Description

Technical Field

[0001] This utility model belongs to the technical field of cage-type throttle valves, specifically relating to an erosion-resistant adjustable cage-type throttle valve. Background Technology

[0002] Cage-sleeve throttle valves are valves used for precise control of fluid flow. They are widely used in industries such as petroleum, chemical, and natural gas. Their design features an adjustable valve core combined with a cage structure to achieve fine fluid regulation. The cage is a cylindrical component with multiple small holes or grooves inside, surrounding the valve core. When the valve core moves up and down, the relative position between the cage and the valve core changes, adjusting the size of the fluid passage and thus controlling the flow rate. This design not only provides stable flow control but also effectively reduces noise and vibration, improving system stability. In short, cage-sleeve throttle valves, with their high precision, low noise, long lifespan, and diverse operating methods, play a vital role in industrial fluid control systems and are an indispensable key component of modern industry.

[0003] In existing technologies, traditional cage-type throttle valves cannot regulate the liquid flow rate, resulting in excessive fluid flow and waste. Utility Model Content

[0004] The purpose of this invention is to provide an erosion-resistant adjustable cage-type throttle valve, which aims to solve the problem that traditional cage-type throttle valves in the prior art cannot adjust the liquid flow rate, resulting in excessive fluid flow and waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An erosion-resistant adjustable cage-type throttle valve, comprising:

[0007] Main shell;

[0008] The control assembly includes a top seat, a baffle, a control rod, a water outlet frame, and a control valve. The top seat is fixedly connected to the surface of the main housing. The control rod is rotatably connected to the top seat and the main housing. The control valve is fixedly connected to the circumferential surface of the control rod. The baffle is fixedly connected to one end of the control rod. The water outlet frame is fixedly connected to the inner wall of the main housing. The baffle is rotatably connected to the inner wall of the water outlet frame.

[0009] A telescopic assembly is disposed on one side of the top seat.

[0010] In a preferred embodiment of this utility model, the telescopic assembly includes a hydraulic pump, a telescopic rod, and a sealing plate. The telescopic rod is rotatably connected to the inner wall of the control rod, the sealing plate is fixedly connected to one end of the telescopic rod, and the hydraulic pump is fixedly connected to the other end of the telescopic rod.

[0011] As a preferred embodiment of this utility model, a water outlet channel is fixedly connected to the surface of the main shell, and a second connecting ring is fixedly connected to the surface of the water outlet channel.

[0012] As a preferred embodiment of this utility model, a water inlet channel is fixedly connected to the surface of the main shell, and a first connecting ring is fixedly connected to the surface of the water inlet channel.

[0013] As a preferred embodiment of this utility model, all parts inside the main shell are coated with a layer of tungsten carbide.

[0014] As a preferred embodiment of this utility model, the surface of the top seat has multiple holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this solution, the inlet and outlet pipes are first fixed by the first and second connecting rings. When the liquid flows into the main shell through the inlet channel, the pressure of the liquid will push the sealing plate upward. At this time, the liquid can flow to the upper part of the sealing plate. Then, when the liquid passes through the opening on the surface of the baffle, the control valve is rotated. At this time, the control rod will rotate. Since the outlet frame is rotatably connected to the circumferential surface of the baffle, rotating the outlet frame can gradually block the gap on the baffle. The size of the blocked gap controls the flow rate of the liquid.

[0017] 2. In this design, all parts inside the main housing are coated with a layer of tungsten carbide to enhance their erosion resistance and increase the service life of the throttle valve; multiple holes are opened on the surface of the top seat for connecting other related equipment.

[0026] An erosion-resistant adjustable cage-type throttle valve, comprising:

[0027] Main shell 1;

[0028] The control assembly includes a top seat 4, a baffle 9, a control rod 10, a water outlet frame 12, and a control valve 13. The top seat 4 is fixedly connected to the surface of the main housing 1. The control rod 10 is rotatably connected to the top seat 4 and the main housing 1. The control valve 13 is fixedly connected to the circumferential surface of the control rod 10. The baffle 9 is fixedly connected to one end of the control rod 10. The water outlet frame 12 is fixedly connected to the inner wall of the main housing 1 and is rotatably connected to the inner wall of the water outlet frame 12.

[0029] Telescopic assembly, which is located on one side of the top seat 4.

[0030] In a specific embodiment of this utility model, when the liquid passes through the opening on the surface of the baffle 9, the control valve 13 is rotated. At this time, the control rod 10 will rotate. Since the water outlet frame 12 is rotatably connected to the circumferential surface of the baffle 9, rotating the water outlet frame 12 can slowly block the opening on the baffle 9. The size of the blocked opening controls the flow rate of the liquid.

[0031] Please refer to the details. Figures 1-3 The telescopic assembly includes a hydraulic pump 5, a telescopic rod 6, and a sealing plate 11. The telescopic rod 6 is rotatably connected to the inner wall of the control rod 10, the sealing plate 11 is fixedly connected to one end of the telescopic rod 6, and the hydraulic pump 5 is fixedly connected to the other end of the telescopic rod 6.

[0032] In this embodiment: First, the hydraulic pump 5 is fixed on other related equipment. When the liquid enters the interior of the main shell 1, the pressure of the liquid will push the sealing plate 11 upward, and the liquid can then flow to the upper part of the sealing plate 11.

[0033] Please refer to the details. Figures 1-3The surface of the main shell 1 is fixedly connected to a water outlet 7, and the surface of the water outlet 7 is fixedly connected to a second connecting ring 3.

[0034] In this embodiment: the water outlet 7 is the outlet for liquid to flow out, and the surface of the second connecting ring 3 has multiple holes for connecting to the water outlet pipe.

[0035] Please refer to the details. Figures 1-3 The surface of the main shell 1 is fixedly connected to a water inlet channel 8, and the surface of the water inlet channel 8 is fixedly connected to a first connecting ring 2.

[0036] In this embodiment: the water inlet 8 is the inlet for liquid to flow in, and the surface of the first connecting ring 2 has multiple holes for connecting to the water inlet pipe.

[0037] Please refer to the details. Figures 1-3 All the parts inside the main shell 1 are coated with a layer of tungsten carbide.

[0038] In this embodiment, all parts inside the main housing 1 are coated with a layer of tungsten carbide to enhance their erosion resistance and increase the service life of the throttle valve.

[0039] Please refer to the details. Figures 1-3 Multiple holes are opened on the surface of the top seat 4.

[0040] In this embodiment, the surface of the top seat 4 has multiple holes for connecting other related devices.

[0041] It should be noted that the specific model of hydraulic pump 5 used shall be selected by those skilled in the art, and the above-mentioned hydraulic pump 5 and other related technologies are all existing technologies, which will not be elaborated upon in this solution.

[0042] The working principle and usage process of this utility model are as follows: First, the inlet and outlet pipes are fixed by the first connecting ring 2 and the second connecting ring 3. Then, when the liquid flows into the main shell 1 through the inlet channel 8, the pressure of the liquid will push the sealing plate 11 upward. At this time, the liquid can flow to the upper part of the sealing plate 11. Then, when the liquid passes through the opening on the surface of the baffle 9, the control valve 13 is rotated. At this time, the control rod 10 will rotate. Since the outlet frame 12 is rotatably connected to the circumferential surface of the baffle 9, rotating the outlet frame 12 can slowly block the notch on the baffle 9. The size of the blocked notch controls the flow rate of the liquid, thereby solving the problem that the traditional cage-type throttle valve cannot adjust the flow rate of the liquid, resulting in excessive fluid passing through and causing waste.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
