Description

Technical Field

[0001] This utility model relates to the field of high-pressure ball valve technology, and in particular to an ultra-high-pressure free-forged ball valve. Background Technology

[0002] When forged steel high-pressure ball valves are used for fluid regulation and control, they are often easily blocked by impurities contained in the fluid. These impurities can clog the high-pressure ball valve or pipeline, making it difficult to clean them and causing the high-pressure ball valve to malfunction.

[0003] Therefore, in the prior art, a forged steel high-pressure ball valve, with publication number CN218992423U, has through pipes fixed on both sides of the valve body, and the opposite ports of the through pipes are connected to flange connecting seats through a connecting mechanism. A filter plate is fixedly installed inside the through pipe, which can play a filtering role. By disassembling the bolts on flange ring one and flange ring two in the connecting mechanism, the through pipe and the valve body can be disassembled as a whole, and then the surface of the filter plate in the through pipe can be treated.

[0004] The device filters impurities in liquids by using filter plates. However, since the filter plates are fixed inside the channel, the entire device needs to be disassembled from the pipeline to clean them, which is a troublesome process and makes the actual user experience of the device poor. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose an ultra-high pressure free forging ball valve.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an ultra-high pressure free forging ball valve, comprising a valve body, a ball valve body, and a filter plate. The valve body has an inlet end and an outlet end on both sides. The valve body has a port on one side perpendicular to the central axis of the inlet end and the outlet end. The port is at the same height as the inlet end and is threadedly connected to a cover plate. A push rod is slidably inserted into the central axis of the cover plate. A protrusion is provided at one end of the push rod located inside the valve body. The filter plate is inserted into a flow channel hole on the ball valve body. Both ends of the flow channel hole on the ball valve body are threadedly connected to annular baffles for fixing the filter plate. The annular baffles are provided with snap-fit ​​grooves for engaging with the protrusion.

[0007] Preferably, there are two filter plates that are threadedly connected to each other, and one of the filter plates has a sleeve fixedly connected to its end face that is inserted into the end face of the other filter plate.

[0008] Preferably, the valve body also has a port on the other side perpendicular to the inlet and outlet ends, and a cover plate is also installed at the port on the other side of the valve body.

[0009] Preferably, a support shell is fixedly installed on the top of the valve body, and a valve stem located inside the support shell is fixedly installed on the top of the ball valve body.

[0010] Preferably, the top of the valve stem is connected to a handle that is rotatably mounted to the support shell via a pin, and the end of the push rod located outside the valve body is also fixed with a handle, and the handle located at the push rod is in clearance fit with the cover plate located at the push rod.

[0011] Preferably, needle roller bearings are provided between the valve stem and the support housing, as well as between the handle that is inserted into the valve stem and the support housing.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting the filter plate to be inserted into the flow channel hole on the ball valve body, the filter plate can be taken out of the valve through the port when cleaning is required, without disassembling the entire device, thus simplifying the cleaning process of the filter plate.

[0014] 2. In this utility model, by setting a port on the other side of the valve body, when personnel want to simply rinse the filter plate, they only need to open the two covers and align the two filter plates with the two ports respectively to achieve the rinsing purpose.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, an ultra-high pressure free forging ball valve includes a valve body 1, a ball valve body 7, and a filter plate 10. The valve body 1 has an inlet end 4 and an outlet end 5 on both sides. A port 16 is opened on one side of the valve body 1 perpendicular to the central axis of the inlet end 4 and the outlet end 5. The port 16 is at the same height as the inlet end 4 and is threadedly connected to a cover plate 6. A push rod 9 is slidably inserted at the central axis of the cover plate 6. A protrusion 12 is provided at one end of the push rod 9 located inside the valve body 1. The filter plate 10 is inserted into the flow channel hole on the ball valve body 7. Both ends of the flow channel hole on the ball valve body 7 are threadedly connected to an annular baffle 14 for fixing the filter plate 10. The annular baffle 14 is provided with a snap-fit ​​groove 13 for snapping with the protrusion 12.

[0023] This technical solution involves inserting the filter plate 10 into the flow channel hole on the ball valve body 7. When cleaning is required, the filter plate 10 can be removed from the valve through one of its ports 16. Specifically, the ball valve body 7 is rotated so that one end of the flow channel hole aligns with the push rod 9. The push rod 9 is then pressed, causing the protrusion 12 fixed at one end of the push rod 9 to move towards the annular baffle 14 and enter the locking groove 13. At this point, the push rod 9 is rotated, causing the annular baffle 14 to rotate and exit from the flow channel hole. Furthermore, the push rod 9 is located at the central axis of the cover plate 6. Rotating the cover plate 16 allows it to rotate out of the valve body 1. The rotated cover plate 6 and annular baffle 14 are then removed, allowing the filter plate 10 to be pulled out of the valve 1.

[0024] like Figure 3 and Figure 4 As shown, there are two filter plates 10, which are threadedly connected to each other. One filter plate 10 has a sleeve 11 fixedly connected to its end face, which is inserted into the end face of the other filter plate 10.

[0025] By adopting this technical solution, two filter plates 10 are set so that the liquid can undergo double filtration when it flows from the inlet end 4 through the two filter plates 10, which makes the filtration effect of the device better. When the liquid flow rate through the valve is fast, the impact force of the water flow on the filter plate 10 near the inlet end 4 will be relatively large. By setting the sleeve 11, the filter plate 10 near the outlet end 5 can be supported at the central axis of the filter plate 10 near the inlet end 4, preventing it from being deformed due to the impact of the water flow.

[0026] like Figure 2 and Figure 3 As shown, a port 16 is also provided on the other side of the valve body 1, perpendicular to the inlet end 4 and the outlet end 5, and a cover plate 6 is also installed at the port 16 on the other side of the valve body 1.

[0027] Using this technical solution, by opening a port 16 on the other side of the valve body 1 perpendicular to the inlet end 4 and the outlet end 5, when personnel want to simply rinse the filter plate 10, they only need to rotate the cover plate 6 located at the push rod 9 to remove it from the valve body 1, and then remove the cover plate 6 on the other side of the valve body 1 by tightening the bolts, and connect it to a rinsing device, such as a high-pressure water pump. After aligning the two ends of the flow channel hole in the ball valve body 7 with the two ports 16 where the cover plate 6 has been removed, the rinsing device will work to flush out the impurities on the surface of the filter plate 10.

[0028] like Figure 2 and Figure 4 As shown, a support shell 2 is fixedly installed on the top of the valve body 1, and a valve stem 15 located inside the support shell 2 is fixedly installed on the top of the ball valve body 7. A handle 3 that is rotatably installed with the support shell 2 is inserted into the top of the valve stem 15 through a pin. A handle 3 is also fixed at one end of the push rod 9 located outside the valve body 1. The handle 3 located at the push rod 9 is in clearance fit with the cover plate 6 located at the push rod 9.

[0029] By adopting this technical solution, a handle 3 is provided to facilitate personnel to rotate the handle 3 and the push rod 9. A certain gap is provided between the handle 3 located at the push rod 9 and the cover plate 6 located at the push rod 9 to facilitate personnel to press the push rod 9.

[0030] like Figure 2 and Figure 3 As shown, needle roller bearings 8 are provided between the valve stem 15 and the support shell 2, as well as between the handle 3 that is inserted into the valve stem 15 and the support shell 2.

[0031] By adopting this technical solution and setting the needle roller bearing 8, the friction between the valve stem 15 and the support shell 2, as well as between the handle 3 and the support shell 2, can be reduced, preventing the valve stem 15 from seizing due to excessive pressure.

[0032] Working principle: When the filter plate 10 needs to be cleaned, rotate the ball valve body 7 and align one end of the flow channel hole inside the ball valve body 7 with the push rod 9. At this time, press the push rod 9 so that the protrusion 12 fixed at one end of the push rod 9 enters the channel groove 13. Rotate the push rod 9, and the rotation of the push rod 9 will drive the annular baffle 14 to rotate, thereby causing the annular baffle 14 to rotate out of the flow channel hole. Then rotate the cover plate 16 so that it rotates out from the side of the valve body 1. Remove the rotated cover plate 6 and the annular baffle 14, and the filter plate 10 can be pulled out of the valve body 1 for cleaning.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
