Firefighting bucket water drain valve

Abstract

The invention relates to a firefighting bucket water drain valve which comprises a valve seat, a plurality of guide rods fixed on the valve seat, a valve element fixed on the guide rods, a valve body,a compression spring, a water drain rope connected with the valve body and a motor capable of driving the water drain rope to go up and down, wherein the valve seat is mounted on a water drain opening of a firefighting bucket; the valve body is arranged on the valve element in a sleeving manner and can move along the guide rods; the compression spring is arranged on the guide rods in a sleeving manner and always applies force towards the valve seat to the valve body; the inner walls of the valve body always fits the side walls of the valve element to form sealing; openings are formed in the tops and bottoms of the valve seat and the valve body; the bottom of the valve body can completely cling to the valve seat to form a sealing ring; and the opening in the valve seat is positioned in thesealing ring. The firefighting bucket water drain valve can be repeatedly opened and closed to drain water and is large in water drain quantity, simple in structure, low in cost and convenient to mount; and the electric current required by the motor is lower.

Description

technical field [0001] The invention belongs to the field of fire protection, and in particular relates to a water discharge valve for a fire fighting bucket. Background technique [0002] The fire bucket can be combined with the helicopter to quickly and efficiently fetch water to extinguish the fire. The water outlet of the existing fire bucket is closed and opened with multiple thick ropes. This method can only be opened once, and then closed after the water is drained. After closing, it cannot be closed again. Open. If the valve is installed directly at the water outlet, the general valve can discharge water multiple times, but since the water outlet is located at the bottom of the bucket, the pressure is high, and it takes a lot of force to open the valve. If electric control is used, a larger current is required , higher requirements on power supply. Contents of the invention [0003] The object of the present invention is to provide a water discharge valve for a f...
