[0026] The components include: 1. Blind flange with clamp; 2. Clamp; 3. Carbon steel main pipe; 4. Limiting plate; 5. Carbon steel branch pipe; 6. Filter screen; 7. Carbon steel round plate; 8. Clamp bolt. Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Reference Figure 1 As shown, the clamp-type straight-through filter of this embodiment includes a clamp blind plate 1, a clamp 2, a carbon steel main pipe 3, a limiting plate 4, a carbon steel branch pipe 5, a filter screen 6, a carbon steel round plate 7, and a clamp bolt 8;

[0029] The carbon steel main pipe 3 has a clamp blind flange 1 installed at its top. The clamp blind flange 1 is connected by clamps 2, allowing for quick and easy opening and closing. During routine maintenance, the clamp bolts 8 can be loosened to remove clamps 2, which in turn allows the clamp blind flange 1 to be removed, and the filter screen 6 can be taken out for cleaning and maintenance. This design is particularly suitable for the fire protection industry and secondary water supply applications.

[0030] In this embodiment, the clamp blind plate 1, clamp 2 and clamp bolt 8 are finished purchased parts.

[0031] Preferably, a groove is provided at the top of the carbon steel main pipe 3 to facilitate the subsequent installation of the clamp 2.

[0032] Among them, a carbon steel circular plate 7 is welded to the bottom of the carbon steel main pipe 3, so that the bottom of the carbon steel main pipe 3 forms a closed space.

[0033] In this design, holes are made on both sides of the shaft of the carbon steel main pipe 3, and carbon steel branch pipes 5 are welded to the two holes respectively. The two carbon steel branch pipes 5 are connected, thus forming a cross-shaped structure that runs through the top, bottom, left, and right of the clamp-type straight filter in this embodiment. The design is ingenious and the structure is compact. The outer end of the carbon steel branch pipe 5 is connected to the installation pipeline.

[0034] Preferably, a groove is provided at the outer end of the carbon steel branch pipe 5, and subsequent pipe installations are connected through the groove.

[0035] Preferably, the carbon steel main pipe 3 and the carbon steel branch pipe 5 are made of carbon steel pipe, which is readily available, inexpensive, and easy to use.

[0036] The carbon steel main pipe 3 is equipped with a filter screen 6 to filter and remove impurities from the water. The filter screen 6 can be easily and quickly removed from the carbon steel main pipe 3 for cleaning, ensuring a thorough cleaning.

[0037] Furthermore, the filter screen 6 is designed as a barrel-shaped structure with a bottom. The opening of the barrel-shaped structure is inclined and can cover the inlet end of the carbon steel branch pipe 5 on one side. In this way, during use, water and other fluids flow from the carbon steel branch pipe 5 on one side into the carbon steel main pipe 3. After being filtered by the filter screen 6, the filtered water and other fluids flow into the carbon steel branch pipe 5 on the other side. The waste and impurities obtained from the filtration settle to the bottom of the filter screen 6 by gravity. This can remove impurities from the water and other fluids, thereby protecting the normal operation of subsequent valves and pipeline equipment.

[0038] The filter screen 6 has a pore size of 30~100 mesh, which allows for strong throughput.

[0039] Preferably, the filter screen 6 is made of 304 stainless steel.

[0040] Preferably, the side of the carbon steel main pipe 3 is provided with a limiting structure for fixing the filter screen 6 and preventing the filter screen 6 from loosening and rotating.

[0041] More preferably, the side of the carbon steel main pipe 3 is welded with a limiting piece 4, as shown in the reference. Figure 3 As shown, a slot is provided at the upper end of the filter screen 6. The limiting piece 4 is a 2mm thick sheet structure that is inserted into and engaged in the slot at the upper end of the filter screen 6 to prevent the filter screen 6 from deflecting. In this embodiment, the limiting piece 4 is made of carbon steel plate.

[0042] The length of the clamp-type straight-through filter in this embodiment is 3-5 cm shorter than that of the Y-type filter of the same specification.

[0043] In this embodiment, the straight-through filter with clamps is made by welding the carbon steel main pipe 3, carbon steel branch pipe 5, limiting plate 4 and carbon steel round plate 7 into a whole. Then, clamp blind plate 1, clamp 2, filter screen 6 and clamp bolt 8 are installed. After installation, the whole is painted for corrosion protection.
