[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow diversion, sealing, and support. Among them, the commonly used elbow is a kind of connecting pipe fitting commonly used in the water distribution pipe fittings for domestic drinking water, which is used for the connection at the pipeline turning point to change the direction of the pipeline. It connects two pipes with the same or different nominal diameters, enabling the pipeline to make turns at various angles. At present, most elbow pipe fittings on the market are very prone to blockage during use. Moreover, due to the relatively large bending part, it is easier to block some flocculent or solid objects. If you want to clear the blockage, you need to invite professionals and equip with professional equipment, which is time-consuming and laborious. Content of the Utility Model

[0003] The purpose of the utility model is to provide an elbow with a filtering function for the deficiencies of the existing technology, so as to solve the problems proposed in the above background art that most elbow pipe fittings on the market are very prone to blockage during use. Moreover, due to the relatively large bending part, it is easier to block some flocculent or solid objects. If you want to clear the blockage, you need to invite professionals and equip with professional equipment, which is time-consuming and laborious.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An elbow with a filtering function includes an elbow structure, and preliminary filtering structures are installed on both sides of the elbow structure in a matching manner;

[0005] The elbow structure includes an elbow pipe body with flanges welded at both ends, and mounting grooves for facilitating the matching of components of the preliminary filtering structure are opened on the flanges. At the same time, a filter frame with a filter element is installed inside the elbow pipe body;

[0006] One end of the filter frame is welded and fixed to a through-hole disk, and the through-hole disk is fitted and installed with the flange.

[0007] By adopting the above technical solution, the internal matching installation is achieved through the provided filter frame.

[0008] Preferably, the preliminary filtering structure includes a through-hole connection disk with matching grooves on both sides, sealing rings are installed in the matching grooves in a matching manner, and a grille is welded and fixed in the through-hole connection disk.

[0009] By adopting the above technical solution, the installation and matching are achieved through the opened matching grooves.

[0010] Preferably, a fine filter screen is fitted and installed in front of the grille, and the through-hole connection disk is installed and connected with the flange through the mounting groove.

[0011] By adopting the above technical solution, the grid net is provided to achieve grid interception.

[0012] Preferably, the overall thickness range of the through-hole disc is set to 0.2 - 0.4 cm, and one set of the through-hole discs is installed.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: The elbow with a filtering function

[0019] (1) In this case, by providing the elbow structure, it solves the problem that most elbow pipe fittings on the market are very likely to be blocked during use. Moreover, due to the large bending part, it is easier to block some flocculent or solid objects. If you want to clear it, you need to invite professionals and equip with professional equipment, which is time-consuming and laborious. When the liquid enters the inside of the filter frame, the filter element inside the filter frame filters and intercepts the impurities in the liquid at this time. When the filter element and the filter frame filter and intercept the impurities in the liquid, it avoids the blockage of the inside of the elbow pipe body by the impurities. When it is necessary to disassemble, clean and replace the filter element and the filter frame, pull the through-hole disc to drive the filter frame to be separated from the elbow pipe body under force, so as to clean and replace the filter frame and the filter element;

[0020] (2) By providing the preliminary filtering structure, the above problems are solved. When the liquid is transported through the flange into the inside of the elbow pipe body, the liquid first passes through the fine filter screen and the grid net to preliminarily filter and intercept the impurities in the liquid at this time. When the impurities in the liquid are preliminarily intercepted and filtered, most of the impurities can be effectively intercepted on one side of the fine filter screen. When the fine filter screen is used for a long time, the operator pulls the through-hole connecting disc to be separated from the flange under force to replace the fine filter screen.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: An elbow with a filtering function, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , includes an elbow structure 1. The elbow structure 1 includes an elbow pipe body 101 with flanges 102 welded at both ends. And an installation groove 103 for facilitating the matching of the components of the preliminary filtration structure 2 is provided on the flange 102. At the same time, a filter frame 104 with a filter element 105 is installed inside the elbow pipe body 101. One end of the filter frame 104 is welded and fixed to a through-hole disc 106, and the through-hole disc 106 is fitted and installed with the flange 102. The overall thickness range of the through-hole disc 106 is set to 0.2 - 0.4 cm, and the through-hole disc 106 is installed in a set of 1. When the overall thickness of the above-mentioned components is set to 0.2 cm, it is thus possible to avoid the situation where the flanges 102 cannot be tightly installed and fixed when the overall thickness of the above-mentioned components is too thick. And when the overall thickness of the above-mentioned components is set to 0.2 cm, it effectively plays a connecting and sealing effect for the installation and fixation between the two flanges 102, thereby avoiding the situation of installation gaps between the flanges 102.

[0029] As shown in Figure 5As shown, preliminary filtering structures 2 are installed on both sides of the elbow structure 1. The preliminary filtering structure 2 includes a through-hole connecting plate 201 with mating grooves 202 on both sides. The overall shape of the through-hole connecting plate 201 is set in an "elliptical" structure. When the overall shape of the above-mentioned components is set in an "elliptical" structure, it is not only convenient for the operator to quickly extract and separate the above-mentioned components and push them down for installation, but also when the overall shape of the above-mentioned components is set in an "elliptical" structure, the axisymmetric installation of the above-mentioned components is reflected at the same time. And a sealing ring 203 is installed inside the mating groove 202. There is 1 group of sealing rings 203, and the sealing ring 203 is concentric with the mating groove 202. When there is 1 group of the above-mentioned components, it effectively seals the two sides of the through-hole connecting plate 201, and when the two are concentric, it not only reflects the matching installation of the two, but also reflects the concentric and coaxial matching installation of the two. And when the two are concentric, the practicability and matching installation sealing of the two are reflected at the same time. At the same time, a grille 204 is welded and fixed in the through-hole connecting plate 201.

[0030] In the above solution, further, a fine filter screen 205 is fitted and installed in front of the grille 204, and the through-hole connecting plate 201 is installed and connected to the flange 102 through the installation groove 103.

[0031] In the above solution, the liquid first passes through the fine filter screen 205 and the grille 204 to preliminarily filter and intercept the impurities in the liquid. When the impurities in the liquid are first preliminarily intercepted and filtered, most of the impurities can be effectively intercepted on one side of the fine filter screen 205. When the fine filter screen 205 is used for a long time, the operator pulls the through-hole connecting plate 201 and the flange 102 to be separated under force to replace the fine filter screen 205. The preliminarily filtered liquid enters the inside of the elbow pipe body 101 and is filtered and intercepted again by the filter frame 104 and the filter element 105.

[0032] The orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention in a simplified manner, 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, and thus cannot be understood as a limitation to the protection scope of the present invention.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
