Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic valves, in particular to a transversely controlled pneumatic valve. Background Art

[0002] Compressed air is used to push the multiple groups of pneumatic pistons in the actuator to move, and the force is transmitted to the characteristics of the crossbeam and the inner curved track to drive the hollow spindle to rotate. The compressed air disc is transmitted to each cylinder, and the inlet and outlet positions are changed to change the rotation direction of the spindle. According to the rotation torque required by the load (valve), the number of cylinder combinations can be adjusted to drive the load to work. The two-position five-way solenoid valve is usually used in conjunction with a double-acting pneumatic actuator. The two-position valve has two controllable positions: open-closed, and the five-way valve has five channels for ventilation, one of which is connected to the air source, two are connected to the inlet and outlet of the external air chamber of the double-acting cylinder, and two are connected to the inlet and outlet of the internal air chamber. The specific working principle can refer to the working principle of the double-acting pneumatic actuator.

[0003] The patent publication number is CN109027318A, a Chinese invention patent published on December 18, 2018, which discloses a pneumatic valve with a relatively simple overall structure. The internal groove can connect the first channel with the second channel or connect the second channel with the third channel or close each channel, but it uses a longitudinally closed structure. Although it can isolate the fluid, the stability of the longitudinal closure is poor. Utility Model Content

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] As Figures 1-6 shown, the pneumatic valve with lateral control in this embodiment includes a protective shell and a valve housing frame. A connecting control seat 2 is fixed at the top of the protective shell. The bottom of the valve housing frame sequentially penetrates through the connecting control seat 2 and the protective shell. The connecting pipe 5 is connected to the protective shell. Inside the valve housing frame, a first sealing plate 1, a second sealing plate 7, a lifting adjustment disc 11 and a mounting disc 25 are sequentially arranged from top to bottom. The first sealing plate 1 is fixed to the top of the valve housing frame, and the second sealing plate 7 is fixed to the bottom of the valve housing frame; the top of the limiting connecting rod 10 is fixed to the bottom of the first sealing plate 1. The bottom of the limiting connecting rod 10 sequentially penetrates through the lifting adjustment disc 11 and the mounting disc 25 and then extends into the support bottom guard 26. The bottom of the support bottom guard 26 is fixed to the top of the second sealing plate 7. A second control spring 27 is arranged on the outer periphery of the support bottom guard 26; the lifting adjustment disc 11 and the mounting disc 25 are both slidably matched with the valve housing frame and the limiting connecting rod 10. A pushing rod 14 is fixed between the lifting adjustment disc 11 and the mounting disc 25. The top of the mounting disc 25 is fixed to the magnetic insertion rod 28 through a linkage component. The magnetic insertion rod 28 is magnetically connected to the limiting magnetic ring 12. A sealing sleeve 6 is arranged on the outer peripheries of the magnetic insertion rod 28 and the limiting magnetic ring 12; a connecting air seat 9 is arranged above the lifting adjustment disc 11; when the connecting pipe 5 is closed, the height of the second control spring 27 is higher than that of the support bottom guard 26. When the connecting pipe 5 is opened, the connecting air seat 9 discharges air and separates the magnetic insertion rod 28 and the limiting magnetic ring 12 through the lifting adjustment disc 11, the mounting disc 25 and the linkage component.

[0028] The displacement of the docking control support 24 can drive the telescopic connecting rod 20 to move by bending the guide rod 22 and articulating the guide rod 21. The telescopic connecting rod 20 is fixed to the magnetic insertion rod 28. At the same time, the magnetic insertion rod 28 is connected to the limiting mounting ring 19 in a limited way through the first control spring 18. The magnetic insertion rod 28 is limited by the bottom of the first protective shell 15, so that the magnetic insertion rod 28 can only perform lateral linear motion. At this time, the magnetic insertion rod 28 moves towards the center, and the first control spring 18 is compressed. At this time, a gap channel is formed between the magnetic insertion rod 28 and the first protective shell 15, and the fluid can flow in. The symmetrically arranged magnetic insertion rods 28 can also open the channel. The right side of the magnetic insertion rod 28 is designed with an opening, and the left side of the magnetic insertion rod 28 is closed. When the magnetic insertion rod 28 is located at the center of the limiting magnetic ring 12, the valve is closed at this time. When the magnetic insertion rod 28 reaches the right side of the limiting magnetic ring 12, the valve is opened at this time.

[0029] Further, the linkage assembly includes a first control spring 18, a limiting mounting ring 19, a telescopic connecting rod 20, a bending guide rod 22 and a docking control support 24. The bottom of the docking control support 24 is fixed to the top of the mounting plate 25. The top of the docking control support 24 is connected to one end of the bending guide rod 22. The other end of the bending guide rod 22 is fixed to one end of the telescopic connecting rod 20 through the articulated guide rod 21. The other end of the telescopic connecting rod 20 is fixed to the magnetic insertion rod 28. The outer wall of the limiting mounting ring 19 is fixed to the valve housing frame. One end of the first control spring 18 is fixed to the limiting mounting ring 19, and the other end of the first control spring 18 is fixed to the magnetic insertion rod 28.

[0030] The gas is compressed and introduced, conducted to the position of the communication gas seat 9 through the communication control seat 2, and introduced to the upper end of the lifting adjustment disc 11. At this time, the gas presses the lifting adjustment disc 11, so that the lifting adjustment disc 11 moves downward on the limiting connecting rod 10. The lifting adjustment disc 11 is connected to the mounting plate 25 through the push rod 14, so that the mounting plate 25 is pressed and adjusted on the limiting connecting rod 10.

[0031] Further, the protective shell includes a first protective shell 15 in the upper layer and a second protective shell 23 in the lower layer. The valve housing frame includes a first valve housing frame 16 in the upper layer and a second valve housing frame 17 in the lower layer. The inner diameter of the first valve housing frame 16 is smaller than the inner diameter of the second valve housing frame 17. The top of the limiting disc 13 is fixed to the lifting adjustment disc 11 through the push rod 14. The bottom of the limiting disc 13 is fixed to the mounting plate 25 through the push rod 14. The limiting disc 13 is slidably matched with the second valve housing frame 17 and the limiting connecting rod 10. When closing the closed communication pipe 5, the top of the limiting disc 13 abuts against the bottom of the first valve housing frame 16.

[0032] Further, the gas pipeline is arranged inside the first protective shell 15. One end of the gas pipeline is communicated with the bottom of the inner cavity of the first valve housing frame 16, and the other end of the gas pipeline is communicated with the inner cavity of the second protective shell 23.

[0033] Further, an air pump chamber 8 is fixed to the top of the protective shell, and the air pump chamber 8 is communicated with a communicating air seat 9.

[0034] Further, a docking mounting seat 3 is fixed to the side wall of the protective shell, and a lead seat 4 is fixed to the bottom of the docking mounting seat 3.

[0035] Further, pressure detectors 29 are arranged on both communicating pipes 5 at both ends of the pneumatic valve.

[0036] The pressure detector 29 can perform pressure detection work, facilitating real-time monitoring of the pressure condition in the communicating pipe 5 and avoiding pipeline leakage incidents.

[0037] The usage method of the present utility model is as follows:

[0038] The user combines the communicating control seat 2, the docking mounting seat 3, and the lead seat 4 as a whole, and then docks and installs the overall structure with an external pipe through the communicating pipe 5. The communicating control seats 2 are symmetrically arranged. The lead seat 4 is connected to an external power supply. The lead seat 4 enables the communicating control seat 2 to work through the docking mounting seat 3, and simultaneously enables the communicating control seat 2 to work. At this time, the air pump chamber 8 also follows to work. The gas is compressed and introduced, conducted to the position of the communicating air seat 9 through the communicating control seat 2, and introduced to the upper end of the lifting adjustment disc 11. At this time, the gas presses the lifting adjustment disc 11, causing the lifting adjustment disc 11 to move downward on the limiting connecting rod 10. The lifting adjustment disc 11 is connected to the mounting disc 25 through the push rod 14, enabling the mounting disc 25 to be pressed and adjusted on the limiting connecting rod 10. A docking control support 24 is fixedly arranged on the mounting disc 25, and simultaneously drives the docking control support 24 to follow for adjustment. The displacement of the docking control support 24 can drive the telescopic connecting rod 20 to move by pulling the bending guide rod 22 and the articulated guide rod 21. The telescopic connecting rod 20 is fixed to the magnetic insertion rod 28. At the same time, the magnetic insertion rod 28 is limitedly connected to the limiting mounting ring 19 through the first control spring 18. The magnetic insertion rod 28 is limited by the bottom of the first protective shell 15, enabling the magnetic insertion rod 28 to only perform horizontal linear motion. At this time, the magnetic insertion rod 28 moves towards the center, and the first control spring 18 is compressed. At this time, a gap channel is formed between the magnetic insertion rod 28 and the first protective shell 15, and the fluid can pass through. The symmetrically arranged magnetic insertion rods 28 can also open the channel, enabling the fluid to enter the position of the second protective shell 23 through the first communicating pipe 5 and then be discharged through another communicating pipe 5. After completion, as the air pressure on the lifting adjustment disc 11 decreases, the second control spring 27 can push the mounting disc 25 to reset, and at the same time, the limiting magnetic ring 12 can adsorb and reset the magnetic insertion rod 28, thereby closing the valve body and completing the work.
