The invention discloses a pneumatic delayed reversing module. The pneumatic delayed reversing module comprises a valve body; two delayed reversing mechanisms are integrated on the valve body; each delayed reversing mechanism comprises a two-position three-way reversing valve, a one-way throttling valve and an energy storage cavity; each two-position three-way reversing valve comprises a reversingvalve cavity and a reversing valve rod; control gas channels matched with the one-way throttling valves are arranged in the valve body; input openings of the one-way throttling valves communicate withthe control gas channels; output openings of the one-way throttling valves communicate with the energy storage cavities; each energy storage cavity communicates with one end of the corresponding reversing valve cavity; a reset spring matched with the corresponding reversing valve rod in an abutting manner is arranged at the other end of each reversing valve cavity; the valve body is further provided with a quick-discharging valve; the quick-discharging valve is arranged in one of the delayed reversing mechanisms; and the quick-discharging valve comprises a quick-discharging opening. When themodule works, the two pneumatic delayed reversing mechanisms can keep independent work and can promote each other in function, so that two actuating elements can be controlled simultaneously to perform sequential graded actions. The module is simple and reasonable in structure and stable and reliable in work performance.
Description
technical field [0001] The invention relates to the technical field of pneumatic reversing components, in particular to a pneumatic time-delay reversing module. Background technique [0002] Delay reversing valve is often used to control the reversing frequency and on-off time ratio of gas. The control methods of the current delay reversing valve are as follows: electromagnetic control, air pressure control, manual control and mechanical control. Among them, the solenoid-controlled delay reversing valve needs to provide an external power supply; the manual control delay reversing valve is too low in automation, it is difficult to accurately control the delay time, and the action speed is slow; the mechanically controlled delay reversing valve structure It is too complicated, and the reliability is not high; the structure of the pneumatic time-delay reversing valve controlled by air pressure is relatively simple, and the reliability is high, so it is widely used. [0003] T...
