The marine telescopic spraying nozzle comprises a valve body, the valve body can be fixed to a ship side plate, a water passing hole is formed in the valve body, one end of the water passing hole corresponds to the water inlet end of the valve body, the other end of the water passing hole corresponds to the water outlet end of the valve body, and the water inlet end of the valve body can be connected with a water supply pipeline on a ship; the positioning block is fixed to the water outlet end of the valve body, and a center hole is formed in the middle of the positioning block; the movable rod is slidably located in the center hole, a water passing gap is formed between the outer side wall of the movable rod and the inner side wall of the center hole, a water guide disc is arranged at one end of the movable rod, the peripheral edge of the water guide disc abuts against the end of the positioning block in a sealed mode, and the movable rod extends out under the action of water pressure in the valve body. Water flow in the valve body passes through the water passing gap and is sprayed out under the flow guiding effect of the water guiding disc. The spring is arranged on the outer side of the movable rod in a sleeving mode and controls withdrawing and resetting of the movable rod, the structure is simple, the automatic telescopic water spraying effect can be achieved, and a spraying system is safe and reliable.

    本发明公开了一种船用伸缩式喷淋喷头,其包括:阀体,阀体可固定在船舷板上,阀体的内部设有过水孔且过水孔的一端对应阀体的进水端,另一端对应阀体的出水端,阀体的进水端可与船上的供水管路连接;定位块,定位块固定在阀体的出水端,定位块的中部设有中心孔;活动杆,活动杆滑动位于中心孔内,活动杆的外侧壁与中心孔的内侧壁之间形成过水缝隙,活动杆的一端设有导水盘,导水盘的四周边缘与定位块的端部密封抵接,活动杆在阀体内部水压作用下伸出,阀体内的水流经过所述过水缝隙并在导水盘的导流作用下喷出;弹簧,所述弹簧套设在所述活动杆的外侧并控制活动杆的回撤复位,本发明结构简单,可以实现自动伸缩式喷水效果,喷淋系统安全可靠。
