[0033] This utility model provides a valve body 100 installed on a wall-hung boiler water valve. Specifically, the water valve is a wall-hung boiler inlet valve, comprising a valve body 200 and a valve body 100, wherein the valve body 100 is detachably installed on the valve body 200. In the art, the connection methods for integrating other valve bodies 100 onto the valve body 200 of the inlet valve include threaded connection, integral molding, and pin connection. If multiple water passage joints on other valve bodies 100 need to be connected to the valve body 200, in order to ensure the stability of the connection, detachable fixing structures such as pins are required for auxiliary connection at each water passage joint, resulting in material waste.

[0034] Reference Figures 1-3In an embodiment of this utility model, the valve body 100 includes an inlet / outlet water pipe 11. Simultaneously, a water supply valve 12 is integrated on the valve body 100. The water supply valve 12 includes an inlet branch pipe 13. The water valve body 200 is provided with a first mounting port 21 and a second mounting port 22. The first mounting port 21 is configured as a plug-in slot adapted to the outer contour of the inlet / outlet water pipe 11. When the valve body 100 is installed on the water valve body 200, the inlet / outlet water pipe 11 is aligned and inserted into the plug-in slot, and the inlet branch pipe 13 is aligned and inserted into the second mounting port 22. Then, the inlet branch pipe 13 and the second mounting port 22 are connected by a pin connection to achieve a detachable connection between the valve body 100 and the water valve body 200. With this design, even though the valve body 100 has two water connectors, the connection between the entire valve body 100 and the water valve body 200 can be achieved by using a pin connection only at the connection between the water inlet branch pipe 13 and the second mounting port 22, saving materials and assembly time.

[0035] In the embodiments of this utility model, the first mounting port 21 and the second mounting port 22 are arranged independently and in parallel; the inlet and outlet water pipes 11 and the inlet branch pipe 13 are arranged independently and in parallel, which is conducive to the smooth insertion of the valve body 100 and the water valve body 200 during connection.

[0036] In an embodiment of this utility model, the water inlet branch pipe 13 is inserted into the second mounting port 22, and a pin slot is correspondingly opened on the water inlet branch pipe 13 and the second mounting port 22. The pin slot is used to insert a pin so as to fix the valve body 100 on the water valve body 200.

[0037] In the embodiments of this utility model, in order to enhance the sealing effect, sealing elements, such as sealing rings, should be provided between the first mounting port 21 and the inlet / outlet pipe 11, and between the inlet branch pipe 13 and the second mounting port 22. Furthermore, in order to improve the stability of the connection, the length of the inlet / outlet pipe 11 needs to be longer, and the depth of the insertion groove should be deep enough to ensure that the inlet / outlet pipe 11 can be smoothly inserted during installation and to meet the sealing requirements during use.

[0038] In an embodiment of this utility model, a partition is provided inside the inlet and outlet water pipe 11 to separate the inlet and outlet water pipe 11 into a first inlet and outlet water channel 111 and a second inlet and outlet water channel 112. A connecting cavity 14 is provided inside the valve body 100. The first inlet and outlet water channel 111 and the second inlet and outlet water channel 112 are connected through the connecting cavity 14. The water inlet branch pipe 13 is also connected to the connecting cavity 14. The internal channel in the water inlet branch pipe 13 is the water replenishment inlet 131, so the water replenishment inlet 131 is connected to the connecting cavity 14.

[0039] In an embodiment of this utility model, the first inlet / outlet channel 111 serves as the inlet channel, and the second inlet / outlet channel 112 serves as the outlet channel. The diameter of the first inlet / outlet channel 111 is smaller than that of the second inlet / outlet channel 112.

[0040] In the embodiments of this utility model, the cross-sectional area of ​​the internal channel (water supply inlet 131) of the water inlet branch pipe 13 is S0, the cross-sectional area of ​​the first water inlet / outlet channel 111 is S1, and the cross-sectional area of ​​the second water inlet / outlet channel 112 is S2, wherein (S0+S1) / S2<1. Under the condition that the water inlet diameter is smaller than the water outlet diameter, the purpose of reducing water resistance can be achieved.

[0041] In an embodiment of this utility model, the valve body 100 includes an installation branch pipe 16, and an installation cavity 161 is provided inside the installation branch pipe 16. The water supply valve 12 is installed in the installation cavity 161. The specific structure and working principle of the water supply valve 12 are all existing technologies and can be clearly understood with reference to the accompanying drawings, so they will not be described in detail here.

[0042] In an embodiment of this utility model, the valve body 100 further includes an outer ring branch pipe 17 surrounding the water inlet branch pipe 13, forming an outer ring channel 171 between the outer ring branch pipe 17 and the water inlet branch pipe 13; the mounting cavity 161 is directly connected to the outer ring channel 171, and the mounting cavity 161 is connected to the connecting cavity 14 through a connecting hole 162, and the water supply valve 12 is used to selectively block the connecting hole 162.

[0043] Reference Figures 1-4 In an embodiment of this utility model, the water valve body 200 is provided with a water pump interface 23 and a third channel 24. After the valve body 100 is installed on the water valve body 200, the outer ring channel 171 and the third channel 24 together form a water replenishment channel. The water pump interface 23 is connected to the water replenishment channel, and the third channel 24 is connected to the outer ring channel 171 and the water pump interface 23.

[0044] The process of using the inlet valve in this embodiment to replenish heating water is as follows: By turning the handle of the water replenishment valve 12, the connecting hole 162 is opened. At this time, the water replenishment channel is connected to the connecting cavity 14 through the connecting hole 162. The water in the connecting cavity 14 flows into the water replenishment channel through the connecting hole 162, and then flows to the water pump interface 23. The water is then pumped to the wall-mounted boiler for heating, thus replenishing the heating water circuit.

[0045] In an embodiment of this utility model, a drive component mounting port 15 is provided on the valve body 100. The drive component mounting port 15 is used to install a drive component to adjust the opening of the connecting cavity 14, so that after the valve body 100 is installed on the water valve body 200, the purpose of adjusting the inlet and outlet water flow rate can be achieved by the drive component.

[0046] In embodiments of this utility model, the drive component mounting port 15 can accommodate at least the installation of a servo motor and a solenoid valve, allowing the same valve body 100 to accommodate two different drive components, thereby saving manufacturing costs. Figure 5 , Figure 6 The diagram shown is a schematic of the device after installing a solenoid valve as the driving component; as shown Figure 7 , Figure 8 The diagram shown is a schematic of the device after a servo motor has been installed as a drive component.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
