Abstract
A miniature low-voltage electromagnetic valve without leakage is composed of a valve body with top valve opening, a valve cover installed to valve body, a coil skeleton installed onto valve cover and with a movable armature in it, and a coil arranged on coil skeleton. It features that a pressing pad on said valve opening has a through hole through which said movable armature passes, and a spring with one end connected with said pressing pad is arranged at valve opening to surround said armature.
Description
Technical field
The present invention relates to a kind of solenoid valve, belong to electromagnetism optimal design field.
Background technique
At present, existing solenoid valve on the China market comprises part from the solenoid valve of external introduction, exists that volume is relatively large, starting resistor is higher relatively, connect the easy seepage of interface of solenoid valve and use the not tight defective of sealed mouth for a long time.The reason that these problems and defective exist is: 1. the material material of Shi Yonging can not meet the requirement of its flowing medium; 2. be used to the long-term stressed and dielectric corrosion easy deformation of the rubber that seals; 3. relatively large its structural design of solenoid valve volume is unreasonable.
Micro leak-free low voltage electromagnetic valve adopts compact structure from the theory of " medium is not reported Lou ", has overcome the defective that existing solenoid valve exists.Utilize the flexible elastic force of pipeline self to realize break-make control.Micro leak-free low voltage electromagnetic valve is applied in Environmental Conditions and service condition requires very harsh occasion, is characterized in that nothing is leaked (ducted medium does not obtain break-make control by the interface of solenoid valve), low voltage, volume is little.Can be applied in Aero-Space military field and scientific research, industrial field widely.
Summary of the invention
Goal of the invention of the present invention is in order to realize the microminiaturization of solenoid valve volume, to avoid leakage problem occurring in the flowing medium conduction process.
Technological scheme of the present invention is as follows: a kind of micro leak-free low voltage electromagnetic valve, comprise valve body, valve gap is installed on the valve body, on valve gap, be installed with coil rack, coil is installed on the coil rack, be provided with moving armature in the coil rack, it is characterized in that, the top of valve body is provided with valve port, and the valve port upper fixed is equipped with compress gasket, and compress gasket is provided with the through hole that can pass moving armature, the valve port place is provided with an end and is fixed on spring on the compress gasket, the internal diameter of spring is greater than the external diameter of armature, and valve body is provided with passage, and valve port links to each other with passage.
Micro leak-free low voltage electromagnetic valve of the present invention, valve channel are positioned at the valve port end portion and preferably are provided with the groove that matches with the moving armature lower end.
The present invention is provided with passage in the electromagnetic valve body bottom, is used for placing the medium pipeline flexible pipe, thereby liquid or gas stream do not need to cut off pipeline when crossing solenoid valve, has stopped the problem that medium is revealed.Because the present invention is simple in structure, removed the interface of traditional electrical magnet valve connecting pipeline, make the volume of valve body dwindle greatly.The present invention is particularly useful for the reliability height, and zero pollution, little application, space are with a wide range of applications.

Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Solenoid valve overall structure of the present invention as shown in Figure 1.Valve body 7 adopts aluminum alloy or titanium alloy material to make, and valve body 7 has valve port 12, and valve port 12 can hold moving armature 6 and spring 10.The below of valve body 7 is provided with passage 8, passage 8 is used for placing the flexible pipe 13 of transmitting medium, the size of passage 8 should match with flexible pipe 13, link to each other with passage 8 with the lower end of valve port 12, also be provided with groove (not drawing among the figure) on passage 8 walls under the valve port 12, when moving armature 6 is compacted, just in time fall into groove.Be installed with coil rack 3 above the valve gap 2, coil 5 is installed on the coil rack 3, coil rack 3 hollows, and moving armature 6 is placed in the coil rack 3.For prevent that moving armature 6 from coming off, and also is installed with intermediate overcoat 1 by locking nut 2 on valve gap 2 when solenoid valve is inverted.Valve port 12 upper fixed are equipped with compress gasket 9, be positioned at valve port 12 tops of valve body 7, valve port 12 is built-in with an end and is fixed on spring 10 on the compress gasket 9, and the internal diameter of spring 10 is greater than the external diameter of moving armature 6, and moving armature 6 passes from the opening on the compress gasket 9.Also be provided with the outlet terminal 11 that links to each other with coil 5 on the valve body 7.Valve body structure as shown in Figure 2,14 among the figure installs pressing plate for flexible pipe, is used for fixing flexible pipe 13.
When solenoid valve uses, earlier the flexible pipe 13 of transmitting medium is inserted the passage 8 of electromagnetic valve body 7, the compress gasket 9 that will be fixed with spring 10 again is fixed on the valve body 7 by screw, and the intermediate overcoat 1 on moving armature 6, valve gap 2 and the valve gap 2 is installed afterwards.When coil 5 access failure power supplys, the effect of pressured tight pad 9 and spring 10, flexible pipe 13 is tightly pushed down in the lower end of moving armature 6, and make it fall into groove on passage 8 walls, thereby cut off pipeline fully, when needs were connected pipeline, coil 5 was connected power supplys, and moving armature 6 overcomes on the pressure of spring 10 exercises the pipeline conducting.
