[0035] Figure 2 The diagram is a schematic diagram showing an example of the relationship between temperature and pressure changes in the pipe to be tested.

[0036] Figure 3 The present invention is a flow chart showing a method for controlling a high-temperature bursting pressure of a pipe according to an exemplary embodiment. DETAILED DESCRIPTION

[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Figure 1 FIG. 1 is a block diagram of a pipe high temperature bursting pressure control system according to an exemplary embodiment. Figure 1As shown, the pipe high temperature bursting pressure control system may include: a high temperature device 6, a cooling device 5; a hydraulic pressure device 1, a pressure sensor 2, a temperature sensor (not shown in the figure) and a control device 3;

[0039] The high temperature device 6 is used to heat the pipe 7 to be tested; the temperature sensor is connected to the high temperature device 6 to measure the temperature of the high temperature device 6; the cooling device 5 is connected to the high temperature device 6 to cool the liquid flowing out of the pipe 7 to be tested; the hydraulic pressure device 1 is connected to the cooling device 5 to adjust the hydraulic pressure in the pipe 7 to be tested; the pressure sensor 2 is connected to the hydraulic pressure device 1 to detect the pressure value of the liquid in the pipe 7 to be tested; the control device 3 is connected to the pressure sensor 2 and the temperature sensor respectively, and the control device 3 obtains the pressure value from the pressure sensor 2 and the temperature value from the temperature sensor; the control device 3 is also connected to the hydraulic pressure device 1, and when it is determined that the obtained temperature value does not reach the preset temperature value and the obtained pressure value does not meet the preset conditions, the control device 3 controls the hydraulic pressure device 1 to adjust the hydraulic pressure in the pipe 7 to be tested until the pressure value obtained by the control device 3 meets the preset conditions.

[0040] Generally speaking, in a high-temperature burst test, it is necessary to make the pipe to be tested burst in a high-temperature environment, thereby measuring the burst pressure of the pipe to be tested at different temperatures. During the high-temperature burst test, it is usually necessary to first fill the pipe to be tested with water and exhaust it at room temperature to ensure that there is no gas in the entire pressure circuit to avoid the harm caused by gas explosion. In related technologies, as the temperature increases, the pressure of the liquid in the pipe to be tested also increases. Usually, when the preset temperature value (for example, 350°C) is not reached, the pipe to be tested will burst due to excessive internal hydraulic pressure, resulting in test failure. Figure 2 This is a schematic diagram showing the relationship between temperature and pressure change in the pipe to be tested. Figure 2 As shown in the figure, when the temperature rises to 175°C, the internal pressure caused by temperature changes in the pipe to be tested can reach 100MPa (megapascal). In addition, the circuits of the high-temperature blasting systems in the related technologies are all in a high-temperature environment, which places high demands on sealing components and control components, and the auxiliary test facilities are complex, making the test control difficult and the test risk high.

[0041] As an example of this embodiment, the high temperature device 6 can be used to heat the pipe to be tested 7. For example, the high temperature device 6 can heat the pipe to be tested 7 from room temperature to 1000°C (degrees Celsius). The high temperature device 6 can be provided with an interface for connecting the pipe to be tested 7, which can be connected to an external pipeline. The pipe to be tested 7 can be installed on the interface, and a liquid (such as water) can be injected into the pipe to be tested 7 through an external pipeline. The interface of the high temperature device 6 can be connected to the cooling device 5 through a pipeline, and the cooling device 5 can cool the liquid output from the pipe to be tested 7. For example, the cooling device 5 can cool the liquid output from the pipe to be tested 7 to room temperature. The cooling device 5 can be a partition cooler, a spray cooler, a jacket cooler, etc. The embodiment of the present disclosure does not limit the type of the cooling device 5.

[0042] The temperature sensor may be connected to the high temperature device 6 and may measure the temperature of the high temperature device 6. The temperature sensor may be a resistance thermometer, a glass liquid thermometer or a pressure thermometer, and the embodiment of the present disclosure does not limit the type of the temperature sensor.

[0043] The hydraulic pressure device 1 can be connected to the cooling device 5, and the hydraulic pressure device 1 can adjust the hydraulic pressure in the pipe to be tested 7 (wherein, the hydraulic pressure device 1 can be, for example, a booster cylinder, and the hydraulic pressure in the pipe high-temperature bursting pressure control system circuit including the pipe to be tested 7 can be increased or decreased by moving the piston of the booster cylinder. It should be noted that other types of hydraulic pressure devices 1 such as turbine hydraulic pumps, etc. can also be selected, and the embodiment of the present disclosure does not limit the type of the hydraulic pressure device 1).

[0044] The pressure sensor 2 can be connected to the hydraulic pressure device 1, and the pressure sensor 2 can detect the pressure value of the liquid in the pipe 7 to be tested. For example, the pressure sensor 2 can use the pressure value detected in the hydraulic pressure device 1 as the pressure value of the liquid in the entire high-temperature bursting pressure control system pipeline loop including the pipe 7 to be tested.

[0045] The control device 3 can be connected to the pressure sensor 2 and the temperature sensor respectively, and the control device 3 can obtain the pressure value from the pressure sensor 2 and the temperature value from the temperature sensor. The control device can be, for example, a microcontroller unit (MCU), a central processing unit (CPU), etc., and the embodiment of the present disclosure does not limit the type of the control device.

[0046] The control device 3 can also be connected to the hydraulic pressure device 1, and the control device 3 can send a driving instruction to the hydraulic pressure device 1, so that the hydraulic pressure device 1 adjusts the hydraulic pressure in the pipe 7 to be tested according to the driving instruction. The control device 3 can pre-store a preset temperature (for example, the preset temperature can be one or more temperature thresholds) and a preset condition for pressure (for example, the preset condition can be a pressure value interval, or one or more pressure thresholds, and the embodiment of the present disclosure does not limit the specific form of the preset condition).

[0047] The control device 3 can determine the magnitude relationship between the obtained temperature value and the preset temperature value, and can determine whether the obtained pressure value meets the preset conditions. When it is determined that the obtained temperature value does not reach the preset temperature value and the obtained pressure value does not meet the preset conditions, the control device 3 can control the hydraulic pressure device 1 to adjust the hydraulic pressure in the pipe to be tested 7 until the pressure value obtained by the control device 3 meets the preset conditions. For example, if the preset temperature value is 350°C, the preset condition is that the pressure value is less than 80MPa, the current temperature value obtained is 100°C, and the current pressure value is 90 MPa, the control device can control the hydraulic pressure device to reduce the hydraulic pressure in the pipe to be tested until the pressure value obtained by the control device is 80 MPa. For another example, if the preset temperature value is 350°C, the preset condition is that the pressure value is less than 80MPa, the current temperature value obtained is 100°C, and the current pressure value is 60 MPa, the control device can control the hydraulic pressure device to increase the hydraulic pressure in the pipe to be tested until the pressure value obtained by the control device is 80 MPa.

[0048] The control device 3 can control the hydraulic pressure device 1 to increase the hydraulic pressure in the pipe material 7 to be tested, when it is determined that the acquired temperature value reaches the preset temperature value, until the pipe material 7 to be tested is detected to be broken (wherein, the control device 3 can determine whether the change of the pressure value acquired within the target period exceeds the preset change threshold value. If the control device 3 determines that the change of the pressure value acquired within the target period exceeds the change threshold value, the control device 3 can determine that the pipe material 7 to be tested is broken). When determining that the pipe material 7 to be tested is broken, the control device 3 can record the acquired pressure value and the acquired temperature value as the temperature and pressure when the pipe material 7 to be tested is broken.

[0049] The embodiment of the present disclosure utilizes a cooling device to cool the temperature of the liquid output by the high-temperature device, and limits the high temperature to a local circuit of the high-temperature bursting pressure control system of the pipe, so that normal-temperature instruments such as the control device and the pressure sensor can operate in a relatively low-temperature environment, thereby enabling the use of normal-temperature instruments with relatively high accuracy and relatively low cost to control and detect the high-temperature bursting test, thereby improving the measurement accuracy of the test data. In addition, the embodiment of the present disclosure can automatically balance the hydraulic pressure in the pipe to be tested during the heating process, effectively reducing the probability of failure of the pipe due to the increase in the heating pressure during the heating process, and effectively avoiding the probability of high-temperature vaporization of the liquid by presetting a certain pressure.

[0050] In one possible implementation, Figure 1 As shown, the pipe high temperature bursting pressure control system may include multiple cooling devices 5 and multiple pressure control devices 4, and the high temperature device 6 can heat multiple pipes to be tested 7, wherein the high temperature device 6 may have multiple interfaces for connecting the pipes to be tested 7; each interface may be connected to a cooling device 5 through a pipeline, and each cooling device 5 may be connected to a pressure control device 4. Multiple pressure control devices 4 may be connected to the control device respectively. The control device may control the hydraulic pressure device and part or all of the pressure control devices 4 respectively to adjust the hydraulic pressure in the pipes to be tested 7.

[0051] For example, when the control device determines that the obtained temperature value does not reach the preset temperature value and the obtained pressure value does not meet the preset conditions, it can simultaneously control the hydraulic pressure device and all pressure control devices 4 to adjust the hydraulic pressure in the pipe 7 to be tested until the pressure value obtained by the control device meets the preset conditions.

[0052] For another example, when the control device determines that the acquired temperature value does not reach the preset temperature value and the acquired pressure value does not meet the preset conditions, the control device may first control the hydraulic pressure system to adjust the hydraulic pressure in the pipe to be tested 7; if the control device controls the hydraulic pressure device to adjust the hydraulic pressure in the pipe to be tested 7 and determines that the acquired real-time pressure value still does not meet the preset conditions, the control device may control part or all of the pressure control devices 4 to adjust the hydraulic pressure in the pipe to be tested 7 until the pressure value acquired by the control device meets the preset conditions.

[0053] In a possible implementation, each pressure control device 4 may include an electromagnetic valve 41 and an air control valve 42 connected to each other, each air control valve 42 is connected to a cooling device 5, and each electromagnetic valve 41 is connected to a control device. The control device may control the degree of opening and closing of the air control valve 42 through the electromagnetic valve 41, thereby controlling the flow rate of the air control valve 42 to release the high-pressure liquid to reduce the hydraulic pressure in the pipe 7 to be tested. It should be noted that the pressure control device 4 may also be, for example, a booster cylinder, and the embodiment of the present disclosure does not limit the type of the pressure control device 4.

[0054] In a possible implementation, the high temperature device may include a protective device, which can isolate the pipes to be tested from each other to prevent the broken pipes to be tested from affecting the unbroken pipes to be tested, thereby further ensuring the safety and accuracy of the test. For example, the protective device may be a porous protective tube, each protective tube cover being buckled on the outside of a pipe to be tested. The protective device may also be, for example, a protective net, etc. The specific form of the protective device is not limited in the embodiments of the present disclosure.

[0055] In a possible implementation, the hydraulic pressure device may include a first pressure device and a second pressure device, wherein the pressure value adjusted by the first pressure device may be lower than the pressure value adjusted by the second pressure device, and the control device may control the first pressure device to adjust the hydraulic pressure in the pipe to be tested when it is judged that the obtained pressure value is greater than or greater than or equal to the preset pressure value, and the control device may control the second pressure device to adjust the hydraulic pressure in the pipe to be tested when it is judged that the obtained pressure value is less than or less than or equal to the preset pressure value. Thus, the pressure is more stably controlled, which is conducive to effectively measuring the bursting pressure of the pipe.

[0056] Application Examples

[0057] An explosion-proof structure can be set inside the high-temperature device shell to increase the safety of the test. The heating temperature of the high-temperature device can reach 1000℃, the heating rate can reach up to 30℃ / min, and the temperature measurement accuracy of the temperature sensor can be: 0.5%. The high-temperature device can carry out high-temperature explosion tests on 6 test pieces at the same time.

[0058] The hydraulic pressure device may be a pneumatic booster pump, and the control device may control the operating frequency of the pneumatic booster pump by controlling the air intake of the air source of the pneumatic booster pump, thereby controlling the output flow of the system.

[0059] The pneumatic booster pump can use a high-pressure and low-pressure parallel dual pump. When the pressure is low, the low-pressure pump is used to boost the pressure, and when the pressure is high, the high-pressure pump is used to boost the pressure.

[0060] During the high temperature test, the pipe to be tested can be filled with water first, and then vented at room temperature to ensure that there is no gas in the entire pressure circuit to avoid the harm caused by gas explosion.

[0061] During the heating process (i.e., when the temperature has not yet reached the preset temperature), the control device can control the boosting cylinder of the pneumatic booster pump to retreat or advance to adjust the volume of the liquid in the pipeline and the pipe to be tested according to the preset pressure value, so that the pipeline pressure is maintained at the preset pressure. For example, after the pre-charging and exhausting are completed, the control device can move the boosting cylinder piston to the position corresponding to the maximum pressure, so that when the temperature rises and the pressure rises, the piston moves to the position corresponding to the minimum pressure to reduce the pressure. If the piston moves to the position corresponding to the minimum pressure, the pressure still needs to be reduced. The control device can open the air control valve corresponding to each solenoid valve to release part of the high-pressure liquid in the pipeline loop for pressure relief. At the same time, the control device can control the boosting cylinder piston to move to the position corresponding to the maximum pressure, close the air control valve through the solenoid valve, and then continue to use the boosting cylinder to adjust the pressure until the pressure value obtained by the control device is maintained at the preset pressure value.

[0062] Figure 3 is a flow chart showing a method for controlling a high temperature bursting pressure of a pipe according to an exemplary embodiment. The method can be applied to the above-mentioned high temperature bursting pressure control system of the pipe, such as Figure 3 As shown, the method may include:

[0063] Step 300, the control device obtains a pressure value from the pressure sensor and obtains a temperature value from the temperature sensor;

[0064] Step 301, when the control device determines that the acquired temperature value does not reach the preset temperature value and the acquired pressure value does not meet the preset conditions, the control device controls the hydraulic pressure device to adjust the hydraulic pressure in the pipe to be tested until the pressure value acquired by the control device meets the preset conditions.

[0065] In a possible implementation, when the control device determines that the acquired temperature value reaches a preset temperature value, the control device controls the hydraulic pressure device to increase the hydraulic pressure in the pipe to be tested until a rupture of the pipe to be tested is detected.

[0066] In a possible implementation, the pipe high temperature bursting pressure control system further includes a plurality of pressure control devices, and the method further includes:

[0067] When the control device determines that the acquired temperature value does not reach the preset temperature value and the acquired pressure value does not meet the preset conditions, the control device controls the hydraulic pressure device and / or part or all of the pressure control devices to adjust the hydraulic pressure in the pipe to be tested until the pressure value acquired by the control device meets the preset conditions.

[0068] In one possible implementation, when the control device determines that the acquired temperature value does not reach the preset temperature value and the acquired pressure value does not meet the preset conditions, if the control device controls the hydraulic pressure device to adjust the hydraulic pressure in the pipe to be tested, and the pressure value acquired by the control device still does not meet the preset conditions, the control device controls part or all of the pressure control devices to adjust the hydraulic pressure in the pipe to be tested until the pressure value acquired by the control device meets the preset conditions.

[0069] In one possible implementation, the hydraulic pressure device includes a first pressure device and a second pressure device. When the control device determines that the acquired pressure value is greater than or greater than or equal to a preset pressure value, the control device controls the first pressure device to adjust the hydraulic pressure in the pipe to be tested. When the control device determines that the acquired pressure value is less than or less than or equal to the preset pressure value, the control device controls the second pressure device to adjust the hydraulic pressure in the pipe to be tested.

[0070] The above method has been described in the above description of the material high temperature explosion pressure control system, and will not be repeated here.

[0071] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
