Abstract
The utility model belongs to accessories of fluid measurement devices and in particular relates to a water meter with a radial plug cock type adjusting device. The water meter with the radial plug cock type adjusting device is characterized in that a water guide channel is formed in the upper part of a bracket, which is positioned beside a water flow channel of an impeller; an adjusting hole is formed in the water guide channel; a rotary adjusting plug fixing hole capable of accommodating a rotary adjusting plug is formed in the vertical direction of the adjusting hole; a communicated adjusting orifice is formed in the rotary adjusting plug; and the size and the shape of the adjusting orifice are the same as those of the adjusting hole in the bracket. When the rotary adjusting plug is fixed in the rotary adjusting plug fixing hole, the adjusting orifice is communicated with the adjusting hole, the rotary adjusting plug can rotate relative to the bracket, and a circumference angle formed between two sides of the adjusting orifice is less than 90 degrees. The water meter is simple in structure and convenient to adjust, the influence on the water flow caused by the adjusting device is small, and the metering precision of the water meter is improved.
Description
Technical field
The utility model belongs to the fluidic counter accessory, especially belongs to have the radially water meter of cock-type regulating device.
Background technology
As shown in Figure 1, 2, in order to adjust the water meter speed, improve the measuring accuracy of water meter, at present a lot of water meters all adopt adjustment sheet 2 to regulate, adjustment sheet 2 all is arranged on the middle, the outside of water meter movement water stream channel water inlet usually, regulate the water yield that enters impeller 1 by the angle of adjustment sheet 2, impeller 1 is fixed on support 5.Because adjustment sheet is positioned at water meter movement water stream channel water inlet, 2 pairs of current of adjustment sheet have certain reflex, inevitably can cause interference to current, can have influence on to a certain extent the measuring accuracy of water meter.
Summary of the invention
The utility model purpose is to overcome above-mentioned shortcoming, and a kind of regulating device less on the impact of current is provided, and has improved the radially water meter of cock-type regulating device that has of accuracy of water meter.
the technical scheme that the utility model uses is a kind of radially water meter of cock-type regulating device that has, its main points are, be positioned at support impeller the water stream channel side above be provided with guiding gutter, have adjustment hole in guiding gutter, with the vertical direction of adjustment hole on have the rotation adjusting plug fixed orifice that can hold the rotation adjusting plug, the rotation adjusting plug has the adjusting mouth that communicates, the size and shape of adjusting mouth is identical with the adjustment hole on support, when the rotation adjusting plug is fixed in rotation adjusting plug fixed orifice, regulating mouth communicates with adjustment hole, the rotation adjusting plug is rotatable with respect to support, the angle of circumference that adjusting mouthful dual-side becomes is less than 90 degree.
Principle of work of the present utility model, by rotation rotate adjusting plug make regulate mouthful with adjustment hole between the area that communicates change, close from being up to, realize the adjustment to discharge, improve thereby reach the purpose that water meter is adjusted precision, because the rotation adjusting plug is positioned on the by-pass water circulation road, substantially can not cause interference to the current of the impeller of flowing through.
There are two adjustment holes to be symmetrically distributed in the both sides of impeller.On the impact by current in impeller, be conducive to improve the water meter precision by the flow in symmetrical further reduction adjustment hole.
The rotation adjusting plug is fixed in rotation adjusting plug fixed orifice by screw and pad, has well on the other end, needs only during adjustment with specific purpose tool alignment tools groove and rotates the rotation adjusting plug.
The utility model is simple in structure, and is easy to adjust, and regulating device is little on the impact of current, improved the measuring accuracy of water meter.

Embodiment
Below in conjunction with view, the utility model is described in detail, the following examples can make the professional and technical personnel more understand the utility model, but do not limit in any form the utility model.
as Fig. 3, 4, shown in 5, a kind of have a radially water meter of cock-type regulating device, be positioned at support 5 impeller 1 the water stream channel side above be provided with guiding gutter 53, have adjustment hole 51 in guiding gutter 53, with the vertical direction of adjustment hole 51 on have the rotation adjusting plug fixed orifice 52 that can hold rotation adjusting plug 3, rotation adjusting plug 3 has the adjusting mouth 31 that communicates, the size and shape of adjusting mouth 31 is identical with the adjustment hole 51 on support, when rotation adjusting plug 3 is fixed in rotation adjusting plug fixed orifice 52, regulating mouth 31 communicates with adjustment hole 51, rotation adjusting plug 3 is rotatable with respect to support, the angle of circumference that adjusting mouthful 31 dual-sides become is less than 90 degree, namely regulate mouthful 31 width and be no more than 1/4 of rotation adjusting plug outside surface girth, rotation adjusting plug 3 is fixed in rotation adjusting plug fixed orifice 52 by screw 33 and pad 34, have well 32 on the other end.During use as long as rotate rotation adjusting plug 3 with specific purpose tool alignment tools groove, make regulate mouthfuls 31 with adjustment hole 51 between the area that communicates change, close from being up to, realize the adjustment to discharge.It is same as the prior art that all the other do not state part.
