Description
Technical field
The utility model relates to a kind of novel cooling valve groups.
Background technique
Currently, each mechanism action of engineering machinery is that control completion is carried out by hydraulic system, and the oil liquid temperature in hydraulic system
Degree meeting random device runing time is stepped up, and especially in the weather of summer high-temperature, hydraulic system works long hours, if oil liquid temperature
Sealing element aging will be caused by spending height, and part accessory is influenced to break down by high temperature, while can also reduce the use of related accessory
Service life.It is general at present to be cooled down using being rotated by driven by engine fan, no matter system oil liquid temperature is low temperature or high temperature,
As long as machine operation, fan works, and fan coolling is also carried out in low temperature for oil liquid temperature, oil temperature is too low to will affect work
Efficiency also increases unnecessary energy consumption, and another aspect engine only has a kind of steering, and the dust on cooler cannot be automatically clear
Reason, with the accumulation of dust on cooler, influences cooling effect, also will increase energy consumption.
Utility model content
The purpose of the utility model is to overcome defect of the existing technology, provide that a kind of structure is simple, low energy consumption, safety
The good novel cooling valve group of property.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel cooling valve group, including valve group
Ontology, proportional pressure control valve, hydraulic control direction valve and solenoid valve, the proportional pressure control valve, hydraulic control direction valve and solenoid valve are arranged in valve
On group ontology, the hydraulic control direction valve includes the first hydraulic control direction valve and the second hydraulic control direction valve；The valve group ontology is equipped with
Oil inlet P, the first actuator port A and the second actuator port B, the oil inlet P are connected to solenoid valve, the solenoid valve respectively with
First hydraulic control direction valve and the connection of the second hydraulic control direction valve；The first actuator port A and the second actuator port B respectively with fan
The oil outlet of motor is connected；It is described for control fan motor rotation proportional pressure control valve respectively with the first hydraulic control direction valve and
The connection of second hydraulic control direction valve.
It further include the range of regulation of the proportional pressure control valve are as follows: 0-205Bar, current range are as follows: 0-550mA.
The utility model has the beneficial effects that the utility model solves defect present in background technique, pass through solenoid valve
Positive and negative rotation of motor is realized in cooperation with 2 pilot operated directional control valves, and when motor main story drives fan coolling oil liquid, and motor drives when inverting
Fan blows away the dust on cooler, realizes automatic cleaning dust；Proportional pressure control valve can be controlled according to the height of oil liquid temperature
The velocity of rotation of fan when oil liquid high temperature, gives proportional pressure control valve feedback signal, and proportioning valve is closed, fan high speed operation, fast prompt drop
Low oil liquid temperature is reduced to certain temperature, gives proportional pressure control valve feedback signal, and proportioning valve is opened, and pressure oil overflows by ratio
Valve off-load is flowed, stopping fan rotation can feed back corresponding signal to proportional pressure control valve according to the different temperatures of oil liquid, and then control
Pressing pressure oil enters the flow of motor, reaches control fan velocity of rotation, so as to play energy-saving effect.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the schematic view of the front view of the preferred embodiment of the utility model；
Fig. 2 is the overlooking structure diagram of the preferred embodiment of the utility model；
Fig. 3 is the oil circuit relationship connection schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1-3, a kind of novel cooling valve group, including valve group ontology 1, proportional pressure control valve 2,3 and of hydraulic control direction valve
Solenoid valve 4, the proportional pressure control valve 2, hydraulic control direction valve 3 and solenoid valve 4 are arranged on valve group ontology 1, the hydraulic control direction valve 3
Including the first hydraulic control direction valve 301 and the second hydraulic control direction valve 302；The valve group ontology 1 is equipped with oil inlet P, the first work
Hydraulic fluid port A and the second actuator port B, the oil inlet P are connected to solenoid valve 4, the solenoid valve 4 respectively with the first hydraulic control direction valve
301 and second hydraulic control direction valve 302 connect；The first actuator port A and the second actuator port B respectively with fan motor 5
Oil outlet is connected.The pressure oil for pumping output enters from the oil inlet P of cooling valve group, reaches solenoid valve 4, and solenoid valve 4 executes the
The commutation action of one hydraulic control direction valve 301 and the second hydraulic control direction valve 302, the first actuator port A and the second actuator port B and wind
Fan 5 oil inlet and outlet of motor connects, and fan motor 5 can be achieved in the commutation between two hydraulic control direction valves that the commutation of solenoid valve 4 executes
Positive and negative rotation.Liquid controlled reversing valve opening pressure range: 11 ± 2Bar reaches certain pressure and realizes commutation.
For control the proportional pressure control valve 2 of fan motor velocity of rotation respectively with the first hydraulic control direction valve 301 and the second liquid
Direction valve 302 is controlled to connect.Proportional pressure control valve 2 can according to detection oil liquid temperature sensor feedback come signal control fan turn
Dynamic speed, fan work when oil liquid temperature is high, oil liquid temperature are reduced to certain temperature, give proportional pressure control valve feedback signal, pressure
Power oil passes through 2 off-load of proportional pressure control valve, and stopping fan rotation is fed back when temperature rises to certain temperature to proportional pressure control valve 2
Signal, pressure oil enter motor, fan rotation.Proportional pressure control valve 2 can play energy-saving effect.Proportional pressure control valve range of regulation: 0-
205Bar, current range: 0-550mA.
The technical solution of the utility model is to provide a kind of cooling valve group, and to fan motor 5 for pressure oil, motor drives wind
Fan rotation, by control fan velocity of rotation to solve liquid oil temperature in hydraulic system excessively high, the too fast problem of temperature rise, when high temperature
Fan work, fan stops working when low temperature, to reduce mechanical disorder, improves service life.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With novel.By the utility model the obvious changes or variations extended out of spirit still in the utility model protection
Among range.
