Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Shown in Fig. 1,2,3, pump intake automatic dirt cleaning device, including：First water inlet pipe 1, its water inlet are equipped with fair
Perhaps the first screen pack 4 that the fluid of small foreign body passes through is included；Decontamination orifice 2, the soil cleaning port 5 of its water inlet are equipped with more than front and rear
The pressure valve 51 that can be automatically opened up after threshold pressure differential；First screen pack 4 generates fair with soil cleaning port 5 because of opposed installation
Perhaps it is less than the safety clearance 6 that the foreign matter of fixed dimension enters；Second water inlet pipe 3, the water outlet of its water inlet and the first water inlet pipe 1
Mouth, the delivery port of decontamination orifice 2 constitute three-way pipe structure；Enter inside second water inlet pipe 3 provided with from the first water inlet pipe 1
Enter after the fluid realization shunting of second water inlet pipe 3 and inversely the dividing plate 7 of decontamination orifice 2, inversely enter the fluid of decontamination orifice 2 described
Flow range in decontamination orifice 2 on be also equipped with the filtering mesh number of Y types strainer valve 8 and the filtering net of strainer valve 8 and be more than described the
The mesh number of one screen pack 4.Further, the water side of second water inlet pipe 3 connects with water pump suction inlet.When in use,
After first being installed in advance according to structure, after then the delivery port of the second water inlet pipe 3 and the suction inlet of water pump are connected again.Start
The motor of water pump, due in sequence：The spacing distance of safety clearance 6, the first screen pack 4, the aperture diameter of the filter screen of strainer valve 8
Taper into, therefore after water pump opening, extraneous water source and solid foreign materials can first pass through first of safety clearance 6 mistake
Filter, even if so there is the foreign matter being much relatively large in diameter in the front end of the first water inlet pipe 1, this safety clearance 6 can also block diameter
Very big solid dirt enters inside the water inlet of the first water inlet pipe 1 relatively, when the foreign matter less than the diameter of safety clearance 6 enters peace
Behind full gap 6, now also further to be filtered by the first screen pack 4, the fluid that can pass through will be directly well by water
Impeller of pump is transferred to destination locations, and can be temporarily because the situation absorption of negative pressure exists by the foreign matter that the first screen pack 4 stops
On first screen pack 4.With pump working usage time it is long after, foreign matter can be more and more on the first screen pack 4, now exist
In the case that the power of water pump is constant, such case is exactly that the covert water inlet bore for causing the first water inlet pipe 1 diminishes, and then
So that bigger pressure differential state is in for the hydraulic pressure of the both sides of boundary with the first screen pack 4 blocked by foreign matter.
At this moment wait, when the very big of the differential water pressures in the hydraulic pressure in the second water inlet pipe 3 and external world change and reach pressure valve 51
After the threshold value automatically opened up, the unexpected opening of pressure valve 51 will be promoted, at this time due to the water inlet of the first water inlet pipe 1 and clear
The water inlet of dirty pipe 2 is the first screen pack 4 to placement location, and on the first water inlet pipe 1 by the situation of Severe blockage；Therefore meeting
So that decontamination orifice snap back siphons away the foreign matter on the first screen pack 4, the purpose of the first screen pack 4 of cleaning is so achieved that.
When Given this, pressure valve 51 causes the pressure in the second water inlet pipe 3 to diminish with ambient pressure difference after opening, and has been less than pressure again
The threshold value that power valve 51 is opened, so automatic close.
In above-mentioned workflow, as long as the second water inlet pipe 3 is more than the threshold value of the opening of pressure valve 51 with extraneous pressure differential,
Exactly automatically open up and reversely siphon away the foreign matter temporarily retained because of negative pressure on the first screen pack 4, until on the first screen pack 4
Foreign matter seldom without prejudice to untill when the normal work of water pump.Due to being provided with Y types strainer valve 8 inside decontamination orifice 2 and filtering
The filter screen mesh number of valve 8 is more than the mesh number of the first screen pack 4, therefore foreign matter can enter in strainer valve 8, while also can be thinner by mesh
What is caused is retained by strainer valve 8, now, because the hydraulic pressure of the both sides of pressure valve 51 on decontamination orifice 2 can also tail off, will close automatically
The water-flowing path of decontamination orifice 2 is closed, is not reversed also and siphons away if the first screen pack 4 of the first water inlet pipe 1 is foreign matter, then be clear
Pressure valve 51 on dirty pipe 2 also may proceed to open, and so relative to the foreign matter of an obstinate attachment of comparison, will pass through pressure valve
51 constantly automatically open up and close, the continual dirt that cleaning attachment is constantly stirred using liquid, until cleaning completely
It is clean and reach certain and allow by hydraulic pressure, so as to ensure the water pump work well by the fluid of the first water inlet pipe 1.
Simultaneously after the closing of pressure valve 51, the fluid in decontamination orifice 2 is in the state of geo-stationary, therefore plus dividing plate
After 7, be achieved that realizes shunting the fluid for flowing through the first water inlet pipe 1 and the second water inlet pipe 3, and the fluid shunted away can be straight
It is reversed to impacting the foreign matter that is momentarily jammed on the Inner filter net of strainer valve 8, due to this filter screen after the opening of pressure valve 51 in just
To flowing, the space that a part of foreign matter stops filter screen can be produced, therefore reverse impact will reach mistake in cleaning strainer valve 8
The purpose of filter screen and other positions that the foreign matter that drops will enter in strainer valve 8, realize collection and memory card are first
The purpose of foreign matter on screen pack 4.
Further, several the also evenly distributed through hole shapes of front end of pressure valve 51 installed in the decontamination orifice 2 are entered
Dirty hole 52.If in reality in use, simply can simply be gone out using the bore absorption foreign matter of a complete decontamination orifice 2
The ineffective situation of foreign matter is now reversely absorbed, as long as because it can also adsorb away entirety when reverse adsorption foreign matter
The water source of the decontamination orifice 2 of circular bore, it is smaller just real so to result in the adsorption capacity time together with the absorption simultaneously of water source and foreign matter
Show pressure differential to reduce, so causing the reduction of actually active cleaning efficiency.Therefore dirty hole 52 is entered plus manhole, just
It can targetedly, comprehensively be covered on each area of the screen pack 4 of the first water inlet pipe 1 first, reach absorption efficiency more
Bigization.When adsorption of foreign matter is needed, walked because foreign matter enters the autotelic absorption in dirty hole 52 by less several of bore, no
The time of pressure differential reduction can only be extended, also extend and reversely siphon away the dirty time, bigbore removed contamination compared to more single
Mode, there is more efficient clean-up capability.
Further, it is described enter the dirty front end of hole 52 be equipped with it is horn-like and be easy to siphon away be attached to it is different on the first screen pack 4
The dirt collection cover 53 of thing.Because the installation for entering dirty hole 52 is only that big circular aperture is become small diameter, therefore, in order to realize
The ability of more efficient absorption foreign matter, therefore dirt collection cover 53 is added, so after the dirt collection cover 53 of horn-like structure works, meeting
More fully, the foreign matter on bigger the first screen pack of reverse absorption 4 of pressure.Main operation principle is due into dirty hole 52
After bore diminishes, entering dirty hole 52, only for face to enter foreign matter adsorption capacity on dirty hole 52 high, elsewhere adsorption capacity due to
Coverage rate is smaller, causes absorption not comprehensive, thus dirt collection cover 53 due to provided with horn-like structure, therefore can be very good just to solve
Certainly above mentioned problem.
Further, it is equipped with the pressure valve 51 so that the fluid of decontamination orifice 2 that inversely enters is in the first water inlet pipe 1
The through hole 511 of reverse flow.In actual use, due to hydraulically full in decontamination orifice 2, and it is in pressure valve 51 and closes shape
After state, such liquid is mostly in inactive state, the filtering hit for shunting the fluid inversely come in recoil in strainer valve 8
Net can produce larger obstruction, have impact on the cleaning capacity of the filter screen on strainer valve 8, therefore by increasing the reverse flow
Through hole 511, due under the environment after less than differential water pressures threshold value, there is great impact energy due to shunting the fluid inversely come in,
It is far longer than the Fluid pressure come in by the through hole 511, so in the Fluid pressure inversely shunted and passing through the through hole
After the fluid body difference that the 511 positive Fluid pressures flowed into are subtracted each other, the filtering on this hydraulic pressure impact filtration valve 8 is utilized
Net.This structure is not only provided with circulation for the shunting fluid inversely come in, also with efficient cleaning purpose,
Therefore the purpose of the screen pack reversely on cleaning strainer valve 8 is realized.
Further, the dividing plate 7 is arc plate structure, and the depressed area of arc is towards the position of decontamination orifice 2, due to arc
The radian of shape plate 7 is identical with the radian of decontamination orifice 2, thus will not produce shunting after flow after current deformation, and then
The energy of screen pack on current entirety impact filtration valve 8 will not be reduced, improve the ability of reversely cleaning foreign matter.
Decontamination orifice 2, first water inlet pipe 1 of the utility model by opposed water inlet, realize normal water suction and remove
Two workflows of dirt.Simultaneously using the screen pack in the fluid reverse impact strainer valve 8 in the first water inlet pipe 1 of shunting, reach
To the reverse purpose for collecting foreign object in pipe rubbish of removing contamination.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
