Abstract
The utility model relates to a machine oil passage one-way valve capable of preventing machine oil from flowing back. The machine oil passage one-way valve capable of preventing the machine oil from flowing back comprises a seal plate, a valve body and a shell. The valve body is arranged inside the shell, the seal plate is arranged at the top end of the shell, and the top of the valve body is connected to the center of the seal plate in a riveting mode. A one-way valve is arranged perpendicular to an oil inlet passage of a machine oil pump of an engine. The seal plate is formed by punching of sheet steel, and nylon materials are used for reducing weight of the valve body. The one-way valve is attached closely to the top end face of the shell due to self weight of the valve body and the seal plate, and thus the machine oil above the shell is stopped and can not flow back into an oil sump. The one-way valve is basically arranged in an oil pool, and thus suction of the machine oil by the machine oil pump for the first time is ensured and only weight of the valve body and the seal plate needs overcoming. The machine oil is sealed into the machine oil passage by means of the one-way valve after the machine oil pump is stopped, and can be sucked into a lubricating oil passage rapidly after the machine oil pump is started again.
Description
Technical field
The utility model relates to a kind of Oil passage one-way valve that machine oil refluxes that prevents for the engine motor oil road.
Background technique
The engine lubrication mode generally is divided into gets rid of lubricated two kinds of oil lubrication and forced draught, getting rid of oil lubrication is to utilize disc that the machine oil that splashes in the crankcase is got rid of to oil leab, its feature is as long as engine running will throw away by machine oil, reliable operation, but lubrication pressure is little, so general is used at subminiature motor.Most of motor all can use the lubricated mode of forced draught, oil pump namely is set in lubricating oil path, oil pump is pressed to the lubricating oil path everywhere of motor to the machine oil sucking-off again from oil sump, and this machine oil with certain pressure can guarantee that friction pair is lubricated fully everywhere.But the shortcoming of forced draught lubricating system is when piloting engine at every turn, oil pump can lag behind the time that oil sucks out, motor moved one or two minute often, lubricating oil path does not also have machine oil, longer for oil pump oil suction road especially, the situation that the oil pump mounting point is higher, pump oil is just longer lag time, if at this moment motor continues operation and can not get oil lubricating, will cause dry grinding, cause the wearing and tearing of connecting rod bearing shell, bent axle, piston, serious situation can cause Bearing score, scuffing of cylinder bore.After causing the engine shutdown of this situation; machine oil in the vertical Oil passage will be back in the oil sump; when piloting engine at every turn; oil pump oil suction road is inorganic oil; oil pump just can pump machine oil after need to the air in the chamber, oil suction road is all drained; the long and higher situation in oil pump mounting point in oil pump oil suction road, the pump oil time will be very long.
The model utility content
Technical problem to be solved in the utility model provides a kind of engine lubricating oil that can make and blocks and can not flow back in the oil sump, and machine oil is pumped fast and is fast the Oil passage one-way valve of engine lubrication.
For addressing the above problem, the Oil passage one-way valve that prevents that machine oil from refluxing of the present utility model comprises: sealing plate, valve body and shell; Valve body is located in the shell, and sealing plate is located at the upper end of shell, the top of valve body be riveted on sealing plate central authorities.
This one-way valve is vertically mounted in the engine oil pump oil input channel; Sealing plate is to be formed by the sheet metal punching out, and valve body has adopted nylon material to alleviate its weight.This one-way valve utilized valve body and sealing plate deadweight be close to the shell upper-end surface, like this so that the above machine oil of shell block and can not flow back in the oil sump.The one-way valve position is substantially in oil sump; only need overcome when so just having guaranteed the first oil suction of oil pump valve body and sealing plate just can be with the machine oil sucking-off behind the gravity; utilize one-way valve that machine oil all is sealed in the oil duct after the shutdown, oil pump just can be extracted into oil leab to machine oil soon when again starting.
As the scheme of optimizing, described valve body comprises the center valve rod, is located at the axial flap that arranges of multi-disc of this center stem bottom, and each flap Central Symmetry is distributed on the valve rod of center.
The utility model has positive effect with respect to prior art: get a difficult problem slowly when the Oil passage one-way valve that prevents that machine oil from refluxing of the present utility model has solved engine start on the machine oil, effectively solved motor Bearing score scuffing of cylinder bore and got problem.

Embodiment
See Fig. 1 to 5, the Oil passage one-way valve that machine oil refluxes that prevents of present embodiment comprises: sealing plate 1, valve body 2 and shell 3, valve body 2 are located in the shell 3, and sealing plate 1 is located at the upper end of shell 3, and the top of valve body 2 is riveted on the central authorities of sealing plate 1.
This one-way valve is vertically mounted in the engine oil pump oil input channel, valve body 2 adopts the nylon material manufacturing, in order to alleviate its weight, valve body 2 adopts the mode of rivet hot to link together with sealing plate 1, sealing plate 1 adopts the sheet metal punching out to form, this Oil passage one-way valve has utilized the deadweight of valve body 2 and sealing plate 1 to be close to shell 3 upper-end surfaces, so that the machine oil of shell more than 3 is blocked and can not be flow back in the oil sump.
Described valve body comprises center valve rod 21, is located at the axial flap 22 that arranges of multi-disc of these center valve rod 21 bottoms, and each flap 22 Central Symmetry is distributed on the center valve rod 21.
Described one-way valve mounting point is substantially in oil sump; only need overcome when so just having guaranteed the first oil suction of oil pump just can be with the machine oil sucking-off behind the gravity of valve body 2 and sealing plate 1; utilize one-way valve that machine oil all is sealed in the oil duct after the shutdown, oil pump just can be extracted into oil leab to machine oil soon when again starting.
Claims (2)
1. Oil passage one-way valve that prevents that machine oil from refluxing is characterized in that comprising: sealing plate, valve body and shell; Valve body is located in the shell, and sealing plate is located at the upper end of shell, the top of valve body be riveted on sealing plate central authorities.
2. the Oil passage one-way valve that prevents that machine oil from refluxing according to claim 1 is characterized in that: described valve body comprises the center valve rod, be located at the flap that the multi-disc of this center stem bottom axially arranges, and each flap Central Symmetry is distributed on the valve rod of center.
