Apparatus preventing deformation of co-used buffers

The utility model relates to a weld-quality guaranteeing apparatus for co-used buffers of a reciprocating compressor and specifically relates to an apparatus preventing deformation of the co-used buffers. The apparatus comprises a pedestal and connecting disks, wherein the connecting disk is arranged on the pedestal; the co-used buffers comprises an air inlet buffer and an air buffer; an air outlet on the air inlet buffer and an air inlet on the air outlet buffer are respectively corresponding to and connected with one connecting disk; and an installing distance of the connecting disks on the pedestal can be adjusted. A purpose of the apparatus is to prevent co-used buffers from generating stress deformation caused by full weld operation and to solve a problem that buffers cannot be installed even though stress is removed; assembling time and production cost are reduced; and product quality is guaranteed. The apparatus preventing deformation of co-used buffers fills gap of reciprocating compressor industry an
