Abstract
The utility model discloses an impeller box which comprises a box body, wherein a tip is fixed at the bottom in the box body; a water inlet for communicating a water inlet cavity of a meter housing with a cavity of the box body is formed in the lower part of the circumferential wall of the box body; a radial convex ring arranged on a filter net cover or a baffle of the meter housing is arranged in the middle outside the circumferential wall of the box body; a water outlet groove for communicating a water outlet cavity of the meter housing with the cavity of the box body is formed in the upper part of the circumferential wall of the box body; a plurality of circumferentially and uniformly distributed flow holes for communicating the water inlet cavity of the meter housing with the cavity of the box body are formed in the bottom of the box body. The impeller box has the advantages that the circumferentially and uniformly distributed flow holes for communicating the water inlet cavity of the meter housing with the cavity of the box body are formed in the bottom of the box body, and an upward push force is applied to an impeller through the water stream of the flow holes, so that the friction force between the impeller and the tip is reduced, the driving force of a water meter is reduced, and the sensitivity of the water meter is improved.
Description
Technical field
The utility model relates to a kind of water meter parts, especially relates to a kind of impeller box.
Background technology
Water meter is a kind of conventional water metering apparatus.Water meter is generally rotary wind type, need to impeller box be set in the outside of impeller, to reduce hydraulic pressure, impacts the damage to impeller.Existing impeller box, comprise box body, box body is provided with for holding the box body cavity of impeller, box body bottom is fixed with top, box side wall bottom is provided with the inlet opening that is communicated with watchcase water inlet cavity and box body cavity, box side wall middle part is provided with for being shelved on the block reinforcement on filtering screen or watchcase baffle plate, and box side wall top is provided with the apopore that is communicated with box body cavity and watchcase water outlet cavity.Impeller is located in box body cavity, impeller due to self gravitation when rotating can with top formation friction, cause part power waste, make the sensitivity of water meter, in water-deficient area, some people utilizes this specific character to steal water, make waters corporation's revenue losses, and the income that is in want of funds cannot inject capital into waters corporation to carry out renewal of the equipment, improvement, cause water shortage problem to solve, form vicious cycle, urgently improve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of impeller box that improves water meter sensitivity.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of impeller box, comprise box body, box body inner bottom part is fixed with top, box body circumferential wall bottom is provided with the inlet opening that is communicated with watchcase water inlet cavity and box body cavity, the outer middle part of box body perisporium is provided with for being shelved on the radially flange collar on filtering screen or watchcase baffle plate, and box body circumferential wall top is provided with the effluent trough that is communicated with box body cavity and watchcase water outlet cavity; Box body bottom is provided with a plurality of connection watchcase water inlet cavitys that are circularly and evenly distributed and the hole of shoving of box body cavity.
As preferably, described in shove Kong Weisan.
As preferably, described in the hole of shoving be oblique setting, form the angle of 65 ° ~ 75 ° with box body bottom interior surface.
Compared with prior art, the utility model has the advantage of and in box body bottom, be provided with a plurality of connection watchcase water inlet cavitys that are circularly and evenly distributed and the hole of shoving of box body cavity, current by the hole of shoving form thrust upwards to impeller, thereby reduce impeller and top friction force, the sensitivity that has improved water meter.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model.
Fig. 2 is upward view of the present utility model.
Fig. 3 is front elevation of the present utility model.
Shown in figure: 1, box body, 11, box body cavity, 12, inlet opening, 13, flange collar radially, 14, effluent trough, 15, the hole of shoving, 16, arc flange, 17, top gib screw, 18, rectifying block, 19, screw hole, 2, top.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
This preferred embodiment is a kind of impeller box as shown in Figure 1 to Figure 3, comprise box body 1, box body 1 inner bottom part is fixed with top 2 by top gib screw 17, box body 1 circumferential wall bottom is provided with the inlet opening 12 that is communicated with watchcase water inlet cavity and box body cavity 11, the outer middle part of box body 1 perisporium is provided with for being shelved on the block reinforcement 13 on filtering screen or watchcase baffle plate, and box body 1 circumferential wall top is provided with the effluent trough 14 that is communicated with box body cavity 11 and watchcase water outlet cavity; Box body 1 bottom is provided with a plurality of connection watchcase water inlet cavitys that are circularly and evenly distributed and the hole 15 of shoving of box body cavity 11 bottoms.
In the present embodiment, the hole 15 of shoving is three; Preferably, the oblique setting in hole 15 of shoving, forms the angle of 65 ° ~ 75 ° with box body bottom interior surface, the power of the current that flow into by the hole 15 of shoving, between reduction impeller and top 2, in friction force, can give impeller part expulsive force, make water meter sensitiveer.Quantity and the pore size thereof in hole 15 of shoving is relevant to the weight of impeller with oblique angle, and the current that flow into from the hole 15 of shoving are less than the weight of impeller to the thrust of impeller.
