[0048] Second Embodiment

[0049] Please refer to Figure 4 and Figure 5 Another embodiment of the present utility model provides a connection system for an extended water-using element 400, including the connection valve 100 described in any one of the foregoing embodiments. The connection valve 100 is installed on a reserved main valve body 200. A water-using pipeline 300 is provided on the third fluid passage 124 of the connection valve 100. The water outlet end of the water-using pipeline 300 is connected to the second inlet 111, and a water-using element 400 is provided on the water-using pipeline 300.

[0050] In this embodiment, the connection system is applied to the extended water-using element 400. In some communities, a buried pipeline 500 is provided inside the wall 600, and a main valve is reserved outside the wall 600. As Figure 6 shown, in the prior art, if a water-using element 400 is to be installed, the wall 600 needs to be modified. In this embodiment, the connection of the extended water-using element 400 with the connection system can be carried out according to the following steps:

[0051] 1. Preliminarily assemble components such as the valve body 110, valve stem 120, and valve core 140. Remove the valve core of the reserved main valve, and then thread-connect the valve body 110 of the connection valve 100 to the main valve body 200. At the same time, a sealing valve can be placed in the third sealing groove 116 to achieve a sealed connection between the main valve body 200 and the valve body 110 of the connection valve 100;

[0052] 2. Use a wrench or other auxiliary tools to rotate the valve body 110 and adjust the relative distance between the end face of the valve body 110 and the end face of the valve stem 120, so that the sealing gasket 127 in the second sealing groove 133 is in sealed connection with the sealing surface of the valve core 140 of the original main valve;

[0053] 3. Connect the water pipeline 300 to the outlet of the third fluid passage 124, connect the water-using element 400 to the water pipeline 300, and then threadedly connect the water outlet of the water pipeline 300 to the second inlet 111 to complete the assembly of the connection system for expanding the water-using element 400.

[0054] Taking the water-using element 400 as a water purifier as an example, during specific operation, the flow rate of water in the water pipeline 300 can be adjusted by adjusting the valve core 140, and the water is introduced into the water purifier. The purified water returns from the second inlet 111 through the second fluid passage 113 to the buried pipeline 500 to provide the treated water required by the user at the end of the whole house. This embodiment can effectively ensure that users can expand the water-using element 400 without damaging the original wall 600 structure, and can also reduce the user's modification cost and pipeline risk.

[0055] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
