Abstract

The utility model relates to a seal structure field of flange, concretely relates to flange joint connects convenient to quick dismantlement. A flange joint connects convenient to quick dismantlement which characterized in that: it mainly comprises a pair of metal clamp, the metal clamp is half circle ring, and the recess that the cross -section is the rectangle is seted up to its inboard, a pair of metal clamp is mutually supported and is blocked the edge of flange, the outside at metal clamp both ends all is equipped with the connecting plate, has seted up the bolt hole on the connecting plate, through connecting plate and connecting bolt fixed connection between a pair of metal clamp. This flange joint connects can be applied to operating modes such as well low temperature, middle and low voltage, vibrations, keeps good leakproofness for a long time, prevents effectively that the flange from leaking, being convenient for to dismantle fast.

Description

A kind of Flange joint joint being easy to fast quick-detach
Technical field
This utility model relates to the sealing construction applications of flange, is specifically related to a kind of Flange joint joint being easy to fast quick-detach.
Background technology
Flange sealing structure is widely used in petrochemical industry because of its easy-to-dismount advantage.Owing to the complexity of working environment causes Flange joint position easily to leak.After leakage occurs, traditional Flanged Connection System needs to turn on all of pretension bolt and could be replaced pad, and owing to the complexity of working environment causes pretension bolt to be all difficult to turn on.At this time occasions such as low temperature, mesolow, vibrations in some, it is desirable to a kind of Flange joint joint being easy to quickly remove and install.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of Flange joint joint being easy to fast quick-detach, this Flange joint joint can be applied to the operating modes such as middle low temperature, mesolow, vibrations, the sealing that long-term holding is good, effectively prevents flange leakage, is easy to fast quick-detach.
For achieving the above object, technical solution adopted in the utility model is:
A kind of Flange joint joint being easy to fast quick-detach, it is characterized in that: it is mainly made up of a pair metal clip, described metal clip is semi-circular shape, offers the groove that cross section is rectangle inside it, and the pair of metal clip cooperates and blocked at the edge of flange;The outside at described metal clip two ends is equipped with connecting plate, and connecting plate offers bolt hole, connects by connecting plate and connecting bolt are fixing between a pair metal clip.
Described flange includes that upper flange plate, lower flange and gasket seal, the upper surface of described upper flange plate are the inclined-plane of the most angled inclination, and the lower surface of described lower flange is also the inclined-plane of the most angled inclination.
Acquired by this utility model have the beneficial effect that 1, flange sealing structure of the present utility model can be applied to the operating modes such as middle low temperature, mesolow, vibrations, and can keep good sealing for a long time, effectively prevents the leakage of flange.2, this utility model provide being metal clip of pretightning force and unconventional pretension bolt, compared with traditional Flanged Connection System, the pretightning force that gasket seal in this utility model is subject to evenly, thus avoids the uneven leakage failure caused because of pretightning force.3, in this utility model, Flange joint joint is more beneficial for fast quick-detach compared with traditional Flanged Connection System.

In figure: 1 connecting plate, 2 metal clip, 3 upper flange plates, 4 gasket seals, 5 lower flanges, 6 connecting bolts.
Detailed description of the invention
In order to be more fully understood that this utility model, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further (as Figure 1-3).
A kind of Flange joint joint being easy to fast quick-detach, it is mainly made up of a pair metal clip 2, described metal clip 2 is semi-circular shape, groove that cross section is rectangle (i.e. metal clip 2 cross section for " [ " type) is offered inside it, the pair of metal clip 2 cooperates and is blocked at the edge of flange (described flange is made up of upper flange plate 3, lower flange 5 and gasket seal 4) (will complete the wrapping in edge of flange, compress upper flange plate 3 and lower flange 5);The outside at described metal clip 2 two ends is equipped with connecting plate 1, and connecting plate 1 offers bolt hole, by connecting plate 1 and the fixing connection of connecting bolt 6 between a pair metal clip 2.
Described flange includes upper flange plate 3, lower flange 5 and gasket seal 4, the inclined-plane that upper surface is the most angled inclination of described upper flange plate 3, and the lower surface of described lower flange 5 is also the inclined-plane of the most angled inclination.I.e. all do slope process outside the ring flange of upper flange plate 3 and lower flange 5.
After metal clip 2 clamping, contact of incline plane outside the inner side of metal clip 2 and upper flange plate 3, lower flange 5 also extrudes upper flange plate 3 and lower flange 5 and provides enough pretightning force for Flanged Connection System.
Only Application Example of the present utility model described above, the interest field that certainly can not limit this utility model with this, therefore change according to the equivalence that this utility model claim is made, still belong to protection domain of the present utility model.
