Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of nozzle flow meters, and particularly relates to a nozzle flow meter easy to disassemble and maintain. BACKGROUND

[0002] The English name of flow meter is flowmeter, which is defined by the National Committee for Scientific and Technological Terminology as an instrument for indicating the flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is an instrument for measuring the flow rate of fluid in a pipeline or open channel.

[0003] The utilization principle of the nozzle flow meter is that when the fluid flows through the nozzle in the pipeline, the flow rate will form a local contraction at the nozzle, so that the flow rate increases and the static pressure decreases, thereby generating a pressure difference before and after the throttling element. The greater the fluid flow, the greater the pressure difference, so the size of the flow can be measured according to the pressure difference.

[0004] Since the flow meter is based on the actual use environment and use requirements, the nozzle of the flow meter needs to be replaced in various forms and shapes, and during the installation process, the detection rod of the flow meter needs to be accurately set at both ends of the nozzle to ensure that the distance between the detection rod and the nozzle is the same. Therefore, when the flow meter is installed, the installation of the nozzle is more troublesome, the position of the nozzle needs to be positioned, and the speed and efficiency of the installation are low.
