18 is a cross-sectional view of the branching device 160 shown in an example of a state in which the branching hole 61 is inserted in the space portion 162 by sandwiching the transfer pipe 55 in which the branching hole 61 is drilled in both side branching holes. And the packing rings 179 and 183 and the backup rings 178 and 184 and the clamping rings 190 and 191 are fitted on the outer surface of the transfer pipe 55, 177 and 183 so that the inclined surfaces 177a and 183a are brought into close contact with the inclined surfaces of the packing engaging portions 169 and 171 and the backup grooves 170 and 172 are provided with the backup rings 178 The hexagonal caps 191 and 192 are coupled to the backup rings 178 and 184 by rotating the hexagonal caps 191 and 192 in the tightening direction after coupling the compression parts 181 of the fasteners 179 to the outside of the backup rings 178 and 184, The unit tube 161 is tightly fixed to the transfer pipe 55 to keep airtight and the branch pipe 193 is coupled to the branch pipe 173 formed at one end 167 of the branch unit 161 The fixed packing 183 is coupled The urging portion 186 of the fastener 184 pushes the rear surface of the packing 183 to be pressed and supported and then the hexagonal cap 193 is rotated in the tightening direction to tighten the branch tube 193 firmly to the projecting portion 167 The airtightness is maintained while being fixed and branching of the branch branch pipe 193 is achieved irrespective of the position of the branch hole 61 when the branch hole 61 is located in the space portion 162. [

Therefore, if the branch unit 161 is installed to face the predetermined direction, the branching direction can be set to a desired direction. 18, the fluid flowing in the inlet (N direction) through the transfer pipe 55 flows into the outlet (O direction) of the transfer pipe 55, and a part of the fluid flows through the branch hole 61 The fluid branching in the P direction is achieved while flowing to the branch branch pipe 193 after flowing out into the space portion 162. [

Since the present invention is a structure that surrounds the outside of the transfer pipe 55, it can be fastened in the direction to be branched regardless of the direction of forming the branch hole, so there is no great limitation on the direction and length of the branch pipe.

According to the present invention, since the branch hole formed in the transfer pipe (55) can be processed in a safe place, the workability is excellent and the work is simple, safety accident is prevented, branching cost can be reduced, Work is possible.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.

Therefore, the scope of the present invention should not be construed as being limited to the embodiments described, but should be determined by equivalents to the appended claims, as well as the appended claims.
