Abstract

배수회로의 하류단부에 설치한 배수관 접속부(76)내에 슬리브(9)를 하류단부 개방부로부터 삽입함과 함께 이 슬리브(9)에 역류방지용의 밸브체(94)를 장착시킨 역류방지기구에 있어서, 슬리브(9)의 외주와 배관접속부(76)를 밀폐하기 위한 특별한 밀폐부재를 필요로 하지 않으므로서 구조의 간략화와 조립작업의 효율화를 도모하려고 한다.In the backflow prevention mechanism in which the sleeve 9 is inserted from the downstream end opening in the drain pipe connecting portion 76 provided at the downstream end of the drain circuit, and the valve body 94 for preventing backflow is attached to the sleeve 9. Therefore, it is intended to simplify the structure and the efficiency of assembly work without requiring a special sealing member for sealing the outer circumference of the sleeve 9 and the pipe connecting portion 76.

배수관 접속부(76)의 전기 슬리브 수용부의 상류단부에는 환상벽(78)을 중심방향으로 돌출시켜서 그 하류측 벽면을 밸브시트부로서 그 밸브시트에 밸브체(94)를 대접시키고 이 밸브체(94)는 이것의 주연의 일부에 연설된 부착대(95)와 함께 고무등의 탄성재료에 의하여 일체형성되며 이 부착대(95)의 선단부를 슬리브(9)와 배관접속부(76)의 사이에 지지시키며 슬리브(9)를 배관접속부(76)에 이탈방지상태로 결합시켰다.At the upstream end of the electrical sleeve accommodating portion of the drain pipe connecting portion 76, the annular wall 78 is projected in the center direction, and the valve body 94 is welded to the valve seat as the valve seat with the downstream wall surface thereof. ) Is formed integrally by an elastic material such as rubber together with the mounting table 95 protruded to a part of its periphery, and supports the tip of the mounting table 95 between the sleeve 9 and the pipe connecting portion 76. The sleeve 9 is coupled to the pipe connecting portion 76 in a separation prevention state.
