For reaching above-mentioned purpose, engine water cooling plant of the present utility model includes: an engine, a water pump, an and flow distributing valve.Engine includes the cylinder head that mutually combines, and cylinder block, and cylinder head has a cylinder head water inlet, and cylinder block has a cylinder block water inlet.Flow divider valve includes a valve inlet, one first valve outlet port, reaches one second valve outlet port, and valve inlet is communicated to water pump, and first valve outlet port is communicated to the cylinder block water inlet, and second valve outlet port is communicated to the cylinder head water inlet.Major character of the present utility model is: flow divider valve is the cylinder block water inlet place that directly is locked in cylinder block.
The utility model can more include a leakage barriers, and leakage barriers can be located between the cylinder block water inlet of first valve outlet port of flow divider valve and engine, can prevent the cooling water seepage of above-mentioned two part joints.Above-mentioned leakage barriers can be a pad or other equivalent structural member.
The utility model can more include at least one locking piece, locking piece can be in order to directly to be locked in flow divider valve the cylinder block water inlet place of cylinder block, flow divider valve can be locked on the cylinder block of engine, flow divider valve also can adopt welding, riveted joint or other equivalent means of fixation to be fixed on the cylinder block certainly.Above-mentioned locking piece can be a bolt or other equivalent structural member.
Above-mentioned flow divider valve, and leakage barriers can correspondingly provide at least one through hole respectively, wearing flow divider valve, and the through hole of leakage barriers in regular turn, be locked in the cylinder block water inlet place of cylinder block again for locking piece.
