With, connection fuel tank internal and the external world, and then regulating oil tank internal pressure；
Lower valve body 2 is located at 7 top of spring base, and lower valve body 2 connect difference with upper valve body 1 and spring base 7 by buckle respectively
Limit the second cavity and third cavity；
The side of lower valve body 2 is equipped with liquid level window, and liquid level window can be connected to fuel tank；It overturns or tilt angle is larger
When, the fuel oil of fuel tank internal is entered in third cavity by liquid level window；
The first valve block 9 and the first spring 10, the top of the upper end connection upper valve body 1 of the first spring 10 are equipped in second cavity
Portion, the lower end of the first spring 10 connect the upside of the first valve block 9；
First valve block 9 is set between the first spring 10 and lower valve body 2；When normal condition, the first spring 10 is in compression shape
State, and the upper end for the third venthole the first valve block 9 being pressed in lower valve body 2；
The downside of first valve block 9 is equipped with air channel, when so that the first valve block 9 being pressed together with lower valve body 2, therebetween
There are slit spaces, and the air channel can be connected to third venthole, are connected to fuel tank internal with external world's holding；
The second valve block 4, float 5 and second spring 6 are equipped in third cavity, second spring 6 is used to support float 5；
The upper end of the lower end connecting spring seat 7 of second spring 6, second spring 6 connects float 5, the top of float 5 and second
Valve block 4 connects, and the second valve block 4 is set at the third venthole of the inside top of lower valve body 2；
When normal condition, float 5 compresses second spring 6 due to self gravity, is detached from the second valve block 4, third venthole
It fully opens, fuel tank internal can be in communication with the outside；When the top of float 5 is bonded with the second valve block 4, third venthole is closed
It closes, fuel tank internal is not connected to the external world.
Preferably, the inside top of upper valve body 1 is equipped with positioning column 11, and positioning column 11 is prevented for positioning the first spring 10
The dislocation of first spring 10 influences tank internal pressure and adjusts.
In some embodiments of the utility model, the top of lower valve body 2 is equipped with location hole, and the location hole is for installing the
One valve block 9 keeps the installation contraposition of the first valve block 9 accurate.
Optionally, the inside of the outside connection upper valve body 1 of lower valve body 2, the outside that lower valve body 2 is connect with upper valve body 1 is equipped with
Mounting groove, mounting groove can place O-ring seal 3.
Preferably, upper valve body 1 is connected by a snap with lower valve body 2, and O-ring seal is equipped between upper valve body 1 and lower valve body 2
3, it prevents fuel oil from oozing out from upper valve body 1 and 2 junction of lower valve body, causes danger.
In other embodiments of the utility model, one end of the second valve block 4 is connect by buckle with float 5, and second
The other end of valve block 4 is fixedly connected with float 5；Float 5 compresses second spring 6 and one end with the second valve block 4 when normal condition
It is detached from, the lower end of third venthole is opened；When 5 stress of float moves up, one end of the second valve block 4 and the buckle of float 5 connect
It connects, the second valve block 4 is bonded with float 5, and the lower end of third venthole is closed；The other end and the float 5 that the second valve block 4 is arranged are fixed
Connection guarantees to be bonded completely when float 5 moves up with the second valve block 4, and then ensures that third venthole completely closes when overturning.
In use, control valve is connect by upper valve body 1 with fuel tank, entire control valve is mounted on fuel tank.Upper valve body 1 with
By flanged joint between fuel tank, for the fuel tank of different model, the part-structure that need to only change upper valve body 1 can meet installation
It is required that greatly reducing workload, reduce costs.
When group refueling, liquid level reaches design height in fuel tank, and fluid level control valve is in close state, while fuel tank master is logical
Air flue is closed；Refueling process generation petrol vapor quantity is larger, and fuel tank gas passes through between the notch between the first valve block 9 and lower valve body 2
Gap is ventilated outward, trim tank internal and external pressure difference, oily loading pressure rapid increase, oiling resistance cannot cause vapour greatly in time
Oil is accumulated in oil filling pipe, refuels and jump rifle, oiling termination；
Oily loading pressure increases, and inside and outside differential pressure constantly increases, which drives the first compression first upwards of valve block 9
Spring 10 is detached from lower valve body 2, and third venthole fully opens at this time, and fuel tank internal is in communication with the outside, and makes fuel tank external and internal pressure
It is balanced, achievees the effect that regulating oil tank internal pressure；
When normal vehicle operation, oil tank liquid level control valve is closed, and liquid level decline, environment temperature reduces, fuel tank internal is in
Negative pressure, the first spring 10 and fuel tank internal negative pressure collective effect, are bonded the first valve block 9 with lower valve body 2；At this point, outside atmosphere
The slit space and third venthole between the first valve block 9 and lower valve body 2 are passed sequentially through, fuel tank is finally entered, is mended to fuel tank internal
Gas to guarantee that tank internal pressure is normal, and then guarantees vehicle safe driving.
When car ramp traveling or overturning, fuel oil enters third cavity by the liquid level window in lower valve body 2, when liquid level reaches
When to certain altitude, fuel contacts float 5 in third cavity generates buoyancy to float 5；When the buoyancy and second spring 6 are right
When the sum of elastic force that float 5 generates is greater than 5 self gravity of float, float 5 rises and is bonded with the second valve block 4, third venthole
It closes, fuel oil can not be overflowed from third blow vent, avoid the generation of safety accident.
A kind of tank pressure of the utility model, which adjusts and ventilates, integrates overturning control valve, simple and compact for structure, drops significantly
Low cost；By pressure adjust and overturning ventilatory function be integrated in one, can not only regulating oil tank internal pressure, guarantee fuel tank in
Portion's pressure is normal and vehicle safe driving, and can be avoided fuel leakage, causes safety accident；In addition the utility model can
By the design of upper valve body and fuel tank coupling part structure, it is adapted to the fuel tank of different model, is had a wide range of application.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements and retouch, these improvement
It also should be regarded as the protection scope of the utility model with retouching.
