Problems solved by technology

[0002] In pneumatic devices, it is usually necessary to change the air passage and then change the flow path of the air flow to meet different pneumatic driving conditions. For large-scale cylinder structures, the usual way of reversing is to set up multiple outlet pipes and install corresponding valves on each outlet channel. Body, the airway reversing is realized by switching different valve bodies, and for the starting structure with multiple inlet channels and outlet channels, this reversing method requires more pipelines and valve bodies, and the whole structure is scattered and complicated, and The control method is more complicated;

Embodiment Construction

[0027]As shown, the present embodiment provides a dual-channel airway commutation device including a commutation assembly and a commutating piston 1, which is slidably mounted in the inner cavity of the commutation assembly, the commutation The assembly is opened with a carrying airway I2, a gas passage II3, a gas passage, and an air passage that communicates with its inner cavity. The air channel I2 and the air passage II3 are respectively used to communicate with the cylinder chamber and the lower chamber. The switching piston has at least two sliding positions and forms two air path states; state one: connect the air passage and the input air channel I2, and connect the air passage II3 and the air passage; state 2: The gas absorbing channel is connected to the air channel II3 and the air passage I2 is in communication with the air passage. CombineFigure 1 to 3 As shown, the commutation assembly has a vertically opened up and down channel, and the upper and lower end cover of the ...

Abstract

The invention discloses a double-channel air channel reversing device. The double-channel air channel reversing device comprises a reversing assembly and a reversing piston, wherein the reversing piston is slidably mounted in an inner cavity of the reversing assembly; an air delivering channel I, an air delivering channel II, an air injection channel and an air outlet channel which communicate with the inner cavity of the reversing assembly are formed in the reversing assembly; the reversing piston has at least two sliding positions and forms the following two air channel states: in the first state, the air injection channel communicates with the air delivering channel I, and the air delivering channel II communicates with the air outlet channel; and in the second state, the air injection channel communicates with the air delivering channel II, and the air delivering channel I communicates with the air outlet channel. According to the double-channel air channel reversing device, reversing of an airflow path can be realized through sliding of the piston, so that the running direction of the piston of an air cylinder is changed; the double-channel air channel reversing device is simple in structure, high in integration degree and easy to control; and the reversing device can realize simultaneous reversing of the air inlet channel and the air outlet channel of the air cylinder, reversing response is quick, and the reversing requirement of quick air inlet and outlet of the large air cylinder on the channels can be met.

Description

Technical field[0001]The present invention relates to the technical field of pneumatic equipment, and more particularly to a dual-channel airway commutation device.Background technique[0002]In the pneumatic device, it is generally necessary to change the flow path of the airway to change the flow path to meet the different pneumatic drive conditions. For large cylinder structures, generally in the reverse manner is to provide a plurality of pastelings and mount the corresponding valve on the respective air passages. Body, the airway commutation is achieved by switching different valve bodies, and for the starting structure of multiple intake passages and airway channels, the interior needed lines and the valve body, the entire structure is complicated, and The control method is more complicated;[0003]Therefore, there is a need for a dual-channel airway commutation device that is highly integrated and convenient for controlling.Inventive content[0004]In view of this, the present inve...
