Description

Technical Field

[0001] The utility model relates to the field of ball valves, in particular to a forged steel floating ball valve. Background Art

[0002] At present, a Chinese utility model with a publication number of CN218236212U discloses a technical field of a floating ball valve for a pipeline, and particularly relates to a floating ball valve for a pipeline, including a floating ball valve for a pipeline, including a valve seat, a storage chamber is connected to the top of the valve seat, an inlet pipe and a drain pipe are respectively arranged at both ends of the valve seat, a valve core is arranged on the inner side of the valve seat, a sealing assembly is arranged on the outer wall at both ends of the valve core, a rotating assembly is arranged on the top of the valve core, a filtering mechanism is arranged on the side of the valve seat close to the water inlet pipe, the filtering mechanism includes a filter disc, a plurality of groups of filter holes are arranged on the outer surface of the filter disc, the outer side of the filter disc is connected to the valve seat through a mounting assembly, a mounting plate is arranged on the inner side of the valve seat, a plurality of anti-clogging rods corresponding to the filter holes are inserted on the outer surface of one end of the mounting plate close to the filter disc, a support plate is fixedly connected to the top of one side of the mounting plate, and the top of the support plate extends to the valve seat and the top of the storage chamber. The utility model can filter impurities and clean the filter disc by itself.

[0003] Although the existing forged steel floating ball valve is equipped with a filter disc inside to filter the liquid entering from the liquid inlet end, there are still other problems during use, such as it is inconvenient to collect and process impurities. After the impurities in the liquid are intercepted, they will remain in the port and on the filter disc. When there are too many internal impurities, it can only be done by removing the pipe connected to the port, and then cleaning the impurities in the port and fixing it again. The operation is cumbersome and complicated, and it does not have a valve stem limiting function. When the water flow in the ball valve has a large impact or a person accidentally touches it, it is very easy to cause the valve core to rotate. The valve core will change the state of the ball valve when it is rotating, and its practicality is low. In order to solve the above problems, we propose a forged steel floating ball valve. Utility Model Content

[0004] The utility model aims to provide a forged steel floating ball valve, which solves the problem that the existing floating ball valve is inconvenient to clean the filter screen and has no valve stem limiting function.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a forged steel floating ball valve, comprising a valve body, a valve core is arranged inside the valve body, two ends of the valve body are respectively a liquid inlet end and a liquid outlet end, a guide end is integrally formed on the surface of the liquid inlet end, a filter cartridge is placed inside the guide end, and a bottom plate is bolted to the bottom of the guide end;

[0006] A valve stem is installed on the top of the valve core, a fixed disk is fixedly sleeved on the surface of the valve stem, a threaded rod is symmetrically welded on the top of the valve body, two sliding grooves are provided inside the fixed disk, and a nut is threadedly connected on the surface of the threaded rod.

[0007] The above technical solution can provide a valve stem limiting function to prevent the valve stem from rotating due to accidental contact or impact, thereby ensuring the state of the flow velocity inside the ball valve. At the same time, through the setting of the bottom plate, the bottom of the guide end can be closed, which is convenient for personnel to take out the filter cartridge, thereby facilitating the cleaning of the filter screen. The operation is simple and convenient, which reduces the burden on personnel to disassemble and reassemble the pipeline and is highly practical.

[0008] The utility model is further configured as follows: the filter cartridge is made of stainless steel, and the top of the filter cartridge is open.

[0009] By adopting the above technical solution, the filter cartridge has the characteristics of high strength, low density and excellent corrosion resistance.

[0010] The utility model is further configured as follows: a rotating rod is bolted on the surface of the valve stem.

[0011] By adopting the above technical solution and setting the rotating rod, it is convenient for personnel to rotate the valve stem.

[0012] The utility model is further configured as follows: flanges are fixedly sleeved on the surfaces of the liquid inlet end and the liquid outlet end.

[0013] By adopting the above technical solution, through the provision of the flange, it is convenient for personnel to fix the flange corresponding to the pipeline with screws.

[0014] The utility model is further configured as follows: a limit plate is installed inside the liquid inlet end.

[0015] By adopting the above technical solution, the filter cartridge can be limited by setting the limit plate to prevent the limit plate from shaking, and the liquid can be guided to flow into the interior of the filter cartridge.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The utility model first loosens the two nuts with a tool. After the nuts are loosened, the fixing plate and the valve stem are released. Then, a person holds the rotating rod to drive the valve stem to rotate. When the valve stem rotates, the valve core is driven to rotate together. When the valve core rotates to the liquid passing angle, the nuts can be tightened again. The utility model can have a valve stem limiting function to prevent the valve stem from rotating due to accidental contact or impact, thereby ensuring the state of the internal flow rate of the ball valve.

[0018] 2. The utility model fixes the ball valve and the pipeline with screws. After the ball valve is fixed, the liquid will enter the liquid inlet end through the pipeline. The liquid entering the liquid inlet end will enter the filter cartridge under the guidance of the limit plate. The pure liquid will continue to flow inward through the mesh of the filter cartridge, while the impurities will settle downward to the inside of the filter cartridge. The filter cartridge can be taken out by opening the bottom plate, which can facilitate the cleaning of the filter screen. The operation is simple and convenient, which reduces the burden of personnel on re-disassembly and re-assembly of the pipeline and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
