Background technique
Bottom open type baiting valve applies in general to reaction kettle, and the charging and discharging for reaction kettle use, and traditional bottom open type is put
Linear sealing is sealed between spool and valve circle in material valve, wherein the sealing surface that spool is contacted with valve circle is circular conical surface, works as material
When for liquid and solid mixed solution, fraction solids particle accumulation is between spool and valve circle, and when rotating valve handle, valve rod is pushed
Spool moves upwards, and since solid particle is stuck between spool and valve circle, causes spool and the sealing surface of valve circle that cannot connect completely
Touching generates gap, leads to poorly sealed, generation leakage.Since card has solid particle in spool and valve circle, lead to spool and valve circle
Sealing surface be forced out pit, even if after cleaning up solid particle, spool valve circle close in place after, can also generate leakage.
Simultaneously because, since spool and valve circle are rubber product, frictional force is larger, passes through rotation in spool decline
Mode declines the abrasion that can accelerate spool and valve circle.

Specific embodiment
A kind of bottom open type baiting valve, including valve body 12 and power module, further includes: feed zone 1 and with the feed zone 1
The discharging section 2 of lower end inclination connection is provided at the lower wall of the discharging section 2 and be connected to inside the valve body 12 and downward
The through-hole of extension；Upper holder block 13 is fixedly connected to be ladder-like with valve body 12；Screw 11, passes through valve body 12 and upper holder block 13 is fixed
Connection；Valve circle 14 is set at the feeding inlet of the feed zone 1, is fixedly connected with upper holder block 13 and valve body 12；Motor 3, installation
Outside valve body 12, it is electrically connected with power module；Spool 15, be located at the feed zone 1 in, the outer peripheral surface of the spool 15 with it is described
The cooperation sealing of valve circle 14；Valve rod is fixedly connected across the through-hole with motor 3, is rotatablely connected with spool 15.
The spool 15 be hemispherical, and and bottom be provided with blind hole 10；The blind hole 10 is equipped with metal threaded；Institute
The blind hole 10 and valve rod stated are rotatablely connected；The spool 15 further includes limit card slot 9,15 bottom of spool is installed on, with spool
15 are fixedly connected；The limit card board center is provided with hole, passes through for valve rod.
The valve rod includes: upper boom 6, is cylindrical, massive bar, is rotatablely connected with spool 15, and top is equipped with screw thread, with
Screw thread in blind hole 10 matches, and is equipped with screw thread in its bottom；Limit film 7, below the screw thread on the top of upper boom 6；Outer bar
5, it is hollow stem, is inserted in hole, is fixedly connected with valve body 12；Lower beam 4, height is identical as outer bar 5, is cylinder type hollow
Bar is mounted in outer bar 5, is rotatablely connected with outer bar 5, is rotatablely connected with upper boom 6, and inside is equipped with screw thread at an upper portion thereof, with upper boom 6
The screw thread of bottom match, bottom is solid；Drive rod, one end are fixedly connected with lower beam 4, the other end pass through valve body 12 with
Motor 3 is fixedly connected.
The inside of the valve circle 14 is the hemispherical for removing top cover；The outside of the valve circle 14 is equipped with to center and tilts
Chamfering.
Hole of the limit card board around center is provided with diameter groove 8 identical with limit film 7；The groove 8
It is interior to be equipped with screw thread.The top of the outer bar 5 is located above 1 lower end of feed zone.
The regulation to charging rate may be implemented by the mutual cooperation of screw thread in the utility model；By the structure of screw thread,
Spool 15 can be made to be driven by motor 3 to rotate, particulate matter is thrown away into 15 surface of spool under the influence of centrifugal force, and realized
The remaining effect of automatic cleaning, also improves leakproofness；Limit card slot 9 and limit film 7 and screw thread are used cooperatively, so that rubbing
When wiping power is larger, upper boom 6 is first exited from blind hole 10, and then limit film 7 is contacted with the bottom of limit card slot 9, so that spool 15
The pressure being subject to reduces, while subject to downward force, so that spool 15 is more easier to separate with valve circle 14, to reduce
Abrasion, improves the service life of spool 15 and valve circle 14；The chamfer design of valve circle 14 can be scattered in valve circle 14
Material enters in valve under gravity；The height of outer bar 5 makes, and does not have material and leaks along the gap of outer bar 5,
Substantially increase leakproofness.
In use, when open, motor 3 drives lower beam 4 to rotate so that 6 stress of upper boom moves down, and spool 15 with
Frictional force is larger between valve circle 14, so only upper boom 6 drives limit film 7 to rotate down, when limit film 7 touches limit card slot
When 9 bottom, power and a biggish downward pulling force of the spool 15 by a lesser rotation, so that spool 15 and valve circle
At this moment 14 separation can control the size of opening by the circle number of the control rotation of motor 3, when closed, motor 3 drives lower beam
4 and upper boom 6, final band movable valve plug 15 rotates upwards, when rotation, makes to be attached to spool 15 under the influence of centrifugal force
The material on surface has been thrown in feed zone 1, has achieved the effect that clear up spool 15, when spool 15 touches valve circle 14, valve
Core 15 finally is influenced to stop operating by frictional force, but upper boom 6 continues to rotate, and finally holds out against spool 15 and valve circle 14, mentions
Leakproofness is risen；Herein, the lead angle very little of the screw thread of the screw thread and lower beam 4 of 6 bottom of upper boom, so self-locking function obtains
Great promotion has been arrived, has been not susceptible to screw thread landing, and due to the relationship of the frictional force between spool 15 and valve circle 14, it will not
Spool 15 is caused to be opened because of the landing of screw thread；Outer bar 5 is attached with valve body 12 using the form of welding in design, and because
It is located at the top of 1 bottom end of feed zone for the top of outer bar 5, so not having material enters outer bar 5, it is therefore prevented that material leakage
Occur, also improves leakproofness.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
