a pipe combine device of heat exchanger for cooling distilled water

摘要

The present invention can easily disassemble and assemble the distilled water flow pipe of the heat exchanging device for distilled water cooling and the second cooling water flow pipe installed on the outer surface of the distilled water flow pipe, It is possible to easily extend the service life of the heat exchanging device for cooling the distilled water and also to prevent cracking and breakage of the distillated water flowing pipe between the first and second cooling water flowing pipes And more particularly to a pipe coupling device for a distilled water cooling heat exchanger. The technical constitution is such that a distilled water flow pipe 130 installed on the outer surface of the first cooling water flow pipe 110 of the heat exchanger 100 for distilled water cooling and a second Through holes 211 corresponding to the outer surface of the first cooling water flow pipe 110 or through holes 211 corresponding to the outer surfaces of the distilled water flow pipe 130 are formed in the respective ends of the cooling water flow pipe 150 And a threaded portion 220 is formed on the outer surface of the coupling hole 210. The coupling hole 210 is formed in the inner front side so as to be coupled with the threaded portion 220 of the coupling hole 210 The inner space 242 of the nut portion 240 is formed with the female thread portion 230 and the rear end portion of the nut portion 240 is formed with the space portion 242 inside the nut portion 240 where the locking protrusion 241 is formed, The inner surface of the first cooling water flow pipe 110 or the distilled water flow pipe 130, And a gasket 250 of a predetermined shape which is in close contact with the rear end of the gasket 250 is installed so as to be movable in the left and right direction and is fixedly attached to the rear end of the coupling hole 210.
