Abstract
The automatic exhaust device for the low-pressure oil circuit of the diesel engine is a functional component of a diesel engine supply system. It is composed of oil cylinder, float, needle valve, valve hole and needle valve base. The needle valve penetrates through the center of the floater and is fixed with the floater, the lower end of the needle valve is located in the center hole of the needle valve base, and the upper end of the needle valve is inserted into the needle valve hole. Because of the buoyancy of the diesel oil, the floater floats upwards to drive the needle valve to close the valve hole. When air enters the oil cylinder, the air is gradually gathered at the upper part of the oil cylinder because of small specific gravity, and the floater falls down along with the descending of the oil level along with the increase of the air, so that the needle valve hole is opened, and the aim of exhausting air is fulfilled.
Description
The utility model relates to the improvement of diesel engine structure and perfect.
In the low pressure oil circuit of diesel engine supply system, because of the pipeline dismounting poorly sealed, sediment bowl discharges water, diesel-oil filter cleaning, reason such as high combustion chamber pressures gas backstreaming when renew cartridge and oil sprayer clamping stagnation more, to enter gas inevitably, these gases then can influence starting, the smoothness of operation of diesel engine, even make it flame-out.So must in time these gases be discharged.Existing technology is that the oil outlet bolt on the oil spout pump head is unscrewed, and uses hand pump pump oil then, and the diesel oil that contains bubble is constantly outflowed, in the diesel oil that flows out till the no bubble.The shortcoming of this method for exhausting is:
1., untimely because be artificial, remedial, when just finding diesel engine fail to start, galloping even auto extinguishing, just stop to handle.
2., time-consuming bothersome, all be manual operation all along.
3., each processing all is upper reaches, ground a slice diesel oil, befouling environment is also wasted diesel oil.
The purpose of this utility model is to lack a kind of novel venting gas appliance that can get rid of the gas in the oil circuit automatically of limit design at these.
The principle of the utility model foundation is: the proportion of gas is less than the proportion of diesel oil; The size that is immersed in the suffered buoyancy of object in the liquid equals the weight of the liquid that it arranges.
Described diesel low-voltage oilway automatic exhaust device at first is a special oil cylinder 6, its feature be filler opening on top, oil outlet is in the bottom.A step is made in position in the cylinder cavity upper middle, sit a pin on the step and cut down base 5, the top that pin cuts down base 5 is provided with a float 4, and the center of float is passed a pin and cut down 3, the lower end that pin cuts down is inserted pin and is cut down base 5, and the pin that the top is inserted in the upper end that pin cuts down cuts down hole 2.
Described pin cuts down base 5 centers has one slightly to be coarser than pin and to cut down 3 hole, and making pin cut down 3, be inserted in wherein can be movable.And around it a plurality of through holes are arranged, diesel oil can be circulated up and down.
It is that a upper end is the elongated garden cylindrical parts of garden awl point that described pin cuts down 3.It is taper holes that the pin that is complementary with it cuts down hole 2, and the aperture of its upper semisection is slightly less than pin and cuts down 3 diameter, and the aperture of its lower semisection is slightly larger than pin and cuts down 3 diameter.Described pin cuts down hole 2 and can directly do on oil cylinder cover, also can make a part separately, is screwed on the oil cylinder cover with the form that is threaded.
Owing to adopt as above technological scheme, the utility model diesel low-voltage oilway automatic exhaust device to have automatic vent and exhaust in time, and advantage such as pollution-free no waste.
Accompanying drawing is the structural representation of diesel low-voltage oilway automatic exhaust device.
Shown in the figure: 1-oil cylinder loam cake, 2-needle valve hole, 3-needle-valve, 4-float, 5-needle-valve base, 6-oil cylinder.
As shown in FIG.: the diesel low-voltage oilway automatic exhaust device is that the diesel engine supply is a functional parts, it is by oil cylinder 6, float 4, needle-valve 3, valve opening 2, the low seat 5 of needle-valve constitutes, needle-valve passes the float center, and and float interfix, the lower end of needle-valve is located in the center hole of needle-valve base, and needle valve hole is inserted in the upper end.Because the buoyancy of diesel oil makes the float come-up, drive needle-valve and will cut down bore closure.When entering air in the oil cylinder, because air specific weight is little, assemble on oil cylinder top gradually, along with air increases, pasta descends, and float just falls, and needle valve hole is opened, and reaches the purpose of exhaust.
