outdoor fire hydrant
The present invention relates to an outdoor above-ground fire hydrant installed on the boundary between a road and a sidewalk, and more particularly, to an outdoor above-ground fire hydrant in which pressure (friction) loss due to the flow from inflow to discharge of fire water is improved. An outdoor above-ground fire hydrant according to the present invention includes: a stand pipe including a lower body through which fire water is introduced, an upper body having outlets on both sides through which fire water is discharged, and a middle body connecting the lower body and the upper body; a seat ring installed on the inner surface of a vertical tube of the lower body; an opening/closing valve body for opening and closing the seat ring; a valve rod that is lifted while supporting the opening/closing valve body; and a revolving nut rotatably installed on the upper end of the upper body to elevate the valve rod.
본 발명은 도로와 보도 경계상에 설치되는 옥외 지상식 소화전에 관한 것으로서, 특히 소방용수의 유입에서 토출될 때까지의 유동에 따른 압력(마찰) 손실을 개선한 옥외 지상식 소화전에 관한 것이다.
