Description

Technical Field

[0001] The invention relates to the technical field of isolation pipe valve control, and in particular to a control system of an isolation pipe valve of a pre-coded uniquely identified switch control isolation sleeve. Background Art

[0002] In the industrial production process, the control system of the isolation sleeve isolation pipe valve is used to control the flow and blockage of the fluid. It can open or close the pipeline when needed to achieve precise control of the fluid to meet the requirements of the production process. For example, in the chemical, oil and gas industries, the control system can be used to control the flow, pressure and temperature of the pipeline to ensure the stability and safe operation of the process. The control of the traditional isolation sleeve is usually electrical control, but this method usually has the problem of inaccurate analysis of pipeline pressure and inaccurate control of the isolation sleeve switch, resulting in incorrect opening and closing of the isolation sleeve, causing pipeline leakage or reducing industrial efficiency.

[0003] Chinese patent application publication number: CN114251464A discloses a low-temperature regulating valve for isolating pipelines, which includes a valve body assembly, wherein a valve seat is provided at a throttling hole inside a valve cavity of the valve body assembly, a valve core is arranged inside the valve body assembly and cooperates with the valve seat, a valve stem is connected to the valve core at the lower end, and the upper end passes through a bellows, a guide sleeve and an upper cover, a guide sleeve is provided at the upper end of the bellows, and is pressed by the upper cover into the inner hole at the upper end of the valve body assembly; a valve body connecting pipe, an isolating drip tray and a valve body upper flange are sequentially installed on the valve body, The upper end of the valve body is positioned and connected with the stopper at the lower end of the valve body connecting pipe, and the upper end of the valve body connecting pipe is positioned and connected with the stopper at the lower end of the valve body upper flange; the isolation drip plate is installed at the outer circle positioning stopper of the valve body connecting pipe and connected to prevent rainwater or condensation water from entering the isolation layer; the metal cone seal between the valve seat and the valve body assembly of the invention can achieve a leakage level of V or above; the valve core is threadedly connected to the valve stem, and the knurled pin is used to prevent loosening, which is convenient for disassembly; the bellows and packing are double sealed, with good sealing performance and high reliability.

[0004] It can be seen that the existing technology has the problem of not being precise enough in controlling the working process of the isolation sleeve and failing to promptly discover problems arising during the working process of the isolation sleeve and make timely adjustments, which may lead to pipeline medium leakage or reduce industrial efficiency and thus waste water resources. Summary of the invention

[0005] To this end, the present invention provides a control system for a pre-coded uniquely identified switch-controlled isolation sleeve isolation pipe valve, so as to overcome the problems in the prior art of inaccurate control of the isolation sleeve working process and failure to promptly detect problems arising during the isolation sleeve working process and make timely adjustments, resulting in pipeline medium leakage or reduced industrial efficiency and thus waste of water resources.

[0006] To achieve the above object, the present invention provides a control system for a switch-controlled isolation sleeve isolation pipe valve with pre-coded unique identification, comprising:

[0007] A switch sleeve moving module, comprising a first small hole penetrating inside the upper joint of the isolation sleeve isolation pipe valve for controlling the medium to flow into the first cavity, a second small hole arranged inside the front end of the main body and connected to the main body for controlling the medium to flow out of the first cavity, a first cavity arranged at the upper end of the tail of the upper joint and connected to the upper joint, a switch sleeve arranged at the tail of the first cavity and connected to the first cavity for controlling the switch of the isolation sleeve, a second cavity arranged at the rear of the switch sleeve and connected to the switch sleeve, a third small hole arranged inside the switch sleeve and connected to the switch sleeve for controlling the medium to flow into the second cavity, a fourth small hole arranged inside the middle end of the main body and connected to the main body for controlling the medium to flow out of the second cavity, a valve seat arranged above the switch sleeve and connected to the switch sleeve for carrying a pin shaft, a reset spring arranged at the center of the switch shaft and connected to the pin shaft for resetting the switch sleeve, and a valve plate arranged below the reset spring and connected to the reset spring for closing the sleeve;

[0008] The control module includes a first control module disposed between the first small hole and the second small hole and connected to the upper joint for controlling the opening and closing of the first small hole and the second small hole according to the pre-programmed pressure code, and a second control module disposed between the third small hole and the fourth small hole and connected to the switch sleeve for controlling the opening and closing of the third small hole and the fourth small hole according to the pre-programmed pressure code. The control module also includes:

[0009] A data analysis unit, which is used to obtain the isolation sleeve opening and closing conversion time and determine whether to issue an early warning according to the comparison result of the isolation sleeve opening and closing conversion time with the preset conversion time, including a working parameter adjustment early warning and a cleaning adjustment early warning;

[0010] An adjustment unit is connected to the data analysis unit and is used to determine the adjustment amount of the isolation sleeve working parameters based on the comparison result of the frequency in which the isolation sleeve opening and closing conversion time is greater than the first preset conversion time and the first preset frequency within the cycle, and is also used to determine the adjustment amount of the isolation sleeve cleaning parameters based on the comparison result of the frequency in which the isolation sleeve opening and closing conversion time is greater than the second preset conversion time and the second preset frequency within the cycle.

[0011] Furthermore, the pre-coded pressure code includes a first pre-coded pressure code for controlling the displacement of the switch sleeve in a first direction and a second pre-coded pressure code for controlling the displacement of the switch sleeve in a second direction, and the control module determines the opening and closing of the small hole according to the identified pre-coded pressure code, wherein:

[0012] According to the first pre-coded pressure code, the first small hole is controlled to be opened, the second small hole is controlled to be closed, and the third small hole is controlled to be closed, and the fourth small hole is controlled to be opened;

[0013] According to the second pre-coded pressure code, the first small hole is controlled to be closed and the second small hole is controlled to be opened, and the third small hole is controlled to be opened and the fourth small hole is controlled to be closed.

[0014] Furthermore, the pre-coded pressure code is determined according to the maximum bearing pressure in the pipeline and the average bearing pressure in the pipeline.

[0015] Further, the data analysis unit issues the working parameter adjustment warning under the condition that the isolation sleeve opening and closing conversion time is greater than the first preset conversion time and less than or equal to the second preset conversion time, and issues the cleaning adjustment warning under the condition that the isolation sleeve opening and closing conversion time is greater than the second preset conversion time;

[0016] Wherein, the first preset conversion time is shorter than the second preset conversion time.

[0017] Furthermore, under the condition of the working parameter adjustment warning, the adjustment unit determines the adjustment amount of the isolation sleeve working parameters according to the comparison result of the isolation sleeve opening and closing conversion time within the cycle and the first preset frequency, wherein the isolation sleeve working parameters include the pressure and flow of the injected medium.

[0018] Furthermore, the first preset conversion time and the second preset conversion time are determined according to the historical average value of the opening and closing conversion time of the isolation sleeve.

[0019] Furthermore, the adjustment amount of the pressure or flow rate of the injected medium is negatively correlated with the frequency of the isolation sleeve opening and closing switching time being greater than the first preset switching time within the cycle.

[0020] Furthermore, under the condition of the cleaning adjustment warning, the adjustment unit determines the adjustment amount of the isolation sleeve cleaning parameters according to the comparison result of the frequency in which the isolation sleeve opening and closing conversion time within the cycle is greater than the second preset conversion time and the second preset frequency, wherein the isolation sleeve cleaning parameters include the cavity cleaning cycle and the small hole cleaning cycle.

[0021] Furthermore, the adjustment amount of the cavity cleaning cycle and the small hole cleaning cycle is negatively correlated with the frequency of the isolation sleeve opening and closing switching time being greater than the second preset switching time within the cycle.

[0022] Furthermore, the isolation sleeve also includes a supporting module, which includes a main body arranged at the top for supporting the isolation sleeve, an upper joint arranged at the front end below the main body and connected to the main body for connecting to the valve outlet, and a lower joint arranged at the rear end below the main body and connected to the main body for connecting to the valve inlet.

[0023] Compared with the prior art, the beneficial effect of the present invention is that the present invention can standardize and unify the opening and closing operations of the isolation sleeve by means of pre-coded pressure codes. The operator only needs to operate according to the preset pre-coded pressure code without complicated judgment and adjustment. The operation process can be simplified, the probability of human error can be reduced, and the consistency and reliability of the operation can be improved. By following the preset pre-coded pressure code for opening and closing operations, it can be ensured that the operation is performed within a safe range, avoiding exceeding the bearing capacity of the pipeline system, reducing the risk of accidents and leakage, and improving the safety of the workplace. By determining the opening and closing of the isolation sleeve by means of pre-coded pressure codes, the decision-making time and adjustment process of the operator can be reduced. The preset code can control the pressure and flow of the fluid to prevent damage to the equipment caused by excessive or low pressure. By improving the accuracy of controlling the flow of the fluid, the effect of saving water resources can be achieved.

[0024] Furthermore, by comparing the actual opening and closing conversion time of the isolation sleeve with the preset conversion time T, the data analysis unit of the present invention can monitor the operating status of the isolation sleeve in real time. If there is a significant deviation between the actual conversion time and the preset time, it may mean that there is an abnormality or failure in the isolation sleeve, and a cleaning adjustment warning will be issued. The warning system can provide timely warnings to help operation and maintenance personnel identify potential problems and take appropriate measures. If there is a slight deviation between the actual conversion time and the preset time, a working parameter adjustment warning will be issued. By analyzing the conversion time data, opportunities to improve the operation and maintenance process and optimize equipment performance can be identified, thereby improving production efficiency and system reliability to achieve the effect of saving resources.

[0025] The present invention determines whether adjustment is needed based on the comparison result of the frequency of the isolation sleeve opening and closing conversion time greater than the first preset conversion time within the cycle and the first preset frequency under the condition that it is determined that the data analysis unit issues a warning for adjustment of the working parameters. The isolation sleeve opening and closing conversion time that frequently exceeds the first preset frequency may indicate potential problems or failures. By monitoring this frequency deviation, abnormal behavior of the isolation sleeve can be discovered early and corresponding troubleshooting measures can be taken, which helps prevent more serious failures from occurring, reduce equipment downtime and maintenance costs, and adjusting the performance of the isolation sleeve can improve its operating efficiency and reliability.

[0026] Furthermore, the present invention evaluates the working state of the isolation sleeve by comparing the frequency of the isolation sleeve opening and closing conversion time and the second preset conversion time within the cycle, and adjusts the adjustment amount of the cavity cleaning cycle and the small hole cleaning cycle according to the evaluation result. Specifically, if the frequency is greater than the second preset frequency, it means that the isolation sleeve opening and closing conversion time is long, there may be blockage or other problems, and the cleaning cycle needs to be increased to ensure normal operation. Conversely, if the frequency is less than the second preset frequency, it may indicate that the isolation sleeve is faulty and needs to be replaced. In this way, the cleaning cycle can be flexibly adjusted according to the actual working conditions of the isolation sleeve, improving the reliability and performance of the equipment, while avoiding unnecessary cleaning operations.

[0027] Furthermore, the present invention evaluates the working state of the isolation sleeve by comparing the frequency of the isolation sleeve opening and closing conversion time and the second preset conversion time within the cycle, and adjusts the adjustment amount of the cavity cleaning cycle and the small hole cleaning cycle according to the evaluation result. Specifically, if the frequency is greater than the second preset frequency, it means that the isolation sleeve opening and closing conversion time is long, there may be blockage or other problems, and the cleaning cycle needs to be increased to ensure normal operation. Conversely, if the frequency is less than the second preset frequency, it may indicate that the isolation sleeve is faulty and needs to be replaced. In this way, the cleaning cycle can be flexibly adjusted according to the actual working conditions of the isolation sleeve, improving the reliability and performance of the equipment, while avoiding unnecessary cleaning operations.

[0028] Furthermore, the present invention can evaluate the accuracy of the early warning system by comparing the actual early warning efficiency of the isolation sleeve with the preset early warning efficiency. If there is a significant deviation between the actual early warning efficiency and the preset value, it may mean that the early warning system has a false alarm problem. By evaluating the accuracy, potential problems in the early warning system can be identified and corrected to improve the reliability and accuracy of the early warning. By comparing the early warning efficiency, bottlenecks and improvement points in the early warning system can be identified to improve the efficiency and timeliness of the early warning response and ensure that abnormal situations are handled and controlled in a timely manner. According to the comparison results of the early warning efficiency, it can be determined whether the control process of the isolation sleeve needs to be optimized. By optimizing the control process, the performance and reliability of the early warning system can be improved, the situation of missed reports can be reduced, and the operation management level of the isolation sleeve can be improved.

[0038] The control system of the switch control isolation sleeve isolation pipe valve pre-coded and uniquely identified in the embodiment of the present invention includes:

[0041] The control module includes a first control module 15 disposed between the first small hole and the second small hole and connected to the upper joint for controlling the opening and closing of the first small hole and the second small hole according to the pre-programmed pressure code, and a second control module 16 disposed between the third small hole and the fourth small hole and connected to the switch sleeve for controlling the opening and closing of the third small hole and the fourth small hole according to the pre-programmed pressure code. The control module also includes:

[0042] A data analysis unit, which is used to obtain the isolation sleeve opening and closing conversion time and determine whether to issue an early warning according to the comparison result of the isolation sleeve opening and closing conversion time with the preset conversion time, including a working parameter adjustment early warning and a cleaning adjustment early warning;

[0043] An adjustment unit connected to the data analysis unit, for determining an adjustment amount for the isolation sleeve working parameter according to a comparison result of the frequency in which the isolation sleeve opening and closing conversion time is greater than the first preset conversion time and the first preset frequency within the cycle, and for determining an adjustment amount for the isolation sleeve cleaning parameter according to a comparison result of the frequency in which the isolation sleeve opening and closing conversion time is greater than the second preset conversion time and the second preset frequency within the cycle;

[0044] An optimization unit, connected to the adjustment unit, for determining whether to optimize the control parameters of the isolation sleeve according to the early warning efficiency of the isolation sleeve;

[0045] Among them, the pre-coded pressure code includes a first pre-coded pressure code for controlling the displacement of the switch sleeve in a first direction and a second pre-coded pressure code for controlling the displacement of the switch sleeve in a second direction, and the preset conversion time includes a first preset conversion time and a second conversion time, and the first preset conversion time is less than the second preset conversion time.

[0046] In the embodiment of the present invention, a pressure sensor can be installed at the front end of the isolation sleeve to detect the pressure in the pipeline. The microcontroller inside the control module processes the numerical value of the pressure sensor to generate a corresponding pre-coded pressure code, and the control module controls the opening and closing of the small hole according to the pre-coded pressure code.

[0047] Specifically, the control module determines the opening and closing of the small hole according to the identified pre-coded pressure code;

[0048] If the pre-coded pressure code identified by the first control module is the first pre-coded pressure code, the first control module determines to control the first small hole to be opened and the second small hole to be closed;

[0049] If the pre-coded pressure code identified by the second control module is the first pre-coded pressure code, the second control module determines to control the third small hole to be closed and the fourth small hole to be opened;

[0050] If the pre-coded pressure code identified by the first control module is the second pre-coded pressure code, the first control module determines to control the first small hole to be closed and the second small hole to be opened;

[0051] If the pre-coded pressure code identified by the second control module is the second pre-coded pressure code, the second control module determines to control the third small hole to be opened and the fourth small hole to be closed.

[0052] In the embodiment of the present invention, the first pre-coded pressure code includes generating a first pre-coded pressure code when the pressure in the pipeline is in the range of 0.8 times to 1.2 times the average withstand pressure, and the second pre-coded pressure code includes generating a second pre-coded pressure code when the pressure in the pipeline is in the range of 1.2 times to 0.8 times the maximum withstand pressure in the pipeline, but the above values ​​are not limited to this, and technicians in this field can also adjust the values ​​according to actual needs.

[0053] The present invention can standardize and unify the opening and closing operations of the isolation sleeve by pre-coding the pressure code. The operator only needs to operate according to the preset pre-coded pressure code without complicated judgment and adjustment. The operation process can be simplified, the probability of human error can be reduced, and the consistency and reliability of the operation can be improved. By following the preset pre-coded pressure code for opening and closing operations, it can be ensured that the operation is performed within a safe range, avoiding exceeding the bearing capacity of the pipeline system, reducing the risk of accidents and leakage, and improving the safety of the workplace. By determining the opening and closing of the isolation sleeve by pre-coding the pressure code, the decision-making time and adjustment process of the operator can be reduced. The preset code can control the pressure and flow of the fluid to prevent damage to the equipment caused by excessive or low pressure, and at the same time protect the pipeline system from overload and overpressure. By improving the accuracy of controlling the flow of the fluid, the effect of saving water resources can be achieved.

[0054] Specifically, the data analysis unit determines whether to issue an early warning based on the comparison result of the isolation sleeve opening and closing switching time T and the preset switching time Ti0;

[0055] If T≤T10, the data analysis unit determines not to issue an early warning;

[0056] If T10<T≤T20, the data analysis unit determines to issue a warning for adjusting the working parameters;

[0057] If T>T20, the data analysis unit determines to issue a cleaning adjustment warning;

[0058] Among them, i=1,2, the value of the first preset conversion time T10 is the historical average value of the opening and closing conversion time of the isolation sleeve, and the value of the second preset conversion time T20 is 1.3 times the historical average value of the opening and closing conversion time of the isolation sleeve, but the above values ​​are not limited to this, and technical personnel in this field can also adjust the values ​​according to actual needs.

[0059] The conversion time described in the embodiment of the present invention is determined according to the time from when the medium flow rate of the first small hole among the four small holes increases from zero to when the medium flow rate of the last small hole increases to the maximum medium flow rate, or the change time from when the medium flow rate of the first small hole is the maximum medium flow rate and then decreases to when the medium flow rate of the last small hole is zero. For example, when the time when the medium flow rate of the first small hole increases from zero is 3:54:15 seconds, and the time when the medium flow rate of the last small hole increases to the maximum medium flow rate is 3:55:01 seconds, the conversion time is 46 seconds. When the time when the medium flow rate of the first small hole decreases from the maximum medium flow rate is 5:34:25 seconds, and the time when the medium flow rate of the last small hole increases to the maximum medium flow rate is 5:35:18 seconds, the conversion time is 53 seconds.

[0060] By comparing the actual opening and closing conversion time of the isolation sleeve with the preset conversion time T, the data analysis unit of the present invention can monitor the operating status of the isolation sleeve in real time. If there is a significant deviation between the actual conversion time and the preset time, it may mean that there is an abnormality or failure in the isolation sleeve, and a cleaning adjustment warning will be issued. The warning system can provide timely warnings to help operation and maintenance personnel identify potential problems and take appropriate measures. If there is a slight deviation between the actual conversion time and the preset time, a working parameter adjustment warning will be issued. By analyzing the conversion time data, opportunities to improve the operation and maintenance process and optimize equipment performance can be identified, thereby improving production efficiency and system reliability to achieve the effect of saving resources.

[0061] Specifically, under the condition that the data analysis unit determines to issue a warning for adjusting the working parameters, the adjustment unit determines to adjust the working parameters of the isolation sleeve according to the comparison result of the frequency S in which the isolation sleeve opening and closing conversion time is greater than the first preset conversion time within the cycle and the first preset frequency S0;

[0062] If S≥S0, the adjustment unit determines that the working parameters of the isolation sleeve need to be adjusted;

[0063] If S<S0, the adjustment unit determines that there is no need to adjust the working parameters of the isolation sleeve;

[0064] The value range of the first preset frequency S0 is set to 0-0.3, and the value of the first preset frequency S0 is preferably 0.2, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0065] In the embodiment of the present invention, the frequency of the isolation sleeve opening and closing conversion time being greater than the first preset conversion time within the cycle is the ratio of the number of times the isolation sleeve opening and closing conversion time is greater than the first preset conversion time within the cycle to the total number of detections. The cycle can be selected as 30 days, and the isolation sleeve working parameters include the pressure and flow rate of the injected medium.

[0066] Specifically, under the condition that the adjustment unit determines that the working parameters of the isolation sleeve need to be adjusted, the adjustment unit determines to adjust the pressure W1 of the injected medium and the flow rate W2 of the injected medium by a first adjustment coefficient K1, and the adjustment coefficient is calculated and set by the following formula:

[0067] ;

[0068] The adjusted pressure W1' of the injected medium is set to W1'=K1×W1;

[0069] The adjusted flow rate W2' of the injection medium is set to W2'=K1×W2.

[0070] The present invention determines whether adjustment is needed based on the comparison result of the frequency of the isolation sleeve opening and closing conversion time greater than the first preset conversion time within the cycle and the first preset frequency under the condition that it is determined that the data analysis unit issues a warning for adjustment of the working parameters. The isolation sleeve opening and closing conversion time that frequently exceeds the first preset frequency may indicate potential problems or failures. By monitoring this frequency deviation, abnormal behavior of the isolation sleeve can be discovered early and corresponding troubleshooting measures can be taken, which helps prevent more serious failures from occurring, reduce equipment downtime and maintenance costs, and adjusting the performance of the isolation sleeve can improve its operating efficiency and reliability.

[0071] Specifically, the data analysis unit determines the adjustment amount of the isolation sleeve cleaning parameter by comparing the frequency S of the isolation sleeve opening and closing switching time greater than the second preset switching time within the cycle with the second preset frequency S1 under the condition of determining that the cleaning adjustment warning is issued;

[0072] If S≥S1, the adjustment unit determines to adjust the cleaning parameters of the isolation sleeve with a second adjustment coefficient;

[0073] If S<S1, the adjustment unit determines to replace the isolation sleeve;

[0074] The value range of the second preset frequency S1 is set to 0-0.2, and the value of the second preset frequency is preferably 0.1, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0075] The isolation sleeve cleaning parameters in the embodiment of the present invention include a cavity cleaning cycle and a small hole cleaning cycle.

[0076] The present invention evaluates the working state of the isolation sleeve by comparing the frequency of the isolation sleeve opening and closing conversion time and the second preset conversion time within the cycle, and adjusts the adjustment amount of the cavity cleaning cycle and the small hole cleaning cycle according to the evaluation result. Specifically, if the frequency is greater than the second preset frequency, it means that the isolation sleeve opening and closing conversion time is long, there may be blockage or other problems, and the cleaning cycle needs to be increased to ensure normal operation. Conversely, if the frequency is less than the second preset frequency, it may indicate that the isolation sleeve is faulty and needs to be replaced. In this way, the cleaning cycle can be flexibly adjusted according to the actual working conditions of the isolation sleeve, improving the reliability and performance of the equipment, while avoiding unnecessary cleaning operations.

[0077] Specifically, the optimization unit determines whether to optimize the control parameters of the isolation sleeve according to the comparison result between the early warning efficiency M of the isolation sleeve and the preset early warning efficiency M0;

[0078] If M≥M0, the optimization unit determines not to optimize the isolation sleeve control parameters;

[0079] If M<M0, the optimization unit determines to optimize the control parameters of the isolation sleeve;

[0080] Among them, the value range of the preset warning efficiency M0 is set to 0.7-1, and the value of the preset warning efficiency is preferably 0.85, but the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0081] Specifically, under the condition that the control process of the isolation sleeve is optimized, the optimization unit determines to optimize the preset conversion time with an optimization coefficient F, and the optimization coefficient F is calculated and set by the following formula:

[0082] ;

[0083] The optimized preset conversion time is set to T10'=F×T10, T20'=F×T20.

[0084] The warning efficiency described in the embodiment of the present invention is the ratio of the number of effective warnings to the total number of warnings, and the warning effectiveness includes that when the data analysis unit issues a working parameter adjustment warning, the frequency of the isolation sleeve opening and closing conversion time within the period being greater than the first preset conversion time is greater than or equal to the first preset frequency, and when the data analysis unit issues a cleaning adjustment warning, the frequency of the isolation sleeve opening and closing conversion time being greater than the second preset conversion time is greater than or equal to the second preset frequency.

[0085] The present invention can evaluate the accuracy of the early warning system by comparing the actual early warning efficiency of the isolation sleeve with the preset early warning efficiency. If there is a significant deviation between the actual early warning efficiency and the preset value, it may mean that the early warning system has a false alarm problem. By evaluating the accuracy, potential problems in the early warning system can be identified and corrected to improve the reliability and accuracy of the early warning. By comparing the early warning efficiency, bottlenecks and improvement points in the early warning system can be identified to improve the efficiency and timeliness of the early warning response and ensure that abnormal situations are handled and controlled in a timely manner. According to the comparison result of the early warning efficiency, it can be determined whether the control process of the isolation sleeve needs to be optimized. By optimizing the control process, the performance and reliability of the early warning system can be improved, the situation of missed reports can be reduced, and the operation management level of the isolation sleeve can be improved.
