Description

Technical Field

[0001] The utility model relates to the technical field of valve test benches, in particular to a valve test bench capable of simulating complex working conditions. Background Art

[0002] A valve test bench is a device used to test valve pressure, thereby detecting the performance of the valve under different pressure conditions. The valve test bench can be used to test the eligibility of the valve, thereby preventing unqualified products from entering the market. The existing valve test bench still has certain defects when used.

[0003] In the existing technology, valve test benches are widely used before the installation of large-scale projects such as petroleum, petrochemical, nuclear power, and chemical industries, by technical supervision and quality inspection agencies, valve production units, and valve maintenance agencies. Since valves are installed in complex environments with high temperatures, it is difficult for traditional valve test benches to perform simulated tests according to the environmental conditions of the valve installation during the testing process, making the valve test bench less practical. Utility Model Content

[0004] The purpose of the present invention is to provide a valve test bench that can simulate complex working conditions, so as to solve the problem raised in the above background technology that the valve test benches currently on the market are difficult to perform simulation tests according to the environmental working conditions of the valve installation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve test bench that can simulate complex working conditions, comprising: a base, a fixed frame, a console, an instrument, a guide rod and a clamping plate, the fixed frame and the console are respectively installed on the surface of the base, the instrument is installed on the surface of the console, a guide rod is installed between the console and the fixed frame, the side of the console close to the fixed frame is connected to the clamping plate by a hydraulic push rod, and the clamping plate is slidably connected to the outside of the guide rod, a sealing box is welded between the fixed frame and the console, an inspection door is installed at the front of the sealing box, an observation window is installed inside the inspection door, a cover plate is installed on the top of the sealing box by a hinge, a fixed block is welded on the top of the sealing box away from the cover plate, the internal thread of the fixed block is connected to a threaded rod, the end of the threaded rod is connected to a rotating block, a heater is placed on the top of the sealing box, the bottom of the heater is connected to an air outlet pipe, and an exhaust fan is installed on the outside of the sealing box.

[0006] Preferably, a plug-in structure is formed between the air outlet pipe and the sealing box.

[0007] Preferably, a through hole is formed through the sealing box near the top of the cover plate.

[0008] Preferably, a mounting box is welded to the top of the base, the interior of the mounting box is connected to a rotating rod via a coupling, and a first gear is welded to the outside of the rotating rod.

[0009] Preferably, the installation box is connected to a screw rod at an inner portion close to the rotating rod via a bearing, and a second gear is welded to an outer portion of the screw rod close to the first gear.

[0010] Preferably, the outer side of the screw rod is threadedly connected to a moving block, and the end of the moving block is welded with a support seat.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the valve test bench that can simulate complex working conditions, when the threaded rod rotates, it can slide with the fixed block, and when the thread of the threaded rod slides, it can drive the rotating block to rotate and move. When one side of the rotating block rotates and moves to the surface of the heater, the rotating block can assist in limiting the position of the heater. When the hydraulic push rod is running, it can push the valve on the side of the clamping plate to be squeezed on the fixed frame, thereby completing the valve placement operation. The valve can be auxiliary supported by the support seat, so that the valve is not easy to shake during the placement process, so that the valve can be quickly fixed and placed.

[0012] 1. The valve test bench can ensure that the valve can meet the design requirements during use and prevent leakage and other faults. The valve will be installed in a high temperature environment. Traditional valve test benches are difficult to simulate complex working conditions, making the valve test bench less practical. When the threaded rod rotates, it can slide with the fixed block. When the thread of the threaded rod slides, it can drive the rotating block to rotate. When one side of the rotating block rotates and moves to the surface of the heater, the rotating block can assist in limiting the position of the heater, making it less likely for the heater to shake during use. When the heater is running, it can convert electrical energy into thermal energy and use the fan to blow the heated air into the sealed box through the outlet pipe, so that the temperature inside the sealed box gradually increases, thereby simulating the state of the valve in high temperature and complex working conditions. After the test, the exhaust fan can quickly discharge the heat inside the sealed box. By simulating the complex working conditions of the actual valve installation, the state of the valve during use can be tested, thereby improving the practicality of the valve test bench.

[0013] 2. Before testing the valve test bench, the valve needs to be placed between the fixed frame and the clamping plate and aligned. During the placement of the valve, it is usually necessary to use lifting equipment. The lifting equipment can gradually place the valve into the sealing box. During the placement process, the valve is prone to shaking. The lack of a support structure at the bottom makes it difficult to align the valve quickly. When the rotating rod rotates, it can drive the first gear to rotate. When the first gear rotates, it can engage and drive the second gear to rotate. When the second gear rotates, it can drive the screw to rotate. When the screw rotates, it can drive the moving block to slide upward. When the moving block slides, it can drive the support seat to move. When the top of the support seat moves to the bottom surface of the valve, the bottom of the valve can fall on the support seat. At this time, the valve is not easy to shake, and the hydraulic push rod on the clamping plate is started. When the hydraulic push rod is running, it can push the valve on the side of the clamping plate to squeeze it onto the fixed frame, thereby completing the valve placement operation. The support seat can provide auxiliary support for the valve, making it difficult for the valve to shake during the placement process, so that the valve can be quickly fixed and placed.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 3 It can be seen that the utility model provides a technical solution: a valve test bench that can simulate complex working conditions, including: a base 1, a fixed frame 2, a console 3, an instrument 4, a guide rod 5 and a clamping plate 6. The surface of the base 1 is respectively installed with the fixed frame 2 and the console 3, the surface of the console 3 is installed with the instrument 4, the guide rod 5 is installed between the console 3 and the fixed frame 2, the side of the console 3 close to the fixed frame 2 is connected to the clamping plate 6 through a hydraulic push rod, and the clamping plate 6 is slidably connected to the outside of the guide rod 5, a sealing box 7 is welded between the fixed frame 2 and the console 3, and the front of the sealing box 7 is welded. An inspection door 8 is installed on the top, and an observation window 9 is installed inside the inspection door 8. A cover plate 10 is installed on the top of the sealed box 7 through a hinge. A fixed block 11 is welded to the top of the sealed box 7 away from the cover plate 10. The internal thread of the fixed block 11 is connected to a threaded rod 12, and the end of the threaded rod 12 is connected to a rotating block 13. A heater 14 is placed on the top of the sealed box 7, and the bottom of the heater 14 is connected to an air outlet duct 15. An exhaust fan 16 is installed on the outside of the sealed box 7, and a plug-in structure is formed between the air outlet duct 15 and the sealed box 7. A through hole is opened through the top of the sealed box 7 near the cover plate 10.

[0021] During specific implementation, the valve test bench can ensure that the valve can meet the design requirements during use and prevent leakage and other faults. The valve will be installed in a high temperature environment. It is difficult for traditional valve test benches to simulate complex working conditions, which makes the valve test bench less practical. The heater 14 can be placed on the top of the sealed box 7 first, so that the end of the air outlet pipe 15 at the bottom of the heater 14 can be inserted into the interior of the sealed box 7. At this time, the threaded rod 12 on the outside of the heater 14 can be rotated. When the threaded rod 12 rotates, it can slide with the fixed block 11. When the threaded rod 12 slides, it can drive the rotating block 13 to rotate and move. When one side of the rotating block 13 rotates and moves to the heater 14, the rotating block 13 can assist in limiting the position of the heater 14, so that the heater 14 is not easy to shake during use. After the cover 10 is opened, the valve to be tested is placed into the sealing box 7 through the lifting equipment, so that the clamping plate 6 squeezes and fixes the valve on one side of the fixing frame 2. At this time, the heater 14 can be started. When the heater 14 is running, it can convert electrical energy into thermal energy, and use the fan to blow the heated air into the sealing box 7 through the air outlet pipe 15, so that the temperature inside the sealing box 7 gradually increases, thereby simulating the state of the valve being used under high temperature and complex working conditions. After the test is completed, the exhaust fan 16 can quickly discharge the heat inside the sealing box 7.

[0022] See Figure 1-Figure 3 It can be seen that by simulating the complex working conditions of actual valve installation, the status of the valve during use can be tested, thereby improving the practicality of the valve test bench.

[0023] See Figure 2 and Figure 4 It can be seen that a mounting box 17 is welded to the top of the base 1, the interior of the mounting box 17 is connected to a rotating rod 18 through a coupling, a first gear 19 is welded to the outside of the rotating rod 18, the interior of the mounting box 17 near the rotating rod 18 is connected to a screw rod 20 through a bearing, a second gear 21 is welded to the outside of the screw rod 20 near the first gear 19, a moving block 22 is threadedly connected to the outside of the screw rod 20, a support seat 23 is welded to the end of the moving block 22, and the material of the support seat 23 is iron.

[0024] In specific implementation, before testing, the valve test bench needs to place the valve between the fixing frame 2 and the clamping plate 6 and align the valve. During the placement of the valve, it is usually necessary to use a lifting device, and the valve can be gradually placed in the sealing box 7 by the lifting device. However, during the placement of the valve, it is easy to shake, and the lack of a supporting structure at the bottom makes it difficult to align the valve quickly. When the valve is placed between the fixing frame 2 and the clamping plate 6, and at the same time, the two ends of the valve are aligned with the docking interfaces on the fixing frame 2 and the clamping plate 6, the rotating rod 18 can be rotated forward. When the rotating rod 18 rotates, it can drive the first gear 19 to rotate When the first gear 19 rotates, it can engage and drive the second gear 21 to rotate. When the second gear 21 rotates, it can drive the screw rod 20 to rotate. When the screw rod 20 rotates, it can drive the moving block 22 to slide upward. When the moving block 22 slides, it can drive the support seat 23 to move. When the top of the support seat 23 moves to the bottom surface of the valve, the bottom of the valve can fall on the support seat 23. At this time, the valve is not easy to shake, and the hydraulic push rod on the clamping plate 6 is started. When the hydraulic push rod is running, it can push the valve on the side of the clamping plate 6 to be squeezed on the fixed frame 2, thereby completing the valve placement operation.

[0025] See Figure 2 and Figure 4 It can be seen that the support seat 23 can provide auxiliary support for the valve, so that the valve is not prone to shaking during the placement process, and the valve can be quickly fixed and placed.

[0026] In summary, when using the valve test bench that can simulate complex working conditions, the heater 14 can be placed on the top of the sealed box 7 first, so that the end of the air outlet pipe 15 at the bottom of the heater 14 can be inserted into the interior of the sealed box 7. At this time, the threaded rod 12 on the outside of the heater 14 can be rotated. When the heater 14 is running, it can convert electrical energy into thermal energy, and use the fan to blow the heated air into the sealed box 7 through the air outlet pipe 15, so that the temperature inside the sealed box 7 gradually increases, thereby simulating the state of the valve being used under high temperature and complex working conditions. After the test is completed, the exhaust fan 1 6 can quickly discharge the heat inside the sealing box 7. By simulating the complex working conditions of the actual installation of the valve, the status of the valve during use can be tested, thereby improving the practicality of the valve test bench. When the hydraulic push rod is running, it can push the valve on the side of the clamping plate 6 to be squeezed on the fixing frame 2, thereby completing the valve placement operation. The valve can be auxiliary supported by the support seat 23, making it less likely for the valve to shake during the placement process, thereby allowing the valve to be quickly fixed and placed.
