Abstract
The utility model discloses a self-closed rapid locking-connecting joint and self-closed rapid inserting-connecting joint for a steel cylinder valve. A one-way valve is disposed in the locking-connecting joint; a one-way valve core and a valve seat are disposed in a valve cavity; a compression spring is disposed between the valve seat and the valve core; the locking-connecting joint is mounted on an outer wall of the valve. A inserting-connecting cavity and a valve cavity are orderly disposed in the inserting-connecting joint; a one-way valve core and a valve seat are disposed in a valve cavity; a compression spring is disposed between the valve seat and the valve core. One-way valves are disposed both in the locking-connecting joint and the inserting-connecting joint, which provides the steel cylinder valve with a two-end self-closing sealing function. The utility model adopts rapid joints, so rapid connection between the steel cylinder valve and a pressure-reducing valve is realized. When the inserting-connecting joint is pulled up, the one-way valves perform self-closing sealing of the locking-connecting joint and the inserting-connecting joint to prevent gas leakage. When the inserting-connecting joint is connected, the one-way valve cores in the locking-connecting joint and the inserting-connecting joint push each other to turn on the one-way valve so as to circulate the gas.
