Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig. 1 and Fig. 2, one kind disclosed by the utility model is capable of the advanced tubule of anti-backflow, including circular
Tube body 1 and tube head 11 positioned at 1 length direction one end of tube body.Tube head 11 is integrally formed in cone and with tube body 1.Tube body
It is additionally provided on 1 tube wall and the integrally formed flange 13 of tube body 1.Flange 13 is away from the end face of tube head 11 and tube body 1 away from pipe
There are spacing for first 11 one end.Several connection tube bodies 1 are offered on the tube wall of tube body 1 between flange 13 and tube head 11
Inside and outside slurry outlet 12.
The rubber pad 5 of annular is bonded on end face of the tube body 1 away from tube head 11.The size of rubber pad 5 and the pipe of tube body 1
Mouth size is adapted.Raw material band 4 is also wound on the outer tube wall between 11 one end of tube head positioned at flange 13 and tube body 1.
The side of tube head 11 is provided with the sleeve 2 being slidably connected with tube body 1 in tube body 1.Sleeve 2 is cylindrical, set
The internal diameter of cylinder 2 is consistent with the outer diameter of tube body 1.The axis of sleeve 2 is overlapped with the axis of tube body 1.Sleeve 2 is towards one end of tube body 1
