Packaging and transportation box and packaging method for casting valve

Abstract

The invention discloses a packaging and transportation box and a packaging method for a casting valve. The packaging and transportation box comprises a box body, a box cap, an upper protective shell and a lower protective shell. The bottom of the lower protective shell is connected with the box body through a first airbag belt. The other two side faces of the lower protective shell and the upper protective shell are each bonded with a second airbag belt through glue. The casting valve packaged through foam is put into a lower casting valve storage cavity of the lower protective shell. Tape is adopted for layer-upon-layer winding along the peripheries of the upper protective shell and the lower protective shell. According to the packaging and transportation box and the packaging method for the casting valve, the casting valve is wrapped with the foam and then put into the upper protective shell and the lower protective shell which are made from foam boards, and layer-upon-layer winding is conducted through the tape so that the casting valve can be avoided from separating from the upper protective shell and the lower protective shell, and the peripheries of the upper protective shell and the lower protective shell are partitioned from the box body and the box cap through the first airbag belt and the second airbag belts, so that the casting valve is completely packaged and avoided from being damaged due to collision in transportation.

Description

technical field [0001] The invention relates to the packaging field of casting valves, in particular to a packaging transport box and a packaging method for casting valves. Background technique [0002] Casting valves are valves formed by pouring. Casting valves can be used to make valves with complex shapes, and the manufacturing cost is low, and the equipment cost is also low, so it is used by more and more manufacturers. [0003] However, the casting valve has a disadvantage that the carrying capacity is not as good as that of the forging valve, so care must be taken during packaging and transportation, because the current casting valves often break due to lack of protection during transportation. After damage, it can only be scrapped, so the packaging protection before transportation is extremely important. Contents of the invention [0004] The object of the present invention is to provide a packaging transport box and a packaging method for casting valves, which hav...
