[0002] Tank valves are a common type of valve structure, generally consisting of a valve body and a valve core. While they can meet general usage requirements, their sealing performance is relatively limited, making it difficult to meet general usage needs. Furthermore, they are not conducive to regulation and control operations, thus limiting their applicability. Summary of the Invention

[0003] The purpose of this invention is to provide a sealing tank valve assembly with a reasonable structural design that is conducive to improving sealing performance.

[0004] The technical solution to achieve the purpose of this utility model is a sealed tank valve assembly, including a valve body and a valve needle disposed in the valve body. The valve body is provided with an air inlet and an air outlet, and a sealing ring groove is provided on the inner wall of the air inlet.

[0005] An air outlet connector is provided at the air outlet, and a sealing ring groove is provided on the outer wall of the air outlet connector;

[0006] An annular groove is provided on the outer wall of the valve needle;

[0007] The valve needle is disposed in the valve body and is limited by the locking nut, and a plurality of first sealing rings are provided between the valve needle and the valve body, all of which are located in the annular groove.

[0008] A second sealing ring is provided in the sealing ring groove, and the air inlet connector is sealed to the inner wall of the air inlet interface through the second sealing ring.

[0009] A third sealing ring is provided in the sealing ring groove, and the air outlet connector is sealed to the air outlet interface through the third sealing ring.

[0010] A further preferred embodiment is that a switch knob is fixed to the outer end of the valve needle, and the switch knob is provided with a rotation indicator scale.

[0011] A further preferred embodiment is that the number of the first sealing rings is two or three.

[0012] A further preferred embodiment is that the air inlet and air outlet are arranged at right angles.

[0013] This utility model has positive effects: its structure is reasonably designed, with several first sealing rings on the valve needle and the first sealing rings being limited by an annular groove. This not only improves the connection stability between the first sealing ring and the valve needle, but also improves the sealing performance between the valve needle and the valve body. At the same time, a second sealing ring is provided at the air inlet, which can improve the sealing performance of the air inlet connection. The third sealing ring can improve the sealing performance between the air outlet connector and the valve body. It is stable and reliable in use and has strong applicability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] See Figures 1 to 3 As shown, a sealed tank valve assembly includes a valve body 1 and a valve needle 2 disposed within the valve body. The valve body is provided with an air inlet 3 and an air outlet 4. A sealing ring groove 5 is provided on the inner wall of the air inlet. In this embodiment, the valve body and valve needle are conventional structures of the prior art, and are simply applied. Furthermore, the air inlet and air outlet are arranged at right angles.

[0021] In this embodiment, an air outlet connector 6 is provided at the air outlet interface, and a sealing ring groove 7 is provided on the outer wall of the air outlet connector; an annular groove 8 is provided on the outer wall of the valve needle; the air outlet connector is a conventional structure of the prior art, and is simply applied, and the width of the sealing ring groove and the annular groove can be set as needed.

[0022] During assembly, the valve needle is disposed within the valve body and limited by the locking nut 9, and a plurality of first sealing rings 10 are provided between the valve needle and the valve body, all of which are located within the annular groove; the above structure can improve the sealing performance, and in this embodiment, the number of the first sealing rings is two or three.

[0023] Meanwhile, in this embodiment, a second sealing ring 11 is provided in the sealing ring groove, and the air intake connector is sealed to the inner wall of the air intake interface through the second sealing ring; this can improve the sealing performance at the connection between the air intake connector and the air intake interface.

[0024] Furthermore, a third sealing ring is provided within the sealing ring groove, and the vent connector is sealed to the vent interface via the third sealing ring. This structure improves the sealing performance at the vent connector connection.
