Detailed Description
A high-temperature-resistant airtight valve comprises an actuating mechanism 1, a valve body 2, a blade shaft 3 and a blade 4, wherein the actuating mechanism 1, the blade 4 and the blade shaft 3 are arranged on the valve body 2, the blade 4 is matched with the blade shaft 3, and the actuating mechanism 1 is connected with the blade shaft 3; the method is characterized in that: the blade 4 comprises a blade body 6 and a sealing device 5, and the blades 4 are matched through the sealing device 5; the blade body 6 comprises an upper blade 8 and a lower blade 9, a sealing device 5 is arranged between the upper blade 8 and the lower blade 9, the sealing device 5 comprises a circular sealing structure 10 and an arc sealing structure 11, the circular sealing structure 10 is arranged on the upper side and the lower side of the upper blade 4 and on the lower side of the lower blade 4, and the arc sealing structure 11 is arranged on the upper side of the lower blade 4; the circular sealing structure 10 is matched with the circular arc sealing structure 11.
The round sealing structure 10 is provided with an outer bag body 12, the outer bag body 12 is made of an elastic galvanized steel plate, and the main body of the round sealing structure 10, the circular arc sealing structure 11, the upper blade 8 and the lower blade 9 are made of stainless steel plates. The valve body 2 is provided with baffle plates 13 in up-down symmetry, and the baffle plates 13 are matched with the circular sealing structure 10. The size of the outer enclosure 11 is slightly larger than the body of the circular sealing structure 10.
In the specific implementation: when a fire disaster happens, the normally open blades are matched through a connecting rod device under the driving of an actuating mechanism of the valve body to be sealed; the sealing device clamped between the upper blade and the lower blade adopts a metal material to replace the existing rubber material, so that the high-temperature resistance is better, the safety is improved, and smoke exposure is prevented. The closed structure consists of a circular sealing structure and an arc sealing structure which are made of stainless steel; an outer wrapping body is arranged outside the circular sealing structure and is made of an elastic galvanized steel sheet, and the outer wrapping body is pressed on the circular sealing structure and then is fixed between the upper blade and the lower blade; the two blades are sealed by matching a circular sealing structure and an arc sealing structure; then when the blades are closed, the outer bag body on the blades is in contact extrusion with the circular arc-shaped structure, and the outer bag body can be effectively deformed and sealed after being pressed because a gap is reserved between the outer bag body and the circular sealing structure; after the door is opened, the door can be effectively reset due to elasticity; the high-temperature resistant performance of the airtight valve is effectively improved under the condition that the existing functions are not influenced.
