The transmission support ring 29 is between the limit step 2801 and the limit hole 37, and is connected to the transmission support rod 28 using an open pin 10 to pass through the limit hole 37.

[0030] In order to further improve the sealing performance, a sealing gasket 8 is provided on the outer periphery of the sealing support plate 19, and a connecting groove is opened on the upward side of the sealing gasket 8.

The lower end of the spring 2 31 can abut against the upper side of the limit step 2801, and the upper end of the spring 2 31 can abut against the upper side of the ball head pressure block 18.

[0032] In order to further realize the linear lifting and lowering of the valve stem, a roller is rotatably connected to the lower shell, and the valve stem abuts against the outer periphery of the roller. The valve stem 6 is between the roller and the driving gear 16, and the upper part of the valve stem 6 is connected to the valve body 3 via a linear bearing 15.

[0033] In the present invention, the valve body 3 is connected to the reactor through the opening 10; when the valve body 3 needs to be sealed, the driving gear 16 is controlled to rotate, and the rotation of the driving gear 16 drives the movement of the transmission rack, and the rotation direction of the driving gear 16 is controlled to make the transmission rack move up and the valve stem 6 rise. The working principle for realizing the rotation of the driving gear 16 is that when the electric drive main shaft 9 needs to rotate, the motor 5 is actuated, the main shaft 9 rotates, the main shaft 9 drives the worm 36 to rotate, the worm 36 drives the worm wheel 26 to rotate, the transmission pin 27 abuts on the claw 3001, the worm wheel 26 drives the rotation of the transmission block 30, the transmission block 30 drives the rotation of the main shaft 9, the rotation of the main shaft 9 drives the rotation of the active bevel gear 25, and the rotation of the active bevel gear 25 drives the rotation of the test bevel gear 24 , the rotation of the test bevel gear 24 drives the rotation of the sensor shaft 23, and the encoder 22 records the number of revolutions of the sensor shaft 23, so as to facilitate the calculation of the rotation angle of the main shaft 9. When the rotation angle of the main shaft 9 reaches the set angle, that is, when the sealing gasket 8 seals the opening 10, the motor 5 stops moving; when there is no need to electrically drive the main shaft 9 to rotate, the adjusting handle 21 is rotated counterclockwise to make the lifting block 32 abut against the transmission support ring 29, and the lifting block 32 pushes the transmission support ring 29 to move in the direction of the transmission block 30, and the transmission support ring 29 pushes the transmission block 30 to move in the direction away from the worm gear 26, and the adjusting handle 21 is continued to be rotated to make the lifting block 32 continue to move in the direction of the transmission support ring 29. When the lifting plate 35 abuts against the worm gear 26 When the valve body 3 at the opening 10 is in the upper position, the adjusting handle 21 is stopped from rotating and the adjusting handle 21 is kept in this position. At this time, the claw 3001 completely leaves the transmission pin 27, and the hand wheel 17 is manually rotated. The hand wheel 17 drives the rotation of the main shaft 9, and the worm gear 26 does not rotate. When the rotation angle of the main shaft 9 reaches the set angle, that is, when the sealing gasket 8 seals the opening 10, the hand wheel 17 is stopped from rotating and the adjusting handle 21 is loosened. The adjusting handle 21 returns to its original position under the action of the torsion spring 33, and the torsion spring 33 is reset, and the limit plate abuts against the limit bolt 20; when the sealing gasket 8 contacts the valve body 3 at the opening 10, the sealing gasket 8 is automatically aligned under the action of the global head 1401 to seal the opening 10; when unloading is required, the valve body 3 is connected to the reactor, and the motor 5 is controlled to reverse or reverse. The hand wheel 17 is turned in the direction, the driving gear 16 rotates in the opposite direction, the transmission rack moves downward, the valve stem 6 descends, and when the valve stem 6 descends to the position of the blocking step 12, the sealing support plate 19 is tilted, and the dust falls from the opening 10. The structure of the present invention is simple, and the weight of the transmission block 30 is reduced by setting the transmission support ring 29. The transmission support ring 29 can be lifted upward without much force, so that the manual and electric independent driving of the valve stem 6 can be realized, and the work is more reliable. When the valve stem 6 descends to a certain position, the sealing pad 8 is blocked, and the valve stem 6 continues to descend, and the sealing support plate 19 rotates around the ball head and tilts. In this way, when the upper end falls, the powder falls on the inclined sealing plate and automatically slides down, and there will be no large amount of powder accumulation, and no dust will be raised when blowing.When the valve stem 6 rises from the lowest position, the sealing plate will automatically turn flat gradually due to the action of the lower end spring 2 31, so that when it reaches the uppermost end, the automatic alignment and sealing will not be affected by the excessive inclination angle; it can be used in the work of high-risk powder aggregates. ;

[0034] The present invention is not limited to the above-mentioned embodiments.
