The utility model discloses a safe automatically-closing gas valve. The safe automatically-closing gas valve comprises an automatically-closing valve body with one end connected with a gas inlet pipe and the other end connected with a gas outlet pipe, the gas inlet pipe is provided with a ball valve, the automatically-closing valve body comprises a valve seat and a valve cover which are connected with each other, and the inside of a cavity formed by the valve seat and the valve cover is provided with a pressure sensing device and a gas outlet pipe opening and closing device which is controlled by the pressure sensing device to move; the gas outlet pipe opening and closing device is coaxial with the gas outlet pipe, and the pressure sensing device is perpendicular with the gas outlet pipe opening and closing device. by arranging the pressure sensing device in the vertically direction and the gas outlet pipe opening and closing device in the horizontal direction coaxial with the gas outlet pipe, the safe automatically-closing gas valve achieves accurate reaction to a gas pressure decreasing close to a preset pressure valve and further enhance the safety coefficient. |
