Abstract
An oil pump automatic exhaust system comprises a pumping device and an oil storage tank. The pumping device is communicated with the oil storage tank through a pipeline. The pipeline is provided with a first switch valve, a second switch valve and an air inlet valve, the air inlet valve is placed between the first switch valve and the second switch valve, and the air inlet valve is higher than any one of the first switch valve and the second switch valve. The top of the oil storage tank is provided with an exhaust pipe which is provided with an exhaust valve. After the pumping device stops working, firstly, the first switch valve and the second switch valve are opened to enable the pipeline between the first switch valve and the second switch to be emptied, and then the air inlet valve and the exhaust valve on the exhaust pipe are opened, so that oil inside oil channels can flow back into the oil storage tank quickly under the effect of gravity.
Description
Technical field
The utility model relates to the vent systems on the pump oil pipe line.
Background technique
In the oil circuit pumping system, after pumping finished, because the existence of the negative pressure of oil circuit inside, the oil require in the oil circuit was through could all flowing back in the oil storage tank for a long time.Such situation can not produce larger trouble summer, just easily rise the oil circuit bursting by freezing bad in winter.
The model utility content
The purpose of this utility model provides a kind of oil pump automatic exhaust system of automatic oil return.
The technical solution adopted in the utility model is:
The oil pump automatic exhaust system, comprise pumping installations, oil storage tank, between pumping installations and oil storage tank, pass through pipeline connection, be provided with the first switch valve, second switch valve and suction valve at pipeline, described suction valve is between the first switch valve and second switch valve, and the height of described suction valve is higher than in the first switch valve and the second switch valve any one, is provided with outlet pipe at the top of described oil storage tank, at outlet pipe outlet valve is installed.
The height of described the first switch valve and second switch valve equates.
The height of described the first switch valve is lower than the height of second switch valve.
After pumping installations quits work, first the first switch valve and second switch valve are opened, make the pipeline evacuation between the first switch valve, the second switch valve, then open the outlet valve on suction valve and the outlet pipe, so just can make oil in the oil circuit by very fast being back in the oil storage tank of Action of Gravity Field.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described oil pump automatic exhaust system of the utility model embodiment.
Embodiment
As shown in Figure 1, the described oil pump automatic exhaust system of the utility model embodiment, comprise pumping installations 1, oil storage tank 2, between pumping installations 1 and oil storage tank 2, pass through pipeline connection, be provided with the first switch valve 4, second switch valve 3 and suction valve 5 at pipeline, described suction valve 5 is between the first switch valve and 4 second switch valves 3, and the height of described suction valve 5 is higher than in the first switch valve 4 and the second switch valve 3 any one, be provided with outlet pipe 7 at the top of described oil storage tank 2, at outlet pipe 7 outlet valve 6 be installed.
The height of described the first switch valve 4 and second switch valve 3 equates.
After pumping installations quits work, first the first switch valve and second switch valve are opened, make the pipeline evacuation between the first switch valve, the second switch valve, then open the outlet valve on suction valve and the outlet pipe, so just can make oil in the oil circuit by very fast being back in the oil storage tank of Action of Gravity Field.
