Description

Technical Field

[0001] The utility model relates to the technical field of float flowmeters, in particular to a float flowmeter. Background Art

[0002] A float flowmeter, also known as a rotor flowmeter, is a commonly used flow measurement instrument. It consists of a tapered circular tube with an enlarged inner diameter and a float that rises and falls within the tube in response to the flow rate of the measured medium. Float flowmeters offer advantages such as simple structure, low cost, stable operation, high reliability, and minimal throttling pressure loss. In particular, they can measure low flow rates of low Reynolds numbers. Therefore, they are widely used in liquid and gas flow measurement and automatic control systems in industries such as petroleum, chemical engineering, semiconductors, metallurgy, light chemical industry, and food hygiene. During use, impurities or sediment entrained in the liquid can easily accumulate within the flowmeter's circular tube, causing blockage, affecting the liquid flow rate, and reducing the meter's accuracy. This necessitates cleaning the flowmeter. However, cleaning existing flowmeters requires disassembling the entire tube from the pipeline, then reassembling the tube and float components, and then reinstalling the flowmeter back into the pipeline. This is difficult, time-consuming, and labor-intensive. Utility Model Content

[0003] The utility model mainly provides a float flowmeter, which solves the problem that the existing flowmeter needs to be disassembled from the pipeline as a whole when cleaning, and the round tube and float components on the flowmeter need to be disassembled and assembled again before cleaning, and then the flowmeter needs to be installed back on the pipeline after cleaning, which is difficult to operate in practice and is time-consuming and labor-intensive.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A float flowmeter comprises a tube body having a conical hollow cavity and a float assembly disposed within the tube body. The meter also includes a side sliding stop assembly, a rear cover plate, a front cover plate, and a pipe joint. A pipe connection ring for connecting to an external pipe is rotatably connected to the outer end of the pipe joint. An outer frame is rotatably connected to the outer wall of the pipe joint below the pipe connection ring. Two side sliding stop assemblies are disposed on opposite sides of the outer frames. The rear cover plate is detachably connected to the rear sides of the two outer frames, and the front cover plate is detachably connected to the front sides of the two outer frames. The ends of the tube body are threadedly connected to the pipe joints at both ends. Sealing between the pipe joint and the pipe connection ring can be achieved using shaft seals or dynamic seals. The pipe connection ring is threadedly connected to the external pipe, and the pipe connection pipe is provided with threads that mate with the external pipe. The pipe joint can be rotatably connected to the outer frame and the pipe connection ring using any existing component, such as a bearing or a rotating ring, as long as the technical principle can be achieved. During use, when the pipe body needs to be removed, first remove the front cover and the rear cover from the outer frame, stabilize the pipe body to limit it and rotate the pipe joint, so that the pipe joint is separated from the corresponding section of the pipe body, and the setting of the side sliding limit assembly can limit the outer frame; when the cleaned pipe body or the directly replaced pipe body needs to be installed, directly rotate the end of the pipe body to cooperate with the corresponding pipe joint to achieve connection and fixation. After the two ends of the pipe body are fixed, the front cover and the rear cover are detachably connected to the outer frame. The structure of the present application can be connected to the external pipe through the pipe connecting ring, and the pipe connecting ring and the pipe joint are connected in a rotating manner. When the pipe connecting ring is used to connect to the external pipe, the pipe joint will not rotate with it, so that other components can be disassembled and assembled with the external pipe without rotating, and when the pipe joint and the pipe body are rotated and disassembled, it will not affect the connection between the pipe connecting ring and the external pipe; the pipe joint can be connected to the pipe body at both ends through threads, and the connection method is simple and stable; the outer frame and the pipe joint are connected in a rotating manner, so that the outer frame will not be driven to rotate when the pipe joint is rotated to assemble and disassemble the pipe body, thereby supporting the two outer frames through the side sliding limit assembly and ensuring the integrity of the structure; at the same time, during the use of the flowmeter, since the pipe connecting ring and the pipe joint are rotatably connected, the direction of the pipe body can be adjusted by rotating the pipe joint, so that the pipe body faces the direction of the observer; the use of the front cover plate and the rear cover plate can provide a certain protective effect on the pipe body.

[0006] Furthermore, the side sliding limiter assembly includes a limiter guide rod slidably connected to the outer frame, with anti-slip tabs at each end. This structure allows the limiter guide rod to be directly inserted into the corresponding installation position on the outer frame. The anti-slip tabs then position the two pipe joints after the pipe body is removed, preventing misalignment and saving time during subsequent pipe installation and alignment, thereby ensuring efficient pipe installation.

[0007] Furthermore, the anti-slipping head is threadedly connected to the end of the position-limiting guide rod. With this structure, the anti-slipping head can be conveniently disassembled and assembled.

[0008] Furthermore, the pipe joint between the outer frame and the pipe connecting ring is provided with a first anti-slip groove, and the pipe connecting ring is provided with a second anti-slip groove. With this structure, it is convenient for the operator to rotate the pipe connecting ring and the pipe joint to avoid slipping.

[0009] Furthermore, the outer frame is provided with a protruding rod, on which a connecting cap is threadedly connected; and the rear cover plate and the front cover plate are provided with through holes that fit the protruding rod. This structure facilitates the assembly and disassembly of the rear cover plate and the front cover plate.

[0010] Beneficial effects: The structure of the present application can be connected to the external pipe through the pipe connecting ring, and the pipe connecting ring and the pipe joint are connected in a rotating manner. When the pipe connecting ring is used to connect to the external pipe, the pipe joint will not rotate with it, so that other components can be disassembled and assembled with the external pipe without rotating, and when the pipe joint and the pipe body are rotated and disassembled, the connection between the pipe connecting ring and the external pipe is not affected; the pipe joint can be connected to the pipe body at both ends through threads, and the connection method is simple and stable; the outer frame and the pipe joint are connected in a rotating manner, so that the outer frame will not be driven to rotate when the pipe joint is rotated to disassemble the pipe body, thereby supporting the two outer frames through the side sliding limit assembly and ensuring the integrity of the structure; at the same time, during the use of the flow meter, since the pipe connecting ring and the pipe joint are rotatably connected, the direction of the pipe body can be adjusted by rotating the pipe joint, so that the pipe body faces the direction of the observer.
