Abstract
The utility model discloses a double-socket flexible casing. The double-socket flexible casing comprises an upper socket and a lower socket, wherein the upper and lower sockets are prepared by cutting a surface passing through the central axis of a casing body, the two ends of the upper and lower sockets are respectively provided with a split flange, the two ends of the upper and lower sockets are internally provided with multiple seal rings, and the outer sides of the two ends of the upper and lower sockets are provided with split flanges for tightly pressing the seal rings. According to the utility model, the ends of the two sockets of the casing and a connected pipeline are sealed by use of the seal rings, flexible connections are formed between the two sockets and the connected pipeline by virtue of the split flanges, and the casing and the connected pipeline are not required to be welded. The double-socket flexible casing disclosed by the utility model is most suitable for the urgent repair and transformation of cast-iron pipelines.
Description
Technical field
The utility model relates to the device of a kind of pipe pressurized repairing or transformation, particularly a kind of two flexible sleeves that hold.
Background technique
Have a kind of assembling pipe joint at present, comprise a sleeve pipe, the sleeve pipe two ends connect two segment pipes through flange, and this kind assembling pipe joint is after factory process is good, are used for site operation and connect two segment pipes.Can only be used for the connection of two segment pipes not with pressure.Can not realize the repairing of band pressure or the transformation of pipeline.
Summary of the invention
The problem that the utility model will solve is: a kind of two flexible sleeves that hold that can rush to repair or transform pipeline with pressure are provided.
For addressing the above problem:
The two flexible sleeves that hold of the utility model comprise the last bellmouth and following bellmouth that is cut into from the face through the body central axis; The two ends of last bellmouth and following bellmouth are equipped with split flange; Be provided with the seal ring mounting groove in the two ends of last bellmouth and following bellmouth; Many circles seal ring along last bellmouth axially-aligned is installed in each seal ring mounting groove, and the outside at the last bellmouth and the two ends of following bellmouth is equipped with the differential of splitting that is connected with the split flange at the last bellmouth and the two ends of following bellmouth, splits differential and compresses seal ring.
In order to realize that the band pressure drag of pipeline is broken, is convenient to pipeline is transformed, described upward bellmouth or following bellmouth are provided with pipe pressurized blocking-up interface.
The beneficial effect of the utility model: seal through seal ring between the end of two bellmouths of the utility model sleeve pipe and the connected pipeline; Two bellmouths flexibly connect through splitting to form between differential and the connected pipeline; Sleeve pipe and connected pipeline do not need welding, are fit to repairing, safeguard or transform the cast iron tube with pressure that is difficult for welding.

Embodiment
As shown in Figure 1 a kind of pair is held flexible sleeve, comprises bellmouth 5 and following bellmouth 6, and last bellmouth 5 is to be cut into from the face through its central axis by body with following bellmouth 6.The two ends of last bellmouth 5 and following bellmouth 6 are equipped with split flange 2, and as shown in Figure 3, split flange 2 is meant half flange that annular flange radially separates.The internal diameter of the two end portions of last bellmouth 5 and following bellmouth 6 is bigger than the internal diameter of intermediate portion; Thereby in last bellmouth 5 and following bellmouth 6 two ends, form the seal ring mounting groove; Many circles seal ring 4 along last bellmouth 5 axially-aligned is installed in each seal ring mounting groove; The outside at the last bellmouth 5 and the two ends of following bellmouth 6 be equipped be connected with the split flange 2 at the last bellmouth 5 and the two ends of following bellmouth 6 split differential 1, split flange 2 with split differential 1 and be connected through bolt 3.As shown in Figure 4, split half flange that differential 1 is meant that also annular flange radially separates.The inner side surface of splitting differential 1 has boss, and the boss of splitting differential 1 compresses seal ring 4.Through regulating bolt 3, can regulate is split the impacting force of 1 pair of seal ring 4 of differential.As shown in Figure 2, last bellmouth 5 can be provided with pipe pressurized blocking-up interface 8 with following bellmouth 6.
Press the two as stated methods of holding flexible sleeve of in-service pipeline field fabrication at band, it is characterized in that: comprise the steps:
The last bellmouth 5 that (1) will two hold flexible sleeve and following bellmouth 6 are wrapped in outside the pending part of pipeline with pressure 7 (pipeline section that the pipeline section that need the pipeline section of repairing as leakages takes place, needs to safeguard perhaps need transformation); To go up bellmouth 5 and be welded into a body with following bellmouth 6; Form two axial weld seams 9 as shown in Figure 3; Seal ring mounting groove inside weld position is then lined during welding, and welding is taken off lining after accomplishing; After guaranteeing that welding is accomplished, seal ring mounting groove smooth surface contacts so that seal ring better seals with the seal ring mounting groove; The minimum diameter of last bellmouth 5 and following bellmouth 6 has certain interval greater than the external diameter of pipeline 7 between body that feasible upward bellmouth 5 and following bellmouth 6 are welded into and the pipeline 7.
(2) seal ring 4 is installed; Get a plurality of Stamping Steel Ribbons 10; Like Fig. 5 and shown in Figure 6; The length direction angle of the end face of Stamping Steel Ribbon 10 and Stamping Steel Ribbon 10 is an acute angle, with after Stamping Steel Ribbon 10 is on the pipeline 7 again with the bonding formation in two ends such as Fig. 7 and seal ring 4 shown in Figure 8, form the bonding interface 11 that has certain angle with the axis of seal ring 4 on the seal ring 4.Seal ring 4 is pushed into the seal ring mounting groove, three seal rings 4 of packing into as stated above in each seal ring mounting groove; The bonding interface 11 of each seal ring mounting groove inner seal ring 4 staggers mutually.
(3) differential 1 is split in installation; Be connected at the split flange 2 external application bolts 3 of last bellmouth 5 and following bellmouth 6 and split differential 1; And make and split differential 1 and compress seal ring 4, be deformed into body that seal ring 4 and last bellmouth 5 and following bellmouth 6 be welded into and pipeline 7 until seal ring 4 and all seal and contact.
Claims (2)
1. one kind pair is held flexible sleeve; It is characterized in that: comprise the last bellmouth and following bellmouth that are cut into from face through the body central axis; The two ends of last bellmouth and following bellmouth are equipped with split flange; Be provided with the seal ring mounting groove in the two ends of last bellmouth and following bellmouth; Many circles seal ring along last bellmouth axially-aligned is installed in each seal ring mounting groove, and the outside at the last bellmouth and the two ends of following bellmouth is equipped with the differential of splitting that is connected with the split flange at the last bellmouth and the two ends of following bellmouth, splits differential and compresses seal ring.
2. according to claim 1 pair is held flexible sleeve, it is characterized in that: described upward bellmouth or following bellmouth are provided with pipe pressurized blocking-up interface.
