Description
Technical field
The utility model belongs to breather valve field, is related to bonnet reassembling type breather valve.
Background technique
Automobile breather valve is the important accessory that air pressure balance is maintained on automobile, and effect is to make automotive interior and big gas phase
Logical, when gas compartment pressure rise is more than setting value, gas opens the diaphragm seal in breather valve at this time, and gas is discharged out of tank,
Pressure is set not continue to increase.This is the general principles of breather valve, currently, the bonnet and valve body on breather valve use the side of punching press
Formula realizes connection, and spring and diaphragm seal are located in bonnet, therefore spring and diaphragm seal can not take out after installation, accordingly
The cracking pressure of breather valve can not also be adjusted, therefore single breather valve is merely able to correspond to a kind of cracking pressure, applicability
Poor, therefore, it is necessary to be innovated and improved for current breather valve.
