Problems solved by technology
If the bonnet thread of the plug valve is severely corroded, sand particles are stuck on the threaded connection part, or the bonnet is deformed under pressure, etc., it will take time and effort to disassemble the bonnet.
The whole process requires manual handling, especially for large-diameter plug valves, whose weight can reach more than 200 kilograms. The labor intensity is very high, the work efficiency is low, and the quality of inspection and maintenance is affected.

The invention relates to a complete device suitable for maintenance and repair work of plug valves. A feeding and discharging module is used for grabbing a plug valve to be detected; a conveying device is arranged between the two modules and used for conveying the plug valve; a dismounting module is used for dismounting a valve element and a bonnet, and a cleaning module is used for cleaning the plug valve; a detection module is used for carrying out magnetic powder detection on the plug valve; a maintenance and assembling module is used for reassembling the maintained plug valve with a hydraulic control system 7 and used for controlling hydraulic cylinders and hydraulic motors in all the modules; and all the functional modules can be used independently and can also be used in a combined mode. According to the complete device, manual carrying is not needed in the links of conveying, dismounting, cleaning and detecting, the maintenance and repair process is standardized, the labor intensity is greatly reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of cock valve inspection and maintenance, in particular to a complete device and operation method suitable for cock valve inspection and maintenance operations. Background technique [0002] The plug valve is the core component of the cementing and fracturing operation. It is used to control the transportation of sand liquid. Its working pressure is generally between 35MPa and 140MPa, and its diameter ranges from 2 inches to 4 inches. According to the standard, it needs to be inspected and repaired after it has been used in the well for a period of time. Traditionally, the inspection and maintenance procedure for in-service plug valves is to first fix the union joint of the plug valve on the column, then use a special disassembly tool to open the valve cover of the plug valve, pull out the valve core, clean, inspect, and finally replace it. Parts and assemblies. If the bonnet thread of the plug valve is se...
