Water flow indicator capable of electronic display

Abstract

The invention discloses a water flow indicator capable of electronic display which comprises a valve body, a first annular mounting block is arranged on the front face of the valve body, an observation window is arranged in the middle of the first mounting block, a second annular mounting block is arranged on the back face of the valve body, a water inlet pipe is arranged on one side of the valvebody, and a water outlet pipe is arranged on the other side of the valve body. The water inlet pipe and the water outlet pipe communicate with the interior of the valve body. A first connecting blockis fixedly arranged on the front face of the second mounting block, a bearing is arranged on one side face of the first connecting block, the bearing is rotatably connected with the first connecting block, and an impeller mechanism is arranged on the side face of the impeller blocking piece, the water flow speed can be seen from the observation window; by arranging the rotating speed sensor, the electronic display screen and the signal receiver, the rotating speed sensor transmits signals to the signal receiver, the signal receiver transmits the signals to the electronic display screen, and water flow numerical values are displayed on the electronic display screen.

Description

technical field [0001] The invention relates to the technical field of water flow indicators, in particular to an electronically displayed water flow indicator. Background technique [0002] The water flow indicator is a sight glass instrument valve, which is suitable for industrial production pipelines such as petroleum, chemical industry, chemical fiber, medicine, food, power plants, pumps, etc. Through the window, the turbidity of liquid, gas, steam and other media can be observed at any time and the medium can be measured. Flow speed response is one of the indispensable pipeline accessories to ensure normal production and product quality. Its connection methods include threaded type; flange type; welded type. The water flow indicator can also be used in automatic sprinkler systems. It can be installed in The main water supply pipe or the side of the horizontal bar water pipe gives an electrical signal of water flow in a small area of ​​a certain sub-area. This electrical...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems in the prior art that the water flow velocity cannot be accurately known, and when the glass window is polluted, it is inconvenient to see the water flow velocity inside the water flow indicator. Electronically displayed water flow indicator, the water flow indicator has the effect of making it easy to see the water flow velocity inside the water flow indicator
