Description
Technical field
The utility model is related to a kind of valve in automobile refuelling systems, more particularly to a kind of refueling control valves.
Background technology
Refueling control valve be mounted on fuel tank roof on, in traditional refueling control valve technology, fluid level control valve it is upper
Portion is equipped with exhaust outlet, and main float is equipped in refueling control valve, and when refueling, the liquid level in fuel tank is gradually increasing fuel tank, liquid
Main float in level control valve also follows liquid level to rise, and the gas of ullage is arranged by the exhaust outlet on fluid level control valve top
Go out, until exhaust outlet is blocked in main float upper surface, tank internal pressure steeply rises and forms jump rifle, the gasoline in fuel tank
Surge is generated in refueling process, after oiling, surge fades away, and the liquid level of fuel tank declines, at this point, main float can be with
It the decline of liquid level and declines rapidly, cause exhaust outlet that can largely be vented suddenly, cause tank pressure uneven, be easy to cause
Gasoline in fuel tank is overflowed from exhaust outlet, meanwhile, main float declines unstable.
Utility model content
For the defects in the prior art, the purpose of this utility model is that solving tank pressure imbalance in the prior art
The technical issues of, a kind of refueling control valve is provided, this control valve is simple in structure, can prevent the leakage of fuel oil, tank pressure is always
Keep balance.
What the purpose of this utility model was realized in：A kind of refueling control valve, including the valve body with accommodating chamber one, institute
It states and exhaust outlet is provided at the top of valve body, the top of the valve body is provided at least one oil inlet air inlet, and the bottom of the valve body is consolidated
Be connected with collet, be placed with several oil inlets on the collet, on the upside of collet support be provided with to have with accommodating chamber and bottom and open
The spool of mouth, collet upside connecting spring one end, the other end of the spring are connect with the top of spool inner wall, the spool
Top has been slidably connected seal assembly, and the top of the seal assembly can block exhaust outlet, and the bottom of seal assembly can be supported
It touches at the top of the inner wall of spool.
During utility model works, when fuel tank refuels, fuel oil enters from the oil inlet on collet in spool, and fuel oil does not add
Man Qian, fuel-steam from exhaust outlet is expelled to canister to recycle after entering valve body from oil inlet air inlet, when the height of oiling
After not crossing oil inlet air inlet, in a large amount of fuel admission valve body, the gravity of seal assembly is more much smaller than spool, seal assembly first on
It is floating, it floats after spool, seal assembly is slided with respect to spool, when the bottom of seal assembly is contradicted at the top of the inner wall of spool, sealing
Component pulls up spool, and seal assembly blocks exhaust outlet, spool under the action of seal assembly pulling force and fuel oil rapidly upward,
Spool with upward inertia force is tightly pressed against on seal assembly, further improves the leakproofness of seal assembly；Exhaust outlet quilt
After sealing, oiling terminates, and the surge in fuel tank fades away, and the fuel level in valve body continuously decreases, and spool declines, sealing group
Part still blocks exhaust outlet, and at the top of the inner wall of spool with the bottom connection of seal assembly after touch, spool band dynamic sealing assembly is fast
Speed declines, at this point, the height of liquid level has fallen to safe altitude, that realizes exhaust outlet ensures tank pressure while unlatching rapidly
Balance, oil leak will not be caused；From just can be seen that above, compared with prior art, the technique effect having is the utility model：
The utility model has the advantages of simple structure and ingenious, better seal is realized by simple structure design, when liquid level drops to peace

Vertical sliding above and below hole；In this design, when fuel tank refuels, fuel oil enters from the oil inlet on collet in spool, and fuel oil does not add
Man Qian, fuel-steam from oil inlet air inlet enter after valve body successively along exhaust outlet, accommodating chamber two and exhaust pipe lead to canister with
It recycles, after the height of oiling there was not oil inlet air inlet, in a large amount of fuel admission valve body, the gravity of seal assembly compares valve
Core is much smaller, and seal assembly first floats, and floats after spool, and when hook hooks spool inner wall, seal assembly pulls up spool,
Seal assembly blocks exhaust outlet, and spool under the action of seal assembly pulling force and fuel oil rapidly upward, tightly press by the top of spool
In the bottom of small sealing element, the leakproofness of seal assembly is further improved；After exhaust outlet is enclosed, oiling terminates, in fuel tank
Surge fades away, and the fuel level in valve body continuously decreases, and spool declines, when hooking hook at the top of spool inner wall, valve
Core ribbon moves small sealing element and big sealing element declines rapidly, at this point, the height of liquid level has fallen to safe altitude, realizes exhaust outlet
The balance of tank pressure is ensured while rapid unlatching, oil leak will not be caused.
In order to further improve the reliability of seal component architecture, the small sealing element and big being integrated of sealing element are set
It puts.
