Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is illustrated:
As Fig. 1, be depicted as the structure principle chart of two electric control solenoid valves, in gas circuit normal ventilation situation, solenoid valve suction port a and the first electromagnetic valve work mouth b path are high pressure air (the second electromagnetic valve work mouth d, the second solenoid valve relief opening e is exhaust passage), the solenoid valve control end gas-entered passageway f communicated with solenoid valve suction port a has the electromagnetic control end of high pressure air one through to valve gap g simultaneously, the valve plug k that it is controlled when right electromagnetic coil B energising opens, the high pressure air of solenoid valve control end gas-entered passageway f enters the right side of valve core of the electromagnetic valve h through the passage of solenoid valve valve gap g, and the left side of valve core of the electromagnetic valve h is low-pressure cavity, so the high pressure air of the right side of magnet valve spool h just promotes magnet valve spool h and moves to another station (a-d left, b-c leads to for exhaust passage), when right electromagnetic coil A energising, action is contrary.But this valve needs circuit kit now to join does not with it meet the full gas control requirement of pneumatic internal clamp.
As shown in Figure 2,3, valve changes venting control valve structure into as shown in Figure 1, just can meet the full gas control requirement of pneumatic internal clamp; Described two-position five-way double electric control solenoid valve removes electromagnetic coil A, B and transform the venting control valve as; Described venting control valve is two-position five-way valve, comprises valve body 14 and valve gap 8; The hexahedron that there are five through holes in order to place venting control valve spool and to communicate with spool centered by described valve body 14; Described valve gap 8 is fastened on the two ends that valve body 14 is corresponding with spool end; There is gas-entered passageway 10 and the gas storage chamber 12 in order to store high pressure air on described valve gap 8, and between gas-entered passageway 10 and gas storage chamber 12, have to be communicated with gas-entered passageway and gas storage chamber, slow down intake velocity, to spool, commutation provides the solar term passage 11 of enough pressure reduction time; Described gas-entered passageway 10 is connected with the venting control valve control end gas-entered passageway 6 on valve body; There is the air vent 13 in order to be connected with bi-bit bi-pass bleed valve assembly 9 in the central position of described valve gap 8; Place venting control valve spool 7 at described valve body 14 center; There is venting control valve suction port 1, the first venting control valve working hole 2, the second venting control valve working hole 4, the first venting control valve relief opening 3, the second venting control valve relief opening 4, venting control valve control end gas-entered passageway 6 and venting control valve spool 7 at described valve body 14.
The working principle of above-mentioned venting control valve is that the control valve valve core movement commutation that promotes to exit changes station by venting control valve spool two ends moment pressure reduction, high pressure air is by the venting control valve control end gas-entered passageway 6 connected with venting control valve suction port 1, arrive the two ends of venting control valve spool 7 through gas-entered passageway 10, solar term passage 11, the gas storage chamber 12 of valve gap 8, and the formation isopiestic point, the control valve spool 7 of now exitting is in the logical station of 1-2,4-5; When changing into the logical station of 1-4,2-3, needs pass through to handle external left side bi-bit bi-pass bleed valve assembly 9,7 left side high pressure air moments of spool discharge through air vent 13, bi-bit bi-pass bleed valve assembly 9, spool 7 left sides form the low-pressure cavity with respect to right side, left and right sides pressure reduction promotes spool 7 and completes the conversion of station to left movement, and after this left and right sides pressure reduction equates again; If need the conversion of station again, only need to get final product by handling external right side bi-bit bi-pass bleed valve assembly 9, principle is the same; As shown in Figure 3, the control valve valve gap 8 of exitting after described transformation, be to remove top electromagnetic coil part with former solenoid valve valve gap g, and the processing respective channel, gas-entered passageway 10, solar term passage 11, gas storage chamber 12, air vent 13; Gas-entered passageway 10 communicates with the control end gas-entered passageway 6 on valve body; Gas storage chamber 12 is to store a certain amount of high pressure air; At gas storage chamber 12 and gas-entered passageway 10, have a very crucial passage solar term passage 11 that the two is connected, its effect is to slow down intake velocity, and to spool, commutation provides the enough pressure reduction time; Air vent 13 is the passage be connected with the control end.
