Embodiment
The utility model is described in detail with reference to specific embodiments and the drawings.
As shown in figure 1, provide a kind of flow control electromagnetic valve for the utility model, including first without friction magnetic valve 1, hold
Chamber matrix 2, second is without friction magnetic valve 3, pressure sensor 4.First leads to without friction magnetic valve 1 and second without friction magnetic valve 3
Cross square flange and be symmetrically arranged on the both sides of cavity volume matrix 2, it is necessary to when working, be first powered to first without friction magnetic valve 1, valve element 9
Overcome medium power and frictional force to move, open medium inlet, upstream medium is to be pressurized in cavity volume matrix 2；First without friction afterwards
Magnetic valve 1 is powered off, and medium inlet is closed, and second is powered without friction magnetic valve 3, and media outlet is opened, the medium supplement in cavity volume
Give lower pressure downstream component；Second is powered off without friction magnetic valve 3 after pressure balance, and media outlet is closed, and completes a flow supply,
Downstream components pressure, which rises, is more than 1kpa, less than 3kpa, and one time flow supplies round robin ≯ 100ms, by macroscopic time
Interior flow supplies the change of number of times, and the control to different flow can be achieved., can by the change to the volume size of cavity volume matrix 2
To realize the regulation of single quantity delivered.Pressure sensor 4 is installed on above cavity volume matrix by screw thread, real by sealing copper backing
Now seal, pressure sensor 4 is by the collection to the gas pressure data of cavity volume matrix 2, available for remotely judging first without friction
Working condition of the magnetic valve 1 and second without friction magnetic valve 3.
As shown in Fig. 2 i.e. first without friction magnetic valve 1 and second without friction the structural representation of magnetic valve 3, mainly by valve body
5th, coil 6, shell 7, filter 8, valve element 9, planar spring 10, valve seat 11 are constituted, and valve element 9 is by the suspension branch of planar spring 10
Support, it is to avoid skimming wear with valve body；Valve element 9 is cooperatively formed close by the elastic deformation force of planar spring 10 with valve seat 11
Envelope is secondary, it is possible to achieve two way seal function, controls the inflow and outflow of medium.First without friction magnetic valve 1 and second without friction
The primary structure of magnetic valve 3 is completely the same.
As shown in figure 3, being the structural representation of planar spring, the structure uses special helix structure, with traditional S
Type planar spring structure is compared, and can meet long life requirement, and structural stress is small, uniformly without mutation, can guarantee that sealing is required again
Rigidity, realize two way seal requirement.Drawn according to the design of finite element structure optimization Simulation and lot of experiments, the structure reed branch
When supportting helical length for 0.6 π (D-d)~0.8 π (D-d), its combination property is optimal.
