Specific embodiment
Below in conjunction with the accompanying drawings the slow specific embodiment closing pilot-type solenoid valve of the present invention is described further.
As shown in accompanying drawing 1~5, a kind of slow close pilot-type solenoid valve, include flexibility valve element 1, choke 2, epicoele sleeve 3,
Back-moving spring 4, solenoid 5 and dynamic iron core 6, the upper port of epicoele sleeve 3 is closed, and its lower port is open-like shape, electromagnetism
Coil 5 wraps up the top half of epicoele sleeve 3, arranges back-moving spring 4 and dynamic iron core 6, dynamic iron core in epicoele sleeve 3 from top to bottom
6 lower end is fixedly installed sealing gasket 12, is provided with flexible valve element 1, epicoele sleeve 3 and flexible valve at the lower port of epicoele sleeve 3
Core 1 surrounds and forms valve element epicoele 7, and flexible valve element 1 is provided with pilot valve hole 10 and balance pipe 11, pilot valve hole 10 and balance pipe 11
Upper end all connect valve element epicoele 7, the lower end connection outlet primary valve 9 in pilot valve hole 10, outlet primary valve 9 connects described slow close first
The outlet of conductivity type electromagnetic valve, the lower end of balance pipe 11 connects entrance primary valve 8, and entrance primary valve 8 connects described slow pass guide
The water inlet of type electromagnetic valve, in solenoid 5 no power, described sealing gasket 12 closes pilot valve hole 10, in described balance pipe
Setting choke 2 in 11.
Define the valve closing time be electromagnetic valve be cut off power the moment thoroughly cut off between the current moment to electromagnetic valve
Time.
As shown in Figure 5, minim gap is set between choke 2 and balance pipe 11, and the cross-sectional area in this gap is much smaller than
The cross-sectional area in pilot valve hole 10, and the cross-sectional area in this gap is not more than the one thousandth of the area of valve element 1 upper surface, wherein valve
Core 1 upper surface refers to valve element 1 surface being in valve element epicoele 7, is amassed by arranging this clearance cross section, can make of the present invention
Valve closing time of slow pass pilot-type solenoid valve reach time several seconds, make valve element 1 lentamente close outlet port 9, also
It is lentamente to block current, effectively reduce or even eliminate hydraulic blow when closing valve.
As shown in Figure 1, although the slender space of receiving back-moving spring 4 and dynamic iron core 6 is a part for valve element epicoele 7,
But this partly affects less on the acting characteristic of valve, so ignoring the impact of this part, in the figure, the height H of mark is
The effective depth of valve element epicoele 7, the space of corresponding valve element epicoele 7 is the useful space of valve element epicoele 7, the length of choke 2
Not less than effective depth H of valve element epicoele 7, so that choke 2 will not fall in valve element epicoele 7 completely leaves balance pipe 11.
One end being in valve element epicoele 7 of choke 2 is bending, so that choke 2 will not fall into inlet valve completely
Mouthfuls 8 and leave balance pipe 11.
Choke 2 is rustless steel, plastics or other resistant material make, in case damage choke 2 or resistance because of corrosion
Plug balance pipe 11.
Flexible valve element 1 is rubber membrane, plastic foil or the combination of the two, and described rubber membrane is soft rubber membrane, utilizes
The flexible deformation of flexible valve element 1 realizes being turned on and off exporting primary valve 9.
As shown in Figure 4, when the combination that described flexibility valve element 1 is using rubber membrane 14 and plastic foil 13, described moulds
Material film 13 can be duroplastss, and plastic foil 13 is arranged on the top of rubber membrane 14 near valve element epicoele 7 side, pilot valve hole 10 peace
Weighing apparatus hole 11 is arranged on plastic foil 13.
Of the present invention slow close pilot-type solenoid valve operation principle be:
As shown in Figure 1, now solenoid 5 is not energized, and dynamic iron core 6 is in the presence of deadweight and back-moving spring 4
Make sealing gasket 12 confined bed valve opening 10, the water at entrance valve port 8 enters on valve element through the gap between choke 2 and balance pipe 11
Chamber 7, now the pressure in valve element epicoele 7 be more than outlet port 9 at pressure so that valve element 1 closing outlet port 9, block
Current, valve is closed.
As shown in Figure 2, after solenoid 5 is energized, dynamic iron core 6 overcomes back-moving spring in the presence of electromagnetic attraction
4 elastic resistance and move up so that sealing gasket 12 opens pilot valve hole 10, valve element epicoele 7 passes through pilot valve hole 10 and outlet
Valve port 9 connects, the reduced pressure in valve element epicoele 7, and the water in valve element epicoele 7 passes through pilot valve hole 10 flow inlet and outlet valve port 9, entrance
At valve port 8, the pressure of water is more than pressure in valve element epicoele 7 and direction upward, thus promoting valve element 1 to produce bending deformation upwards
Shape, makes valve element 1 open outlet port 9, and water enters outlet port 9 from water inlet through entrance valve port 8, finally flows out from outlet,
Direction as indicated by curved arrow in accompanying drawing 2, valve is in opening.
After solenoid 5 power-off, dynamic iron core 6 moves down in the presence of deadweight and back-moving spring 4, and then makes sealing
Pad 12 confined bed valve opening 10, now the pressure in valve element epicoele 7 is more than the pressure at outlet port 9, the water warp at entrance valve port 8
Gap between choke 2 and balance pipe 11 enters valve element epicoele 7, promotes valve element 1 to produce downward deflection deformation, due to throttling
Gap very little between bolt 2 and balance pipe 11, enters the discharge very little of valve element epicoele 7, through certain time delay through this gap
After time, valve element epicoele 7 can be filled to the state making valve element 1 close outlet port 9, that is, lentamente blocks water
Stream, valve is closed, that is, state as shown in Figure 1 is that is to say, that extend slow pass guide of the present invention
The valve closing time of type electromagnetic valve.
By arranging the different gap value between choke 2 and balance pipe 11, the different valve closing times can be obtained,
Actual measurement shows, the valve closing time can easily reach 15 seconds, when the valve is closed between not any for pipeline when 3 seconds about
Hydraulic blow.
Further, the described valve closing time is relevant with the hydraulic pressure in pipeline, and the hydraulic pressure in pipeline is lower, during valve closing
Between longer, when the hydraulic pressure value in pipeline is reduced to certain value, valve can not reliably be closed, so slow pass of the present invention
Pilot-type solenoid valve is applied to certain hydraulic pressure,
During described valve element 1 is turned on and off outlet port 9 and when having water to flow through valve, choke 2 meeting exists
Move up and down in balance pipe 11 or vibrate, especially during closing valve, this vibration is the most violent, can effectively prevent
Minim gap between dirt silt resistance choke 2 and balance pipe 11 in sealing.
If the cross-sectional area reducing balance pipe 11 simply and do not use choke 2, on the one hand can make balance pipe 11
Processing technique require higher, on the other hand, at work balance pipe 11 easily by water dirt become silted up resistance and cannot reliably close
Valve closing door.
Finally, the slow technical scheme closing guide electromagnetic valve of the present invention is also applied for the slow pass control to other fluids
System, reaches effective purpose eliminating fluid impact when closing valve.
Certainly, in the case of the framework without departing from the present invention, can also there is other selection and development and our energy
Enough it is envisioned that equivalent device.
