Description
Technical field
The utility model is a kind of full-enclosed flange covering leaks clamping.Relate to the pipe-line system technical field.
Background technique
Though domestic patent or the patent application that multinomial flange covering leaks clamping is arranged now, as: " flange segmental arc pressure sealing jig " (publication number: CN2887532), " the sealing jig that is used for the flange connection " (notification number: 2519879), " pressure sealing jig " (publication number: CN2535648), " flange pressure sealing jig " (publication number: CN2111426), " novel flange formula band is pressed first-aid clamp " (patent No.: 200820107071), but they all are the leakage leak stopping that is used for the flange part, can only select different covering leaks clamping and mode according to the different leak condition of flange, produce the need that the different jig of various models satisfies leak stopping, and the main leak stopping that still damages at flange seal spare is only tightly wrapped flange leakage point.
The model utility content
The purpose of this utility model is a kind of leakage-blocking emergency that can solve various situation flange leakages of design, particularly can also be used for the flange body defectiveness and leak the safe and reliable full-enclosed flange of leak stopping covering leaks clamping.
Structure of the present utility model as depicted in figs. 1 and 2, for splitting two halves formula structure, it comprises hole for injecting glue (1), flange half-arc groove (2), pipe semi-circle (3), connecting bolt hole (4), injecting glue cock (5), sealing bolt (6) and section sealing surface (7).Half of splitting two halves formula jig is semicircle ring-type, the inboard cambered surface middle part of semicircular rings has flange half-arc groove (2), both sides that pipe semi-circle (3) is arranged, flange half-arc groove (2) has a plurality of outer hole for injecting glue (1) of leading to, and hole for injecting glue (1) is furnished with injecting glue cock (5) and sealing bolt (6); The two ends of semicircular rings respectively are fixed with ear, and a plurality of connecting bolts hole (4) is respectively arranged on the ear.
Described flange half-arc groove (2) is for connecting the groove of semicircular rings, and its cross section is a rectangle; Two halves relatively after, flange half-arc groove (2) is to circular;
Described pipe semi-circle (3) is for connecting the groove of semicircular rings, two halves relatively after, to circular;
The ear at described semicircular rings two ends is a rectangular block, and when two semicircular rings were relative, two ears were parallel relatively, connecting bolt hole (4) is relative, and maintains distance between the two relative ears, so that two semicircular rings are when connecting, seal face (7) is compressed, and pipe semi-circle (3) compresses with pipeline;
The section sealing surface (7) of jig is straight, smooth, and pipe semi-circle (3) requires to pass through mutually, smooth.
By connecting bolt hole (4) two halves of jig are connected combination with connecting bolt, flange half-arc groove (2) just can be wrapped entirely leaking flange, pipe semi-circle (3) is closely wrapped the pipeline section that is connected with flange, be fastenedly connected bolt and make that the sealing surface (7) of jig is tight, install injecting glue cock (5) in hole for injecting glue (1) outside, inject sealing compound by injecting glue cock (5), the seal gease inspection is filled with not after leakage in each position, and sealing bolt (6) is installed in dismounting injecting glue cock (5) down.
Full-enclosed flange covering leaks clamping can be applicable to that a variety of causes causes the emergency leakage blocking of flange leakage, can also be used for the leak stopping that the flange body defectiveness leaks especially.It all tightly wraps in the jig damaging the leakage flange, and safety, reliable.
This jig is practical full-enclosed flange covering leaks clamping, is applicable to the not stopping transportation leak stopping repairing of output oil, product oil, rock gas, waterpipe flange leakage.

Embodiment
Embodiment. this example is the experiment jig at Φ 108mm gas pipeline, and it constitutes as depicted in figs. 1 and 2.Half of splitting two halves formula jig is semicircle ring-type, the inboard cambered surface middle part of semicircular rings has flange half-arc groove (2), both sides that pipe semi-circle (3) is arranged, flange half-arc groove (2) has a plurality of outer hole for injecting glue (1) of leading to, and hole for injecting glue (1) is furnished with injecting glue cock (5) and sealing bolt (6); The two ends of semicircular rings respectively are fixed with ear, and a plurality of connecting bolts hole (4) is respectively arranged on the ear.
Wherein:
Flange half-arc groove (2) is for connecting the groove of semicircular rings, and its cross section is a rectangle; Two halves relatively after, flange half-arc groove (2) is to becoming cylindrical cavity;
Pipe semi-circle (3) is for connecting the groove of semicircular rings, two halves relatively after, to circular;
The semicircular rings jig is of a size of: internal diameter 108mm (diameter of pipe semi-circle (3)), external diameter 350mm, ring width 380mm, flange half-arc groove (2) diameter 280mm, groove width 180mm;
The ear at semicircular rings two ends is 380 * 75 * 35mm rectangular block, when two semicircular rings are relative, two ears are parallel relatively, connecting bolt hole (4) is relative, and maintain the distance of 20mm between the two relative ears, so that when two semicircular rings connect, seal face (7) is compressed, pipe semi-circle (3) compresses with pipeline;
