[0036] Figure 1 The structure schematic diagram of the one-way assembly 100 provided by the embodiment is shown. Figure 2 The cross-sectional schematic diagram of the one-way assembly 100 provided by the embodiment is shown. As shown inFigures 1-2 As shown, the bypass structure provided by the embodiment includes a valve body and a one-way assembly 100, the valve body has a valve cavity therein, and one end of the valve body is provided with a mounting port in communication with the valve cavity; the one-way assembly 100 includes a one-way valve 1 and an integrally formed mounting piece 2, the mounting piece 2 includes a valve seat 21 and a blocking part 22 connected together, the valve seat 21 is installed in the valve cavity and separates the valve cavity to form a liquid inlet cavity and a liquid outlet cavity, the valve seat 21 is provided with a valve port 211 capable of communicating the liquid inlet cavity and the liquid outlet cavity, and the one-way valve 1 is adjustably arranged on the valve seat 21 to selectively block the valve port 211; and the blocking part 22 blocks the mounting port.

[0037] The bypass structure provided by the embodiment can facilitate the machining of the valve cavity in the valve body by providing the mounting port on the valve body, so as to simplify the machining process and reduce the machining difficulty; the mounting piece 2 is provided in an integrally formed structure, when the one-way valve 1 is installed in the valve body, the operator can hold the blocking part 22 and make the valve seat 21 align with the mounting port and be inserted into the valve cavity, so as to realize the quick installation of the one-way valve 1 on the valve body, and the installation efficiency is high; the blocking part 22 blocks the mounting port, so as to avoid the liquid in the valve cavity from leaking from the mounting port, thereby ensuring the use safety of the bypass structure.

[0038] It should be particularly pointed out that the bypass structure provided by the embodiment is mainly applied to a water outlet valve, wherein the above-mentioned “valve body” specifically refers to a bypass valve part of the water outlet valve, and the “valve cavity of the valve body” specifically refers to a bypass flow channel provided in the bypass valve part, and the one-way assembly 100 is arranged in the bypass flow channel, so as to timely supplement water to the heating waterway when the heating waterway is short of water, thereby stabilizing the water pressure balance of the whole wall-mounted stove waterway system, and further ensuring the safe use of the wall-mounted stove waterway system. Of course, in other embodiments, the bypass structure can also be used in other valve structures which need to realize the one-way flow of the internal liquid, which is not limited herein.

[0039] In order to further avoid the water in the valve cavity from leaking from the gap between the blocking part 22 and the mounting port, a second sealing member (not shown in the figure) is arranged between the blocking part 22 and the mounting port. In the embodiment, a second accommodating groove 221 for accommodating the second sealing member is arranged on the outer wall of the blocking part 22, so as to realize the stable installation of the second sealing member and avoid its displacement or falling off in the use process. Of course, in other embodiments, the second accommodating groove 221 can also be arranged on the inner wall of the mounting port, which can also realize the above-mentioned effect.

[0040] Optionally, the second sealing member can be an O-ring or a star-shaped ring. In addition, the number of the second sealing member is not limited in the embodiment, which can be at least two, and the at least two second sealing members are arranged in the axial direction of the blocking part 22, so as to improve the sealing effect.

[0041] As shown in the figure, Figure 2As shown, the one-way valve 1 includes a valve core 11 and a spring 12. The valve core 11 is movably mounted on the valve seat 21. The two ends of the spring 12 are connected to the valve core 11 and the valve seat 21, respectively. The valve core 11 can press against the valve port 211 under the elastic action of the spring 12. Optionally, a sealing gasket 13 is also provided on the side of the valve core 11 facing the valve port 211 to improve the sealing performance of the valve core 11 in the sealed position. The one-way valve is a commonly used valve structure in the prior art, and the working principle of the one-way valve will not be described in detail in this embodiment.

[0042] like Figure 1 and Figure 2 As shown, the one-way assembly 100 also includes a connecting rib 23, with its two ends connected to the valve seat 21 and the sealing part 22, respectively. The connecting rib 23 extends the overall length of the one-way assembly 100 to match the valve body with a longer valve cavity, thereby improving the versatility of the bypass structure.

[0043] In this embodiment, there are two connecting ribs 23, which are symmetrically arranged on both sides of the sealing part 22. The gap between the two connecting ribs 23 allows water in the valve cavity to pass through. This arrangement can improve the stability of the connection between the sealing part 22 and the valve seat 21 without affecting the water flow rate in the valve cavity. Of course, in other embodiments, the number of connecting ribs 23 can be adjusted according to the actual situation, and this embodiment does not limit this.

[0044] Optionally, a first sealing element 3 is provided between the valve seat 21 and the cavity wall of the valve chamber to ensure the sealing between the mounting part 2 and the valve body 1, preventing water in the valve chamber from passing through the gap between the mounting part 2 and the valve body 1 and affecting the performance of the bypass structure. In this embodiment, a first receiving groove 212 for accommodating the first sealing element 3 is provided on the outer wall of the valve seat 21 to achieve stable installation of the first sealing element 3 and prevent it from shifting or falling off during use. Of course, in other embodiments, the first receiving groove 212 can also be provided on the cavity wall of the valve chamber, which can achieve the same effect.

[0045] Optionally, the first sealing element 3 can be an O-ring or a star-shaped ring. Furthermore, this embodiment does not limit the number of first sealing elements 3; there can be at least two, and these at least two first sealing elements 3 are spaced apart along the axial direction of the valve seat 21 to improve the sealing effect.

[0046] Continue as Figure 1 and Figure 2 As shown, the mounting component 2 also includes a latch 24, which is disposed on the sealing part 22. When the sealing part 22 seals the mounting opening, the latch 24 engages with the side wall of the valve body. By providing the latch 24, the stability of the connection between the mounting component 2 and the valve body can be improved, so as to prevent the mounting component 2 from falling off the valve body during use and causing a safety accident.

[0047] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the above examples do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
