Description
Technical Field
The utility model belongs to the technical field of water meters, and relates to an impeller box of a water meter.
Background
The impeller box of the water meter is the main part of the rotor type water meter, it is installed in the meter body of the water meter, and rotate relative to the meter body of the water meter, there are inlet openings and apopores on the impeller box, the impeller box has three kinds of effects: firstly, water enters from the water inlet hole to impact the impeller and then flows out from the water outlet hole; secondly, the impeller is protected; thirdly, the speed of rotation of the impeller can be adjusted. The rotor type water meter can be divided into a rotor type multi-flow-beam water meter and a rotor type single-flow-beam water meter according to the number of water inlets, the working principle of the rotor type multi-flow-beam water meter is basically the same as that of the rotor type single-flow-beam water meter, and a plurality of water flows impact an impeller from a water inlet of an impeller box in a tangential direction through the distribution effect of the impeller box, so that the influence of water meter installation and scaling on water meter errors can be reduced, but the impeller box of the existing water meter has the following defects: because the design of the water inlet hole and the water outlet hole on the impeller box is not reasonable enough, the water flow in the impeller box is not stable enough, and the metering is influenced.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides an impeller box of a water meter. The technical problem solved by the utility model is how to make the rectification effect of the impeller box better.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides an impeller box of water gauge, includes the box body, is provided with the apopore on the box body, its characterized in that, run through on the lateral wall of box body and seted up a plurality of inhalant canal, and inhalant canal sets up for the blade direction of slope orientation impeller, inhalant canal is rectangular form including the water inlet that is located box body lateral wall surface and the delivery port that is located box body lateral wall internal surface, delivery port.
The inlet channel of this impeller box body of water gauge sets up towards the blade direction of impeller for the slope for on the rivers that get into inlet channel from the water inlet can all strike the blade of impeller (the circumstances that partial rivers strike impeller mounted epaxial can not appear), make rivers keep balance to the axial impact force of impeller, thereby can reduce the wearing and tearing of impeller supporting part, and simultaneously, inlet channel's delivery port is rectangular form, make rivers more steady when getting into the box body from inlet channel's delivery port, thereby make the rectification effect of impeller box better.
In the impeller box of the water meter, the plurality of water inlet channels are uniformly distributed at the bottom of the side wall of the box body along the circumferential direction. A plurality of inhalant canal along circumference evenly distributed in the bottom of box body lateral wall for the rectification effect of impeller box is better.
In the impeller box of the above-mentioned water gauge, the apopore is the slope and sets up at the top of box body lateral wall, and the apopore is a plurality of, and a plurality of apopore is at the top of box body lateral wall along circumference evenly distributed. The structure can ensure that the rectifying effect of the impeller box is better.
In the impeller box of the above water meter, at least one flow guiding plane inclined towards the blade direction of the impeller is arranged on the inner wall of the water inlet channel. The guide plane can guide the water flow to impact the blades of the impeller.
In the impeller box of the water meter, the flow guide plane gradually widens from the water inlet to the water outlet. The diversion plane gradually widens from the water inlet to the water outlet, so that the diversion plane has better diversion effect.
In the impeller box of the water meter, the water inlet is elliptical.
In the impeller box of the water meter, the top surface of the box body is downwards provided with a plurality of process grooves. The process groove can prevent the inner surface of the shell from leaving processing marks due to the fact that the wall thickness of the box body is too thick, and can play a role in reducing weight.
Compared with the prior art, the impeller box of the water meter has the advantages that: the inlet channel of this impeller box body of water gauge sets up towards the blade direction of impeller for the slope for on the rivers that get into inlet channel from the water inlet can all strike the blade of impeller (the circumstances that partial rivers strike impeller mounted epaxial can not appear), make rivers keep balance to the axial impact force of impeller, thereby can reduce the wearing and tearing of impeller supporting part, and simultaneously, inlet channel's delivery port is rectangular form, make rivers more steady when getting into the box body from inlet channel's delivery port, thereby make the rectification effect of impeller box better.
