Abstract
The utility model discloses a leakproof rotating shaft sleeve, wherein a groove is annularly arranged in the inner wall of the shaft sleeve and conducted with the outside through a drain opening. The utility model also discloses a water-powered alarm with the leakproof rotating shaft sleeve, comprising an impeller, an impeller shaft, an impeller shell and the shaft sleeve; the shaft sleeve is arranged at the outer side of the impeller shell; the impeller shaft is arranged in the impeller shell; one end of the impeller shaft is provided with the impeller, and the other end of the impeller shaft sequentially passes through the impeller shell and the shaft sleeve; the inner wall of the shaft sleeve is annularly provided with the groove; and the groove is conducted with the impeller shell through the drain opening. When the water-powered alarm with the leakproof rotating shaft sleeve is used, water enters the impeller shell and strikes the impeller, a small part of pressure water on the impeller enters the groove along a clearance between the impeller shaft and the impeller shell and converges into the impeller shell after flowing through the drain opening and is discharged. The shaft sleeve and the impeller shell are respectively provided with the large and wide enough groove and the drain opening, so that leakage water entering the shaft sleeve is stopped from continuously and outwards leaking along an axis. In addition, the water-powered alarm with the leakproof rotating shaft sleeve has the advantages of simplicity in machining, low machining precision requirement, no need of easily-damaged O-shaped rings and more convenience in maintenance.
Description
Technical field
The utility model relates to a kind of anti-leak rotary sleeve, particularly relates to a kind of warning water system with anti-leak rotary sleeve.
Background technique
As shown in Figure 1, existing warning water system mainly comprises impeller 1 ', impeller shaft 2 ', impeller housing 3 ', axle sleeve 4 ', bell clapper 5 ' and bell lid 6 '.The bottom of impeller housing 3 ' is provided with drain opening 32 ', the other end is provided with water intake 31 ', the arranged outside axle sleeve 4 ' of impeller housing 3 ', impeller shaft 2 ' is arranged in the impeller housing 3 ', one end of impeller shaft 2 ' is installed impeller 1 ', the other end is installed bell clapper 5 ' after passing successively impeller housing 3 ' and axle sleeve 4 ', and bell clapper 5 ' outer cover is established bell lid 6 '.
Drain opening 32 ' vertically down during installation, the alarm pressure current are through the water intake 31 ' of impeller housing 3 ', press water is injected in impeller 1 ' is rotated, 2 ' the rotation of impeller 1 ' impeller axle then makes bell clapper 5 ' rotation impact at bell lid 6 ' and sends alarm sound, reach the purpose of warning.Backwater enters the ditch from the drain opening 32 ' of impeller housing 3 '.
But the general structure that adopts single axle sleeve discharge opening of this warning water system, it can not reach the purpose of anti-leak.Particularly, the axis hole at impeller housing 3 ' arranges a discharge opening 33 '.When warning water system was worked, the small part backwater that impacts at impeller 1 ' leaked to the bell clapper end along impeller shaft 2 ' and the gap between the impeller housing 3 ' of rotation.Because the surface tension effects of water, the leakage of water is just caused in tiny gap, so the effective anti-leak of the structure of this single axle sleeve discharge opening does not reach the purpose of anti-leak.
In order to address the above problem, warning water system adopts the leakage-proof structure of O type circle sealing, as shown in Figure 2, an O type ring recess 34 ' is set respectively at the two ends of impeller housing 3 ', fill in respectively O type circle in each O type ring recess 34 ', on the impeller housing 3 ' discharge opening 33 ' need not be set like this.When warning water system is worked, impact at the press water of impeller 1 and directly blocked by the O type circle in left side, can't enter the gap between axle sleeve 4 ' and the impeller shaft 2 ', thereby reach the purpose of anti-leak.In addition, press water directly enters the ditch from drain opening 32 '.
But there is following shortcoming in this structure:
1, in order to guarantee that impeller shaft 2 ' beats littlely, rotation steadily must arrange 2 O type circles, and the O type in left side encloses the anti-leak effect, and the O type on right side encloses the effect of balance rotating impeller shaft.
2, often change easily damaged parts O type circle---axle is in rotation in working order the time for warning water system, and O type circle is subject to the frictional force effect of running shaft, is easy to wearing and tearing.
3, the requirement on machining accuracy of impeller shaft 2 ', axle sleeve 4 ' and O type ring recess is high.
The model utility content
In view of this, the purpose of this utility model is to provide a kind of and is easy to process and anti-leak rotary sleeve easy to maintenance.
The purpose of this utility model is also to provide a kind of and is easy to process and the warning water system with anti-leak rotary sleeve easy to maintenance.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of anti-leak rotary sleeve, the inwall of axle sleeve is equipped with groove, and groove is outside by the discharge opening conducting.
A kind of warning water system with anti-leak rotary sleeve, comprise impeller, impeller shaft, impeller housing and axle sleeve, the arranged outside axle sleeve of impeller housing, impeller shaft is arranged in the impeller housing, one end of impeller shaft is installed impeller, the other end passes impeller housing and axle sleeve successively, and the inwall of described axle sleeve is equipped with groove, and groove is by the described impeller housing of discharge opening conducting.
After adopting said structure, a kind of anti-leak rotary sleeve of the present utility model has following beneficial effect: direct machined grooves on axle sleeve, processing is simple, requirement on machining accuracy is not high, save cost, and without easily damaged parts O type circle, keeps in repair more convenient.
After adopting said structure, a kind of warning water system with anti-leak rotary sleeve of the present utility model has following beneficial effect: when warning water system is worked, water enters impeller housing and impacts impeller, press water small part on the impeller enters in the groove along impeller shaft and the gap between the impeller housing of rotation, is flowed to behind the discharge opening of then flowing through in the impeller housing and by the drain opening that arranges on the impeller housing to discharge.Because corresponding enough large, enough wide groove and discharge openings that be provided with respectively on axle sleeve and the impeller housing advance to the bell clapper end along axis thereby blocked the percolating water continuation that enters axle sleeve, thereby reach the effect of anti-leak.And processing is simple, requirement on machining accuracy is not high, save cost, without easily damaged parts O type circle, keeps in repair more convenient.
