link to yihyeonggwan of manhole pipe line equipment

摘要

Connect device to yihyeonggwan of manhole pipe line is designed for 300, pahyeonggwan 320 on the inside fitted with gwanrogu body 310 having an internal structure which may overlap with each other, pahyeonggwan gwanrogu body is fitted to the inside of the right and left direction so as not to move to a plurality of fixed wedge gwanrogu for securing the body 350 and the one side is gwanrogu close contact with the outer surface of the adapter body and the other end having a predetermined size and a stepped outer diameter so that the close contact with the outer surface of the inner structure pahyeonggwan rubber tube 330, and the adapter in the longitudinal direction of the tube forms a part gatdoe surrounding the outer peripheral surface of the rubber tube has a spaced-sectional structure at a predetermined interval is configured in the adapter band 340 has a structure which can be screwed with the internal diameter narrowing along the two sides of the incision. Some minutes of this invention is to wrap around the body and pahyeonggwan gwanrogu gwanrogu are overlapped with each other and overlap overlaps between the adapter body and pahyeonggwan rubber tube, by tightening while wrapped rubber tube into the outer circumferential surface of the adapter, the adapter band, gwanrogu body and pahyeonggwan and adapter while completely blocking the gap between the rubber tube to be structurally stable gwanrogu pahyeonggwan the body and can be fixed to each other. ;
