Abstract
The utility model relates to a throttling arrangement, set up thin oil station and high -order oil tank advance oil pipe on, be equipped with check valve I on advancing oil pipe, advance oil pipe and go up to set up and supply oil pipe with the parallelly connected bypass of check valve I, the bypass supplies to be equipped with on the oil pipe check valve II, check valve I and check valve II connect to on the contrary, check valve II series connection throttle plate, the throttle plate center is equipped with the orifice. The utility model discloses reduce the oil feed speed that high -order oil tank was stood to the thin oil, make oil return speed be greater than oil feed speed, make oil spill over in high -order oil tank exhaust hole.
Description
Technical field
The utility model relates to blower fan oil supply system, particularly a kind of throttling arrangement for blower fan oil supply system.
Background technique
Due to the oil supply system of blower fan system; probabilistic ash occurs that the oil-servicing facilitiess such as Lubricating-oil Station quit work suddenly; there is a top petrol tank at blower fan system lubrication thin oil station; its function is exactly that after oil pump fault stops, the oil in top petrol tank lubricates by natural pressure the effect playing proterctive equipment to blower fan region of interest.
Existing equipment oil feed line Φ 32, return line Φ 40, and oil feed line has 2kg pressure, return tube does not have pressure, and when top petrol tank oil level reaches fuel tank upper end exhaust port, oil return speed is slower than oil-feed speed, from exhaust port oil spilling.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of throttling arrangement, reduces top petrol tank to the oil-feed speed of Lubricating-oil Station, makes oil return speed be greater than oil-feed speed, oil can not be overflowed at exhaust port.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of throttling arrangement, be arranged on the oil inlet pipe of Lubricating-oil Station and top petrol tank, oil inlet pipe is provided with one-way valve I, oil inlet pipe arranges the bypass fuel supply line in parallel with one-way valve I, bypass fuel supply line is provided with one-way valve II, one-way valve I connects to contrary with one-way valve II's, and one-way valve II connects Rectifier plate, and Rectifier plate center is provided with throttle orifice.
Described orifice diameter is 4-6mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model reduces top petrol tank to the oil-feed speed of Lubricating-oil Station, makes oil return speed be greater than oil-feed speed, oil can not be overflowed at top petrol tank exhaust port.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-Lubricating-oil Station 2-top petrol tank 3-oil inlet pipe 4-one-way valve I5-one-way valve II6-Rectifier plate 7-return tube 8-exhaust port
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of throttling arrangement, be arranged on Lubricating-oil Station 1 with on the oil inlet pipe 3 of top petrol tank 2, oil inlet pipe 3 is provided with one-way valve I4, oil inlet pipe 3 arranges the bypass fuel supply line in parallel with one-way valve I4, and bypass fuel supply line is provided with one-way valve II5, and one-way valve I4 connects to contrary with one-way valve II5's, one-way valve II5 connects Rectifier plate 6, and Rectifier plate 6 center is provided with throttle orifice.Orifice diameter is 4-6mm.
Be only basic principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
