The utility model discloses a kind of pneumatic pellet valve, the cover board including setting in valve body, valve body, the bottom cover positioned at valve body tail end and for storing cover board and the driving mechanisms for driving cover board to work；Valve body includes the valve plate one with feed inlet and the valve plate two with discharge port, and valve plate two is provided with overflow port in its discharge outlet, which is obliquely installed from two inner wall of valve plate to discharge outlet；When pneumatic pellet valve is in close state, the intracorporal particle of valve pushes to overflow port by cover board and flows out, which solves the problems, such as that bottom cover blocking causes that pellet valve can not be closed by the way that overflow port is arranged；The agility of the pneumatic safety and operation for replacing improving personnel manually；Extend the service life of pneumatic pellet valve.
Description
Technical field
The utility model relates to valves, are related to a kind of pneumatic pellet valve.
Background technique
Traditional pellet valve, is also baiting valve, is to drive screw rod to rotate on bracket using handwheel, to drive screw rod lower end
Valve rod move up and down, so that the valve plug with ovable valve stem lower end moves up and down so that the discharge port cooperation on valve plug and lower hopper,
Realize the on-off of pellet valve.
Since particle is smaller and flow velocity is relatively slow, while the cover board of pneumatic pellet valve has certain thickness, because
For this pneumatic pellet valve when closing, cover board push particle enters bottom cover for storing in the cavity on cover board top, with
Grain increases, and cavity is particles filled, and cover board cannot be introduced into cavity, causes pellet valve that can not be closed, and particle continues to convey,
Lead to the waste of raw material.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide a kind of pneumatic pellet valve, which solves particle
The problem of cavity body of blocking bottom cover causes cover board that can not be closed.
Technical solution: pneumatic pellet valve described in the utility model, including set in valve body, valve body cover board, be located at valve body
Tail end and the bottom cover for storing cover board and the driving mechanism for driving cover board to work；Valve body includes the valve with feed inlet
Plate one and valve plate two with discharge port, valve plate two are provided with overflow port in its discharge outlet, and the overflow port is from two inner wall of valve plate
Place is obliquely installed to discharge outlet；When pneumatic pellet valve is in close state, the intracorporal particle of valve pushes to overflow by cover board
Mouth outflow.
By using above-mentioned technical proposal, particle is discharged by elevator or particle from eminence, is entered by feeder pipe
Into injection molding machine or other heating equipments, therefore the pneumatic pellet valve is mounted on vertical feeder pipe.Pneumatic pellet valve
Above, discharge port is in lower section for feed inlet；Wherein the overflow port of discharge outlet is tilted from pellet valve inner wall towards discharge port, and is
Top-down inclination.When driving mechanism driving cover board closes the pneumatic pellet, particle can be fallen on cover board, particle is in cover board
Drive under enter in valve body, discharge outlet is in subnormal ambient, while the overflow port is also at subnormal ambient, and particle is from cover board
It is drawn onto overflow port, enters discharge port from overflow port, while cover board closes pellet valve.
The utility model has the advantages that the pneumatic pellet valve solves bottom cover blocking by setting overflow port cause that pellet valve can not be closed
Problem；The agility of the pneumatic safety and operation for replacing improving personnel manually；Extend the service life of pneumatic pellet valve.
Detailed description of the invention
Fig. 1 is pneumatic pellet valve overall structure diagram；
Fig. 2 is the structural schematic diagram that valve body and cover board combine；
Fig. 3 is the B-B cross-sectional view of Fig. 2.
Specific embodiment
As shown in Figure 1, a kind of pneumatic pellet valve, including set in valve body 1, valve body 1 cover board 2, be located at 1 tail end of valve body and use
In storage cover board 2 bottom cover 3 and for drive cover board 2 work driving mechanism 4, driving mechanism 4 include cylinder 41 (in figure not
Show), connecting rod 42 and bracket 43, bracket 43 connects with cylinder 41 and valve body 1 respectively, and connecting rod 42 connects cylinder 41 and works
End and cover board 2.The cylinder body of cylinder 41 is provided with the cabinet 11 for covering cylinder 41, and cabinet 11 avoids cylinder 41 and control gas
The other components exposures of cylinder 41 outdoors, can thus extend the service life of pellet valve.
As shown in Figures 2 and 3, valve body 1 includes the valve plate 1 with feed inlet 5 and the valve plate two with discharge port 6
102, valve plate 2 102 is provided with overflow port 7 at its discharge port 6, and the overflow port 7 is from 2 102 inner wall of valve plate at discharge port 6
It is obliquely installed；When pneumatic pellet valve is in close state, the particle in valve body 1 pushes to overflow port 7 by cover board 2 and flows out.
Grain passes through elevator, and perhaps particle enters in injection molding machine or other heating equipments from eminence release by feeder pipe, therefore
The pneumatic pellet valve is mounted on vertical feeder pipe.Above, discharge port 6 is in lower section for the feed inlet 5 of pneumatic pellet valve；Wherein
Overflow port 7 at discharge port 6 is tilted from pellet valve inner wall towards discharge port 6, and is top-down inclination.When driving mechanism 4
When cover board 2 being driven to close the pneumatic pellet, particle can be fallen on cover board 2, particle enters in valve body 1 under the drive of cover board 2, out
Material mouth 6 is in subnormal ambient, while the overflow port 7 is also at subnormal ambient, and particle is drawn onto overflow port 7 from cover board 2, from overflow
Head piece 7 enters discharge port 6, while cover board 2 closes pellet valve.
Overflow port 7 has little time to handle particle in order to prevent, is provided on the inner wall of the valve plate 2 102 above overflow port 7
For increasing the stock chest 8 of storage particle, stock chest 8 first stores particle, and particle Shunzi overflow port 7 is flowed into discharge port 6.For
The discharge rate for increasing overflow port 7, in valve plate 2 102 is provided with the annular slab for increasing by 7 length of overflow port at discharge port 6
9, increase the length and opening of overflow port 7 by increasing annular slab 9.
Bottom cover 3 is provided with cavity in bottom cover 3 for storing its front end portion of cover board 2 when closing pellet valve, covers
Plate 2 is understood in the cavity that bring micro particle into bottom cover 3, and valve plate 1 and valve plate 2 102 are fixed by pin and form valve body
1, bottom cover 3 and valve body 1 are to be detachably connected, convenient for opening the particle that bottom cover 3 is cleared up in cavity when later period maintenance.
As shown in Figure 1, the tail end of bottom cover 3 is provided with for equipped with plug in order to which the later period does not open bottom cover 3 in maintenance process
The air inlet 10 of son；When maintenance, plug is taken out, air pump is connected with bottom cover 3, the particle in bottom cover 3 is blown into overflow port 7
It is interior, keep bottom cover 3 clean and tidy.
