Technical field
The invention belongs to electromechanical engineering field more particularly to a kind of flow control electromagnetic valves.
Background technique
Traditional flow control valve is to adjust rate-of flow by changing choke area, and driving mechanism is typically chosen
The features such as torque-motor, motor etc., such flow control valve have flow degree of regulation high, and the linearity is good, but its structure all compared with
For complexity, difficulty height is controlled, it is less economical.For some need, macroscopically flow is adjustable, stablizes, and product structure is simple, controls
Simply, reliable operation long service life, the application field of good economy performance, traditional flow control valve are not appropriate for.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of flow control electromagnetic valve is provided, to solve in the prior art
Structure is complicated, poor reliability, is not suitable for the defect of the adjustable operating condition of macroscopic view.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of flow control electromagnetic valve is characterized in that including cavity matrix, the first solenoid valve and the second electromagnetism
Valve, first solenoid valve and second solenoid valve are separately positioned on cavity matrix two sides, and medium enters appearance by the first solenoid valve
Chamber matrix, then flowed out from second solenoid valve.
Further, pressure sensor is provided on the cavity matrix.
Further, first solenoid valve and/or second solenoid valve are including valve body, to be wrapped in without friction solenoid valve
Coil, spool, reed and valve seat on valve body, the reed provide suspension support to spool, are provided with and cavity base on valve seat
The aperture that body communicates.
Further, the reed is annular, is provided with a plurality of spirality groove on reed.
Further, the spirality groove length is 0.6 π (D-d)~0.8 π (D-d), wherein D is outside annular reed
Diameter, d are annular reed internal diameter.
The beneficial effects of the present invention are: due to carrying out flow control using without friction solenoid valve combination, it is entirely avoided pass
The skimming wear united between direct driving type electromagnetic valve core and guide surface, greatly improves the service life of solenoid valve, with conventional flow
Control valve is compared, and product structure is simple, control is simple, stability of flow, reliable operation, long service life, good economy performance.

Specific embodiment
The present invention is described in detail with attached drawing combined with specific embodiments below.
As shown in Figure 1, provide a kind of flow control electromagnetic valve for the present invention, including first without friction solenoid valve 1, cavity base
Body 2, second is without friction solenoid valve 3, pressure sensor 4.First without friction solenoid valve 1 and second without friction 3 side of passing through of solenoid valve
Shape flange is symmetrically arranged on 2 two sides of cavity matrix, when needing work, is first powered to first without friction solenoid valve 1, spool 9 overcomes
Medium power and frictional force movement, open medium inlet, and upstream medium is pressurization in cavity matrix 2；First without friction electromagnetism later
Valve 1 powers off, and medium inlet is closed, and second is powered without friction solenoid valve 3, and media outlet is opened, and the medium in cavity is supplemented to low
Press downstream components；Second powers off without friction solenoid valve 3 after pressure balance, and media outlet is closed, and completes a flow supply, downstream
Component pressure, which rises, is greater than 1kpa, is less than 3kpa, and flow supplies round robin ≯ 100ms, by flowing in macroscopic time
Amount supply number changes the control, it can be achieved that different flow.Pass through the change to 2 volume size of cavity matrix, Ke Yishi
The adjusting of existing single supply amount.Pressure sensor 4 is installed on above cavity matrix by screw thread, is realized by sealing copper backing close
Envelope, pressure sensor 4 by the acquisition to 2 gas pressure data of cavity matrix, can be used for remotely judge first without rub electromagnetism
Valve 1 and the second working condition without friction solenoid valve 3.
As shown in Fig. 2, i.e. first without friction solenoid valve 1 and second without friction 3 structural schematic diagram of solenoid valve, mainly by valve body
5, coil 6, shell 7, filter 8, spool 9, planar spring 10, valve seat 11 form, and spool 9 is by the suspension branch of planar spring 10
Support, avoids the skimming wear with valve body；Elastic deformation force of the spool 9 by planar spring 10 cooperatively forms close with valve seat 11
Envelope is secondary, and two way seal function may be implemented, control the inflow and outflow of medium.First without friction solenoid valve 1 and second without friction
3 primary structure of solenoid valve is completely the same.
As shown in figure 3, being the structural schematic diagram of planar spring, which uses special helix structure, with traditional S
Type planar spring structure is compared, and long life requirement is both able to satisfy, and structural stress is small, uniformly without mutation, and can guarantee needed for sealing
Rigidity, realize two way seal requirement.It is obtained according to the design of finite element structure optimization Simulation and a large number of experiments, the structure reed branch
When support helical length is 0.6 π (D-d)~0.8 π (D-d), comprehensive performance is optimal.
