Abstract
The utility model provides a novel oil-filling port one-way valve which comprises a piston, a door, a spring and a one-way valve body. The door is fixedly connected with the one-way valve body. The spring is installed in the piston. The piston and the spring are installed in the door. The oil-filling port one-way valve can be used for reverse exhaust if pressure inside an oil tank is too large and can not be released. Therefore, the pressure inside the oil tank can be released, so that the oil-filling port one-way valve has the function of a safety valve. The novel oil-filling port one-way valve is used for replacing an existing oil-filling port one-way valve of an automobile fuel tank, and when oil is filled, danger caused by the excessively high pressure inside the fuel tank can be effectively avoided.
Description
Technical field
The utility model relates to the automobile valve, especially relates to a kind of novel oil filler one-way cock.
Background technique
The oil filler one-way cock is called for short the ICV valve, is a kind of one-way cock that uses on fuel tank of vehicle.This valve can play effects such as preventing fuel oil is regurgitated, splash in the refueling process of fuel tank.
After fuel tank system has increased the ICV valve, can there be certain risk: if occur extreme high pressure in the fuel tank system, in the time of need opening pressure relief valve on the fuel door and carry out pressure release, because the ICV valve is an one-way cock, can stop gas in the fuel tank housing, to enter oil filling pipe, thereby gas can't be discharged from the pressure relief valve on the fuel door, in this case, overpressure in the fuel tank can make fuel tank face breakneck situations such as blast.
The model utility content
The purpose of this utility model provides a kind of novel oil filler one-way cock, by increasing overvoltage release guard device, can effectively avoid occurring in the fuel tank situation of extreme high pressure.
Novel oil filler one-way cock provided by the utility model comprises piston, door, spring and one-way valve valve body; Door is connected with the one-way valve valve body; Spring is installed in the piston; Piston and spring are installed in the door.
Novel oil filler one-way cock provided by the utility model in use, and is excessive and can't pressure release the time, can carry out inverted ventilating by this oil filler one-way cock as tank internal pressure, and tank internal pressure is released.
Novel oil filler one-way cock provided by the utility model has increased overvoltage release guard device on existing oil filler one-way cock, can realize reverse safe exhaust, makes the oil filler one-way cock possess the function of safety valve.Be used to replace existing vehicle fuel fuel tank filler one-way cock, the too high danger that causes of fuel tank internal pressure in the time of can effectively avoiding refueling.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the structural drawing of at present common oil filler one-way valve.Fig. 2 is the section of structure of the novel oil filler one-way cock that provides of the utility model.As shown in Figure 2, the novel oil filler one-way cock that provides of the utility model comprises piston 1, door 2, spring 3 and one-way valve valve body 4; Door 2 is connected with one-way valve valve body 4; Spring 3 is installed in the piston 1; Piston 1 and spring 3 are installed in the door.
Fig. 3 is the user mode sectional drawing of the novel oil filler one-way cock that provides of the utility model.This oil filler one-way cock in use, and is excessive and can't pressure release the time, can carry out inverted ventilating by this oil filler one-way cock as tank internal pressure, and tank internal pressure is released.
This novel oil filler one-way cock has increased overvoltage release guard device on existing oil filler one-way cock, can realize reverse safe exhaust, makes the oil filler one-way cock possess the function of safety valve.Be used to replace existing vehicle fuel fuel tank filler one-way cock, the too high danger that causes of fuel tank internal pressure in the time of can effectively avoiding refueling.
