[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , the present invention provides a technical solution for a laboratory pressure test device for valves used in ocean engineering: A laboratory pressure test device for valves used in ocean engineering includes an adjusting component 1. A water pressure test component 2 is slidably connected to the left side inside the adjusting component 1. The position of the water pressure test component 2 is adjusted through the adjusting component 1 to adapt to valves of different specifications; An air pressure test component 3 is fixedly connected to the right side inside the adjusting component 1. A support component 4 is arranged at the bottom ends of the water pressure test component 2 and the air pressure test component 3. The water pressure test is carried out through the water pressure test component 2, and the air pressure test is carried out through the air pressure test component 3. The support component 4 enables the two tests to be carried out simultaneously.

[0025] Please refer to Figure 1 , the adjusting component 1 includes a test base 12. A moving groove is opened at the top end of the test base 12. A support plate 11 is slidably connected inside the moving groove. The left end of the support plate 11 is rotatably connected to an adjusting threaded column 13. The adjusting threaded column 13 is threadedly connected to the left end of the test base 12. The left end of the adjusting threaded column 13 extends to the outside of the test base 12 and is fixedly connected to an adjusting handle 14. A moving handle is rotatably connected to the end of the adjusting handle 14 away from the adjusting threaded column 13. A communication hole is opened at the right end of the test base 12, which can connect the right side of the air pressure test component 3 with the outside air to facilitate the air pressure test.

[0026] By rotating the adjusting handle 14, the support plate 11 is pushed inward driven by the adjusting threaded column 13 to adjust the distance between the water pressure testing component 2 and the air pressure testing component 3, facilitating the testing of air pressure testing components 3 of different specifications and models.

[0027] Please refer to Figure 2 , the water pressure testing component 2 includes a transmission supercharging assembly 21. The left end of the transmission supercharging assembly 21 is rotatably connected to the right end of the support plate 11. The outer surface above the right end of the transmission supercharging assembly 21 is slidably connected to a water pressure chamber 22. A fixed block 25 is fixedly connected to the right end of the water pressure chamber 22. An exhaust valve is fixedly connected to the top of the water pressure chamber 22. An inlet and outlet is opened at the right side of the inner bottom end of the water pressure chamber 22. A water inlet and outlet pipe 24 is fixedly connected inside the inlet and outlet. A blocking plate 23 is slidably connected to the top of the water inlet and outlet pipe 24. The blocking plate 23 slides on the bottom end of the water pressure chamber 22. The bottom end of the water pressure chamber 22 is fixedly connected to the top end of the support assembly 4. A water pressure port is opened at one end of the water pressure chamber 22 away from the transmission supercharging assembly 21.

[0028] After the valve is installed and fixed by the fixed block 25, the exhaust valve is opened. The water pressure chamber 22 is filled with test water through the water inlet and outlet pipe 24. After filling, the exhaust valve is closed. Then, the water inlet and outlet pipe 24 is blocked by the blocking plate 23 to prevent the test water from flowing out. The water inside the water pressure chamber 22 is squeezed by the transmission supercharging assembly 21 to conduct a simulated water pressure test. After the test, the water is discharged by pulling out the blocking plate 23 to open the channel of the water inlet and outlet pipe 24.

[0029] Please refer to Figure 2 and Figure 3 , the left ends of the driven gear 211, the transmission gear 212, and the receiving gear 213 are all rotatably connected to the right end of the support plate 11.

[0030] Please refer to Figure 3 , the transmission supercharging assembly 21 includes a driven gear 211. A transmission gear 212 is meshed and connected to the top of the driven gear 211. Receiving gears 213 are meshed and connected to both the left and right sides of the top of the transmission gear 212. A pressure application screw column 214 is fixedly connected to the right end of the receiving gear 213. Two pressure application screw columns 214 are commonly threadedly connected to a first pressure application block 215. The first pressure application block 215 slides inside the water pressure chamber 22. The outer surface of the first pressure application block 215 closely adheres to the inside of the water pressure chamber 22. The end of the pressure application screw column 214 away from the receiving gear 213 is rotatably connected to the right side of the inner end of the water pressure chamber 22.

[0031] The driven gear 211 receives the force driven by the support assembly 4 to drive the transmission gear 212 to rotate, and then drives the two receiving gears 213 to rotate through its own rotation. Since the receiving gears 213 are in direct contact with the transmission gear 212, the pressure application stud 214 can be driven to rotate, and the pressure application block 215 is pushed in the water pressure chamber 22 through the rotation of the pressure application stud 214, so as to squeeze and pressurize the water inside the water pressure chamber 22, achieving the effect of testing the water pressure.

[0032] Please refer to Figure 4 , the air pressure test component 3 includes an air pressure assembly 33. The bottom end of the air pressure assembly 33 is fixedly connected to the top end of the support assembly 4. The outer surface of the left end of the air pressure assembly 33 is slidably connected with an air pressure chamber 32. The left end of the air pressure chamber 32 is fixedly connected with a mounting block 31. An air outlet is opened at one end of the air pressure chamber 32 away from the air pressure assembly 33. First, install a valve on the mounting block 31, and then the outside air is inhaled into the air pressure chamber 32 through the operation of the air pressure assembly 33 for pressurization to test the air pressure of the valve.

[0033] Please refer to Figure 4 , the air pressure assembly 33 includes a driving wheel 331. A driving column 334 is fixedly connected to the outer side of the top end of the driving wheel 331. A moving block 333 is arranged above the top end of the driving wheel 331. A propulsion groove is vertically penetrated through the middle of the moving block 333. The driving column 334 is movably arranged inside the propulsion groove. Pressure application columns 332 are fixedly connected to both the front and rear ends of the moving block 333. One end of the pressure application column 332 away from the moving block 333 extends into the air pressure chamber 32. A pressure application block 337 is fixedly connected to the ends of the two pressure application columns 332 away from the moving block 333. The outer surface of the pressure application block 337 is closely attached to the inner side of the air pressure chamber 32. The pressure application block 337 slides inside the air pressure chamber 32. Air inlet holes are opened at the right end inside the air pressure chamber 32 and the pressure application block 337. An air inlet cover plate 335 covers the left end of the air inlet hole. A hinge 336 is fixedly connected to the top end of the air inlet cover plate 335. One end of the hinge 336 away from the air inlet cover plate 335 is fixedly connected to the right side inside the air pressure chamber 32 and the left end of the pressure application block 337.

[0034] By driving the driving wheel 331 to rotate under the drive of the support component 4, the driving column 334 is driven to rotate around the center of the driving wheel 331, and during the rotation process, the moving block 333 is driven to perform reciprocating left and right movements through the propulsion groove. The pressing column 332 drives the second pressing block 337 to perform reciprocating movements together under the drive of the moving block 333. During the leftward movement of the second pressing block 337, the air on the left side of the second pressing block 337 is compressed, causing the air pressure on the right side to decrease. The intake cover plate 335 on the right side will open to the left under the pressure of the external air, allowing the external air to enter the right chamber. Then, the second pressing block 337 moves to the right under the drive of the pressing column 332, and the air in the right chamber is squeezed and enters the left chamber through the left intake cover plate 335. Since the intake cover plate 335 covers the intake hole and the hinge 336 restricts the intake cover plate 335 to only open inward, it is ensured that the gas in the chamber will not leak, thereby increasing the air pressure in the left chamber and detecting the air pressure of the valve.

[0035] Please refer to Figures 2 to 5 , the support component 4 includes a power column 41. A drive motor is provided at the left end of the power column 41. A driving gear 42 is slidably connected to the outer surface of the left side of the power column 41. The top of the driving gear 42 meshes with the bottom end of the driven gear 211. A support moving block 43 is slidably connected to the middle part of the outer surface of the power column 41. The top of the support moving block 43 is fixedly connected to the bottom end of the water pressure chamber 22. One end of the power column 41 away from the driving gear 42 is fixedly connected to a driving bevel gear 44. The top of the driving bevel gear 44 is meshed and connected to a driven bevel gear 45. The top of the driven bevel gear 45 is fixedly connected to a transmission column 46. The top of the transmission column 46 is fixedly connected to the middle part of the bottom end of the driving wheel 331.

[0036] The power column 41 provides power for the operation of the entire device. The driving gear 42 transmits the force to the transmission and supercharging component 21. The support moving block 43 can cooperate with the driving gear 42 to divide the water pressure test component 2 as a whole into movable parts. The driving bevel gear 44 can provide force for the rotation of the air pressure component 33 and change the direction of the force through the driven bevel gear 45 and the transmission column 46.

[0037] Working principle:

[0038] First, install the valve at the left end of the mounting block 31, and then clamp and install the valve by turning the adjusting handle 14 with the fixing block 25. Then, when the intercepting plate 23 is pulled out, inject test water into the water pressure chamber 22 through the inlet and outlet pipe 24. When it is filled to a certain extent, insert the intercepting plate 23 to close the water inlet and outlet channels. After that, start the device. The transmission and supercharging component 21 will squeeze the water in the water pressure chamber 22 to generate water pressure, and at the same time, the air pressure component 33 will drive the second pressing block 337 to inhale and compress the gas to generate air pressure. The two pressures simultaneously detect the pressure of the valve. After the detection is completed, pull out the intercepting plate 23 to drain the water, then open the valve to release the compressed air in the air pressure chamber 32, and finally remove the valve.
