The liquid inlet/outlet adopts a ceramic hard seal structure, the liquid is in contact with the ceramic throughout the entire process, and does not touch the stainless steel jacket. The ceramic parts of the liquid inlet/outlet can be disassembled for cleaning and disinfection like the ceramic plunger rod and the ceramic reversing rod, which completely solves the problem of cleaning the dead angle between the steel jacket and the ceramic.

Manual arc welding shall be used for the welding between the rods of the portal scaffold, and other methods may be used to ensure the same strength. The welding of the vertical rod and the horizontal rod, and the welding of the screw, the insert tube and the bottom plate must be welded around. The height shall not be less than 2mm. The surface shall be smooth and smooth. There shall be no leakage welding, weld penetration, cracks and slag inclusions. The diameter of the weld pores shall not exceed 1.0mm, and the number of pores in each weld shall not exceed two. The meat depth must not exceed 0.5mm and the total length should not exceed 1.0% of the weld length.
The surface coating of the portal scaffold requires the portal scaffolding to be galvanized. The hooks of the connecting rod, locking arm, adjustable base, adjustable bracket and scaffolding, horizontal shelf and steel ladder shall be galvanized on the surface. The zinc surface should be smooth, with no burrs, dripping or excess clumps at the joints. The non-galvanized surfaces of the gantry and fittings should be painted, sprayed, or invaded with two anticorrosive paints and a top coat. Phosphorus can also be used. The paint should be uniform on the surface of the paint, without any defects such as paint leakage, runny, peeling, wrinkles, etc.
