Description

Technical Field

[0001] This utility model relates to the field of pneumatic motor technology, specifically a pneumatic motor with a pneumatic control valve island. Background Technology

[0002] Many devices driven by pneumatic motors use a single air source as their power source. Air is supplied to the pneumatic motor via a pneumatic control valve island, causing the motor to operate. The pneumatic motor then transmits the aerodynamic power back to the control valve island to commutate the motor, resulting in continuous reciprocating motion. This solution is widely used in industrial fields such as automotive adhesive application, machining, and electronic equipment manufacturing, achieving continuous and uninterrupted reciprocating motion powered by a single air source.

[0003] Existing pneumatic valve island designs, such as the Airtac ESV+EAV series, while compact and versatile, require consideration of numerous installation and connection accessories, such as mounting plates, air pipes, and pipe connectors, when used with pneumatic motors. This results in a bulky system, cumbersome assembly steps, and increased installation time and quality risks. Furthermore, factors such as vibrations during transportation and operation, the factory's gas environment, and improper shutdown and restart procedures can cause misalignment of the pneumatic directional control valve core, leading to pneumatic motor malfunction. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pneumatic motor with a pneumatic control valve island with touch control. By setting up a pneumatic control valve island with touch control that is easy to assemble, simple in structure, small in size, and reliable in operation, the assembly difficulty and the technical requirements of personnel are reduced. In the event of failure of the pneumatic reversing control valve, the control mode is switched from pneumatic control to touch control, and the valve core is quickly returned to its original position, thereby guiding the pneumatic reversing control valve to work normally. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic motor with a pneumatic control valve island, comprising an extended valve seat, a pneumatic control valve mounted on the upper side of the extended valve seat, and a pneumatic motor disposed on the lower side of the extended valve seat.

A button end cap is disposed outside the left button. Wear-resistant rings are fitted on the outer ring sides of both ends of the first valve core.

[0006] Furthermore, the expansion valve seat has an air inlet and an air outlet inside, a rear cover is provided on one side of the pneumatic motor, and a front cover is provided on the other side of the pneumatic motor.

[0007] Furthermore, both the front cover and the rear cover are provided with pilot valve end caps at the upper center position, and a valve body is provided on one side of the pilot valve end cap, with a second valve core passing through the inside of the valve body.

[0008] Furthermore, a spring is provided on the inner side of the second valve core, a second piston ring is sleeved on the outer ring side of the second valve core, and a fourth O-ring is provided on the side of the valve body facing the pilot valve end cap.

[0009] Furthermore, a No. 5 O-ring is fitted on the outer ring side of the end of the No. 2 valve core away from the pilot valve end cap, a No. 6 O-ring is provided on the outer ring side of the No. 2 valve core near the No. 5 O-ring, and a No. 2 wear-resistant ring is fitted on the outer ring side of the No. 2 valve core near the No. 6 O-ring.

[0010] Furthermore, a third piston ring is provided on the outer ring side of the middle position of the second valve core, and a shaft is provided at the center of the pneumatic motor, with a piston sleeved on the outer side of one end of the shaft.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This embodiment provides a technical solution: a pneumatic motor with a pneumatic control valve island, including an extended valve seat 10, a pneumatic control valve 1 installed on the upper side of the extended valve seat 10, and a pneumatic motor 9 disposed on the lower side of the extended valve seat 10. A first valve core 2 is disposed inside the pneumatic control valve 1. A first piston ring 8 is sleeved at the center of the first valve core 2. An annular valve sleeve 5 is sleeved outside the first valve core 2. A first O-ring 6 is sleeved at one end of the first valve core 2. A second O-ring 7 is disposed on one side of the first O-ring 6. A right button 11 is disposed at one end of the first valve core 2. A third O-ring 12 is sleeved on the outer ring side of the right button 11. A left button 13 is disposed at the end of the first valve core 2 away from the right button 11. A button end cap 3 is disposed outside the left button 13. A first wear-resistant ring 4 is sleeved on the outer ring side of both ends of the first valve core 2.

[0019] The expansion valve seat 10 has an air inlet and an air outlet inside. The pneumatic motor 9 has a rear cover 14 on one side and a front cover 16 on the other side.

[0020] Both the front cover 16 and the rear cover 14 are provided with pilot valve end caps 18 at the center of the upper part. A valve body 19 is provided on one side of the pilot valve end cap 18, and a second valve core 20 is inserted through the inner side of the valve body 19.

[0021] A spring 21 is provided on the inner side of the second valve core 20, and a second piston ring 22 is sleeved on the outer ring side of the second valve core 20. A fourth O-ring 23 is provided on the side of the valve body 19 facing the pilot valve end cover 18.

[0022] A No. 5 O-ring 24 is fitted on the outer ring side of the No. 2 valve core 20 away from the pilot valve end cover 18. A No. 6 O-ring 25 is fitted on the outer ring side of the No. 2 valve core 20 near the No. 5 O-ring 24. A No. 2 wear-resistant ring 26 is fitted on the outer ring side of the No. 2 valve core 20 near the No. 6 O-ring 25.

[0023] A piston ring 27 is provided on the outer ring side of the middle position of the valve core 20. A shaft 17 is provided at the center of the pneumatic motor 9. A piston 15 is sleeved on the outer side of one end of the shaft 17.

[0024] The working principle of the pneumatic motor with a touch-controlled pneumatic valve island provided by this utility model is as follows: Figures 1-3 As shown, Figure 2 With valve core 2 at the right end, compressed air is input through port P of the expansion valve seat 10. This compressed air passes through the pneumatic control valve 1 and the working port A of the expansion valve seat 10, and through the air path at port A of the expansion valve seat 10, it is supplied to port A1 of the pneumatic motor 9, pushing piston 15 of the pneumatic motor 9 to the right. When piston 15 reaches the right end, it pushes valve core 20 of the pilot valve in view II, connecting P21 and P22. Air source P is input from the expansion valve seat 10 through the P port air path to port P2 of the pneumatic control valve 1, pushing valve core 2 to the left end. This connects the P port of the expansion valve seat 10 with the working port A1 of the pneumatic motor 9. Port B is connected and disconnected from working port A. Compressed air passes through working port B of the expansion valve seat 10 and is delivered to the pneumatic motor 9 through port B1, pushing the piston 15 of the pneumatic motor 9 to the left. When the piston 15 moves to the left end, it pushes the second valve core 20 in view II, so that P11 and P12 are connected. The air source P passes through the air path of port P from the expansion valve seat 10, enters the connected P11 and P12, passes through the air path of port P1, and is input to port P1 of the pneumatic control valve 1 to control the air source. This pushes the first valve core 2 of the pneumatic control valve 1 to the right end. The above cycle is repeated, and the pneumatic motor 9 pushes and pulls continuously.

[0025] When valve core 2 is in the middle position, compressed air from a single air source enters port P of pneumatic control valve 1 through port P in expansion valve seat 10. Under the action of piston ring 8, air source P is not connected to working ports A and B. There is no air power output from working ports A and B of pneumatic control valve 1, and no air power input from working ports A1 and B1 of pneumatic motor 9. Pneumatic motor 9 does not operate.

[0026] Pushing the left button 13 on the pneumatic control valve 1 moves the first valve core 2 to the right. Compressed air from a single air source enters the P port of the pneumatic control valve 1 through the P port of the expansion valve seat 10. The air source P is connected to the working port A. The working port A outputs pneumatic power. The A port of the expansion valve seat 10 delivers the input compressed air through the A port air path to the A1 port. The piston 15 of the pneumatic motor 9 moves to the right. At the same time, the compressed air in the right chamber of the pneumatic motor 9 passes through the B1 working port of the pneumatic motor 9, through the B port air path, and is discharged through the expansion valve seat 10 and the working port B and exhaust port S of the pneumatic control valve 1.

[0027] Pushing the right button 11 of the pneumatic control valve 1 moves the first valve core 2 to the left. Pushing the left button 13 returns it to the initial position. Compressed air from a single air source enters the P port of the pneumatic control valve 1 through the P port of the expansion valve seat 10. The air source P is connected to the working port B. The working port B outputs air power. The B port of the expansion valve seat 10 delivers the input compressed air through the B port air path to the B1 port. The piston 15 of the pneumatic motor 9 moves to the left. At the same time, the compressed air in the left chamber of the pneumatic motor 9 is discharged through the A1 working port of the pneumatic motor 9, through the A port air path, through the expansion valve seat 10 and the working port A and exhaust port R of the pneumatic control valve 1.

[0028] Pushing the right button 11 or left button 13 of the pneumatic control valve 1 achieves the purpose of switching the airflow direction. This activates the control air source P1 or P2 through the working ports A and B.
