Description

Technical Field

[0001] The present invention relates to the technical field of water pressure testing, in particular to an adjustable water pressure testing device. Background Art

[0002] During the manufacturing process of pressure vessels, there is generally a pressure test process. The pressure test of most pressure vessels is carried out with water as the medium. The basic principle is to connect a pressure gauge to the connecting pipe of the pressure vessel, and then inject excess water into the pressure vessel to make the pressure vessel have a higher water pressure. The pressure vessel is maintained under this water pressure for a period of time. If a leak occurs during this period, the pressure gauge reading will decrease. According to whether the pressure gauge reading changes, it can be judged whether the pressure resistance performance of the pressure vessel meets the standard.

[0003] For example, a pressure vessel water pressure test device with announcement number CN218382110U can adjust the distance between the two support seats according to the length of the pressure vessel. After adjustment, positioning pins are used for positioning to adapt to the use of pressure vessels of different lengths. When not in use, it can be retracted to reduce the space occupied. The pressure vessel is placed on the support roller, and the drive motor is started. The drive motor drives the support roller to rotate through the drive roller, thereby driving the pressure vessel to rotate, causing the pressure vessel to rotate and subjecting different areas of the inner wall of the pressure vessel to the same water pressure to improve the accuracy of the test results. However, in actual use, during the pressure test, although the pressure vessel can be rotated, water is passed through the pressure vessel to pressurize the inside of the pressure vessel. The water flow range is relatively single and the water flow and pressurization range is fixed. As a result, after the pressurized water enters the pressure vessel, the pressure inside the pressure vessel will be uneven. Although the pressure can be evenly distributed by rotating the pressure vessel, due to the fixed range of pressurized water addition, more time is required to make the pressure vessel uniform, which reduces the efficiency of the pressure vessel water pressure test and has certain usage defects.

[0004] Therefore, we propose an adjustable water pressure test device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable water pressure testing device to solve the problem raised in the above background technology that when conducting a pressure test, although the pressure vessel can be rotated and water is passed through the interior of the pressure vessel to pressurize it, the water passing range is relatively single and the range of water pressurization is fixed, so that after the pressurized water enters the pressure vessel, the pressure inside the pressure vessel will be uneven. Although the pressure can be evenly distributed by rotating the pressure vessel later, since the pressurized water addition range is fixed, more time is required to make the interior of the pressure vessel uniform, which reduces the working efficiency of the pressure vessel water pressure test.

[0027] Compared with the prior art, the present invention has the following beneficial effects: the adjustable hydraulic pressure test device is provided with a pressure relief assembly on the top of the base and inside the pressure vessel, so that when the pressure vessel is subjected to a hydraulic pressure test, the pressurization range can be expanded, thereby avoiding uneven pressure inside the pressure vessel and affecting the accuracy of the hydraulic pressure test; the pressurization range can be adjusted and swung, so that the pressure inside the pressure vessel is evenly distributed, thereby improving the efficiency of the hydraulic pressure test of the pressure vessel;

[0028] 1. A test assembly is set at the top of the base and the inside of the pressure vessel. When the pressure vessel is subjected to a water pressure test, the pressure vessel is placed above the rotating assembly, and then the sealing gasket on the mounting plate is tightly fitted with the opening of the pressure vessel to seal the pressure vessel. A pressure sensor is set on the mounting plate to know the internal pressure value of the pressure vessel. Then water is passed into the pressure vessel through the water inlet pipe, and the air inside the pressure vessel is discharged through the exhaust pipe. Pressurized water is passed through the pressurized pipe so that the pressurized water enters the installation pipe. At this time, the pressure vessel rotates. During the rotation of the pressure vessel, the pressurized pipe and the water inlet pipe are connected to the connecting pipe through a rotary joint. The pressure vessel can be controlled to rotate back and forth by the rotating assembly to avoid entanglement of the connecting pipes on the pressurized pipe and the water inlet pipe. The pressurized pipe and the pressure vessel can rotate synchronously. After the pressure pipe rotates, the installation pipe can not rotate with the pressure pipe under the action of the counterweight block and the rotary joint. The pressure pipe and the mounting plate are aligned The rotation of the same drives the inner gear ring to rotate, and the meshing rotating gear can drive the rotating shaft to rotate. After the rotating shaft rotates, it can drive the cam to rotate. After the cam rotates, it can push up the movable plate, so that the telescopic spring can be stretched. After the cam rotates, the movable plate is reset under the action of the telescopic spring. The rotation of the pressure vessel can make the movable plate reciprocate. After the movable plate moves, it can be pulled by the movable sleeve to rotate. The rotation of the rotating plate causes the movable sleeve to slide on the mounting rod, so that the rotating plate rotates back and forth continuously. After the rotating plate rotates back and forth, it can drive the water outlet pipe to rotate continuously. Pressurized water enters the pressure vessel through the water outlet pipe. The reciprocating swing of the water outlet pipe can increase the pressurization range. Through the test assembly, the pressurization range can be expanded when the pressure vessel is subjected to a water pressure test, thereby avoiding uneven pressure inside the pressure vessel and affecting the accuracy of the water pressure test. The pressure inside the pressure vessel can be evenly distributed, thereby improving the water pressure test efficiency of the pressure vessel.

[0029] 2. When fixing the pressure vessel, one side sliding plate is moved upward according to the size of the pressure vessel. After the sliding plate moves, the mounting plate can be driven to move so that the mounting tube is inserted into the pressure vessel and the mounting plate fits with the opening of the pressure vessel. The sliding plate on the other side is moved so that the rubber pad on the rotating seat fits with the other side of the pressure vessel. Then, the hand wheel is turned to drive the threaded rod to rotate. After the threaded rod is rotated, the movable sleeve and the mounting plate can be pushed to move through the threaded connection of the sliding plate, so that the sealing gasket on the mounting plate fits tightly with the pressure vessel. The rotation of the threaded rod can also be driven by a replacement motor, so that the pressure vessel can be fixed between the rotating seat and the mounting plate. The pressure vessel can drive the rotating seat to rotate during the rotation process, and can also drive the movable seat to rotate. After the movable seat rotates, the limiting ring slides outside the two arc blocks, which makes it convenient for the staff to limit the pressure vessel, thereby improving convenience and practicality.

[0030] 3. When the pressure vessel is placed on the two curved plates, it fits with the two rollers. Pressure vessels of different sizes can be moved by pressing down the rotating roller. The rotating roller can push the moving rod to slide on the curved plate through the movable frame, so that the support spring can be stretched, making it suitable for pressure vessels of different sizes. After that, the drive motor can be started to drive the roller to rotate, so that the pressure vessel can be driven to rotate, which can help to evenly distribute the pressure inside the pressure vessel and improve practicality.

A rotating gear 211 is fixedly mounted on one end of the rotating shaft 210, and the rotating gear 211 is meshed with the inner gear ring 208.

[0047] The water outlet pipe 212 is symmetrically connected to the outside of the mounting pipe 206 near the counterweight block 207. A cam 213 is fixedly installed on the end of the two rotating shafts 210 away from the rotating gear 211. Two sets of fixed rods 214 are symmetrically installed on the outside of the mounting pipe 206 on one side of the two mounting blocks 209. The outside of each set of two fixed rods 214 is slidably connected to a movable plate 215. At the same time, the cam 213 is slidably connected to the movable plate 215.

[0048] A telescopic spring 216 is sleeved on one side of the outer portion of the fixed rod 214, and one end of the telescopic spring 216 is fixedly connected to the movable plate 215, and a connecting block 217 is fixedly installed on the other end of the telescopic spring 216, and the connecting block 217 is fixedly connected to the fixed rod 214;

[0049] Two sets of support frames 218 are symmetrically installed on the outside of the installation pipe 206 near the two water outlet pipes 212, and a rotating plate 219 is hinged between each set of two support frames 218. A mounting ring 220 is fixedly installed on the outside of the water outlet pipe 212, and the mounting ring 220 is fixedly connected to the rotating plate 219.

[0050] A fixed block 221 is symmetrically installed on one side of the bottom of the rotating plate 219, and a mounting rod 222 is fixedly installed between the two fixed blocks 221, and a movable sleeve 223 is sleeved on the outer side of the mounting rod 222. At the same time, the movable sleeve 223 is hinged to the movable plate 215, and the movable plate 215 and the rotating plate 219 are both permeable mesh plates.

[0051] Example 1: Figure 1-Figure 5As shown, a test assembly 2 is set on the top of the base 1 and inside the pressure vessel 101. When the pressure vessel 101 is subjected to a water pressure test, the pressure vessel 101 is placed above the rotating assembly 3, and then the sealing gasket 204 on the mounting plate 201 is tightly fitted with the opening of the pressure vessel 101 to seal the pressure vessel 101. A pressure sensor is set on the mounting plate 201 to obtain the internal pressure value of the pressure vessel 101. Then, water is introduced into the pressure vessel 101 through the water inlet pipe 203, and the air inside the pressure vessel 101 is discharged through the exhaust pipe 102. The pressure is then introduced into the pressure vessel 101 through the pressurizing pipe 202. The pressure vessel 101 rotates, and the pressure pipe 202 is connected to the water inlet pipe 203 through a rotary joint and a connecting pipe. The pressure vessel 101 can be controlled to rotate back and forth by the rotating component 3 to avoid the pressure pipe 202 and the connecting pipe on the water inlet pipe 203 from being entangled. The pressure pipe 202 and the pressure vessel 101 can rotate synchronously. After the pressure pipe 202 rotates, the mounting pipe 206 can not rotate together with the pressure pipe 202 under the action of the counterweight block 207 and the rotary joint. The pressure pipe 202 and the mounting pipe are connected. The plate 201 rotates together to drive the inner gear ring 208 to rotate, and the meshing rotating gear 211 can drive the rotating shaft 210 to rotate. After the rotating shaft 210 rotates, it can drive the cam 213 to rotate. After the cam 213 rotates, the movable plate 215 can be lifted up, so that the telescopic spring 216 can be stretched. After the cam 213 rotates, the movable plate 215 is reset under the action of the telescopic spring 216. The rotation of the pressure vessel 101 can make the movable plate 215 reciprocate. After the movable plate 215 moves, it can pull the rotating plate 219 to rotate through the movable sleeve 223. The rotation of the rotating plate 219 makes the movable plate 215 reciprocate. The movable sleeve 223 slides on the mounting rod 222, causing the rotating plate 219 to rotate back and forth continuously. After the rotating plate 219 rotates back and forth, it can drive the water outlet pipe 212 to rotate continuously. The pressurized water enters the interior of the pressure vessel 101 through the water outlet pipe 212. The reciprocating swing of the water outlet pipe 212 can increase the pressurization range. Through the test assembly 2, when the pressure vessel 101 is subjected to a water pressure test, the pressurization range can be expanded to avoid uneven pressure inside the pressure vessel 101 and affect the accuracy of the water pressure test. The pressure inside the pressure vessel 101 can be evenly distributed, thereby improving the water pressure test efficiency of the pressure vessel 101.

[0052] A vertical plate 224 is symmetrically mounted on the top of the base 1, and a sliding plate 225 is disposed above the vertical plate 224. A sliding groove 226 is formed at the bottom of the sliding plate 225. The sliding plate 225 is slidably connected to the sliding groove 226. A threaded rod 227 is connected to the internal thread of one side of the sliding plate 225. A rotating seat 233 is rotatably connected to the side of the other side of the sliding plate 225 close to the pressure vessel 101, and a rubber pad is fixedly mounted on one side of the rotating seat 233.

At the same time, the fixing ring 229 is fixedly connected to the mounting plate 201, and the pressure pipe 202 and the water inlet pipe 203 are both connected through the fixing ring 229, and a limiting ring 231 is fixedly installed on the other side of the movable seat 228, and the interior of one side sliding plate 225 is symmetrically slidably connected to the support rod 230 on both sides of the threaded rod 227, and an annular groove is opened inside the limiting ring 231, and the interior of the limiting ring 231 is symmetrically slidably connected to the arc block 232 through the annular groove, and one end of the two support rods 230 is fixedly connected to the two arc blocks 232 respectively.

[0054] Example 2: Figure 1 and Figure 6-Figure 7 As shown, after fixing the pressure vessel 101, the sliding plate 225 on one side is moved upward according to the size of the pressure vessel 101. After the sliding plate 225 moves, the mounting plate 201 can be driven to move, so that the mounting tube 206 is inserted into the pressure vessel 101, and the mounting plate 201 fits with the opening of the pressure vessel 101. The sliding plate 225 on the other side is moved so that the rubber pad on the rotating seat 233 fits with the other side of the pressure vessel 101. Then, the hand wheel is turned to drive the threaded rod 227 to rotate. After the threaded rod 227 rotates, the movable sleeve 223 can be pushed through the threaded connection of the sliding plate 225. It moves with the mounting plate 201, so that the sealing gasket 204 on the mounting plate 201 is in close contact with the pressure vessel 101. The rotation of the threaded rod 227 can also be driven by a replacement motor, so that the pressure vessel 101 can be fixed between the rotating seat 233 and the mounting plate 201. During the rotation process, the pressure vessel 101 can drive the rotating seat 233 to rotate, and can also drive the movable seat 228 to rotate. After the movable seat 228 rotates, the limiting ring 231 slides outside the two arc blocks 232, thereby making it convenient for the staff to limit the pressure vessel 101, thereby improving convenience and practicality.

[0055] The rotating assembly 3 is symmetrically arranged outside and below the pressure vessel 101;

[0056] The rotating assembly 3 includes a curved plate 301 symmetrically mounted on the top of the base 1 below the pressure vessel 101, and a connecting groove 302 is formed at the bottom end of the curved plate 301. Support blocks 303 are symmetrically mounted inside the connecting groove 302. A roller shaft 304 is rotatably connected between the two support blocks 303. A drive motor is fixedly mounted on one side of one support block 303, and the output end of the drive motor passes through the support block 303 and is fixedly connected to the roller shaft 304. Two sets of through grooves 305 are symmetrically formed on both sides of the interior of the curved plate 301.

[0057] A movable frame 308 is provided inside the through slot 305, and a rotating roller 309 is rotatably connected to the inside of the movable frame 308, and a moving rod 306 is symmetrically installed on the other side of the movable frame 308. At the same time, a support spring 307 is sleeved on one side of the outside of the moving rod 306, and one end of the support spring 307 is fixedly connected to the arc plate 301, and the other end of the support spring 307 is fixedly connected to the moving rod 306.

[0058] Example 3: Figure 1 and Figure 8-Figure 9 As shown, when the pressure vessel 101 is placed on the two curved plates 301, it fits with the two rollers 304. Pressure vessels 101 of different sizes can press down the rotating roller 309 to move. The rotating roller 309 can push the moving rod 306 to slide on the curved plate 301 through the movable frame 308, so that the support spring 307 can be stretched, making it suitable for pressure vessels 101 of different sizes. After that, the driving motor can be started to drive the roller 304 to rotate, so that the pressure vessel 101 can be driven to rotate, which can help to evenly distribute the pressure inside the pressure vessel 101, thereby improving practicality.

[0059] Working principle: When using the adjustable water pressure test device, first, according to Figures 1-9As shown, a test assembly 2 is set on the top of the base 1 and inside the pressure vessel 101. When the pressure vessel 101 is subjected to a water pressure test, the pressure vessel 101 is placed above the rotating assembly 3, and then the sealing gasket 204 on the mounting plate 201 is tightly fitted with the opening of the pressure vessel 101 to seal the pressure vessel 101. A pressure sensor is set on the mounting plate 201 to obtain the internal pressure value of the pressure vessel 101. Then, water is introduced into the pressure vessel 101 through the water inlet pipe 203, and the air inside the pressure vessel 101 is discharged through the exhaust pipe 102. The pressure is then introduced into the pressure vessel 101 through the pressurizing pipe 202. The pressure vessel 101 rotates, and the pressure pipe 202 is connected to the water inlet pipe 203 through a rotary joint and a connecting pipe. The pressure vessel 101 can be controlled to rotate back and forth by the rotating component 3 to avoid the pressure pipe 202 and the connecting pipe on the water inlet pipe 203 from being entangled. The pressure pipe 202 and the pressure vessel 101 can rotate synchronously. After the pressure pipe 202 rotates, the mounting pipe 206 can not rotate together with the pressure pipe 202 under the action of the counterweight block 207 and the rotary joint. The pressure pipe 202 and the mounting pipe are connected. The plate 201 rotates together to drive the inner gear ring 208 to rotate, and the meshing rotating gear 211 can drive the rotating shaft 210 to rotate. After the rotating shaft 210 rotates, it can drive the cam 213 to rotate. After the cam 213 rotates, the movable plate 215 can be lifted up, so that the telescopic spring 216 can be stretched. After the cam 213 rotates, the movable plate 215 is reset under the action of the telescopic spring 216. The rotation of the pressure vessel 101 can make the movable plate 215 reciprocate. After the movable plate 215 moves, it can pull the rotating plate 219 to rotate through the movable sleeve 223. The rotation of the rotating plate 219 makes the movable plate 215 reciprocate. The movable sleeve 223 slides on the mounting rod 222, causing the rotating plate 219 to continuously rotate back and forth. The reciprocating rotation of the rotating plate 219 can drive the water outlet pipe 212 to continuously rotate, and the pressurized water is passed into the interior of the pressure vessel 101 through the water outlet pipe 212. The reciprocating swing of the water outlet pipe 212 can increase the pressurization range. The test assembly 2 can expand the pressurization range when performing a hydrostatic test on the pressure vessel 101, avoid uneven pressure inside the pressure vessel 101, avoid affecting the accuracy of the hydrostatic test, and evenly distribute the pressure inside the pressure vessel 101, thereby improving the efficiency of the hydrostatic test of the pressure vessel 101.

[0060] After the pressure vessel 101 is fixed, the sliding plate 225 on one side is moved upward according to the size of the pressure vessel 101. After the sliding plate 225 moves, the mounting plate 201 can be driven to move, so that the mounting tube 206 is inserted into the pressure vessel 101, and the mounting plate 201 is fitted with the opening of the pressure vessel 101, and the sliding plate 225 on the other side is moved so that the rubber pad on the rotating seat 233 is fitted with the other side of the pressure vessel 101. Then, the hand wheel is turned to drive the threaded rod 227 to rotate. After the threaded rod 227 rotates, the threaded connection of the sliding plate 225 can push the movable sleeve 223 and the mounting plate 201 to move, so that the sealing gasket 204 on the mounting plate 201 is tightly fitted with the pressure vessel 101. The rotation of the threaded rod 227 can also be driven by a motor, so that the pressure vessel 101 can be fixed between the rotating seat 233 and the mounting plate 201. The pressure vessel 101 is During the rotation process, the rotating seat 233 can be driven to rotate, and the movable seat 228 can be driven to rotate. After the movable seat 228 rotates, the limiting ring 231 slides outside the two arc blocks 232, which makes it convenient for the staff to limit the pressure vessel 101, thereby improving convenience and practicality. When the pressure vessel 101 is placed on the two arc plates 301, it fits with the two rollers 304. Pressure vessels 101 of different sizes can press down the rotating roller 309 to move. The rotating roller 309 can push the moving rod 306 to slide on the arc plate 301 through the movable frame 308, so that the support spring 307 can be stretched, so that it can be suitable for pressure vessels 101 of different sizes. After that, the drive motor can be started to drive the roller 304 to rotate, so that the pressure vessel 101 can be driven to rotate, which can help to evenly distribute the pressure inside the pressure vessel 101, thereby improving practicality.
