Curve push pipe tube coupling bell and spigot connection form

The utility model provides a curve push pipe tube coupling bell and spigot connection structure, tube coupling bellmouth, tube coupling socket all adopt steel sheet processing preparation, and bellmouth structure circle is formed by the steel sheet system of rolling up, the one end parallel and level of bellmouth structure circle, and the other end sets up big groove, the parallel and level end of bellmouth flange and bellmouth structure circle, tube coupling weld each other, and the welding has the bellmouth floor of putting more energy into on the terminal surface of bellmouth flange, and middle the reservation has the bolt hole, establish the twice recess on the socket structure recess of tube coupling socket, socket structure recess welds on the socket flange, the welding has the socket floor of putting more energy into on the terminal surface of socket flange, and middle the reservation has the bolt hole, be equipped with wooden backing plate between bellmouth flange and the socket flange, align fixedly through the bolt hole of spacing bolt on with the bellmouth flange and the bolt hole level on the socket flange, being equipped with twice stagnant water rubber circle in the twice recess on the socket structure recess of tube coupling socket and carrying on waterproofly, it does not ooze the tightness to ensure that tube coupling junction hermetic seal reaches. This structure safety, reliable, high efficiency, economy, practicality.
