Abstract

The utility model discloses an electronic louver valve, which comprises a valve body, the first valve leaf unit of installation on the valve body, second valve leaf unit and third valve leaf unit, establish the actuating mechanism who is connected in the valve body outside and each valve leaf unit, the valve leaf lower extreme of first valve leaf unit and second valve leaf unit is hugged closely along the length direction of valve leaf and is equipped with sealing strip first, the valve leaf upper end of second valve leaf unit and third valve leaf unit is hugged closely along the length direction of valve leaf and is equipped with sealing strip second, sealing strip first and sealing strip second are sunken along length interval in one side in opposite directions and are equipped with assorted magnet first and magnet second. Through the mutual attraction of the magnets A and the magnets B in the sealing strips A and the sealing strips B, the sealing strips A and the sealing strips B are closed, so that gaps among the valve leaves of the first valve leaf unit, the second valve leaf unit and the third valve leaf unit are closed, and the sealing performance of the louver valve among the closed valve leaves is improved.

Description

Electric louver valve

Technical Field

The utility model belongs to the valve field, concretely relates to electronic louver valve.

Background

The electric louver valve is matched with an electric actuating mechanism for use, has the advantages of small opening and closing moment, sensitive action, reliable performance, large caliber, light weight and the like, is widely applied to cement, metallurgy, mines and the like, and well solves the problems that opening and closing are needed and the air quantity needs to be effectively controlled when each pipeline is ventilated.

The sealing performance between the valve vanes of the prior art louver valves after closing is still to be improved, so that the improvement is still needed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art exists, the utility model provides an electronic louver valve has improved the leakproofness of louver valve between closed back valve leaf.

The utility model discloses a realize through following technical scheme: the utility model provides an electronic louver valve, includes the valve body, first valve leaf unit, second valve leaf unit and the third valve leaf unit of installation on the valve body establish the actuating mechanism in the valve body outside and each valve leaf unit connection, the valve leaf lower extreme of first valve leaf unit and second valve leaf unit is followed the length direction of valve leaf is hugged closely and is equipped with sealing strip first, the valve leaf upper end of second valve leaf unit and third valve leaf unit is followed the length direction of valve leaf is hugged closely and is equipped with sealing strip second, sealing strip first and sealing strip second are sunken to be equipped with assorted magnet first and magnet second along length interval on one side in opposite directions.

Further, the magnet A and the magnet B are level to the surfaces of the sealing strip A and the sealing strip B.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an inter attraction of magnet first and magnet second in sealing strip first and the sealing strip second for sealing strip first and sealing strip second are closed, and then make the clearance between the valve leaf of first valve leaf unit, second valve leaf unit and third valve leaf unit sealed, have improved the leakproofness of tripe valve between closed back valve leaf.

Detailed Description

The electric louver valve comprises a valve body 1, a first valve leaf unit 2, a second valve leaf unit 3 and a third valve leaf unit 4 which are installed on the valve body 1, and a driving mechanism 5 which is arranged on the outer side of the valve body 1 and connected with the valve leaf units 6, wherein sealing strips A7 are tightly attached to the lower ends of the valve leaves 6 of the first valve leaf unit 2 and the second valve leaf unit 3 along the length direction of the valve leaves 6, sealing strips B8 are tightly attached to the upper ends of the valve leaves 6 of the second valve leaf unit 3 and the third valve leaf unit 4 along the length direction of the valve leaves 6, and matched magnets A9 and B10 are recessed on the surface of one side, opposite to the sealing strips A7 and the sealing strips B8, along the length interval.

When the valve leaves are closed, the magnets A9 and B10 in the sealing strips A7 and B8 attract each other, so that the sealing strips A7 and B8 are closed, and gaps among the valve leaves 6 of the first valve leaf unit 2, the second valve leaf unit 3 and the third valve leaf unit 4 are closed.

The magnet A9 and the magnet B10 are level with the surfaces of the sealing strip A7 and the sealing strip B8, and no gap is formed between the sealing strip A7 and the sealing strip B8.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
