The invention discloses a pressure testing method for a groove type pipe fitting, and the method comprises the steps: employing a pressure testing tool for the groove type pipe fitting to test the pressure of a to-be-tested pipeline, enabling the pressure testing tool for the groove type pipe fitting to comprise a connecting ring, two clamping sleeves, a sealing end cover and a high-pressure ball valve, enabling the connecting ring to sleeve the pipeline, and enabling the sealing end cover to be buckled on a port of the pipeline; then mounting the two clamping sleeves on the pipeline, wherein the two clamping sleeves are in butt joint together, at the moment, the sealing end cover is clamped in an arc-shaped clamping groove formed by the clamping sleeves, and meanwhile the arc-shaped ribs are clamped in the corresponding grooves; rotating the connecting ring, so that the connecting ring is in threaded connection with the outer parts of the two clamping sleeves after being connected; and finally, connecting the high-pressure ball valve to the connecting port in a sealed mode, and controlling high-pressure water to flow in and out through the high-pressure ball valve. The structural form of the pressure testing tool for the groove type pipe fitting is simplified, an operator can conveniently and rapidly complete assembling, and therefore the testing efficiency is improved.
Description
technical field [0001] The invention relates to the field of mechanical technology, in particular to a pressure testing method for grooved pipe fittings. Background technique [0002] The transmission pipeline is widely used as a transmission tool for long-distance transportation of liquid or gas. The transmission pipeline is formed by connecting multiple steel pipes, and the two steel pipes are connected by connectors. valve. The steel pipes and the steel pipes and the valves are usually connected by pipeline sealing connectors (such as CN210800309U). However, steel pipes or valves usually require a pressure test before they are used. Taking the steel pipe as an example, the two ends of the steel pipe are connected with the test tool through the pipe sealing connector to ensure the airtight connection, and then the high-pressure liquid is injected into the steel pipe. However, during the connection operation, it is necessary to complete the assembly of the sealed connect...
