Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
The antifouling stifled entering water electromagnetic valve of one kind as shown in Figures 1 to 4, including inner sleeve 3 in shell 1, shell 1, set in inner sleeve 3
The sealing ring that spring 4 and iron core 5, the iron core 5 set stretch into the rubber core 6 being arranged on the end of valve inner, 1 inside of shell is installed
Frame component and sealing ring 8, sealing coil component and sealing ring 8 by shell 1 divide for back pressure chamber 10, intake chamber 11 and water-supplying chamber 12,
Sealing coil component include seal coil 7 and filtration ring net 13, seal the outer ring of coil 7 at least offer two lateral opening 71,
Filtration ring net 13 includes strainer portion 131 and interconnecting piece 132 and sealing ring 8 is equipped with and be connected to intake chamber 11 and lateral opening 71 and lead to
Water hole 80.
As shown in Figure 1, sealing coil 7 on increase a filtration ring net 13, inlet valve be opened and closed when, have partial impurities into
Enter back pressure chamber 10, therefore increasing filtration ring net 13 can effectively allow impurity or sediment to be precipitated other than filtration ring net 13,
It is blocked without coil 7 lateral opening 71 will be sealed, can effectively prevent accumulation of the impurity on lateral opening 71, in addition, prevented also from
Absorption of the bulk impurity on lateral opening 71 can effectively prevent the blocking of sealing coil 7, to prevent entering water electromagnetic valve because lateral opening
71 block caused failure, and electromagnetic coil 2 is equipped on the valve housing 1, and 2 endoporus of coil is equipped with inner sleeve 3, is equipped in inner sleeve 3
Spring 4, spring 4 times are equipped with iron core 5, and rubber core 6 is cased on iron core 5, sealing ring frame 7 is housed in shell 1, seals and is filled in coil 7
There are sealing ring 8, sealing ring 8, sealing coil 7 and 3 lower part of inner sleeve to form back pressure chamber 10,1 water outlet of shell has water cut off device 9, seals
9 top of the mouth of a river is close by forming water-supplying chamber 12 with 8 lower part of sealing ring, 8 lower plane of sealing ring sealing diameter inner point and water cut off device 9
8 outer ring of seal and shell 1,3 fitted seal of inner sleeve, prevent the leaked water of 1 inner cavity of shell, at 8 lower plane sealing of sealing ring inside
Intake chamber 11 is formed with 8 lower plane water cut off device of sealing ring, 9 outer ring and 1 inner cavity of shell, intake chamber 11 passes through 1 inner cavity lateral aperture of shell
Logical and external, external pressurized water can enter intake chamber 11 from this.
When coil 2 powers off, the rubber core 6 on iron core 5 and head is acted on by 4 pressure of spring to be pushed, by sealing ring 8, sealing
Coil 7 presses down and is sealed the mesoporous 70 for sealing coil 7 by rubber core 6, and sealing ring 8 is by intake chamber 11 and drip chamber at this time
Traffic channel cut-out, valve is closed, and the water of intake chamber 11 enters back pressure by sealing lateral opening the 71 of coil 7 at this time
Room 10, it is equal with the pressure of intake chamber 11 by pressure chamber in the pressure transmission to back pressure chamber 10 of intake chamber 11, and due to water-supplying chamber 12
Without pressure, then the upper applanation of sealing ring 8 is more than the pressure of lower plane, to make sealing ring 8 tightly be pressed on water shutoff
On mouth 9, valve is closed always.
As shown in Fig. 2, when coil 2 is powered, by the effect in magnetic field, iron core 5 is attracted and compressed spring 4, to make iron
Core 5 moves up, and 7 mesoporous 70 of sealing coil originally sealed is opened, by the high pressure water in pressure chamber by sealing 7 mesoporous of coil
70 flow in water-supplying chamber 12 and inlet valve are discharged；After part water is discharged in pressure chamber, by the pressure reduction of pressure chamber, intake chamber 11
Pressure ratio it is big by pressure chamber, to by sealing ring 8, sealing coil 7 up move, sealing ring 8 is detached with 1 water cut off device 9 of shell, into
Hydroecium 11 and drip chamber unicom, the water inlet of valve directly flows to drip chamber from intake chamber 11 and shell 1 is discharged, to make inlet valve beat
It opens.When valve is opened, when 5 rubber core 6 of iron core moves up, the water of intake chamber 11 still flows into back pressure chamber 10 from lateral opening the 71 of sealing coil 7,
The water of back pressure chamber 10 is flowed out by mesoporous 70.
As shown in figure 3, lateral opening 71 diameter is less than the diameter of mesoporous 70, when spool is opened, iron core 5 in sealing coil 7
6 ascending motion of rubber core is driven, the water in intake chamber 11 flows into back pressure chamber 10 from lateral opening the 71 of sealing coil 7, back pressure chamber 10
Water is flowed out by mesoporous 70, is to need to make sealing ring 8 and sealing coil 7 that could keep electricity in elevated position always under this state
Magnet valve works normally, if lateral opening 71 diameter is more than the diameter of mesoporous 70, water will quickly flow into back pressure chamber 10, lead
Cause back pressure chamber 10 in hydraulic pressure be more than intake chamber 11 hydraulic pressure, sealing ring 8 and sealing coil 7 always tightly be pressed on water cut off device 9
On, valve would be at closed state, cannot achieve the circulation of water.
As shown in figure 4, filtration ring net 13 includes strainer portion 131 and interconnecting piece 132, strainer portion 131 is by several for filtering
The filter mesh of fluid impurity and sediment forms, and strainer portion 131 is connected with interconnecting piece 132 " L " type, and strainer portion
131 and interconnecting piece 132 be structure as a whole, the both ends of interconnecting piece 132 respectively with the outer wall of sealing coil 7 and the table of sealing ring 8
Face is tightly connected, the sundries that the filter mesh in strainer portion 131 can will be flowed into the water in back pressure chamber 10 in intake chamber 11
And sediment be blocked in it is outer, in this way, sundries and sediment can not on lateral opening 71 accumulated plugging lateral opening 71, and interconnecting piece
132 can be good at playing the role of sealing, ensure under valve body closed state, and the water in intake chamber 11 can only pass through lateral opening 71
It is flowed into back pressure chamber 10, avoids the generation of unnecessary water stream channel, and 13 structure of filtration ring net of integral structure is strong
Degree is stablized, and the service life is longer.
As shown in Figure 1 or 2, sealing ring 8 is equipped with the limbers 80 of connection intake chamber 11 and lateral opening 71, on sealing ring 8
Limbers 80 can realize the circulation of water in intake chamber 11 and back pressure chamber 10.
Water shutoff column is equipped in shell 1, water shutoff column is embedded the water cut off device 9 that sealing is formed in sealing ring 8, and water cut off device 9 is located at
80 inside of limbers, in a valve-closed state, the hydraulic pressure being more than in intake chamber 11 by the hydraulic pressure of back pressure chamber 10 will be close for water cut off device 9
Seal 8 is pressed firmly against in water shutoff column, and water shutoff column is embedded the water cut off device 9 for being formed and being sealed in sealing ring 8 and has blocked intake chamber
11 with the circulation of 12 water of water-supplying chamber.
The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art
Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Range.
