Description

Technical Field

[0001] This utility model relates to a filter, and more particularly to a Y-type butt welding filter. Background Technology

[0002] Y-type filters are an indispensable filtration device in pipeline systems for conveying media. They are typically installed at the inlet of pressure reducing valves, relief valves, positioning valves, or other equipment to remove impurities from the media, protecting the valves and equipment. Y-type filters feature advanced structure, low resistance, and convenient drainage. Suitable media include water, oil, and gas. Generally, the mesh size is 18-30 mesh for water, 10-100 mesh for air, and 100-480 mesh for oil. Basket filters mainly consist of connecting pipes, main pipes, filter baskets, flanges, flange covers, and fasteners. When liquid enters the filter basket through the main pipe, solid impurities are trapped inside, while clean fluid passes through the basket and exits through the filter outlet. Traditional products often use bolted connections or other threaded connections, which are prone to corrosion and blockage after prolonged use. Frequent opening and closing or exposure to temperature differences can also affect the sealing performance. Utility Model Content

Attached Figure Description

[0012] Figure 2 This is a cross-sectional structural diagram of the present invention. Detailed Implementation

[0013] like Figures 1-2 As shown, a Y-type weld bead filter includes a valve body 1, which has an inlet end 2, an outlet end 3, and a connecting end 4 connected in sequence. The inlet end 2 and the outlet end 3 are arranged along the same axis, and the connecting end 4 and the outlet end 3 form an angle of less than 90 degrees. The valve body 1 has a cavity 5 arranged along a Y-shaped path. This is a basic layout that sets basic constraints on each part. The cavity 5 has an opening 6, an opening 7, and an opening 8 at the connecting end 4. The opening 6 is located between the inlet end 2 and the connecting end 4, and the opening 8 is located between the connecting end 4 and the outlet end 3. A valve cover 9 with a weld bead connection is provided at the opening 7. A filter cylinder 10 is provided inside the connecting end 4. The filter cylinder 10 is radially parallel to the flow direction from the connecting end 4 to the outlet end 3. The valve cover 9 and the connecting end 4 are nested together to form a labyrinth seal. The opening 7 has a groove 11 on the outer edge of its side wall, and a sealing ring 12 is provided in the groove 11. Butt welding refers to a method of welding by placing the workpieces between two clamping devices, aligning their end faces, and then heating them at the contact point. Butt welding requires that the cross-sectional dimensions and shapes of the workpieces at the contact point be the same or similar to ensure uniform heating of the contact surfaces. In this embodiment, butt welding replaces the threaded connection structure, enhancing sealing and connectivity. Furthermore, to avoid potential butt welding defects, a labyrinth structure and rubber seals are also incorporated. These further improve sealing performance and also provide impact resistance and structural strength.

[0014] The inner wall of the connecting end 4 is provided with a groove 13, and the valve cover 9 is provided with an insert 14 that fits the groove 13. The inner wall of the connecting end 4 near the opening 6 is provided with a positioning groove 15, and the filter cylinder 10 abuts against the positioning groove 15. The design of the groove 13 and the positioning groove 15 helps to stabilize the filter cylinder 10 and can also achieve a labyrinth seal effect, that is, the medium achieves a throttling and sealing effect by passing through the tortuous gaps.

[0015] The connecting end 4 is also provided with an extension block 16 on its side wall. The extension block 16 and the insert block 14 abut against each other axially at the connecting end 4. The extension block 16 extends the valve cover 9 in a modified manner, making the connection between the valve cover 9 and the connecting end 4 tighter, and at the same time enhancing the double sealing effect. The filter cylinder 10 is mostly a mesh cylinder structure, which will not be elaborated or limited here.

[0016] A narrow channel 17 is provided between the inlet end 2 and the connecting end 4, and the diameter of the narrow channel 17 is smaller than the diameter of the inlet end 2 and the connecting end 4. The design of the narrow channel 17 creates a tube-like effect, which facilitates the acceleration of the medium at this point and its impact into the connecting end 4, while also allowing it to pass through the filter cylinder 10 more quickly and trap impurities. The valve cover 9 also has an inner groove that connects to the filter cylinder 10, providing space for the impact of the medium and reducing damage to the filter cylinder 10.
