Abstract
The utility model discloses a kind of fuel tank cap canister with two-way valve, comprise cup-shaped body, the centre bottom of body is provided with a hollow pipe column run through, described hollow pipe column under shed and a bracing wire Spielpassung, body bottom portion is provided with a turnover oil pipe near hollow pipe column place, one-way valve is provided with in turnover oil pipe, one-way valve is equipped with lower steel ball, there is lower spring on lower steel ball top, boil-off gas in fuel tank needs certain pressure just can open steel ball and one-way valve, boil-off gas is drained in fuel tank cap canister, there is certain function preventing fuel tank premature discharge, give certain resistance, when one-way valve opens, gas is easily by valve, and fluid oil not easily passes, when desorption, fresh air enters canister by one-way valve, the fluid oil that may exist can be reclaimed.
Description
Technical field
The utility model relates to auto parts machinery, particularly a kind of fuel tank cap canister with two-way valve on general gasoline engines.
Background technique
Current oil tank of vehicle lid and canister product integration, be applicable to the evaporative emission control system of small gasoline machinery, during mechanical motion work, the inclination, vibration etc. of generation easily cause fuel oil to leak, cause discharge vaporization to exceed standard, and easily cause potential safety hazard.
Model utility content
Problem to be solved in the utility model is to provide a kind of fuel tank cap canister with two-way valve, can have and prevent fuel tank premature discharge and the advantage that fluid oil can be reclaimed.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of fuel tank cap canister with two-way valve, comprise cup-shaped body, the centre bottom of body is provided with a hollow pipe column run through, described hollow pipe column under shed and a bracing wire Spielpassung, lid is stamped on the top of body, the lower edge of lid is provided with vertical clearance gap, communicate with outside, carbon dust is had with hollow pipe column gap-fill in body, carbon dust communicates with the gap of lid, described hollow pipe column top is provided with one-way valve, one-way valve is equipped with steel ball, on upper steel ball, there is upper spring on top, described body bottom portion is provided with a turnover oil pipe near hollow pipe column place, one-way valve is provided with in turnover oil pipe, one-way valve is equipped with lower steel ball, there is lower spring on lower steel ball top.
Preferably, described carbon dust top is from bottom to top provided with nonwovens, upper clapboard successively, and carbon dust bottom is from bottom to top provided with lower clapboard, lower nonwovens successively successively.
Preferably, described bracing wire head is cylinder, and bracing wire tail end is large compared with reservoir port, prevents from dropping off fuel tank.
Preferably, cavity is provided with between described upper clapboard and lid.
After adopting technique scheme, the utility model tool has the following advantages:
Boil-off gas in the utility model fuel tank needs certain pressure just can open steel ball and one-way valve, is drained into by boil-off gas in fuel tank cap canister, has certain function preventing fuel tank premature discharge, gives certain resistance; When one-way valve opens, gas is easily by valve, and fluid oil not easily passes; When desorption, fresh air enters canister by one-way valve, the fluid oil that may exist can be reclaimed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the sectional view under the utility model is in adsorbed state;
Fig. 2 is the sectional view under the utility model is in detachment status;
Fig. 3 is explosive view of the present utility model.
Embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of fuel tank cap canister with two-way valve, comprise cup-shaped body 1, the centre bottom of body 1 is provided with a hollow pipe column run through 14, described hollow pipe column 14 under shed and bracing wire 2 Spielpassung, lid 3 is stamped on the top of body 1, the lower edge of lid 3 is provided with vertical clearance gap, communicate with outside, carbon dust 6 is had with hollow pipe column 14 gap-fill in body 1, carbon dust 6 communicates with the gap of lid 3, described hollow pipe column 14 top is provided with one-way valve 9, one-way valve 9 is equipped with steel ball 11, on upper steel ball 11, there is upper spring 10 on top, be provided with a turnover oil pipe near hollow pipe column 14 place bottom described body 1, one-way valve 9 is provided with in turnover oil pipe, one-way valve 9 is equipped with lower steel ball 13, there is lower spring 12 on lower steel ball 13 top, described carbon dust 6 top is from bottom to top provided with nonwovens 7 successively, upper clapboard 8, carbon dust 6 bottom is from bottom to top provided with lower clapboard 4 successively successively, lower nonwovens 5.Described bracing wire 2 head is cylinder, and bracing wire 2 tail end is large compared with reservoir port, prevents from dropping off fuel tank.Cavity is provided with between described upper clapboard 8 and lid 3.
Advantage of the present utility model: oil gas steam needs could discharge under a certain pressure, when upper steel ball 11 is not opened, upper steel ball 11 has the function obstructing fluid oil to enter product cavity; Even if a little fluid oil enters in product, when engine operation, the passage also by lower steel ball gets back to recovery use in fuel tank.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
