Abstract
The large flow rotary gas valve includes a valve body with an atmosphere port, a sucking port and a jointing port; a valve core capable of rotating inside the valve body, and a motor connected to the valve core for driving the valve core. The motor is preferably stepped motor. The valve core has outer surface fitting hermetically with the inner surface of the valve body and has one or several through holes communicated optionally to the jointing port or atmosphere port via rotation. The present invention has simple structure and convenient control, realizes high speed control of large flow of gas via rotation, and is used in post treatment.
Description
Technical field
The present invention relates to a kind of absorption mail air valve, particularly a kind of absorption mail is with big flow gas control valve.
Background technique
In the accommodation distribution process, need use absorption mail air valve, by to the suction of mail with put and carry out accommodation distribution.Of the prior art being somebody's turn to do adsorbed mail with air valve as shown in Figure 1, and it mainly is made up of last electromagnet 1, moving plate 2, suction inlet 3, lower electromagnet 4, adapter 5, following valve body 6, upper valve body 7.Wherein take over 5 (not shown) that link to each other with vacuum pump.Its working principle is: after going up electromagnet 1 energising, adhesive moving plate 2, the intakeport of suction inlet 3 by moving plate 2 belows by valve body 6 down, take over 5 and communicate with vacuum pump, produce negative pressure, the intakeport of suction inlet 3 adsorbs mail.After lower electromagnet 4 energisings, adhesive moving plate 2, the intakeport of suction inlet 3 is communicated with atmosphere by upper valve body 7 by moving plate 2 tops, no negative pressure, the intakeport of suction inlet 3 does not adsorb mail, decontrols the mail that has adsorbed.
Said apparatus is owing to be subjected to its structure influence, and flow and the pressure controlled are limited.As improving negative pressure, then the desired the suction-combining force of electromagnet is wanted corresponding increase, otherwise can not open valve or speed of response are slack-off.Yet the increase of the suction-combining force is limited, therefore can not control high negative.As improving the just necessary distance that increases between moving plate and the electromagnet of flow.Can cause the reduction of speed of response after yet distance increases, finally cause air valve not open.
Summary of the invention
The invention provides a kind of large flow rotary air valve, the high speed control of required big flow gas when solving the negative pressure separation.
For achieving the above object, the present invention adopts following technological scheme,
A kind of large flow rotary air valve comprises a valve body, and described valve body is provided with atmospheric air port, suction inlet and interface, also comprise can be in valve body in relative rotation spool with link to each other with described spool and drive the motor of valve core rotation, the preferred stepper motor of described motor.The outer surface of described spool cooperates with the internal surface hermetic seal of valve body, and described spool is provided with one or more by rotating the through hole that selection communicates with interface or atmospheric air port.
As a kind of improvement of the present invention, described through hole is periodic arrangement on the circumference perpendicular to valve core axis.
One improve as of the present invention again, also comprise coupling, described motor links to each other with spool by coupling.Described coupling is provided with grating, and is provided with light emitting diode and sensitive chip in the both sides of described grating, and hole on the described grating or slit are with corresponding perpendicular to the through hole on valve core axis's circumference.
The present invention is simple in structure, and control is convenient, and the cut-out and the conducting of the rotation control air-flow by spool have realized the high speed control to big flow gas.Thereby accelerate the processing rate of mail.
Description of drawings
Further specify the present invention below in conjunction with drawings and Examples.

Embodiment
As shown in Figure 1, a kind of large flow rotary air valve is applied to mail treatment.It comprises a valve body 14, coupling 17, can be in valve body 14 in relative rotation spool 12, drive stepper motor 16, the coupling 17 that spool 12 rotates, light emitting diode (not shown) and the sensitive chip (not shown) that is arranged at the grating 15 on the coupling 17 and is arranged at described grating 15 both sides.Described valve body 14 is provided with atmospheric air port 20, suction inlet 11 and interface 13, interface 13 (not shown) that communicates with vacuum pump.Described motor links to each other with spool 12 by coupling 17.The outer surface of described spool 12 cooperates with the internal surface hermetic seal of valve body 14, and described spool 12 is provided with one or more selection communicates with atmospheric air port 20 or interface 13 when spool 12 rotates through hole 18 and through holes 19.Described through hole 18 and described through hole 19 are periodic arrangement on the circumference perpendicular to spool 12 axis.Hole on the described grating 15 or slit are with corresponding perpendicular to through hole 18 and through hole 19 on the spool 12 axis circumference.
After spool turned over several angle, 5 rounds of its top were corresponding mutually, and 1 row of below is just in time interlaced, and suction inlet 11 communicates with vacuum pump by the interface 13 on spool 12, the valve body 14, suction inlet 11 places generation negative pressure.
The angle of spool 12 rotation positioning is by stepper motor 6 and grating 15 and light emitting diode, sensitive chip control.
In the foregoing description, the pressure size of controlled gas can not have influence on the required power of spool 12 rotations, and the size that is to say controlled gas pressure is to the not influence of this device.It is just passable as long as increase the gross area of institute's perforate on valve body 14 and the spool 12 to increase flow if desired, as required can be with valve body 14 and spool 12 lengthenings.Can also adjust the response frequency of valve by the spacing that changes Kong Yukong.
This structure has realized the high speed control of big flow gas by the cut-out and the conducting of the Relative motion control air-flow of bicylindrical body.It is simple in structure, and control is convenient.
