Abstract

The utility model relates to a sealed half-ring inner hoop pipe type connecting apparatus which can brake, comprising upper and lower sealing covers, sealing rings which are inserted in the both ends of the sealing cover and the periphery wall of a pipeline, an inner hoop half ring which is arranged in the sealing cover for tightening the periphery wall of a connection pipe and can be connected in disassembly, and a pin which is cooperated with the half ring and is positioned. The sealed half-ring inner hoop pipe type connecting apparatus is characterized in that the pin is fixedly arranged on a connecting pipeline, while an inner ring groove which is matched with the pin is formed on the inner wall of the inner hoop half ring which can be directly connected to the sealing cover. The utility model has the advantages that the manufacture of a pin hole does not need to be matched a drill; the positioning mode of the pin and the inner ring groove is reliable, convenient, and rapid; meanwhile, material is saved, and technology is simplified.

Description

Sealed half-ring inner hoop pipe type connecting apparatus

The utility model relates to a kind of assembling pipe joint, relates in particular to the quick connecting pipe device of hoop pipe type in a kind of semi-ring.

Thereby the claimant has proposed a kind of assembling pipe joint of realizing that reliable sealing can't blue dish of braking in its application number is 94239303.1 utility model patent, wherein two connected tubes are formed by connecting by half positioning ring or the coupling ring of lock ring on its periphery wall integratedly, and its orientation type is connected tube and half positioning ring or coupling ring to be joined draw-bore set positioning dowel again.Though the assembling pipe joint of this structure can be prevented the axial play of connecting tube safely and circumferentially rotate to keep reliable sealing, but because its axially locating mode still need be joined draw-bore after fastening piece (half positioning ring or coupling ring) and connected tube spiral shell are tied, this is to piping erection, and particularly the construction of large-scale pipeline is still inconvenient.

The purpose of this utility model provides and does not a kind ofly need to join draw-bore and just can directly make pin order axially locating thereby but hoop pipe type connection set in the semi-ring of braking sealing is installed rapidly easily.

For achieving the above object, assembling pipe joint of the present utility model comprises: be set in the connected pipe perisporium outer on, lower sealing cover, be embedded last, on the lower sealing cover two ends and the seal ring between the pipeline periphery wall, be located at the interior hoop semi-ring that removably connect of lock ring on the connected tube periphery wall in the described sealing cover, with with described in the hoop semi-ring cooperates the pin of locating to order, be characterized in, described pin is to be fixedly installed on the perisporium at nearly two end part of two connected pipes, is formed with the inner groove with described pin relative engagement in described on the inwall of hoop semi-ring.

Above-mentioned interior hoop semi-ring comprises two, and they are connected removably relatively by fixed connecting piece.

Above-mentioned interior hoop semi-ring is one, and it is removably fixedlyed connected with one of described sealing cover.

Below by specific embodiment and specify the purpose of this utility model and characteristics in conjunction with the accompanying drawings.

But Fig. 1 is the interior longitudinal section that binds round an embodiment of pipe type connection set of the semi-ring of braking sealing of the present utility model;

Fig. 2 is the sectional elevation of getting along " A-A " line among Fig. 1, has wherein omitted the partial fixing link;

Fig. 3 is the longitudinal section of interior hoop semi-ring embodiment illustrated in fig. 1;

Fig. 4 is the sectional elevation of getting along " C-C " line among Fig. 3;

Fig. 5 is half plan view of Fig. 3;

But Fig. 6 is the interior vertical half sectional view that binds round another embodiment of pipe type connection set of the semi-ring of braking sealing of the present utility model;

Fig. 7 is an interior plan view that binds round semi-ring embodiment illustrated in fig. 5;

Fig. 8 is the horizontal half sectional view along " B-B " position among Fig. 6.

But Fig. 1 to 5 is depicted as first embodiment who binds round the pipe type connection set in the semi-ring of braking sealing of the present utility model, as shown in the figure, it comprises: be set in the outer upper and lower sealing cover 1 of two connected pipes, 6 perisporiums, 2, the relative attachment post 8 of vertical ground projection two on the inwall of lower sealing cover 2 outside it leaves pipeline wherein, each upper end is respectively equipped with screw 15 at it; Be embedded the combined seal ring 5 between described sealing cover two ends and connected tube outer wall; Be fixedly installed on the pin 4 on the perisporium of opposite end of pipeline 6 respectively; The one interior hoop semi-ring 3 that equates with pipeline 6 outer radius, its inwall middle body is provided with annular projection portion 10, the end of two connecting tubes is by on the bi-side that are located at described lug boss 10, on its inwall, be formed with inner groove 9 with described pin 4 pairings near two ends, opposite side at semi-ring 3 outer walls is extended with two lugs 13 along the horizontal diameter direction, be provided with the through hole 12 that matches mutually with described attachment post screw 15 on each lug 13, hoop semi-ring 3 was connected one with lower sealing cover 2 in screw 7 made by described through hole 12 and screw 15.

But Fig. 6 to 8 is depicted as second embodiment who binds round the pipe type connection set in the semi-ring of braking sealing of the present utility model.As shown in the figure, different with the foregoing description with lower sealing cover except hoop semi-ring in it, remaining part is all identical, and all same sections are all represented with identical label among the figure.In the present embodiment, the interior hoop semi-rings 3 that use two removably connects relatively ', the end walls opposite side of each which is provided with through hole 16 facing each other along a pair of connection lug 11 of the axial projection in its mating face at it, fuses by bolt 14 and nut (not shown).

Can be clear that the advantage that adopts hoop duct type jockey in the semi-ring of the present utility model from above-described embodiment:

Because pin-and-hole is directly radially to get out on connected pipe, and shop bolt directly is provided in the pin-and-hole of connected pipe, therefore, compared with the prior art, do not need tube connector and semi-ring are joined draw-bore and equipped shop bolt integratedly, therefore process very convenient, thereby can save time and cut down finished cost; Owing to be formed with room annular groove with the pin scarf at the inwall of interior hoop semi-ring, thereby can make connecting pipe carry out axial location at any circumferential position of its relative semi-ring, it is not only reliable that therefore the location be installed, and very convenient rapidly; Simultaneously the location structure that cooperates with pin of this annular groove also can be used instead and only depend in one hoop semi-ring spiral shell to forge seal cover to be fixedly connected with the way of pipeline, therefore can further save material and simplification technology.
