Detailed Description
The present utility model will be described in detail with reference to the embodiments shown in the drawings.
The utility model is used for temporary rush repair when the conditions of pipeline medium leakage, corrosion, perforation and the like occur. The pipeline pressure is required to be not more than 15MPa, the working temperature is between minus 20 ℃ and 120 ℃, and the pipeline specification phi 114-phi 1422mm is applicable.
The utility model relates to a lengthened deep cavity split type pipeline rush-repair fixture which comprises a self-sealing upper guard plate, a self-sealing lower guard plate, a fastening bolt, a nut, a sealing rubber strip and a bolt stretcher. The annular sealing rubber strips and the longitudinal sealing rubber strips are arranged in the corresponding rubber strip grooves; the annular sealing rubber strip and the longitudinal sealing rubber strip are fixed in the rubber strip groove through the toothed pressing plate and the longitudinal pressing plate, so that loosening and falling are avoided, and meanwhile, the sealing function is not affected. The upper guard plate and the lower guard plate of the self-sealing guard plate clamp body are tightly connected through a plurality of fastening bolts and nuts. And a bolt stretcher fastening mode is adopted to realize quick installation of the clamp.
Examples
The annular sealing rubber strips 6 and the longitudinal sealing rubber strips 7 are made of nitrile rubber, and are embedded in a sealing groove processed by a guard plate. The function is that the guard board is extruded to form a sealing cavity; the tooth-shaped pressing plate 5, the transverse pressing plate 8 and the vertical pressing plate 9 are welded on the guard plate and play a role in limiting the sealing rubber strip; the supporting blocks 16 are welded on the guard plates, and when the upper guard plates and the lower guard plates are combined, the gap between the supporting blocks 16 is 3-4mm; the spindle screw 11 acts to rotate the shield; the supporting block 16 and the supporting bolt 17 are connected by threads to adjust the size of the opening between the guard plates; the retainer ring 14 is used for limiting the supporting block 16; the fastening bolt 3 and the fastening nut 4 have the function of generating extrusion force on the guard plate, so that the guard plate forms a sealing cavity.
When the clamping device is operated, the upper guard plate and the lower guard plate are firstly arranged on a pipeline, and then the sealing rubber strips in the clamping device are mutually extruded through the fastening bolts and the nuts to form a sealing cavity, so that the sealing effect of the clamping device is achieved.
1. Before the fixture is installed, foreign matters such as an anticorrosive coating, rust and the like on the surface of the pipeline are removed.
2. The ovality of the pipeline is detected, and the sealing gasket permits the surface of the pipeline to have smaller irregularities, which are within 0.8 mm.
3. And uniformly coating lubricant on the surface of the sealing rubber strip of the fixture.
4. The clamp is clamped on the pipeline so that the two ends coated with the yellow paint are opposite, and the clamp is placed at the center of the pipeline breaking point as much as possible. Sometimes, it is more convenient to first loosen the clamp on one side of the pipeline breaking point and then move to the center of the breaking point.
5. And installing bolts and nuts, and uniformly tightening the nuts sequentially from the middle to the two ends of the fixture. The same torque of each bolt is ensured.
6. When the fixture is completely fixed, the gap between the upper guard plate and the lower guard plate is 4-5 mm.
7. After confirming that the clamp is leak-free, the pressure is maintained for 30 minutes, and welding can be performed. Note that: the sealing gasket is not overheated during welding. And different parts are welded in sequence, so that heat concentration is avoided. In field welding, bolts, nuts must be tightened at regular intervals, as the welding may cause loosening.
