The technical solution of the utility model is as follows:
Comprise sucker, orifice plate seat, drive unit and valve gap; The surface of contact of sucker and orifice plate seat plane is each other sealing strip, and sealing strip separates hyperbaric chamber and low-pressure cavity; The inner chamber of valve gap and orifice plate seat composition is hyperbaric chamber, and sucker is arranged in the hyperbaric chamber of valve gap and orifice plate seat composition; Valve gap is arranged through hole A, through hole A is communicated with high-voltage power supply; Drive unit is made up of worm screw, worm gear pair, and turbine is arranged on sucker, and worm screw is arranged on orifice plate seat; Sucker is arranged through hole B, through hole F and blind hole D, blind hole F1, blind hole F2, through hole B, through hole F are communicated with hyperbaric chamber, blind hole D, blind hole F1, blind hole F2 are through cross-drilled hole E1, cross-drilled hole E2 intercommunication, and low-pressure cavity is communicated with outlet, and blind hole D is communicated with low-pressure cavity; Orifice plate seat is arranged through hole C, through hole C1, through hole C2 and through hole G, through hole G is communicated with low-pressure cavity and outlet.
The utility model has the advantages of as follows:
1, there is multidigit, lead to more, into and out of (row) double-action synchronism switching function.
2, operating cost is low, and sealing is reliable, and commutation is steady, friction.
3, high pressure, big orifice demand can be met, be applicable to the particular surroundingss such as high temperature resistant, corrosion-resistant.
The utility model principle is as follows:
Produce pressure with the pressure reduction of sucker both sides, make sucker suction on orifice plate seat.The surface of contact plane each other of sucker and orifice plate seat, the seamless contact of surface of contact is utilized to reach sealing effect, drive unit drives sucker to do stone turning on orifice plate seat and moves, with the connected state of each hole and hyperbaric chamber and low-pressure cavity on this alternate type synchronous change orifice plate seat, realize multidigit, lead to more, into and out of (row) double-action synchronous communicating function.

Embodiment
Below, with reference to accompanying drawing, in conjunction with specific embodiments, the utility model is described in more detail.
embodiment 1:
As shown in figure (), (two), sucker 1 is provided with through hole B, through hole F, blind hole D, blind hole F1, blind hole F2, through hole B, through hole F are communicated with, blind hole F1, blind hole F2 are communicated with blind hole D by transverse holes or groove E1, transverse holes or groove E2, blind hole D all the time on orifice plate seat 2 through hole G with go out (row) mouth and be communicated with, formed low-pressure cavity 2., through hole B all the time on valve gap 4 through hole A be communicated with high-voltage power supply; Orifice plate seat 2 is provided with through hole C, through hole C1, through hole C2 and through hole G, outside through hole G all the time with go out (row) mouth and be communicated with, through hole G opposite side is communicated with blind hole D on sucker 1 all the time; Valve gap 4 is arranged through hole A, through hole A is high pressure entry, and valve gap 4 inner chamber via through holes A is communicated with high-voltage power supply all the time, forms hyperbaric chamber 1.; Sucker 1 forms closed annular seal band with the surface of contact S of orifice plate seat 2; Drive unit 3 is made up of worm screw, worm gear pair, and turbine is arranged on the suction cup 1, and worm screw is arranged on orifice plate seat 2.
