Specifically, the first flow rate control valve 41 and/or the second flow rate control valve 42 in the present embodiment are/is a gate valve, but needless to say, the first flow rate control valve 41 and/or the second flow rate control valve 42 are not limited to the gate valve, and may be a butterfly valve, a stop valve, or the like as will be apparent to those skilled in the art, and will not be described herein.

The drain pipe 40 of the present embodiment is bent toward the drain pipe 20, and an included angle formed between the drain pipe 40 and the drain pipe 20 is preferably an acute angle, and the included angle can be specifically set according to the use requirement, which is not described herein.

In the present embodiment, the strainer 30 of the present embodiment is connected end to end and formed in a cylindrical structure, and the soil discharge pipe 40 is communicated with the liquid inlet pipe 10 through both end openings of the strainer 30. That is, the medium introduced from the liquid inlet pipe 10 can directly flow to the drain pipe 40 through the openings at the two ends of the filter screen 30, and the flow between the drain pipe 40 and the liquid inlet pipe 10 is controlled by the first flow control valve 41 and/or the second flow control valve 42 on the drain pipe 40, while the medium introduced from the liquid inlet pipe 10 to the liquid outlet pipe 20 can pass through the filter screen 30 and filter the impurities contained in the medium. It should be understood that the screen 30 of the present embodiment is not limited to a cylindrical structure, and it is obvious to those skilled in the art that the screen 30 may be a flat plate structure inserted into the drain pipe 20, and the description thereof will not be provided.

Specifically, a mounting cavity is formed on a channel opening of the liquid outlet pipe 20 in communication with the liquid inlet pipe 10, and the filter screen 30 is fixedly disposed in the mounting cavity.

Further, the pipe diameter of the drain pipe 40 of the present embodiment is larger than the aperture of the through hole in the filter screen 30, so as to ensure that the sundries dropped due to the blockage of the filter screen 30 can be completely guided into the drain pipe 40.

In addition, in the present embodiment, a guide portion 102 is formed at a position where the liquid inlet pipe 10 and the liquid outlet pipe 20 are connected, and the guide portion 102 can guide the medium introduced from the liquid inlet pipe 10 to a position where the screen 30 is located.

To sum up, the utility model provides a pipe filter utilizes the structural setting of blow off pipe for this pipe filter is when using, and available opening first flow control valve, closes the second flow control valve and realizes the sediment to debris in the filter screen, closes first flow control valve again, opens the second flow control valve and realizes the debris clearance of deposiing in the blow off pipe to this realizes the clearance to the debris that the filter screen effect deposits, and then has when being convenient for this pipe filter to use, the follow-up processing of decontaminating to the filter screen; meanwhile, the pipeline filter is simple in structure and convenient to operate.
