Abstract
The utility model relates to an industry online flow instrument examination application apparatus, discharge standard device reducing sleeve. Is characterized in that a reducing sleeve is arranged in the verification pipeline, and the diameter of the orifice of the reducing sleeve is the same as that of the orifice of the flow meter. The utility model has the advantages that: the occupied area is small, and the multi-aperture detection technology can be realized on the effective occupied area. The construction is simple, and the effect is obvious.
Description
Technical field
The utility model relates to the online flow instrument calibrating of a kind of industry application apparatus, water flow standard apparatus reducing sleeve pipe.
Background technology
Water flow standard apparatus is used to examine and determine the fluid flow instrument, and the fluid flow instrument is widely used in the liquid flow mearuement of each factories and mines.Each flowmeter must be examined and determine before installing and using.Existing domestic industry much will satisfy the flow instrument of the calibrating of various instrument with regard to a specification of a pipeline calibrating of necessary employing with the measurement bore kind of flow instrument, and the structure floor area of this calibrating pattern needs to expend a large amount of funds very greatly again.
Summary of the invention
The purpose of this utility model provides a kind of water flow standard apparatus reducing sleeve pipe easy to operate, simple in structure, can be implemented on the caliber calibrating of the flow instrument of realizing multiple caliber, and can reduce to take up an area of with area, economizes on the use of funds.
The utility model is achieved through the following technical solutions:
Water flow standard apparatus reducing sleeve pipe is provided with the reducing sleeve pipe in the calibrating pipeline, the nozzle diameter of this reducing sleeve pipe is identical with the nozzle diameter of flow instrument.
The utility model has the advantages that: floor area is little, can effectively realize many bores detection technique on the floor area.Construction is simple, and effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of water flow standard apparatus reducing sleeve pipe.
Embodiment
See Fig. 1, install reducing sleeve pipe 2 additional in expansion bend place calibrating pipeline, the nozzle diameter of this reducing sleeve pipe is identical with the nozzle diameter of flow instrument.On a calibrating pipeline, adopt the upstream straight length 1 of reducing technique guarantee flowmeter installation, the measuring technique that downstream straight length 3 is realized many bores flow instruments.
This reducing sleeve pipe can be realized the flow instrument of nozzle diameter of the duct survey Φ 250mm of Φ 300mm, and the diameter of reducing sleeve pipe 2 is Φ 250mm.
Also can realize the flow instrument of nozzle diameter of duct survey Φ 80mm, the Φ 65mm of Φ 150mm, the diameter of reducing sleeve pipe 2 is respectively Φ 80mm, Φ 65mm.
Claims (1)
1, water flow standard apparatus reducing sleeve pipe is characterized in that, in the calibrating pipeline reducing sleeve pipe is set, and the nozzle diameter of this reducing sleeve pipe is identical with the nozzle diameter of flow instrument.
