Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a Y-type filter. Background Technology

[0002] Y-type filters are an indispensable filtration device in pipeline systems that transport media. They are typically installed at the inlet of pressure reducing valves, relief valves, level control valves, or other equipment to remove impurities from the media, protecting the valves and equipment. Y-type filters are characterized by their advanced structure, low resistance, and convenient drainage. However, during filtration, impurities in the water flow can adhere to the filter cartridge, easily clogging it and affecting its filtration function.

[0003] To address this problem, this utility model was developed. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a Y-type filter with a simple structure and anti-clogging ability.

The valve body is provided with a sealing cover to seal the filter channel. A filter cylinder is provided on the sealing cover. The filter cylinder is located in the filter channel and filters the water flowing into the outlet channel. A rotating rod is rotatably provided on the sealing cover and the rotating rod is located inside the filter cylinder. A brush is provided on the rotating rod through a telescopic device. When the telescopic rod is extended, the brush resists the inner wall of the filter cylinder. The sealing cover is also provided with a sewage discharge device for discharging the brushed impurities.

[0006] A further improvement is that the telescopic device is a telescopic rod, which is mounted on a rotating rod, and the extension of the telescopic rod is connected to the brush via a connecting device.

[0008] A further improvement is that the anti-detachment device includes an anti-detachment block, an anti-detachment channel is provided on the connecting rod, a first channel is provided on the extending rod, the anti-detachment block is located in the first channel, a pushing device is provided in the first channel to push the anti-detachment block into the anti-detachment channel, and a return device is provided on the extending rod to return the anti-detachment block to its original position.

[0009] A further improvement is that the pushing device is a spring, one end of which is connected to the anti-detachment block, and the other end of which is connected to the inner wall of the first channel.

[0010] A further improvement is that the return device includes a rotating sleeve, which is mounted on the extension rod. A magnet is provided inside the rotating sleeve on the same straight line as the first channel, and the anti-detachment block has a magnetic force that attracts the magnet.

[0011] A further improvement is that the sewage discharge device is a sewage discharge plug, the sealing cover has a sewage discharge channel, and the sewage discharge plug is threadedly connected and inserted into the sewage discharge channel.

[0016] Figure 2 This is a schematic diagram of the connecting device structure according to an embodiment of the present utility model. Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-2The present invention discloses a Y-type filter, comprising a valve body 1, an inlet channel 2 and an outlet channel 3 formed on the valve body 1, and a filter channel formed between the inlet channel 2 and the outlet channel 3. The valve body 1 is provided with a sealing cover 4 to seal the filter channel. The sealing cover 4 is provided with a filter cylinder 5. The filter cylinder 5 is located in the filter channel and filters the water flowing into the outlet channel 3. The sealing cover 4 is rotatably provided with a rotating rod 6, which is located inside the filter cylinder 5. The rotating rod 6 is provided with a brush 7 via a telescopic rod 8. The telescopic rod 8 is provided on the rotating rod 6. The extension of the telescopic rod 8 is connected to the brush 7 via a connecting device. When the telescopic rod 8 is extended, the brush 7 resists the inner wall of the filter cylinder 5. The sealing cover 4 is also provided with a drain plug 10 for discharging the cleaned impurities. The sealing cover 4 has a drain channel. The drain plug 10 is threadedly connected and passes through the drain channel. The sealing cover 4 is provided with a drive motor to drive the rotating rod 6 to rotate.

[0019] Specifically, the connecting device includes a connecting rod 11, an anti-detachment block 13, and a rotating sleeve 12. One end of the connecting rod 11 is mounted on the brush 7. A connecting channel is provided on the extension rod, and the other end of the connecting rod 11 passes through the connecting channel. An anti-detachment channel is provided on the connecting rod 11. A first channel 15 is provided on the extension rod, and the anti-detachment block 13 is located in the first channel 15. A pushing device is provided in the first channel 15 to push the anti-detachment block 13 into the anti-detachment channel. A spring 14 is provided on the extension rod to return the anti-detachment block 13 to its original position. One end of the spring 14 is connected to the anti-detachment block 13, and the other end of the spring 14 is connected to the inner wall of the first channel 15. The rotating sleeve 12 is mounted on the extension rod, and a magnet (not shown in the figure) is provided in the rotating sleeve 12 on the same straight line as the first channel 15. The anti-detachment block 13 has a magnetic force that attracts the magnet.

[0020] In order to better remove impurities from the filter cartridge 5, the rotating rod 6 is provided with a fixed rod, and the fixed rod is provided with an ultrasonic vibrating rod 9.

[0021] Working principle:

[0022] In use, when water enters through the inlet channel 2, flows through the filter cylinder 5, and then flows out through the outlet channel 3, the filter cylinder 5 filters impurities, which adhere to the filter screen. Then, the drive motor operates, causing the rotating rod 6 to rotate. The ultrasonic vibrator 9 then operates, vibrating the inner wall of the filter cylinder 5, causing the impurities attached to the surface to be dislodged. The telescopic rod 8 then operates intermittently, causing the brush 7 to intermittently resist the inner wall of the filter cylinder 5, thus cleaning the inner wall. Finally, the drain plug 10 is opened to remove the impurities. The ultrasonic vibrator 9 effectively shakes off and cleans the impurities. The intermittent brushing of the brush 7 effectively cleans the filter cylinder 5, and the intermittent resistance prevents the brush 7 from being easily damaged due to prolonged contact with the filter cylinder 5, thus extending the service life of the brush 7. When replacing the brush 7, rotate the rotating sleeve 12 so that the magnet and the anti-detachment block 13 are on the same straight line. At this time, the magnet and the anti-detachment block 13 are attracted to each other, causing the anti-detachment block 13 to slide out of the anti-detachment channel. This allows the connecting rod 11 to be removed directly. Then, insert the connecting rod 11 of the new brush 7 into the connecting channel and rotate the anti-detachment sleeve to make the magnet and the anti-detachment block 13 misaligned. Then, the anti-detachment block 13 automatically slides into the anti-detachment channel under the action of the spring 14 and engages, thus completing the installation. It is simple and convenient.
