The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby more removes clear and definite defining so that advantage of the present utility model and feature are easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model made.
Fig. 2 is the cutaway view of the utility model embodiment; Fig. 3, Fig. 4 are the shutoff valve cutaway view under the oil circuit closed condition among the same embodiment; Fig. 5 is the shutoff valve cutaway view under the oil circuit open mode among the same embodiment; Fig. 6 is the structural representation of shutoff valve among the same embodiment.
As Fig. 2-shown in Figure 5, fuel pipe 11 is installed on the fuel tank, and shutoff valve 13 is installed in the fuel pipe inner bottom part, and shutoff valve 13 can move up and down, and is supported by compression spring 12.The head 13a of shutoff valve 13 is spherical, and the outer ring below shutoff valve 13 head 13a is provided with seal groove 15, and seal ring 16 is installed in the seal groove 15, and the valve step 14 of fuel pipe 11 inner belows is a horizontal surface.
As can be seen from the figure, seal ring 16 the outside be provided with two contact disks that outer shape is wing, they contact with valve step 14, make that the applying between shutoff valve 13 and the valve step 14 is more firm.In addition, be provided with contact feet 17, like this, can further improve the contact stabilization between itself and shutoff valve 13 seal grooves 15 bottom surfaces in seal ring 16 bottom surfaces.
In the drawings, symbol of numeral 18 and 28 expression adapter plates, they are installed in fuel pipe 11 bottoms, can prevent that shutoff valve 13 outwards breaks away from.
As shown in Figure 3, Figure 4, fuel tank of vehicle shutoff valve of the present utility model, by the elastic force of compression spring 12, the seal ring 16 outside contact disks that are installed in shutoff valve 13 head 13a below contact with horizontal valve step 14, thus shutoff oiling passage.
As shown in Figure 5, fuel tank of vehicle shutoff valve of the present utility model, in the oiling process, when shutoff valve 13 head 13a were subjected to oiling pressure, seal ring 16 together moved down with shutoff valve 13, thereby opens the oiling passage, and like this, fuel oil can flow in the fuel tank.In addition, because the head 13a of fuel tank of vehicle shutoff valve 13 of the present utility model is spherical, compare with the fuel tank of vehicle shutoff valve of former pyrometric cone head shape, what enlarged further that fuel pipe 11 belows discharge space 11a effectively opens area, makes to the oiling process of fuel tank smooth more.
After oiling is finished, the head 13a of shutoff valve 13 no longer is subjected to oiling pressure, at this moment, elastic force by compression spring 12, shutoff valve can move up, and gets back to the initial position, at this moment, the seal ring 16 outside contact disks that are installed in shutoff valve 13 head 13a below contact with horizontal valve step 14, thus shutoff oiling passage.
In the utility model, the seal ring 16 outside contact disks of fuel tank of vehicle shutoff valve contact with horizontal valve step 14, so, even because of shutoff valve reseting procedure or vehicle traveling process IFO intermediate fuel oil case are impacted, skew in various degree takes place in shutoff valve, also can pass through shutoff valve shutoff oil circuit stably.As can be seen from the figure, the outside of seal ring 16 is provided with two contact disks that outer shape is wing, and they contact with valve step 14, makes that the applying between shutoff valve 13 and the valve step 14 is more firm.
As can be seen from the figure, be provided with contact feet 17, like this, can further improve the contact stabilization between itself and shutoff valve 13 seal grooves 15 bottom surfaces in seal ring 16 bottom surfaces, thus prevent fuel oil from the fuel tank adverse current by seal groove 15 to external leakage.
More than specific embodiment of the present utility model is illustrated; but protection content of the present utility model is not only limited to above embodiment; in the technical field, the common knowledge of a GPRS just can be carried out diversified change in its technology main idea scope under of the present utility model.
