Abstract
The invention creatively provides an automatic exhaust valve for returned oil. The automatic exhaust valve for the returned oil comprises an automatic exhaust valve and an one-way valve which are connected in series; an air inlet of the one-way valve is connected with an air outlet of the automatic exhaust valve. The automatic exhaust valve for the returned oil has the beneficial effects that air contained in the returned oil of an engine of a fuel consumption meter can be exhausted timely, thus the oil can be prevented from being discharged, outside air can be prevented from entering the fuel consumption meter, and as a result, the damage of air to the engine is reduced, and the fuel efficiency is raised; the automatic exhaust valve for the returned oil has the advantages of being simple in structure, convenient to repair, small in processing cost, and high in working efficiency.
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 detecting engine performance, owing to often carrying bubble secretly in motor withdrawing oil, if backflow bubble in oil row do not go out, withdrawing oil is entrained with bubble and flows directly into motor and can cause engine failure, even can cause engine misses, therefore solve automatic vent in fuel consumption meter, prevent oil from flowing out and to prevent ambient atmos from entering the problem of fuel consumption meter very important.
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 lift check valve, rotary-open type one-way valve or butterfly one-way valve.
The advantage that the invention has and good effect are: owing to adopting technique scheme, in motor withdrawing oil in fuel consumption meter, contained gas can be discharged in time, oil can be prevented to be discharged, and can prevent ambient atmos from entering fuel consumption meter, thus reduce the injury of gas to motor, improve fuel efficiency, there is structure simple, easy to maintenance, processing cost is low, working efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention embodiment
Fig. 2 is the structural representation that the invention embodiment is applied in fuel consumption meter
In figure:
1, floating-tube type automatic control pressure vent 2, lift check 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 lift check valve 2, and lift check valve 2 gas access is 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 top.
The working procedure of this example: oil return automatic control pressure vent is applied in fuel consumption meter.When oil remaining in motor is back in fuel consumption meter 4, often be entrained with bubble, when the oil surface level in fuel consumption meter 4 is lower, gas in oil return can discharge 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, decline along with the pressure in fuel consumption meter 4 becomes large pasta, floating-tube type automatic control pressure vent 1 is opened, and the gas in withdrawing oil can be discharged again.Lift check valve 2 can make the gas in fuel consumption meter 4 discharge, and prevents extraneous gas from entering in fuel consumption meter.Gas contained in motor withdrawing oil in fuel consumption meter 4 can be discharged in time in the present embodiment, oil can be prevented to be discharged, and can prevent ambient atmos from entering fuel consumption meter 4, thus reduce the injury of gas to motor, improve fuel efficiency.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
