Description
The utility model relates to a kind of low-temperature (low temperature) vessel, particularly relates to a kind of cryogenic liquid gas and stores and releasing device.
At present the every profession and trade supply gas adopts the gas cylinder splendid attire mostly, and this mode exists net weight and gross weight than little, and transportation is inconvenient, supply gas pressure shakiness, air feed expense height, shortcoming such as impurity content height in the gas.Chinese patent CN2204369 discloses a kind of multipurpose cryogenic liquid vessel, comprises the liquid-storage device that is made of inside and outside tube, places the valve seat on the urceolus, the suction port that communicates with inner core, be arranged on the transfer gas port on the valve seat, air outlet, vaporization element and supercharging element etc.Though overcome most shortcoming of gas cylinder, but still having deficiency, this device adopts nature heating mode, can not fine adaptive temperature environmental change, use argon gas as argon arc welding machine, if adopt the said vesse splendid attire, during the winter field operation, it is low excessively to discharge gas flow, can not satisfy welding requirements, in addition, the supercharging element uses material many, and efficient is low etc.
It is an expansion chamber that the purpose of this utility model is to provide a kind of pressurized part, the efficient height, and the cryogenic liquid gas that changes that can conform is well stored and releasing device.
The utility model cryogenic liquid gas is stored and releasing device is achieved in that it comprises liquid storage tank, is positioned at the expansion chamber on liquid storage tank top, and is arranged on the input output unit on expansion chamber top.Wherein liquid storage tank is by inner bag, outer courage, be positioned at inside and outside courage place suitable for reading and connect the sealing cover of inside and outside courage, and the insulation reflecting layer that clads on the wall is outside the tank formed, the insulation reflecting layer becomes especially with the multicoating infrared reflecting layer for well, be vacuum layer between the inside and outside courage, have good heat-blocking action; Expansion chamber is connected with outer courage by end opening, the expansion chamber shell that is connected with input output unit suitable for reading, and be arranged on the interior electrothermal device composition of expansion chamber shell, electrothermal device is sealed by an end, the other end and the extraneous heating pipe that communicates, and the heating element that is arranged in the heating pipe constitutes. Input output unit is by the feed liquor outlet passageway, the vaporization passage, and discharge passage and escape way are formed.The feed liquor outlet passageway comprises that its lower end passes the sealing cover of expansion chamber shell and liquid storage tank and stretch into inner bag bottom, and the other end is equipped with the liquid inlet pipe of liquid flowing valve, communicates with liquid inlet pipe and expansion chamber and has the steam outlet pipe of the valve of giving vent to anger.The vaporization passage comprises that the sealing cover that the one end passes expansion chamber shell and liquid storage tank stretches into inner bag top, the generating tube that the other end communicates with expansion chamber, and be installed in regulating valve on the generating tube.The discharge passage is that the sealing cover that an end passes expansion chamber shell and liquid storage tube stretches into inner bag top, and the other end is equipped with the liquid overflow pipe of discharge valve.Escape way comprises that an end communicates with expansion chamber, and the other end is the bursting tube of arm and is installed in Safety valve and pressure gauge on the arm respectively.
For alleviating vibrations, can between inside and outside courage bottom, shockproof carriage be set, also venting can be set on wall of inner container, generally be positioned at the wall of inner container bottom, venting is the stainless steel membrane of thickness far below outer courage thickness.Support also is equipped with in outer courage bottom, is advisable with annular, is convenient to place this device.
The utility model cryogenic liquid gas is stored and the working principle of releasing device is, when this device injects liquid gas, close give vent to anger valve and regulating valve, open liquid flowing valve and discharge valve, the beginning liquid feeding, when liquid spill-way has liquid to overflow, stop liquid feeding, close liquid flowing valve and discharge valve then; Liquid gas and time spent not for a long time are housed in this device, must close liquid flowing valve, give vent to anger valve and discharge valve.The liquid gas of storing in this device is partly vaporized the back in inner bag top, and is entered in the expansion chamber by regulating valve; When gas pressure is higher than safe threshold values, Safety valve will be opened automatically, discharge partly gas, and when air pressure was lower than safe threshold values, Safety valve was closed automatically, and the gas that discharges simultaneously helps keeping this device surrounding environment lower temperature; When using this device air feed, open give vent to anger valve and regulating valve, the liquid gas in the inner bag will be vaporized and enter in the expansion chamber from generating tube in a large number, and exports from the feed liquor mouth of pipe of giving vent to anger by steam outlet pipe.Regulate regulating valve, can change and throughput; And cross low evaporating capacity when not enough when ambient temperature, can utilize the electrothermal device heating, to increase evaporating capacity.
This reality has new type low temperature liquid gas to store and the advantage of releasing device is, one adopts forces heating mode, the fine temperature variation that conforms of energy; Its two pressurized part is an expansion chamber, saves material, the efficient height; Between its three inside and outside courage shockproof carriage is arranged, improved the steadiness of inner bag; Its four heat-insulating property is good, the outer cover intensity height; Be applicable to that storing various cryogenic liquid gas also discharges it vaporization.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
