The inner wall of the pipe 100 is also connected with fixing columns 150 respectively positioned at two sides of the valve plate 120; when the valve plate 120 arranged vertically rotates counterclockwise by 90 degrees around the axis of the rotation shaft 110, both ends are blocked by the two fixing posts 150, respectively; the fixing posts 150 are made of magnets, the valve plates 120 are iron plates, and the valve plates 120 are connected by magnetic force in an adsorption manner when rotating to contact the fixing posts 150.
The elastic limiting mechanism 200 comprises a control tank 210 connected to the bottom wall of the pipeline 100, a cylindrical control cavity 220 with the top communicated with the pipeline 100 is arranged in the control tank 210, a movable sliding block 230 is arranged in the control cavity 220, one end, facing the pipeline 100, of the sliding block 230 is connected with a blocking column 240 for blocking the valve plate 120, one end, far away from the pipeline 100, of the sliding block 230 is connected with a spring column 260, the control spring 250 is sleeved on the spring column 260, a baffle 270 is further arranged in the control cavity 220, the spring column 260 slides through the baffle 270, and two ends of the control spring 250 respectively abut against the sliding block 230 and the baffle 270; when the pressure in the pipeline 100 increases, the sliding block 230 is pushed to move along the control cavity 220 in a direction away from the pipeline 100 and drives the blocking column 240 to move, and when the pressure in the pipeline 100 reaches a preset pressure, the blocking column 240 stops blocking the valve plate 120; one end of the control tank 210, which is far from the pipeline 100, is provided with an air vent 280 communicated with the control cavity 220.
The working principle of the butterfly valve device based on pipeline pressure opening and closing provided by the embodiment of the application is as follows: when fluid enters the pipeline 100 on the side of the valve plate 120 facing the blocking block 130, when the fluid enters the pipeline 100 to apply pressure to the surface of the valve plate 120, the blocking block 130 connected with the top of the pipeline 100 presses against one side of the top of the valve plate 120 to block the valve plate 120 from rotating clockwise, at the moment, the pressure of the fluid applied to one side of the sliding block 230 facing the pipeline 100 in the elastic limiting mechanism 200 is equivalent to the thrust of the control spring 250 on one side of the sliding block 230 far away from the pipeline 100, so that the blocking column 240 connected with one side of the sliding block 230 facing the pipeline 100 stretches into the pipeline 100, and thus the blocking column 240 stretching into the pipeline 100 in the elastic limiting mechanism 200 arranged at the bottom of the pipeline 100 presses against one side of the bottom of the valve plate 120 to block the valve plate 120 from rotating anticlockwise, and the same sides at the top and the bottom of the valve plate 120 are blocked by the blocking block 130 and the blocking column 240 respectively, so that the valve plate 120 keeps the pipeline 100 vertically arranged;
when the pressure of the fluid flowing into the pipeline 100 is gradually increased, the pressure of the fluid applied to one side of the sliding block 230, facing the pipeline 100, of the elastic limiting mechanism 200 is larger than the thrust of the control spring 250 to one side, facing away from the pipeline 100, of the sliding block 230, at the moment, the pressure of the fluid applied pushes the sliding block 230 to move along the control cavity 220 in the direction away from the pipeline 100 and drives the blocking columns 240 to move to compress the control spring 250, when the pressure of the fluid flowing into the pipeline 100 reaches a preset value, the pressure applied by the fluid pushes the sliding block 230 to drive the blocking columns 240 to move until the blocking columns are stopped against the bottom side surface of the valve plate 120, so that the pressure applied by the fluid flowing into the pipeline 100 to the top and bottom of the valve plate 120 is unbalanced, the fluid pushes the valve plate 120 and the rotating shaft 110 to overcome the axial anticlockwise rotation of the pulling shaft 110 of the torsion spring 140, so that the normal conveying of the fluid is realized, and when the pressure of the fluid flowing into the pipeline 100 is continuously increased until the axial anticlockwise rotation of the pushing valve plate 120 is kept to be horizontally arranged, the two fixing columns 150 are contacted respectively, and the two ends of the valve plate 120 are mutually adsorbed and connected through magnetic force, and the pipeline 100 is in a normally open state;
when the pressure of the fluid flowing into the pipeline 100 is reduced below the preset pressure, the pressure of the fluid applied to the side, facing the pipeline 100, of the slide block 230 in the elastic limiting mechanism 200 is smaller than the thrust of the control spring 250 to the side, facing away from the pipeline 100, of the slide block 230, at the moment, the control spring 250 pushes the slide block 230 to move along the control cavity 220 towards the direction close to the pipeline 100 and drives the blocking column 240 to move and stretch into the pipeline 100 again, meanwhile, the magnetic force of the fixing column 150 on the valve plate 120 is smaller than the force applied by the torsion spring 140 on the rotating shaft 110, and the torsion spring 140 pushes the rotating shaft 110 to rotate to drive the valve plate 120 to be separated from the fixing column 150 to be adsorbed and rotated to vertically arrange the blocking pipeline 100.
Wherein, the control chamber 220 is further provided with a baffle 270, the spring post 260 slides through the baffle 270, two ends of the control spring 250 respectively press against the slide block 230 and the baffle 270, and the baffle 270 and the spring post 260 are in sliding fit, so that the fluid can push the slide block 230 to stably move along the control chamber 220 to drive the baffle post 240 to move into or out of the pipeline 100 to block or stop blocking the valve plate 120. One end of the control tank 210, which is far away from the pipeline 100, is provided with an air vent 280 communicated with the control cavity 220, and the air vent 280 can balance the pressure difference and prevent the device from being failed due to the sudden increase of the pressure difference.
The embodiments described above are some, but not all embodiments of the application. The detailed description of the embodiments of the application is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
