Flow meter capable of conveniently cleaning impeller

Abstract

The invention discloses a flow meter capable of conveniently cleaning an impeller. The flow meter comprises a shell and a magnetic detection element, a taking-out opening is fixedly welded to the front face of the shell. Limiting rings are evenly welded to the inner wall of the taking-out opening. A sealing groove is formed between the taking-out opening and the limiting ring; a sealing ring is embedded in the sealing groove; the outer side of the taking-out opening is sleeved with a screw cap, a rotating shaft is inserted into the shell, an impeller is fixedly installed on the outer side of the rotating shaft, a connecting shaft is embedded in the middle of the back face of the shell, a magnetic detection element is fixedly installed on the back face of the connecting shaft, and access pipelines are fixed to the left end and the right end of the shell respectively. The screw cap and the taking-out opening are in threaded connection, so that the screw cap and the taking-out opening areconvenient to separate and open; meanwhile, the rotating shaft and the connecting shaft are connected through the plug pin, so that the rotating shaft is convenient to take down, and the flowmeter iseffectively prevented from being scrapped due to the fact that foreign matter is wound around the impeller and inconvenient to clean.

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 ...

AI Technical Summary

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
