Problems solved by technology

[0003] In this way, for the whole control system, it is bound to be a complex control system, and for some specific use occasions, such as oil depots, explosive filling and other occasions with explosion-proof requirements, due to the need for electrical signals, the existing reversing valve Unable to meet explosion-proof requirements
Some equipment requires a small overall size, etc. In these occasions, the loop control system is very difficult

Abstract

The invention discloses a push-pull interconnected-control delay-pulse combined reversing valve. Two sides of the notch of the valve are provided with a pneumatic device and an airway opening and closing device; an air inlet is communicated with the pneumatic device and the airway opening and closing device and used for driving the pneumatic device to move; the pneumatic device is used for pushing the airway opening and closing device to realize the communication of the air inlet with a second airway; the second airway is connected with a second vale rod through a first valve rod; the other end of the second valve rod is communicated with the outside through the first valve rod; the air inlet is connected with a second output port through the second valve rod; the second output port is communicated with a first air outlet through a first output port and the second valve rod; a second air outlet is communicated with the second valve rod; one end of the first valve rod is connected between the second valve rod and the second output port; and the other end is connected between the second valve rod and the first output port; the fist valve rod can be made to move to change the movement direction of the second valve rod; and the second valve rod can be made to move to change the direction of the air from the first output port and the second output port. The push-pull interconnected-control delay-pulse combined reversing valve can reverse automatically and circularly without being controlled by the external signal.

Description

technical field [0001] The invention relates to a combined pneumatic reversing valve, in particular to a push-pull interconnection control delay pulse combined reversing valve, which belongs to components in the field of pneumatic technology automation. Background technique [0002] All kinds of pneumatic components developed by pneumatic technology are widely used in production equipment or production lines in various industries, while existing various directional valves, such as electromagnetic directional valves, machine-controlled directional Reversing valves, etc., in order for the reversing valve to produce reversing action, it is necessary to give valve control signals externally to produce reversing. For example, the solenoid valve is controlled by a PLC programmable controller, which is to program various programs for the PLC. , and then send a signal to the solenoid valve. All kinds of machine-controlled valves also need an external touch signal to be transmitted t...
