[0047] The embodiment provides a water inlet valve applied to a wall-mounted stove water system. Wherein, the connection relationship and working principle of the water inlet valve, the water outlet valve, the heat exchange structure and the burner of the wall-mounted stove water system are prior art, and the embodiment will not be repeated. The water inlet valve in the related art is mostly constant flow, that is, the flow size cannot be adjusted in the use process, when the external temperature is high, the temperature of the cold water entering the water inlet valve is high, so that the same gas is enough to heat the cold water to a high temperature, and the user is scalded, which affects the use experience of the user. In order to solve this problem, the water inlet valve provided by the embodiment can adjust the size of the water inlet flow to meet different temperature requirements and improve the use experience of the user.

[0048] Figure 1 A first structural schematic diagram of the water inlet valve provided by the embodiment is shown.Figure 2 A cross-sectional structure schematic diagram of the water inlet valve provided by the embodiment is shown. As shown in the figure, Figures 1-2 The water inlet valve provided by the embodiment includes a valve body 100 and a flow regulating assembly 200. The valve body 100 has a water inlet interface 111, a heat exchange inlet interface 112, a water inlet channel 1221, a water outlet channel 1222 and a first communication port 1251. One end of the water inlet channel 1221 is in communication with the water inlet interface 111. The other end of the water inlet channel 1221 can be in communication with the water outlet channel 1222 through the first communication port 1251. The water outlet channel 1222 is in communication with the heat exchange inlet interface 112. The flow regulating assembly 200 includes a servo motor 210. The output end of the servo motor 210 is provided with a blocking part 2121. The servo motor 210 is arranged on the valve body 100. The blocking part 2121 is located in the valve body 100. The servo motor 210 is configured to drive the blocking part 2121 to be close to or away from the first communication port 1251, so as to adjust the distance between the blocking part 2121 and the first communication port 1251.

[0049] The water inlet valve provided by the embodiment sets the servo motor 210 and the blocking part 2121 at the output end of the servo motor 210. When the servo motor 210 is started, the blocking part 2121 can be driven to be close to or away from the first communication port 1251, so as to adjust the distance between the blocking part 2121 and the first communication port 1251, and then adjust the water inlet flow between the water inlet channel 1221 and the water outlet channel 1222, so as to meet different water temperature requirements and improve the user experience. By using the above setting, the use of the flow limiting ring can be omitted, the material cost is reduced to a certain extent, and the water flow at the water outlet channel 1222 can be flexibly adjusted. In addition, the servo motor 210 has the advantages of high precision, stable operation, high reliability and easy maintenance, and can realize accurate adjustment of the water outlet flow in the water outlet channel 1222.

[0050] It needs to be explained that in actual use, the servo motor 210 can drive the blocking part 2121 to move between the first position and the second position. When the blocking part 2121 is located at the first position, the outer contour of the blocking part 2121 can completely cover the first communication port 1251, so that the minimum water flow through the first communication port 1251 can be close to 0, thereby increasing the adjustment interval of the water flow; when the blocking part 2121 is located at the second position, the spacing between the blocking part 2121 and the first communication port 1251 is maximum, so that the water flow through the first communication port 1251 is maximum. In the present embodiment, the servo motor 210 can drive the blocking part 2121 to move to any position between the first position and the second position, so that the water flow through the first communication port 1251 is adjusted between the minimum value and the maximum value. The present embodiment does not limit the maximum spacing between the blocking part 2121 and the first communication port 1251, and the designer can adaptively adjust it according to the model and heat exchange efficiency of the wall-hanging stove.

[0051] Figure 3 The structure schematic diagram of the second valve body 120 provided by the present embodiment is shown. Figure 4 The structure schematic diagram of the second valve body 120 provided by the present embodiment is shown. Figure 5 The structure schematic diagram of the first valve body 110 provided by the present embodiment is shown. Figures 3-5 And in combination with Figure 2 As shown, the valve body 100 includes a first valve body 110 and a second valve body 120, the first valve body 110 is provided with an inlet and outlet water interface 116, and the inlet water interface 111 and the heat exchange inlet interface 112 are both opened on the first valve body 110; the second valve body 120 includes an inlet and outlet water branch pipe 122, the inlet and outlet water branch pipe 122 is inserted into the inlet and outlet water interface 116, and the inlet and outlet water branch pipe 122 is provided with a partition 1223 along the axial direction thereof to separate the inner hole channel of the inlet and outlet water branch pipe 122 into an inlet water channel 1221 and an outlet water channel 1222. By providing the partition 1223 in the inlet and outlet water branch pipe 122, the effect of forming the spaced inlet water channel 1221 and outlet water channel 1222 in one branch pipe can be achieved, the structure is compact, and the volume of the entire inlet valve can be reduced to a certain extent.

[0052] Specifically, the first valve body 110 is further provided with a communication water cavity 117, which is in communication with the water inlet and outlet interface 116. The water inlet and outlet branch pipe 122 is inserted into the water inlet and outlet interface 116 and extends into the communication water cavity 117. The water inlet and outlet branch pipe 122 divides the communication water cavity 117 into a water inlet cavity 1171 and a water outlet cavity 1172. The water inlet cavity 1171 is in communication with the water inlet interface 111 and the water inlet channel 1221. The water outlet cavity 1172 is in communication with the water outlet channel 1222 and the heat exchange inlet interface 112. External cold water flows into the water inlet interface 111, flows to the water inlet channel 1221 through the water inlet cavity 1171, and then flows to the water outlet cavity 1172 from the water outlet channel 1222.

[0053] Optionally, the cross-sectional area of the water inlet channel 1221 is S1, and the cross-sectional area of the water outlet channel 1222 is S2, where S1 / S2<1. That is, the water flow path of the water inlet channel 1221 is smaller than that of the water outlet channel 1222, so as to reduce the water resistance in the water outlet channel 1222.

[0054] Continuing as shown in Figure 1 and Figure 2 The valve body 100 is further provided with a first water supplement channel 1211 independent of the water inlet channel 1221. One end of the first water supplement channel 1211 is in communication with the water inlet interface 111, and the other end of the first water supplement channel 1211 can be in communication with the water outlet channel 1222 through the first communication port 1251. By providing the first water supplement channel 1211, the water inlet flow of the same node can be increased, thereby improving the adjustment efficiency of the water inlet flow.

[0055] Specifically, as shown in Figure 2As shown, the external cold water flows into the water inlet interface 111 and is divided into two paths, one of which flows to the first water supplement channel 1211, and the other of which flows to the water inlet channel 1221. When the blocking part 2121 is attached to the first communication port 1251, the water in the first water supplement channel 1211 and the water inlet channel 1221 cannot flow into the water outlet channel 1222 through the first communication port 1251; when the servo motor 210 is started to drive the blocking part 2121 away from the first communication port 1251, the cold water in the first water supplement channel 1211 and the cold water in the water inlet channel 1221 can be combined in the water outlet channel 1222 through the first communication port 1251, and then flow into the water supply channel of the heat exchange structure through the heat exchange inlet interface 112, and exchange heat with the hot water in the heat exchange channel of the heat exchange structure to form warm water, and then flow to the water outlet valve, and finally flow to the bathroom pipeline from the outlet of the bathroom pipeline of the water outlet valve to provide users with domestic water. When the external temperature is high, the cold water flowing into the water inlet interface 111 has a high temperature, and the same gas can heat the water to a very high temperature. At this time, the servo motor 210 can drive the blocking part 2121 to move away from the first communication port 1251, so as to increase the distance between the blocking part 2121 and the first communication port 1251, thereby increasing the water inlet flow rate between the first water supplement channel 1211 and the water outlet channel 1222 and between the water inlet channel 1221 and the water outlet channel 1222, so as to reduce the temperature of the warm water after heat exchange by increasing the flow rate of the cold water, and avoid that the temperature of the warm water after heat exchange is too high to scald the user.

[0056] Optionally, the cross-sectional area of the first water supplement channel 1211 is S0, the cross-sectional area of the water inlet channel 1221 is S1, and the cross-sectional area of the water outlet channel 1222 is S2, wherein (S0+S1) / S2<1. That is, the sum of the water flow path of the first water supplement channel 1211 and the water flow path of the water inlet channel 1221 is less than the water flow path of the water outlet channel 1222, which can further reduce the water resistance in the water outlet channel 1222.

[0057] As shown in FIG. 1, the first valve body 110 is provided with a water inlet interface 111, a water outlet interface 112, and a water inlet and outlet branch pipe 122. The water inlet interface 111 is connected to the water inlet branch pipe 122, and the water outlet interface 112 is connected to the water outlet branch pipe 122. The water inlet and outlet branch pipe 122 is provided with a water inlet channel 1221 and a water outlet channel 1222. The water inlet channel 1221 is connected to the water inlet interface 111, and the water outlet channel 1222 is connected to the water outlet interface 112. Figures 2-5 As shown, the second valve body 120 further comprises a water supplement branch pipe 121, which is arranged in parallel and spaced apart with the water inlet and outlet branch pipe 122. The first valve body 110 is further provided with a water supplement interface 115, and the water supplement branch pipe 121 is inserted into the water supplement interface 115 and connected to the water inlet cavity 1171. The first water supplement channel 1211 is formed in the water supplement branch pipe 121. The cold water flowing into the water inlet cavity 1171 from the water inlet interface 111 can flow into the first water supplement channel 1211 and the water inlet channel 1221 at the same time.

[0058] Optionally, the second valve body 120 further comprises a main valve part 125, the water supplement branch pipe 121 and the water inlet and outlet branch pipe 122 are connected to the main valve part 125, and the flow adjusting assembly 200 is installed on the main valve part 125. By arranging the main valve part 125, the overall support of the water supplement branch pipe 121 and the water inlet and outlet branch pipe 122 can be realized, so as to ensure the integrity of the second valve body 120.

[0059] The water inlet valve provided by the embodiment further comprises a manual water supplement valve 300, the valve body 100 further has a second water supplement channel 1241, a second communication opening 1240 and a water pump interface 114, one end of the second water supplement channel 1241 can be communicated with the first water supplement channel 1211 through the second communication opening 1240, and the other end of the second water supplement channel 1241 is communicated with the water pump interface 114; the manual water supplement valve 300 is adjustably installed on the valve body 100 and can selectively block the second communication opening 1240. When the heating water circuit is short of water, the manual water supplement valve 300 can be adjusted to open the second communication opening 1240, so that the water in the first water supplement channel 1211 flows to the water pump interface 114 through the second communication opening 1240 and the second water supplement channel 1241, and is delivered to the wall-hanging stove for heating to supplement the water of the heating water circuit. The specific structure and working principle of the manual water supplement valve 300 are not limited in the embodiment, and the manual water supplement valve capable of being applied to the water inlet valve in the prior art is within the protection scope of the embodiment.

[0060] Specifically, the second valve body 120 further comprises an outer ring branch pipe 124, the outer ring branch pipe 124 is annularly arranged at the outer periphery of the water supplement branch pipe 121, and the interval between the two forms the second water supplement channel 1241; wherein the water pump interface 114 is arranged on the first valve body 110.

[0061] Optionally, the second valve body 120 further comprises an installation branch pipe 123, the installation branch pipe 123 is connected to the main valve part 125, and the installation branch pipe 123 is provided with an installation cavity, and the manual water supplement valve 300 is partially installed in the installation cavity to realize the stable installation of the manual water supplement valve 300.

[0062] Figure 6 A sectional structure schematic view of the flow adjusting assembly 200 provided by the embodiment is shown. As shown in the figure, Figure 6 and combined with Figures 2-4As shown, the servo motor 210 comprises a motor body 211 and a regulating valve core 212 connected with the motor body 211, and a side wall portion of the regulating valve core 212 is outwardly convex to form an upper blocking portion 2121. Further, the valve body 100 is further provided with a mounting port 1253 for mounting the flow regulating assembly 200, and the flow regulating assembly 200 further comprises a support sleeve 220 which is sealingly connected to the mounting port 1253, and the regulating valve core 212 is arranged in the support sleeve 220 and threadedly connected with the support sleeve 220. When the motor body 211 is started, it can drive the regulating valve core 212 to rotate, thereby driving the blocking portion 2121 to move along the axial direction of the regulating valve core 212 to approach or move away from the first communication port 1251. By arranging the support sleeve 220, the transmission support of the regulating valve core 212 can be increased. In the embodiment, the mounting port 1253 is arranged at the end of the main valve portion 125 away from the water replenishing branch pipe 121, and the first communication port 1251 is a sealing step arranged on the inner wall of the mounting port 1253.

In the embodiment, the first sealing member 231 and the second sealing member 232 can both be O-shaped sealing rings, and the number of layers of the O-shaped sealing rings is not limited; for example, the first sealing member 231 can be selected to be arranged in one layer, two layers, three layers or even more layers.

[0064] It should be explained that when the blocking portion 2121 is located at the second position, the blocking portion 2121 abuts against the support sleeve 220 to limit the maximum opening degree of the blocking portion 2121 by the position of the support sleeve 220, thereby facilitating the determination of the maximum value of the water flow. When designing the water inlet valve, the maximum opening degree of the blocking portion 2121 can be changed by changing the length of the part of the support sleeve 220 for abutting against the blocking portion 2121, thereby changing the regulating range of the regulating water flow.
