Abstract
The invention discloses an overflow cut-off valve. Under the condition that a fuel tank is positioned at normal air pressure, gas inside the fuel tank exchanges with external gas through a gas outlet hole; under the condition that greater negative air pressure exists inside the fuel tank, the external gas bursts through a rubber assembly to enable each gas inlet channel to be conducted with a pressure-maintaining plastic part inner cavity; the external gas enters the fuel tank through the gas inlet channels. According to the overflow cut-off valve disclosed by the invention, gas outlet channels and the gas inlet channels are separated without mutual influence; the sizes of the gas outlet channels and the gas inlet channels can be respectively designed, so that the gas inlet channels and the gas outlet channels can be suitable for fuel tanks of vehicles with different powers and different sizes. The fuel tanks of the vehicles with the different sizes have little influence on a gas outlet hole in an annular convex rib because the fueling speed of the fuel tank cannot change due to the change of the size of the fuel tank. The gas inlet channels and the rubber assembly commonly influence the gas inlet speed at negative pressure, so that the air inlet speed can be slightly adjusted according to the gas inlet channels and the rubber assembly to meet the requirements on the fuel tanks with the different sizes.
Description
Technical field
The present invention relates to a kind of valve body, especially relate to a kind of overflow cutting valve.
Background technique
Overflow cutting valve is installed on vehicle fuel tank usually, there is following effect: 1) during the vehicle fuel tank oiling, by overflow cutting valve, make vehicle fuel tank and atmosphere that certain passage be arranged; And, after vehicle fuel tank is filled with fuel oil, overflow cutting valve can be closed automatically, prevent that fuel oil from overflowing from overflow cutting valve.2) last importantly when the position of fuel tank changes suddenly (as the vehicle overturning), overflow cutting valve can stop fuel oil to flow out, as on October 17th, 2012, the disclosed patent No. was 201210229757.9, name is called " a kind of overflow cutting valve ", comprises the thin rubber of pressurize working of plastics and pressurize
The periphery of the thin rubber of pressurize is pressed between annular seating and base plate, and in fuel tank normal barometric pressure situation, near the center hole of the thin rubber of pressurize, position is near step, and fuel tank internal gas is by the micro-gap between the thin rubber of pressurize and step and extraneous gas exchange; When fuel tank internal exists in the situation of larger negative air pressure, near the thin rubber center hole of pressurize, position moves down because of the external pressure effect, extraneous gas enters in fuel tank by air inlet duct, when fuel tank internal exists in more atmospheric situation, the thin rubber of pressurize is washed from annular seating by air pressure inside together with the pressurize working of plastics, and the first Returnning spring is in compressive state.
There are the following problems for the overflow cutting valve of this structure: the outlet passageway when gas-entered passageway of relief valve in the normal barometric pressure situation and larger negative air pressure is same passage, and this passage is exactly the gap between the thin rubber of pressurize and miscellaneous part.In the normal barometric pressure situation (during oiling), internal gas is by the micro-gap between the thin rubber of pressurize and step and extraneous gas exchange; What during air inlet, rely on is that the thin rubber distortion of pressurize that negative pressure causes makes passage bigger.The finite deformation amount that micro-gap while giving vent to anger and rubber produce because of pressure has jointly determined that the gas-entered passageway of this relief valve when larger negative air pressure is also smaller, and this valve only is adapted to the fuel tank of small volume.Because the vehicle power size is directly proportional with the fuel tank size, vehicle power is large, and the speed of oil absorption of motor, than very fast, just need to possess larger gas-entered passageway, just can avoid fuel tank to inhale flat problem because negative pressure is excessive.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of overflow cutting valve that is applicable to the different volumes oil tank of vehicle, because of its outlet passageway and gas-entered passageway separately, between two passages, be independent of each other, the size of outlet passageway and gas-entered passageway can be designed respectively, the fuel tank of different capacity size vehicle can be suitable for.
