Abstract

본 발명은 유압기 사이이 유로를 연결하는 관이음쇠의 나사축 중간에 나사축의 외경보다 약각 외경이 적은 직선부를 형성하여 이 직선부에 와셔가 끼움되어 이의 통공이 직선부에 밀접되게 하는 와셔의 끼움장치에 관한 것이다. 종래의 유압기 등의 관이음쇠는 이의 나사축에 와셔를 끼움함에 있어 와셔의 통공이 나사축의 외경부가 약간 크게 하여 끼움하였던 관계로 끼움된 와셔는 단순히 압의 전달 구실만 하고 밀폐구실을 할수 있어 저압의 경우에도 누압되는 결점이 있었던 것이다. 본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명 요지는 관이음쇠몸체(1)의 나사축(2)의 중간부에 나사축(2)의 외경보다 약각 적고 좁은 공간부를 가진 직선부(3)을 형성하고 통공(4A)이 나사축보다 약간 크고 경사면(4')을 가진 와셔(4)가 나사축(2)에 끼움된 후 상하금형(7)(9)을 이용하여 와셔의 경사부(4')를 압착하여 평평한 판면이 되게 하면 이때 와셔(4)의 통공(4A)이 축쇠되면서 직선부(3)에 밀접되어지게 하므로서 이를 유입기의 유로에 체결하였을 때는 와셔(4)는 쌍구실과 오링 구실을 겸용하여 상당한 고압에도 견딜수 있게 한 것이다.The present invention is characterized in that a straight portion having a small outer diameter smaller than the outer diameter of the screw shaft is formed in the middle of the screw shaft of a pipe fitting connecting the hydraulic oil passage and the washer is fitted in the linear portion so that the through- . In the conventional pipe fitting of a hydraulic machine or the like, since the washer is inserted into the screw shaft thereof, the outer diameter portion of the screw shaft is slightly larger than the through hole of the washer, so that the washer fitted therein can merely transfer the pressure, Even if there was a drawback that pressure was leaked. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a pipe fitting body in which a straight portion 3 having a space smaller and narrower than the outer diameter of the screw shaft 2 is provided at an intermediate portion of the screw shaft 2, And the washer 4 having the inclined face 4 'is inserted into the screw shaft 2 after the through hole 4A is slightly larger than the screw shaft and then the upper and lower molds 7 and 9 are used to fix the inclined portion The washer 4 is tightened and tightly fitted to the straight portion 3 so that the washer 4 is screwed into the twin threaded portion when the threaded portion is fastened to the flow path of the inflow portion. O-ring is used as well, so that it can endure considerable high pressure.
