Technical Field

[0001] The present application relates to the technical field of regulating valves, and in particular to an anti-scouring regulating valve body structure. Background Art

[0002] A regulating valve is a device used to control the flow, pressure, or temperature of a fluid. It is commonly used in industrial automation systems to ensure that the fluid in the system operates within a predetermined parameter range. The desired flow rate is maintained by controlling the opening of the regulating valve to control the fluid flow.

[0003] After searching, for example, the patent with announcement number CN204083261U specifically discloses a single-seat regulating valve structure. This patent further improves the sealing performance of the valve body by matching the inclination angles of the valve core and the inner wall of the valve seat.

[0004] However, when the valve body is dealing with fluids with high particle content or high flow rates, the high-frequency scouring of the fluid will cause wear on the valve body and its internal components, which not only reduces the sealing performance of the valve body but also affects its service life. Therefore, it is necessary to provide an anti-scouring regulating valve body structure to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] like Figure 1-Figure 2 As shown, the present application provides an anti-scour regulating valve body structure, including a valve body 1, a feed port 11 is provided on one side of the valve body 1, a discharge port 12 is provided on the other side of the valve body 1, and a transverse S-shaped flow channel (not marked in the figure) is provided between the feed port 11 and the discharge port 12, which is used to pass fluid.

[0032] At the same time, a lower flange 13 is fixedly mounted on the upper end of the valve body 1. The lower flange 13 is connected to the flow channel. A valve disc 14 is provided in the lower flange 13. The valve disc 14 is located in the flow channel and is used to block the feed port 11 and the discharge port 12. An adjustment mechanism 2 is provided on the upper end of the valve disc 14 to facilitate adjustment of the position of the valve disc 14.

[0033] like Figure 2-Figure 3As shown, the regulating mechanism 2 has a matching sleeve 21 disposed above the valve disc 14, and an upper flange 22 is fixedly mounted on the lower end of the matching sleeve 21. The upper flange 22 and the lower flange 13 correspond to each other, and both the upper flange 22 and the lower flange 13 are provided with mounting holes (not shown in the figure). Fixing bolts 23 are provided in the mounting holes. The fixing bolts 23 are used to fix the upper flange 22 and the lower flange 13, thereby fixing the matching sleeve 21 to the upper end of the valve body 1;

[0034] At the same time, the internal thread of the mating sleeve 21 is connected to a screw rod 25, the upper end of the screw rod 25 is fixedly mounted with a handle 26, and the lower end of the screw rod 25 is rotatably connected to a drive shaft 24, and the drive shaft 24 is slidably connected to the interior of the mating sleeve 21 and passes through the upper flange 22. The lower end of the drive shaft 24 is fixedly mounted on the upper end of the valve disc 14, so that the operator can rotate the handle 26 to rotate the screw rod 25, so that the screw rod 25 moves up and down in the mating sleeve 21, and drives the drive shaft 24 to move up and down in the mating sleeve 21, thereby driving the valve disc 14 to move up and down in the flow channel, blocking the flow channel.

[0035] In order to improve the sealing performance of the valve disc 14 to the valve body 1, as Figure 4 As shown, a through hole 15 is provided between the transverse S-shaped flow channel. The through hole 15 is perpendicular to the feed port 11 and the discharge port 12, and the through hole 15 is coaxially arranged with the lower flange 13. Therefore, when the valve disc 14 descends to the through hole 15, the flow channel will be blocked.

[0036] Furthermore, a sealing ring 16 is fixedly mounted on the upper end of the through hole 15, and a convex ring 17 is fixedly mounted on the upper end of the sealing ring 16. Both the convex ring 17 and the sealing ring 16 are made of rubber. At the same time, a valve core 18 is fixedly mounted on the lower end of the valve disc 14. A matching groove 19 is provided between the valve core 18 and the valve disc 14, and the matching groove 19 cooperates with the convex ring 17.

[0037] Therefore, when the matching groove 19 and the protruding ring 17 cooperate with each other, that is, when the valve core 18 is attached to the upper end surface of the sealing ring 16, the valve disc 14 is at the lower end, and the through hole 15 is completely blocked and sealed. When the valve disc 14 is away from the lower end, the through hole 15 is opened to allow fluid to pass through the valve body 1.

[0038] In order to reduce the wear of the valve body 1 and its internal components caused by the high-frequency scouring of the fluid, Figure 2 and Figure 4 As shown, the inner part of the lower flange 13 is provided with a protective sleeve 3, the bottom of the protective sleeve 3 is fitted on the upper end of the sealing ring 16, and multiple groups of first rubber rings (not shown in the figure) are provided on the outer side of the protective sleeve 3 to improve the sealing between the protective sleeve 3 and the valve body 1;

[0039] At the same time, the protective sleeve 3 and the valve disc 14 cooperate with each other, and the outer wall of the valve disc 14 is also fixedly installed with a second rubber ring to improve the sealing between the protective sleeve 3 and the valve disc 14;

[0040] In addition, multiple groups of holes 31 are opened on the protective sleeve 3. It should be noted that when the valve flap 14 is away from the lower end and the through hole 15 is open, the valve flap 14 is located at the upper end of the hole 31. Therefore, the fluid entering from the feed port 11 will first hit the protective sleeve 3, and then enter the through hole 15 through the hole 31 and flow out from the discharge port 12.

[0041] If the protective sleeve 3 needs to be replaced, the fixing bolts 23 are first removed, and then the matching sleeve 21, the upper flange 22 and the valve disc 14 are pulled outwards, and then the protective sleeve 3 is taken out and replaced.

[0042] Therefore, by providing the protective sleeve 3, the high-frequency flushing of the fluid on the valve body 1 and its internal components is prevented, the wear of the valve body 1 is prevented, the sealing performance of the valve body 1 is ensured, and the service life is increased.

[0043] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
