Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve groups, in particular to a valve group used on a snow sweeper. Background Art

[0002] Snowplows, which are often called snow pushers or snow blowers, are mechanical equipment specially used to clear snow from the ground. They are mainly used in northern regions with heavy snow in cold weather. When heavy snow hinders traffic, snowplows play an important role. Their main function is to remove snow. The valve group on the snowplow is generally used to control the operation of the mechanical parts on the snowplow, and the flow of hydraulic oil in the valve body is used to achieve the movement control of the mechanical parts on the snowplow.

[0003] Reference announcement number CN216812337U is a valve group used on a snowplow, which includes a valve body and a cover; a plurality of heat exchange fins are arranged on the top of the valve body; a temperature sensor is fixed on the valve body; a heat exchange port is arranged on the top of the cover; a fan is rotatably connected in the heat exchange port; a motor is fixed on one side of the heat exchange port; a filter is fixed outside the heat exchange port; a closed cavity is arranged above the heat exchange port; an exhaust pipe is inserted in the closed cavity; a closing device is installed at the bottom of the closed cavity; this valve group isolates the valve body from the outside by setting a cover to prevent the valve from accumulating dust and The heat exchanger and the fan are provided to dissipate the heat from the valve body to ensure the quality of the hydraulic oil in the valve body; and by passing the tail pipe through the closed cavity, when the snowplow is working, if the temperature sensor detects that the hydraulic oil temperature is too low and affects the use, the closed cavity is sealed by the closing device, and the motor is reversed to allow the fan to transfer the heat on the tail pipe to the valve body to ensure the normal operation of the hydraulic oil. Based on the above, it can be seen that although the valve group can be well applied, it is usually not convenient for circulating the oil, which affects the delivery effect of the valve group on the hydraulic oil and often troubles the users.
