For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0019] At present, when medium and large diesel engine electro-driven indicator valves are in use, they cannot automatically carry out pressure relief regulation. It requires staff to manually control and adjust, which leads to low flexibility in its use. Moreover, once the staff cannot discover in time and cannot carry out pressure relief treatment quickly, so it is overly dependent on manual control, which brings inconvenience to the use of the staff.

[0020] In view of this, the present invention provides a marine diesel engine safety valve assembly. Through the cooperation of the main body and the protection device, it can automatically carry out pressure relief work without the need for manual control by the staff when the pressure is too high. Therefore, it can ensure the use safety, reduce the dependence on manpower, and bring convenience to the use of the staff.

[0021] Embodiment 1: As can be seen from Figure 1 、 2 、3 and 4, a marine diesel engine safety valve assembly includes a main body 1. An inner cavity 8 is processed inside the main body 1. The marine diesel engine safety valve assembly further includes: a control device 2, installed above one side of the main body 1; a protection device 3, installed below the side of the main body 1 far from the control device 2. Among them, the control device 2 can control the working state of the marine diesel engine safety valve assembly, and the protection device 3 can automatically carry out pressure relief protection when the internal pressure is too high.

[0022] In the specific implementation process, it is particularly pointed out that the protection device 3 can automatically carry out pressure relief protection when the pressure is too high, and the control device 2 can manually control the use status of the marine diesel engine safety valve assembly.

[0023] Furthermore, a gasket 5 is installed in the bottom groove of the main body 1, and a mounting plate 4 is installed below the outer wall of the main body 1;

[0024] In the specific implementation process, it is particularly noted that the gasket 5 can improve the connection sealing performance between the marine diesel engine safety valve assembly and external equipment, and the mounting plate 4 can improve the connection stability between the marine diesel engine safety valve assembly and external equipment, playing an auxiliary installation role. The connection and installation method between the marine diesel engine safety valve assembly and external equipment is not limited and can be selected according to actual usage requirements, and will not be elaborated here;

[0025] Specifically, when using the marine diesel engine safety valve assembly, first, the staff connects the marine diesel engine safety valve assembly with external equipment, and then it can be put into use. Then, the staff can change the usage state of the marine diesel engine safety valve assembly through the control device 2, and the protection device 3 can automatically carry out pressure relief work to ensure the usage safety.

[0026] Embodiment 2: As can be seen from Figure 1 、 2 and 4, the control device 2 includes: a first inclined tube 201, connected to the upper side of one side of the main body 1; a first cover 202, threadedly connected to the end of the first inclined tube 201; a threaded rod 203, rotatably connected to the inner wall of the first cover 202 through a sealing bearing; a plug plate 204, threadedly connected to the outer wall of the threaded rod 203 and movably connected to the inner wall of the first inclined tube 201; wherein, twisting the threaded rod 203 can drive the plug plate 204 to move along the inner wall of the first inclined tube 201;

[0027] In the specific implementation process, it is particularly noted that twisting the threaded rod 203 can change the position of the plug plate 204, and thus can change the usage state of the marine diesel engine safety valve assembly through the plug plate 204;

[0028] Furthermore, a first sealing gasket 6 that fits the outer wall of the plug plate 204 is installed on the inner wall of the first inclined tube 201, and a second sealing gasket 7 that fits the inner wall of the first inclined tube 201 is installed on the inner wall of the plug plate 204;

[0029] In the specific implementation process, it is particularly noted that the materials of the first sealing gasket 6 and the second sealing gasket 7 are not limited, as long as they meet the usage requirements. The first sealing gasket 6 and the second sealing gasket 7 can improve the connection sealing performance between the plug plate 204 and the first inclined tube 201;

[0030] Specifically, based on the first embodiment above, when it is necessary to change the usage state of the marine diesel engine safety valve assembly, the staff twists the threaded rod 203. At this time, the threaded rod 203 drives the plug plate 204 to move along the inner wall of the first inclined tube 201. As the position of the plug plate 204 changes, the usage state of the marine diesel engine safety valve assembly can be adjusted.

[0031] Embodiment Three: From Figure 1 , 2 and 3, it can be seen that the protection device 3 includes: a second inclined tube 301, connected to the lower side of one side of the main body 1; a second cover 306, threadedly connected to the end of the second inclined tube 301; an inclined rod 302, movably connected to the inner wall of the second cover 306 and movably connected to the inner wall of the second inclined tube 301; a spring 303, sleeved on the outer wall of the inclined rod 302 and fixedly connected to the inner wall of the second cover 306; a cavity 304, processed inside the second inclined tube 301; a cavity 305, processed inside the inclined rod 302; wherein, the inclined rod 302 can move along the inner walls of the second inclined tube 301 and the second cover 306, and at the same time compress the spring 303;

[0032] In the specific implementation process, it is particularly pointed out that a sealing sleeve should be installed at the end of the inclined rod 302, so as to ensure the sealing performance between the inclined rod 302 and the second inclined tube 301, in order to avoid the phenomenon of accidental pressure relief;

[0033] Specifically, based on the first and second embodiments above, when the pressure is too high, the inclined rod 302 moves along the inner wall of the second inclined tube 301 and compresses the spring 303 at the same time. When the inclined rod 302 moves to a certain position, the medium can flow into the cavity 305 inside through the cavity 304 and finally be discharged from the end of the inclined rod 302, thus completing the automatic pressure relief work.
