It is promoted.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides a kind of canister desorption solenoid valve, including shell 1, is provided with accommodating chamber, shell in the shell 1
Air inlet pipe 11 and escape pipe 12 are provided on body 1, the air inlet pipe 11 and escape pipe 12 are connected to inside the shell 1, in institute
It states and is provided with partition 2 in accommodating chamber, axial horizontally disposed electromagnetic coil 3 and quiet iron are installed in the side of the partition 2
Core 4, one end of a dynamic iron core 5 is inserted into 3 inside of electromagnetic coil after passing through the through-hole on the partition 2, in the dynamic iron
A compressed spring 6 is provided between core 5 and static iron core 4, one end far from the static iron core 4 of the dynamic iron core 5 is provided with cone
Shape block 51 is provided with a sealing ring 7 in the end of the circular cone 51, and the dynamic iron core 5 can be in the work of the compressed spring 6
With on the lower nozzle that the sealing ring 7 is withstood on to the escape pipe 12;A vertical bar 8, institute are withstood in the top of the circular cone 51
It states vertical bar 8 to be connected on a columned sealing-plug 9, the sealing-plug 9 is installed in a vertical cylinder 10, and the air inlet pipe 11 is pacified
On barrel loaded on the vertical cylinder 10, a reset spring 13 is provided with above the sealing-plug 9;When the sealing ring 7 will
When the ferrule of the escape pipe 12, the sealing-plug 9 seals the air inlet pipe 11;When the sealing ring 7 is far from described
