Abstract
The utility model provides a fuel steam valve, which comprises a valve cover, a spring, a valve core component and a valve shell, wherein the valve core component is arranged in the valve shell; the bottom of the valve shell is connected with a conical opening; the conical opening is connected with a pipeline; and the shape of the valve core component is matched with the conical opening. Due to the adoption of a conical sealing form, the sealing contact surface is large, so that the sealing failure probability is lowered effectively, and the reliability of the valve is enhanced greatly.
Description
Technical field
The utility model relates to vehicle fuel control field, specifically is a kind of fuel-steam valve.
Background technique
The fuel-steam valve is the key components and parts of vehicle fuel steam control system, is installed on the fuel tank, and a logical fuel tank, a logical canister, control fuel-steam air pressure and close the oil circuit of fuel oil during to several angle when body sway is in case fuel leakage.Existing valve adopts steel ball usually, relies on the pressure of valve internal to forbid, yet this seal form situation about losing efficacy occurs easily because surface of contact is smaller.
The model utility content
For solving the problems of the technologies described above; The utility model provides a kind of fuel-steam valve; Comprise valve gap, spring, mangetic core assembly and valve casing, said mangetic core assembly is arranged in the said valve casing, and said valve casing bottom is connected with tapered opening; Said tapered opening is connected with pipeline, and said mangetic core assembly has the shape that cooperates with said tapered opening.
Preferably, valve casing and mangetic core assembly are all processed by polyoxymethylene.
Under reset condition, the tapered opening of mangetic core assembly is plugged, and when vapor pressure increased, mangetic core assembly was open, and tapered opening is opened, thereby steam can get into pipeline.
The utility model is owing to adopted the form of cone seal, and sealing contact surface connects greatly, thereby effectively reduces the probability of seal failure, thereby has improved the reliability of valve greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model steam valve.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Referring to Fig. 1; Steam valve comprises valve gap 1, spring 2, mangetic core assembly 3 and valve casing 4, and mangetic core assembly 3 is arranged on valve casing 4 inside, and valve casing 4 bottoms are provided with tapered opening; Be connected with pipeline through the star-pursuing opening; Mangetic core assembly 3 has the shape that cooperates with tapered opening, and valve gap 1 is fastened on the valve casing 4 through four points, and spring 2 is arranged between mangetic core assembly and the valve gap 1.
In valve casing 4, put into mangetic core assembly 3 earlier during installation, put into spring 2 and valve gap 1 again, after just descending, be buckled on the valve casing 4, must not come off with handgrip valve gap 1.Valve gap 1 pressing should be smooth, and 4 all should fasten valve casing 4 fully on the valve gap 1, total member of trying to reverse, and the inside part should rotate flexibly.
Wherein, mangetic core assembly 3 and valve casing 4 are all processed by polyoxymethylene.
