The technical scheme of the utility model is that:
the utility model provides a pressure testing device of telescopic joint of two rubber seal, includes that the joint of two pipelines is the pipe joint, two the pipe joint is butted, two the outside of pipe joint is equipped with the sleeve, telescopic inboard both ends all are equipped with twice recess, be equipped with the rubber ring in the recess, sleeve, pipe joint, rubber ring constitute a seal structure, every end all be equipped with the pressure testing hole between the twice recess, the downthehole pressure testing mouth that is equipped with of pressure testing, the end of intaking of pressure testing mouth is located the telescopic outside, the play water end of pressure testing mouth is located telescopic inboard. By dividing a joint into two closed spaces, the tightness test of two ends of the joint is realized.
The inner diameter of the sleeve is matched with the outer diameters of the two pipeline joints, the sleeve and the two pipelines are made of the same material, and the sleeve can be made of glass fiber reinforced plastic materials.
The pressure testing nozzle is of a hollow structure.
And a sealing structure such as sealant is arranged between the periphery of the pressure testing nozzle and the sleeve.
During the piping erection, insert the pipe joint in the sleeve, seal through the compression of rubber ring between pipe joint and the sleeve, telescopic both ends are equipped with twice recess and twice sealed rubber ring respectively, let sleeve, pipe joint, rubber ring constitute a seal structure, such structure is connected both ends by independent realization respectively. Then, two small holes are drilled at corresponding positions on the sleeve, a pressure testing nozzle is installed on the sleeve through a sealing gasket and a fixing nut, the tightness between the pressure testing nozzle and the sleeve is ensured, the pressure testing nozzle is of a hollow structure, water can be injected into a closed space formed by the sleeve, a pipeline connector and a rubber ring from the hollow structure for pressure testing, the pressure is increased to 1.5 times of the working pressure, and then whether the structure formed by the sleeve, the pipeline connector and the rubber ring can meet the working condition requirement or not is tested.
By testing the closed parts at the two ends of the joint, the testing pressure can reach 1.5 times of the pressure grade, which means whether the sealing of the sleeve joint can be strictly verified in the actual installation process, thus ensuring that the success rate of one-time integral pressure test after the pipeline installation is finished can basically reach 100 percent, which has a revolutionary improvement on the safety and the rapidness of the whole project, and simultaneously has great popularization significance for the application of continuously winding the latest glass steel tube in the actual project, and can generate great social and economic benefits.
The utility model has the advantages that: the quick and simplified pressure test device for the pressure test of the sleeve joint is realized, the tested pressure can realize 1.5 times of the pressure grade, the defects of the prior art are fundamentally overcome, the joint of the continuous winding pipe is truly tested, and the method has great significance for the popularization of domestic continuous winding of the fiber reinforced plastic pipeline.
