Further, in some embodiments provided by the present invention, referring to fig. 2, a first pressing plate 223 is disposed between the first pilot head 22 and the pilot valve body 2.

That is, in this embodiment, the first pilot head 22 adopts the structure of an electromagnetic pilot valve, and the main working principle and other structures thereof are well known to those skilled in the art, and the present invention will not be described herein again.

Following regard as first guide head 22 with adopting the electromagnetism pilot valve to use the angle valve as the evacuation valve as an example, simply introduce the utility model provides a working process of angle valve:

in a state where the first coil 221 is not energized, the first pilot port 24 is closed by the first plunger 222, and the supply air entering from the air inlet 20 of the pilot valve body 2 cannot reach the third chamber 26, so that the pilot valve piston 28 is pushed by the elastic force of the elastic member 3, the seal head 29 is pressed against the communication port 15, and the communication port 15 is closed, and at this time, the first operation passage 10 and the second operation passage 12 are disconnected. When the first coil 221 is energized, the first movable iron core 222 is attracted by the first stationary iron core, and then the first pilot port 24 is opened, after the air supply entering from the air inlet 20 of the pilot valve body 2 enters the third cavity 26, the air pressure in the third cavity 26 gradually increases, and the pilot valve piston 28 is pushed to move after overcoming the elastic force of the elastic member 3, so that the sealing head 29 is separated from the communication port 15, and then the communication port 15 is opened, and at this time, the first working channel 10 and the second working channel 12 are communicated.

Because the second working channel 12 is externally connected with a vacuum pumping device (e.g., a vacuum pump), air in the first working channel 10 is pumped away to form a vacuum working environment, and further, a workpiece, such as a mobile phone, can be adsorbed through the first working channel 10. Then, after the first coil 221 is powered off, the sealing head 29 is pressed on the communication port 15 again due to the elastic force of the elastic member 3, so as to close the communication port 15, and further disconnect the first working channel 10 and the second working channel 12, at this time, the first working channel 10 is always kept in a vacuum state, and further, the workpiece can be stably adsorbed, and an external vacuum-pumping device does not need to be kept in a working state all the time. After the second pilot port 25 is opened by the second pilot head 23, since the first working channel 10 is communicated with the air inlet 20 through the second pilot port 25, the air (such as air) supplied through the air inlet 20 of the pilot valve body 2 enters the first working channel 10, so as to break the vacuum environment in the first working channel 10, and further, the adsorbed workpiece can be detached.

Further, in some embodiments provided by the present invention, referring to fig. 2, a second pressing plate 233 is disposed between the second pilot head 23 and the pilot valve body 2. That is, in this embodiment, the second pilot head 23 also adopts the structure of the electromagnetic pilot valve, and the main working principle and other structures thereof are well known to those skilled in the art, and the present invention will not be described herein again.

Further, referring to fig. 2-3, in some embodiments of the present invention, a fourth cavity (not shown) and a manual button 5 for sealing the fourth cavity are further disposed on the pilot valve body 2, and the fourth cavity 4 is communicated with the third cavity 26. That is, in this embodiment, the manual button 5 can be controlled to open the third chamber 26 to the atmosphere to exhaust the high-pressure gas in the third chamber 26, and the sealing head 29 closes the communication port 15 by the elastic force of the elastic member 3 to disconnect the first working channel 10 and the second working channel 12.
