The invention relates to a heat dissipation control valve and a heat dissipation system, the heat dissipation control valve comprises a valve body and a valve rod, the valve body is provided with a valve cavity, a main oil inlet channel, a first working channel, a second working channel and an oil return channel, and the valve rod is movably arranged in the valve cavity to control the main oil inlet channel to communicate with the first working channel or the second working channel through the valve cavity. When the main oil inlet channel communicates with the first working channel, the heat dissipation control valve can drive the hydraulic motor to drive the fan to rotate clockwise, and when the main oil inlet channel communicates with the second working channel, the heat dissipation control valve can drive the hydraulic motor to drive the fan to rotate anticlockwise. The valve body is further provided with an overflow channel capable of being communicated with the main oil inlet channel and the oil return channel, the heat dissipation control valve further comprises an overflow valve, and the overflow valve is arranged on the overflow channel to control on-off of the overflow channel. According to the heat dissipation control valve and the heat dissipation system, the problem that a large amount of dust is accumulated on blades of the fan and even other parts of the heat dissipation system due to long-time working of the fan is solved.
Description
technical field [0001] The application relates to the technical field of construction machinery, and in particular, to a heat dissipation control valve and a heat dissipation system. Background technique [0002] Usually, construction machinery and equipment will generate a lot of heat during the working process. Therefore, it is necessary to use a heat dissipation system to dissipate heat from construction machinery and equipment. The heat dissipation system includes a fan, a hydraulic motor and a heat dissipation control valve. The fan is installed on the output shaft of the hydraulic motor. The heat dissipation control valve is connected to the hydraulic motor for driving the hydraulic motor to rotate. However, long-term operation of the fan will cause a large amount of dust to accumulate on the blades of the fan and even other parts of the cooling system, which in turn causes the cooling effect of the cooling control valve and the cooling system to deteriorate.
