Description

Technical Field

[0001] The present invention relates to a pressure detection device, in particular to a pressure regulation device and a pressure regulation method. Background Art

[0002] When calibrating a pressure component to be calibrated (such as a pressure gauge) assembled on a pressure output part through an existing pressure regulation device, first, a required air pressure needs to be set through a pressure control component. Then, a corresponding air pressure is generated by a pressure generating component and the required air pressure is input into the pressure component to be calibrated assembled on the pressure output part. Finally, the pressure component to be calibrated is compared with a standard pressure component to determine the accuracy of the pressure component to be calibrated. However, in the existing pressure regulation device, the compressor generally directly generates pressure through two-stage piston reciprocating motion. However, the gas pressure generated by it is relatively low and the flow rate is small. If high-pressure and large-flow gas needs to be output, it is necessary to increase the piston area or increase the motor speed. With the increase of the piston area and the increase of the motor speed, a high-power and high-torque motor also needs to be used. However, using such a motor will not only waste electric energy, increase noise, increase the volume of the compressor, but also reduce the service life of the motor and the piston seal life. Summary of the Invention

[0003] Aiming at the deficiencies existing in the above problems, the present invention provides a pressure regulation device and a pressure regulation method that can increase the output pressure of the device without using a high-power and high-torque motor to meet the actual calibration requirements.

[0004] To achieve the above object, the present invention provides a pressure regulation device, including a pressure control component, a pressure generating component, a positive pressure pipeline component, a pipeline switching component, a pressure control component and a pressure output part. The pressure control component is electrically connected to the pressure generating component, the positive pressure pipeline component, the pipeline switching component and the pressure control component respectively. The pressure generating component is in pipeline communication with the positive pressure pipeline component, the pipeline switching component, the pressure control component, the pressure control component and the pressure output part;

[0005] The positive pressure pipeline component includes a supercharger electrically connected to the pressure control component and used for boosting a preset pressure, and a preset pressure determination component used for determining a preset pressure value.

[0006] Optionally, the preset pressure determination component includes a pre-pressure cavity and a pressure sensor b disposed inside it and used for collecting the preset pressure value inside the pre-pressure cavity. The pressure sensor b is electrically connected to the pressure control component.

[0007] Optionally, the pre-pressure cavity is respectively in pipeline communication with the pressure generating component and the supercharger, and is arranged in parallel with the supercharger.

[0008] Optionally, the positive pressure pipeline assembly further includes a set air pressure determination assembly located at the output end of the supercharger and communicating with the supercharger pipeline. The set air pressure determination assembly includes a positive pressure cavity and a pressure sensor a disposed inside the positive pressure cavity for collecting the current air pressure value inside the positive pressure cavity. The pressure sensor a is electrically connected to the pressure control assembly.

[0009] Optionally, the pressure control assembly includes a solenoid valve b, a solenoid valve c, a solenoid valve g, and a solenoid valve d respectively electrically connected to the pressure control assembly. The solenoid valve b is located between the supercharger and the positive pressure cavity. The solenoid valve c is located at the output end of the positive pressure cavity and is also in pipeline communication with the pressure output part and the pressure control assembly. The solenoid valve g is located at the output end of the pre-pressure cavity.

[0010] Optionally, the pipeline switching assembly includes a solenoid valve a, a solenoid valve e, and a solenoid valve f. The solenoid valve a is located on the pipeline between the pressure generating component and the supercharger. The solenoid valve e is located on the pipeline between the solenoid valve a and the pre-pressure cavity. The solenoid valve f is located on the pipeline between the solenoid valve e and the pressure generating component.

[0011] Optionally, the pressure control assembly includes a processor, as well as a display screen, a pressure input part, and a pressure detection module respectively electrically connected thereto. The processor is also respectively electrically connected to the pressure control assembly, the pressure sensor a, the pressure sensor b, the pressure generating component, the supercharger, and the pipeline switching assembly.

[0012] Optionally, the positive pressure pipeline assembly is composed of the pressure generating component, the solenoid valve a, the supercharger, the solenoid valve b, the set air pressure determination assembly, the solenoid valve c, the solenoid valve d, the solenoid valve e, the preset pressure determination assembly, and the solenoid valve g that are connected in series.

[0013] Optionally, the pressure control assembly controls the pipeline switching assembly to form a negative pressure pipeline assembly, which is composed of the solenoid valve d, the solenoid valve g, the preset pressure determination assembly, the solenoid valve e, the solenoid valve f, the pressure generating component, and the solenoid valve a that are connected in series.

[0014] The present invention also provides a pressure regulation method, including the following steps:

[0015] Step 1: The pressure control assembly controls the pressure generating component to generate a preset pressure according to the required air pressure and respectively inputs it into the supercharger and the preset pressure determination assembly;

[0016] Step 2: When the pressure control assembly determines that the air pressure inside the preset pressure determination assembly is not less than the preset pressure, it controls the pressure generating component to stop the pressure generating work;

[0017] Step 3: The supercharger boosts the preset pressure to form a boosted air pressure, which is input into the pressure output part through the set air pressure determination component to perform a calibration operation on the standard air pressure component and the air pressure component to be calibrated.

[0018] Optionally, in Step 3, after the boosted air pressure is input into the set air pressure determination component, when the pressure control component determines that the air pressure inside the set air pressure determination component is not less than the required air pressure, the supercharger is controlled to stop the boosting operation.

[0019] Compared with the prior art, the present invention has one of the following advantages:

[0020] By adding a preset pressure determination component to the pressure regulation device, it is possible to determine whether the preset pressure value generated by the pressure generating component reaches the preset pressure value, facilitating the control of the working state of the pressure generating component;

[0021] By adding a supercharger to the pressure regulation device, without the need for a high-power and high-torque motor, the preset pressure generated by the pressure generating component can be boosted to the required pressure, thereby increasing the output pressure of the device, reducing the working pressure of the pressure generating component, and shortening the calibration time for the pressure component to be calibrated to meet the actual calibration requirements;

[0022] By adding a solenoid valve b between the supercharger and the positive pressure cavity in the pressure regulation device, it is possible to prevent the boosted air pressure in the positive pressure cavity from flowing back into the supercharger and avoid a decrease in the air pressure value in the positive pressure cavity;

[0023] By adding a set air pressure determination component to the pressure regulation device, it is possible to determine whether the pressure value generated by the supercharger is greater than the required pressure value, facilitating the control of the working state of the supercharger;

[0030] As Figure 1 shown, the present invention provides a pressure regulating device, including a pressure generating component 1, a pipeline switching component, a pressure control component, a pressure control component 4 and a pressure output section 5. Among them, the pressure control component 4 controls the pipeline switching component to form a positive pressure pipeline component. The pressure control component 4 is electrically connected to the pressure generating component 1, the pipeline switching component, the positive pressure pipeline component and the pressure control component respectively. The pressure generating component 1 is connected to the positive pressure pipeline component, the pipeline switching component, the pressure control component, the pressure control component and the pressure output section 5 through pipelines.

[0031] The pressure control component 4 includes a processor, and a display screen, a pressure input section and a pressure detection module which are electrically connected to it respectively. The processor is also electrically connected to the pressure control component, a set air pressure determination component, the pressure generating component 1 and the supercharger 2 respectively, and is used to control the pressure control component, the set air pressure determination component, the pressure generating component 1 and the supercharger 2. Among them, the pressure input section can select components such as buttons or knobs to input the required pressure value to the processor. The display screen is used to display the current pressure value for easy viewing of the current pressure value.

[0032] The positive pressure pipeline component includes a supercharger 2, a preset pressure determination component and a set air pressure determination component.

[0033] The supercharger 2 is electrically connected to the processor, is connected to the pressure generating component 1 through a pipeline, and is located at the input end of the set air pressure determination component, and is used to increase the preset pressure input by the pressure generating component 1 and input the generated increased pressure into the set air pressure determination component.

[0034] The preset pressure determination component includes a pre - pressure chamber 9 and a pressure sensor b91 disposed inside it for collecting the preset pressure value inside the pre - pressure chamber 9. Among them, the pre - pressure chamber 9 is respectively connected to the pressure generating component 1 and the supercharger 2 through pipelines and is arranged in parallel with the supercharger. The pressure sensor b91 is electrically connected to the processor to input the pneumatic electrical signal corresponding to the preset pressure value collected into the processor.

[0035] The set air pressure determination component includes a positive pressure cavity 3 and a pressure sensor a31 disposed inside it for collecting the current air pressure value inside the positive pressure cavity 3. Among them, the positive pressure cavity 3 is located at the output end of the supercharger 2 and is connected through a pipeline. The pressure sensor a31 is electrically connected to the processor to input the air pressure electrical signal corresponding to the set air pressure value collected into the processor.

[0036] In this embodiment, the pre-pressure cavity 9 is respectively connected to the pressure generating component 1 and the supercharger 2, and is arranged in parallel with the supercharger 2 and the positive pressure cavity 3, so that the preset pressure generated by the pressure generating component 1 can be respectively input into the supercharger 2 and the pre-pressure cavity 9.

[0037] The pipeline switching component includes a solenoid valve a12, a solenoid valve e10, and a solenoid valve f13 that are respectively electrically connected to the processor. The solenoid valve a12 is located on the pipeline between the pressure generating component 1 and the supercharger 2, the solenoid valve e10 is located on the pipeline between the solenoid valve a12 and the pre-pressure cavity 9, and the solenoid valve f13 is located on the pipeline between the solenoid valve e10 and the pressure generating component 1.

[0038] In this embodiment, the solenoid valve a12, the solenoid valve e10, and the solenoid valve f13 are all two-position three-way solenoid valves. Among them, the solenoid valve a12 includes a working port a, a working port b, and a working port c, the solenoid valve f13 includes a working port a, a working port b, and a working port c, and the solenoid valve e10 includes a working port a, a working port b, and a working port c.

[0039] The pressure control component includes a solenoid valve b6, a solenoid valve c7, a solenoid valve g11, and a solenoid valve d8. The solenoid valve b6 is located between the supercharger and the positive pressure cavity 3, the solenoid valve c is disposed at the output end of the positive pressure cavity 3 and is also connected to the pressure output part and the pressure control component through a pipeline, and the solenoid valve g is disposed at the output end of the pre-pressure cavity 9.

[0040] The processor respectively controls the solenoid valve a12 and the solenoid valve e10, so that the working port b in the solenoid valve a12 is connected to the working port a, and the working port a in the solenoid valve e10 is connected to the working port b. At this time, the positive pressure pipeline component is composed of the pressure generating component 1, the solenoid valve a12, the supercharger 2, the solenoid valve b, the set air pressure determination component, the solenoid valve c7, the solenoid valve d8, the solenoid valve e10, the preset pressure determination component, and the solenoid valve g11 connected through pipelines.

[0041] In this embodiment, the solenoid valve b6, the solenoid valve c7, the solenoid valve d8, and the solenoid valve g11 are all pneumatic solenoid valves.

[0042] Since the solenoid valve B6 is arranged on the pipeline between the supercharger 2 and the positive pressure cavity 3 and is connected to the supercharger 2 and the positive pressure cavity 3 respectively through the pipeline. When the processor determines that the pressure in the positive pressure cavity 3 is greater than the required air pressure, the processor controls the solenoid valve B6 to close to prevent the air pressure in the positive pressure cavity from flowing back into the supercharger, and the decrease of the air pressure value in the positive pressure cavity can be avoided.

[0043] After the pressure input part inputs the required pressure value to the processor, the processor controls the pressure generating component 1 to generate a preset pressure. At the same time, the processor controls the working port b of the solenoid valve A12 to communicate with the working port a, the working port a of the solenoid valve E10 to communicate with the working port b, and the solenoid valve B6 and the solenoid valve C7 are in the open state, and the solenoid valve G11 is in the closed state, so that the preset pressure generated by the pressure generating component is respectively input into the supercharger and the pre-pressure cavity through the pipeline.

[0044] The processor is electrically connected to the pressure sensor B91. After the preset pressure generated by the pressure generating component is input into the pre-pressure cavity 9, the pressure sensor B91 collects the pressure electrical signal corresponding to the current preset pressure value in the pre-pressure cavity and inputs the collected pressure electrical signal into the processor, so that the processor processes the current pressure value.

[0045] After receiving the pressure electrical signal, the processor processes it to obtain the corresponding preset pressure value. When the preset pressure value reaches the preset pressure value specified by the processor, the processor controls the pressure generating component to stop the pressure generating operation.

[0046] In addition, since the preset pressure is also input into the pre-pressure cavity, therefore, the preset pressure can be discharged to the outside of the pressure regulating device through the pipeline as needed, and the preset pressure can also be input into the pressure output part through the pipeline.

[0047] The preset pressure is respectively input into the supercharger through the pipeline. The supercharger performs a boosting operation on the preset pressure, and the boosted pressure is input into the positive pressure cavity at its output end through the open solenoid valve B.

[0048] After the boosted pressure is input into the positive pressure cavity, the current pressure inside the positive pressure cavity is collected by the pressure sensor A to generate a pressure electrical signal corresponding to the current pressure, and the pressure electrical signal is input into the processor. The processor processes the pressure electrical signal and inputs it into the display screen for display.

[0049] Among them, the pressure information can be in digital style or graphic style, etc.

[0050] Since the solenoid valve c is in the open state, the pressurized pressure output from the positive pressure chamber can be input into the pressure output section through the solenoid valve c, thereby inputting the pressure into the standard pressure component and the pressure component to be calibrated assembled on the pressure output section, so that the pointer or number in the standard pressure component and the pressure component to be calibrated can change according to the input pressure, and finally display the pressure information corresponding to the required pressure value.

[0051] In addition, the pressure control component also includes a pressure detection module. When the pressurized pressure is input into the pressure output section, a part of the pressure can also be input into the pressure control component, so that this part of the pressure contacts the pressure detection module, so that the pressure detection module can collect the pressure electrical signal output from the solenoid valve c. After the processor processes the pressure electrical signal, the pressure value in this section of the pipeline and the pressure value input into the pressure output section can be obtained.

[0052] Among them, when inputting air pressure into the pressure output section and the pressure control component through the solenoid valve c, the processor can control the size of the valve body opening according to the pressure value collected by the pressure sensor a or the pressure value collected by the pressure detection module, so as to control the pressure storage amount in the positive pressure chamber or the pressure amount input into the pressure output section.

[0053] In addition, after the processor controls the pressure generating component to stop generating pressure, the pressure sensor a of the positive pressure chamber still continuously collects the pressure value in the positive pressure chamber and inputs the pressure electrical signal into the processor. After the processor processes the pressure electrical signal, if it is determined that the current pressure value is less than the required pressure value, it controls the pressure generating component to start the pressure generating operation, the supercharger to start the supercharging operation, and controls the solenoid valve b to change from the closed state to the open state, so as to input the supercharged air pressure into the positive pressure chamber and input pressure into the pressure output section. If it is determined that the current pressure value is not less than the required pressure value, continue to perform the calibration operation on the pressure component to be calibrated until the calibration is completed.

[0054] After completing the calibration operation on the pressure component to be calibrated, the processor can control the solenoid valve d8 to change from the closed state to the open state, so as to discharge the remaining pressure stored in the positive pressure chamber or the remaining pressure stored in the pipeline to the outside of the pressure regulating device. In addition, the solenoid valve d can also remain in the closed state, and the remaining pressure is stored in the positive pressure chamber and the pipeline.

[0055] In this embodiment, the standard air pressure component and the air pressure component to be calibrated are a standard pressure gauge and a pressure gauge to be calibrated, respectively.

[0056] As Figure 2 shown, on the basis of the pressure regulating device described in Figure 1 , the processor in the pressure control component 4 controls the pipeline switching component to form a negative pressure pipeline component.

[0057] Among them, the processor controls the working port c in the solenoid valve e10 to communicate with the working port b, the working port b in the solenoid valve f13 to communicate with the working port a, and the working port b in the solenoid valve a12 to communicate with the working port c, so that the negative pressure pipeline assembly is composed of the solenoid valve d8, the solenoid valve g11, the preset pressure determination component, the solenoid valve e10, the solenoid valve f13, the pressure generating component 1 and the solenoid valve a12 connected by pipelines.

[0058] When it is necessary to detect the negative pressure inside the pre-pressure cavity, the processor controls the solenoid valve d8 and the solenoid valve g11 to be in the closed state, the working port c in the solenoid valve e10 to communicate with the working port b, the working port b in the solenoid valve f13 to communicate with the working port a, and the working port b in the solenoid valve a12 to communicate with the working port c. The pressure generating component pumps out the air pressure in the pre-pressure cavity 9 through pipelines, solenoid valve f and solenoid valve e, and then discharges it to the outside of the pressure regulating device through pipelines and the solenoid valve a12, so as to form a negative air pressure inside the pre-pressure cavity 9.

[0059] At this time, the pressure sensor b91 can collect the air pressure electrical signal corresponding to the current air pressure value in the pre-pressure cavity 9 in real time, or according to a preset time period, or after the pressure generating component stops working, and input the collected air pressure electrical signal into the processor, so that the processor can know the current negative air pressure value inside the pre-pressure cavity 9 according to the air pressure electrical signal, and display the current negative air pressure value through the display screen.

[0060] The pressure regulating device controls the pipeline switching component through the processor, so that a negative pressure can be formed inside the pre-pressure cavity of the negative pressure generating component to meet the calibration requirements of the pressure regulating device during actual use.

[0061] As Figure 3 shown, the present invention also provides a pressure regulating method, including the following steps:

[0062] Step 1: The pressure control component controls the pressure generating component to generate a preset pressure according to the required air pressure, and inputs it into the supercharger and the preset pressure determination component respectively.

[0063] Specifically, after the pressure input part inputs the required pressure value into the processor, the processor controls the pressure generating component to generate a preset pressure. At the same time, the processor controls the working port b in the solenoid valve a to communicate with the working port a, the working port a in the solenoid valve e to communicate with the working port b, and the solenoid valves b6 and c7 are in the open state, and the solenoid valve g11 is in the closed state, so that the preset pressure generated by the pressure generating component is respectively input into the supercharger and the pre-pressure cavity through pipelines.

[0064] Step 2: When the pressure control component determines that the air pressure inside the preset pressure determination component is not less than the preset pressure, it controls the pressure generating component to stop the pressure generating work.

[0065] Specifically, the processor is electrically connected to the pressure sensor b. After the preset pressure generated by the pressure generating component is input into the interior of the pre-pressure cavity, the pressure sensor b collects the pressure electrical signal corresponding to the current preset pressure value in the pre-pressure cavity and inputs the collected pressure electrical signal into the processor, enabling the processor to process the current pressure value.

[0066] After receiving the pressure electrical signal, the processor analyzes it to obtain the corresponding preset pressure value. When the preset pressure value reaches the preset pressure value specified by the processor, the processor controls the pressure generating component to stop the pressure generating operation.

[0067] In addition, since the preset pressure is also input into the pre-pressure cavity, therefore, the preset pressure can be discharged outside the pressure regulating device through a pipeline as needed, and the preset pressure can also be input into the pressure output part through a pipeline.

[0068] Step 3: The supercharger boosts the preset pressure to form a boosted air pressure, which is input into the pressure output part through the set air pressure determination component to perform a calibration operation on the standard air pressure component and the air pressure component to be calibrated.

[0069] Specifically, the preset pressure is respectively input into the interior of the supercharger through pipelines. The supercharger performs a boosting operation on the preset pressure, and the boosted pressure is input into the positive pressure cavity at its output end through the solenoid valve b in the open state.

[0070] After the boosted pressure is input into the positive pressure cavity, the current pressure inside the positive pressure cavity is collected by the pressure sensor a to generate a pressure electrical signal corresponding to the current pressure, and the pressure electrical signal is input into the processor. The processor processes the pressure electrical signal and then inputs it into the display screen for display.

[0071] Among them, the pressure information can be in digital style or graphic style, etc.

[0072] Since the solenoid valve c is in the open state, therefore, the boosted pressure output from the positive pressure cavity can be input into the pressure output part through the solenoid valve c, thereby inputting the pressure into the standard pressure component and the pressure component to be calibrated assembled on the pressure output part, enabling the pointer or number in the standard pressure component and the pressure component to be calibrated to change according to the input pressure, and finally displaying the pressure information corresponding to the required pressure value.

[0073] In addition, the pressure control component also includes a pressure detection module. While the boosted pressure is being input into the pressure output part, a part of the pressure can also be input into the pressure control component, enabling this part of the pressure to contact the pressure detection module, so that the pressure electrical signal output from the solenoid valve c can be collected through the pressure detection module. After the processor processes the pressure electrical signal, the pressure value in this section of the pipeline and the pressure value input into the pressure output part can be obtained.

[0074] Among them, when inputting air pressure to the pressure output part and the pressure control component through the solenoid valve c, the processor can control the size of the valve body opening according to the pressure value collected by the pressure sensor a or the pressure value collected by the pressure detection module, so as to control the pressure storage amount in the positive pressure cavity or the pressure amount input to the pressure output part.

[0075] In addition, after the processor controls the pressure generating component to stop generating pressure, the pressure sensor a in the positive pressure cavity still continuously collects the pressure value in the positive pressure cavity and inputs the pressure electrical signal into the processor. After the processor processes the pressure electrical signal, if it determines that the current pressure value is less than the required pressure value, it controls the pressure generating component to start the pressure generating operation, the supercharger to start the supercharging operation, and controls the solenoid valve b to switch from the closed state to the open state, so as to input the supercharged air pressure into the positive pressure cavity and input pressure to the pressure output part. If it determines that the current pressure value is not less than the required pressure value, it continues to perform the calibration operation on the pressure component to be calibrated until the calibration is completed.

[0076] After completing the calibration operation on the pressure component to be calibrated, the processor can control the solenoid valve d8 to switch from the closed state to the open state, so as to discharge the remaining pressure stored in the positive pressure cavity or the remaining pressure stored in the pipeline to the outside of the pressure regulating device. In addition, the solenoid valve d can also remain in the closed state to store the remaining pressure in the positive pressure cavity and the pipeline.

[0077] In this embodiment, the standard pressure component and the pressure component to be calibrated are a standard pressure gauge and a pressure gauge to be calibrated respectively.

[0078] The above is only a preferred embodiment of the present invention, which is illustrative rather than restrictive to the invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the invention, but all will fall within the protection scope of the present invention.
