulating ring 21, a water flow regulating rod 22, an elastic diaphragm 23 and a regulating spring 24.
Specifically, as shown in fig. 2, a water flow rate adjusting ring 21 may be provided on the valve body 1, and the water flow rate adjusting ring 21 may be located in the water passage 10a, and the water flow rate adjusting ring 21 may constitute a water flow rate adjusting hole 210 located between the water inlet 101 and the water outlet 102. The water flow adjusting rod 22 can be movably matched with the water flow adjusting ring 21 to adjust the opening of the water flow adjusting hole 210, so as to realize the adjustment of water inflow. An elastic diaphragm 23 may be provided in the water passage 10a, and the elastic diaphragm 23 may be connected to the linkage assembly 4 and the water flow rate adjusting lever 22, respectively. The elastic diaphragm 23 has elastic properties, can be elastically deformed when subjected to a force, and the elastic diaphragm 23 has a characteristic of being able to recover. The adjusting spring 24 is compressed between the water flow adjusting ring 21 and the water flow adjusting rod 22. The adjustment spring 24 may normally urge the elastic diaphragm 32 away from the water flow adjustment lever 22 to resiliently urge the linkage assembly 4.
In this way, when the water flow rate is increased or the external water pressure is increased by a user, the pressure borne by the elastic diaphragm 23 is increased, at the moment, the elastic diaphragm 23 is elastically deformed to move leftwards, and under the combined action of the elastic diaphragm 23 and the adjusting spring 24, the linkage assembly 4 moves leftwards to drive the air valve core 3 to move leftwards so as to increase the opening of the air passing channel 10b, so that the air inflow is increased, and the air inflow is increased along with the increase of the water inflow; when the water flow rate or the water pressure of a user is reduced, the pressure borne by the elastic diaphragm 23 is reduced, at the moment, the elastic diaphragm 23 is restored, and under the combined action of the elastic diaphragm 23 and the regulating spring 24, the linkage assembly 4 moves rightwards to drive the air valve core 3 to move rightwards so as to reduce the opening of the air passing channel 10b, thereby reducing the air inflow, and reducing the air inflow along with the reduction of the water inflow. The synchronous increase and the synchronous decrease of the gas flow and the water flow or the water pressure are realized, and the temperature of the discharged water tends to be constant.
The water flow adjusting lever 22 is provided with an adjusting portion (not shown) extending out of the air passage 10b, and a user can adjust the distance between the water flow adjusting lever 22 and the water flow adjusting ring 21 by adjusting the adjusting portion, thereby adjusting the opening of the water flow adjusting hole 210 and further adjusting the water flow.
For example, as shown in fig. 2, the water flow rate adjusting rod 22 penetrates the water flow rate adjusting ring 21, and the outer peripheral surface of the right end of the water flow rate adjusting rod 22 protrudes inward and leftward, so that the outer peripheral surface of the water flow rate adjusting rod 22 abuts against the inner peripheral surface of the water flow rate adjusting ring 21. When the water flow regulating rod 22 moves leftwards in the water flow regulating ring 21, the opening of the water flow regulating ring 21 can be reduced, and the water flow is reduced; when the water flow rate adjusting lever 22 moves rightward in the water flow rate adjusting ring 21, the opening degree of the water flow rate adjusting hole 210 can be increased, and the water flow rate can be increased.
The air valve core 3 of the thermostatic valve 100 according to the embodiment of the present invention is described in detail below with reference to fig. 1 and 3.
According to some embodiments of the present invention, as shown in fig. 1 and 3, the valve body 1 may be configured with an actuating hole 12, and the air valve core 3 includes: the air flow adjusting lever 31, the diaphragm 32 and the feedback spring 33, wherein the air flow adjusting lever 31 may be provided with an air flow adjusting hole 310 located between the air inlet 103 and the air outlet 104, the air flow adjusting hole 310 may movably pass through the actuating hole 12, and the air flow adjusting hole 310 may be stopped at the edge of the actuating hole 12, and the air flow adjusting lever 31 may adjust the opening degree of the air flow adjusting hole 310 by the acting force of the edge of the actuating hole 12.
The diaphragm 32 can be arranged in the air passage 10b, and the diaphragm 32 can be respectively connected with the linkage assembly 4 and the air flow adjusting rod 31 so as to drive the air flow adjusting rod 31 to move when the linkage assembly 4 moves, thereby realizing synchronous adjustment of air flow along with water flow and being beneficial to realizing constant temperature of water outlet.
The feedback spring 33 may be provided between the valve body 1 and the flow adjustment lever, and the linkage assembly 4 is located at both sides of the flow adjustment lever 31, respectively. In this way, the feedback spring 33 can be normally stopped against the air flow adjusting rod 31 to move towards the linkage assembly 4, so that the air flow adjusting rod 31 has a trend of normally closing the air flow adjusting hole 310, and the synchronous adjusting function of the linkage assembly 4 is more sensitive and reliable.
Alternatively, the air flow adjusting lever 31 may be provided with the air valve 34 normally stopped on the edge of the actuation hole 12, and the surface of the air valve 34 normally stopped on the edge of the actuation hole 12 may be configured as an arc-shaped surface 341 protruding toward the actuation hole 12. For example, in the example shown in fig. 3, the air flow adjusting lever 31 is provided with the air valve 34, the air valve 34 can adjust the air flow opening, the right side surface of the air valve 34 is always abutted against the edge of the actuating hole 12, and the right side surface of the air valve 34 is configured as an arc surface 341 protruding rightward.
Therefore, when the water flow rate is increased or the water pressure is increased, the water valve core 2 drives the linkage assembly 4 to move leftwards, the linkage assembly 4 drives the air flow adjusting rod 31 to move leftwards, the air valve 34 moves leftwards under the combined action of the air flow adjusting rod 31 and the feedback spring 33, and therefore the air flow opening is increased; when the book flow is reduced or the water pressure is reduced, the water valve core 2 can drive the linkage assembly 4 to move rightwards, the linkage assembly 4 drives the air flow adjusting rod 31 to move rightwards, the air valve 34 moves rightwards under the combined action of the air flow adjusting rod 31 and the feedback spring 33, and accordingly the air flow opening is reduced. In short, the valve 34 can realize the adjustment of the opening of the overair passage 10b along with the air valve core 3 under the combined action of the water valve core 2 and the feedback spring 33.
When the gas pressure of the gas inlet 103 increases, a pressure difference occurs at two sides of the diaphragm 32, the diaphragm 32 is subjected to a rightward acting force, and the diaphragm 32 moves a small distance rightward, so that the diaphragm 32 drives the gas flow adjusting rod 31 and the gas valve 34 to move rightward, and the gas flow opening is slightly reduced; conversely, when the gas pressure of the gas inlet 103 decreases, a pressure difference occurs at both sides of the diaphragm 32, the diaphragm 32 receives a leftward force, and the diaphragm 32 moves a slight distance leftward, so that the diaphragm 32 drives the gas flow adjusting lever 31 and the valve 34 to move leftward, so that the gas flow opening slightly increases. Therefore, the air flow opening can be dynamically controlled along with the change of air pressure, the pressure stabilizing effect is realized, the constant temperature of the water outlet can be further realized, and the water use comfort level is improved.
