Abstract
The utility model relates to a sensor for ultrasonic flowmeter capable of maintaining on line, in particular to a special sensor metering the liquid flow in a pipeline by utilizing an ultrasonic measurement technique, which is suitable for metering the liquid flow and heat in the pipeline. The utility model has the technical scheme that the sensor comprises a probe rod (1) and a connecting piece (2), and the probe rod and the connecting piece are connected by screw threads. The utility model changes a mode of ensuring the inserting position of the probe rod by locking assemblies in the existing technical scheme into a mode of ensuring the inserting position of the probe rod by connecting the probe rod and the connecting piece by screw threads, and only the probe rod is screwed to a locating surface when in installation. When the sensor is adopted to carry out installation and measure the flow, the installation process can be greatly simplified, the installation time is saved, the installation repeatability is improved, and the measurement accuracy of the meter is ensured. The utility model has the characteristics of reasonable structure, advanced process, convenient installation, good repeatability and the like, overcomes the disadvantages of the prior art and can be widely applied to the measurement technique of ultrasonic flowmeters and heat meters.
Description
Affiliated technical field:
But the utility model relates to a kind of on-line maintenance ultrasonic flowmeter sensor, particularly utilizes fluid flow sensor special in the ultrasonic detecting technology metering pipeline, is applicable to the metering of fluid flow, heat in the pipeline.
Background technology:
At present, but existing on-line maintenance ultrasonic flowmeter sensor general mainly constitute by probe rod, web member and latch assembly, the dependence latch assembly is locked probe rod and web member.In use there is following problem in this sensor: sensor must guarantee that in installation process it is at ducted accurate location, promptly guarantee installation dimension, be the distance of locating surface to the probe rod top, this just requires every installation primary transducer just must accurately measure the one-step installation size, set-up time is long, and the installation repeatability of sensor is difficult for guaranteeing.
The utility model content:
But the utility model purpose provides a kind of on-line maintenance ultrasonic flowmeter sensor, improves instrument property easy for installation and repeats to install accuracy, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: but the on-line maintenance ultrasonic flowmeter comprises probe rod, web member with sensor, between web member and the probe rod by being threaded.
The utility model will rely on latch assembly to guarantee the mode of probe rod insertion position in the prior art scheme, change probe rod into and rely on to be threaded with web member and guarantee the probe rod insertion position, gets final product when only need be screwed onto the locating surface place to probe rod during installation.Compare with former technical scheme, sensor does not need accurately to measure installation dimension in installation process, saves the set-up time, and the installation effectiveness height is installed good reproducibility.
Adopt the utility model to install and when detecting flow, can simplify installation process greatly, save the set-up time, improve repeatability is installed, guaranteed the instrument measurement precision.
The utlity model has rational in infrastructure, characteristics such as technology is advanced, easy for installation, good reproducibility, overcome the shortcoming of prior art, can be widely used in the measuring technique of ultrasonic flowmeter, calorimeter.
Description of drawings:
Accompanying drawing 1 is the background technology structural representation.
Accompanying drawing 2 is the utility model example structure synoptic diagram.
Among the figure: probe rod 1, web member 2, latch assembly 3, ball valve 4, locating surface 5.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, but the on-line maintenance ultrasonic flowmeter comprises probe rod 1, web member 2 with sensor, between web member and the probe rod by being threaded.Probe rod 1 passes ball valve 4 and web member 2, and locating surface 5 is at the afterbody of probe rod.The utility model will rely on latch assembly 3 to guarantee the mode of probe rod insertion position in the prior art scheme, change probe rod into and rely on to be threaded with web member and guarantee the probe rod insertion position, gets final product when only need be screwed onto locating surface 5 places to probe rod 1 during installation.Compare with former technical scheme, sensor does not need accurately to measure installation dimension in installation process, saves the set-up time, and the installation effectiveness height is installed good reproducibility
