Description
Technical field
The utility model relates to a kind of fluid-transporting tubing component, and more particularly, it relates to a kind of fixing-assembly being exclusively used in vacuum and low temperature pipe insulation cylinder.
Background technique
In low-temperature deep liquefaction, cryogen storing field, sky divides and low temperature industry adopts vacuum tube form in Liquid transfer, ensure that the liquid gasification rate in transmitting procedure, product yield is guaranteed.
Wherein by the restriction of installation conditions, according to use, maintenance requirement, conveniently pipeline is transported to job site, vacuum pipe adopts segmented making to transport to scene and assembles, usually thermal insulating material can be wound around in the joint of two vacuum pipes, form a heat-preservation cylinder, run off from the joint of two vacuum pipes to avoid the cold in interior pipe; Then can be wound around one deck aluminium flake in the periphery of heat-preservation cylinder and fix, finally fixing two ring end plates at heat-preservation cylinder along the two ends of the axial direction of vacuum pipe, and by being welded and fixed, thermal insulating material can be completely wrapped; But ring end plate is very not convenient by the mode be welded and fixed, complex operation, working efficiency is low, and secondly, the mode be welded and fixed is irreversible, causes follow-uply to carry out dismounting and change to thermal insulating material, is unfavorable for the permanent use of vacuum pipe.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can make the fixing of ring end plate and dismounting more convenient, simple to operate, effectively can promote the fixing-assembly being exclusively used in vacuum and low temperature pipe insulation cylinder of working efficiency.
For achieving the above object, the utility model provides following technological scheme: a kind of fixing-assembly being exclusively used in vacuum and low temperature pipe insulation cylinder, comprise two pieces of ring end plates and be positioned at the aluminium flake outside heat-preservation cylinder, two ends that described aluminium flake is positioned at heat-preservation cylinder are all outward extended with annular protrusion along heat-preservation cylinder radial direction; Two pieces of described ring end plates are all extended with clamping ring towards heat-preservation cylinder direction; The annular groove matched with annular protrusion is all offered in described clamping ring.
By adopting technique scheme, when two pieces of ring end plates need two ends being fixed on heat-preservation cylinder, by cooperatively interacting between the annular protrusion on aluminium flake and the annular groove on clamping ring, ring end plate is made to be fastened on two ends of heat-preservation cylinder, and the mode be fastened is relative to the means of fixation adopting welding in prior art, can make the fixing of ring end plate and dismounting more convenient, and simple to operate, effectively can promote working efficiency.
The utility model is set to further: also offer annular groove in described clamping ring; The two ends of described aluminium flake are provided with the positioning ring matched with annular groove.
By adopting technique scheme, annular groove and positioning ring cooperatively interact and locate, and ring end plate can be made to obtain effective location, avoid its axial direction along heat-preservation cylinder to offset, the fixed effect of ring end plate is promoted further.
The utility model is set to further: the cross section of described annular groove and positioning ring is all rectangular; Described clamping ring away from the end cross-sectional of ring end plate all in barb-like.
By adopting technique scheme, all rectangular fixed effect can strengthening clamping ring and ring end plate of cross section of annular groove and positioning ring; Clamping ring is barb-like away from the end cross-sectional of ring end plate, and it is more convenient to work as when clamping ring is inserted in peripheral to heat-preservation cylinder, makes the installation of ring end plate more convenient.
The utility model is set to further: the corresponding annular groove place place of described clamping ring all to stretch out formation protruding ring along heat-preservation cylinder radial direction.
By adopting technique scheme, can make to have a Point of Strength when stripping ring end plate, it is more convenient to make when stripping ring end plate, can strengthen practicability of the present utility model further.

Fig. 2 is the A portion partial enlarged drawing that the utility model is exclusively used in the fixing-assembly embodiment of vacuum and low temperature pipe insulation cylinder.
Reference character: 1, ring end plate; 2, aluminium flake; 3, annular protrusion; 4, clamping ring; 5, annular groove; 6, annular groove; 7, positioning ring; 8, protruding ring.
Embodiment
Referring to figs. 1 through Fig. 2, the fixing-assembly embodiment that the utility model is exclusively used in vacuum and low temperature pipe insulation cylinder is described further.
As shown in Figure 1 to Figure 2, a kind of fixing-assembly being exclusively used in vacuum and low temperature pipe insulation cylinder, the aluminium flake 2 comprising two pieces of ring end plates 1 and be positioned at outside heat-preservation cylinder, two ends that aluminium flake 2 is positioned at heat-preservation cylinder are all outward extended with annular protrusion 3 along heat-preservation cylinder radial direction; Two pieces of ring end plates 1 are all extended with clamping ring 4 towards heat-preservation cylinder direction; The annular groove 5 matched with annular protrusion 3 is all offered in clamping ring 4.
By adopting technique scheme, when two pieces of ring end plates 1 need two ends being fixed on heat-preservation cylinder, by cooperatively interacting between the annular protrusion 3 on aluminium flake 2 and the annular groove 5 on clamping ring 4, ring end plate 1 is made to be fastened on two ends of heat-preservation cylinder, and the mode be fastened is relative to the means of fixation adopting welding in prior art, can make the fixing of ring end plate 1 and dismounting more convenient, and simple to operate, effectively can promote working efficiency.
Further, annular groove 6 is also offered in clamping ring 4; The two ends of aluminium flake 2 are provided with the positioning ring 7 matched with annular groove 6, annular groove 6 and positioning ring 7 cooperatively interact and locate, ring end plate 1 can be made to obtain effective location, avoid its axial direction along heat-preservation cylinder to offset, the fixed effect of ring end plate 1 is promoted further; Further annular groove 6 is all rectangular with the cross section of positioning ring 7; Clamping ring 4 away from the end cross-sectional of ring end plate 1 all in barb-like, all rectangular fixed effect can strengthening clamping ring 4 and ring end plate 1 of cross section of annular groove 6 and positioning ring 7; Clamping ring 4 is barb-like away from the end cross-sectional of ring end plate 1, and it is more convenient to work as when clamping ring 4 is inserted in peripheral to heat-preservation cylinder, makes the installation of ring end plate 1 more convenient.
In above-mentioned embodiment, clamping ring 4 corresponding annular groove 5 place place all stretches out along heat-preservation cylinder radial direction and forms protruding ring 8, can make, when stripping ring end plate 1, there is a Point of Strength, it is more convenient to make when stripping ring end plate 1, can strengthen practicability of the present utility model further; Wherein, aluminium flake 2 adopts the aluminium leather of 0.4 to do, and aluminium flake 2 scene is adopted and is screwed; Wherein closely cooperate between ring end plate 1 and aluminium flake 2, inner practical sealer connects sealing, needs moistureproof and is not mechanically damaged and the washing away of sleet; Before fastening ring end plate 1, need on ring end plate 1, offer through hole and be inserted in on vacuum pipe.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
