Specific embodiment
Generally according to the present invention, the optimal feasible embodiment, and cooperate figureAfter detailed description, increase to this hair
Bright understanding, and the schema in the present invention illustrates use for understanding as embodiment with a kind of three mouthfuls of two solenoid valves, also can
For having in the electromagnetic valve structure of pressure difference influence, it is not restricted to this.
The present invention provides a kind of solenoid valve valve configurations of electronically controlled proportional valve, such as schemesIt is shown, there is a solenoid valve 10,
It is internal configured with a fixed iron core 11, a movable iron spring 12 and a movable core 13, which is set to should
Among fixed iron core 11 and the movable core 13, it can be powered by the spiral winding 14 being equally set in the solenoid valve 10
After excitation, make the movable core 13 with the fixed iron core 11 coaxially to push；
One guide valve 20 connects the solenoid valve 10, and the inside of the guide valve 20 has a valve port 21 and is arranged with
One air guide valve rubber 24 of one elastic parts 23, and the air guide valve rubber 24 is respectively arranged with a first side in arranged on left and right sides
241 and a second side 242, and a guide valve rubber base 25 is configured between the air guide valve rubber 24 and the movable core 13,
The air guide valve rubber 24 can be carried out switching fluid D flow path 30 by reciprocal axial motion；
The guide valve 20 also has a supply mouth A, a delivery outlet B and an outlet C, and the guide valve 20 is another
End is equipped with a guide valve rear cover 26, first side of the guide valve rear cover 26 with unification 23 contact of elastic parts, one air guide valve rubber 24
Face 241, and the second side 242 of the air guide valve rubber 24 is then combined with a guide valve rubber base 25, so as in the guide valve 20
Middle section form a valve port 21, and 25 other end of guide valve rubber base then connects movable core 13 above-mentioned, makes valve port
21 are able to that fluid D is allowed to be switched into out in flow path 30, also form multiple rooms whereby, and wherein room can divide into one first room
31, one second room 32 and a third room 33, cooperate aforementioned structure in valve port 21 leading portion to supply mouth A with
Delivery outlet B is the first room 31；And 21 back segment of valve port to the 10 inside leading portion of solenoid valve is the second room 32；And the electromagnetism
It is then third room 33 at 13 setting of movable core in 10 middle section of valve；
The solenoid valve 10 is as described below by electrically driven (operated) continuous action with guide valve 20, and the first step is that the solenoid valve 10 exists
When being not powered on excitation, after fluid D is inputted by supply mouth A, cooperate the air guide valve rubber 24 barrier in first room 31,
Valve port 21 at this time then for the state closed forward and first room 31 has the pressure of fluid D input, and the second room 32
It is then pressure-less state with third room 33；Its second step is the movable core 13 when the solenoid valve 10 is by energization excitation
With the fixed iron core 11 coaxially to push, it will drive the valve port 21 to open backward, and the fluid D in the first room 31 originally
The second room 32 can be passed through with the flow path 30 to the third room 33, segment fluid flow D at this time can flow to phase through delivery outlet B
The equipment of connection, and first room 31, the second room 32 and third room 33 are then pressure balanced state；And work as third
When step, when which is again off power supply stopping excitation, which is pushed ahead by the movable core 13, this is led
Air valve rubber base 25 then can the contact air guide valve rubber 24, and then close the valve port 21, script is inputted by supply mouth A
Fluid D can then be restricted in first room 31, and fluid D in the second room 32 and third room 33 originally, this
Shi Zehui is discharged with outlet C, and the pressure that first room 33 is then still inputted with fluid 31, and 32 He of the second room
Third room 33 is then pressure balance.
It is please referred to again such as figureIt is shown, at said valve mouth 21, it is further provided with a valve mouth 22, after energization excitation,
The air guide valve rubber 24 by fluid D push away toward valve port 21 be in contact when, because 22 periphery of valve mouth be equipped with the conical surface or concave design,
Fluid D can be made more unobstructed through flow path 30 to valve port 21 and the guiding of the second side 242 of the air guide valve rubber 24, make the electricity
Pressure balance more immediate stability between magnet valve 10 and guide valve 20；
The sectional area of the valve port 21 can make the guide valve when 242 half of second side less than the air guide valve rubber 24
Rubber 24 and the pressure difference of the valve port 21 displacement are reduced, so as to promoting the rate of movable 12 axial displacement of iron spring；In detail and
Speech, that is, in the state of being not powered on excitation, because of the first side 241 of air guide valve rubber 24 and the pressure difference of second side 242
Reduce, which pushes the movable core 12 to reset required spring force and also can therefore reduce, and is improved reset whereby
Rate.
And the conical surface or concave design of the valve mouth 22, when the angle E of the second side 242 with the air guide valve rubber 24 is big
When 45 degree, it can ensure that fluid D is being stopped by the flow that the first side 241 of air guide valve rubber 24 is circulated to second side 242
After excitation, the flow of 242 fluid D of second side is able to cooperate the spring force of the movable iron spring 12, it is allowed to reset the rate carried out
It can be more quick compared with well known structures.
In conclusion the solenoid valve valve configurations of electronically controlled proportional valve provided by the invention, by valve mouth 22 with the conical surface or
The sectional area of the design of concave surface or valve port 21 is less than the half, again or the valve mouth 22 and the second side of second side 242
The angle E in face 242 is greater than 45 degree, and fluid D can improve whereby in air guide in energization excitation or in the state of be not powered on excitation
Generated pressure difference on valve rubber 24, and then promote the speed of the actuation frequency response of solenoid valve 10.
