Abstract
The utility model discloses a kind of fluid rectifier applied to DN15 Ultrasonic water meters.The utility model is used for the Ultrasonic water meter rectification that pipeline nominal diameter is 15MM, and it is cylinder column-shaped sector rectifier, and sector portion is between two concentric cylinders, and sector portion hollow out, remainder is entity, and current pass through from fan-shaped hollow out position.The utility model is arranged on Ultrasonic water meter inlet pipeline inwall, can be effectively reduced vortex flow influence, effectively ensures that fluid distrbution is consistent with ideally fluid distrbution under the working condition of Ultrasonic water meter.
Description
Technical field
The utility model belongs to fluid flow detection technique field, and it is whole to be related to a kind of fluid applied to DN15 Ultrasonic water meters
Flow device.
Background technology
In flow instrument calibration check, the degree of accuracy of the rate of flow of fluid distribution for velocity-type instrument can with measurement
Play the role of by property very important, therefore in actual applications, typically there is certain requirement to flow instrument mounting condition.State
Suggest that water meter should ensure that upstream straight length should have no less than 5DN's no less than 10DN, downstream in family vertification regulation JJG162-2009
Flow development length（DN is internal diameter of the pipeline）.But in actual applications, due to being restricted by site condition etc., it is sometimes difficult to reach
Installation requirement.It is to install fluid rectifier additional in water meter upstream end to solve one of effective means of this problem, to eliminate fluid
Upstream unsteady state, shorten necessary flow development length.
The content of the invention
For the problem present on, the utility model proposes a kind of fluid rectifier applied to DN15 Ultrasonic water meters.
The utility model technical solution adopted for solving the technical problem is：
The utility model is used for the Ultrasonic water meter rectification that pipeline nominal diameter is 15MM, and it is cylinder column-shaped sector rectification
Device, sector portion is between two concentric cylinders, sector portion hollow out, and remainder is entity, and current are from fan-shaped hollow out
Pass through in position.
Furtherly, described sector portion is symmetrical around the center of circle, shares eight.
The beneficial effects of the utility model are：Simple in construction, manufacture is easy.The utility model enters installed in Ultrasonic water meter
On mouth inner-walls of duct, vortex flow influence can be effectively reduced, effectively ensures fluid point under the working condition of Ultrasonic water meter
Cloth is consistent with ideally fluid distrbution.Flow profile sensitivity grade is by the minimum straight length requirement of upstream and downstream simultaneously
U10D5 is changed into effectively eliminating the restriction of fabricating yard condition without desired U0D0 to upstream and downstream straight length.
Brief description of the drawings
Fig. 1 is the schematic diagram of fluid rectifier.
Embodiment
The utility model technology contents are further illustrated below in conjunction with accompanying drawing.This rectifier is mainly used in stabilization and enters inbound traffics
The state of the fluid of instrument, it is allowed to meet preferable flow velocity during flow instrument design, meets the requirement of its normal work.This practicality
New is cylinder column-shaped sector rectifier, for installed in Ultrasonic water meter inlet pipeline inwall, suitable for pipeline nominal diameter
For 15MM Ultrasonic water meter.
Embodiment：Reference picture 1, the utility model are cylinder column-shaped sector rectifier, are incited somebody to action by an inner circle and one are cylindrical
One disc is divided into 8 small sectors, and fan shape is hollow, and remaining is entity.Current by wherein fan-shaped hollow part by,
For the Ultrasonic water meter that pipeline nominal diameter is 15MM.
To sum up, the utility model is super to reduce installation in the case of ensureing that Ultrasonic water meter accuracy, crushing are standard compliant
The length requirement of required straight length during sound water meter.
