The interior clean hatch 44 and outer clean hatch 45 are the pointed hollow round table structure of right end, and interior clean hatch 44
Internal diameter is identical as the outer diameter of auxiliary rod 32, and the outer diameter of clean hatch is identical as the internal diameter of valve body 1.
The left end of the sliding block 41 is connected by cleaning spring 46 with the groove of 31 right side of sealing cover, the right side of sliding block 41
End is equipped with drawstring 47, and 47 right end of drawstring passes through sliding block 41 and close by wire casing around the deflecting roller 48 in solid circle 36
Capping 31 is pierced by from the lower end of valve body 1, and deflecting roller 48 is double grooved pulley；When work, when needing to clean valve body 1, unscrew
Dirt-discharging hook 15 pulls pull ring 49, and pull ring 49 is moved right by drawstring 47 with movable slider 41, thus with cunning is passed through on movable slider 41
The interior clean hatch 44 and outer clean hatch 45 that bar 42 and connection ring 43 are equipped with move right, the size and auxiliary rod 32 of interior clean hatch 44
Size match, the grease precipitated on auxiliary rod 32 can be struck off, the size of the size of outer clean hatch 45 and valve body 1
It matching, the grease that can be precipitated to 1 inner wall of valve body strikes off, and the grease struck off pushes to the right, since sealing station 51 stops,
Grease can enter sewage draining exit 12 by dirt discharge groove 14 from 1 lower end inner wall of valve body and be discharged, to realize grease type sediment in valve body 1
Cleaning.
The cleaning mechanism 6 includes the wiper ring 61 with the sliding connection of outer 45 right end circular groove of clean hatch, wiper ring 61
Cleaning spring 62 is installed between left side and circular groove inner sidewall, the left side of wiper ring 61 is symmetrical above and below to be equipped with cleaning rope 63,
Cleaning rope 63 connects in the middle part of sliding block 41 by wire casing and follows the trend of drawstring 47 before 1 lower end surface of valve body, valve body lower end
After be symmetrically arranged with seal receptacle 64.
The seal receptacle 64 includes the sealing ring 65 of 1 lower end inner wall of valve body, the structure phase of cleaning rope 63 and 47 lower end of drawstring
Together, the lower end of cleaning rope 63 is equipped with sealing valve 66, and the size upper end of sealing valve 66 is less than the size of sealing ring 65, and lower end is greater than
The size of sealing ring 65, the lower end of sealing valve 66 are equipped with pull rod 67；When work, after cleaning assemblies 4 clears up valve body 1, draw
Dynamic pull rod 67, under the action of cleaning spring 62, pull rod 67 drives wiper ring 61 to shake by cleaning rope 63, can will use knot
The outer clean hatch 45 of beam is cleared up, and prevents from remaining bulk shortening on outer clean hatch 45, while after all cleaning assemblies 4, to
Sealing valve 66 can be clamped closely knit, the leakproofness of guarantee valve body 1 by upper pushing drawing rod 67 with sealing ring 65.
Sliding block 41 in cleaning assemblies 4: being placed into rear snap-gauge 35 by control valve assembling first, then by rear snap-gauge 35 with
Preceding snap-gauge 34 is clamped, so that cleaning assemblies 4 in auxiliary rod 32, is then pushed in valve body 1 by sliding block 41, finally by valve deck 2
It is threadedly coupled with valve body 1, is completed so that entire control valve be spliced；
Valve body 1 normally conveys: edible oil being imported from oil inlet 11, since valve body 1 is in sealing state, is pressed on the left of valve body 1
Power can push to the left the sealing-plug 52 in left side after increasing, and oil inlet 11 is connected to oil outlet 13 at this time, to realize edible oil
Conveying；
Valve body 1 seals: after edible oil, which conveys, to be stopped, the pressure in 1 left side of valve body becomes smaller, in the effect of Packing spring 53
Under, sealing-plug 52 is moved to the left, at this point, the gasket 55 in seal groove 54 is bonded with sealing station 51, to increase sealing station
51 with the contact area of sealing-plug 52, not only reduced the frictional force of sealing-plug 52 but also improved the close of sealing-plug 52 and sealing station 51
Feng Xing extends the service life of sealing-plug 52；
Valve body 1 is cleared up: when needing to clean valve body 1, being unscrewed dirt-discharging hook 15, is pulled pull ring 49, pull ring 49 passes through
Drawstring 47 moves right with movable slider 41, thus with the interior clean hatch 44 being equipped on movable slider 41 by slide bar 42 and connection ring 43
It moves right with outer clean hatch 45, the size of interior clean hatch 44 matches with the size of auxiliary rod 32, can be on auxiliary rod 32
The grease of precipitating is struck off, and the size of outer clean hatch 45 matches with the size of valve body 1, can be precipitated to 1 inner wall of valve body
Grease is struck off, and the grease struck off pushes to the right, and since sealing station 51 stops, grease can be from 1 lower end inner wall of valve body by arranging
Dirty slot 14 enters sewage draining exit 12 and is discharged, to realize the cleaning of grease type sediment in valve body 1；
The cleaning of cleaning assemblies 4 is sealed with valve body 1: after cleaning assemblies 4 clears up valve body 1, pull rod 67 is pulled, in cleaning bullet
Under the action of spring 62, pull rod 67 by cleaning rope 63 drive wiper rings 61 shake, can will use the outer clean hatch 45 of end into
Row cleaning, prevents from remaining bulk shortening on outer clean hatch 45, while after all cleaning assemblies 4, and pushing up pull rod 67 can be with
Sealing valve 66 is clamped to closely knit, the leakproofness of guarantee valve body 1 with sealing ring 65.
Workflow in summary realizes the cleaning of control valve and the function that the good airproof performance service life is long, solves existing
The existing precipitation of grease existing in edible oils conveying of control valve causes control valve to block and can not clear up and spool and company
Port fits closely, and contact area is small, frictional force causes spool to damage greatly, leads to seal spool is poor and service life is short etc.
Problem has reached purpose.
The embodiment that the present invention only refers to drawing illustration is illustrated, it is believed that has related fields basic
The personnel of knowledge can carry out the other embodiments of diversified deformation and peer-level based on this.
