AI Technical Summary
Existing long-term hydrostatic pressure testing equipment for FRP pipes is prone to problems such as loosening of the connection between the seal and the pipe under high pressure, resulting in unstable connection.
The system adopts a threaded connection method, which drives the relative movement of the first and second sealing seats through the transmission rod and the threaded sleeve. Combined with the step and sealing ring design, it ensures a stable connection between the sealing seat and the pipeline, and conducts a long-term hydrostatic pressure test through the pressure-pressurizing assembly.
This achieves stability and convenience in the connection between the sealing seat and the pipeline, ensures airtightness, avoids the loosening problem of traditional detachable connection methods, and improves the reliability of the test.
