Description
Technical field
The utility model relates to a kind of canister not easily blocking solenoid valve.
Background technique
Canister is arranged between petrol tank and motor car engine, canister lumen loading has active carbon, active carbon relies on filtering material and adsorption tube and desorption pipe isolated, the gasoline vapor of active carbon by overflowing in adsorption tube adsorbed gasoline case, the desorption pipe of canister is connected with the intake manifold of motor by solenoid valve.During engine operation, solenoid valve is opened under computer control, and the gasoline vapor in canister and the mixed gas of air are inhaled into engine cylinder combustion by desorption pipe and solenoid valve.After canister uses a period of time, the filtering material in it is easy to breakage, and after breakage, amount of activated charcoal particle enters solenoid valve along desorption pipe, valve core of the electromagnetic valve is blocked and causes closed electromagnetic valve not tight, cause engine start difficulty, especially obvious especially in hot day.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of canister not easily blocking solenoid valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of canister not easily blocking solenoid valve, comprise the tank body that right-hand member is closed, tank inner chamber is left, right-hand member is respectively equipped with filter cloth body, granular active carbon is filled with between two filter cloth bodies, tank body left end is connected with cover, cover center is provided with and is communicated with in tank body, outer air pipe, the screen supporting this filter cloth body is provided with between the filter cloth body of described tank inner chamber left end and cover, described tank body right-hand member interior edge face has some contour cylinders of level for right-hand member filter cloth body of conflicting, tank body right-hand member outer side surface has in connection tank body, adsorption tube outer and positioned opposite and desorption pipe,
The piping filter that described air pipe and desorption pipe outer end are all threaded in a tubular form, this piping filter has step through-hole, the screw that step through-hole comprises vent and is threaded with air pipe or desorption pipe outer end, the radial dimension of screw is greater than the radial dimension of vent, the filter sheet covering in vent is provided with in screw, filter sheet is pressed on the step place of vent and screw by stretching into the air pipe of screw or desorption pipe, the material of the filter sheet in air pipe place piping filter is nonwovens, the material of the filter sheet in desorption pipe place piping filter is Stainless Steel Wire mesh grid, filter sheet circumference is all through bound edge process.
Described piping filter outer side surface is provided with the hatching knurling being convenient to manually pull piping filter.
The beneficial effects of the utility model are: the filter sheet that the utility model is arranged at desorption pipe place, can play the effect stoping activated carbon granule to enter solenoid valve along desorption pipe, solve the problem that closed electromagnetic valve is not tight; The filter sheet arranged at air pipe place can filter out a part of impurity entered in the air of canister, the burden that the filter cloth body alleviating tank inner chamber left end filters, and extends the life-span of canister.People can dismantle piping filter easily, by filter sheet cleaning or replacing.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. tank body; 2. filter cloth body; 3. cover; 4. air pipe; 5. screen; 6. the contour cylinder of level; 7. adsorption tube; 8. desorption pipe; 9. piping filter; 10. filter sheet; 11. hatching knurlings.
Embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of canister not easily blocking solenoid valve as shown in Figure 1, comprise the tank body 1 that right-hand member is closed, tank body 1 inner chamber is left, right-hand member is respectively equipped with filter cloth body 2, granular active carbon is filled with between two filter cloth bodies 2, tank body 1 left end is connected with cover 3, cover 3 center is provided with and is communicated with in tank body 1, outer air pipe 4, the screen 5 supporting this filter cloth body 2 is provided with between the filter cloth body 2 of described tank body 1 inner chamber left end and cover 3, described tank body 1 right-hand member interior edge face has some contour cylinders 6 of level for right-hand member filter cloth body 2 of conflicting, tank body 1 right-hand member outer side surface has in connection tank body 1, adsorption tube 7 outer and positioned opposite and desorption pipe 8,
