[0024] Working principle:
[0025] In use, the flat plate valve structure takes the valve body 1 as the main body, is connected with the pipeline through the flanges 2 at both ends, the valve seat ring 3 is arranged in the inside to provide guidance and sealing surface for the movement of the gate plate 41, and the up-and-down moving gate plate 41 controls the flow of medium through the gate hole 42.
[0026] When the flat valve structure is put into use, the gate plate 41 is moved by adjusting the components on the adjusting device 4, so that the gate plate 41 is lifted from the bottom of the valve body 1 until the gate hole 42 corresponds to the valve seat ring 3, so that the medium can flow smoothly through the valve body 1, at this time, the purpose of moving the gate plate 41 is achieved by moving the rotating ring 463 of the rotating device 46, since the limiting disc 462 is rotatably connected with the limiting cylinder 45 through the roller bearing 461, and the inner wall of the limiting disc 462 is threadedly connected with the screw rod 44 through the internal thread hole 464, when the rotating ring 463 drives the limiting disc 462 to rotate, the screw rod 44 is lifted, and when the screw rod 44 is lifted, the connecting disc 48 is driven to slide upward in the limiting cylinder 45, at this time, the connecting disc 48 pulls the push rod 43, the moving push rod 43 drives the gate plate 41 to lift, thereby realizing the opening of the valve, the opening operation of the valve is convenient and simple in a manual manner, the failure rate is lower, so that the valve can be used for a longer time, and the maintenance cost is low, when it is needed to close the valve, the rotating ring 463 is only needed to be reversely rotated, so that the screw rod 44 is lowered, finally the gate plate 41 is pushed down, thereby cutting off the inside of the valve body 1, and the closing of the valve is realized;
[0027] During the opening and closing of the valve, the balance buffer device 47 is arranged to assist, when the gate plate 41 is lifted, the connecting disc 48 will stretch the compression spring 472, when it is lowered, the connecting disc 48 will extrude the compression spring 472, and in the extrusion process, the elastic force generated by the compression of the compression spring 472 will buffer the movement speed of the gate plate 41, when the gate plate 41 is closer to the bottom end of the valve body 1, at this time, the deformation degree of the compression spring 472 is larger, the force required for the rotation of the limiting disc 462 is increased in a pressurized manner, so that the force required for the lowering of the gate plate 41 will be larger, so as to prevent the gate plate 41 from impacting the valve body 1 or the valve seat ring 3 due to too fast speed, thereby playing a role in protecting the valve, at this time, the top end of the gate plate 41 moves downward through the connecting hole 474 on the fixing disc 471, the limiting rod 473 on the fixing disc 471 limits the excessive movement of the connecting disc 48, the compression spring 472 provides uniform thrust to the bottom of the connecting disc 48 through uniform distribution of itself, thereby offsetting the influence of the force deflection in the threaded adjusting process, ensuring the smooth movement of the connecting disc 48, the bottom push rod 43 and the gate plate 41, and further ensuring the accuracy and stability of the valve adjustment.
