Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary devices of metal tube float flowmeters, in particular to a metal tube float flowmeter which is easy to assemble and disassemble. Background Art
[0002] The working principle of the metal float flowmeter is to move the float upward as the flow rate changes. At a certain position, the buoyancy of the float is balanced with the weight of the float. The flowmeter is suitable for measuring the flow of small-caliber and low-flow-velocity media.
[0003] The main components of a metal float flowmeter include a vertically tapered tube that expands upward from bottom to top and a float that moves freely up and down along the axis of the tube. It also includes a dial or scale and a readout pointer for reading the flow rate. As the measured fluid flows upward through the annular gap formed by the tapered tube and the float, the flow creates a pressure differential between the upper and lower ends of the float. This pressure differential is due to the change in static pressure caused by the change in flow velocity as the fluid passes through the annular gap. According to Bernoulli's equation, as flow velocity increases, static pressure decreases. Therefore, the lower end of the float (where the flow is faster) experiences lower static pressure, while the upper end (where the flow is slower or stagnant) experiences higher static pressure. This pressure differential creates a force that causes the float to rise. As the float rises, the buoyant force on it increases because the volume of fluid displaced by the float increases. Simultaneously, the float is affected by its own weight and fluid resistance. When the buoyant force balances with the weight and fluid resistance, the float stabilizes at a certain height, which reflects the flow rate. The above is a brief description of the working principle of the metal float flowmeter.
[0004] Currently, the metal float flowmeters on the market are all integrated. If one internal part is damaged, the entire flowmeter needs to be replaced, which increases production and processing costs. The overall structure is not easy to disassemble and maintain. Therefore, it is particularly important to design a metal tube float flowmeter that is easy to disassemble and assemble to solve the above technical problems. Utility Model Content
