Description

Technical Field

[0001] The utility model relates to the technical field of pipe testing equipment, in particular to a hydraulic test box for a steel wire skeleton composite pipe. Background Art

[0002] Steel wire skeleton composite pipe is a special pipe, usually used in industrial applications that withstand high pressure; hydraulic test is an important step to check the sealing performance, strength and pressure resistance of pipes; currently, when hydraulic testing steel wire skeleton composite pipes, two sealing covers are first fixedly installed at both ends of the pipe body, one of which is provided with a liquid injection port and a pressure measuring port connected to the inside of the pipe body. When measuring the pressure, the pipe body is first filled with liquid to avoid the presence of air inside the pipe body, and then pressurized to gradually increase the pressure of water or other liquids in the pipe. During the pressure increase process, observe whether the pipe has obvious deformation, leakage or other defects, and record the pressure value and time; pressure maintenance test: after reaching the set pressure, maintain the pressure for a period of time to check whether the pressure drops; and after the pressure maintenance test is completed, if the pipe body is qualified, the pipe body will be continuously pressurized to test the maximum pressure value that the pipe body can withstand;

[0003] At present, in order to avoid the leakage of the pipe body during the pressure measurement of the pipe body, the pipe body is usually placed in a test box for pressure measurement. For example: Figure 6 A steel wire skeleton composite pipe hydraulic test box in the prior art is shown, comprising a box body with an open top, a box cover for sealing the open end thereof is hinged on the box body, an electric cylinder hinged to the box cover is hinged on the box body, a water injection pipe and a pressure measuring pipe are fixedly installed on one side of the box body, the pressure measuring pipe is connected to an external pressure measuring device, and one end of the water injection pipe and the pressure measuring pipe are extended into the box body; when the pressure of the pipe body is measured, two sealing covers are fixedly installed on both ends of the pipe body, and the pipe body with the two sealing covers is manually moved into the box body, so that the water injection pipe and the water injection port are used to inject water into the pipe body, and then the pressure measuring pipe is connected to the pressure measuring port to pressurize the pipe body, so as to achieve the effect of hydraulic pressure test on the pipe body. Although this method can perform hydraulic pressure test on the pipe body, it still has the following defects in actual use:

[0004] When measuring the pressure of the pipe body, the staff needs to manually move the pipe body with two sealing covers into the box. After the pressure measurement is completed, the staff needs to manually move the pipe body out, which increases the workload of the staff.
