Description
Technical field
The utility model relates to the constructional device on a kind of vacuum filter, specifically a kind of integral vacuum filter row
Fluid valve.
Background technique
Vacuum filter is a kind of equipment for realizing separation of solid and liquid as motive force using negative pressure of vacuum.Negative pressure of vacuum (0.04-
Under the action of 0.07MPa), the penetration by liquid filter medium (filter cloth) in suspension is pumped, and solid particle is then by medium institute
Retention, to realize the separation of liquid and solid.It filters section in structure and arranges along horizontal length direction, can be continuous complete
At be filtered, washed, blot, the operations such as filter cloth regeneration.
The liquid filtered out enters the other side of filter cloth by negative-pressure vacuum, and enters Drainage tank, keeps in negative pressure
In the process, the separation process for persistently keeping vacuum, needs to carry out after liquid reaches a certain level drain, existing apparatus structure
It is the normal drain of work ability to be combined by vacuum valve and atmos-valve, but the collaborative work of two valves has delay
Effect, it is more in the locational space occupancy of the installation of vacuum filter and Drainage tank, it is unfavorable for structure and simplifies, and wastes material.
Summary of the invention
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of integral vacuum
Filter draining valve.
The technical scheme in the invention for solving the above technical problem is: including valve body, valve body is cylinder, side
Wall is closed structure, and side wall is provided with side and connects pipe, communicating pipe connected drainage tank upper cavity, in valve body
Upper end is provided with top cover, and driving structure is connected on top cover, and driving structure is connected with spool, the top cover to valve inner
On offer venthole, venthole is connected to the atmosphere outside of valve body, the spool is corresponding covers it is all on top cover
Venthole, and venthole is blocked or separated under the drive of driving structure, the lower end of the valve body forms snorkel, snorkel
The lower chamber of connected drainage tank, is provided with gap between the valve interior wall and the outer rim of spool, vacuum pressure passes through the gap
Reach balance.The present apparatus is a kind of structure in the corollary equipment Drainage tank of vacuum filter, for controllable rule
Discharge filtered fluid, by the valve body structure of original two kinds of valve cooperatings of needs, improvement is combined as a whole, and improves work
Response efficiency, improve the efficiency of processing, and installation space can be greatly decreased, reduce volume, simplify structure, save material
Material.In the present apparatus, valve body is main pressure control structure, and spool can pass through the interior pressure of the change control valve body of its station
Variation, is isolated when spool blocks venthole, in valve body with external pressure, and the upper cavity of Drainage tank itself is persistently
Negative pressure state, so also becoming the vacuum state of negative pressure in valve body, while the snorkel of lower end and the lower chamber of Drainage tank are
Directly it is connected to, so lower chamber is also vacuum, so in the state of upper and lower chamber pressure balance, the liquid meeting of upper cavity
Lower chamber is naturally flowed to, and is gradually increased in lower chamber liquid level, when the liquid level of lower chamber is raised to threshold value, the valve spool of valve of this structure
Station is replaced, outside atmosphere enters, balances the pressure of lower chamber, block between upper and lower cavity, and the leakage fluid dram of lower chamber is opened,
Be discharged liquid, back valve core playback, into circulation.The Drainage tank that this case is related to is existing equipment, and specific structure is not belonging to
The technical essential of this case, related technical personnel can voluntarily consult relevant file.This case just for valve design, it is involved
And relevant device description be design carry out technology explanation for this case, do not limit this case technical scope draw a circle to approve.
Further, the driving structure is that driving cylinder and telescopic rod, spool are connected on telescopic rod, telescopic rod and drive
Cylinder of taking offence connection, driving cylinder band movable valve plug move between top cover and ventilation tube edges.By telescopic rod and drive
The movement for cylinder control valve core of taking offence is suitble to use in the big environment of pressure difference.
Further, the part that the communicating pipe is connected to the upper cavity for the flow container that runs in is provided with airtight valve.It can be
The Temporarily Closed when vacuum degree deficiency of upper cavity makes quick pressure maintaining in upper cavity, improves efficiency.
Further, the surface of the spool is set as even curface, and is covered with close with top cover close contact
Sealing.Air-tightness can be improved in sealant, improves the safety of valve body.
Further, the driving structure be guide post and attract electromagnet, spool slidable adjustment in guide post, and by
Electromagnet attracts, and venthole is provided with multiple, and the surface that regularly arranged corresponding spool blocks.It can sealed by pressure difference
Attracted when blocking up with electromagnet and sealed, in release, since external air pressure height meeting nature pushes spool to generate gap, is suitble in sound
It is used in short scene between seasonable.
The utility model compared with prior art, has the following advantages that and effect: the present apparatus is a kind of in vacuum mistake
Structure in the corollary equipment Drainage tank of filter, for the discharge filtered fluid of controllable rule, by original two kinds of valves of needs
The valve body structure of cooperating, improvement are combined as a whole, and improve the response efficiency of work, improve the efficiency of processing, and
Installation space can be greatly decreased, reduce volume, simplify structure, save material.
