Description

Technical Field

[0001] This application relates to the field of water outlet valves, and in particular to a plastic water outlet valve. Background Technology

[0002] The outlet valve is used to control the location where water flows out and whether water flows out.

[0003] Currently, the water outlet control of gas water heaters mainly relies on the outlet valve. Existing outlet valves all have heating water entering from the side. This traditional side-entry structure greatly limits the technical structure of the valve body, making the valve body relatively bulky. There are relatively few technical structures that can be installed on the valve body within the limited space, which cannot meet the valve body's requirements for real-time acquisition of various technical information such as water pressure and flow rate. How to optimize the valve body structure has always been the research object of those skilled in the art. Utility Model Content

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0029] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0030] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] Reference Figure 1-6 A plastic water outlet valve includes a valve body 1 and a connector; both the valve body 1 and the connector are made of one piece of plastic. The valve body 1 has a water inlet 2, a heating outlet 3, a hot water exchange inlet 4, a hot water exchange outlet 5, and a bathroom hot water outlet 6. The hot water exchange inlet 4 and the hot water exchange outlet 5 are connected via a plate heat exchanger; the hot water exchange outlet 5 and the bathroom hot water outlet 6 are connected via the connector.

[0032] The heating outlet 3 and the bathroom hot water outlet 6 are set in parallel.

[0033] The heating outlet 3 and the hot water inlet 4 are set vertically.

[0034] The connector includes a connecting part 7 and a connecting plate 8. The connecting part 7 is fixedly mounted on the valve body 1, and the connecting part 7 and the valve body 1 can be integrally formed. The connecting plate 8 covers the connecting part 7, and the connecting plate 8 and the connecting part 7 are connected by bolts. The connecting part 7 is recessed inward to form a cavity 9, and the two ends of the cavity 9 are respectively connected to the hot water outlet 5 and the bathroom hot water outlet 6. The connector also includes a sealing ring 10. The connecting part 7 has a groove 11, and the sealing ring 10 is embedded in the groove 11. The connecting plate 8 has a connecting post 12, and the connecting post 12 has a through hole 13, which is connected to the hot water outlet 5.

[0035] A first limiting rod 14 is provided on one end of the connecting part 7, and a first limiting groove 15 that cooperates with the first limiting rod 14 is provided on the connecting plate 8. A second limiting rod 16 is provided on the other end of the connecting part 7, and a second limiting groove 17 that cooperates with the second limiting rod 16 is provided on the connecting plate 8. The width of the second limiting rod 16 is smaller than the width of the first limiting rod 14.

[0036] The valve body 1 has a switching cavity 18, one end of which is connected to the water inlet 2, and the other end is connected to the hot water inlet 4. The valve body 1 also has a connecting cavity 19, which is located on the side away from the hot water inlet 4. The switching cavity 18 is connected to the heating outlet 3 through the connecting cavity 19. This greatly reduces the size of the valve body 1 and allows for the installation of more technical structures within a limited space.

[0037] The lower end of the connecting cavity 19 is connected to the heating outlet 3 through the heating cavity 20.

[0038] The upper end of the connecting cavity 19 is connected to the water inlet 2 through the switching passage 18. The connecting cavity 19 itself is not directly connected to the water inlet 2, and the water inlet 2 is not directly connected to the heating outlet 3, thereby avoiding water flowing directly into the heating outlet 3 and causing water pressure problems.

[0039] The valve body 1 is also equipped with a switching device, which is located in the switching passage 18. The switching device switches the water inlet 2 to connect to the connecting chamber 19 or the hot water inlet 4.

[0040] The switching device includes a motor 21 and a ball valve 22. The ball valve 22 is located in the switching passage 18 and is mounted on the transmission rod of the motor 21. The motor 21 drives the ball valve 22 to move, thereby switching the connection state between the connecting chamber 19, the hot water inlet 4, and the inlet hole 2.

[0041] In the description of the embodiments of this application, it should be noted that the terms "inner" and "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0042] In the description of this application, the references to terms such as "an embodiment," "some embodiments," "in this embodiment," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application.
