Abstract
The utility model discloses a multi-piece combination type large-diameter pipeline first-aid repair joint, comprising several sheets of housings and sealing gaskets, the housings are in a circumferential uniform distribution according to a certain angel, the radial two sides of each housing are respectively provided with a flange extending outwards, the flange is provided with screw holes, each screw hole is provided with a semicircular boss extending outwards with the screw hole as the circle center, the flange between the screw holes and the external side of the housing are provided with a triangular reinforced rib, and the housings are connected via bolts. The first-aid repair joint in the utility model is advantaged by multi-piece combination, simple casting, good guarantee of casting precision, small housing volume, good guarantee of wall thickness, saving of raw materials, small volume, light weight, as well as convenient transportation and installation.
Description
Technical field
The utility model relates to a kind of large diameter pipeline fast repairing of breaking that is used for, and relates to a kind of large diameter pipeline specifically and rushes to repair joint fast.
Background technique
Large diameter pipeline repairing joint is an equipment of rushing to repair usefulness at large diameter pipeline fast, is used for the quick repairing that large diameter pipeline breaks more, and this device is made up of multi-disc, and is simple in structure, easy for installation.The pipe first-aid joint that generally adopts at present is two involutory intermediate cryptographic packings of housing, uses bolt; For large diameter pipeline, two housings are big, wall thickness, and the casting difficulty is big, and heaviness, is installed all very inconveniently at transportation, because volume is big, casting accuracy is difficult to guarantee, the repairing weak effect.
The model utility content
The utility model provides a kind of casting simple, and casting accuracy guarantees that well the housing volume is little, and wall thickness guarantees that well volume is little, and is in light weight, easy transportation and installation be used for the large diameter pipeline repairing fast of breaking.
The utility model technical solution problem provides following scheme:
A kind of multiple combined-type large diameter pipeline repairing joint, comprise several pieces housings and sealing gasket, it is characterized in that: described several pieces housings are more than three or three, several pieces housings are enclosed a circle, and a circumference is enclosed at its two ends respectively, the left and right sides of several pieces housings is respectively equipped with flange, passes through bolt between the flange of adjacent housings.
Described multiple combined-type large diameter pipeline repairing joint, it is characterized in that: the flange of the and arranged on left and right sides of described housing stretches out respectively, on the described flange screw is arranged, it is the outside semicircular boss in the center of circle that described screw is provided with the screw, flange between described screw and screw and hull outside have the triangle stiffening rib, connect by bolt between the flange of described adjacent housings.
Described multiple combined-type large diameter pipeline repairing joint, it is characterized in that: described flange inboard has straight trough vertically, the cross section of described straight trough is a right-angled trapezium, big the inside, outside is little, and described housing two circumferential end madial walls are provided with annular groove, and described annular groove communicates to straight trough with two flange shaft, described annular groove is an isosceles trapezoid, little in big outward, in the annular groove of described housing sealing gasket is housed, described sealing gasket axial cross section is trapezoidal.
Described multiple combined-type large diameter pipeline repairing joint, it is characterized in that: described is that the outside semicircular boss in the center of circle is thicker than flange with the screw.
Described multiple combined-type large diameter pipeline repairing joint, it is characterized in that: described sealing gasket is a rubber gasket.
The utility model adopts the mode of multi-disc combination, and casting is simple, and casting accuracy guarantees that well the housing volume is little, and wall thickness guarantees well, saves raw material, and volume is little, and is in light weight, and transportation is installed and all made things convenient for.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of large diameter pipeline repairing joint is made up of 4 housings 1 and sealing gasket 2, and 4 housings 1 are enclosed a circle, connect as one by the bolton flange between the housing.The radially both sides of housing 1 have outward extending flange 3 respectively, screw 4 is arranged on the flange 3, it is the outside semicircular boss 5 in the center of circle that the place of screw 4 has with screw 4, there is triangle stiffening rib 6 in the flange 3 that screw 4 and screw are 4 and housing 1 outside, two side flanges 3 have straight trough 7 vertically in screw 4 inboards, straight trough 7 is a right-angled trapezium, big the inside, outside is little, 1 liang of circumferential end of housing is circumferential annular groove 8, communicate to straight trough 7 with two flange shaft, annular groove 8 is an isosceles trapezoid, and is little in outer big, in the annular groove 8 of housing 1 sealing gasket 2 is housed, sealing gasket 2 axial cross sections are trapezoidal.
