Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a gate valve that can clean the filter screen. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate plate whose movement direction is perpendicular to the fluid direction. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves achieve sealing through contact between the valve seat and the gate plate. Typically, the sealing surface is overlaid with metal material to increase wear resistance. A search revealed existing technology publication number CN210920143U, which describes a gate valve with filtration and cleaning functions. This valve includes a valve body with an internal conveying chamber. A valve seat is fixedly connected to the upper end of the valve body, and a screw is threaded into the valve seat. The upper thread of the screw extends to the top of the valve seat and is fixedly connected to an adjusting handle. An outlet chamber is located in the middle of the conveying chamber. This invention, by adding a filter screen to the outlet and a waste chamber threaded to the lower end of the valve body, effectively filters wastewater particles during sewage filtration. Furthermore, when the outlet filter screen becomes clogged, a motor can be activated to rotate a scraper rod, thereby filtering impurities from the filter screen and effectively clearing the outlet. This design is simple, practical, and convenient.

[0003] In summary: In the above cases, although the filter screen was cleaned using a scraper bar, the scraper bar was unable to remove the impurities stuck on the filter screen. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a gate valve that can clean the filter screen, thereby solving the problem in the above-mentioned cases mentioned in the background art where, although the filter screen is cleaned by a scraper rod, the scraper rod is unable to scrape off and clean the impurities stuck on the filter screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gate valve for cleaning a filter screen, comprising a gate valve structure, wherein a filter structure is installed on one side of the gate valve structure;

[0006] The gate valve structure includes a gate valve body as the main body, and the outlet pipe and inlet pipe of the gate valve body are fixedly installed with a connecting plate, and a matching groove is opened on one side surface of the connecting plate.

[0007] The filter structure includes an installation pipe that is embedded and connected to the filter box, and an installation plate is fixedly installed at one end of the installation pipe. At the same time, a matching block that is embedded and fixedly connected to the matching groove is embedded on the surface of the installation plate.

[0008] By adopting the above technical solution, the matching blocks are set up to achieve the purpose of connection and matching.

[0009] Preferably, a recessed block is fixedly installed inside the filter box, and a filter screen is fitted inside the recessed block. At the same time, a sheet metal plate is fixedly installed above the filter screen, and the sheet metal plate is adsorbed and connected to the adsorption plate.

[0010] By adopting the above technical solution, the adsorption plate is set up to achieve adsorption and fixation.

[0011] Preferably, the adsorption plate is fixedly installed at the bottom of the box plate, and the box plate is installed inside the filter box at the top. At the same time, one side of the filter box is connected to a water delivery pipe with a connecting plate through another installation pipe and another installation plate.

[0012] By adopting the above technical solution, the setting can be achieved through the connection disk.

[0013] Preferably, the mounting tubes are provided in one set, and a mounting plate is embedded and fixedly installed at one end of each mounting tube.

[0014] By adopting the above technical solution, the installation tube is used to achieve the embedded installation connection.

[0015] Preferably, four recessed blocks are provided, and the recessed blocks are fixedly installed inside the filter box at equal intervals.

[0016] By adopting the above technical solution, the recessed blocks achieve a locking and fitting effect.

[0017] Preferably, four sheet metal plates are provided, and each sheet metal plate is fixed above a single filter screen.

[0018] By adopting the above technical solution, the iron sheet plate is used to fix and adsorb the material.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the gate valve that can clean the filter screen,

[0020] (1) This case solves the problem in the above case where, although the filter screen is cleaned by a scraper bar, the scraper bar cannot scrape off the impurities stuck on the filter screen. When the filter screen is clogged after long-term use, the box plate is pulled to separate the filter screen from the concave block. When the filter screen is separated from the concave block, it is convenient to disassemble and clean the clogged filter screen. Furthermore, the box plate can be separated from the filter box to ensure that the filter screen can be disassembled, cleaned, or replaced individually during the normal operation of the gate valve body.

[0021] (2) By using the connecting plate, matching groove, installation pipe, installation plate and matching block in the filter structure and gate valve structure, the situation where the overall filter box cannot be quickly disassembled or installed is solved. When the overall filter box needs to be disassembled or installed, the operator lifts the filter box and drives the matching block and matching groove to be separated by force, thereby facilitating the installation and disassembly of the overall filter box and the gate valve body.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a gate valve that can clean the filter screen, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a gate valve structure 1, which includes a gate valve body 101 as the main body. The outlet pipe and inlet pipe of the gate valve body 101 are fixedly mounted with a connecting plate 102. At the same time, a matching groove 103 is opened on one side surface of the connecting plate 102. The gate valve body 101 adopts the component settings in the prior art. When the gate valve body 101 is set using the components in the prior art, the normal operation of the overall gate valve body 101 is effectively guaranteed.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, a filter structure 2 is installed on one side of the gate valve structure 1. The filter structure 2 includes an installation pipe 201 that is embedded and connected to the filter box 202. There is one set of installation pipes 201, and one installation plate 203 is embedded and fixedly installed at one end of each installation pipe 201. When there are two of the above components, it not only reflects the symmetry of the installation of the above components, but also reflects the embedded and continuous conveying of the installation of the above components. Furthermore, when there are two of the above components, it reflects the practicality of the installation of the above components and the matching docking at both ends. The installation plate 203 is fixedly installed at one end of the installation pipe 201, and the surface of the installation plate 203 is embedded and fixedly connected to the matching groove 103.

[0032] Furthermore, in the above scheme, four recessed blocks 205 are fixedly installed inside the filter box 202, and these blocks are equidistantly fixed inside the filter box 202. By having four of these components, an equal number of filter screens 206 are effectively installed inside the filter box 202 to intercept and filter the discharged water. The use of four such components not only demonstrates the equidistant distribution of the components but also their interlocking connection. The recessed blocks 205... 5. An internally fitted filter screen 206 is installed, and a sheet metal plate 207 is fixedly installed above the filter screen 206. There are 4 sheet metal plates 207, and each sheet metal plate 207 covers and is fixed above a single filter screen 206. When the above components are installed and conveyed, this not only reflects the covering and fixing of the above components, but also reflects the adsorption, pulling and separation of the above components. Furthermore, the fact that there are 4 of the above components also reflects the fixed installation of the above components. The sheet metal plate 207 is adsorbed and connected to the adsorption plate 208.

[0033] Furthermore, in the above scheme, the adsorption plate 208 is fixedly installed at the bottom of the box plate 209, and the box plate 209 is installed inside the filter box 202. At the same time, one side of the filter box 202 is connected to the water delivery pipe 2010 with the same connecting plate 102 through another installation pipe 201 and another installation plate 203.

[0034] In the above scheme, when the gate valve body 101 is in operation, external water is transported to the filter box 202 through the water delivery pipe 2010 for filtration. The filtered water enters the gate valve body 101 and is transported to another filter box 202 and discharged through another water delivery pipe 2010. When the filter screen 206 becomes clogged after long-term use, the box plate 209 is pulled to separate the filter screen 206 from the concave block 205. When the filter screen 206 is separated from the concave block 205, it is convenient to disassemble and clean the clogged filter screen 206. Furthermore, the box plate 209 can be separated from the filter box 202 by force, thus ensuring that the filter screen 206 can be disassembled, cleaned, or replaced individually during the normal operation of the gate valve body 101.
