DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the utility model in conjunction with the drawings and embodiments.

[0021] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] As Figures 1-5 shown, a fluorine-lined four-way pipe fitting filter: includes a four-way pipe housing 1, a fluorine-lined layer 2 is provided on the inner wall of the four-way pipe housing, and a mesh layer 3 for increasing the contact area between the inner wall of the four-way pipe housing and the fluorine-lined layer is provided on the inner wall of the four-way pipe housing. By increasing the biting area with the fluorine-lined layer through the mesh layer, the fluorine-lined layer is not easily detached.

[0024] In this embodiment, the specific structure of the mesh layer is: the mesh layer is composed of a plurality of strip-shaped protrusions 4 that are spaced and cross each other. The strip-shaped protrusions are welded to the inner wall of the four-way pipe housing. The strip-shaped protrusions can be existing bendable strip-shaped ropes such as soft iron wires. The welding method can be spot welding, that is, the intersection points of the strip-shaped protrusions are welded to the inner wall of the four-way pipe housing. When the fluorine-lined material is sprayed inside the four-way pipe housing to form the fluorine-lined layer, the body parts of the strip-shaped protrusions at the non-welded points will be buried in the fluorine-lined layer, and the welded points are connected to the inner wall of the four-way pipe housing, so that the fluorine-lined layer is connected to the inner wall of the four-way pipe housing and at the same time is connected to the strip-shaped protrusions, increasing the biting area with the fluorine-lined layer, making the fluorine-lined layer not easily detached.

[0025] In this embodiment, for reasonable design, the grids formed by the intersection of each strip-shaped protrusion are rhombuses.

[0026] In this embodiment, the four-way pipe housing includes a vertical main pipe 5, and two horizontal branch pipes 6 are symmetrically distributed on the outer wall of the vertical main pipe. One end of each of the two horizontal branch pipes is communicated with the vertical main pipe, that is, the horizontal branch pipes are located on both sides of the vertical main pipe. The upper end of the vertical main pipe is the input end and the lower end is the output end. Filter mechanisms 7 are installed on the output ends of the horizontal branch pipes and the output end of the vertical main pipe. During use, large impurities are blocked by the filter mechanisms.

[0027] In this embodiment, flange plates 8 are welded to both ends of the vertical main pipe and the output ports of the horizontal branch pipes. Annular grooves 9 for accommodating the filtering mechanism are provided on the flange plates at the output ends of the horizontal branch pipes and the flange plates at the output ends of the vertical main pipe. The filtering mechanism is directly installed through the annular grooves on the flange plates. When the filtering mechanism is generally connected at present, the flange plates on the four-way pipe housing, the plate body of the filtering mechanism, and the flange plates of other butt-jointed pipes are butt-jointed in sequence. Then, a sealing gasket is clamped between the flange plate on the four-way pipe housing and the plate body of the filtering mechanism, and a sealing gasket is clamped between the plate body of the filtering mechanism and the flange plates of other butt-jointed pipes. Finally, the connection is achieved through bolts. This connection has two connection positions, increasing the risk of leakage. It enables the flange plate to be directly butt-jointed with other subsequent butt-jointed pipes, and the filtering mechanism no longer has a connection relationship with the butt-jointed pipes, reducing the connection points and further reducing the risk of leakage.

[0028] In this embodiment, for reasonable design and convenient installation of the filtering mechanism, the annular groove is located on the inner edge of the flange plate. The inner edge of the annular groove communicates with the corresponding vertical main pipe or horizontal branch pipe nozzle to form an inner stepped surface. At the same time, for reasonable design, the annular groove and the corresponding vertical main pipe or horizontal branch pipe nozzle are concentric.

[0029] In this embodiment, for reasonable design, the specific structure of the filtering mechanism is as follows: The filtering mechanism includes an annular mounting plate 10. A filter screen 11 is provided on the inner hole of the annular mounting plate. The ring width of the annular mounting plate is the same as the ring width of the annular groove, and the thickness of the annular mounting plate is not greater than the groove depth of the annular groove. The annular mounting plate is screwed to the annular groove by using countersunk bolts for connection, which also prevents the bolts from interfering with the flange plates of the butt-jointed pipes.

[0030] In this embodiment, a pressure relief pipe 12 is connected to the outer pipe wall of the vertical main pipe near the upper input port. The pressure relief pipe is communicated with the vertical main pipe. A connecting flange plate 13 is provided at the output port of the pressure relief pipe. The function of the pressure relief pipe is that once the filtering mechanisms at the three output ports are blocked by large impurities, in order to avoid excessive liquid pressure in the pipeline, resulting in leakage at each connection of the pipeline due to excessive pressure, a pressure relief pipe is set up to relieve the pressure of the pipeline. A switching valve such as an existing plug valve can be connected to the output port of the pressure relief pipe through the connecting flange plate.

[0031] In this embodiment, when using the structure of this device on a large pipeline, in order to enhance the overall structural strength, annular reinforcement plates 14 are welded on the outer walls of the vertical main pipe near both ends (i.e., the output port and the input port), on the outer wall of the horizontal branch pipe near the output port, and on the outer wall of the pressure relief pipe near the output port. A number of connecting rib plates 15 are circumferentially distributed between the annular reinforcement plates and the corresponding flange plates or connecting flange plates, and the connecting rib plates are fixedly welded to the corresponding vertical main pipe, horizontal branch pipe, and pressure relief pipe.

[0032] If terms such as "first" and "second" are used in this article to define components, those skilled in the art should be aware that the use of "first" and "second" is only for the convenience of differentiating components in the description. Unless otherwise stated, the above terms have no special meaning.

[0033] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, using bolts or screws), or it can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutually fixed connection can also be replaced by an integral structure (for example, manufactured by an integral casting process) (except when it is obviously impossible to adopt the integral forming process).

[0034] In addition, for the positional relationships used in any of the technical solutions disclosed in the present utility model, such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this patent, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation of this patent. And for the terms used to represent shapes in any of the technical solutions disclosed in the present utility model, unless otherwise stated, their meanings include shapes similar, analogous, or close to them.

[0035] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.
