Detailed Description
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model provides a gas circuit control device, including air supply pump 8, solenoid valve 1, two 2 solenoid valves, one-way choke valve 3, two 4 one-way choke valves, cylinder 5, cylinder two 6, air supply pump 8 gives vent to anger the end and passes through air cleaner 9 and two 2 intercommunications of solenoid valve, two 2 solenoid valves and two 4 one-way choke valves intercommunication, two 4 one-way choke valves give vent to anger the end and cylinder 5, two 6 the inlet end is connected, the end of giving vent to anger of cylinder 5, two 6 communicates with one-way choke valve 3, one 3 give vent to anger the end and is connected with one 1 solenoid valve through two 4 solenoid valves, one 1 solenoid valve is connected with silencer 7. The first electromagnetic valve 1 and the second electromagnetic valve 2 are two-position five-way reversing electromagnetic valves.
The gas path circulation control can be better realized. Travel switches SQ1, SQ2, SQ3 and SQ4 are arranged on the first air cylinder 5 and the second air cylinder 6. The operation stroke of the air cylinder can be better controlled. A manual valve 10 is arranged between the air source pump 8 and the air filter 9. The manual closing can be realized under the conditions of power failure and the like.
The air filter 9 is connected with a bidirectional direct-acting pressure reducing valve 11 with a pressure gauge. Is favorable for better regulating the gas pressure. And a pressure relay 12 is arranged between the air filter 9 and the second electromagnetic valve 2. The on-off of the electric protection gas circuit can be better carried out.
As shown in fig. 1, the air flow passes through the pneumatic pretreatment element to the electromagnetic valve two 2, at this time, the electromagnetic valve head SY2 of the electromagnetic valve two 2 is electrified to work, so that the right valve position works, the air flow passes through the port B and then passes through the one-way throttle valve two 4 of the control element to the right end of the air cylinder 5 (the switch SQ1 is electrified to work) or the left end of the air cylinder 6 (the switch SQ 1' is electrified to work), the air flow in the reverse cavity of the air cylinder passes through the one-way throttle valve one 3 to the port a of the electromagnetic valve two 2 to the port a of the electromagnetic valve one 1 to complete the exhaust of the muffler, and at this; then, as shown in fig. 2, a door closing command is given, the system sends out a signal, the electromagnetic head SY1 of the electromagnetic valve two 2 is electrically operated, the left valve position works, so that the gas passes through the A port of the electromagnetic valve II 2 to the one-way throttle valve I3 of the control element and then to the left end of the cylinder 5 (the SQ1 is switched on and works) and the right end of the cylinder 6 (the SQ 1' is switched on and works), the door starts to close, when the end of the stroke is reached, the SQ3 and SQ 3' switches are triggered to give a signal to the system, so that the system sends a command to control the electromagnetic head SY3 of the electromagnetic valve I1 to be electrically operated, the airflow in the reverse direction of the cylinder is exhausted through the left valve position of the electromagnetic valve I1 and the exhaust throttling silencer 7, at the moment, the airflow regulation of the silencer 7 element is much smaller than the airflow of the control element one-way throttle valve I3, and maintains the state as shown in fig. 3, thereby playing the role of deceleration and greatly reducing the impact force when the door is closed; otherwise, the same principle is applied when the door is opened.
The embodiment ensures the requirement of quick opening and closing the door and reduces the impact when the door is opened and closed. The requirement of quick door opening can be met by combining the standard air cylinder and the standard valve, the problems of long delivery cycle and high price of the quick air cylinder are solved, and the stability and quick response of the control air circuit are improved.
