The invention discloses an explosion-proof valve for a liquid hydrogen storage tank. The valve comprises a first valve body, a first flange is fixedly welded to the left side of the first valve body,a second flange is fixedly welded to the right side of the first valve body, a first liquid inlet is formed in the left side of the first valve body, and a first liquid outlet is formed in the right side of the first valve body; and the inner wall, close to the first liquid inlet, of the first valve body is provided with a valve seat, the left side of the valve seat is provided with a first valveplate, a valve rod is fixedly arranged on the right side face of the first valve plate, a supporting block is arranged on the right side of the valve rod in a sleeving mode, and the supporting block is fixedly arranged on the inner wall of the lower side of the first valve body. According to the valve, through the combination between a pressure relief cavity and a pressure relief valve which are in the first valve body, the anti-explosion effect of the valve is better; and then through the first valve plate in the first valve body and a second valve plate in a second valve body, the valve canbe effectively prevented from injecting liquid hydrogen when exploding, liquid hydrogen waste is avoided, and the safety is improved.
Description
technical field [0001] The invention belongs to the technical field of liquid hydrogen storage tanks, in particular to an explosion-proof valve for liquid hydrogen storage tanks. Background technique [0002] Liquid hydrogen is a liquid obtained by cooling hydrogen. It is a colorless, odorless, high-energy, low-temperature liquid fuel. The normal hydrogen boiling point of one atmosphere is 20.37K (-252.78°C), and the freezing point is 13.96K (-259.19°C). The density is 70.85kg / m3. Liquid hydrogen is one of the main storage methods of hydrogen. [0003] At present, liquid hydrogen is mostly stored in storage tanks, and the valves installed on the existing storage tanks only have the functions of cut-off, adjustment, flow diversion, and flow diversion during fluid transportation. During the use of the liquid hydrogen storage tank, the liquid hydrogen inside it will be vaporized due to heat, which will cause the pressure in the storage tank to increase, the gas will expand, a...
