Description
Technical field
The present invention relates to gas-liquid conversion depressurization device, particularly relate to low-temperature container gas-liquid conversion depressurization device.
Background technique
The structure of low-temperature (low temperature) vessel many employings double Shell of prior art; the liquid nitrogen class cryogenic liquide used as refrigeration agent is entered to facilitate filling in the interlayer between two-layer housing; in order to keep the temperature of refrigeration agent; need to add thermal insulation layer again in the outside of the inner housing of low-temperature (low temperature) vessel, such as generally need the polyurethane foam or the pearlife protective layer that install hard additional.Cryogenic liquid storage tank is the jacketed type vacuum insulation pressurized container of a kind of special storage and supply liquefied gas at low temp, is widely used in industrial production, in hospital and daily life.But there is due to cryogenic liquide the hazard properties such as lower boiling point, larger expansibility, stronger hygroscopicity, Strong oxdiative and explosive, because China's Cryo Equipment is started late, add Cryo Equipment operator training less, the safe handling of operator to Cryo Equipment is known little about it, so China often occurs to occur casualty accident during Cryo Equipment uses, cause very large loss to China's manpower and materials.
Summary of the invention
The object of the invention is to, overcome the deficiencies in the prior art part, a kind of low-temperature container gas-liquid conversion depressurization device is provided, its constant-voltage equipment is a kind of pressure equaliser according to dynamics and statics design, set working pressure, this device can realize automatically regulating with the form that gas-liquid is used alternatingly according to the pressure in low-temperature (low temperature) vessel tank.
Low-temperature container gas-liquid conversion depressurization device of the present invention, low-temperature (low temperature) vessel upper end cap, safety valve, relief tube, expands cavity, liquid outlet, suction port, liquid return pipe, suction tude, recurrent canal and volute.In the side of low-temperature (low temperature) vessel upper end cap, relief tube is connected with the form upwards penetrated, the upper end of relief tube reaches above low-temperature (low temperature) vessel upper end cap, the upper end of relief tube is connected with safety valve, the lower end of relief tube is connected to expands cavity, expanding the bottom of cavity is connected with liquid return pipe and recurrent canal, the upper end-hole of liquid return pipe and recurrent canal is connected to expands in cavity, the lower end mouth of liquid return pipe is then arranged on the bottom in Low Temperature Liquid tagma in low-temperature (low temperature) vessel, the recurrent canal arranged in liquid return pipe side, lower end is connected with volute, that is, the upper end of volute is connected with the lower end of recurrent canal, the lower end of volute is connected with the lower end of suction tude, the upper end of suction tude is suction port, suction port is arranged on and expands the side of cavity.
Low-temperature container gas-liquid conversion depressurization device of the present invention, overall structure is simple, installs and easy for operation, and good stability, reliability is high.Use low-temperature container gas-liquid conversion depressurization device of the present invention, its constant-voltage equipment is a kind of pressure equaliser according to dynamics and statics design, set working pressure, this device can realize automatically regulating with the form that gas-liquid is used alternatingly according to the pressure in low-temperature (low temperature) vessel tank.Because the volume ratio after gas-liquid conversion reaches 620:1, as long as so the form that safely and effectively gas can be converted to liquid is transported, just can save the cost of transport in large quantities, if liquid is converted to gas automatically in the process of transport, this situation and can only emptying process be done, can waste resource in large quantities undoubtedly, and low-temperature container gas-liquid conversion depressurization device of the present invention solves this problem preferably.
