Abstract
The utility model provides a rollover safety valve, comprising a valve casing, a valve core assembly and a check valve assembly. The valve core assembly and the check valve assembly are arranged inside the valve casing. The check valve assembly is disposed at the upper portion of the valve core assembly. An isolation part is arranged between the check valve assembly and the valve core assembly and is provided with an opening. The valve core assembly is provided with a projecting part matched with the opening. The rollover safety valve of the utility model can guarantee pressure balance in an oil tank, so as to avoid accidents which may be caused due to too high or too low pressure of the oil tank, and also guarantee that fuel oil in the oil tank is not leaked when a car accident occurs.
Description
Technical field
The utility model relates to the auto parts and components field, specifically, relates to a kind of overturning safety valve.
Background technique
Unimpeded in order to guarantee the automotive oil tank fuel feeding, fuel tank is provided with valve body, and valve body is made up of valve casing and spool usually; Can guarantee the pressure balance in the fuel tank, meet accident, for example occur turning on one's side when perhaps overturning fully but work as automobile; Fuel oil in the automotive oil tank possibly leak, and then causes on fire even blast, causes great potential safety hazard; Can cause the person and property loss when serious; Thereby need a kind of valve body, and can guarantee the pressure balance in the automotive oil tank, can, automobile avoid fuel leakage when meeting accident again.
The model utility content
The utility model provides a kind of new automobile overturning safety valve, and this safety valve has adopted the upset containment measures, makes automobile when meeting accident upset, guarantees that automotive oil tank can not leak.
The purpose of the utility model can take following method to realize:
A kind of overturning safety valve; Comprise valve casing, mangetic core assembly and check valve assembly; It is inner that said mangetic core assembly and said check valve assembly are arranged on said valve casing, and said check valve assembly is arranged on the top of said mangetic core assembly, between said check valve assembly and said mangetic core assembly, is provided with the isolation part; Said isolation part is provided with opening, and said mangetic core assembly has the lug boss that is complementary with said opening.
Wherein, the valve casing bottom of this safety valve is assemblied in the fuel tank the inside, through rubber washer and fuel tank sealing, guarantees air tight oil-proof.This safety valve the inside includes a mangetic core assembly, a check valve assembly.The mangetic core assembly below is provided with the bottom stage clip; Reason owing to gravity own; The bottom stage clip contacts with lower cover, and is generally, very little to the gas flow of the last flow direction in the fuel tank; When tank pressure reached certain pressure, mangetic core assembly can be bounced owing to receive the pressure of fuel tank internal.The check valve assembly on top under normal circumstances compresses ring-like rubber ring owing to the elastic force that receives the top stage clip, reaches seal action, and the gas that outwards flows to goes out by sealing and can't outflow at this.When tank internal pressure acquires a certain degree, one-way valve opens, gas flows out.When the anti-turnback of overturning safety valve, mangetic core assembly since gravity former thus with the V-type mouth (being sealed and matched) of valve casing top head by small valve core head and V-type mouth at this moment, no matter be that gas or liquid all can't leak.When external pressure during greater than tank internal pressure; When pressure difference reaches a certain amount of, the sealing film of check valve assembly is opened, and gas flows to fuel tank internal by the outside; At this moment, gas is gone into fuel tank internal via the flow through logical phase orifice flow in center of small valve core of mangetic core assembly of check valve assembly.
The utility model owing to adopted above setting; Make this safety valve can guarantee the pressure balance in the fuel tank; Make fuel tank can be because of pressure excessive or too small meeting accident, can guarantee that again automobile fuel oil in the fuel tank when something unexpected happened can not leak.
Description of drawings
Fig. 1 is the overall schematic of the utility model overturning safety valve;
Fig. 2 is the schematic representation of the utility model overturning safety valve mangetic core assembly;
Fig. 3 is the schematic representation of the utility model check valve assembly.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Referring to accompanying drawing 1-3, this overturning safety valve comprises valve casing 4, mangetic core assembly and check valve assembly, and mangetic core assembly and check valve assembly are arranged on valve casing 4 inside.Wherein, be provided with valve gap 7, be provided with lower cover 1, be provided with rubber washer 5 in valve casing 4 and fuel tank cooperation place, and above the cooperation place, be provided with housing 6 in the bottom of valve casing 4 on the top of valve casing 4.Mangetic core assembly comprises valve core 3, bottom stage clip 2, small valve core body 12, small valve core seat 13 and rubber stopper 14; Small valve core body 12 is arranged on the inside of valve core 3; And between small valve core body 12 and small valve core seat 13, be provided with blocked part 15; Bottom stage clip 2 is arranged between small valve core seat 13 and the lower cover 1, and small valve core 12 tops are provided with lug boss.Between mangetic core assembly and check valve assembly, be provided with the isolation part, the isolation part is provided with opening, and the lug boss on the small valve core 12 and this opening are complementary.
Check valve assembly is arranged on the top, isolation part, comprises the ring-shaped rubber packing ring 8 that is arranged on the top, isolation part, the upper valve base 9 that is arranged on ring-shaped rubber packing ring 8 tops, and upper valve base 9 is provided with sealing film 11 and exists, and the top of upper valve base 9 is provided with top stage clip 10.
Because gravity own, bottom compression valve spring 2 contacts with lower cover 1, and is generally very little to the gas flow of the last flow direction in the fuel tank, and when tank pressure reached certain pressure, mangetic core assembly can be bounced owing to receive the pressure of fuel tank internal.The check valve assembly on top under normal circumstances compresses ring-like rubber ring 8 owing to the elastic force that receives top stage clip 10, reaches seal action, and the gas that outwards flows to goes out by sealing and can't outflow at this.When tank internal pressure acquires a certain degree, one-way valve opens, gas flows out.When the anti-turnback of overturning safety valve, mangetic core assembly since gravity former thus with the V-type mouth (being sealed and matched) of valve casing top head by small valve core head and V-type mouth at this moment, no matter be that gas or liquid all can't leak.When external pressure during greater than tank internal pressure; When pressure difference reaches a certain amount of, the sealing film of check valve assembly is opened, and gas flows to fuel tank internal by the outside; At this moment, gas is gone into fuel tank internal via the flow through logical phase orifice flow in center of small valve core of mangetic core assembly of check valve assembly.
