Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-4, a water pump intake visual filter comprises a water pump 1, a water inlet end 2 is arranged on the water pump 1, an equal-diameter tee 3 is connected to the water inlet end 2 through a flange, a drain valve 4 is arranged on the lower portion of the equal-diameter tee 3, the equal-diameter tee 3 comprises a horizontal pipe 31, a vertical pipe 32 is vertically connected to the upper portion of the horizontal pipe 31, the horizontal pipe 31 is communicated with the vertical pipe 32, a mounting flange plate 33 is arranged on the upper portion of the vertical pipe 32, a fixed flange plate 35 is arranged above the mounting flange plate 33, a sight glass 34 is arranged between the mounting flange plate 33 and the fixed flange plate 35, and a filter screen 36 is. The medium in the water tank connected with the equal-diameter tee joint 3 enters the equal-diameter tee joint 3, is filtered by the filter screen 36 and then enters the water pump 1 from the water inlet end 2 and is discharged. The cleaning condition of the medium flowing through the equal-diameter tee joint 3 can be directly observed through the sight glass 34, so that whether the medium needs to be replaced or not can be judged.

The mounting flange 33 and the fixed flange 35 are fixedly connected through bolts and nuts.

The filter screen 36 is enclosed into a cylinder shape, the lower end of the filter screen 36 is abutted against the inner wall of the horizontal pipe 31, the lower part of the filter screen 36 is provided with a bevel cut 361, and the bevel cut 361 is positioned on one side far away from the water pump 1.
