Description

Technical Field

[0001] This utility model relates to the field of gate valves, specifically a filter gate valve. Background Technology

[0002] In fluid control systems, shut-off valves are mainly used to control the flow of fluid, while filtration is often achieved through separate filters. In specific applications, such as industrial production and water treatment, fluids often contain various impurities, including metal particles, particulate matter, and suspended solids. The presence of these impurities not only affects the quality and performance of the fluid but may also damage system equipment.

[0003] Current integrated shut-off valve and filter devices have limited filtration efficiency. When filtering metal impurities, these impurities can easily clog the filter element, affecting the filtration effect. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a filter shut-off valve.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A filter shut-off valve includes a shut-off valve with a filter on its right side. The filter has a shell structure and includes a filter tube and a sleeve. The filter tube is open at the bottom, and one end of a connecting pipe 1 and one end of a connecting pipe 2 are fixedly fixed to the left and right sides of its outer wall, respectively. A flange is provided at the other end of the connecting pipe 1, which is connected to the inlet end of the shut-off valve through the flange. The sleeve is threadedly connected to the inner wall of the bottom of the filter tube, and a filter element is slidably inserted into the sleeve. The top of the filter element abuts against the inner top wall of the filter tube, and the outer wall of the filter element abuts against the ends of the connecting pipes 1 and 2 located inside the filter tube. The right side of the pipe has a magnetic rod box, and the left side wall of the magnetic rod box is fixedly connected to the connecting pipe three. The left end of the connecting pipe three and the right end of the connecting pipe two are respectively provided with flanges. The left end of the connecting pipe three and the right end of the connecting pipe two are connected by the flanges. The right side wall of the magnetic rod box is fixedly connected to the water inlet pipe. Several guide plates are fixedly connected to the front and rear inner walls of the magnetic rod box. Two guide plates are arranged in a group, and there is a gap between the two guide plates in each group. The four groups of guide plates are arranged in a rectangular shape. The magnetic rod is located between the front and rear groups of guide plates. The magnetic rod extends forward and backward and is stacked up and down. The magnetic rod slides with the guide plate. The top of the magnetic rod box is fitted with a box cover.

[0007] Connecting plate one is fixedly connected to the top center of the front and rear side walls of the magnetic rod box, and connecting plate two is fixedly connected to the bottom center of the front and rear side walls of the box cover. Locking studs pass through the top of connecting plate two, and the locking studs are slidably connected to connecting plate two and threadedly connected to connecting plate one.

[0008] The beneficial effects of this utility model are:

[0009] This invention effectively removes metal and other impurities from water through dual filtration of magnetic rods and filter cartridges, ensuring high-efficiency removal of various impurities and guaranteeing water quality.

[0010] The entire unit uses flange connections, which facilitates the disassembly and cleaning of each component. The design of the cover and sleeve makes it easy and quick to remove and clean the magnetic rod and filter element. Attached Figure Description

Detailed Implementation

[0016] like Figure 1-4As shown: A filter shut-off valve includes a shut-off valve 1, with a filter 2 on the right side of the shut-off valve 1. The filter 2 has a shell structure and includes a filter tube 16 and a sleeve 5. The filter tube 16 has an opening at the bottom, and one end of a connecting pipe 3 and one end of a connecting pipe 4 are fixedly connected to the left and right sides of the outer wall of the filter tube 16, respectively. A flange is provided at the other end of the connecting pipe 3, which is connected to the inlet end of the shut-off valve 1 through the flange. The sleeve 5 is threadedly connected to the bottom inner wall of the filter tube 16, and a filter element 6 is slidably inserted into the sleeve 5. The top of the filter element 6 abuts against the inner top wall of the filter tube 16, and the outer wall of the filter element 6 abuts against the ends of the connecting pipe 3 and the connecting pipe 4 located inside the filter tube 16. The right side of pipe 16 has a magnetic rod box 7. The left side wall of the magnetic rod box 7 is fixedly connected to the connecting pipe 3 8. The left end of the connecting pipe 3 8 and the right end of the connecting pipe 2 4 are respectively provided with flanges. The left end of the connecting pipe 3 8 and the right end of the connecting pipe 2 4 are connected by flanges. The right side wall of the magnetic rod box 7 is fixedly connected to the water inlet pipe 9. Several guide plates 10 are fixedly connected to the front and rear inner walls of the magnetic rod box 7. Two guide plates 10 are grouped together. There is a gap between the two guide plates 10 in each group. The four groups of guide plates 10 are distributed in a rectangular shape. The magnetic rod 11 is located between the front and rear groups of guide plates 10. The magnetic rod 11 extends back and forth and is stacked up and down. The magnetic rod 11 slides with the guide plate 10. The top of the magnetic rod box 7 is fitted with a box cover 12.

[0017] Connecting plate 13 is fixedly connected to the top center of the front and rear side walls of magnetic rod box 7, and connecting plate 24 is fixedly connected to the bottom center of the front and rear side walls of box cover 12. Locking stud 15 passes through the top of connecting plate 24, and locking stud 15 is slidably connected to connecting plate 24. Locking stud 15 is threadedly connected to connecting plate 13.

[0018] Water first enters the magnetic rod box 7 through the water inlet pipe 9. Inside the magnetic rod box 7, the water flows through the magnetic rod 11, which adsorbs metal impurities in the water, thus performing preliminary filtration.

[0019] After being filtered by the magnetic rod 11, the water continues to flow into the filter 2 through the connecting pipe 3 8 and the connecting pipe 2 4. The filter element 6 inside the filter 2 further filters out other impurities in the water, such as particulate matter and suspended solids.

[0020] The filtered water eventually enters the shut-off valve 1 through connecting pipe 3.

[0021] When it is necessary to clean the magnetic rod 11, loosen the locking stud 15. The connecting plate 13 and the connecting plate 2 14 will no longer be connected. After removing the cover 12, the magnetic rod 11 can be taken out for cleaning. When cleaning the filter element 6, remove the filter element 6 by unscrewing the sleeve 5.
