The second helical blade is coaxially fixed on water conservancy diversion inside pipe wall, second helical blade is cylinder；
Screw shell is also screwed on the diversion pipe, the barrel of the screw shell is equipped with stepped hole, the stepped hole
Include threaded hole and perforation successively from outside to inside, the perforation is identical with the through-hole diameter, and the screw shell is screwed to its end
When face is contacted with the baffle, the perforation is coaxial with the through hole；
Plug screw is further included, the plug screw includes thread segment and optical axis section, and the thread segment coordinates with the threaded hole, described
Optical axis section is stretched into after sequentially passing through the O-ring being embedded on the perforation and through-hole wall in the diversion pipe, the O-ring and institute
It states optical axis section and squeezes contact.
Further, the taper of first helical blade is 23~28 degree.
Further, it is hemispherical to stretch into one end in diversion pipe for the optical axis section.
Further, the nut cylindrical surface of the plug screw is equipped with several fins.
Further, the cross section of first helical blade and the second helical blade is identical and is in crescent.
Further, the port of export of the diversion pipe also connects there are one coniform nozzle, and the end face of the nut is fixed
There is handwheel.
The beneficial effects of the utility model：The utility model is stablized using conical tube and the first coniform helical blade
Mortar is conveyed, mortar is made to be sprayed along pipe wall screw, slip casting is stablized, and will not directly be sprayed and be spilt as ordinary straight pipeline section.Separately
Outside, the variation to diversion pipe bore is realized by special plug screw, plays the role of a regulating valve, it is ingenious to be threaded set
The pipe thickness needed for diversion pipe is reduced, is positioned by baffle, ensures that perforation and through hole can reach together when being screwed to bottom
Dynamic sealing so that optical axis passes through, is realized in the position of axis face；So as to effectively adjust mortar uninterrupted and with two helical blades
Cooperation, slip casting, adaptability are extremely strong with realizing stable, adjustable flow.
