Abstract
The utility model discloses a kind of vacuum heat-insulating pipe, comprise male pipe and female pipe, described mother's pipe and male pipe all arrange inner and outer tubes, and described mother's pipe is connected by flange plate with male pipe, it is characterized in that: described link position is provided with black box; Described black box comprises the first seal ring be connected with male pipe and the second seal ring be connected with female pipe, and first, second seal ring described is conflicted connection mutually; Described first seal ring and the second seal ring opposing side are provided with elastic outstanding circle, and described second seal ring and the first seal ring opposing side are provided with the elastic groove circle corresponding with outstanding circle; This vacuum heat-insulating pipe is convenient to be installed, and can ensure its sealability.
Description
Technical field
The utility model relates to a kind of vacuum heat-insulating pipe.
Background technique
This patent is mainly used in the connection between the vacuum heat-insulated pipe pipeline section of conveying cryogenic liquid (temperature is generally lower than-100 DEG C), by the pipe-line system by cryogenic insulating pipeline section connection composition transmission deep cooling medium.Owing to carrying the particularity of deep cooling medium, propose very high requirement for conveying pipeline section coupling piece: the sealability should guaranteeing connecting joint place, namely fed sheet of a media can not leak through coupling piece; Also to maintain good heat-insulating property.Consider the applied environment of delivery pipeline system in addition, relate to installation, safeguard and because of many situations such as dismountings in particular cases, therefore the design synthesis of vacuum heat-insulated pipe coupling piece is thought of as: good sealability, good heat-insulating property, it is convenient to install, convenient disassembly.
At present, vacuum tube when mounted, the link position of flange plate is arranged by the seal ring of leakproof, but between two seal rings that flange plate is connected, be provided with an independent seal ring, improving sealing, this seal ring, is arrange separately, easily make it fall down when installation, thus inconvenient its is installed.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of convenient installation, and can ensure a kind of vacuum heat-insulating pipe of its sealability.
For achieving the above object, the utility model provides following technological scheme: a kind of vacuum heat-insulating pipe, and comprise male pipe and female pipe, described mother's pipe and male pipe all arrange inner and outer tubes, described mother's pipe is connected by flange plate with male pipe, and described link position is provided with black box; Described black box comprises the first seal ring be connected with male pipe and the second seal ring be connected with female pipe, and first, second seal ring described is conflicted connection mutually; Described first seal ring and the second seal ring opposing side are provided with elastic outstanding circle, and described second seal ring and the first seal ring opposing side are provided with the elastic groove circle corresponding with outstanding circle.
The utility model is set to further: described outstanding circle and the first seal ring are angularly arranged, and is provided with bracing ring between outstanding circle and the first seal ring.
The utility model is set to further: the elastic ring being provided with angled setting in described groove circle, described elastic ring with outstanding enclose to conflict be connected.
The utility model is set to further: described outstanding circle external diameter is greater than elastic ring external diameter, and outstanding circle internal diameter is less than elastic ring external diameter.
Technique effect: by arranging inconsistent projection circle and groove circle on the first seal ring, the sealing of first, second seal ring is made to become better, and projection circle and groove circle are arranged to have flexible, better tightness can be made, the elastic ring of angled setting and projection circle can make whole sealing ring tightness can be better, the setting of bracing ring can prevent its sealing effect to be deteriorated, this set not only increases sealing effect, and do not need seal ring to be installed separately to increase the sealability of whole seal ring, make its installation become convenient.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of vacuum heat-insulating pipe embodiment of the utility model;
Fig. 2 is A place enlarged view in Fig. 1.
Reference character: 1, female pipe; 11, the first seal ring; 111, outstanding circle; 112, bracing ring; 2, public pipe; 21, the second seal ring; 211, groove circle; 212, elastic ring.
Embodiment
Referring to figs. 1 through Fig. 2, a kind of vacuum heat-insulating pipe embodiment of the utility model is described further.
As shown in Figure 1 to Figure 2, a kind of vacuum heat-insulating pipe, comprises male pipe 2 and female pipe 1, and described female pipe 1 and male pipe 2 all arrange inner and outer tubes, and described female pipe 1 is connected by flange plate with male pipe 2, and described link position is provided with black box; Described black box comprises the first seal ring 11 be connected with male pipe 2 and the second seal ring 21 be connected with female pipe 1, and first, second seal ring 21 described is conflicted connection mutually; Described first seal ring 11 and the second seal ring 21 opposing side are provided with elastic outstanding circle 111, and described second seal ring 21 is provided with the elastic groove circle 211 corresponding with outstanding circle 111 with the first seal ring 11 opposing side; Described outstanding circle 111 and the first seal ring 11 are angularly arranged, and outstanding are provided with bracing ring 112 between circle 111 and the first seal ring 11; Be provided with the elastic ring 212 of angled setting in described groove circle 211, described elastic ring 212 is conflicted with outstanding circle 111 and is connected; Described outstanding circle 111 external diameter is greater than elastic ring 212 external diameter, and outstanding circle 111 internal diameter is less than elastic ring 212 external diameter.
By arranging inconsistent projection circle and groove circle 211 on the first seal ring 11, make first, the sealing of the second seal ring 21 becomes better, and projection circle and groove circle 211 are arranged to have flexible, better tightness can be made, the elastic ring 212 of angled setting and projection circle can make whole sealing ring tightness can be better, the setting of bracing ring 112 can prevent its sealing effect to be deteriorated, this set not only increases sealing effect, and do not need seal ring to be installed separately to increase the sealability of whole seal ring, its installation is made to become convenient.
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.
