Description

Technical Field

[0002] The layered multi-channel ultrasonic flowmeter is generally composed of a flange, a seamless steel pipe, an ultrasonic sensor mounting seat, an ultrasonic sensor, etc. The ultrasonic sensor mounting seat is at a certain angle to the seamless steel pipe, and the mounting holes of multiple ultrasonic sensor mounting seats are parallel to each other and evenly distributed in the seamless steel pipe according to the inner diameter of the pipe. When the ultrasonic wave passes through the liquid, the liquid has a slight effect on the transmission time, and the change in the transmission time is proportional to the liquid flow rate. According to the change in time and speed, the flow value is calculated after data analysis and processing through a high-performance chip.

[0003] The existing production process is to directly open an inclined hole on the seamless steel pipe and then weld the ultrasonic sensor mounting seat. Because it is an inclined hole, it has a certain angle with the seamless steel pipe and is required to be parallel to the center plane of the seamless steel pipe. As a result, the processing equipment needs to have sufficient travel in the three axes of XYZ to meet the processing requirements when the angle is adjustable, and the corresponding concentricity of the ultrasonic sensor cannot be guaranteed.

By setting a mounting hole located on the seamless steel pipe and perpendicular to the seamless steel pipe, the mounting base is quickly installed and connected to the seamless steel pipe with the help of mounting parts corresponding to the mounting hole. The problem of excessive difficulty in opening an inclined hole on the seamless steel pipe can be solved by only changing the angle between the receiving tube and the mounting base, thereby improving the production and installation efficiency.

[0006] Preferably, both ends of the seamless steel pipe are connected with symmetrically distributed flanges, the mounting seats are located on the same horizontal line and the diagonal mounting seats are centrally symmetrically distributed.

[0007] Preferably, the mounting hole is vertically distributed with respect to the tangent line at the corresponding position on the side wall of the seamless steel pipe, and the mounting hole is a circular hole passing through the axis center line of the seamless steel pipe.

[0026] like Figure 1 , 4 As shown in Figure 5, the utility model provides a mounting base for a special-shaped multi-channel ultrasonic flowmeter, which includes a seamless steel pipe 1, symmetrically distributed flanges 112 located at both ends of the seamless steel pipe 1, and a mounting base 2 for a plurality of symmetrically distributed ultrasonic sensors located on the side wall of the seamless steel pipe 1 and penetrating the seamless steel pipe 1. The mounting base 2 includes a convex mounting piece 211 penetrating the seamless steel pipe 1, and a receiving tube 212 located on the side of the mounting piece 211 away from the seamless steel pipe 1. The seamless steel pipe 1 is provided with a mounting hole 111 corresponding to the narrower end of the mounting piece 211 and penetrating the seamless steel pipe 1. The mounting seats 2 are located on the same horizontal line and the diagonal mounting seats 2 are centrally symmetrically distributed.

[0027] In this embodiment, by setting mounting holes 111 evenly distributed on the seamless steel pipe 1 and perpendicular to the seamless steel pipe 1, the mounting seat 2 is quickly installed and connected to the seamless steel pipe 1 with the help of mounting parts 211 corresponding to the mounting holes 111. The difficulty of opening inclined holes on the seamless steel pipe 1 can be solved by simply changing the angle between the receiving tube 212 and the mounting seat 2, thereby improving the production and installation efficiency.

[0028] It should be noted that the sensors connected to the mounting seat 2 in the seamless steel pipe 1 are a corresponding group of sensors in the same horizontal direction; the horizontal line of the mounting hole 111 on the seamless steel pipe 1 passes through the axis line of the seamless steel pipe.

[0029] like Figure 2 and Figure 3 As shown, the mounting hole 111 is vertically distributed with the tangent of the corresponding position on the side wall of the seamless steel pipe 1, the mounting hole 111 is a central circular hole, a certain angle is formed between the receiving tube 212 and the mounting piece 211, the receiving tube 212 is provided with a through hole 213 penetrating the side wall of the receiving tube 212, and the end of the receiving tube 212 close to the seamless steel pipe 1 penetrates the mounting piece 211.

[0030] In this embodiment, the mounting hole 111 is a central circular hole, and the mounting member 211 can be quickly inserted into the mounting hole 111. The production of the central circular hole is simpler and easier to operate than the production of the inclined hole, and it is more cost-effective. It only needs to change the angle between the receiving tube 212 and the mounting member 211 to achieve the same effect as the inclined hole.

[0031] When in use, during installation, it is only necessary to connect the mounting seat 2 with the mounting hole 111 on the seamless steel pipe 1 by means of the mounting member 211, and by means of a certain angle between the receiving tube 212 and the mounting member 211, the characteristics of tilting and maintaining parallel propagation paths can be achieved. The utility model has a simple structure and is easy to operate.

[0032] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
