Description

Ultrasonic flow instrument shell

Technical Field

The utility model belongs to the technical field of flow instrument and specifically relates to an ultrasonic flow instrument meter shell is related to.

Background

All ultrasonic flow meter housings on the existing market are manufactured in three ways: firstly, casting, secondly forging, thirdly plastic injection molding, and the casting mode is high pollution and high energy consumption, and because the components are difficult to control in the casting process, the components of the material are uneven, the requirements of strength, corrosion resistance and the like cannot be met, and the casting sand holes are easy to cause leakage. Leading to high cost, no environmental protection and no economy; the forging needs to be heated to thousands of degrees, the energy consumption is high, and meanwhile, as the complex cavity cannot be processed, the material utilization rate is only 30-50%, and the processing workload is large; the plastic material has low strength and is easy to deform, the metering precision is influenced, and the service life is uncontrollable. Therefore, it is necessary to design a housing of an ultrasonic flow meter, which has high structural strength, simple processing, low processing cost, easy mass production, less waste generated in the processing process and less pollution.

Chinese patent application publication No. CN2757295, published as 2006, 02/08, entitled "flow meter case with metal connecting piece and plastic case communicated and injection molded as one body", discloses a flow meter case comprising a case 1 made of plastic material and metal connecting pipe pieces 2 arranged at both sides of the case 1; one end of the metal connecting pipe fitting 2 is buried in the solid tissue of the shell 1, the other end of the metal connecting pipe fitting 2 is provided with an external thread 2-1, the outer circumferential end face of the metal connecting pipe fitting 2 is provided with an injection molding through hole 2-3 and an injection molding groove 2-5, the inner pipe wall of the external thread 2-1 section of the metal connecting pipe fitting 2 is provided with an injection molding hole 2-4, and the shell 1 and the metal connecting pipe fitting 2 are communicated with each other and are molded into a whole. The instrument housing of this patent still suffers from the problems described above.

Disclosure of Invention

The utility model discloses an overcome prior art well flow meter housing and make high pollution, high energy consumption, with high costs not enough, provide an ultrasonic flow meter housing, structural strength is high, and processing is convenient, realizes big batch, fast production, and does not produce advantages such as extra waste material pollution.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an ultrasonic flow appearance meter shell, includes pipy watchcase body, and watchcase body both ends are bent towards the center and are formed the terminal surface supporting part, are equipped with the mounting hole on the watchcase body lateral wall, are equipped with the sensor mount on the mounting hole, and the sensor mount is fixed with the watchcase body.

In the technical scheme, the meter shell is made of the existing metal pipe through direct mechanical extrusion, cutting and other modes, so that the cost is greatly reduced, and mass and rapid production can be realized. The end face supporting part can increase the strength of two ends of the watchcase body, and is convenient to process and free from waste and extra pollution due to the fact that the end face supporting part is bent from the two ends of the watchcase body to the center.

Preferably, the inner side wall of the watchcase body is provided with a fixing ring. The fixing ring can be used for fixing and installing parts in the watchcase body.

Preferably, the number of the mounting holes is 2, and the fixing ring is mounted between the 2 mounting holes. The structure is convenient for fixing parts

Preferably, the number of the fixing rings is 2, and fixing threaded holes are formed among the 2 fixing rings. The structure forms three point support to the spare part in the pair shell body, and fixed screw hole is located and fixes more reliably between 2 solid fixed rings.

Preferably, the fixing ring is formed by inwardly recessing a side wall of the case body. The fixing ring is simple in structure processing, low in processing cost and stable in structure. The recessed retaining ring may also increase the strain resistance of the case body.

Preferably, the sensor fixing frame and the watchcase body are fixed through welding or threads, or are tightly matched or adhered. The connection mode that sensor mount and watchcase body adopted can guarantee that both fixed knot construct stably can.

Preferably, the side wall of the watchcase body close to the two ends is provided with an external thread. The structure is convenient for connecting the watchcase body with other structures

Preferably, the raw material of the watchcase body is a metal pipe. The metal pipe can be common metal pipes such as a steel pipe or a copper pipe, and is convenient to obtain, low in raw material cost and easy to process.

The utility model has the advantages that: (1) the processing is simple, the processing cost is low, and mass production is easy to realize; (2) the fixing structure is stable, and parts are fixed reliably; (3) the raw materials are easy to obtain, and the cost is low; (4) the waste generated in the processing process is less and the pollution is less.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: watchcase body 1, supporting part 1.1, mounting hole 1.2, solid fixed ring 1.3, external screw thread 1.4, fixed screw hole 1.5, sensor mount 2.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an ultrasonic flow meter case comprises a tubular case body 1, wherein the case body 1 is made of a metal pipe; the two ends of the watchcase body 1 are bent towards the center to form end face supporting parts 1.1, the side wall, close to the two ends, of the watchcase body 1 is provided with external threads 1.4, the side wall of the watchcase body 1 is provided with 2 mounting holes 1.2, the mounting holes 1.2 are provided with sensor fixing frames 2, and the sensor fixing frames 2 are welded and fixed with the watchcase body 1.
