Description

Technical Field

[0001] The invention relates to the technical field of electrochemical anti-corrosion pipelines, in particular to a pressure detection device for electrochemical anti-corrosion pipelines. Background Art

[0002] Anti-corrosion steel pipe refers to a steel pipe that has been processed with anti-corrosion technology to effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use.

[0003] For example, an electrochemical anti-corrosion pipeline pressure detection device with announcement number CN214275362U can be realized through the No. 1 and No. 2 transmission devices. When the air pressure inside the pipeline is too high and it is easy to damage the pipeline, it will trigger the automatic alarm device to remind workers to check in time, and open the No. 1 gate to reduce the air pressure in the pipeline as soon as possible. However, in actual use, the No. 1 gate can be opened after the internal pressure of the pipeline increases. After the No. 1 gate is opened, the pressure inside the pipeline directly acts on the No. 1 gate. After the No. 1 gate moves, it cannot guarantee its own stable support. When subjected to greater pressure, the movement trajectory of the No. 1 gate is prone to change, affecting subsequent use, and the pipeline When the internal pressure is relatively high, the pressure relief operation is performed through the first gate and the second gate, and the moving distance of the first gate and the second gate is relatively small. At this time, when the internal pressure of the pipeline is relatively high and the pipeline needs to be stopped urgently to transport gas, the first gate and the second gate will also be quickly reset, which will cause some high-pressure gas to remain inside the pressure relief chamber. When the pipeline transports gas again, if the internal pressure of the pipeline increases again, the pressure relief operation can no longer be performed on the pipeline due to the presence of a certain amount of high-pressure gas inside the pressure relief chamber. When the pipeline is operated, if it is necessary to stop the gas transportation urgently, the high-pressure gas will remain in the pressure relief chamber, which will affect the subsequent pressure relief operation of the pipeline, and there are certain usage defects.

[0004] Therefore, we propose a pressure detection device for electrochemical anti-corrosion pipelines in order to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a pressure detection device for an electrochemical anti-corrosion pipeline, so as to solve the problem proposed in the above-mentioned background technology that after the internal pressure of the pipeline increases, the No. 1 gate can be opened. After the No. 1 gate is opened, the pressure inside the pipeline directly acts on the No. 1 gate. After the No. 1 gate moves, it cannot ensure its own stable support. When subjected to a large pressure, the movement trajectory of the No. 1 gate is prone to change, affecting subsequent use. When the internal pressure of the pipeline is large, the pressure relief operation is performed through the first gate and the No. 2 gate, and the moving distance of the No. 1 gate and the No. 2 gate is small. At this time, when the internal pressure of the pipeline is large and it is necessary to stop the gas transportation to the pipeline urgently, the No. 1 gate and the No. 2 gate will also be quickly reset, which will cause part of the high-pressure gas to remain in the pressure relief chamber. When the pipeline transports gas again, if the internal pressure of the pipeline increases again, since there is already a certain amount of high-pressure gas in the pressure relief chamber, the pipeline can no longer be pressure-relieved. When the pipeline is operated, if it is necessary to stop the gas transportation urgently, the high-pressure gas will remain in the pressure relief chamber, which will affect the subsequent pressure relief operation of the pipeline.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the pressure detection device for electrochemical anti-corrosion pipeline is provided with a movable component inside the connecting pipe below the air permeable plate, so that the pipeline body can be depressurized to avoid damage to the pipeline body caused by excessive pressure inside the pipeline, and when the gas is urgently stopped for transportation, the high-pressure gas inside the pressure relief chamber can be prevented from always remaining inside the pressure relief chamber, and the pressure balance between the pressure relief chamber and the pipeline body can be ensured to avoid affecting the subsequent pressure relief operation on the pipeline body; When the pressure inside the pipeline body increases, the second slot on the movable plate and the first slot on the movable plate are staggered with each other, and the movable plate remains in a closed state.

[0026] Embodiment 1: Figure 1-Figure 3As shown, a moving assembly 2 is arranged below the air-permeable plate 105 inside the connecting pipe 101. When the pressure inside the pipeline body 1 increases, the second through slot 216 on the movable plate 215 and the first through slot 205 on the moving plate 201 are staggered with each other, and the moving plate 201 remains in a closed state. The pressure inside the pipeline body 1 increases, and the moving plate 201 can be pushed up to move. The moving plate 201 moves to drive the support rod 202 to slide on the support block 203 and compress the support spring 204, and the moving rod 206 is fitted with the air-permeable plate 105. Then, the moving plate 201 continues to move to fit with the air-permeable plate 105, and one end of the moving rod 206 is fitted with the air-permeable plate 105. The gas plate 105 is in contact and no longer moves, so that after the movable plate 201 moves, it drives the rotating rod 213 on the fixed frame 212 to move. After the rotating rod 213 moves, it is meshed with the toothed plate 211 through the rotating gear 214, so that the rotating rod 213 can rotate. After the rotating rod 213 rotates, it can drive the two rotating members 221 to rotate. After the rotating member 221 rotates, it can push the two movable frames 220 to move, thereby driving the two groups of movable plates 215 to move at the same time. After the movable plates 215 move, the second through grooves 216 on the two left movable plates 215 are aligned with the two left groups of first through grooves 205 on the movable plate 201, so that the inside of the pipeline body 1 The high-pressure gas can pass through the second through groove 216 and the first through groove 205, so that the gas can enter the interior of the pressure relief chamber 102, and the pipeline body 1 can be depressurized. If the gas delivery inside the pipeline body 1 stops, the pressure inside the pipeline body 1 drops rapidly, and the support spring 204 recovers its deformation, so that the movable plate 201 is reset, and the high-pressure gas inside the pressure relief chamber 102 can push the movable plate 201 to move downward. After the movable plate 201 moves downward, the bottom end of the movable rod 206 abuts against the cross bar 104, and the movable plate 201 continues to descend under the action of pressure, so that the rotating rod 213 can rotate in the opposite direction, so that The second through grooves 216 of the two movable plates 215 on the right are aligned with the first through grooves 205 on the right side of the movable plate 201, so that the pressure relief operation can be performed on the pressure relief chamber 102, thereby ensuring that the pressure inside the pressure relief chamber 102 is balanced with the pressure inside the pipeline body 1. The pipeline body 1 can be depressurized by moving the component 2 to avoid damage to the pipeline body 1 due to excessive pressure inside the pipeline. When the gas is transported in an emergency, the high-pressure gas inside the pressure relief chamber 102 can be prevented from always remaining in the pressure relief chamber 102, so that the pressure balance between the pressure relief chamber 102 and the pipeline body 1 can be ensured, avoiding affecting the subsequent pressure relief operation on the pipeline body 1.

[0027] Two groups of positioning frames 222 are symmetrically installed on both sides of the two groups of movable plates 215 at the bottom of the movable plate 201, and the positioning frames 222 are slidably connected to the inside of the positioning frames 223, and one end of the two groups of positioning rods 223 are respectively fixedly connected to the two groups of movable plates 215.

[0029] A sliding rod 106 is slidably connected to one side of the inner part of the air-permeable plate 105, and a tension spring 107 is sleeved on the outer part of the sliding rod 106, and one end of the tension spring 107 is fixedly connected to the air-permeable plate 105, and a connecting block 1061 is fixedly installed on the other end of the tension spring 107, and the connecting block 1061 is fixedly connected to the sliding rod 106, and a movable block 108 is fixedly installed on the top of the sliding rod 106, and a movable groove 109 is opened through one side of the movable block 108, and a column 110 is slidably connected to the inside of the movable groove 109, and mounting brackets 111 are fixedly installed at both ends of the column 110, and a connecting rod 112 is fixedly installed on one side of the mounting bracket 111, and the connecting rod 112 is slidably connected to the connecting pipe 101; A support frame 114 is fixedly installed on the outside of the connecting tube 101 above the alarm 103, and a pressing rod 115 is slidably connected inside the support frame 114, and a protrusion 113 is fixedly installed on one side of the bottom of the connecting rod 112, and a ball 116 is hinged on the top of the pressing rod 115, and the ball 116 is rotatably connected to the protrusion 113.

[0030] Embodiment 3: Figure 1-Figure 2 and Fig. 9As shown, when the pipeline body 1 is depressurized, the upward movement of the movable plate 201 can push the sliding rod 106 to move upward. After the sliding rod 106 moves upward, the tension spring 107 is stretched. After the sliding rod 106 moves upward, it drives the movable block 108 to move upward. The movement of the movable block 108 can push the column 110 to move through the sliding connection between the column 110 and the movable groove 109. After the column 110 moves, it drives the connecting rod 112 to move. The movement of the connecting rod 112 causes the protrusion 113 to move and push the ball 116 downward, so that the pressing rod 115 moves downward, and then the pressing rod 115 can press the button on the alarm 103, so that the alarm 103 can operate and sound an alarm, which can remind the staff, and after the sliding rod 106 is reset, the button itself can be automatically reset after moving, so that it can be used again, and then when the pipeline body 1 is depressurized, an alarm can be sounded to remind the staff to check, thereby improving practicality.

[0031] Working principle: When using the electrochemical anti-corrosion pipeline pressure detection device, first, according to Figure 1-Figure 9As shown, when the internal pressure of the pipeline body 1 increases, the second through slot 216 on the movable plate 215 and the first through slot 205 on the movable plate 201 are staggered with each other, and the movable plate 201 remains in a closed state. The internal pressure of the pipeline body 1 increases and the movable plate 201 can be pushed up. The movement of the movable plate 201 drives the support rod 202 to slide on the support block 203 and compress the support spring 204, and makes the movable rod 206 fit with the air-permeable plate 105, and then the movable plate 201 continues to move and fits with the air-permeable plate 105 One end of the moving rod 206 abuts against the air-permeable plate 105 and does not move, so that the moving plate 201 moves and drives the rotating rod 213 on the fixed frame 212 to move. After the rotating rod 213 moves, the rotating gear 214 is meshed with the toothed plate 211, so that the rotating rod 213 can rotate. After the rotating rod 213 rotates, it can drive the two rotating members 221 to rotate. After the rotating member 221 rotates, it can push the two movable frames 220 to move, thereby driving the two sets of movable plates 215 to move at the same time. When the movable plates 215 move, The second through grooves 216 on the two movable plates 215 on the left side of the rear are aligned with the two groups of first through grooves 205 on the left side of the movable plate 201, so that the high-pressure gas inside the pipeline body 1 can pass through the second through grooves 216 and the first through grooves 205, so that the gas can enter the interior of the pressure relief chamber 102, and the pipeline body 1 can be depressurized. If the gas delivery inside the pipeline body 1 stops, the pressure inside the pipeline body 1 drops rapidly, and the support spring 204 recovers its deformation, so that the movable plate 201 is reset, and the pressure relief chamber 102 is The high-pressure gas can push the movable plate 201 to move downward. After the movable plate 201 moves downward, the bottom end of the movable rod 206 abuts against the cross bar 104, and the movable plate 201 continues to descend under the pressure, so that the rotating rod 213 can rotate in the opposite direction, so that the second through grooves 216 of the two movable plates 215 on the right side can be aligned with the first through groove 205 on the right side of the movable plate 201, so that the pressure relief chamber 102 can be relieved, so as to ensure that the pressure inside the pressure relief chamber 102 is balanced with the pressure inside the pipeline body 1; When the movable plate 201 moves and drives the movable plate 215 to move, the movable plate 215 can drive the two sets of positioning rods 223 to slide on the positioning frame 222, so that the reset spring 224 can be stretched or compressed, and then the movement of the movable plate 215 can be limited, and the movement of the movable plate 215 can be automatically reset, so as to facilitate the subsequent pressure relief of the pressure relief chamber 102, thereby improving the practicality. When the pipeline body 1 is pressure-relieved, the upward movement of the movable plate 201 can push the sliding rod 106 to move upward, and the sliding rod 106 moves upward to stretch the tension spring 107, and the sliding rod 106 moves upward to drive the movable block 108 to move upward, and the movable block 108 moves upward. 08 Movement can be achieved by pushing the column 110 to move through the sliding connection between the column 110 and the movable groove 109. After the column 110 moves, it drives the connecting rod 112 to move. The movement of the connecting rod 112 causes the protrusion 113 to move and push the ball 116 downward, so that the pressing rod 115 moves downward, and then the pressing rod 115 can press the button on the alarm 103, so that the alarm 103 can operate and sound an alarm, which can remind the staff, and after the sliding rod 106 is reset, the button itself can be automatically reset after moving, so that it can be used again, and then when the pipeline body 1 is depressurized, an alarm can be sounded to remind the staff to check, thereby improving practicality.
