Description

Technical Field

[0001] The present application relates to the field of airtightness detection, and in particular to an active hybrid drive solenoid valve driving method and device. Background Art

[0002] With the development of industrial automation and intelligence, solenoid valves are increasingly used in gas sealing detection. As a key component for gas sealing detection, solenoid valves act as ventilation switches, detecting the sealing performance of equipment or systems by controlling the flow and cutoff of gas. Intelligent solenoid valves can not only achieve remote control and automated operation, but also be networked with other devices, thereby improving the intelligence level and work efficiency of the system.

[0003] In high gas tightness testing, the solenoid valve needs to be able to withstand higher pressures. This usually requires the solenoid valve to have greater power to drive the movement of the piston or valve core and perform high-frequency switching to ensure that it works normally and reliably under high-pressure conditions. In order to provide sufficient power, a high-power solenoid coil is usually required to drive the solenoid valve. However, ordinary solenoid coils have limited power and load capacity, and are prone to overload, heating, or even damage under high-frequency switching and high-pressure conditions.

[0086] See also Figure 1-Figure 14 The embodiment of the present application provides a method for driving an active hybrid drive solenoid valve 100, the steps comprising:

[0087] S10, the electromagnetic coil 10 is energized and generates electromagnetic force.

[0088] S20 , the electromagnetic force drives the first valve core 20 away from the control device 30 , and opens the first gas path system 50 .

[0089] S30 , the gas enters the first gas circuit system 50 and flows through the lower chamber 322 in the control device 30 to open the second gas circuit system 60 in the ventilation device 40 .

[0090] S40 , the electromagnetic force drives the second valve core 70 and drives the steel ball 71 connected to the second valve core 70 to slide in a direction close to the lower chamber 322 to open a passage connecting the lower chamber 322 to the upper chamber 321 in the control device 30 .

[0091] S50 , the gas flows from the lower chamber 322 to the upper chamber 321 , and the gas is discharged from the upper chamber 321 through the pressure relief channel 35 connected to the upper chamber 321 .

[0092] S60, the electromagnetic coil 10 is powered off, the first valve core 20 is connected to the control device 30, and the first gas path system 50 is closed. The electromagnetic valve stops working. The electromagnetic valve comprises: an electromagnetic coil 10, a first valve core 20 and a second valve core 70 respectively connected to the electromagnetic coil 10, and a steel ball 71 fixedly connected to the second valve core 70 and used to isolate the channel connecting the lower chamber 322 to the upper chamber 321, and a ventilating device 40 connected to the end of the control device 30 away from the electromagnetic coil 10.

[0093] Before the detailed description, it should be noted that the first direction F1 is the sliding direction of the piston member 32 .

[0094] Specifically, the electromagnetic force drives the first valve core 20 away from the first through hole 342 in the air inlet 34, and obtains gas to enter the lower chamber 322. The first gas circuit system 50 is disposed in the control device 30. The first gas circuit system 50 is opened. The gas is allowed to flow in the first gas circuit system 50 in the first control device 30.

[0095] The first gas circuit system 50 includes three chambers, namely, the gas chamber 341 of the gas inlet member 34, the lower chamber 322 and the upper chamber 321 isolated by the piston member 32 in the receiving member 31. The gas flows through the gas chamber 341, the lower chamber 322 and the upper chamber 321 in sequence. When the first valve core 20 is fitted and connected with the first through hole 342, the first gas circuit system 50 is closed, and the gas in the first gas circuit system 50 can only enter the gas chamber 341.

[0096] When the electromagnetic coil 10 is energized, an electromagnetic force is generated. The electromagnetic force pushes the first valve core 20 away from the first through hole 342, opens the connection between the air cavity 341 and the first through hole 342, and the gas is obtained to enter the gas path of the lower chamber 322. When the gas enters the lower chamber 322, at the same time, the steel ball 71 isolates the passage from the lower chamber 322 to the upper chamber 321, and the gas pressure of the lower chamber 322 is greater than the gas pressure of the upper chamber 321. The gas pressure of the lower chamber 322 pushes the piston member 32 to slide along the first direction F1 away from one end of the control device 30, and contracts the telescopic member. The telescopic member is fixedly connected to the piston member 32 to drive the piston member 32 to slide.

[0097] After the piston member 32 slides along the first direction F1 away from one end of the control device 30, it is no longer closely connected with the valve gas circuit 62 of the control device 30. The valve gas circuit 62 connects the high-pressure gas chamber 41 and the airtightness detection equipment. The second gas circuit system 60 is opened, and the high-pressure gas circulates in the second gas circuit.

[0098] The steel ball 71 located in the fifth gas path portion 533 abuts against the sixth gas path portion 534, and the steel ball 71 isolates the connection between the fifth gas path portion 533 and the sixth gas path portion 534, so that the lower chamber 322 and the upper chamber 321 are not connected. The electromagnetic coil 10 is energized to generate electromagnetic force. The electromagnetic force drives the second valve core 70, exerting a driving force on the second valve core 70. The second valve core 70 is moved away from the sixth gas path portion 534, still located in the fifth gas path portion 533, but not abutting against the sixth gas path portion 534. After the gas enters the sixth gas path portion 534, it flows through to the upper chamber 321. The gas located in the upper chamber 321 is discharged to the outside through the pressure relief channel 35 connected to the upper chamber 321.

[0099] The pressure relief channel 35 connects the upper chamber 321 to the pressure relief air pipe and is opened in the control device 30. When the pressure relief channel 35 is set as a normally open channel, the gas is continuously discharged from the upper chamber 321, maintaining the gas pressure of the lower chamber 322 greater than the gas pressure of the upper chamber 321.

[0100] The electromagnetic coil 10 is powered off, and the first valve core 20 slides along the first direction F1 close to one end of the first through hole 342 until the first valve core 20 is closely connected with the first through hole 342, closing the first gas path system 50. The electromagnetic valve stops working.

[0101] S20 , the electromagnetic force drives the first valve core 20 away from the control device 30 , and opens the first gas path system 50 .

[0102] Specifically, step S20 includes:

[0103] S21 , the electromagnetic force drives the first valve core 20 away from the first through hole 342 to open the first gas path system 50 .

[0104] The first gas path system 50 is provided inside the control device 30. The control device 30 comprises: an air inlet member 34, a receiving member 31, a piston member 32 and a first telescopic member 33.

[0105] The air inlet member 34 is arranged along the first direction F1, one end of the air inlet member 34 is closely connected to the electromagnetic coil 10, and the other end of the air inlet member 34 is closely connected to the accommodating member 31. An air cavity 341 and a first through hole 342 communicating with the air cavity 341 are provided in the air inlet member 34, and the first through hole 342 can be closely connected to the first valve core 20;

[0106] One end of the accommodation member 31 is connected to the air inlet member 34 , and the other end of the accommodation member 31 is connected to the ventilation device 40 .

[0107] The piston member 32 is connected to the interior of the container 31. The piston member 32 isolates an upper chamber 321 and a lower chamber 322. The upper chamber 321 and the lower chamber 322 are located in the container 31. The first telescopic member 33 is arranged along the first direction F1. One end of the first telescopic member 33 is connected to the container 31, and the other end of the first telescopic member 33 is connected to the piston member 32.

[0108] The first through hole 342 is closely connected to the first valve core 20 , and the first gas path system 50 is closed.

[0109] The first through hole 342 is not in close contact with the first valve core 20 , and the first gas path system 50 is open.

[0110] The electromagnetic coil 10 is not energized, and the first valve core 20 is attached to the first through hole 342 under the action of a spring or other reset device, and the first gas circuit system 50 is closed. After the electromagnetic coil 10 is energized, an electromagnetic force is generated. The electromagnetic force drives the first valve core 20 to move away from the first through hole 342 along the first direction F1, opens the first gas circuit system 50, and the gas enters the gas cavity 341 in the gas inlet 34. The gas enters the lower chamber 322 through the gas cavity 341.

[0111] The working principle of the control device 30 is that after being powered on, electromagnetic force is generated to push the first valve core 20 to move. Under the action of the electromagnetic force, the first valve core 20 moves away from the first through hole 342 to open the gas path system. The first gas path system 50 is connected to the gas inlet part 34, the receiving part 31, and the piston part 32 to ensure smooth gas flow.

[0112] By driving the first valve core 20 with electromagnetic force, fast and accurate gas circuit switch control is achieved, thereby improving the response speed and detection accuracy of the gas sealing detection system.

[0113] Reasonable configuration of the air inlet member 34, the receiving member 31, the piston member 32 and the first telescopic member 33 ensures the stability and reliability of the system structure, and enables long-term stable operation under high pressure and high frequency conditions.

[0114] By the fitting connection between the first valve core 20 and the first through hole 342 , good air tightness is achieved, gas leakage is avoided, and the detection accuracy of the system is improved.

[0115] One end of the first telescopic member 33 is connected to the receiving member 31, and the other end is connected to the piston member 32, and is arranged along the first direction F1. When gas enters the lower chamber 322 and pushes the piston member 32 to move, the first telescopic member 33 provides elastic restoring force to ensure that the piston member 32 can quickly return to the initial position when the gas pressure changes.

[0116] S30 , the gas enters the first gas circuit system 50 and flows through the lower chamber 322 in the control device 30 to open the second gas circuit system 60 in the ventilation device 40 .

[0117] Specifically, step S30 includes:

[0118] S31 , after the first gas path system 50 is ventilated, the gas sequentially flows through the gas inlet member 34 and the lower chamber 322 , the piston member 32 and the upper chamber 321 .

[0119] The first air path system 50 includes a first air intake path 51 , a second air intake path 52 and a third air intake path 53 .

[0120] One end of the first air inlet passage 51 is set as the air inlet end and the gas enters the first air inlet passage 51 , and the other end of the first air inlet passage 51 is connected to the air inlet member 34 and receives the gas, and the gas enters into the air inlet member 34 .

[0121] One end of the second air inlet passage 52 is in communication with the air inlet member 34 , and the other end of the second air inlet passage 52 is in communication with the lower cavity. The second air inlet passage 52 receives the gas in the air inlet member 34 .

[0122] One end of the third air inlet passage 53 is communicated with the lower cavity, and the other end is communicated with the upper cavity. The third air inlet passage 53 receives the gas in the lower cavity.

[0123] The gas first enters the gas inlet member 34 through the first gas inlet path 51, then enters the lower cavity from the gas inlet member 34 through the second gas inlet path 52, and finally enters the upper cavity from the lower cavity through the third gas inlet path 53. The gas flows through each chamber, pushing the piston member 32 to move, thereby opening the second gas path system 60.

[0124] By rationally configuring the first, second and third air inlet paths 53, efficient transmission of gas from the air inlet end to the upper cavity is achieved.

[0125] The flow of gas in each cavity and the change in pressure ensure the precise movement of the piston member 32 , thereby accurately controlling the opening and closing of the second gas path system 60 .

[0126] The design of the first gas circuit system 50 ensures the overall stability and air tightness of the system, and is suitable for high-pressure and high-frequency working scenarios.

[0127] S30 , the gas enters the first gas circuit system 50 and flows through the lower chamber 322 in the control device 30 to open the second gas circuit system 60 in the ventilation device 40 .

[0128] Specifically, step S30 also includes:

[0129] S32, the gas enters the first gas path portion 511 from the gas inlet end, and first flows through the first conversion channel 512 along the first direction F1.

[0130] S33 , the air flows from the first conversion channel 512 to the second gas path portion 513 , then flows to the air cavity 341 communicating with the second gas path portion 513 , and finally flows to the first through hole 342 communicating with the air cavity 341 .

[0131] The first air intake path 51 includes a first air path portion 511 , a second air path portion 513 and a first conversion channel 512 .

[0132] The first gas path portion 511 is opened in the accommodating member 31. The second gas path portion 513 is opened in the air inlet member 34. The second gas path portion 513 is connected to the air cavity 341. The first conversion channel 512 is located in the air inlet member 34.
