DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-3This patent provides a technical solution: a control valve filter device capable of filtering fluid impurities, comprising a control valve 1 and a filter pipe 2, wherein one end of the control valve 1 is connected to an external indoor pipe, and the other end of the control valve 1 is installed by one end of the filter pipe 2, and the other end of the filter pipe 2 is connected to an external heating pipe;

[0022] The control valve 1 used in this article is a ball valve. By rotating the upper wheel to drive the internal ball to rotate, the on-off between the pipes on both sides is controlled. The filter pipe 2 needs to be connected to the external heating pipe so that the water flow in the heating pipe is filtered before flowing into the indoor pipe to avoid blockage of the indoor pipe and affect the indoor heating effect.

[0023] A filter screen plate 3 is installed in the filter pipe 2, and the filter screen plate 3 is in an inclined state. A through hole 4 is opened on the upper wall of the filter pipe 2, and a push rod 5 is inserted and installed in the through hole 4. A scraper 6 is installed at one end of the push rod 5 located in the inner cavity of the filter pipe 2, and the scraper 6 is in contact with the side wall of the filter screen plate 3;

[0024] When the push rod 6 is pushed, the push rod 5 drives the scraper 6 to move downward, so that it scrapes off the impurities attached to the filter screen 3 to avoid affecting the water intake. Then the scraper 6 continues to move downward, pressing the baffle 10 above the collection tube 7 downward, so that it discharges the impurities into the collection tube 7.

[0025] A collecting cylinder 7 is inserted into the lower wall of the filtering pipe 2, a net cylinder 8 is rotatably installed on the lower wall of the collecting cylinder 7, and a connecting pipe 9 is installed on the outer side of the net cylinder 8;

[0026] Since water will also flow into the collecting tube 7 during cleaning, the device sets a net tube 8 below the collecting tube 7. By rotating the net tube 8, the impurities inside can be separated from the water, and then the separated water is discharged into the external indoor pipeline through the action of the water pump 12.

[0027] Specifically, a baffle 10 is rotatably mounted on the inner wall of the collecting tube 7 . The baffle 10 is made of rubber. One end of a spring 11 is mounted on the lower wall of the baffle 10 . The other end of the spring 11 is mounted on the inner wall of the collecting tube 7 .

[0028] Specifically, it also includes a water pump 12, the water pump 12 is electrically connected to an external power supply, one end of a delivery pipe 13 is installed at the output end of the water pump 12, the other end of the delivery pipe 13 is connected to an external indoor pipeline, a one-way valve 14 is installed at one end of the delivery pipe 13 located inside the external indoor pipeline, and a connecting pipe 9 is sleeved on the outside of the input end of the water pump 12;

[0029] The one-way valve 14 can prevent the water flow in the indoor pipeline from flowing back into the delivery pipe 13.

[0030] Specifically, a sealing ring 15 is inserted into the through hole 4 and is sleeved on the outside of the top rod 5;

[0031] The sealing ring 15 can prevent water from overflowing from the through hole 4. In this article, a sealing structure is also provided between the collecting cylinder 7 and the net cylinder 8, so that when the net cylinder 8 rotates, no water will overflow between the two.

[0032] Specifically, a convex ring 16 is installed on the upper wall of the net cylinder 8 , and an annular sliding groove 17 is opened on the lower wall of the collecting cylinder 7 . The convex ring 16 can be inserted into the annular sliding groove 17 , and the convex ring 16 can slide in the annular sliding groove 17 .

[0033] Specifically, a positioning hole 18 is formed on the side wall of the collecting tube 7, a latch 19 is inserted into the positioning hole 18, and an annular groove 20 is formed on the side wall of the convex ring 16, and the latch 19 can be inserted into the annular groove 20;

[0034] By inserting the latch 19 into the annular groove 20, the net tube 8 can be prevented from falling off the collecting tube 7. When disassembling, the net tube 8 can be easily removed by simply pulling out the latch 19, which is very convenient.

[0035] Working principle: the filter pipe 2 is connected to the external heating pipe so that the water in the heating pipe is filtered before flowing into the pipe inside the house. After a period of filtration, the filter screen 3 needs to be cleaned. By pressing down the top rod 5, the top rod 5 will drive the scraper 6 to move downward, so that it can scrape off the impurities attached to the filter screen 3 to avoid affecting the water intake. Then the scraper 6 continues to move downward and presses down the baffle 10 above the collection tube 7, so that it discharges the impurities into the collection tube 7.

[0036] Since water will also flow into the collecting tube 7 during cleaning, the device sets a net tube 8 below the collecting tube 7. By rotating the net tube 8, the impurities inside can be separated from the water, and then the separated water is discharged into the external indoor pipeline through the action of the water pump 12.
