[0032] In this embodiment, an embedded gas valve is proposed, which has a simple structure and low cost, and the embedded gas valve is installed on the table of the reference body in a simple and convenient manner, thereby improving the installation efficiency of the embedded gas valve. The reference body specifically refers to a wall, a table or a cabinet, and correspondingly, the table of the reference body specifically refers to a wall, a table or a cabinet. The specific structure of the reference body is not limited here, and needs to be determined according to actual installation requirements and specific working conditions.

[0033] Specifically, Figure 1 As shown, the embedded gas valve includes a mounting box and a gas valve body 2; wherein the mounting box includes a panel 1 and a box body 4 connected to each other, and an accommodating cavity 7 is formed between the panel 1 and the box body 4; the gas valve body 2 includes a valve body 21, a valve stem 22 and a knob 3, one end of the valve stem 22 is connected to the valve body 21, and the other end of the valve stem 22 is connected to the knob 3, the knob 3 is exposed on the panel 1, the valve body 21 is installed in the accommodating cavity 7, and the valve body 21 is fixedly installed on the panel 1.

[0034] Compared with the prior art, the embedded gas valve in this embodiment adopts the panel 1 to position the valve body 21, eliminating the lifting structure in the prior art; by fixing the valve body 21 to the panel 1, when the panel 1 is installed as the installation reference surface, the fixed connection between the panel 1 and the valve body 21 can provide a positioning effect for the valve body 21, so that the panel 1 also has a positioning effect on the valve stem 22 connected to the valve body 21, thereby ensuring that the knob 3 connected to the valve stem 22 can be positioned outside the panel 1, so that the knob 3 can always be exposed to the panel 1, so as to ensure that the valve body 21 is fixed to the panel 1. It is convenient to manually turn the knob 3; the valve body 21 is positioned by connecting the panel 1 and the valve body 21, so that the knob 3 can be positioned to ensure that the knob 3 can always be exposed to the panel 1 during the installation of the panel 1. There is no need to additionally set a lifting structure to lift and adjust the height of the valve body 21 to ensure that the knob 3 is always exposed to the panel 1. The lifting structure is omitted, so that the structure of the entire embedded gas valve is simpler and the cost is lower, and the installation method of the embedded gas valve can be simple and convenient, saving time and effort.

[0035] Furthermore, by providing the box body 4, on the one hand, the box body 4 can provide protection for the gas valve body 2, so as to better protect the entire gas valve body 2; on the other hand, the gas valve body 2 can be first installed in the box body 4, and then the entire box body 4 can be installed in the reference body, so as to facilitate the installation of the gas valve body 2 in the reference body, making the installation of the gas valve body 2 simpler and more convenient, thereby further improving the installation efficiency of the entire embedded gas valve.

[0036] Specifically, an installation slot is provided in the reference body, the box body 4 is installed in the installation slot, the pipeline is pre-buried in the reference body, and then the gas valve body 2 is installed in the box body 4, so as to effectively provide protection for the gas valve body 2 and prevent safety problems caused by accidental touching of the gas valve body 2, thereby ensuring that the entire embedded gas valve is highly safe to use.

[0037] Specifically, when the panel 1 is installed on the table top of the reference body, the panel 1 is not lower than the table top, that is, the panel 1 can be flush with the table top, or it can be protruded from the table top to facilitate the screwing of the knob part 31 located outside the panel 1, thereby avoiding interference of the reference body or the panel 1 with the screwing of the knob 3.

[0038] Furthermore, the panel 1 can be installed in a liftable manner on the box body 4 to adjust the height between the box body 4 and the panel 1, thereby adjusting the cavity height of the accommodating cavity 7, so that valve bodies 21 of various sizes can be installed in the accommodating cavity 7, thereby ensuring that the embedded gas valve has good applicability and versatility.

[0039] Specifically, if Figure 1 As shown, the panel 1 is installed on the box body 4 in a liftable manner through the connecting bolts 6 , that is, the lifting height of the panel 1 relative to the box body 4 can be adjusted by screwing the connecting bolts 6 .

[0040] Furthermore, if Figures 1 to 4 As shown, the panel 1 and the valve body 21 are fixed to each other via a connecting assembly, one end of the connecting assembly is fixed to the panel 1 , and the other end of the connecting assembly is fixed to the valve body 21 .

In this embodiment, the connection assembly includes three connection columns 12 and three screws 13.

[0045] In other embodiments, Figure 3 and Figure 4 As shown, the connection assembly includes a mounting rod 14 and an arc clamp 15 fixed to the mounting rod 14, one end of the mounting rod 14 is fixed to the recessed portion 11, and the arc clamp 15 matches the outer circumferential surface of the valve body 21, so that the arc clamp 15 is used to annularly clamp to the outer circumferential surface of the valve body 21, thereby realizing the clamp connection between the connection assembly and the valve body 21. In this embodiment, three mounting rods 14 and three arc clamps 15 are respectively provided, so that the three arc clamps 15 can be simultaneously annularly clamped to the outer circumferential surface of the valve body 21, thereby ensuring the stability and reliability of the connection between the connection assembly and the valve body 21.

[0047] It is worth noting that the connection component can also be other connection structures. Here, the specific structure of the connection component is not limited, as long as the panel 1 and the valve body 21 can be fixed to each other through the connection component.

[0048] Furthermore, if Figure 1 As shown, the installation box further includes a cover plate 5 , which is detachably covered on the panel 1 , and a protective cavity 51 is formed between the panel 1 and the cover plate 5 , and the knob 3 is located in the protective cavity 51 .

[0049] By setting the cover plate 5, the cover plate 5 is matched with the panel 1 to cover the knob 3 in the protective cavity 51; on the one hand, the cover plate 5 can provide protection for the knob 3 and better protect the knob 3; on the other hand, it can avoid safety problems caused by accidental turning of the knob 3, making the use of the entire embedded gas valve safer; and it can also make the appearance of the entire embedded gas valve on the reference body more beautiful.

[0050] Specifically, the cover plate 5 is covered on the panel 1 by magnetic attraction, so that the cover plate 5 and the panel 1 can be detachably connected, so that the covering and removing operations of the cover plate 5 are relatively simple and convenient, and will not affect the screwing operation of the knob 3, saving time and effort. In other embodiments, the cover plate 5 can also be covered on the panel 1 by other connection methods, which are not specifically limited here, as long as the cover plate 5 and the panel 1 can be detachably connected.

[0051] Specifically, Figure 1 As shown, the knob 3 includes a knob portion 31 and a mounting portion 32.
