Detailed description of the invention
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of oil spill stop valve provided by the invention, comprise valve body 1, valve gap 2, elastic component 3, floating plug body 4 and gas channel 5, described valve body 1 has a cavity and cavity one end open, described valve gap 2 is arranged on opening, the other end of described cavity is also provided with oil gas valve port 6, described oil gas valve port 6 is connected with gas channel 5, described floating plug body 4 is positioned at the cavity of valve body 1, and being supported on described valve gap 2 movably by elastic component 3, described oil gas valve port 6 can be closed or open to described floating plug body 4.
Cavity is positioned at the supporting role of elastic component 3 cock body 4 of floating downward, described valve gap 2 is provided with the through hole passed through for fluid, it is inner that oil vapour or fuel oil can enter into valve body 1 by through hole, according to requirements, during normal traveling, the weight of floating plug body 4 is greater than the elastic force of liquid buoyancy and elastic component 3, so spool does not seal described oil gas valve port 6, oil vapour is automatically discharged fuel tank through oil gas valve port 6 and gas channel 5 and absorbed by carbon canister.When vehicle run-off the straight or when overturning, make fuel tank run-off the straight or inversion, the gravity of floating plug body 4 is less than elastic force and the liquid buoyancy sum of elastic component 3 along the component of valve body 1 axis direction, and oil gas valve port 6 is closed by floating plug body 4, prevents fuel oil from being overflowed by gas channel 5.
Gas channel 5 is connected with Charcoal canister, when the fuel oil of the fuel oil in fuel tank too much or in fuel tank occurs acutely to rock, or fuel tank is not when because of the run-off the straight of vehicle driving up descending, oil spill stop valve is also closed, fuel oil in fuel tank can spill from the oil gas valve port 6 of oil spill stop valve and enter the pipeline of evaporative emissions system by gas channel 5 and result in blockage, the oil vapour in fuel tank is caused not flow through carbon canister, or can carbon canister be flowed directly into from the fuel oil that oil gas valve port 6 spills, the present invention proposes solution, oil cabinet 7 is also provided with between described oil gas valve port 6 and gas channel 5, described oil cabinet 7 is connected with described gas channel 5, by increasing the fuel oil that oil cabinet 7 is spilling, a space cushioned and temporarily store fuel oil is provided, when the fuel oil spilt from oil gas valve port 6 flows in oil cabinet 7, prevent it from entering gas channel 5.
Further scheme, in order to make between floating plug body 4 and oil gas valve port 6 close more reliable, prevent leakage of oil, described oil spill stop valve also comprises valve plug body, described valve plug body comprises valve plug body 9 and connects the connecting wall 10 of valve plug body 9 and valve body 1, described oil gas valve port 6 is positioned on valve plug body 9, the end face of described floating plug body 4 is also provided with floating plug head 11, described valve plug body 9 has the valve plug chamber 12 for holding described floating plug head 11, the axial cross section in described floating plug head 11 and valve plug chamber 12 is trapezoidal, coordinate fixing both convenient, described floating plug head 11 is positioned at valve plug chamber 12 and blocks described oil gas valve port 6.
As a preferred scheme, fuel flow returns conveniently in oil cabinet 7 is in valve body 1, valve body 1 inwall adopts inclined design, namely described connecting wall 10 side that is positioned at oil cabinet 7 is obliquely installed by high step-down to the direction of oil gas valve port 6 from the sidewall of valve body 1, whole connecting wall 10 funnel, is convenient to fuel flow returns.
Be formed with partition wall 8 between described gas channel 5 and oil cabinet 7, described partition wall 8 is provided with air extractor vent 16, and described oil cabinet 7 is connected with described gas channel 5 by air extractor vent 16, forms described oil cabinet 7 by partition wall 8, valve body 1 inwall and connecting wall 10.
During in order to make in fuel tank run-off the straight or topple, oil cabinet 7 temporarily stores more fuel oil, described oil cabinet 7 has certain height, namely keep at a certain distance away as L between described oil gas valve port 6 and partition wall 8, the too little requirement that can not meet oil storage of distance L, can not cushion the leakage of fuel oil; Distance L makes too greatly the volume of fuel tank entirety increase, and takes up room.In the present embodiment, distance L between described oil gas valve port 6 and partition wall 8 is between 5mm-20mm, preferably, between described oil gas valve port 6 and partition wall 8, the distance L at interval is preferably 15mm, distance between described oil gas valve port 6 and air extractor vent 16 should keep maximum as far as possible, adopt in the present embodiment, described air extractor vent 16 is arranged on one end exported away from described gas channel 5 of partition wall 8, time fuel tank is tilted, oil cabinet 7 can store more fuel oil, and the fuel oil that oil gas valve port 6 is overflowed directly can not enter gas channel 5 by air extractor vent 16.
Shown in composition graphs 2, in order to increase the space of oil cabinet 7 further, present invention also offers the second embodiment, described valve plug body 9 is provided with oil-returning structure 13, described oil-returning structure 13 has an annular back leakage groove 14, described fuel return hole 15 is arranged at the bottom of annular back leakage groove 14, the sidewall of described annular back leakage groove 14 is connected by described connecting wall 10 with valve body 1, described oil gas valve port 6 is arranged on described oil-returning structure 13, described oil-returning structure 13 is also provided with at least one fuel return hole 15, described fuel return hole 15 is connected with valve plug chamber 12, the fuel flow returns that described fuel return hole 15 makes to be positioned at oil cabinet 7 is to the cavity of valve body 1 side being provided with floating plug body 4, in the present embodiment, described oil-returning structure 13 is provided with a fuel return hole 15, described fuel return hole 15 is arranged at the bottom of annular back leakage groove 14.
A kind of oil spill stop valve provided by the invention, comprise valve body, valve gap, elastic component, floating plug body and gas channel, described valve body has a cavity and one end open, described valve gap is arranged on opening, the other end of described valve body is also provided with oil gas valve port, described oil gas valve port is connected with gas channel, described floating plug body is positioned at the cavity of valve body, and support with on described valve gap movably by elastic component, described oil gas valve port can be closed or open to floating plug body, also oil cabinet is provided with between described oil gas valve port and gas channel, described oil cabinet is connected with described gas channel by air extractor vent, by increasing oil cabinet between oil gas valve port and gas channel, the fuel oil that oil gas valve port is spilt temporarily is stored in oil cabinet, avoid fuel oil and directly enter gas channel, enter the pipeline of evaporative emissions system by gas channel and result in blockage, or can carbon canister be flowed into, the generation of situation that the oil vapour that doing so avoids in fuel tank can not flow through carbon canister or cannot be absorbed by the activated carbon in carbon canister, both fuel oil was saved, it also avoid the pollution to environment.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
