ABSTRACT:
A safety exhaust valve equipped spray gun including a safety exhaust valve provided on the bottle cover above the bottle connecting portion for maintaining air pressure transmitted into the bottle body through an air induction hole within a limited range, by providing a steel ball which is removed from an air exhaust when the pressure exceeds the limited range so that excessive air pressure is exhausted through an exhausted hole and the inner pressure is constantly kept within the limited range. A pressure stabilizing bolt is provided on the air induction hole of the nozzle so that spraying is effectively achieved by providing a fine spraying effect. By means of this arrangement, the spray gun of the present invention insures against explosion and provides a maximum security effect and is practical for both high pressure and low pressure application.
