Detailed Description
As shown in fig. 1 and 2, the special blind plate for multi-pipe-diameter pipeline pressure testing provided by the utility model comprises a fixed plate 1 and a cover plate 2, wherein the fixed plate 1 comprises two symmetrical clamping plates 3, bolt holes 7 are arranged at two ends of the clamping plates 3, an arc-shaped clamping opening 4 is arranged at the inner side of the clamping plates 3, and the arc-shaped clamping opening 4 is matched with the pipeline; two ends of the arc-shaped clamping opening 4 are provided with locking clamps 5; one end of the locking clamp 5 is fixed on the clamping plate 3, and the other end is provided with a locking hole 6; the middle of the cover plate 2 is provided with a sealing rubber gasket 9, the two ends of the cover plate 2 are provided with adjusting holes 8, and the adjusting holes 8 are matched with the bolt holes 7.
As shown in figure 3, the utility model discloses when using, at first with arc clamp mouth 4 and pipeline 11 looks adaptation, arc clamp mouth 4 clamps in the pipeline 11 both sides of the flange lower extreme that the pipeline end that the pipe diameter is different set up. The locking bolt passes through the locking hole 6 to assemble and fix the two symmetrical clamping plates 3 together on two sides of the pipeline 11. The cover plate 2 is then placed over the flange 10 at the end of the pipeline, with the sealing rubber mat 9 covering the flange 10. Finally, the fixing bolt penetrates through the adjusting hole 8 and the bolt hole 7 to fix the fixing plate 1, the cover plate 2 and the flange 10 together.
The arc-shaped clamping opening 4 is internally provided with a gasket which is a soft rubber sheet or a soft plastic sheet laid on the arc-shaped clamping opening 4. The two symmetrical clamping plates 3 can be tightly fixed together to fix a pipeline with a smaller pipe diameter, and a smaller locking bolt can be used to penetrate through the locking hole 6 to assemble the two symmetrical clamping plates 3 together to be fixed on two sides of the pipeline 11. Correspondingly, when the fixing bolt penetrates through the adjusting hole 8 and the bolt hole 7, the fixing bolt is fixed in the middle position of the inner end of the adjusting hole 8, and the fixing plate 1, the cover plate 2 and the flange 10 are fixed together. A certain gap can be left between the two symmetrical clamping plates 3 for fixing the two symmetrical clamping plates 3 together, for example, 20-30mm can be left between the two symmetrical clamping plates 3 for fixing the pipeline with larger pipe diameter, and a larger locking bolt can be used to pass through the locking hole 6 to assemble the two symmetrical clamping plates 3 together and fix the two symmetrical clamping plates 3 on the two sides of the pipeline 11. Correspondingly, when the fixing bolt penetrates through the adjusting hole 8 and the bolt hole 7, the fixing bolt is fixed at two ends of the adjusting hole 8 to fix the fixing plate 1, the cover plate 2 and the flange 10 together.
The diameters of the flanges 10 are different due to the different diameters of the pipelines 11 such as water pipes, oil pipes and the like. The utility model discloses a relative distance between the splint 3 of two symmetries comes the adaptation to clamp 11 both sides of pipeline that the pipe diameter is different. Through the different positions of fixing bolt in regulation hole 8, make fixing bolt run through regulation hole 8 and bolt hole 7 simultaneously, will be in the same place fixed plate 1, apron 2 and flange 10 three are fixed, and need not to change the blind plate of changing different models according to the pipe diameter is different two, can carry out pressure test for pipelines 11 such as different water pipes of pipe diameter, oil pipe.
According to above-mentioned operation, will need to use through the one end of pipelines 11 such as water pipe, oil pipe that carry out pressure test the utility model provides a special blind plate is pressed in multitube footpath pipeline examination, live it is sealed. And the other end of the pipeline 11, such as a water pipe, an oil pipe and the like, which needs to pass through the pressure test needs to be connected with a pressurizing pump. Therefore, the middle of the cover plate 2 is provided with a pressing hole 20, and the pressing hole 20 is matched with a pressing hose of a pressing pump. The inner thread is arranged in the pressing hole 20, the threaded interface at the front end of the pressing hose is provided with the outer thread, the inner thread is matched with the outer thread, and the pressing hose of the Wirtte manual 70kg pressing pump is directly and fixedly connected to the pressing hole 20 to perform a pressing test.
