The invention discloses a multifunctional adjustable inflatable automatic trigger valve which comprises a fixing block, a supporting plate is connected to the fixing block, a first cavity, a second cavity and a third cavity are sequentially formed in the fixing block from top to bottom, internal threads are arranged in the inner wall of the third cavity, a flow adjusting mechanism is arranged in the second cavity, and the flow adjusting mechanism is connected with the supporting plate. A water seepage hole communicated with the second cavity is formed in one side of the fixing block, a dredging mechanism is arranged at the water seepage hole, a sleeve is rotationally connected to the upper portion in the fixing block, the sleeve penetrates through the first cavity, the penetrating end of the sleeve is communicated with the second cavity, an inner pipe is movably connected into the sleeve, and an air nozzle is connected to the upper end of the inner pipe; and a driving mechanism for driving the inner pipe to move up and down in the sleeve is arranged in the fixed block. During air inflation, the size of the opening in the second cavity can be adjusted through the flow adjusting mechanism, so that the air flow is adjusted; after inflation is completed, the driving mechanism drives the inner pipe to move into the sleeve, so that the air tap leaves the life buoy, and air in the life buoy is prevented from leaking.
本发明公开了一种多功能可调节的充气式自动触发阀,包括固定块,固定块上连接有支撑板,固定块内由上至下依次设有第一空腔、第二空腔和第三空腔,第三空腔的内壁内设有内螺纹,第二空腔内设有流量调节机构,固定块的一侧开设有与第二空腔连通的渗水孔,渗水孔处设有疏通机构,固定块内的上部转动连接有套管,套管由第一空腔穿过,且穿过端与第二空腔连通,套管内活动连接有内管,内管的上端连接有气嘴,固定块内设有驱动内管在套管内上、下移动的驱动机构。充气时,通过流量调节机构可调整第二空腔内开口的大小,从而实现对空气流量的调节;充气完成后,通过驱动机构驱动内管向套管内移动,从而使气嘴离开救生圈,防止救生圈内的气体泄漏。
