The sensor in the equipment measures the pressure change in real time within the set time to judge the air tightness of the valve. Marine valve air tightness test equipment is an indispensable and important equipment in the shipbuilding industry. It can effectively ensure the production quality of marine valves and improve the safety of ship navigation.

The device can automatically position the valve and perform air tightness test on the valve, simulate the ship navigation scene during the test, and improve the test accuracy.

[0004] The above-mentioned "a marine valve air tightness test device" still has some shortcomings.

[0053] A test method for marine valve air tightness test equipment comprises the following steps:

[0054] S1. First, place the marine valve body 6 to be tested on the surface of the top support seat 701. After the two electric push rods 703 are started, the electric push rod 703 on the inner side of the side protection plate 702 can be started to drive the clamping frame 704 to move horizontally, so that the marine valve body 6 can be clamped by the horizontally movable clamping frame 704, which is convenient for subsequent stable testing. During the test, the marine valve body 6 can be protected by the protection box 4, and the marine valve body 6 can be observed in a portable manner by using the observation window 5 opened on the surface of the protection box 4;

[0055] S2. At the beginning of the test, the motor body 802 on the top of the side support seat 801 is first started, and the motor body 802 drives the drive shaft 803 to rotate. The rotating drive shaft 803 can drive the side transmission disk 804 to rotate, and the rotating side transmission disk 804 will drive the side sleeve rod 805 to rotate along the axis of the side transmission disk 804.

Through the connection of the No. 1 bearing plate 8016, the top connecting plate 8014 and the top support column 8015 can be driven to adjust the height during the vertical movement of the side support column 8010. The motor body 802 drives the side support column 8010 to move up and down continuously, which can drive the top support seat 701 to reciprocate up and down, so that the effect of the marine valve body 6 when simulating the repeated up and down bumps of the ship can be portable evaluated, thereby improving the efficiency of the test;

[0056] S3. When the motor body 802 drives the driving shaft 803 to rotate, the side transmission bevel gear 909 will be driven to rotate synchronously. The rotating side transmission bevel gear 909 can drive the top transmission bevel gear plate 903 to rotate synchronously by meshing with the top transmission bevel gear plate 903.

[0057] S4. When the side meshing toothed disc 908 rotates, the meshing of the side meshing toothed disc 908 and the connecting gear 1007 can drive the connecting gear 1007 to rotate synchronously, and the connecting gear 1007 is supported by the movable side rod 1006 during its rotation, and the bottom end of the movable side rod 1006 is movably connected to the surface of the connecting side plate 1004 through the third bearing disc 1005, and the connecting side plate 1004 can be used to support the movable side rod 1006 on the top of the third bearing disc 1005, and the cooling fan 100 is driven by the rotating connecting gear 1007. 8 rotates, which can generate wind in the bottom box body 2 and blow toward the inner side of the protection box 4 along the top exhaust port 1010, thereby reducing the temperature in the protection box 4 and changing the test environment. When the temperature in the protection box 4 needs to be increased, the controller 1002 can be started to drive the electric heater 1003 to work. After the electric heater 1003 generates high temperature, the heat will be blown toward the surface of the marine valve body 6 along the rotating cooling fan 1008, thereby increasing the temperature of the marine valve body 6, making it easy to test the effect of the marine valve body 6 working continuously at high temperature and improving the diversity of the test.

7. A test method for a marine valve air tightness test device, applied to a marine valve air tightness test device as claimed in any one of claims 1 to 6, characterized in that: The steps include: S1. First, a marine valve body (6) to be tested is placed on the surface of the top support seat (701), and after two electric push rods (703) are started, the electric push rod (703) on the inner side of the side protection plate (702) is started to drive the clamping frame (704) to move horizontally, so that the marine valve body (6) is clamped by the horizontally moving clamping frame (704); S2. At the beginning of the test, after the motor body (802) on the top of the side support seat (801) is started, the motor body (802) drives the drive shaft (803) to rotate, and the rotating drive shaft (803) drives the side transmission plate (804) to rotate, and the sleeve hole (808) on the surface of the sleeve ring (807) is connected with the side sleeve rod (805). When the side sleeve rod (805) moves, the sleeve ring (807) is driven to move vertically up and down, and through the connection of the top connecting rod (806), the top connecting plate (809) and the side support column (8010) are driven to move vertically; S3, while the motor body (802) drives the driving shaft (803) to rotate, it drives the side transmission bevel gear (909) and the top transmission bevel gear plate (903) to rotate synchronously, and the top transmission bevel gear plate (903) drives the top sleeve seat (904) and the top sleeve connecting rod (906) to rotate, which drives the top connecting plate (8014) to rotate. At the same time, when the side support column (8010) moves vertically, the top sleeve connecting rod (906) slides along the sliding groove (905), keeping the top meshing gear plate (907) always meshing with the side meshing gear plate (908); S4. The side meshing gear disc (908) is meshed with the connecting gear (1007), driving the connecting gear (1007) to rotate synchronously. The rotating connecting gear (1007) drives the cooling fan (1008) to rotate, generating wind in the bottom box (2) and blowing toward the inside of the protection box (4) along the top exhaust port (1010). After the controller (1002) is started, the controller (1002) drives the electric heater (1003) to work. After the electric heater (1003) generates high temperature, the heat is blown toward the surface of the marine valve body (6) along the rotating cooling fan (1008).
