Summary of the invention
The technical problems to be solved in the utility model provides a kind ofly can protect working life, the tap water delivery pipe flow control valve laborsaving, simple in structure, with low cost easy to use that lifting screw is indeformable, improve lifting screw.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of tap water delivery pipe flow control valve, comprise that two ends are provided with the connecting tube of adpting flange, the inside of described connecting tube is provided with the spool for the control flow, described connecting tube is provided with the lifting screw for the described spool of control, described connecting tube is provided with scaffold, the end of described scaffold is provided with the fixed plate that has through hole, and described lifting screw is sheathed to be positioned in the through hole of described fixed plate.
As further improvement in the technical proposal:
The end of described lifting screw is provided with rolling disc, described rolling disc is made up of hand-held annulus and Duo Gen connecting tendon, the axle center of the described many relative lifting screws of the connecting tendon layout that is centrosymmetric, described hand-held annulus link to each other with the end of lifting screw by many connecting tendons respectively.
Described connecting tube is provided with the positioning plate that has through hole, and described positioning plate is arranged between connecting tube and the fixed plate, and described positioning plate is mounted on the connecting tube by two connecting bolts, and described lifting screw is sheathed to be positioned in the through hole of described positioning plate.
The utlity model has following advantage: the utility model is in use as needing to transfer the flow control of realization tap water delivery pipe; then need by counterclockwise or clockwise rotate the folding degree that lifting screw comes regulating spool; in the lifting process of lifting screw; be positioned owing to lifting screw is sheathed in the through hole of fixed plate; can guarantee that lifting screw is always along axially rotating; thereby it is more laborsaving when regulating; and the screw thread that can prevent lifting screw is owing to regulating direction not to being damaged; this external without the time also can effectively protect in the lifting screw sheathed through hole that is positioned fixed plate the lifting screw can be not stuck owing to collision deformation, have and can protect lifting screw indeformable; improve the working life of lifting screw; easy to use laborsaving; simple in structure; advantage with low cost.
