Embodiment
In order to more clearly the technical solution of the utility model can be understood, below in conjunction with accompanying drawing, the utility model is further illustrated.
The solenoid valve of a kind of Novel self-check break-make of the utility model as shown in Figure 1 to Figure 2, is grouped into by valve body part, do-part and flow inspection portion.
Described valve body is divided and is comprised valve body 01, diaphragm 02, end cap 05, spring 04 etc.Described valve body 01 is the main body of solenoid valve, and inside arranges fluid passage and lower chamber, flows to for fluid circulation and change.Valve body 01 arranges valve seat further, coordinates with the sealing iron block 03 on diaphragm 04, as the keying passage of electromagnetic valve switch.Valve body 01 arranges aperture further, coordinates with pilot hole 09 in end cap 05, as guide's gas channels.Valve body 01 two ends arrange flange 15 or screw thread is connected with pipeline.Described diaphragm 02 is the open-shut device of solenoid valve, is made up of flexible material, and middle part arranges sealing iron block 03, is driven can be produced switch motion by external force.It is upper and lower two-part that diaphragm 02 outer rim and valve body 01 compacting seal the compartition that valve body and end cap 05 are formed, and distribution forms upper cavity and lower chamber.Described end cap 05 is the closure member on solenoid valve top, arranges pilot gas channel orifices etc. further.Described spring 04, is positioned at the upper cavity on diaphragm 02 top, for solenoid valve diaphragm 02 provides pressure.
Described do-part comprises electromagnetic coil 07, iron core spring and movable core assembly 08 etc.Electromagnetic coil 07 is placed in solenoid valve top, is communicated with power supply by terminal box 06.Iron core spring and movable core assembly 08 form the little valve of guide, are placed in the column on end cap 05 top.The energising of electromagnetic valve coil 07 and power-off can drive movement or the falling of movable core 08, cause valve internal stream to change, thus the direct or indirect opening and closing causing valve.
Described flow inspection portion is divided and is comprised baffle plate 14, magnet, connecting rod 13, sensitive switch, upper shell 10 and lower shell body 12 etc.Flow testing fixture is placed in valve body 01 top of Way out, uses screw thread and valve body 01 to fix.Described baffle plate 14 is the rigid blades inserting solenoid valve fluid passage, direct and fluid contact, bears the active force of fluid flowing to it.Baffle plate 14 be arranged on further by connecting rod 13 be positioned at lower shell body 12 support on, connecting rod 13 the other end install magnet, connecting rod 13 arranges extension spring further, for reset.Described sensitive switch is single-pole double throw sensitive switch, and be placed in upper shell 10 inner, the wire of sensitive switch is connected to outside by terminal box 11.In described upper shell 10, connecting rod device and magnet being set further, responding action for carrying out magnetic force with lower shell body 12 internal magnet.Described upper shell 10 is two separate space with described lower shell body 12, makes electronic section completely isolated.
The utility model electromagnetic valve work process is: the sealing iron block 03 of solenoid valve diaphragm 02 by the pressure of spring 04 by valve body 01 inlet close.When entrance and outlet do not have pressure reduction, during energising, electromagnetic coil 07 produces electromagnetic force, directly opens the little valve of guide, and with sealing iron block 03 adhesive, diaphragm 02 is mentioned from valve seat 01, valve open.When entrance and outlet reach switch DP, after energising, electromagnetic force makes the little valve of the guide in end cap 05 open, main valve cavity of resorption pressure increase, and upper cavity pressure declines, thus utilizes pressure reduction that diaphragm 02 is upwards pushed open.Electromagnetic valve is opened.During power-off, electromagnetic force disappears, and spring 04 is pressed in diaphragm 02 on valve seat, valve closing.When pipeline is flow through in direction to fluid in accordance with the instructions, fluid forces baffle plate 14 deflects, and acts on associated latch mechanism by baffle plate 14, when deflecting into specified position, and sensitive switch action, output solenoid valve start signal.When do not have fluid by time, action of reset spring, makes baffle plate 14 reset, and then sensitive switch is discharged, the non-start signal of output solenoid valve.
Although described preferred embodiment of the present utility model, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the utility model scope.
