As shown in figure 4, spool 4 is equipped with the first valve core tube 41 and the second valve core tube 42, the second valve core tube 42 is set to the first valve
The top of core pipe 41 and it is equipped with partition 43 between the two, partition 43 will be on the internal channel of the first valve core tube 41 and the second valve core tube 42
Under separate, the diameter of the first valve core tube 41 is greater than the diameter of the second valve core tube 42.The top of first valve core tube 41 is along its circumference side
Extend outwardly to the bottom for being equipped at least one valve core channel 44, the first valve core tube 41 equipped with annular brace platform 45.
The top of second valve core tube 42 is arranged with top plate 46, between top plate 46 and the second valve core tube 42 along the circumferential direction uniformly
Equipped with 3 gaskets 47, the outside positioned at the gasket 47 of 46 lower section of top plate is equipped with protrusion 48.Gasket 47 is preferably elastomeric pad.
As shown in figure 5, valve pocket 5 is equipped with valve sleeve 51, the lower part of valve sleeve 51 is equipped at least one valve along its circumferencial direction
Cover channel 52.The top of valve sleeve 51 is equipped with card slot 53, matches for the protrusion 48 with spool 4.The top of valve pocket 51 is along it
Circumferencial direction is equipped with supernatant stencil plate 54, and the outer diameter of supernatant stencil plate 54 is identical as the internal diameter of oil pipe 1.The bottom of valve pocket 51 is along its circumference
Direction is equipped with lower wax removal plate 55, and the maximum outside diameter of lower wax removal plate 55 is identical as the internal diameter of oil pipe 1.Preferably, lower wax removal plate 55
Its circumferencial direction of outer periphery is equipped with lower wax removal board slot 56, can reduce the contact surface between 1 inner wall of lower wax removal plate 55 and oil pipe
Product, to reduce frictional force, makes paraffin valve more smoothly move up and down in oil pipe 1.
Valve pocket 5 is sheathed on the periphery of spool 4, and specifically, the internal diameter of valve pocket 5 is identical as the outer diameter of the first valve core tube 41,
The bottom of valve pocket 5 is set to the top of annular brace platform 45, and top plate 46 is set to the over top of valve pocket 5.
As shown in fig. 6, reset magnet 3 is annular, it is fixed on pedestal 31, pedestal 31 is fixed on the inner circumferential bottom of oil pipe 1
Portion is equipped with oil passage 32 among it.
As shown in Figure 7 and Figure 8, valve opening mandril 2 is equipped with ring body 21, and the inner circumferential of ring body 21 is equipped with connecting rod 22,
The bottom of connecting rod 22 is equipped with jacking block 23.The length d of jacking block 23 is greater than the internal diameter of the second valve core tube 42.
The course of work of the utility model is described in detail below.
In original state, paraffin valve sinks to the bottom of oil pipe 1, as shown in Fig. 2, the bottom of valve pocket 5 is supported on 4 bottom of spool
Annular brace platform 45 on, valve core channel 44 and valve pocket channel 52 are located at that position, the two are simultaneously not communicated with one on the other.When latent oil electricity
When pump is started to work, crude oil is entered inside the first valve core tube 41 by the oil passage 32 among pedestal 31, due to the first valve
Valve core channel 44 in core pipe 41 is blocked by valve sleeve 51, and crude oil enters after the first valve core tube 41 there is no other outlet, can only
Heading on partition 43 slides entire paraffin valve upwards, and paraffin valve at this time can be regarded as a plunger, the supernatant in slipping
Stencil plate 54 and lower wax removal plate 55 gradually scrape off the paraffin being bonded on inside pipe wall.
When spool 4 reaches top, after the top plate 46 on spool 4 is in contact with the jacking block 23 on valve opening mandril 2, spool 4 by
Blocking to valve opening mandril 2 no longer moves up, at this point, the bottom that oil liquid heads on valve pocket 5 makes valve pocket 5 continue to move up, valve core channel 44
It is gradually connected to valve pocket channel 52, until the card slot 53 at 5 top of valve pocket is stuck in protrusion 48, as shown in figure 3, at this point, 4 He of spool
Valve pocket 5 forms a fixed entirety, and valve core channel 44 is connected to completely with valve pocket channel 52, and oil liquid is in the first valve core tube 41
It is exported afterwards after sequentially passing through valve core channel 44, valve pocket channel 52 across supernatant stencil plate 54 (supernatant stencil plate 54 is equipped with logical hydraulic fluid port).
In this way, oil liquid conveying is gradually stable after oil circuit is unimpeded, at this point, entire paraffin valve is slow under the action of self-weight
Decline, when reaching 1 bottom of oil pipe, spool 4 and valve pocket 5 are still integrated, and valve core channel 44 and valve pocket channel 52 are still kept unimpeded
State, about 1 oil pipe keep clear.
When needing wax removal, closes submersible electric pump and (be equipped with controller, controller and 3 phase of reset magnet in submersible electric pump
Even), at this point, controller control reset magnet 3 is powered and generates magnetic force, reset magnet 3 is downward by valve pocket 5 by the magnetic force of itself
It inhales, so that card slot 53 is disengaged from protrusion 48, valve pocket 5 is displaced downwardly to its bottom and comes back on annular brace platform 45, valve core channel
44 and valve pocket channel 52 be in disconnected state, reopen submersible electric pump, controller controls reset magnet 3 and powers off, and fluid power is again
Paraffin valve is pushed to move up wax removal, this movement repeats, and wax removal frequency can be adjusted according to the speed of wax deposition, whole process is only
It needs to switch submersible electric pump, is not necessarily to other operations.
Using gasket 47, the engaging machine of protrusion 48 and card slot 53 between valve pocket 5 and the second valve core tube 42 in the utility model
Structure allows spool 4 and valve pocket 5 to become a fixed entirety, can also with other any type of existing structures, and only needing can
Make to achieve the purpose that between them engaging and separated.The common controllers such as PLC can be selected in controller in submersible electric pump
It can.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope,
It should still belong to the scope that the utility model claims book is covered.
