Background technique
Along with the development of science and technology, the popularity rate of machining equipment or construction equipment is also more and more higher, substantially increases the production and processing ability of people, especially can replace artificial automatically processing device, looks at the parent that its long ability to work receives people greatly.Pneumatic element and pneumatic control system are a kind of devices that air pressure can be converted into mechanical energy, because structure is simple, maintain easily, with low cost, advantages such as environmental pollution is little and a large amount of for needing in the process equipment of mechanical motion.In the course of the work, wherein the movable part of pneumatic element moves around these equipment under the control action of pneumatic control system, thus realizes the drived control function performing pneumatic element.
The exhausting loop of the pneumatic control system in existing equipment only has a series flow control valve similar to drive circuit, and the motion speed of pneumatic element is regulated by series flow control valve.In the exhaust process of pneumatic element, the movable part of pneumatic element does not need external acting, for improving motion speed and the work efficiency of equipment, be generally that acceleration scheme is taked to exhausting loop, but when series flow control valve is adjusted to maximum time, the motion speed of pneumatic element also just reach maximum, and cannot regulate further, limit compressed-air actuated exhaust velocity, had a strong impact on the motion speed of pneumatic element, defect is obvious.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of increase pressurized air exhaust velocity, effectively improves the Pneumatic actuator with quick exhaust function of motion speed.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: a kind of Pneumatic actuator with quick exhaust function, comprise air conditioning unit, major loop solenoid valve, first series flow control valve, second series flow control valve and pneumatic element, it is characterized in that: described air conditioning unit, first series flow control valve is all connected with major loop solenoid valve with the second series flow control valve, first series flow control valve and the second series flow control valve connect hole and second respectively and connect hole and be connected with first of pneumatic element, described second connects between hole and the second series flow control valve and is connected with exhaust series flow control valve, this exhaust series flow control valve is connected with exhaust solenoid valve.
Wherein, the moisture separator that described air conditioning unit comprises overflow reduction valve and is connected with overflow reduction valve, this overflow reduction valve is connected with described major loop solenoid valve.
Wherein, pressure gauge is connected with between described overflow reduction valve and described major loop solenoid valve.
Wherein, described major loop solenoid valve is two-position four-way solenoid valve, and this two-position four-way solenoid valve is connected with the first baffler.
Wherein, described exhaust solenoid valve is connected with the second baffler.
Wherein, described pneumatic element is cylinder.
Beneficial effect of the present invention is: the invention provides a kind of Pneumatic actuator with quick exhaust function, and the first series flow control valve and the second series flow control valve are respectively used to exhaust velocity when motion speed when adjusting cylinders piston rod externally does work and return.By being vented the setting of series flow control valve and exhaust solenoid valve, the basis in conventional exhaust loop increasing a Quick air-discharge loop, greatly increases compressed-air actuated exhaust velocity; Due to the setting of major loop solenoid valve, directly can control the opening and closing in the above-mentioned Quick air-discharge loop set up, further increase speed of response and the motion speed of pneumatic element, improve the manufacturing efficiency of pneumatic equipment.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that mode of execution is mentioned not is limitation of the invention.
As shown in Figure 1, a kind of Pneumatic actuator with quick exhaust function, comprise air conditioning unit 1, major loop solenoid valve 2, first series flow control valve 3, second series flow control valve 4 and pneumatic element 5, described air conditioning unit 1, first series flow control valve 3 is all connected with major loop solenoid valve 2 with the second series flow control valve 4, first series flow control valve 3 and the second series flow control valve 4 connect hole and second respectively and connect hole and be connected with first of pneumatic element 5, described second connects to be connected with between hole and the second series flow control valve 4 and is vented series flow control valve 6, and this exhaust series flow control valve 6 is connected with exhaust solenoid valve 7.
In actual applications, the air conditioning unit 1 had in the Pneumatic actuator of quick exhaust function is connected with source of the gas, pressurized gas enters described major loop solenoid valve 2 after the preliminary treatment of air conditioning unit 1, major loop solenoid valve 2 realizes the real-time switching of air inlet and exhaust under the effect of control circuit, and the air pressure of air inlet and exhaust the most at last can be transferred to pneumatic element 5 through the first series flow control valve 3 and the second series flow control valve 4, the described pneumatic element 5 of the present embodiment is cylinder.First series flow control valve 3 and the second series flow control valve 4 are respectively used to exhaust velocity when motion speed when adjusting cylinders piston rod externally does work and return.By being vented the setting of series flow control valve 6 and exhaust solenoid valve 7, the basis in conventional exhaust loop increasing a Quick air-discharge loop, greatly increases compressed-air actuated exhaust velocity; Due to the setting of major loop solenoid valve 2, directly can control the opening and closing in the above-mentioned Quick air-discharge loop set up, further increase speed of response and the motion speed of pneumatic element 5, improve the manufacturing efficiency of pneumatic equipment.
