Abstract

A bridge concentric continuously adjustable water regulator comprising: an outer tube; an adjusting sleeve disposed in the outer tube; a concentric valve connected below the adjusting sleeve, with a center of circle of the concentric valve being concentric to the outer tube; a water outlet which runs through a side wall of the outer tube and is connected to the concentric valve; a lower sealed section which is disposed in the outer tube and is below the concentric valve and the water outlet; and a bridge passage disposed in the side wall of the outer tube and outside the concentric valve and the lower sealed section.

First claim

The invention claimed is:

1. A bridge concentric continuously adjustable water regulator, comprising:
an outer tube;
an adjusting sleeve disposed in the outer tube;
a concentric valve connected below the adjusting sleeve, with a center of the concentric valve being concentric to the outer tube, wherein the concentric valve comprises a ceramic valve core and a ceramic valve sleeve disposed outside the ceramic valve core, and wherein a lower part of the ceramic valve core is provided with a linear V-shaped opening;
a water outlet which runs through a side wall of the outer tube and is connected to the concentric valve;
a lower sealed section disposed in the outer tube and located below the concentric valve and the water outlet; and
a bridge passage disposed in the side wall of the outer tube and outside the concentric valve and the lower sealed section.

2. The bridge concentric continuously adjustable water regulator according to claim 1 , further comprising a lower joint connected below the outer tube, wherein the lower joint connects the bridge passage and the lower sealed section.

3. The bridge concentric continuously adjustable water regulator according to claim 1 , wherein the outer tube comprises an upper outer tube and a lower outer tube, which are in threaded connection.

4. The bridge concentric continuously adjustable water regulator according to claim 3 , further comprising a locating sleeve disposed in the upper outer tube, the locating sleeve being above the adjusting sleeve.

5. The bridge concentric continuously adjustable water regulator according to claim 4 , wherein the adjusting sleeve and the concentric valve are both in the lower outer tube.

6. The bridge concentric continuously adjustable water regulator according to claim 4 , wherein, the locating sleeve is in the upper outer tube, and an upper end of the locating sleeve has a four-penpoint locating structure which includes four finger-like components that are arranged at intervals and have different heights.

7. The bridge concentric continuously adjustable water regulator according to claim 4 , further comprising an upper sealed section disposed in the lower outer tube, the upper sealed section being connected above the adjusting sleeve and below the locating sleeve.

8. The bridge concentric continuously adjustable water regulator according to claim 1 , further comprising an upper joint connected above the outer tube.

9. The bridge concentric continuously adjustable water regulator according to claim 1 , further comprising four water outlets which uniformly run through the side wall of the outer wall and sixteen bridge passages arranged circumferentially, wherein four bridge passages are distributed uniformly between two adjacent water outlets.
