Abstract
The utility model provides an air volume adjusting valve. Relates to an air volume adjusting mechanism, in particular to an improvement of an air volume adjusting valve. Provides an air volume adjusting valve with good sealing performance. The valve plate is driven by an electric actuating mechanism to rotate in the valve frame, first sealing mechanisms are arranged between the edge of the long edge of the valve plate and the valve frame and between the adjacent valve plates, and second sealing mechanisms are arranged between the short edge of the valve plate and the valve frame; the gap generated by abrasion is compensated through the release of the elastic potential energy of the elastic piece, so that the sealing performance of the valve plate is still good after the valve plate is used for a long time, and the service life of the valve plate is prolonged.
Description
Technical Field
The utility model relates to an air volume adjusting mechanism, in particular to an improvement of an air volume adjusting valve.
Background
Air regulation valve, also called air damper, be used for building ventilation and the indispensable end fittings in the air purification process among the industrial factory building, civil buildings, generally by pass through the valve frame that the flange is fixed with the pipeline and constitute by electric actuator drive pivoted valve plate in the valve frame, when air damper seals completely, realize sealing through the sealing member between valve plate and the frame, prevent the air leakage, and one side near the pivot tip at the valve plate can only use outstanding metal and valve plate to carry out interference fit and realize sealing, the metal is worn and torn and lead to the clearance too big after opening and close for a long time, here easy air leakage influences air regulation valve's sealed effect after the valve plate seals.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the air volume adjusting valve with good sealing performance.
The utility model is realized by adopting the following technical scheme: the air volume adjusting valve comprises a valve frame and at least one valve plate, wherein a rotating shaft penetrates through the middle of the valve plate, two ends of the rotating shaft are fixed in the valve frame, the valve plate is driven by an electric actuating mechanism to rotate in the valve frame, first sealing mechanisms are arranged between the edge of the long edge of the valve plate and the valve frame and between the adjacent valve plates, and second sealing mechanisms are arranged between the short edge of the valve plate and the valve frame;
the sealing mechanism comprises a sealing sheet fixed on the valve frame, an elastic mechanism is arranged between the sealing sheet and the valve frame, the sealing sheet faces towards the valve plate and one side of the rotating shaft, and the sealing sheet is in contact with the edge of the short edge of the valve plate.
The sealing piece is provided with a limiting groove, when the valve plate rotates to be closed, the limiting groove is clamped at the edge of the valve plate, one side of the limiting groove is a blocking platform, the other side of the limiting groove is a slope, and when the valve plate rotates to be opened, the edge of the valve plate slides out of the limiting groove along the slope.
The first sealing mechanism comprises a buckle and a sealing ball which are fixed on the long edge of the valve plate, the sealing ball is clamped in the buckle, and the edge of the buckle is in contact with the outer wall of the sealing ball.
The sealing ball comprises a ball body and a T-shaped base fixed on the ball body, the T-shaped base is clamped in the buckle and fixes the sealing ball in the buckle, and the edge of the buckle abuts against the outer wall of the ball body.
Compared with the prior art, the sealing sheet can be directly connected with the valve frame through rubber, and the gap generated by abrasion is made up through the release of the elastic potential energy of the elastic piece, so that the sealing performance of the valve plate is still good after long-time use, and the service life of the valve plate is prolonged.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1-4, the air volume adjusting valve includes a valve frame 1 and at least one valve plate 2, a rotating shaft penetrates through the middle of the valve plate 2, two ends of the rotating shaft are fixed in the valve frame 1, the valve plate 2 is driven by an electric actuator to rotate in the valve frame 1, first sealing mechanisms are arranged between the edge of the long side of the valve plate 2 and the valve frame 1 and between the adjacent valve plates 2, and second sealing mechanisms are arranged between the short side of the valve plate 2 and the valve frame 1;
sealing mechanism is including fixing gasket 3 on the valve frame, gasket 3 with be equipped with elastic mechanism between the valve frame, gasket 3 orientation valve plate 2 with pivot vertically one side, gasket 3 with the edge contact of the minor face of valve plate 2. Therefore, when the valve plate 2 rotates, even if the sealing sheet 3 is abraded, the elastic potential energy can be released through the elastic mechanism to enable the sealing sheet 3 to be always attached to the edge of the short edge of the valve plate 2. The sealing plate 3 can be directly connected with the valve frame 1 through rubber, and a gap generated by abrasion is made up through the release of elastic potential energy of the elastic piece 4, so that the sealing performance of the valve plate 2 is still good after long-time use, and the service life of the valve plate is prolonged.
The sealing piece 3 is provided with a limiting groove, when the valve plate 2 rotates to be closed, the limiting groove is clamped at the edge of the valve plate 2, one side of the limiting groove is a blocking platform, the other side of the limiting groove is a slope, and when the valve plate 2 rotates to be opened, the edge of the valve plate 2 slides out of the slope to form the limiting groove. When the valve plate 2 is closed, the valve plate 2 is directly clamped in the limiting groove, a sealing strip can be arranged in the inner wall of the limiting groove, and when the edge is clamped in the limiting groove, the sealing effect can be enhanced through the sealing strip.
The first sealing mechanism comprises a buckle 23 fixed on the long edge of the valve plate 2 and a sealing ball, the sealing ball is clamped in the buckle 23, and the edge of the buckle 23 is in contact with the outer wall of the sealing ball. The sealing ball comprises a ball body 22 and a T-shaped base 21 fixed on the ball body 22, the T-shaped base 21 is clamped in the buckle 23 and fixes the sealing ball in the buckle 23, and the edge of the buckle 23 abuts against the outer wall of the ball body 22. When the adjacent valve plate 2 is closed, the ball 22 moves backwards and the catch 23 pushes forwards against the ball 22, so that the pair of balls 22 abut to provide sealing.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
