Compression degree between body 8, using more convenient；In the present embodiment, discharge hole 7 is can be with exterior material conveying pipe phase screw thread
The threaded hole of connection, so can more easily be connected with exterior material conveying pipe；In the present embodiment, dynamic close
Coordinate both spacing relative rotation positions between envelope body 11 and static seal body 8 by way of positive stop key and limiting slot；In this reality
Apply in example, some circle sealing ring placing grooves 25 are provided with the valve rod 1 in the valve body 4 below inner cavity 5 from up to down, every
The sealing ring 26 in gap between energy sealed valve stem 1 and valve body 4 is placed with a sealing ring placing groove 25, can so improve valve rod
Leakproofness between valve body；In actual installation, valve body 4 can pass through the flange 24 that sets on its external wall and reaction kettle 2
3 phase of blowing pipe nipple fix；In actual production, the component such as valve rod, valve body, static seal body and dynamic sealing body can use resistance to height
Super high molecular material polyphenylene sulfide or polyether-ether-ketone of warm, wear-resisting, resistance to nearly all organic solvent corrosion etc. are made；
The operation principle of the present invention is as follows：
During installation, first static seal body 8 is matched somebody with somebody by the internal thread 22 of groove 21 and the 23 phase screw thread of external screw thread of 4 upper end of valve body
Close and be locked on valve body 4, valve rod 1 is then sequentially passed through into valve body 1 and static seal body 8 from bottom to top, then will be dynamic close
Envelope body 11 is sleeved on the square column of 1 upper end of valve rod, is then screwed on the first locking nut 10 again, is then sleeved on spring 15 from bottom to top
On valve rod 1, then spring tray 14 is screwed on valve rod 1 by thread fitting, then rotation spring pallet 14, makes spring tray 14
Upward holddown spring 15, at this time spring 15 moved down by spring tray 14 with ovable valve stem 1 to make the first locking nut on valve rod 1
Dynamic sealing body 11 is pressed downward tightening seal fitting static seal body 8 by 10, and rotation handle 13 is then sleeved on to the square column of the lower end of valve rod 1
On, the second locking nut 18 is then screwed on again, so as to complete the overall assembling of bottom valve, is then inserted upwardly into the bottom valve assembled
In the blowing pipe nipple 3 of reaction kettle 2, bolts and nuts are reused by the method on the flange 24 on the valve body 4 of bottom valve and blowing pipe nipple 3
It is blue mutually fixed, so that bottom valve and 3 phase of blowing pipe nipple be fixed, due to bottom valve valve body 4 discharge hole 7 upper edge to dynamic sealing body 11
Upper surface between length just match the length of blowing pipe nipple 3, so when valve body 1 is fixed with 3 phase of blowing pipe nipple, move close
The upper plane of envelope body 11 just mutually suits with bottom surface reaction kettle 2 inside, so as to by the inside of blowing pipe nipple 3 and reaction kettle 2
Isolation is fully sealed, effectively eliminates adverse effect of the blowing pipe nipple to chemical reaction accuracy in reaction kettle, ensure that reaction
The accuracy of chemical reaction in kettle, while the solid reaction for being also prevented from unreacted solid material in reaction kettle and being generated after reacting
Thing is deposited in blowing pipe nipple, avoids exterior material conveying pipe from being blocked when being blocked in blowing；
In use, when needing to close bottom valve, rotation handle 13 need to be only rotated, makes 1 synchronous drive dynamic sealing body 11 of valve rod
First charging hole 9 of the second charging hole 12 and static seal body 8 that turn to dynamic sealing body 11 is staggered, at this time feeding-passage then by
Cut-out；When needing to open bottom valve, reversion rotation handle 13 is only needed, turns to 1 synchronous drive dynamic sealing body 11 of valve rod dynamic close
Second charging hole 12 of envelope body 11 is connected with the first charging hole 9 of static seal body 8, and the material in reaction kettle 2 will be from this time
The feeding-passage that second charging hole 12 and the first charging hole 9 are formed enters in the inner cavity 5 of valve body 4, and the material into inner cavity 5 passes through again
Discharge hole 7 is discharged into exterior material conveying pipe.It is an advantage of the invention that：Service life is grown, good airproof performance, installation and maintenance and operation
It is extremely convenient, and can make the inside of blowing pipe nipple and reaction kettle that isolation be fully sealed, blowing pipe nipple is completely eliminated to reaction
The adverse effect of accuracy is chemically reacted in kettle, ensure that the accuracy of chemical reaction in reaction kettle, while is also prevented from reaction kettle
The solid reactant generated after interior unreacted solid material and reaction is deposited in blowing pipe nipple, also avoids exterior material from conveying
Line clogging is blocked in blowing.
