Abstract
The utility model discloses a kind of liquid nitrogen container cock body, comprises cock body, it is characterized in that, described cock body entirety is in cylindric, and smooth surface is smooth, offers some guide grooves at cylindrical axial surface, cylindrical upper end center offers connecting bore, and cock body adopts thermal insulating material to make.The nitrogen of evaporation can effectively be discharged by liquid nitrogen container cock body described in the utility model, improves liquid nitrogen container safety in utilization, and improve the static Keeping life of product, improve the quality of products, cock body there will not be crackle, dust phenomenon, ensures that in container, sample is not contaminated.
Description
Technical field
The utility model relates to liquid nitrogen container, particularly relates to a kind of liquid nitrogen container cock body.
Background technology
Liquid nitrogen container take liquid nitrogen as refrigerant, preserves animal semen, organ, bacterial classification and other valuable biological sample, be widely used in the fields such as animal husbandry, medical treatment and scientific research.The accessory that must be equipped with in liquid nitrogen container is cock body, for slowing down the thermal exchange inside and outside container, avoiding liquid nitrogen excessive vaporization, effectively extending cold preservation time, the sample safety that protection stores.Traditional cock body coordinates with liquid nitrogen container, in use easily occurs cooling crack and dust releasing phenomenon, easily causes sample contamination in container.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of liquid nitrogen container cock body is provided, solve liquid nitrogen container cock body traditional in current technology and easily occur cooling crack and dust releasing phenomenon, easily cause the problem of sample contamination in container.
For solving above technical matters, the technical solution of the utility model is:
A kind of liquid nitrogen container cock body, comprises cock body, it is characterized in that, described cock body entirety is in cylindric, and smooth surface is smooth, offers some guide grooves at cylindrical axial surface, cylindrical upper end center offers connecting bore, and cock body adopts thermal insulating material to make.Liquid nitrogen container cock body described in the utility model adopts the cylindrical structural mated with the neck tube internal diameter of liquid nitrogen container, guide groove is offered at cylindrical axial surface, can play on the one hand and propose an axial location effect, the nitrogen of evaporation can also be discharged by guide groove simultaneously, reduce the internal pressure of liquid nitrogen container, avoid the accident of blasting, avoid occurring that cooling crack causes dust releasing contaminated sample.Cock body adopts thermal insulating material to make, and slows down the thermal exchange inside and outside container, avoids liquid nitrogen excessive vaporization, effectively extend cold preservation time, the sample safety that protection stores.
Further, described cock body bottom edge chamfering, plays directional tagging, facilitates cock body to be inserted in neck tube, avoids cock body bottom edge to occur impact failure due to handling frequently, improves service life.
Further, described cock body bottom edge rounding, guiding is level and smooth, not cracky.
Further, described cock body adopts polystyrene to make, and polystyrene material there will not be crackle after immersing in liquid nitrogen, and sample in container can not be polluted without dust releasing, the coefficient of heat transmission of polystyrene is low, and being conducive to product Keeping life increases, and improves the quality of products.
Further, described cock body adopts 50g/cm
3foamed polystyrene make, greatly reduce difficulty of processing, save the process-cycle, reduce cost of parts.。
Compared with prior art, the utility model advantage is:
The nitrogen of evaporation can effectively be discharged by liquid nitrogen container cock body described in the utility model, improves liquid nitrogen container safety in utilization, and improve the static Keeping life of product, improve the quality of products, cock body there will not be crackle, dust phenomenon, ensures that in container, sample is not contaminated;
The simple applicability of the utility model structure is strong, and cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Disclosed in the utility model embodiment, a kind of liquid nitrogen container cock body is while slowing down the thermal exchange inside and outside container, avoids occurring cooling crack and dust releasing phenomenon, avoids sample in container to be polluted, and improves the static Keeping life of product.
As depicted in figs. 1 and 2, a kind of liquid nitrogen container cock body, comprises cock body 1, described cock body 1 entirety is in cylindric, and smooth surface is smooth, guarantees to fit well with the neck tube inwall of liquid nitrogen container, improve the effect slowing down interchange of heat, avoid liquid nitrogen excessive vaporization, effectively extend cold preservation time.Some guide grooves 2 are offered for proposing an axial location and nitrogen release at cylindrical axial surface, cylindrical upper end center offers connecting bore 3 and is connected with lid, cock body 1 bottom edge chamfering, cock body 1 bottom edge rounding in the present embodiment, play good directional tagging, cock body can be facilitated be placed into smoothly in the neck tube of liquid nitrogen container, avoid the bottom margin of cock body 1 to affect because handling appearance is damaged frequently the effect slowing down interchange of heat.
Cock body 1 adopts thermal insulating material to make, and cock body 1 adopts the foamed polystyrene of 50g/cm3 to make in the present embodiment.Polystyrene material there will not be crackle after immersing in liquid nitrogen, and can not pollute sample in container without dust releasing, difficulty of processing, low, saves the process-cycle, reduces cost of parts.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
