Abstract
The utility model provides an automatic returned oil air exhaust valve which comprises an automatic exhaust valve and a one-way valve, wherein the automatic exhaust valve and the one-way valve are connected in series, and an air inlet of the one-way valve is connected with an air outlet of the automatic exhaust valve. The automatic returned oil air exhaust valve has the advantages that air contained in returned oil in an engine of an oil consumption meter can be discharged in time to prevent the oil from being discharged and outside air from entering the oil consumption meter, and then damage to the engine from the air is reduced and fuel efficiency is improved. The automatic returned oil air exhaust valve has the advantages of being simple in structure, convenient to maintain, low in machining cost, high in working efficiency and the like.
Description
Technical field
The invention belongs to fuel consumption measurement apparatus field, especially relates to a kind of oil return automatic control pressure vent.
Background technique
Fuel consumption meter is the important tool that detects engine performance, owing to often carrying bubble in motor withdrawing oil secretly, if backflow bubble in oil row do not go out, withdrawing oil is being carried bubble secretly and is being flowed directly into motor and can cause engine failure, therefore even can cause engine misses, solve automatic vent in fuel consumption meter, prevent that oil from flowing out and it is very important to prevent that ambient atmos from entering the problem of fuel consumption meter.
Summary of the invention
The invention provides a kind of oil return automatic control pressure vent, is especially applicable to the exhaust of oil return liquid in fuel consumption meter.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is: a kind of oil return automatic control pressure vent, comprise automatic control pressure vent and one-way valve, described automatic control pressure vent is connected with described one-way valve, and described one-way valve gas access connects described automatic control pressure vent gas outlet.
Described one-way valve is connected with described automatic control pressure vent by oil resistant pipe.Described oil resistant pipe is the resistant to elevated temperatures conduit of oil resistant burn into.
Described automatic control pressure vent is floating-tube type or float-ball type.
Described one-way valve is rise-fall type one-way valve, rotary-open type one-way valve or butterfly one-way valve.
Advantage and good effect that the invention has are: owing to adopting technique scheme, in motor withdrawing oil in fuel consumption meter, contained gas can be discharged in time, can prevent that oil is discharged from, and can prevent that ambient atmos from entering fuel consumption meter, thereby reduced the injury of gas to motor, improved fuel efficiency, had simple in structure, easy to maintenance, processing cost is low, working efficiency advantages of higher.

Fig. 2 is that the invention embodiment is applied in the structural representation in fuel consumption meter
In figure:
1, floating-tube type automatic control pressure vent 2, rise-fall type one-way valve 3, oil resistant pipe
4, fuel consumption meter
Embodiment
The present embodiment provides a kind of oil return automatic control pressure vent, as shown in Figure 1, comprises floating-tube type automatic control pressure vent 1 and rise-fall type one-way valve 2, and rise-fall type one-way valve 2 gas accesses are connected with floating-tube type automatic control pressure vent 1 gas outlet by oil resistant pipe 3.
As shown in Figure 2, the invention can be applied in fuel consumption meter.Oil return automatic control pressure vent is installed on fuel consumption meter 4 tops.
The working procedure of this example: oil return automatic control pressure vent is applied in fuel consumption meter.When in motor, remaining oil is back in fuel consumption meter 4, often carrying bubble secretly, when pasta location comparison in fuel consumption meter 4 is low, gas in oil return can be discharged fuel consumption meter 4 in time by floating-tube type automatic control pressure vent 1, when oil fills up fuel consumption meter 4, floating-tube type automatic control pressure vent 1 cuts out, along with the pressure in fuel consumption meter 4 becomes large pasta, decline, floating-tube type automatic control pressure vent 1 is opened, and the gas in withdrawing oil can be discharged from again.Rise-fall type one-way valve 2 can make the gas in fuel consumption meter 4 discharge, and prevents that extraneous gas from entering in fuel consumption meter.In the present embodiment, contained gas in the motor withdrawing oil in fuel consumption meter 4 can be discharged in time, can prevent that oil is discharged from, and can prevent that ambient atmos from entering fuel consumption meter 4, thereby reduce the injury of gas to motor, improve fuel efficiency.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
