Soft start control device for automatic door of air cylinder
The invention belongs to the technical field of pneumatic doors, and particularly relates to an air cylinder automatic door soft start control device which comprises an air inlet end, a tee joint, a shuttle valve, a three-position five-way reversing valve and an automatic door left air cylinder. A first door closing one-way throttle valve and a second door closing one-way throttle valve are connected to the two branch pipes corresponding to the door closing air inlet ends of the automatic door left air cylinder and the automatic door right air cylinder correspondingly. A first door opening one-way throttle valve and a second door opening one-way throttle valve are connected to the two branch pipes corresponding to the door opening air inlet ends of the automatic door left air cylinder and the automatic door right air cylinder correspondingly. The output end of the PLC is electrically connected with a three-position five-way reversing valve and a two-position three-way reversing valve. A high and low air pressure switching mode is mainly adopted, the automatic door is started for the first time, the automatic door is slowly opened and closed through low air pressure, the safe and stable effects are achieved, the first opening and closing action of the automatic door is completed, and back pressure is formed in an air cylinder and a pipeline. And then high-pressure gas is introduced to control the opening and closing of the automatic door, so that the automatic door can be quickly and stably opened and closed.
本发明属于气动门技术领域，具体为一种气缸自动门软启动控制装置，包括：进气端、三通、梭阀、三位五通换向阀、自动门左气缸；所述自动门左气缸、自动门右气缸的关门进气端对应两个支管上分别连接有关门单向节流阀一、关门单向节流阀二，所述自动门左气缸、自动门右气缸的开门进气端对应两个支管上分别连接有开门单向节流阀一、开门单向节流阀二；所述PLC控制器的输出端与三位五通换向阀、两位三通换向阀电性连接。主要采用高低气压切换的方式，在第一次启动自动门动作，用低气压缓慢开合自动门，做到安全稳定的效果，完成自动门第一次开合动作，气缸和管路内形成一个背压。之后通入高压气控制自动门开合，可达到自动门快速且稳定开合。
