Description
Technical field
The utility model relates to a kind of low-temperature (low temperature) vessel, particularly a kind of small-sized low-temperature (low temperature) vessel top braces device.
Background technique
In recent years, along with rapid economy development, the national economy every profession and trade is also increasing for the demand of gas, all kinds of low tempertaure storage equipment also arise, big to the cryogenic vacuum storage tank, little of cryogenic insulated cylinder, the small-sized low-temperature (low temperature) vessel that also has the similar vertical insulated gas cylinder of a class in the middle of it, multiple call is arranged on its market at present, and crying of having is easily cold soon, have cry the variation jar etc., this type of low-temperature (low temperature) vessel is because its structure is less, time of storage is longer, and relative evaporation is little and be convenient to move, and firmly gets liking of numerous clients.Ensure that main structure that this kind equipment possesses above characteristics then is that its inside top is hung and drawn supporting structure, this class formation is the safety and the quality assurance of entire container, reliability and intensity that pull-up structure is hung at its top are most important, it not only will ensure the requirement of strength of hanging pull-up structure, but also the leakage of any trace must not be arranged, otherwise jeopardize the safety of entire container, and even the relevant personnel's life safety.Using more top braces to hang pull-up structure on the market is monolateral fillet weld welding, though major accident does not take place in this class formation in the middle of the practice process, but reach in the long run from security standpoint, this class formation is science not, be mainly monolateral fillet weld and not only born the weight that supports the whole contents device, also to play the effect of sealing, simultaneously, this type of fillet weld is just carried out the non-destructive inspection on surface mostly, can not detect the defective of interior surface certain depth, in case the fillet weld subsurface defect is expanded in the middle of the practice process, will jeopardize entire container safety, even personnel's life safety.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides the small-sized low-temperature (low temperature) vessel top braces device of a kind of safety coefficient height, good sealing effect.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of small-sized low-temperature (low temperature) vessel top braces device, comprise neck tube flange 3, neck tube 2 and outer distributing head 1, described neck tube flange 3 end faces are penetrated with through hole, described outer distributing head 1 end face is provided with tapped hole, described neck tube 2 one ends are fixed by welding in described neck tube flange 3 through holes, and described neck tube 2 the other ends are provided with outside thread and cooperation is installed in the tapped hole of described outer distributing head 1, are tightly connected between described neck tube 2 and the described outer distributing head 1.
Further, be tightly connected by fillet welding between described outer distributing head 1 end face and described neck tube 2 sidewalls.
Further, be connected and fixed by fillet welding between described neck tube flange 3 end faces and described neck tube 2 sidewalls.
Further, be connected and fixed by fillet welding between described neck tube 2 end faces and described neck tube flange 3 through-hole walls.
Further, described neck tube flange 3 sidewalls are provided with air hole 31.
Further, described outer distributing head 1 top is provided with bolt hole 11 and is used to install the annular groove 12 of seal ring.
(3) beneficial effect
The small-sized low-temperature (low temperature) vessel top braces of the utility model device has following having a few:
1, simple in structure, this type of top braces device is mainly formed by three, and material is taken from more or less freely;
2, safe, screw thread+welded structure is adopted in being connected between neck tube and the outer distributing head, directly replaces the strength support function of upper corners weld seam, and welding just seals, and can improve device security greatly; Then adopt two pass fillet weld structure with being connected between the neck tube flange, can reduce the following sightless subsurface defect in surface that welding is produced, the Security that improves equipment equally;
3, adjustability is strong, because equipment is in the middle of actual manufacture process, the manufacturing tolerances that more or less has a bit, if it is big that last lower seal head space becomes, conventional neck tube can only be that inner container is promoted, thereby the support of pipe arrangement and bottom is impacted, and this structure is owing to there is a certain amount of reach, can regulate earlier, finally weld again.
Description of drawings
Fig. 1 is the structural representation of the small-sized low-temperature (low temperature) vessel top braces of the utility model device.
Embodiment
Consult Fig. 1, the utility model provides a kind of small-sized low-temperature (low temperature) vessel top braces device, comprise neck tube flange 3, neck tube 2 and outer distributing head 1, neck tube flange 3 end faces are penetrated with through hole, outer distributing head 1 end face is provided with tapped hole, neck tube 2 one ends are fixed by welding in neck tube flange 3 through holes, and neck tube 2 the other ends are provided with outside thread and cooperation is installed in the tapped hole of outer distributing head 1, are tightly connected between neck tube 2 and the outer distributing head 1; In the present embodiment, realize being tightly connected by fillet welding between outer distributing head 1 end face and neck tube 2 sidewalls; Be connected and fixed by fillet welding between neck tube flange 3 end faces and neck tube 2 sidewalls; Simultaneously, be connected and fixed by fillet welding between neck tube 2 end faces and neck tube flange 3 through-hole walls; Defectives such as bubble that when welding in order to reduce fillet weld is produced and crackle are provided with air hole 31 at neck tube flange 3 sidewalls, and this air hole is through to its inwall from neck tube flange 3 outer walls; Install in order to increase sealing and to be convenient to, distributing head 1 top is provided with bolt hole 11 and the annular groove 12 that is used to install seal ring outside.The utlity model has following characteristics:
1, the neck tube flange is an III level forging, and itself and inner container adopt two-sided through welding structure, can guarantee the reinforcement requirement of inner container, can satisfy the Security of equipment;
2, outer distributing head is similarly III level forging, and itself and shell end socket weld, and adopts the one side welding with back formation welding technique, can guarantee the sealing of equipment interlayer;
3, then for inner container is suspended on the important in closing element of enclosure, this element not only need satisfy the requirement of working pressure to neck tube, also bear simultaneously inner container and the unsettled function of medium-weight, and the moment of flexure effect that produces when bearing inner container and wrapping up;
