Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the utility model provides a filtering ball valve, which comprises a main channel 1 and an auxiliary channel 2, wherein the auxiliary channel 2 is arranged below the main channel 1, the auxiliary channel 2 comprises a flushing channel 3 and a sewage channel 4 which is in penetrating connection with the flushing channel 3, a ball valve core 5 is arranged on the main channel 1, a layer of filter core structure 6 is arranged in the main channel 1, and the filter core structure 6 is arranged for filtering out a part of impurities.

The flushing channel 3 is provided with a drain channel valve core 7, the drain channel 4 is connected to the flushing channel 3 in a vertical mode, the flushing channel 3 is of an L-shaped structure, the L-shaped structure is arranged to enable impurities to smoothly fall down, and then the impurities are flushed away through the flow direction of a liquid medium; the filter element structure 6 and the bottom of the main channel 1 are arranged at an included angle of 70 degrees, impurities in liquid can be filtered out in a large area through such an angle, the filter element structure 6 is arranged between the flushing channel 3 and the sewage drainage channel 4, and the filter element structure 6 is arranged above the sewage drainage channel 4.

The ball valve capable of filtering is provided with a function of filtering media and discharging particles without system stopping, not only can the filter element structure 6 with different net openings be selected for independently realizing pipeline filtering, but also the filter element structure 6 with different net openings can be selected for application to a complex filtering subsystem, and the filtering effect is exerted in each level of subsystem.

Working principle:

when the valve does not open the sewage discharging function, the medium passes through the filter element structure 6 along the main channel 1, solid matters are filtered, and the net mouth of the filter element structure 6 can be selected according to the medium of the process pipeline; the drain-passage valve core 7 on the drain-passage 4 is communicated with the upstream of the filter element structure 6, and impurities in the medium are intercepted and accumulated on the upstream of the filter element structure 6 and continuously enter the drain-passage 4 and the drain-passage valve core 7.

When the valve opens the blowdown function, the blowdown channel valve core 7 is communicated with the flushing channel 3, and filtered media flush out the particulate matters in the blowdown channel valve core 7 from the pipeline system along the flushing channel 3 and the blowdown channel valve core 7.
