Abstract
The utility model provides a diaphragm type electromagnetic valve comprising a valve body, a valve cover, a diaphragm, a control spring and an electromagnetic mechanism, wherein the diaphragm is arranged between the valve body and the valve cover; the control spring is arranged between the valve cover and the diaphragm; the diaphragm is provided with a balance hole; the valve cover is provided with a connecting pipe extending into the inner cavity of the valve body; and the electromagnetic mechanism is arranged at the top end of the connecting pipe. The diaphragm type electromagnetic valve has the advantages that no wear is caused when the valve is opened and closed, the valve is not easy to be blocked by impurities and is quick to open and close and the like, and the service life of the diaphragm type electromagnetic valve is far longer than that of the traditional electromagnetic valve.
Description
Technical field
The utility model belongs to the electromagnetic valve structure field, particularly relates to a kind of diaphragm-type electromagnetic valve.
Background technique
Existing electromagnetic valve structure adopts piston sealing structure mostly, and the magnetic field that forms behind the coil electricity in the electromagnetic mechanism picks up moving iron core, and fluid floats piston, opens valve.During coil losing electricity, valve closing is fallen valve blockage in moving iron core and piston deadweight.This solenoid valve valve port directly contacts with electromagnetic mechanism, is stopped up by impurity easily, causes defective valve; In addition, the piston of this solenoid valve and piston cylinder produce very big friction, greatly reduce the life-span of valve.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can not stop up, and does not have wearing and tearing, and the diaphragm-type electromagnetic valve that is active in one's movements.
For achieving the above object, the technological scheme of employing is as follows:
A kind of diaphragm-type electromagnetic valve comprises valve body, valve gap, is installed in barrier film, the control spring between valve gap and barrier film, electromagnetic mechanism between valve body and the valve gap, described barrier film is provided with an equalizing orifice, described valve gap is provided with a connecting tube that stretches into body cavity, and described electromagnetic mechanism is arranged on the top of this connecting tube.
Described electromagnetic mechanism is made up of shell, lead, coil, skeleton, static iron core, moving iron core, spring, liner, described static iron core is arranged on the enclosure top, described moving iron core is located at the below of static iron core, be provided with spring between moving iron core and the static iron core, the outside of moving iron core is wound with coil, and lead is connected with coil and extends to housing exterior, and the bottom of moving iron core is provided with liner, described liner is corresponding with the inlet of connecting tube, and described skeleton is arranged on the below of shell.
The utility model also is provided with the hand switch that control electromagnetic valve opens and closes.
Described hand switch comprises cam, socket and handle, and described handle is by the rotation of socket control cam, and the jut of cam can contact with liner by rotating.
The utility model is made up of the barrier film between valve body, valve gap, valve body and the valve gap, control spring between valve gap and barrier film, barrier film is provided with equalizing orifice, valve gap is provided with the connecting tube that stretches into body cavity, and the top of connecting tube is provided with electromagnetic mechanism and hand switch.Electromagnetic mechanism is made up of the spring in shell, lead, coil, skeleton, static iron core, the moving iron core, the liner that is fixed on moving iron core bottom from outside to inside successively.Two ends of hand switch have cam, and an end has socket.Owing to this practicality novel is to utilize to change barrier film epicoele and valve and enter the cavity fluid pressure difference and obtain fluid and promote the opening and closing that barrier film upper and lower in-migration is finished sprue voluntarily, therefore not wearing and tearing fully, and reaction agility; Because valve port of the present utility model does not directly contact with electromagnetic mechanism, and the equalizing orifice size of barrier film is scalable, therefore effectively prevent the obstruction of impurity such as silt again.Do not have wearing and tearing when the utlity model has the valve open and close, be difficult for being stopped up, and advantage such as open and close agility, and the life-span is far longer than traditional solenoid valve by impurity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structure of the present utility model as shown in Figure 1, by valve body 13, valve gap 15, be installed in the barrier film 14 between valve body 13 and the valve gap 15, control spring 16 between valve gap 15 and barrier film 14 is formed, barrier film 14 has an equalizing orifice, valve gap 15 has the connecting tube 10 that stretches into valve body 13 inner chambers, the top of connecting tube 10 is provided with electromagnetic mechanism and hand switch 9, electromagnetic mechanism is from outside to inside successively by shell 3, lead 1, coil 2, skeleton 4, static iron core 5, moving iron core 7, spring 6 in the moving iron core 7, the liner 8 that is fixed on moving iron core 7 bottoms is formed, and the material of barrier film 14 is a silica gel material.
Working procedure of the present utility model is: when electromagnetic mechanism cut off the power supply, lead 1 no current passed through, coil 2 no electric circuits, and moving magnet 7 falls under spring 6 effects, and the liner 8 that is contained in moving iron core 7 ends is blocked and connecting tube is entered the mouth 17 also along with falling.This moment, by the pressure of the upper cavity pressure with barrier film 14 that good elasticity and flexible rubber makes greater than barrier film 14 cavity of resorptions, barrier film 14 falls rapidly under the tension force effect of this pressure difference and control spring 16, blocks the inlet of exhaust chamber 11, valve closing.When electromagnetic mechanism is switched on, electric current makes coil 2 also charged by lead 1, the magnetic field that coil 2 produces makes iron core 7 inhale mutually with static iron core 6, and spring 6 is compressed, and the rising of moving iron core 7 drives liner 8 and rises, liner 8 leaves and connecting tube enters the mouth 17, this moment, barrier film 14 epicoeles and exhaust chamber 11 were communicated with by connecting tube 10, and the pressure that enters chamber 12 inner fluids rises barrier film 14 greater than barrier film 14 epicoele hydrodynamic pressures, the fluid that enters chamber 12 directly passes through the inlet inflow and outflow chamber 11 of exhaust chamber 11, valve conducting.
The utility model Electromagnetic Control membrane valve can also be only with the opening and closing that manually come control valve.Liner 8 on the moving iron core 7 stops up connecting tube inlet 17, valve closing.Act on when external force on the socket of hand switch 9, and make hand switch rotate 180 °, the protruding part on the cam enters the mouth 17 with liner 8 tops from connecting tube, and at this moment, barrier film 14 epicoeles are communicated with exhaust chamber 11, then move the valve conducting on the barrier film 14.
