Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the utility model discloses visual tee bend of observable flow that area is shaded, including visual tee bend casing 4, visual tee bend casing 4 includes trunk line and lateral conduit, the both ends of visual tee bend casing 4 trunk line adopt flange 5 and pipeline flange to be connected, and the flange specification is unanimous with the installation pipeline section. An observation window is arranged on the front side of the main pipeline of the visual three-way shell 4, the observation window comprises a window, first toughened glass 8 covered on the window, sealing rings are arranged on two sides of the first toughened glass 8, and the first toughened glass 8 is fixed on the visual three-way shell 4 through a flange cover 7 arranged on the outer side and a hexagonal screw 6. The flowing condition of the medium in the main pipeline can be clearly observed through the first toughened glass 8.

In order to overcome the problem that the monitoring cannot be carried out when no light source or weak light source exists, the visible three-way shell 4 is further provided with a backlight source assembly, and the backlight source assembly is arranged near the observation window or on the visible three-way shell opposite to the observation window.

The utility model adopts the mode of self-carrying backlight to monitor, has wider application range, and can effectively avoid the situation that the running state of the medium and the working state of the flowmeter can not be observed visually because of no observation window; or in the absence of a light source or a weak light source.

As a preferred embodiment of the present invention, the backlight source assembly of this embodiment is disposed on the other side of the main pipe opposite to the observation window, and is symmetrically disposed on the longitudinal center plane of the main pipe. The backlight source assembly comprises second toughened glass 9, an LED lamp panel 10, a backlight flange cover 11 and a power supply, wherein the power supply can be realized by adopting a built-in power supply or an external power supply.
