Description
Technical field
The utility model relates to a kind of multiposition valve structure, belongs to the fluid applications such as chromatogram, hydraulic pressure, air pressure.
Background technique
Multiposition valve is that laboratory carries out analyzing or industrial field carries out production common equipment, generally primarily of stator, rotor, several large parts composition of motor.Stator is provided with center flow channels and the branch flow passage of circle distribution centered by center flow channels; Rotor also there is runner; Motor shaft is connected with rotor, by drive motor thus rotor driven rotate, epitrochanterian runner corresponding rotation angle, thus be communicated with stator center runner to different branch flow passages, to realize the switching of runner.
In prior art, rotor and stator contact area cause very greatly frictional force also large, just need very large moment to overcome this frictional force during rotation; And area of contact greatly also means that wear area is also large.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of multiposition valve.
The technological scheme that the utility model adopts: a kind of multiposition valve, stator is provided with the branch flow passage of center flow channels, multiple circle distribution centered by center flow channels, rotor is provided with runner, rotor is connected with motor shaft, motor often turns several angle, stator center runner is connected on different stator branch flow passages through rotor flow tract, it is characterized in that, a transition plate is had between stator and rotor, this transition plate is provided with the intermediate throughholes corresponding with stator center runner, and multiple circle distribution centered by this intermediate throughholes and the perimeter throughbores corresponding with stator branch flow passage; Motor often turns several angle, and stator center runner is connected to different transition plate perimeter throughbores through transition plate intermediate throughholes, rotor flow tract, then through the runner between transition plate and stator, be finally connected to stator branch flow passage.
Compared with prior art, the beneficial effects of the utility model are: effectively reduce required motor torque.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, 2, during operation, motor (04) rotor driven (03) rotates, and stator (01) directly contacts with rotor (03); Before Fig. 1 runner switches, stator center runner (06) is connected to stator branch flow passage (05) through rotor flow tract (02); After Fig. 2 runner switches, stator center runner (06) is connected to stator branch flow passage (07) through rotor flow tract (02); Visible, rotor and stator contact area are very large, and corresponding moment of rotation requires just high.
As shown in Figure 3,4, a transition plate (2) is had between stator (1) and rotor (3), this transition plate is provided with the intermediate throughholes (6) corresponding with stator center runner (10), and multiple circle distribution centered by this intermediate throughholes and the perimeter throughbores corresponding with stator branch flow passage (7,11); Motor (4) rotor driven (3) rotates, and carries out runner switching; Before Fig. 3 runner switches, stator center runner (10) is connected to transition plate perimeter throughbores (7) through transition plate intermediate throughholes (6), rotor flow tract (5), then through the runner (8) between transition plate and stator, be finally connected to stator branch flow passage (9); After Fig. 4 runner switches, stator center runner (10) is connected to transition plate perimeter throughbores (11) through transition plate intermediate throughholes (6), rotor flow tract (5), then through the runner (12) between transition plate and stator, be finally connected to stator branch flow passage (13).Visible, owing to introducing transition plate (2), rotor (3) is very little with transition plate (2) area of contact, greatly reduces the requirement to moment of rotation.
As shown in Figure 5,6, a diaphragm seal (14) is had between stator (1) and transition plate (2), sealing sheet is provided with the intermediate throughholes (16) corresponding with stator center runner (10), and multiple circle distribution centered by this intermediate throughholes and the diaphragm seal branch flow passage corresponding with stator branch flow passage (15,17); Motor (4) rotor driven (3) rotates, and carries out runner switching; Before Fig. 5 runner switches, stator center runner (10) is connected to transition plate perimeter throughbores (7) through diaphragm seal intermediate throughholes (16), transition plate intermediate throughholes (6), rotor flow tract (5), then through the runner (8) between transition plate and diaphragm seal, diaphragm seal branch flow passage (15), be finally connected to stator branch flow passage (9); After Fig. 6 runner switches, stator center runner (10) is connected to transition plate perimeter throughbores (11) through diaphragm seal intermediate throughholes (16), transition plate intermediate throughholes (6), rotor flow tract (5), then through the runner (12) between transition plate and diaphragm seal, diaphragm seal branch flow passage (17), be finally connected to stator branch flow passage (13).Visible, owing to introducing transition plate (2), rotor (3) is very little with transition plate (2) area of contact, greatly reduces the requirement to moment of rotation.
