The utility model discloses a high-strength copper elbow pipe fitting, which relates to the field of elbow pipe fittings and comprises a pipe body, internal threads are arranged on the inner walls of pipe orifices at two ends of the pipe body, a cleaning component is mounted in the pipe body, connecting components are mounted on the peripheries of the pipe orifices at two ends of the pipe body, and the cleaning component comprises a cleaning hole. The cleaning hole is formed in the bottom end of a bent opening of the pipe body, a first thread is arranged on the outer wall of the cleaning hole, a sealing cover is connected to the periphery of the first thread, a first screw groove is formed in the inner wall of the sealing cover, and a sealing plug is installed at the position, located in the cleaning hole, of the top of the sealing cover. Two positioning seats are fixedly mounted on the periphery of the sealing cover, the first screw groove and the first thread are in threaded connection, and the sealing plug is located in the cleaning hole and matched with the cleaning hole; the internal sealing is improved, cleaning and inspection of the interior of the pipe body are facilitated, meanwhile, the smoothness of the inner wall is improved, and the pipe is suitable for an internal thread and external thread connection mode.

The chemical processing tank convenient to sample comprises a tank body, the top end of the tank body is movably connected with a tank cover, the bottom end of the tank body is fixedly connected with supporting legs, the bottom end of one side of the tank body is fixedly connected with a liquid outlet valve, and the liquid outlet valve is communicated with the interior of the tank body. According to the chemical processing tank convenient to sample, through the arrangement of a handle, a cover plate, a connecting column, a rubber plug, a sampling barrel, a liquid guide valve and a liquid guide pipe, in the processing process, the cover plate can be pulled to rise through the handle after the liquid guide valve is opened, and the cover plate drives the rubber plug to rise through the connecting column; when the rubber plug is lifted, materials in the tank body are pumped out through air pressure in the sampling barrel and guided into the sampling barrel through the liquid guide pipe, the liquid guide valve is rapidly closed, the materials are left in the sampling barrel, then the rubber plug is taken out, sampling can be conveniently conducted in the sampling barrel, rapid sampling can be achieved, and the sampling efficiency is improved. The problem that sampling is not convenient is solved.

The utility model relates to the field of anti-freezing doors, in particular to a high-sealing-performance anti-freezing door for a refrigeration house. The technical problems that an anti-freezing door is directly attached to a sealing strip, due to the influence of external water vapor, a sealing structure of the anti-freezing door is aged, cold air is guided into the anti-freezing door, and the overall protection effect is reduced are solved. According to the technical scheme, the high-sealing-performance anti-freezing door for the refrigeration house comprises an anti-freezing door assembly, a lateral sealing installation assembly, a top sealing installation assembly and a bottom sealing installation assembly; peripheral sealing protection is formed through the lateral sealing mounting assemblies located on the two sets of the anti-freezing door assembly, the top sealing mounting assembly and the bottom sealing mounting assembly, effective mounting operation is carried out, the leakage condition is avoided, multiple sets of isolated sealing are formed through the aluminum alloy partition plates, the gap between the roller shutter sealing plate and the anti-freezing door assembly is reduced, and the service life of the roller shutter is prolonged. And the internal sealing performance is improved.
