Description
Technical field
The utility model is related to stop valve technical field, particularly relates to a kind of stop valve for preventing oil spilling.
Background technology
At present, the fuel oil in general vehicle fuel tank can form a turgor pressure in the oil gas generated after volatilization in fuel tank
Because fuel consumption reduces the negative pressure that can also form a vacuum in power, fuel tank, bad influence is all easily caused to fuel tank.It is solution
Certainly disadvantages mentioned above, can connect a breather pipe in fuel tank, fuel tank is connected the air in the external world, to avoid producing expansion in fuel tank
The negative pressure of pressure or vacuum.But breather pipe is installed, when the fuel oil in inclination of vehicle or fuel tank is excessive, combustion is but easily caused
Oily leaks and causes danger.
Therefore there is new No. M490997 " oil spill stop valve " Patent Case that the TaiWan, China of on December 1st, 2014 is announced,
It is disclosed：Pearl and a floating plug are rolled including a valve body, one, wherein, the valve body both-end forms an oil gas entrance and an oil gas respectively
A chamber for connecting oil gas entrance and oil gas vent is formed in outlet, the valve body, being formed in the chamber can house the rolling pearl
One pearl groove, the floating plug cunning group in chamber and being situated between located at rolling between pearl and oil gas vent, sit respectively by the chamber, pearl groove and floating plug
Fall within an axle center online, four peripheral wall surfaces of the chamber restrain floating plug along axial line toward polyslip, and the cell wall of the pearl groove allows to roll
Pearl is freely rolled and pushes away tactile floating plug, and the floating plug is sealed via the promotion for rolling pearl or via the promotion of the fluid in overflow to chamber
Close oil gas vent.Whereby, the not good enough problem of traditional oil spill stop valve durability is improved.
There is No. I388459 " oil spill stop valve " Patent Case of invention that the TaiWan, China of on March 11st, 2013 is announced again, its
Disclose：Including：Covered on one pedestal, a rolling member, a hollow valve body and.Pedestal have an oil gas entrance, a supporting part and
The gas channel of one connection oil gas entrance and supporting part；Rolling member bearing is on the supporting part of pedestal；Hollow valve body is mounted on rolling
On moving part, and hollow valve body has a projection；And it is upper lid be then covered on pedestal, it is upper lid have an oil gas vent, a cap bore and
The gas channel of one connection oil gas vent and cap bore.Wherein, an at least perforation is opened up on above-mentioned hollow valve body, the perforation may be used to
Oil gas is emitted into outside fuel tank via oil gas vent, thus the pressure in fuel tank can be reduced, it is ensured that the normal operation of fuel feeding, it is to avoid
Cut the engine.
Case, being capable of self-blocking oil gas vent or valve using a floating plug or a valve body when fuel tank is inclined before above-mentioned patent
Mouthful, the adaptation between floating plug or valve body and oil gas vent or valve port is not good, still results in part permeability, and has potential
Danger, therefore in using upper still preferable not to the utmost.

Specific embodiment
Refer to shown in Fig. 1 and Fig. 2, the utility model embodiment includes a valve seat 1, valve block 2, spheroid 3, top cover 4 and bottom
Lid 5, wherein：
Valve seat 1, is internally provided with a barricade 11 of taper, and the inner area of valve seat 1 is separated out one first air chamber by the barricade 11
12 and one second air chamber 13 (as shown in Figure 3).The lowermost end of the barricade 11 is provided with a recess 14, and the recess 14 is provided with a valve opening
15, the valve opening 15 connection first air chamber 12 and second air chamber 13.The valve seat 1 stretches out and is provided with an air inlet pipe 16, and this enters
The insertion of tracheae 16 is to first air chamber 12.The another outer rim in the valve seat 1 is provided with a fixed part 17, one is opened up on the fixed part 17 and is consolidated
Determine hole 18.
Valve block 2, if entering in first air chamber 12, so as to the moving occlusion valve opening 15.The valve block 2 is integrally formed and is provided with one
Support bar 21, the support bar 21 is stretched in second air chamber 13 by the valve opening 15.An elasticity is arranged on the support bar 21
Element 22, one end of the flexible member 22 is fixed on the support bar 21, separately in being arranged the resilient packing ring of tool on the valve block 2
23.The flexible member 22 is set in the recess 14, by the upward elastic force of the flexible member 22, makes the pad on the valve block 2
Circle 23 elasticity can block the valve opening 15 upwards.
Spheroid 3, it is set in second air chamber 13, and normality promotes the support bar 21 to incline, and makes the pad of the valve block 2
A space (as shown in Figure 3) is produced between circle 23 and the valve opening 15.
Top cover 4, its top for being fixed on the valve seat 1, so as to closed second air chamber 13.The top cover 4 stretches out and is provided with
One escaping pipe 41, the insertion of escaping pipe 41 to second air chamber 13.
Bottom 5, its bottom for being fixed on the valve seat 1, so as to closed first air chamber 12.
When using, as shown in Figures 3 and 4, by the fixing hole 18 on the fixed part 17 of the valve seat 1, using a fixed screw
The appropriate location (not showing in figure) for wearing and being fixed in a car engine room.The escaping pipe 41 of the top cover 4 is connected one again
First body A1, first body A1 are then connected to a canister A, and the air inlet pipe 16 of the valve seat 1 connects one second body B1,
And second body B1 can then be connected to a fuel tank B.So as to alloing the oil gas in fuel tank B via the second body B1 and
The air inlet pipe 16, and be input into first air chamber 12.Promote the support bar 21 to incline using the normality of spheroid 3 again, and make this
Produced space between packing ring 23 and the valve opening 15, is available for oil gas via first air chamber 12 by the space of the valve opening 15
Enter into second air chamber 13.The oil gas entered into second air chamber 13, then can again via the escaping pipe 41, then by this
First body A1 and be delivered to canister A, so as to can be adsorbed to the oil gas after be then exhausted from into air (this be known skill
Art, does not repeat hereby).And the negative pressure of the bulbs of pressure or vacuum in fuel tank B can be reduced, the normal fortune so as to ensuring engine fuel feeding
Make, to avoid cutting the engine or shake.
If as shown in figure 5, during the unexpected run-off the straight of vehicle, and making the valve seat 1 therefore incline as more than 45 degree, now this
The spheroid 3 in second air chamber 13, then depart from the support bar 21, and no longer normality promotes the support bar 21 to incline.When the support
After bar 21 is no longer inclined, then upright state can be reverted to, therefore, using the recovery elastic force of the flexible member 22, this can be made
The closely obstruction of the elasticity of packing ring 23 valve opening 15, to close the space of the valve opening 15, and cuts off the unimpeded of the valve opening 15, therefore can be complete
The full fuel oil for preventing oil gas or spilling in fuel tank B, enters into second air chamber 13, then be transported to via first air chamber 12
In canister A, to avoid overflowing in outside the valve seat 1, so as to danger can be prevented.After the vehicle is through righting, then the spheroid 3
The promotion of the normality support bar 21 can incline again, to open sky produced between the packing ring 23 of the valve block 2 and the valve opening 15
Gap, and maintenance turns on the effect of oil gas.
The utility model embodiment therein is the foregoing is only, it is special when application of the present utility model can not be limited with this
Sharp protection domain, it is all to make simple equivalence changes and replace according to claims of the present utility model and description, all
Claims of the present utility model should be still fallen within to cover in the range of protection.
