Description
Technical field
The utility model relates to solenoid valves.
Background technique
Dynamic iron core is lifted by static iron core actuation when electromagnetic valve coil is powered, and opens valve, and static iron core loses magnetism when power-off,
Dynamic iron core, which resets, under the action of the spring closes valve, must be powered always in duration of valve opening section coil, consume electric energy always, this is
A kind of monostable solenoid valve.Monostable solenoid valve power consumption is more, especially connects in no cable, needs battery-powered feelings
Under condition, the change Fei Geng great of power consumption.Solenoid valve gives coil one electric pulse, and dynamic iron core is attracted by static iron core and opens valve, electric arteries and veins
Punching terminates, and dynamic iron core is still attracted by static iron core, is not necessarily to power consumption in duration of valve opening section, when valve closing gives coil one reverse phase electric pulse, moves
Plunger return closes valve, this is a kind of bistable electromagnetic valve, since electrical pulse time is extremely short, about a few tens of milliseconds, therefore bistable state
Solenoid valve can significantly power saving.A kind of bistable electromagnetic valve that document CN101551024A is disclosed is multiple in static iron core rear end face
Unify permanent magnet, static iron core obtains magnetic and is attracted dynamic iron core when coil is powered, when coil blackout, the static iron core quilt under permanent magnet effect
Magnetization is attracted dynamic iron core, and duration of valve opening section coil is without being powered.When valve closing, one reverse phase electric pulse of coil is given, static iron core generates anti-
It to polarity magnetic force, is acted in conjunction with spring, dynamic iron core resets.The prior art is installed since permanent magnet superposed type is arranged and occupy-place,
It only can be used as bistable electromagnetic valve, be unable to dual-purpose as monostable solenoid valve, unparalleled/Dan Shiyong, dual-purpose cannot need
The applications of monostable solenoid valve.
Summary of the invention
It is single that the utility model will solve bistable electromagnetic valve application in the prior art, cannot be in monostable electromagnetism
The problem of valve application is applied, provides a kind of bistable electromagnetic valve of the utility model thus, and this bistable electromagnetic valve is double/
Single dual-purpose only easily need to slightly do adapter increase and decrease, can just become bistable electromagnetic valve, and can become monostable solenoid valve,
Full adaptation as solenoid valve application.
To solve the above problems, the technical solution adopted in the utility model is that have including valve body, valve deck and by bracket bottom
The electromagnet that plate, bracket, coil rack, coil and iron core are constituted, the iron core lower section are equipped with piston, the iron core and piston position
In in the center sleeve of coil rack, the bracket bottom plate is incorporated into above valve deck, it is characterized in that offering on the valve deck recessed
Platform is provided with magnet in the concave station, and the concave station and magnet are corresponding with the center sleeve lower part and piston lower portion.
The preferably described concave station is annular concave platform, and the magnet is annular magnet.
The more preferably described magnet is the annular magnet being made of two half-ring-shaped magnets.
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the outline drawing of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Label and counterpart in figure: 1 bracket bottom plate, 2 coils, 3 brackets, 4 coil racks, 4-1 center sleeve, 5 iron cores, 6
Spring, 7 pistons, 8 magnet, 9 piston caps, 10 water outlets, 11 diaphragms, 12 guide valve seats, 13 back pressure chambers, 14 diaphragm plates, the side hole 14-1,
15 main valve seats, 16 water inlets.
Specific embodiment
A kind of bistable electromagnetic valve, valve body are equipped with water inlet 16, water outlet 10 and main valve seat 15, are combined on main valve seat 15
Flap, the flap are made of diaphragm plate 14 and diaphragm 11, and diaphragm plate 14 is above and valve cover portion forms back pressure chamber 13, diaphragm plate 14
On be provided with side hole 14-1, side hole 14-1 runs through back pressure chamber 13 and intake antrum respectively above and below.Valve deck is equipped with guide valve seat 12, valve deck
It is connected with bracket bottom plate 1 above, bracket 3 is connected on bracket bottom plate 1, coil rack 4 and thereon set coil 2, line are equipped in bracket 3
It is equipped with iron core 5 and piston 7 in the center sleeve 4-1 of ring framework, spring 6 is equipped between iron core and piston, 7 lower end of piston is connected with work
Cock cap 9, piston cap 9 is corresponding with guide valve seat 12, and the lower part center sleeve 4-1 is located in the cavity of valve deck, on the cavity of valve deck
Portion is equipped with the annular concave platform radially extended out, is provided with magnet 8, the annular concave platform and magnet 8 and center on the annular concave platform
The lower part pipe 4-1 and 7 lower part of piston are corresponding to be simultaneously overlapped with center sleeve and piston axis, and the magnet 8 is annular magnet, it can be with
It is made of two half-ring-shaped magnets, embraces and enclose in the lower part center sleeve 4-1.
Give coil 2 one electric pulse, iron core 5 is magnetized, and piston 7 is lifted by the actuation of iron core 5, and piston cap 9 leaves guide valve seat 12,
Guide valve seat 12 is opened, and the water in back pressure chamber 13 is flowed out by guide valve seat 12,13 pressure release of back pressure chamber, causes to be greater than back into water cavity pressure
Pressure chamber pressure is lifted by the flap that diaphragm plate 14 and diaphragm 11 are constituted, and main valve seat 15 is opened.After the electric pulse, due to
The effect of magnet 8, piston 7 are magnetized, and piston 7 and iron core 5 are still pulled together, and guide valve seat 11 is still opened, and main valve seat 15 is also opened
It opens, is being not necessarily to be powered after rear duration of valve opening section coil 2.
After above-mentioned state, 2 one reverse phase electric pulse of coil is given, iron core 5 obtains polarity phase anti-magnetic, it is acted in conjunction with spring 6,
Piston 7 is depressed, and guide valve seat 11 is closed, and the water that 14-1 enters back pressure chamber 13 from side hole cannot be discharged, and back pressure chamber pressure rise is arrived
Suitable with water inlet cavity pressure, it is suitable that the flap corresponds to main valve seat peripheral part above and below pressure, and flap corresponds to main valve
Surface pressure is greater than lower surface pressure on seat channel part, and suffered gross pressure is greater than following suffered gross pressure above flap, and flap pushes,
Close main valve seat 15.
Positive and negative two electric pulses realize the open and close of this solenoid valve, and the opening time, section coil was without being powered.
The utility model is provided with magnet 8 in the concave station described in valve deck, becomes bistable electromagnetic valve, removal magnet,
For monostable solenoid valve, placement and removal except magnet, the two components and be combined with each other relationship and spatial relation completely without
Variation.The placement of magnet 8 is very convenient with removal, and the annular magnet being especially made of two half-ring-shaped magnets is more such.This is practical
The novel dual-purpose with bistable state, monostable solenoid valve, application is wide, enormously simplifies bistable state, monostable solenoid valve
The operation program such as the manufacturing, storage and transportation, application configuration and cargo handling operation, generally save the cost, reduce waste.
