Abstract
The utility model provides a novel fuel tank gravity valve which comprises a valve body, a metal disc, a sealing plate and a floater. A flow increasing hole is formed between the metal disc and the sealing plate in a valve body cavity. The diameter of the flow increasing hole is 0.5-1.5mm. When the fuel tank gravity valve is used for oil filling, a lower cavity body is in an opening status, the flow increasing hole is located in a sealed zone between the outside of an upper cavity body sealed zone and the lower cavity of the valve body, and the flow performance of the valve can be effectively improved through the flow increasing hole. After the oil is filled, the lower cavity body is in a sealed status and the flow increasing hole can not cause fuel leakage. The fuel tank gravity valve is simple in structure, not complex in production technology in comparison with a common gravity valve at present and capable of replacing an existing automobile fuel tank gravity valve, enables a fuel tank to release pressure rapidly at the time of oil filling, and avoids the phenomenon of reverse jetting at the time of the oil filling.
Description
Technical field
The utility model relates to the fuel tank of vehicle weight valve, especially relates to a kind of novel fuel case weight valve.
Background technique
Weight valve has another name called Tipping valve, is part indispensable in the fuel tank of vehicle, is the important structure in order to guarantee that the fuel tank of vehicle fuel feeding is unimpeded.The effect of weight valve mainly contains: 1, be used for " breathing " of oil tank system, the pressure in the control fuel tank remains in certain safety range the interior pressure of fuel tank; 2, prevent the excessive oiling of fuel tank; 3, gas in the fuel tank and liquid are played the effect that separates, reduce the leakage rate of fuel oil as far as possible by valve.
Fuel tank after refuel jumping rifle, the pressure height in the fuel tank, but discharge slow, cause tank internal pressure too high and occur refueling and regurgitate easily.
The model utility content
The purpose of this utility model provides a kind of novel fuel tank weight valve, can make the pressure after fuel tank discharges oiling rapidly, avoids refueling the phenomenon of regurgitating.
Novel fuel case weight valve provided by the utility model comprises valve body, metal video disc, diaphragm seal and float; Between endoceliac metal video disc of valve and diaphragm seal, be provided with incremental hole; The diameter in described incremental hole is Φ 0.5mm ~ Φ 1.5mm.
Further, the diameter in described incremental hole is Φ 1mm.
Novel fuel case weight valve provided by the utility model is when refueling, and lower chamber is in opening state, and incremental hole is positioned at the sealing area between the outer and lower chamber of the upper cavity sealing area of valve body, and incremental hole can effectively increase the flow performance of valve.After oiling finished, lower chamber was in sealing state, and incremental Kong Buhui causes fuel leakage.
Novel fuel case weight valve provided by the utility model by on traditional weight valve valve body incremental hole being set, can make fuel tank rapid release pressure when refueling, and avoids refueling the generation of regurgitating phenomenon.The utility model is simple in structure, and common relatively at present weight valve production technology is also uncomplicated, replaceable existing fuel tank of vehicle weight valve.
Description of drawings
Fig. 1 is the section of structure of the novel fuel case weight valve that provides of the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Accompanying drawing is the section of structure of the novel fuel case weight valve that provides of the utility model.As shown in the figure, the novel fuel case weight valve that provides of the utility model comprises valve body 1, metal video disc 2, diaphragm seal 3 and float 4; Be provided with incremental hole 5 between metal video disc 2 in valve body 1 chamber and the diaphragm seal 3; The diameter in described incremental hole 5 is Φ 1mm.
This fuel tank weight valve is when refueling, and lower chamber is in opening state, and incremental hole 5 is positioned at the sealing area between the outer and lower chamber of the upper cavity sealing area of valve body, and incremental hole 5 can effectively increase the flow performance of valve.After oiling finished, lower chamber was in sealing state, and fuel leakage can not caused in incremental hole 5.
The utility model is simple in structure, common relatively at present weight valve production technology is also uncomplicated, replaceable existing fuel tank of vehicle weight valve, the incremental hole 5 of this fuel tank weight valve can make fuel tank rapid release pressure when refueling, and avoid refueling the generation of regurgitating phenomenon.
