Abstract
A one-way cylinder opening valve suitable for a hydrogen energy handheld torch is provided and includes a valve body, a valve core assembly, a spring, a spring chamber, and a sealing ring. The spring chamber is connected to the valve body, the valve core assembly and the spring are arranged in the spring chamber, a valve body sealing lip is arranged on the valve body, and the sealing lip and the valve core assembly are sealed by means of a principle of compressing a non-metallic material to reach a sealing specific pressure of the non-metallic material, and the spring provides a sealing force for the valve core assembly; the sealing ring is arranged on an outer side of the valve body, so as to ensure sealing between the valve body and a gas cylinder. A through hole is provided in the spring chamber and used as a hydrogen inlet, and a hydrogen intake hole and a central flow channel of a valve core are provided in the valve core assembly. An external force needed to open the cylinder opening valve is greater than a sealing force provided by the spring for the valve core assembly and an upward medium force applied to the valve core assembly in an under-pressure state, hydrogen enters a central through hole in the valve body through the hydrogen inlet, the spring chamber, the hydrogen intake hole and the central flow channel of the valve core, and flows out via the central through hole, so as to realize hydrogen discharging.
