Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a valve seat structure of an air valve. Background Art

[0002] During daily cooking, the fumes generated in the kitchen need to be discharged outdoors in a timely manner. Modern buildings are generally built with public flues. The range hood absorbs the fumes in the kitchen and discharges them to the public flue. Since the density of high-temperature fumes is less than the density of air, the fumes will rise in the public flue. For this reason, when residents on higher floors use range hoods to exhaust fumes to the public flue, they often encounter difficulties in exhausting fumes or even the problem of fumes in the public flue flowing back and causing indoor odor.

[0003] In order to solve the problems of oil smoke backflow and odor in the public flue of high-rise residential buildings, many electric check valves, also collectively referred to as electric air valves, have appeared on the market, and their air inlets and outlets are usually circular tube structures. When it is necessary to install it on the air duct connecting the range hood and the public flue, the circular tube air valve can be installed on the air duct by plugging, etc.; but when the air valve needs to be directly installed on the wall of the public flue or other flat walls, the circular tube air valve will be difficult to install or even impossible to install, so it needs to be improved.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] As attached Figure 1-4As shown, a damper seat structure includes a seat body 1 and a seal 3. The damper seat structure is used to serve as an intermediate transition structure between the damper body 2 and the flue wall or other plane wall, so as to install and fix the damper body 2 on the flue wall or other plane wall.

[0031] The valve seat body 1 comprises an integrally arranged valve seat base 11 and a connecting portion 12 , wherein the valve seat base 11 is used for being fixedly connected to the flue wall, and the connecting portion 12 is used for being connected and fixed to the air valve body 2 .

[0032] The valve seat base 11 is a flat plate structure, and its shape can be square, rectangular or other polygonal, etc. The shape and size of the connecting portion 12 and the air valve body 2 are adapted to ensure that the connecting portion 12 and the air valve body 2 can be connected and fixed.

[0033] The existing air valve body 2 is a circular tube structure, so the connecting portion 12 is a cylindrical structure, and the axis of the connecting portion 12 passes through the center position of the valve seat base 11 .

[0034] As attached Figure 3-5 As shown, the connecting portion 12 is plugged and matched with the damper body 2. In this embodiment, the inner diameter of the connecting portion 12 is the same as the outer diameter of the damper body 2, thereby ensuring the sealing between the damper body 2 after the damper body 2 is inserted into the connecting portion 12. In some other embodiments, the inner diameter of the connecting portion 12 may be slightly smaller than the outer diameter of the damper body 2, thereby utilizing the interference fit between the connecting portion 12 and the damper body 2 to improve the airtightness of the plug-in fixing point of the damper body 2 and the connecting portion 12.

[0035] The connecting portion 12 is provided with a plurality of fixing holes 121 , and the first connecting member passes through the fixing holes 121 and is inserted into the air valve body 2 to prevent the air valve body 2 and the connecting portion 12 from being loosened.

[0036] In this embodiment, two fixing holes 121 are provided on the connecting portion 12, and the two fixing holes 121 are symmetrically distributed. The first connecting member is preferably a screw.

[0037] The valve seat base 11 is provided with a plurality of mounting holes 112 , and the second connecting member passes through the mounting holes 112 and is inserted into the flue wall or other flat wall to fix the valve seat base 11 on the flue wall or other flat wall.

[0038] In this embodiment, four fixing holes 121 are provided on the valve seat base 11, and the four fixing holes 121 are respectively distributed at four corners of the valve seat base 11. The second connecting member is preferably a screw.

[0039] A valve seat flange 111 is provided at an edge of the valve seat base 11 on a side away from the connecting portion 12. The valve seat flange 111 is an annular protrusion, which can enhance the overall structural strength of the valve seat base 11.

[0040] The height h of the valve seat flange 111 is in the range of 3-5 mm, preferably 4 mm, so that a certain extrusion and diffusion space can be reserved for the sealant between the valve seat base 11 and the flue wall during the bonding and sealing process of the valve seat body 1 and the flue wall, thereby preventing the sealant from being completely squeezed out of the gap between the valve seat base 11 and the flue wall.

[0041] After the damper body 2 and the connection part 12 are connected and fixed, a sealing member 3 can be arranged outside the connection position of the damper body 2 and the connection part 12 to enhance the sealing effect between the damper body 2 and the connection part 12. In this embodiment, the sealing member 3 is a sealing tape, which is wound and fixed at the plug-in fixing position of the damper body 2 and the connection part 12, and can ensure the sealing between the damper body 2 and the connection part 12 to prevent the escape of oil smoke.

[0042] In particular, in order to ensure the connection strength between the air valve body 2 and the connection portion 12 and to facilitate the use of the seal 3, the axial length H of the connection portion 12 is not less than 25 mm.

[0043] The implementation principle of the above embodiment is:

[0044] When installing the air valve body 2, firstly, screw through the four mounting holes 112 on the valve seat base 11 and screw into the flue wall or other flat wall to fix the valve seat body 1 on the flue wall or other flat wall. At this time, the air valve body 2 can be aligned and inserted into the connecting portion 12 on the valve seat body 1, and then screw through the fixing holes 121 on the connecting portion 12 and screw into the air valve body 2 to achieve mechanical anti-detachment fixation of the air valve body 2. Finally, the air valve body 2 can be installed and fixed on the flue wall by completely sealing the gap between the air valve body 2 and the connecting portion 12 with the seal 3. The setting of the valve seat body 1 effectively improves the adaptability of the air valve body 2 to different installation environments.
