An ultrasonic water meter housing that facilitates welding positioning and flow guidance

Abstract

This invention provides an ultrasonic water meter housing that facilitates welding positioning and flow guidance. The housing includes a main body with several mounting holes. A transducer mounting base is installed within each mounting hole. Several positioning guide plates are provided on the inner wall of the main body. A positioning groove is formed at the bottom of the transducer mounting base, and the positioning guide plates are embedded within the positioning groove. This invention uses positioning guide plates on the inner wall of the main body and positioning grooves at the bottom of the transducer mounting base to match the positioning guide plates. On one hand, the cooperation between the positioning guide plates and the positioning grooves positions the transducer mounting base, determining its installation depth and preventing welding displacement. On the other hand, the positioning guide plates also guide the water flow within the main body, making it more conducive to laminar flow and thus improving measurement accuracy.

Description

Technical Field

[0001] The utility model relates to an ultrasonic water meter housing, in particular to an ultrasonic water meter housing which is convenient for welding positioning and guiding flow. Background Art

[0002] With the rapid development of ultrasonic flow detection technology, compared with traditional mechanical water meters, ultrasonic water meters, which have the characteristics of non-contact, no pressure loss, high accuracy, low cost, simple structure, wide measurement range, etc., have been increasingly widely used in recent years. An ultrasonic water meter is a new type of fully electronic water meter, which generally includes an electronic meter head and a measurement pipeline. At least a set of opposite ultrasonic transducers are arranged in the measurement pipeline to detect the time difference generated when the ultrasonic beam propagates in the water in the forward and reverse directions. A processor is arranged in the electronic meter head to analyze and process the information collected by the transducers to obtain the water flow velocity and thus calculate the flow rate.

[0003] Traditional water meters are mostly made of iron or copper and are prone to rust after long-term use, which causes harm to human health. Some existing ultrasonic water meters use stainless steel for the measurement pipeline, which does not worry about the problem of rust and can work under high-temperature fluids. However, most current stainless steel ultrasonic water meters are manufactured by stamping + welding processes, and most components are round tubes. Therefore, there are problems such as inaccurate positioning and displacement during welding of the transducer mounting seat, resulting in inaccurate alignment of the installed transducers, affecting the measurement of the water meter. At the same time, the transducer mounting seat protrudes from the inner wall of the measurement pipeline, which easily causes water flow disorder and further affects the measurement accuracy.

[0004] (I) Technical Problems to be Solved

[0005] The purpose of the utility model is to provide an ultrasonic water meter housing which is convenient for welding positioning and guiding flow, and has the functions of convenient welding positioning and guiding flow. To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] (II) Technical Solutions

[0007] An ultrasonic water meter housing which is convenient for welding positioning and guiding flow includes a housing main body. A plurality of mounting holes are opened on the housing main body, and transducer mounting seats are arranged in the mounting holes. A plurality of positioning and guiding flow vanes are arranged on the inner wall of the housing main body. A positioning groove is opened at the bottom of the transducer mounting seat, and the positioning and guiding flow vanes are embedded in the positioning groove.

[0008] Further, the positioning and guiding flow vanes are welded and fixed on the inner wall of the housing main body.

[0009] Further, the positioning and guiding flow vanes are in the shape of "冖", and its two ends respectively extend obliquely outwards into one of the mounting holes.

[0010] Furthermore, the positioning guide plate is parallel to the axis of the main body of the watch case.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, a positioning guide plate is set on the inner wall of the main body of the watch case, and a positioning groove adapted to the positioning guide plate is set at the bottom of the transducer mounting base. On the one hand, the cooperation between the positioning guide plate and the positioning groove enables the transducer mounting base to be positioned, that is, to determine its installation depth and prevent welding displacement. On the other hand, the positioning guide plate can also guide the water flow in the main body of the watch case, making it more conducive to forming a laminar flow state, thereby improving the measurement accuracy.
