Pressure pipe one end is connected on efferent duct, and the other end is connected on the preceding triple valve, the preceding triple valve connect respectively partial pressure pipe,
Heat exchanger and oil guide pipe, the rear triple valve connect heat exchanger, oil guide pipe and oil return pipe respectively, the oil return pipe it is another
End is extended in fuel tank.Oil in oil guide pipe is back in fuel tank after entering heat exchanger cooling from partial pressure pipe through oil return pipe, when
When heat exchanger is abnormal, the oil in oil guide pipe is back in fuel tank from partial pressure pipe into oil guide pipe through oil return pipe.
Further, in addition to a ball valve, the ball valve is arranged in the partial pressure pipe.
Further, in addition to a detection means, oil pressure in the detection means detection efferent duct simultaneously controls ball valve
Open, close and uninterrupted.
Further, the heat exchanger is heat-exchangers of the plate type.
In summary, the utility model is by setting triple valve at the two ends of heat exchanger, and sets two triple valves of connection
Oil guide pipe, so that when heat exchanger occurs abnormal, oil can not be back into fuel tank through partial pressure pipe, oil guide pipe and oil return pipe
Interior, without through heat exchanger, within this time, person skilled can be repaired directly to heat exchanger, without carrying out
Shutdown is handled, it is to avoid shutdown handles brought economic loss, improves production efficiency, practical, pushes away with stronger
Wide meaning.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model paper machine petrol station partial pressure cooling system.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.
As shown in figure 1, a kind of paper machine petrol station partial pressure cooling system that the utility model is provided, is installed in the fuel tank of petrol station
On 10.The petrol station is set for each produced on-site of paper machine by oil pump and provided with oil, described to make when oil pump feed is excessive
Paper machine oil station partial pressure cooling system can mitigate the oil pressure at the scene of being supplied to, and unnecessary oil cooling is but back in fuel tank 10 afterwards.
The paper machine petrol station partial pressure cooling system includes oil pump 20, preceding triple valve 30, heat exchanger 40 and rear triple valve
50, the oil pump 20, preceding triple valve 30, heat exchanger 40, rear triple valve 50 are sequentially connected by pipeline, the preceding triple valve 30
It is connected between rear triple valve 50 by pipeline.The oil pump 20 is connected under the liquid level in fuel tank 10 by pipeline, and described rear three
Port valve 50 is extended in fuel tank 10 by pipeline.
Input pipe 61 and efferent duct 62 are connected with the oil pump 20, described one end of input pipe 61 is connected on oil pump 20,
The other end is extended under the liquid level in fuel tank 10.On one end connection oil pump 20 of the efferent duct 62, other end connection produced on-site
Equipment.A partial pressure pipe 63 is connected on the efferent duct 62, the other end of the partial pressure pipe 63 is connected to the preceding triple valve 30
On, an oil guide pipe 64 is provided between the preceding triple valve 30 and rear triple valve 50, three ends of the preceding triple valve 30 are connected respectively
In partial pressure pipe 63, oil guide pipe 64 and heat exchanger 40.The rear triple valve 50 is extended in fuel tank 10 by oil return pipe 65, described
Three ends of triple valve 50 are connected to oil guide pipe 64, heat exchanger 40 and oil return pipe 65 afterwards.
When the oil pump 20 extracts oil in the fuel tank 10 out, due to the oil pump 20 in the course of the work can frictional heat,
So as to which the oil temperature rise of oil can be caused, therefore, oil need to be carried out can be back to again after cooling processing in case oil.The present embodiment
In, the heat exchanger 40 is heat-exchangers of the plate type, and it has, and heat exchange efficiency is high, heat loss is small, installation is easy to clean and uses
The features such as long lifespan so that, can rapidly and efficiently rate by oil cooling but, it is practical.Ball valve is additionally provided with the partial pressure pipe 63,
Detection means is provided with the efferent duct 62, the detection means is electrically connected at ball valve, and unlatching, the pass of controllable ball valve
The flow for closing and passing through ball valve.
The operation principle of the paper machine petrol station partial pressure cooling system is as follows：Supplied when the detection means detects oil pump 20
When oil pressure toward scene is too high, the ball valve in the partial pressure pipe 63 is opened, and efferent duct 62 is connected with the formation of partial pressure pipe 63, unnecessary
Part oil flow into the partial pressure pipe 63.Now, the preceding triple valve 30 connection partial pressure pipe 63 and heat exchanger 40, it is described after
Triple valve 50 connects heat exchanger 40 and oil return pipe 65, so that, unnecessary part oil carries out heat exchanger 40 from triple valve and carried out
Cooling, triple valve 50 is back in fuel tank 10 from oil return pipe 65 after again after cooling.
When exception, which occurs, in heat exchanger 40 to be repaired, disconnect between the partial pressure pipe 63 and heat exchanger 40
Connection, and the connection between heat exchanger 40 and the oil return pipe 65；Make to form logical between the isocon and the mozzle
Road, the mozzle and the oil return pipe 65 formation path；So that unnecessary part oil is carried out in mozzle from isocon, then
It is back to from oil return pipe 65 in fuel tank 10.Now, technical staff can repair to heat exchanger 40, without carrying out dock
Reason.
In summary, the utility model is by setting triple valve at the two ends of heat exchanger 40, and sets two threeways of connection
The oil guide pipe 64 of valve, so that when heat exchanger 40 occurs abnormal, can be by oil not through partial pressure pipe 63, oil guide pipe 64 and oil return
Pipe 65 is back in fuel tank 10, without through heat exchanger 40, within this time, and person skilled directly can be entered to heat exchanger
Row maintenance, without carrying out shutdown processing, it is to avoid shutdown handles brought economic loss, improves production efficiency, it is practical
Property it is strong, with stronger dissemination.
Preferably one embodiment of the present utility model is the foregoing is only, not to limit the utility model,
All any modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in this reality
Within new protection domain.
