Embodiment Construction
[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] refer to figure 1 , the low-temperature propellant storage tank with a pressure control device proposed by the present invention, the low-temperature propellant storage tank body 1, the low-temperature circulation pump 2, the throttle valve 3, the expander 4, the counterflow casing heat exchanger 5, the exhaust Cooling coil 11 , fluid injection rod 6 and exhaust valve 7 , bulk fluid circulation circuit 8 , high-temperature gas exhaust circuit 9 , throttling refrigeration circuit 10 .
[0037] The low-temperature propellant storage tank 1 includes an inner tank 12 and an outer tank 13. The fluid in the tank is a low-temperature propellant, which is composed of a gas phase and a liquid phase, which can be liquid hydrogen, liquid oxygen or liquid methane. Insulation material is filled between the inner and outer tanks, an...
