It is strong to hit ability.
Preferably, cold insulation tank wall is equipped with cold insulation layer.Cold insulation layer increases the cold insulation of cold insulation tank body
Effect.
Preferably, closing cylinder lower end surface upper air-vent edge is equipped with the downwardly convex sealing bulge loop of a circle, seal disc is tight
Mi Gai is closed on sealing bulge loop.The setting of sealing bulge loop increases seal disc to the sealing effect of gas vent.
Preferably, gas vent, seal disc, exhaust pipe are coaxially disposed, the diameter of seal disc be greater than the diameter of gas vent and
Less than the internal diameter of exhaust pipe.This structure setting is convenient for exhaust.
Preferably, being equipped with installation on seal disc upper surface and with spring corresponding position is pulled on dsah-pot lower surface
Ring pulls both ends of the spring to be separately mounted in two mounting rings.Both ends of the spring is pulled to be mounted in mounting ring, installation is steady reliable.
Compared with prior art, the beneficial effects of the present invention are: cold insulation tank is also not susceptible to explosion now even if a leak occurs
As effectively preventing explosion and being damaged to the person and property.
