[0018] The technical solution in the embodiment of the application is to solve the problem that the actual casting cannot make the water hole to the required size after the upper water hole is too small in the traditional cooling water jacket with an integral structure, which affects the cooling effect of the entire engine water flow field. The patent proposes a structure for accurately adjusting the flow channel of the upper and lower water jackets of the composite cylinder head (corresponding to the communication water hole of the traditional cylinder block water jacket and cylinder head water jacket), and the general idea is as follows:

[0019] Please refer to Figure 1 A plug structure with a water flow adjusting function includes an upper water jacket 10, a plug 20, a lower water jacket 30, and a composite cylinder head 40.

[0020] The upper water jacket 10, the lower water jacket 30, and the composite cylinder head 40 are integrally cast, and the composite cylinder head 40 is provided with a mounting hole for connecting the upper water jacket 10 and the lower water jacket 30. The plug 20 is detachably mounted in the mounting hole, and the plug 20 is provided with a radial adjusting water hole 210.

[0021] ​​The plug 20 is detachably installed in the installation hole of the composite cylinder cover 40. Part of the cooling water from the lower water jacket 30 passes through the adjusting water hole 210 on the plug 20 into the upper water jacket 10. The plug 20 is detachable, and the adjusting water hole 210 can be cleaned to ensure accurate regulation of the water flow and the cooling efficiency of the engine.

[0022] In the above specific embodiments, please refer to Figures 2-4 The plug 20 is provided with a sealing gasket 240 at one end face inside the installation hole. The plug 20 is provided with an installation groove 250 at one end face inside the installation hole, and the sealing gasket 240 is arranged inside the installation groove 250. The sealing gasket 240 is used to seal the end face of the plug 20, and the installation groove 250 is used to install the sealing gasket 240.

[0023] Further, the sealing gasket 240 and the installation groove 250 are both cross-shaped structures, and the cross-shaped sealing gasket 240 has better sealing effect.

[0024] In the specific setting, the plug 20 is provided with an indication mark 230 on the outer end face. The indication mark 230 is used to determine the angle position of the adjusting water hole 210 on the plug 20, so as to ensure that the adjusting water hole 210 on the plug 20 is connected to the upper water jacket 10 and the lower water jacket 30.

[0025] Specifically, the indication mark 230 is a strip groove arranged in parallel with the adjusting water hole 210. By observing the strip groove on the outer end face of the plug 20, the angle position of the adjusting water hole 210 on the plug 20 can be accurately understood.

[0026] In the specific setting, the outer end face is provided with a pyramid hole 220. The plug 20 is provided with external threads, and the installation hole is provided with matching internal threads. A corresponding tool is used to disassemble and assemble the plug 20 by cooperating with the pyramid hole 220. The pyramid hole 220 on the outer end face of the plug 20 is preferably a common regular hexagonal hole.

[0027] In summary, the plug 20 in the plug structure with the adjusting water flow function is detachably installed in the installation hole of the composite cylinder cover 40. Part of the cooling water from the lower water jacket 30 passes through the adjusting water hole 210 on the plug 20 into the upper water jacket 10. The plug 20 is detachable, and the adjusting water hole 210 can be cleaned to ensure accurate regulation of the water flow and the cooling efficiency of the engine.

[0028] It should be pointed out finally that the above embodiments are merely examples for clearly illustrating the present application and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. It is unnecessary and impossible to enumerate all the embodiments. The changes or variations derived therefrom are still within the protection scope of the present application.
