Abstract
The utility model discloses a spigot and socket type heat insulating drawbar support for a cold shield of a cryogenic vessel. The support comprises a casing, a cold shield and drawbars. A hollow stainless steel tube section is arranged in the middle of the drawbar; a lifting lug is arranged on the inner wall of the casing, a fixing hole is formed on the cold shield and has the diameter larger than the diameter of the drawbar, and the drawbar passes through the fixing hole on the cold shield and has the end thereof fixedly connected with the lifting lug on the inner wall of the casing; and the drawbars on the two sides of the cold shield are both coated with an inner heat insulating cover and an outer heat insulating cover, and the front end of the outer heat insulating cover is provided with an outer convex ring platform, passes through the gap between the drawbar and the fixing hole and is inserted into an inner concave step on the end surface of the inner heat insulating cover. The spigot and socket type heat insulating drawbar support is suitable for fixing the cold shield of a cryogenic liquid (such as liquid helium and liquid argon) storage vessel; has the effect of drawbars and has heat insulating effect; and has the advantages of convenience for manufacturing and installation, and so on. The spigot and socket type heat insulating drawbar support has already been used on the heat insulated support of the cold shield of a built-in cryocondensation pump cryogenic temperature distribution valve chest of a large-sized superconducting tokamak experimental nuclear fusion device EAST (experimental advanced superconducting tokamak), with an ideal heat insulating effect.
Description
Technical field:
The utility model relates to the fixing of the cold screen of a kind of low-temperature (low temperature) vessel, and the linkage structure of cold screen of low-temperature (low temperature) vessel and pull bar.
Background technique:
Being in the fixing of the cold screen of 80K cryogenic liquide storage tank, is to adopt thin-wall stainless steel making pull bar and storage tank shell to fix traditionally, causes a large amount of loss of refrigeration capacity of the cold screen of 80K, if tie-strut is fixing undesirable, also can make storage tank shell dewfall even frosting,
Do not reach desirable insulation effect.
The model utility content:
The purpose of this utility model is the loss of refrigeration capacity when reducing the cold screen of fixing 80K, provides to make simply, easy for installation, and the adiabatic pull bar of the cold screen spigot and socket type of the low-temperature (low temperature) vessel that using effect is good again supports.
The technical solution of the utility model is as follows:
The adiabatic pull bar of the cold screen spigot and socket type of low-temperature (low temperature) vessel supports, and includes shell, cold screen, it is characterized in that also including pull bar, is hollow stainless steel pipeline section in the middle of the described pull bar; Described outer casing inner wall has hanger, on the described cold screen fixed hole is arranged, and the fixed hole diameter is greater than the pull bar diameter, and pull bar passes the fixed hole on the cold screen, fixedlys connected with nut with the hanger on the outer casing inner wall in its end; The pull bar of described cold screen both sides is coated with interior jacket, outer jacket outward respectively, and described interior jacket is between hanger and cold screen, and it is inboard that outer jacket bag is positioned at cold screen; The front end of described outer jacket has outer bulge loop platform, pass the gap between pull bar and the fixed hole and be plugged in the indent step on the jacket end face; The engaged at end of described outer jacket has nut, and described nut is pressed on the outer jacket by pull bar.
The adiabatic pull bar of described cold screen spigot and socket type supports, and it is characterized in that described pull bar two ends are the stainless steel threaded stem, and described stainless steel threaded stem is welded to connect with the hollow stainless steel pipeline section of centre.
The adiabatic pull bar of described cold screen spigot and socket type supports, and it is characterized in that adopting between described hanger and the pull bar Placement to be: pull bar perforation is arranged in the middle of the hanger, be used for fixing pull bar, hanger places between nut and the pull bar to compress with nut and is connected.
Thereby the inside and outside jacket of spigot and socket type is clipped in the middle the cold screen of 80K and plays adiabatic and the fixedly effect of the cold screen of 80K.
The utility model is mainly used on the fixing of low temperature clack box, the cold screen of low temperature storage tank, one end and cabinet shell are fixed, the other end nut check, the cold screen of 80K is between the spigot and socket type jacket does not contact, thereby it is fixing but also reach the desirable insulation effect of cold screen not only to have reached cold screen with the stainless steel pull bar.
The adiabatic pull bar of cold screen spigot and socket type supports structurally not only to have the advantage that traditional pull bar supports but also has desirable insulation effect, and the adiabatic pull bar of cold screen spigot and socket type supports characteristics such as having convenient fixing simple in structure, therefore more welcome.
