Description

Technical Field

[0001] The invention relates to the technical field of solenoid valves, in particular to a solenoid valve with a quick exhaust function. Background Art

[0002] The five-way solenoid valve is usually used to control double-acting cylinders. It has two air inlets, two working ports and a common exhaust port. When the valve is switched, the unused working ports release gas through the exhaust port.

[0003] The exhaust speed of the five-way solenoid valve is closely related to its use efficiency, especially in the pneumatic system. The exhaust speed directly affects the action response time of the actuator (such as the cylinder) and the working efficiency of the overall system. If the exhaust speed is slow, the reset or action switching of the cylinder or actuator will be delayed, affecting the working rhythm. Slow exhaust may cause the residual air pressure to be unable to be released quickly, thereby interfering with the next operation of the system or causing malfunction. In high-frequency operation scenarios (such as automation equipment), slow exhaust speed will lead to a decrease in the operating rhythm and reduce the overall production efficiency. Slow exhaust may cause pressure imbalance at both ends of the cylinder, increase wear of mechanical parts, and affect equipment life.

[0030] Reference Figure 2 As shown, the exhaust bin 4 is connected with a guide frame 20. After the exhausted air enters the exhaust bin 4, it can flow smoothly to the exhaust frame 17 through the guidance of the guide frame 20 and be discharged. A through hole is opened on one side of the exhaust bin 4 corresponding to the exhaust frame 17, and a support frame 41 is connected to the inner side of the through hole. A rotating shaft 21 is rotatably arranged between the support frame 41 and the inner wall of the exhaust bin 4.

One side of the through hole frame 23 is connected with an air pusher blade 24. When the driven gear 22 is driven by the driving gear 802, the through hole frame 23 is driven to rotate through the rotating shaft 21, thereby driving the air pusher blade 24 to rotate, thereby accelerating the flow speed of the air, thereby accelerating the exhaust.

[0031] Reference Figure 2 and Figure 8 As shown, the tops of the air inlet connecting chamber 3 and the exhaust chamber 4 are both connected with connecting plugs 25, and are connected to the air inlet and exhaust port at the bottom of the valve body 1 through the connecting plugs 25. The exhaust chamber 4 can be directly inserted into the valve body 1, and the air inlet connecting chamber 3 is threadedly connected to the valve body 1 through the connecting plug 25 to ensure the working stability of the air inlet.

[0032] Reference Figure 8 As shown, an air collecting hopper 301 is connected to the bottom end of the inner wall of the air inlet connecting bin 3. The air collecting hopper 301 is conical in shape, with two groups of fan blades 7 located above the air collecting hopper 301.

[0033] Reference Figure 4 and Figure 5 As shown, one end of the exhaust pipe 14 and the connecting pipe 19 are both connected with a one-way valve, and the middle end of the exhaust gas extraction pipe 16 is connected with a control valve. When the piston 12 slides up and down in the cylinder 11, the air in the negative pressure gas tank 13 will be extracted through the exhaust pipe 14, thereby forming a negative pressure in the negative pressure gas tank 13, and the extracted gas will be discharged to the cleaning rack 18 through the connecting pipe 19. The setting of the one-way valve can ensure the singleness of the air flow direction.

[0034] Reference Figure 1 and Figure 2 As shown, a muffler 171 is connected to one end of the exhaust rack 17, and the muffler 171 is located on the inner side of the cleaning rack 18, wherein the muffler 171 can be a solenoid valve muffler or a solenoid valve noise reducer in the prior art, and a plurality of exhaust holes are provided on the inner side of the cleaning rack 18, and air can be blown to the surface of the muffler 171 to prevent dust from adhering. At the same time, the gas blown out of the cleaning rack 18 will not have too high an air pressure, and will not affect the airflow discharged from the exhaust rack 17 or the muffler 171.

[0035] Reference Figure 6 and Figure 7 As shown, the clutch mechanism 8 includes a sealing box 81 and a fixed disk 83. One end of the rotating shaft 6 extends into the sealing box 81 and is slidably provided with a movable disk 82. The outer ring of the movable disk 82 is rotatably provided with a ring frame 84. The surface of the ring frame 84 is connected with multiple groups of connecting bolts 85. One side of the connecting bolt 85 is connected with a connecting rod 86. One side of the connecting rod 86 is connected with an iron ring 87. The other side of the connecting bolt 85 is connected with a traction spring 88. The other end of the traction spring 88 is fixedly provided on one side of the inner wall of the sealing box 81. One side of the inner wall of the sealing box 81 is connected An electromagnet 89 is connected, a plurality of limiting teeth are connected to one side of the movable disk 82, and a plurality of engaging grooves are opened on one side of the fixed disk 83. When the electromagnet 89 is energized to generate magnetic attraction, the iron ring 87 is magnetically attracted to the electromagnet 89 and fits the iron ring 87. While moving, the connecting bolt 85 and the ring frame 84 are driven to move through the connecting rod 86, and the movable disk 82 is moved along the rotating shaft 6, so that the movable disk 82 fits the fixed disk 83. Due to the connection between the limiting teeth and the engaging grooves, the movable disk 82 and the fixed disk 83 rotate synchronously. Figure 5It can be seen that a slide groove is provided at one end of the rotating shaft 6, and a clamping block is connected to the inner circle of the movable disk 82 and is slidably connected to the slide groove, so that when the rotating shaft 6 rotates, the movable disk 82 can be driven to rotate, and the movable disk 82 can slide along the rotating shaft 6.

[0036] Reference Figure 2 and Figure 7 As shown, a circular shaft 801 is connected to one side of the electromagnet 89, and the other end of the circular shaft 801 extends through the exhaust chamber 4 and is connected to a driving gear 802. One side of the driving gear 802 is meshed with the driven gear 22. When the movable disk 82 drives the fixed disk 83 to rotate, the driving gear 802 can be driven to rotate through the transmission of the circular shaft 801, thereby driving the driven gear 22 to rotate.

[0037] Reference Figure 4 As shown, the protective mechanism 15 includes a connecting plate 151, one side of which is connected to a plurality of support rods 152, and the other end of the support rod 152 is connected to a pressure sensor 153, which is fixedly arranged on the inner side of the mounting groove, and one end of the exhaust gas extraction pipe 16 passes through the connecting plate 151 and is connected to the negative pressure gas tank 13, wherein the connecting plate 151 is fixedly connected to one side of the negative pressure gas tank 13, which can be adhesively bonded or welded, and the support rod 152 provides supporting force for the connecting plate 151, and the connecting plate 151 is fixedly connected to one side of the negative pressure gas tank 13 to avoid deformation when the negative pressure gas tank 13 is drawn into negative pressure, which will affect the balance of the connecting plate 151 supported by the four support rods 152 when deformation occurs, and the pressure sensor 153 connected to the bottom end of the support rod 152 will detect the pressure, and when the pressure changes, it means that the negative pressure gas tank 13 has been deformed, and it is necessary to pay attention to safe and timely exhaust, or adjust the setting value of the control valve at the middle end of the exhaust gas extraction pipe 16.

[0038] Axle seats 601 are connected to both sides of the inner wall of the air inlet connection compartment 3 , and one end of the rotating shaft 6 is rotatably arranged with the shaft seat 601 to ensure the supporting effect of the rotating shaft 6 on the fan blade 7 .

[0039] The implementation principle of the present application is as follows: when the present invention is in use, when air is injected into the air inlet connection chamber 3 through the air inlet pipe joint 5, the air will be accelerated when passing through the air collecting bucket 301, and then the fan blade 7 will be blown to rotate, thereby driving the rotating shaft 6. While rotating, the rotating shaft 6 will rotate through the crankshaft end 61 at one end, thereby driving the cam frame 9, so that the connecting rod 10 brings the piston 12 to move up and down in the cylinder 11, so as to continuously extract the air in the negative pressure gas tank 13 through the exhaust pipe 14, so that the negative pressure gas tank 13 is kept in a negative pressure state, and at the same time, the clutch state between the rotating shaft 6 and the circular shaft 801 can be controlled by the clutch mechanism 8, so that the rotating shaft 21 in the exhaust chamber 4 rotates, The pusher blades 24 are driven to rotate. When the exhaust bin 4 on either side is in the exhaust state, the clutch mechanism 8 on the corresponding side is merged and connected, driving the pusher blades 24 in the corresponding exhaust bin 4 to rotate, thereby accelerating the flow of air. Since there is no gas to be discharged from the other exhaust bin 4, the clutch mechanism 8 on the corresponding side can be disconnected. When the valve is switched, some high-pressure gas in the working port on the other side has not been discharged. At this time, the control valve on the side of the exhaust gas extraction pipe 16 can be opened. The negative pressure gas tank 13 is in a negative pressure state, and the residual high-pressure gas inside can be extracted through the exhaust gas extraction pipe 16 to reduce the residual high-pressure gas inside the valve body 1.
