Description

[0002] Existing pipeline sealing test methods, such as the water pressure pipeline detection method, vacuum detection method, helium detection method, ultrasonic detection method, and infrared detection method, have certain limitations.

[0003] Specifically, in the water pressure pipeline detection method, a water pump is directly connected to the pipeline, and pressure is supplemented through the water pump. When the pressure reaches the detection value, the valve is immediately closed to maintain the pipeline pressure, and then observed for a certain period of time. The sealing performance of the pipeline is determined according to the pressure loss rate in the pipeline.

[0037] The present disclosure will be further described below by way of embodiments, but the present disclosure is not limited thereto within the scope of the described embodiments.

The use of ordinal numbers and other prefix words for distinguishing described objects in the embodiments of the present disclosure does not constitute a limitation on the described objects.

In addition, in the description of this embodiment, unless otherwise specified, the meaning of "a plurality" is two or more.

[0039] Embodiment 1

[0040] Figure 1 Schematic structural diagram of a pipeline sealing detection device provided for this embodiment. The pipeline sealing detection device 10 includes a water replenishing unit 11, a measurement unit 12, a voltage stabilizing unit 13, and a controller ( Figure 1 not shown).

[0041] The water outlet of the water replenishing unit 11 is connected to the water inlet of the target pipeline 14; the water replenishing unit 11 is connected to the measurement unit 12 through a bottom interface, and the air inlet of the measurement unit 12 is connected to the air outlet of the voltage stabilizing unit 13.

[0042] The controller is configured to, in response to both ends of the target pipeline being blocked, control the water replenishing unit to replenish water to the target pipeline and control the bottom interface to close; in the case where the target pipeline is in a full water state, control the pressure stabilizing unit to provide pressure to the measuring unit through the air outlet and control the bottom interface to open; in the case where the water level height in the measuring unit is stable within a preset range, detect the tightness of the target pipeline according to the water level height in the measuring unit. For example, when the water level height in the measuring unit is stable outside the preset range, the water volume in the water replenishing unit can be adjusted, such as by appropriately adding water to the water replenishing unit or discharging water from the water replenishing unit, so as to adjust the water level height until the water level height is stable within the preset range. Specifically, the tightness of the target pipeline is detected according to the change amount of the water level height in the measuring unit.

[0043] In this embodiment, the preset range is a height range set by the user. A short operation of replenishing (injecting) or discharging water to the water replenishing unit can easily make the water level height stable within the preset range, thereby avoiding the strict operations of replenishing or discharging water to the pipeline in conventional pipeline detection. In the prior art, since a very small amount of water injection or discharge can cause a large fluctuation in the pressure of the target pipeline, this operation needs to be extremely precise, and the operation difficulty is significantly increased. However, in the present disclosure, adjusting the water level height does not cause a change in the pressure inside the target pipeline. The present disclosure controls the pressure of the target pipeline through the adjustment of the pressure stabilizing unit. Therefore, if the pressure provided by the pressure stabilizing unit is fixed, the pressure of the target pipeline is also fixed, that is, constant pressure of the target pipeline is achieved.

[0044] In this embodiment, when both ends of the target pipeline are blocked, the bottom interface is closed, and the water replenishing unit replenishes water to the target pipeline; in the specific implementation process, the target pipeline can be cleaned and exhausted first, and then rapid water injection can be carried out to improve the detection accuracy. Specifically, the water replenishing unit can be a water tank. After being buffered by the water tank, water is injected into the target pipeline from the water outlet of the water tank to realize water injection into the target pipeline until the target pipeline is full of water, thereby providing a basic environmental condition for pipeline tightness detection.

[0045] In the case where the target pipeline is in a full water state, control the pressure stabilizing unit to provide pressure to the measuring unit through the air outlet, and the bottom interface is open; the pressure of the pipeline tightness detection device is increased by compressing air through the pressure stabilizing unit.

[0046] When the water level height in the measurement unit is stable within a preset range, the tightness of the target pipeline is detected according to the water level height in the measurement unit. Through the transition of the voltage stabilization unit, the present disclosure solves the defects in the prior art that directly supplying air to the target pipeline by an air compressor and closing the valve after the water pump boosts the pressure to the detection pressure are likely to cause damage to the target pipeline. At the same time, it also solves the problem that the target pipeline cannot maintain the pressure accurately and constantly at a certain value, and overcomes the problem of pressure fluctuation in the target pipeline during detection. Further, the operation and pressure adjustment of the water replenishing unit and the voltage stabilization unit enable the pipeline tightness testing device provided by the present disclosure to meet the market demand. Specifically, it is not easy to cause pipeline damage and secondary pollution, and there are also no problems of high cost and susceptibility to environmental interference.

[0047] In addition, the preset range can be the range of the measurement unit or other water level height ranges set by the user.

[0048] In an optional implementation manner, as Figure 2 shown, the pipeline tightness detection device further includes an air compressor 15, and the air compressor 15 is connected to the air inlet of the voltage stabilization unit 13.

[0049] The controller is further configured to control the operation of the air compressor when the maximum pressure provided by the voltage stabilization unit is less than the target pressure; wherein, the target pressure is determined according to the working pressure of the target pipeline. To perform the tightness detection of the target pipeline, generally, the target pressure can be set to 1.25 - 1.5 times the working pressure of the target pipeline, so as to achieve a better detection effect.

[0050] In this implementation manner, the function of the air compressor is to inject compressed air into the voltage stabilization unit to avoid the problem of air pressure drop in the voltage stabilization unit. Another function of the air compressor is to prevent the piston in the voltage stabilization unit from continuously moving downward when air leaks through the piston of the voltage stabilization unit or the water level in the measurement unit drops. At this time, the air compressor can input compressed air into the voltage stabilization unit to make the piston move upward to avoid touching the bottom.

[0051] In an optional implementation manner, the pipeline tightness detection device further includes a height sensor, and the height sensor is used to detect the water level height in the measurement unit and transmit the water level height to the controller. In this implementation manner, the height sensor timely transmits the read water level height to the controller to achieve accurate measurement of the pipeline tightness detection device.

[0052] In an optional implementation manner, as Figure 3As shown in the figure, the voltage stabilizing unit 13 includes a pressure assembly 131, a cylinder 132, a connecting rod 133, and a piston 134. The piston 134 is located inside the cylinder 132, and the piston 134 divides the cylinder 132 into a first space 1321 and a second space 1322. The cylinder 132 further includes a communication port 1323, and the communication port is provided in the second space. The communication port is used to connect the second space of the cylinder to the external atmospheric environment.

[0053] One end of the connecting rod is connected to the pressure assembly, and the other end of the connecting rod is connected to the piston; the pressure assembly is used to apply pressure to the first space of the cylinder; the air outlet of the voltage stabilizing unit is the air outlet of the cylinder, and the air inlet of the voltage stabilizing unit is the air inlet of the cylinder.

[0054] In this embodiment, by adjusting the pressure assembly, different pressure tests can be performed on the target pipeline. Among them, there is a gap between the piston and the cylinder to ensure that the piston will not be stuck due to excessive friction during movement. The communication port of the cylinder is used to promote gas flow to balance the air pressure in the second space. Specifically, when the piston moves downward under the action of the pressure assembly to compress air, the pressure in the first space increases, and the pressure is transmitted to the measuring unit and the water replenishing unit through the air outlet of the cylinder to realize the pressurization of the entire pipeline sealing detection device; when the first space of the cylinder is compressed to a certain extent, such as close to the bottom of the cylinder, the air compressor is controlled to supply air to the first space of the cylinder. At the same time, due to air leakage at the communication port, air flow, and the increase in the second space, the air in the cylinder decreases, so a negative pressure is easily formed in the second space. At this time, external air enters from the communication port to promote the subsequent compression of the gas, and implement pressure sending and pressure replenishment for voltage stabilization.

[0055] In an alternative embodiment, the pipeline sealing detection device further includes a pressure sensor, and the pressure sensor is used to detect the pressure in the target pipeline.

[0056] In a specific example, the stage in which the voltage stabilizing unit provides pressure to the measuring unit through the air outlet can be called the pipeline pressurization stage. In the initial stage of the pipeline pressurization stage, the voltage stabilizing unit can be directly used for pressurization, and only by adjusting the pressure assembly (such as the number of weights) to compress air for pressurization. When pressurized to a certain stage, the air in the piston cavity (i.e., the first space) is compressed to a very small volume. At this time, the piston is about to touch the bottom and subsequent measurement work cannot be carried out. By controlling the operation of the air compressor, the first space is supplemented with compressed air to lift the height of the piston to meet the measurement working conditions of the subsequent measuring unit.

[0057] In other specific embodiments, if the cylinder is not provided with a communication port, it is also possible to promote gas flow by providing a gap at the connection between the connecting rod and the upper edge of the cylinder, so as to achieve the same function as the communication port.

[0058] Specifically, the pressure assembly may include weights, and the controller adjusts the number of weights to achieve the adjustment of the air pressure in the cylinder by the pressure assembly, realizing the simple operation of the pipeline sealing test and reducing the complexity of the voltage stabilizing unit.

[0059] In an alternative embodiment, the controller is specifically configured to detect the sealing performance of the target pipeline according to the water level height that drops after a preset duration when the water level height in the measurement unit is stable within a preset range.

[0060] In this embodiment, the measurement unit may be a measuring tube, and the measuring tube has scales and a range. Through the synchronous pressure replenishment and balance adjustment of the water tank and the voltage stabilizing unit, the scale value of the measuring tube falls within the preset range; further, after voltage stabilization, the sealing performance of the target pipeline is judged according to the scale change value of the measuring tube after a preset duration.

[0061] Specifically, when the controller detects that the water level height in the measuring tube is stable at a certain value A within the preset range, the target pipeline is maintained stable at the target detection pressure for a certain period of time, such as 30 minutes, and then the water level height of the measuring tube is observed to have dropped by B compared to A. The sealing performance of the target pipeline is judged by the height change rate (B / A*100%). If the height change rate is greater than the threshold, the sealing performance detection of the target pipeline is unqualified; if the height change rate is less than or equal to the threshold, the sealing performance detection of the target pipeline is qualified.

[0062] In an alternative embodiment, the controller is further configured to adjust the water volume in the water replenishing unit when the water level height in the measurement unit exceeds the preset range. When the water level height in the measurement unit is stable outside the preset range, the water volume in the water replenishing unit can be adjusted, for example, by appropriately adding water to the water replenishing unit or draining water from the water replenishing unit, so as to adjust the water level height until the water level height is stable within the preset range.

[0063] Embodiment 2

[0064] Corresponding to the foregoing Embodiment 1 of the pipeline sealing performance detection device, the present disclosure also provides an embodiment of a pipeline sealing performance detection system.

[0065] As Figure 1 shown, the pipeline sealing performance detection system includes a target pipeline 14 and the pipeline sealing performance detection device 10 as described in Embodiment 1.

[0066] In an alternative embodiment, the pipeline sealing performance detection system further includes an exhaust valve ( Figure 1(not shown in the figure), the exhaust valve is arranged at the top of the target pipeline, and the controller in the pipeline sealing detection device is used to control the exhaust valve to open during the process of filling water into the target pipeline.

[0067] In this embodiment, an exhaust valve is arranged at the highest point of the target pipeline, and the exhaust valve is controlled to open during the process of filling water into the target pipeline, so that the air in the target pipeline can be discharged, making the pipeline sealing detection more accurate.

[0068] In an alternative embodiment, as Figure 4 shown, the pipeline sealing detection system further includes a water supply unit 16, and the output end of the water supply unit 16 is connected to the water inlet of the water replenishing unit 11 in the pipeline sealing detection device.

[0069] In this embodiment, when both ends of the target pipeline are blocked, the bottom interface is closed, and the water replenishing unit replenishes water to the target pipeline; when the target pipeline is in a full water state, the pressure stabilizing unit provides pressure to the measuring unit through the air outlet, and the bottom interface is opened. In a specific example, the stage in which the pressure stabilizing unit provides pressure to the measuring unit through the air outlet can be called the pipeline pressurization stage. In the initial stage of the pipeline pressurization stage, the pressure stabilizing unit can be directly used for pressurization, and only by adjusting the pressure components (such as the number of weights) to compress air for pressurization. When pressurized to a certain stage, the air in the piston inner cavity (i.e., the first space) is compressed to a very small volume. At this time, the piston is about to touch the bottom and subsequent measurement work cannot be carried out. By controlling the operation of the air compressor, the first space is supplemented with compressed air, so as to lift the piston height to meet the measurement working conditions of the subsequent measuring unit.

[0070] In this embodiment, when the water level height in the measurement unit is stable within a preset range, the pressure in the target pipeline is stable at the current pressure at this time; the tightness of the target pipeline is detected according to the water level height in the measurement unit. If the water level height in the measurement unit is stable outside the preset range, the water volume in the water replenishing unit can be adjusted through the water supply unit. For example, the water supply unit injects water into the water replenishing unit through the water inlet of the water replenishing unit to appropriately increase the water volume, or the water supply unit pumps water through the water inlet of the water replenishing unit to reduce the water volume in the water replenishing unit; thereby adjusting the water level height of the measurement unit until the water level height is stable within the preset range. Further, through the transition of the voltage stabilizing unit, the present disclosure solves the defect in the prior art that is likely to cause damage to the target pipeline. At the same time, it solves the problem that the target pipeline cannot maintain the pressure accurately constant at a certain value, and overcomes the problem that the pressure fluctuates during the detection of the target pipeline. Further, the operation and pressure adjustment of the water replenishing unit and the voltage stabilizing unit enable the pipeline tightness testing system provided by the present disclosure to meet the market demand. Specifically, it is not easy to cause pipeline damage and secondary pollution, and there are also no problems of high cost and susceptibility to environmental interference.

[0071] Embodiment 3

[0072] Figure 5 It is a flowchart of a pipeline tightness detection method. The pipeline tightness detection method is applied to the pipeline tightness detection device as described in Embodiment 1. The pipeline tightness detection method includes the following steps:

[0073] S301. In response to the two ends of the target pipeline being blocked, control the water replenishing unit to replenish water to the target pipeline and control the bottom interface to close.

[0074] In this embodiment, when the two ends of the target pipeline are blocked, the bottom interface is closed, and the water replenishing unit replenishes water to the target pipeline; in the specific implementation process, the target pipeline can be cleaned and exhausted first, and then quickly filled with water, so as to improve the accuracy of detection. Specifically, the water replenishing unit can be a water tank. After being buffered by the water tank, it is injected into the target pipeline through the water outlet of the water tank to realize the water injection into the target pipeline until the target pipeline is filled with water, thereby providing a basic environmental condition for the pipeline tightness detection.

[0075] S302. When the target pipeline is in a full-water state, control the voltage stabilizing unit to provide pressure to the measurement unit through the air outlet and control the bottom interface to open.

[0076] In this embodiment, when the target pipeline is in a full-water state, the voltage stabilizing unit provides pressure to the measurement unit through the air outlet, and the bottom interface is open; the air is compressed by the voltage stabilizing unit to realize the pressure increase of the pipeline tightness detection device.

[0077] S303: When the water level in the measuring unit is stable within a preset range, detect the sealing performance of the target pipeline according to the water level in the measuring unit.

[0078] In this embodiment, when the water level in the measuring unit is stable within a preset range, the pressure in the target pipeline is stable at the current pressure; the sealing of the target pipeline is detected according to the water level in the measuring unit. In a specific example, if the water level in the measuring unit is stable outside the preset range, the amount of water in the water replenishment unit can be adjusted by the water supply unit, for example, the water supply unit injects water into the water replenishment unit through the water inlet of the water replenishment unit to appropriately increase the amount of water, or the water supply unit pumps water through the water inlet of the water replenishment unit to reduce the amount of water in the water replenishment unit; thereby adjusting the water level of the measuring unit until the water level is stable within the preset range. Further, after the transition of the pressure stabilizing unit, the present disclosure solves the defects of the prior art that the air compressor directly replenishes air to the target pipeline and the water pump pressurizes to the detection pressure and then closes the valve, which can easily cause damage to the target pipeline. At the same time, it solves the problem that the target pipeline cannot maintain a precise constant pressure at a certain value, and overcomes the problem of pressure fluctuations in the target pipeline during detection. Furthermore, the operation and pressure regulation of both the water replenishment unit and the pressure stabilizing unit enable the pipeline sealing test method provided by the present invention to meet market demand. Specifically, it is not easy to cause pipeline damage and secondary pollution, and there is no problem of high cost and susceptibility to environmental interference.
