A flowmeter for cleaning the impeller

Abstract

The invention discloses a flowmeter which is convenient for cleaning the impeller, which comprises a housing and a magnetic detection element. The front of the housing is fixedly welded with a take-out opening, and the inner wall of the take-out opening is evenly welded with a limiting ring. A sealing groove is formed between the bit rings, a sealing ring is inlaid inside the sealing groove, a screw cover is set on the outer side of the outlet, a rotating shaft is inserted inside the outer casing, and an impeller is fixedly installed on the outer side of the rotating shaft. A connecting shaft is inlaid in the middle position of the back of the housing, and a magnetic detection element is fixedly installed on the back of the connecting shaft, and access pipes are respectively fixed at the left and right ends of the housing. In the present invention, threaded connection is provided between the screw cap and the outlet, so that the screw cap and the outlet can be easily separated and opened; at the same time, the connection between the rotating shaft and the connecting shaft is connected by a bolt, so that the rotating shaft is easy to remove and effectively prevents foreign matter from being entangled in the The impeller is not easy to clean, resulting in the flowmeter being scrapped.

Description

technical field [0001] The invention relates to the technical field of flowmeter equipment, in particular to a flowmeter which is convenient for cleaning an impeller. Background technique [0002] A flowmeter is an instrument used to measure the flow of fluid in a pipeline or an open channel. Because the working principle of the flowmeter is different, it can be divided into a differential pressure flowmeter, an impeller flowmeter, a throttling flowmeter, etc., because the impeller The structure of the type flowmeter is simple, the production cost is low, and it is widely used in the flow measurement of water and gas. [0003] The working principle of the impeller flowmeter is to place the impeller in the fluid to be measured and rotate under the impact of the fluid flow. The speed of the impeller rotation reflects the flow rate. Most of the existing impeller flowmeters are fixed and installed inside the device. , because the whole device is in a sealed state, the impeller ...

Problems solved by technology

[0005] Purpose of the invention: The purpose of the invention is to provide a flowmeter that is convenient for cleaning the impeller, so as to solve the problem that the current impeller flowmeter proposed in the above background technology is installed with a fixed structure, which makes it inconvenient if the impeller is entangled by foreign matter. Cleaning, and the internal sealing of the connection of the flowmeter is not tight enough, resulting in the risk of fluid leakage
