The rotary part 15 of circumference rotation that what fixing axle rotated do drives, and the first pressure-producing part 7 and the second pressure-producing part 9 do relative contrary
Direction moves in parallel, and realizes the state switching of port 18.First pressure-producing part 7 and the second pressure-producing part 9 are by turning around fixing axle
The dynamic rotary part 15 doing circumference rotation drives and produces linkage, is rigid contact positive drive between them, and first adds
Splenium part 7 is synchronous with the second pressure-producing part 9 to be moved so that valve system response time is short relative to generation.
Specifically described in following two embodiments.
Example 1
As shown in figure 1, this preferred embodiment is taking a miniature three-way valve as a example, each part of three-way valve is distributed along axis；Three
Port valve has valve body 14, and shell 1 is integrally attached to valve body 14, shell 1 and valve body 14 as main valve body, in shell 1 and valve body 14
It is internally formed airtight space, in this space built with solenoid portion and valve system.
As shown in Fig. 2 valve body 14 is hexahedron structure, the first pressure-producing part 7 and second pressure-producing part 9 of a hollow,
Connected movement producing with main valve body diameter parallel；Rotary part 15 is between the first pressure-producing part 7 and the second pressurization part
Between part 9, with the first pressure-producing part 7 and the second pressure-producing part 9 rigid contact therewith, form valve system with movable core 12.
As shown in figure 1, solenoid portion includes with lower component: be arranged in the blessing device 5 within shell 1；There is employing
Secured core 2 that is cylindrical structural and being installed to blessing device 5 upper surface；Multiturn coil composition solenoid 4 pass through around
It is loaded on secured core 2 outside spool 3；Being arranged in the hole that bobbin 3 is formed of movable core 12 mobility, movable core
5 are arranged with predetermined gap 11 on axis with secured core 2.
Valve seat 17 and valve body 14 are connected by screw fastening, seal and realized by diaphragm 16 between valve seat 17 and valve body 14,
Form cavity 19 between diaphragm 16 and valve seat 17.
As shown in Fig. 2 diaphragm 16 is planar structure, the first diaphragm extension 16a and the second diaphragm is had to expand thereon
Exhibition portion 16b, structure is cylinder boss, and position corresponds to the first plane expansion structure 17a and the extension of the second plane of valve seat 17 respectively
Structure 17b.
As shown in Fig. 2 the first plane expansion structure 17a and the second plane expansion structure 17b of valve seat 17 are that the face of cylinder is little
Boss is relative with the first diaphragm extension 16a of diaphragm 16 thereon and the second diaphragm extension 16b position and organize in pairs
Answer sealing pair.As shown in figure 4, the connecting hole of the first port 18a of valve seat 17, the second port 18b, third connectivity mouth 18c is cylinder
Shape structure, is each communicated with cavity 19.

State.
As shown in figure 1, when unregulated power is applied on solenoid 4, under the thrust of the first pressing spring 6, living
Dynamic iron core 12 is separated with secured core 2, forms predetermined gap 11 between, the first pressure-producing part 7 slide downward, and first
Pressure-producing part 7 forces on diaphragm 16 so as to upper first diaphragm extension 16a is placed in the first plane extension knot of valve seat 17
So that the first port 18a closes on structure 17a, accordingly, the second port 18b and third connectivity mouth 18c are in connected state.This shape
State is three-way valve original state, and original state part sectioned view enlarged drawing is as shown in Figure 2.
When electric current flows through on solenoid 4, solenoid 4 excited target produces suction, makes movable core 12 overcome first
Pressing spring 6 active force, is attracted to secured core 2, drives the first pressure-producing part 7 thereon to move upwards to away from valve seat 17 direction
Dynamic, accordingly, the second pressure-producing part 9 moves down so that rotary part 15 turns clockwise, coupled diaphragm 16 with
Movement, on diaphragm 16, the second diaphragm extension 16b is placed on the second plane expansion structure 17b on valve seat 17, second
Port 18b closes, and the first port 18a and third connectivity mouth 18c is in connected state, thus realizing the sealing of another side runner, complete
Become the switching of port runner.This state enlarged cross-sectional view is as shown in Figure 3.Wherein, the removing of cavity 19 debris, by Fig. 2
And the state of Fig. 3 switches and realizes.
Example 2
As shown in Figure 4 and Figure 5, wherein the first port 18a and third connectivity mouth 18c is arranged on valve seat 17, realize two-way valve and lead to
Mouth State Transferring.Other features are identical with example 1.
Above content be miniature electromagnetic valve with reference to embodiment of the present invention threeway and two-way specifically done detailed further
Illustrate, but it cannot be assumed that present invention is limited only to these illustrate, without departing from the inventive concept of the premise, for belonging to the present invention
For the those of ordinary skill of technical field, some simple replacements can also be made and deduce, all should be considered as belonging to this
The bright scope of patent protection being determined by the claims submitted to.
