Detailed Description
Example 1
As shown in fig. 1-4, the utility model provides a valve tap bearing sealing device, which comprises a valve seat 1, a valve channel 4, a sealing gasket 5, a pressing block 6, a ratchet wheel 8 and a connecting rod 10;
The valve seat 1 is internally provided with a valve shaft lever 2 in a rotating way, and the inner end of the valve shaft lever 2 is provided with a bearing 3; two valve channels 4 are arranged in the valve seat 1, and sealing gaskets 5 are arranged in the two valve channels 4; the two pressing blocks 6 are respectively arranged in the two valve channels 4, screw rods 7 are respectively and rotatably arranged at the bottoms of the two pressing blocks 6, the two screw rods 7 are in threaded connection in the valve seat 1, and the bottom ends of the two screw rods 7 respectively extend out of the valve seat 1; the two ratchets 8 are respectively arranged at the bottom ends of the two screw rods 7, pawls 9 are respectively arranged at the outer sides of the two ratchets 8, and the two pawls 9 are respectively and rotatably connected to the bottom surface of the valve seat 1; two connecting rods 10 are provided at the bottom ends of the two screws 7.
Working principle: when the sealing gasket 5 is used, when the sealing property is weakened, the screw rod 7 can be rotated, the screw rod 7 can be spirally lifted in the valve seat 1 to drive the pressing block 6 to move upwards, the valve channel 4 and the pressing block 6 are in a truncated cone shape with opposite directions, so that the pressing block 6 moves upwards to plug the valve channel 4, if the sealing property of the valve channel 4 is weakened, the screw rod 7 can be rotated again to drive the pressing block 6 to move upwards to enhance the sealing property, the screw rod 7 is rotated in the process of rotating the screw rod 7, the ratchet wheel 8 rotates along with the screw rod, when the rotation is finished, the pawl 9 can rebound due to the rebound of the torsion spring 12 to stop the rotation of the ratchet wheel 8, the rotation of the screw rod 7 is stopped along with the pawl 9, the screw rod 7 can be fixed to prevent the falling back, and meanwhile, the connecting rod 14 can be inserted into the connecting block 13, and the screw rod 7 can be rotated by rotating the rotating rod 15 to facilitate force application.
In this embodiment, through setting up to pressing block 6, screw rod 7, valve passageway 4, when sealing washer 5's leakproofness weakens, can be through rotating screw rod 7, screw rod 7 spiral rises in valve seat 1, drives to press block 6 upward movement, because valve passageway 4 is the round platform shape opposite in direction with pressing block 6, so press block 6 upward movement just can plug valve passageway 4, if valve passageway 4's leakproofness also weakens, can rotate screw rod 7 once more, drives to press block 6 upward movement just can strengthen the leakproofness.
