Description
Technical field
The utility model relates to electromechanical numerical control part field, in particular to a kind of normally closed type high-speed switch valve.
Background technique
It has been key work to overall operation in electromechanical numerical control sciemtifec and technical sphere more particularly to high-speed switch valve field
?.High-speed switch valve is to realize numerically controlled key element, and the on-off of electromagnet is controlled according to a series of electric impulse signals
Electricity promotes the forward and reverse high-speed motion of spool, to realize the on-off of valve port liquid stream.Due to the characteristic that high-speed switch valve is excellent,
It is concerned in development process, has also attracted large quantities of scholars both domestic and external it to be unfolded corresponding theoretical research, and achieve one
Fixed achievement plays positive effect to the development for instructing high-speed switch valve of new generation.More make us it is worth noting that because of height
The response characteristic of fast switch valve, scholars apply it to anti-lock braking system in automobiles (ABS).
Utility model content
The purpose of this utility model is that defect according to prior art, provides a kind of normally closed type high-speed switch valve, it is described
What the technical solution of normally closed type high-speed switch valve was realized in：
A kind of normally closed type high-speed switch valve, it is characterised in that：Including oil outlet, valve seat, valve body, oil inlet, spool, dynamic iron
Core, coil, spring, static iron core and magnetic yoke；The normally closed type high-speed switch valve swings to the "convex" shaped of placement in one；The valve
Seat, spool, dynamic iron core, spring and static iron core are from left to right sequentially connected；The spring is reset spring, most right with dynamic iron core
End connection；The oil inlet is the osculum opened in the middle part of valve body；The oil outlet is the osculum opened in the middle part of valve seat；
The magnetic yoke surrounds the surrounding of upper and lower two coils；The valve seat is connect with spool left end；The dynamic iron core center has one
Opening, spool are fixed on wherein；The static iron core surrounds spring；The valve body up and down hold valve seat, dynamic iron core and
Spool.
Further, the spool is cone valve.
Further, the current value for being input to coil is best between 0.4~0.8A.
Working principle：The normally closed type high-speed switch valve moves spool by the effect of electromagnetic force and reset spring reset force
The open and close of dynamic control valve.When electromagnet coil no power, under the action of reset spring, dynamic iron core and spool are in
Left end, the conical surface and the valve seat of spool are combined closely, and oil inlet and outlet is obstructed, and valve is in close state；After coil is powered, iron is moved
Core and spool under electromagnetic force, overcome reset spring active force and frictional force and so that cone valve is lifted off a seat, oil inlet and outlet
Conducting, valve are in the open state.
The normally closed type high-speed switch valve of the utility model, good seal performance is sensitive, and contamination resistance is strong, is not easy to produce
Raw vibration and noise, can be widely applied to electromechanical numerical control field, meets market application requirement.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the test device of the utility model；
Appended drawing reference：1- oil outlet, 2- valve seat, 3- valve body, 4- oil inlet, 5- spool, 6- dynamic iron core, 7- coil, 8- bullet

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of normally closed type high-speed switch valve, it is characterised in that：Including oil outlet 1, valve seat 2, valve body 3, into
Hydraulic fluid port 4, spool 5, dynamic iron core 6, coil 7, spring 8, static iron core 9 and magnetic yoke 10；The normally closed type high-speed switch valve falls in one
To the "convex" shaped of placement；The valve seat 2, spool 5, dynamic iron core 6, spring 8 and static iron core 9 are from left to right sequentially connected；It is described
Spring 8 is reset spring, is coupled with the right end of dynamic iron core 6；The oil inlet 4 is the osculum opened in the middle part of valve body 3；Institute
Stating oil outlet 1 is the osculum opened in the middle part of valve seat 2；The magnetic yoke 10 surrounds the surrounding of upper and lower two coils 7；The valve
Seat 2 is connect with 5 left end of spool；There is an opening at 6 center of dynamic iron core, and spool 5 is fixed on wherein；The static iron core 9 wraps
Round spring；About 3 valve body holds valve seat 2, dynamic iron core 6 and spool 5.
When it is implemented, the spool 5 is cone valve.
When it is implemented, the current value for being input to coil 7 is best between 0.4~0.8A.
Working principle：The normally closed type high-speed switch valve makes spool 5 by the effect of electromagnetic force and reset spring reset force
The open and close of Mobile control valve.When 7 no power of electromagnet coil, under the action of reset spring 8, dynamic iron core 6 and valve
Core 4 is in left end, and the conical surface and the valve seat 2 of spool 4 are combined closely, and oil inlet and outlet is obstructed, and valve is in close state；When coil 7
After energization, dynamic iron core 6 and spool 4 under electromagnetic force, overcome reset spring 8 active force and frictional force and leave cone valve
Valve seat 2, oil inlet and outlet conducting, valve are in the open state.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
