Self-draining gun seat is a kind of firefighting equipment with simple operation, automatic drainage and anti-freezing function. The structure USES spring to close the outlet and drain the gun seat and the remaining water in the water gun cavity. When opening the sealing mouth of the gun seat to make the water gun work, the water outlet of the gun seat is closed by water pressure compression spring, so the sealing performance is superior and reliable. When closing the sealing mouth of the gun seat makes the water gun stop working, the pressure in the gun seat chamber decreases, and the spring automatically springs off to remove the remaining water in the gun seat and the water gun chamber, thus acting as an antifreeze.
