Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flow meters, and particularly relates to a metal tube float flow meter. Background Art
[0002] The metal tube float flow meter is mainly applicable to measuring liquids and gases, and is widely used in fields such as petroleum, chemical industry, power generation, food, pharmacy, and water treatment, etc. Since the structure of the metal tube float flow meter is a fully metal structure, it can work under relatively harsh environmental conditions.
[0003] When the metal tube float flow meter is in use, in order to ensure a stable flow state when the fluid enters its interior, it is usually necessary to additionally install a pipeline of a certain length at the inlet end of the metal tube float flow meter. The installation of pipelines in the prior art all requires additional operations during installation. If there is no pipeline corresponding to the requirements at the installation location, the installation conditions are not available, which causes inconvenience in use. At the same time, additionally installing pipelines is also relatively time-consuming. Content of the Utility Model
[0004] The purpose of the utility model is to provide a metal tube float flow meter, which does not require additional installation of pipelines during use, reduces the labor intensity of workers, and at the same time reduces the requirements for installation conditions.
[0005] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:
[0006] A metal tube float flow meter, comprising
[0007] A measuring tube main body and a display main body, the display main body is arranged on the front side of the measuring tube main body, and the display main body has a display screen for displaying the flow rate detected by the measuring tube main body;
[0008] An assembly tube, the assembly tube is fixedly and communicatively arranged at the lower end of the measuring tube main body;
[0009] Two connecting flanges, the two connecting flanges are respectively arranged at the upper end of the measuring tube main body and the lower end of the assembly tube.
[0010] As a preferred technical scheme, the diameter range of the measuring tube main body is 15 to 50 mm.
[0011] As a preferred technical scheme, the length of the assembly tube is 5 to 8 times the diameter of the measuring tube main body.
[0012] As a preferred technical scheme, the length of the assembly tube is 5 times the diameter of the measuring tube main body.
[0013] As a preferred technical scheme, a horizontal detector is arranged at the top of the display main body.
[0014] As a preferred technical solution, the display body is fixedly connected to the outer side wall of the measuring tube body through a connecting component.
[0015] The beneficial effects of the present utility model are as follows:
[0016] During use, the assembly pipe can be directly connected to the external discharge port without the need to additionally install a pipe at the inlet end of the metal tube rotameter, reducing the labor intensity of the staff and improving work efficiency. At the same time, the length of the assembly pipe matches the diameter of the measuring tube body and is five times its diameter size, ensuring a stable flow state of the liquid while also facilitating handling, storage, and installation, with convenient operation. Description of the Drawings
[0017] The present utility model can be further illustrated by the non-limiting embodiments given in the drawings.

[0019] Figure 2 is a schematic diagram of the structure from another perspective of the present utility model.
[0020] Reference numerals: measuring tube body 1, display body 2, display screen 21, horizontal detector 22, connecting component 23,, assembly pipe 3, connecting flange 4. Detailed Embodiments
[0021] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.
[0022] As Figure 1-2 shown, a metal tube rotameter of the present utility model includes
[0023] a measuring tube body 1 and a display body 2. The display body 2 is arranged on the front side of the measuring tube body 1, and the display body 2 has a display screen 21 for displaying the flow rate detected by the measuring tube body 1;
[0024] an assembly pipe 3, and the assembly pipe 3 is fixedly and communicatively arranged at the lower end of the measuring tube body 1;
[0025] two connecting flanges 4, and the two connecting flanges 4 are respectively arranged at the upper end of the measuring tube body 1 and the lower end of the assembly pipe 3.
[0026] The diameter range of the measuring tube body 1 is 15 to 50 mm; the measuring tube body 1 within this diameter range belongs to a small-diameter tube, which is convenient for handling and installation.
[0027] The length of the assembly pipe 3 is 5 to 8 times the diameter of the measuring pipe body 1; when installing the measuring pipe body 1, the assembly pipe 3 is matched with the inlet end position of the measuring pipe body 1, and the diameter dimension of the assembly pipe 3 is the same as that of the measuring pipe body 1. In order to ensure a stable flow state when the fluid enters its interior, too long or too short a length of the assembly pipe 3 will affect the flow state stability. Therefore, the length of the assembly pipe 3 is selected with different diameters according to the diameter of the measuring pipe body 1. For example, when the diameter of the measuring pipe body is 15 mm, the length selection range of the assembly pipe 3 is 75 to 120 mm, which can ensure a stable flow state when the fluid is measured. The connection form between the assembly pipe 3 and the measuring pipe body 1 is fixed by welding.
[0028] The length of the assembly pipe 3 is 5 times the diameter of the measuring pipe body 1; specifically, the length dimension of the assembly pipe 3 is 5 times the diameter of the measuring pipe body 1, which is the best use length and the best fluid flow state.
[0029] A horizontal detector 22 is provided at the top of the display body 2; when installing the metal tube float flowmeter, it is necessary to ensure vertical installation. Therefore, the installation verticality can be visually compared through the horizontal detector 22.
[0030] The display body 2 is fixedly connected to the outer side wall of the measuring pipe body 1 through a connection component 23; the connection component 23 can stably connect and fix the display body 2.
[0031] The usage method of this device is as follows:
[0032] When in use, when selecting metal tube float flowmeters of different specifications, an assembly pipe 3 is installed at the bottom of the measuring pipe body 1. During assembly, the connection flange 4 at the bottom of the assembly pipe 3 is connected to the external liquid outlet. The installation of the assembly pipe 3 enables the fluid to have a stable flow state when entering the interior of the measuring pipe body 1. The diameter of the assembly pipe 3 is the same as that of the measuring pipe body 1, and the length of the assembly pipe 3 is 5 to 8 times the length of the measuring pipe body 1. For example, when selecting a measuring pipe body 1 with a diameter dimension of 40 mm, the length range of the assembly pipe 3 can be selected from 200 to 320 mm, and 200 mm is the optimal length. In this way, there is no need for the staff to additionally install a pipeline to connect to the inlet end of the metal tube float flowmeter later, reducing the labor intensity of the staff, improving the work efficiency at the same time, and also reducing the requirements for installation conditions.
[0033] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
