Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, specifically a valve with a filtering function. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are also classified according to their material, such as cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valves. In current technology, valve filtration functions are relatively simple, unable to intercept and adsorb metal debris in water, and inconvenient for removing intercepted debris.

[0003] For example, the authorized patent document with application number CN202323177204.6 discloses a valve with an aluminum valve core, including a valve cover, a sealing assembly at the bottom of the valve cover, multiple extension plates fixedly connected to the four corners of the bottom of the valve cover, a valve body slidably connected to the bottom of the valve cover, a through groove on the top center of the valve body, multiple push rods slidably connected to the four corners of the inner wall of the valve body, a driving rod rotatably connected to the adjacent side of two push rods, a locking rod rotatably connected to the adjacent side of two driving rods, a spring at the top of the push rod, and a switch assembly at the top of the valve cover. In this utility model, it is convenient for workers to replace the valve core that needs maintenance, and the connection of the rubber ring and the sealing groove can ensure the sealing performance between the valve core and the valve body after replacement, and can effectively reduce the direct contact between the valve core and the valve body, reduce friction and wear, thereby improving the life and performance of the valve core.

[0004] The aforementioned patents have the problem that the valve filtration function is relatively simple, unable to intercept and adsorb metal debris in the water, and it is not convenient to remove the intercepted debris. Therefore, we need to provide a valve with filtration function. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a valve with a filtering function, comprising:

[0025] Valve body 1 and connecting pipe 2 connecting both sides of valve body 1;

[0026] A partition 3 is fixedly installed inside the valve body 1. A sealing filter element 4 is installed inside the partition 3. The sealing filter element 4 is used for preliminary filtration of the liquid flowing inside the valve body 1. The sealing filter element 4 is also used to seal the partition 3.

[0027] The sealing filter element 4 includes a guide tube 41 fixedly installed inside the partition plate 3. A floating cylinder 42 is movably sleeved inside the guide tube 41. A sealing sleeve 43 is fixedly installed on the surface of the floating cylinder 42. The top of the floating cylinder 42 penetrates through the top of the valve body 1 and extends thereto. A filter element 40 is installed inside the valve body 1. The filter element 40 is used to intercept impurities in the water flow passing through the valve body 1.

[0028] The filter element 40 includes a lower filter plate 401 fixedly installed inside the floating cylinder 42, and side filter plates 402 are embedded on both sides of the floating cylinder 42. Both side filter plates 402 are located at the bottom of the sealing sleeve 43.

[0029] In this embodiment, water enters through the connecting pipe 2 on one side of the valve body 1. The water flows into the area below the partition 3. By activating two cylinders 62, the push plate 61 is driven to rise. The push plate 61 pulls the floating cylinder 42 upward, so that the two side filter screens inside the floating cylinder 42 are located at the top of the partition 3. At this time, the water below the partition 3 can only enter the area above the partition 3 after passing through the lower filter plate 401 and the two side filter plates 402 inside the floating cylinder 42, thus playing a multiple interception function for impurities in the water flow.

[0030] When the bottom of the sealing sleeve 43 is in contact with the top of the guide tube 41 to seal, the valve body 1 is not connected and the valve body 1 is in the closed state. When the valve body 1 is in the open state, the sealing sleeve 43 does not contact the guide tube 41, and interception nets 9 are installed inside both connecting tubes 2 to intercept larger debris and prevent it from entering the valve body 1.

[0031] The bottom cover 72 is equipped with an electromagnet 73. The electromagnet 73 is powered by the power supply 8 to adsorb metal debris in the water flowing in the valve body 1 onto the adsorption layer 74. It has the function of intercepting metal debris. The bottom cover 72 is separated from the discharge pipe 71 by bolts, which makes it easy to remove debris from the adsorption layer 74 and clean the bottom of the lower filter plate 401.

[0032] The top of the valve body 1 is embedded with an abutment ring 5. The inside of the abutment ring 5 is movably sleeved with the surface of the float cylinder 42, and the inside of the abutment ring 5 is tightly fitted with the surface of the float cylinder 42.

[0033] The contact ring 5 is located at the top of the valve body 1 and serves to seal the top of the valve body 1.

[0034] It also includes a pusher 6, which is used for adjusting the height of the floating cylinder 42. The pusher 6 includes a pusher plate 61 fixedly installed on the top of the floating cylinder 42. Cylinders 62 are fixedly installed on both sides of the bottom of the pusher plate 61. Both cylinders 62 are installed on the surface of the valve body 1 through a fixing frame 63, and the two cylinders 62 are synchronous cylinders 62.

[0035] Specifically, starting the two cylinders 62 drives the push plate 61 to rise, and the push plate 61 pulls the floating cylinder 42 upward, so that the two side filters inside the floating cylinder 42 are located at the top of the partition plate 3.

[0036] It also includes a secondary filter element 7, which is installed at the bottom of the valve body 1. The secondary filter element 7 includes a discharge pipe 71 connected to the bottom of the valve body 1. A bottom cover 72 is installed at the bottom of the discharge pipe 71 by bolts. An electromagnet 73 is fixedly installed at the bottom of the bottom cover 72. An adsorption layer 74 is fixedly installed at the top of the bottom cover 72. The adsorption layer 74 is used to adsorb metal impurities in the water inside the valve body 1.

[0037] It is worth noting that an electromagnet 73 is installed at the bottom of the bottom cover 72. The electromagnet 73 is powered by the power supply 8 to adsorb metal debris in the water flowing in the valve body 1 onto the adsorption layer 74, which has the function of intercepting metal debris. The bottom cover 72 is separated from the discharge pipe 71 by bolts, which makes it easy to remove debris from the adsorption layer 74 and clean the bottom of the lower filter plate 401.

[0038] One side of the electromagnet 73 is connected to a power supply 8 via a wire, and the power supply 8 is fixedly installed on the surface of the valve body 1.

[0039] It is worth noting that the electromagnet 73 is powered by the power supply 8, which adsorbs metal debris in the flowing water inside the valve body 1 onto the adsorption layer 74.

[0040] Both connecting pipes 2 have a fixed intercepting net 9 installed inside;

[0041] Both connecting pipes 2 are equipped with intercepting nets 9 to intercept larger debris and prevent it from entering the valve body 1.

[0042] Water enters through the connecting pipe 2 on one side of the valve body 1. The water flows into the area below the baffle 3. By activating two cylinders 62, the push plate 61 is raised. The push plate 61 pulls the floating cylinder 42 upward, so that the two side filter screens inside the floating cylinder 42 are located at the top of the baffle 3. At this time, the water below the baffle 3 can only enter the area above the baffle 3 after passing through the lower filter plate 401 and the two side filter plates 402 inside the floating cylinder 42. This provides multiple interception functions for impurities in the water flow. An electromagnet 73 is installed at the bottom of the bottom cover 72. The electromagnet 73 is powered by the power supply 8. It adsorbs metal debris in the water flowing in the valve body 1 onto the adsorption layer 74, thus intercepting metal debris. The bottom cover 72 is separated from the discharge pipe 71 by bolts, which facilitates the removal of impurities on the adsorption layer 74 and allows for cleaning of the bottom of the lower filter plate 401.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
