[0019] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.
[0020] The present utility model provides a high-temperature resistant air valve blade structure as shown in Figures 1-4 which includes a blade body 1. The blade body 1 is composed of an upper blade 2, a lower blade 3 and a stainless steel sealing sheet 4. Both the upper blade 2 and the lower blade 3 are made of galvanized sheets. Both ends of the upper blade 2 adopt a flat structure. One end of the lower blade 3 adopts a hooked arc structure, and the other end of the lower blade 3 adopts a flat structure. The upper blade 2 and the lower blade 3 are fixedly connected. The upper blade 2 and the lower blade 3 are fixedly connected by riveting. One end of the stainless steel sealing sheet 4 is inserted into the connection between the upper blade 2 and the lower blade 3, and the stainless steel sealing sheet 4 is arranged at the hooked arc structure of the lower blade 3. The stainless steel sealing sheet 4 is made of stainless steel metal material and can meet the high-temperature resistant requirements.
[0021] As shown in Figures 1-2 , adjacent two blade bodies 1 are hermetically connected through the stainless steel sealing sheet 4. When the air valve is closed, the flat surface of the left blade body 1 presses on the stainless steel sealing sheet 4 of the right blade body 1, achieving a sealing effect.
[0022] As shown in Figures 2-4As shown, the surfaces of the upper blade 2 and the lower blade 3 are both provided with the same bending grooves, and the upper blade 2 and the lower blade 3 can form a hexagonal pattern and a quadrilateral pattern when they are fitted together.
[0023] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
