Description

Technical Field

[0001] This utility model relates to the field of fixed structure technology, specifically a fixed structure. Background Technology

[0002] A flow meter is an instrument used to measure the flow rate (volume or mass flowing per unit time) of fluids (liquids, gases, steam, etc.) in pipes or open channels. It plays a crucial role in many fields such as industrial production, energy management, and environmental monitoring. Flow meters measure flow based on different physical principles: Differential pressure principle: A throttling device (such as an orifice plate or nozzle) is installed in the fluid pipeline. When the fluid flows through the throttling device, a pressure difference is generated. This pressure difference is related to the fluid flow rate, and the flow rate can be calculated by measuring the pressure difference. Electromagnetic induction principle: Applicable to conductive liquids. When a conductive liquid flows in a magnetic field, an induced electromotive force is generated perpendicular to the flow direction and the direction of the magnetic field. The magnitude of the induced electromotive force is proportional to the fluid velocity. The flow rate can be calculated; Ultrasonic principle: Utilizing the characteristic that ultrasonic waves propagate at different speeds in the flow and against the flow in a fluid, the fluid velocity is calculated by measuring the time difference of ultrasonic wave propagation in the flow and against the flow, thereby obtaining the flow rate; Turbine principle: Fluid impacts turbine blades, causing the turbine to rotate. The turbine speed is proportional to the fluid velocity, and the flow rate can be determined by measuring the turbine speed; Currently, traditional connection methods are prone to poor sealing performance during long-term use due to the relatively simple design of the sealing structure. Inadequate sealing can lead to fluid leakage. In the transportation of some flammable, explosive, toxic, and harmful fluid media, leakage may also cause safety accidents, threatening the lives of personnel and the normal operation of equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6This utility model provides a technical solution: a fixed structure, including: a connecting pipe 1, a flow meter 3, a top support frame 5, a protective frame 6, a transparent window 7, a top fixing box 12, a connecting side pipe 18, and an outer sealing pipe 21; the connecting side pipe 18 is symmetrically welded and fixed to both ends of the flow meter 3; the outer sealing pipe 21 is fixed to the outside of the connecting side pipe 18, and a sealing groove 19 is opened on the inner side of the outer sealing pipe 21; the connecting pipe 1 is installed on the inner side of the sealing groove 19, and the inner side of the connecting pipe 1 cooperates with the connecting side pipe 18; the top support frame 5 is fixed to the top of the flow meter 3; the top fixing box 12 is fixed to the top of the top support frame 5, and a mounting top plate 17 is fixed to the top of the top support frame 5; the protective frame 6 is placed above the top support frame 5, and a side mounting frame 9 is symmetrically welded and fixed to the outside of the protective frame 6, and both the top fixing box 12 and the mounting top plate 17 cooperate with the side mounting frame 9; the transparent window 7 is fixed inside the protective frame 6.

[0028] It should be noted that, in this embodiment, when connecting the connecting pipe 1 and the flow meter 3, the connecting pipe 1 mates with the inner sealing groove 19 on the inner side of the outer sealing pipe 21, and the inner side of the connecting pipe 1 mates with the outer side of the connecting side pipe 18. The side sealing ring 2 at one end of the connecting pipe 1 mates with the inner annular sealing groove 20 opened inside the inner sealing groove 19, thus sealing the connection between the connecting pipe 1, the connecting side pipe 18, the outer sealing pipe 21, and the flow meter 3.

[0035] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, a fixed through-hole plate 4 is installed inside the protective frame 6 by bolts.

[0036] It should be noted that in this embodiment, the fixed through-hole plate 4 facilitates the wiring of the flow meter 3 inside the protective frame 6.
