Detailed Description

As shown in fig. 1 to 5, a pneumatic opening and closing gate valve comprises a valve frame 1, a gate 2 and a pneumatic device 3; the gate plate 2 is located in the valve frame 1 and is in sliding fit, the pneumatic device 3 is fixedly connected with the gate plate 2 with the valve frame 1, and the pneumatic device 3 telescopically drives the gate plate 2 to be opened and closed with a valve opening 12 on the valve frame 1. Simple structure, through set up flashboard 2 in valve frame 1, pneumatic means 3 is connected fixedly with valve frame 1, and its flexible end is connected with flashboard 2, slides switching valve door 12 through 3 flexible promotion flashboards 2 of pneumatic means along the spout 13 in the valve frame 1, and the switching is swift, once targets in place, low in labor strength, and easy operation is convenient.

In a preferred embodiment, the valve frame 1 is a hollow frame, and a space below the frame inner beam 11 is a valve opening 12. The structure is simple, and during installation, the valve opening 12 on the valve frame 1 is connected with the discharge opening at the bottom of the container and communicated with the container.

In a preferable scheme, a sliding groove 13 is formed in the top of the valve frame 1 through the cross beam 11, and the gate plate 2 is matched with the sliding groove 13. Simple structure, during the installation, flashboard 2 inserts rather than the cooperation from the spout 13 at valve frame 1 top, and flashboard 2 is restricted and slides in spout 13, and is nimble reliable.

In a preferred scheme, two sides of the valve frame 1 are provided with concave insertion grooves 14. Simple structure, during the installation, inserting slot 14 and the cooperation of inserting of the square roof beam of container bottom mount pad both sides, fix again after the cooperation, laborsaving during the installation, operation safety.

In a preferred scheme, the gate plate 2 is a flat plate, and a connecting column 21 is arranged perpendicular to the center of the top and is connected with the pneumatic device 3. Simple structure, during the use, the lower part of flashboard 2 is located valve opening 12, bears the pressure of material in the container, and spliced pole 21 and flashboard 2 are even as an organic whole, and structural strength is high, and occupation space is little.

In a preferred scheme, the bottom of the connecting column 21 is abutted and limited with the cross beam 11 on the valve frame 1. Simple structure, during the use, when the crossbeam 11 on spliced pole 21 bottom and the valve frame 1 is contradicted, the contact of 2 bottoms of flashboard and 13 bottoms of spout, lower limit when restricting flashboard 2 closure simultaneously through spout 13 bottoms and crossbeam 11 avoids pneumatic means 3 to promote too big valve frame 1 of causing of exerting oneself when 2 closed valve mouth 12 of flashboard.

In a preferred scheme, the pneumatic device 3 is a cylinder, and a telescopic end of the pneumatic device is connected with a connecting column 21 of the gate plate 2. The structure is simple, the air cylinder is adopted to push the gate 12 of the opening and closing valve of the gate plate 2, the opening and closing are rapid, the one-time operation is realized, the labor intensity is low, and the operation is simple and convenient.
