Flange type clamp suitable for socket type steel tube interface repair and leakage repair

Abstract

The invention discloses a flange type clamp suitable for socket type steel tube interface repair and leakage repair. The flange type clamp suitable for socket type steel tube interface repair and leakage repair is characterized in that a pipeline socket end sleeves a pipeline insertion end; the pipeline socket end is provided with a groove; a retainer ring sleeves the right side of the groove, anda hoop ring sleeves the left side of the groove; a gap is formed between the hoop ring and the outer wall of the pipeline insertion end; a pressure strip and a sealing rubber ring are sequentially sleeved in the gap; a pressing part sleeves the pipeline insertion end; the pressing part is inserted into the gap, and is connected to the pressure strip; the pressure strip is used for allowing the sealing rubber ring to be in sealing connection to the top end of the pipeline socket end; and the pressing part is fixedly connected to the retainer ring through a retainer ring bolt. The flange type clamp greatly reduces material weight, and reduces processing, so that the cost is reduced; an assembly type structure is adopted, so that weight of single component is reduced, and therefore, the flange type clamp can be manually carried in case of not having hoisting equipment on a construction site, and also reduces construction cost and needs on the hoisting equipment.

Description

technical field [0001] The invention relates to a flange-type fixture suitable for urgently repairing leaks at socket-type steel pipe joints. Background technique [0002] With the extensive use of socket-type spiral welded steel pipes and the increasing diameter of the pipes, cast iron socket pipes have gradually withdrawn from the water supply field. Due to the leakage problem caused by the damage or failure of the apron caused by improper operation during the installation and construction of the socket-type spiral welded steel pipe or other reasons, it is necessary to use a rush repair leak fixture to carry out the sealing operation. And the leak repair fixture used at present still follows the leak repair fixture that was used for the cast iron socket pipeline in the past. Due to the different forming principles of the two sockets, the size of the sockets has also changed. Although some trapping fixtures have also been adjusted in size to adapt to this change, the over...

Problems solved by technology

[0003] In order to adapt to the thick head of the cast iron socket pipe and the limitations of the technical conditions at that time, the original half-joint leak repairer was manufactured by casting. The casting of the shell parts made the half-joint leak catcher large in size and heavy in weight. Heavy

For leak traps for large-diameter pipelines, it is difficult to make, the weight is huge, the cost is high, and transportation and on-site construction are extremely inconvenient
