Description

Technical Field

[0001] This utility model relates to the field of heat-insulated jacketed ball valve technology, and in particular to a highly corrosion-resistant heat-insulated jacketed ball valve. Background Technology

[0002] In industrial production, numerous fluid transport scenarios place stringent demands on valves. In the chemical industry, the transport of large quantities of corrosive media, such as strong acids and alkalis, makes ordinary valves susceptible to corrosion and leakage, impacting production efficiency and posing serious safety hazards. In the oil and natural gas energy industries, temperature fluctuations are a frequent concern during fluid transport. In low-temperature environments, fluids easily solidify, hindering transport and increasing energy consumption. Traditional valves lack effective insulation measures, making it difficult to maintain suitable fluid temperatures. In industries with extremely high hygiene and product quality requirements, such as food and pharmaceuticals, valve materials and temperature control directly affect product quality. Corrosion of valves or improper temperature control can lead to product contamination and deterioration. Existing valves are significantly inadequate in terms of corrosion resistance, insulation, and precise control, failing to meet the growing demands of these industries. Therefore, the development of a jacketed ball valve with high corrosion resistance, efficient insulation, and precise control of fluid flow and on / off characteristics is urgently needed to adapt to complex operating conditions and ensure safe, stable, and efficient production operations.

[0003] Existing devices struggle to maintain stable fluid temperatures. In low-temperature environments or when transporting temperature-sensitive fluids, the fluids are prone to crystallization and solidification, hindering normal transport. The lack of precision in regulation and intelligent temperature control fails to meet production requirements. Furthermore, the mounting methods for temperature control devices are cumbersome and difficult to disassemble and assemble quickly. Utility Model Content

Two baffles are fixedly connected to the inside of the heating shell respectively. Two arc-shaped connecting plates are fixedly connected to the inner wall of the heating shell respectively. Several heating copper pipes are fixedly connected to the opposite inner sides of the two arc-shaped connecting plates respectively.

[0013] Compared with the prior art, this utility model provides a highly corrosion-resistant and heat-insulating jacketed ball valve, which has the following beneficial effects:

[0014] 1. This highly corrosion-resistant, heat-insulating jacketed ball valve controls the flow and flow rate of fluid within the valve pipeline by rotating a control handwheel to drive the internal rotation of the ball valve body. A thermostatic mechanism is fixed to both sides of the ball valve body and the two ball valve pipelines via a fixing mechanism. The thermostatic mechanism controls the internal temperature of the ball valve pipelines and the ball valve body through heat conduction. Thus, the internal temperature of the ball valve body and the ball valve pipelines is precisely regulated through heat conduction, preventing problems such as crystallization, solidification, or vaporization of the fluid due to temperature fluctuations. This ensures that the fluid always maintains good fluidity, maintains smooth pipeline transportation, and allows for rapid assembly. The structure is stable and ensures high efficiency in heat conduction.

[0015] 2. This highly corrosion-resistant and heat-insulating jacketed ball valve, by inserting two sliders into the internal grooves of the fixed frame, and then placing a movable limiting block around the movable hollow tube, rotates the movable limiting block so that the upper and lower protrusions of the movable hollow tube are engaged in the limiting groove on one side of the movable limiting block. Then, rotates the movable disc, driving the threaded screw to rotate. The internal thread of the movable hollow tube engages with the threaded screw, causing the movable hollow tube to move left and right within the limiting pipe. The movable hollow tube drives the movable limiting block, thereby clamping and fixing the two fixed blocks, thus fixing the two arc-shaped connecting blocks on both sides of the ball valve pipe. The arc-shaped connecting blocks drive the connecting strip, and the connecting strip drives the heating shell. Thus, a stable and secure installation of the heating shell is achieved, ensuring a tight fit between the thermostatic mechanism, the ball valve ball, and the ball valve pipe, making heat transfer more efficient and improving the overall stability of the ball valve structure.

[0016] 3. This highly corrosion-resistant, heat-insulating jacketed ball valve allows hot water or other heating media to flow through the inlet. The media flows inside the heating shell, exchanging heat with the ball valve body and the ball valve pipeline. The heating copper tube can further heat the internal media as needed. A temperature monitor tracks the internal temperature in real time and feeds the data back to the controller. When the temperature is too high, the controller can reduce the heating power of the heating copper tube; conversely, when the temperature is too low, it increases the heating. The used heating media flows out through the outlet. This system accurately maintains the temperature of the fluid inside the ball valve body and the ball valve pipeline, effectively preventing crystallization, solidification, and other adverse phenomena caused by temperature fluctuations. It ensures the normal transport of fluid in the pipeline and achieves intelligent temperature regulation, reducing energy consumption and improving energy efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] A highly corrosion-resistant and heat-insulating jacketed ball valve, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes a ball valve body 10, ball valve pipes 9 are fixedly connected to both sides of the ball valve body 10, a control handwheel 4 is movably connected to the top of the ball valve body 10, flanges 7 are fixedly connected to both sides of the two ball valve pipes 9, a heating shell 2 is movably connected to both sides of the ball valve body 10 and the two ball valve pipes 9, and a controller 1 is fixedly connected to one side of the heating shell 2.

[0029] The heating shell 2 is fixedly connected to a thermostat mechanism 8. The upper and lower ends of the ball valve ball 10 and the two ball valve pipes 9 are respectively movably connected to two connecting strips 5. The heating shell 2 is fixedly connected to one side of the two connecting strips 5. Two arc-shaped connecting blocks 6 are movably connected to both sides of the two ball valve pipes 9. The arc-shaped connecting block 6 is fixedly connected to one side of the connecting strip 5. The fixing mechanism 3 is fixedly connected around the two arc-shaped connecting blocks 6. The controller 1 is model RWD60.

[0030] During operation, rotating the control handwheel 4 drives the internal rotation of the ball valve ball 10, thereby controlling the flow and flow rate of the fluid in the ball valve pipeline 9. The constant temperature mechanism 8 is fixed on both sides of the ball valve ball 10 and the two ball valve pipelines 9 by the fixing mechanism 3. The constant temperature mechanism 8 controls the internal temperature of the ball valve pipeline 9 and the ball valve ball 10 through heat conduction. Thus, the internal temperature of the ball valve ball 10 and the ball valve pipeline 9 is precisely regulated through heat conduction to prevent problems such as crystallization, solidification or vaporization of the fluid due to temperature fluctuations, ensuring that the fluid always maintains good fluidity, maintaining smooth pipeline transportation, and at the same time, it can be quickly assembled, with a stable structure and ensuring high efficiency of heat conduction.

[0031] To ensure that the two heating shells 2 can be fixed on both sides of the ball valve ball 10, such as Figure 3 and Figure 4As shown, the fixing mechanism 3 includes a fixing frame 301, a movable disc 302, a fixing block 303, a slider 304, a movable limiting block 305, a movable hollow tube 306, a limiting pipe 307, and a threaded screw 308. The two fixing blocks 303 are respectively fixedly connected to the top of the two arc-shaped connecting blocks 6, and the two sliders 304 are respectively fixedly connected to the bottom of the two arc-shaped connecting blocks 6. The top of the fixing frame 301 is movably connected to one side of the fixing block 303.

[0032] Furthermore, a sliding groove is provided at the top of the inner part of the fixed frame 301, and two sliders 304 are slidably connected inside the sliding groove of the fixed frame 301. The limiting pipe 307 is movably connected inside the two fixed blocks 303, and the limiting pipe 307 is fixedly connected to one side of the fixed frame 301. A slide rail is provided on the inner wall of the limiting pipe 307, and a movable hollow tube 306 is movably connected inside the limiting pipe 307. A protrusion and a slide bar are respectively provided at the upper and lower ends of the movable hollow tube 306.

[0033] The threaded screw 308 is movably connected to the inside of the top of the fixed frame 301, and is also movably connected to the inside of the movable hollow tube 306. The movable hollow tube 306 has an internal thread. The movable disc 302 is fixedly connected to one side of the threaded screw 308. The movable limiting block 305 is movably connected to the periphery of the movable hollow tube 306. The inner wall of the movable limiting block 305 also has a slide rail, and a limiting groove is provided on one side of the movable limiting block 305.

[0034] During operation, the two sliders 304 are inserted into the internal grooves of the fixed frame 301. Then, the movable limiting block 305 is placed around the movable hollow tube 306. By rotating the movable limiting block 305, the upper and lower protrusions of the movable hollow tube 306 are inserted into the limiting groove on one side of the movable limiting block 305. Then, the movable disc 302 is rotated, which drives the threaded screw 308 to rotate. The internal thread of the movable hollow tube 306 cooperates with the threaded screw 308, so that the movable hollow tube 306 moves left and right within the limiting pipe 307.

[0035] The movable hollow tube 306 drives the movable limiting block 305, thereby clamping and fixing the two fixed blocks 303, thus fixing the two arc-shaped connecting blocks 6 on both sides of the ball valve pipe 9. The arc-shaped connecting blocks 6 drive the connecting strip 5, and the connecting strip 5 drives the heating shell 2. Thus, the heating shell 2 is stably and firmly installed, ensuring that the constant temperature mechanism 8 is in close contact with the ball valve ball 10 and the ball valve pipe 9, making heat conduction more efficient, and improving the stability of the overall structure of the ball valve.

[0036] In order to control the internal temperature of the ball valve ball 10 and the ball valve pipe 9, such as Figure 5 and Figure 6As shown, the constant temperature mechanism 8 includes an arc connecting plate 801, an air outlet 802, a temperature monitor 803, a water inlet 804, a water outlet 805, a baffle 806, and a heating copper tube 807. The air outlet 802 is fixedly connected to the inside of the heating shell 2, the temperature monitor 803 is fixedly connected to the inside of the heating shell 2, and the water inlet 804 is fixedly connected to the inside of the heating shell 2.

[0037] The water outlet 805 is fixedly connected to the bottom of the heating shell 2, and the air outlet 802, water inlet 804 and water outlet 805 pass through the heating shell 2 respectively. Two baffles 806 are fixedly connected to the inside of the heating shell 2 respectively. Two arc connecting plates 801 are fixedly connected to the inner wall of the heating shell 2 respectively. Several heating copper tubes 807 are fixedly connected to the opposite inner sides of the two arc connecting plates 801 respectively. The temperature monitor 803 is model WSS-3011.

[0038] During operation, hot water or other heating media are introduced through the water inlet 804. The media flows inside the heating shell 2 and exchanges heat with the ball valve ball 10 and the ball valve pipe 9. The heating copper tube 807 can further heat the internal media as needed. The temperature monitor 803 monitors the internal temperature in real time and feeds the data back to the controller 1. When the temperature is too high, the controller 1 can control and reduce the heating power of the heating copper tube 807.

[0039] Conversely, when the temperature is too low, heating is increased, and the used heating medium flows out through the outlet hole 805. This can accurately maintain the temperature of the fluid inside the ball valve ball 10 and the ball valve pipe 9, effectively preventing adverse phenomena such as crystallization and solidification of the fluid due to temperature fluctuations, ensuring the normal transport of the fluid in the pipeline, and realizing intelligent temperature regulation, reducing energy consumption and improving energy utilization efficiency.

[0040] Working principle: By rotating the control handwheel 4, the ball valve ball 10 rotates internally, thereby controlling the flow and flow rate of fluid in the ball valve pipeline 9. Two sliders 304 are engaged in the internal grooves of the fixed bracket 301. Then, the movable limit block 305 is fitted around the movable hollow tube 306. Rotating the movable limit block 305 causes the upper and lower protrusions of the movable hollow tube 306 to engage in the limiting groove on one side of the movable limit block 305. Next, rotating the movable disc 302 drives the threaded screw 308. Rotating the hollow tube 306 causes its internal thread to engage with the threaded screw 308, allowing the hollow tube 306 to move left and right within the limiting pipe 307. The hollow tube 306 then moves the movable limiting block 305, which clamps and fixes the two fixed blocks 303, thereby fixing the two arc-shaped connecting blocks 6 on both sides of the ball valve pipe 9. The arc-shaped connecting blocks 6 then move the connecting strip 5, which in turn moves the heating shell 2, thus fixing the thermostatic mechanism 8 on both sides of the ball valve ball 10 and the two ball valve pipes 9.

[0041] Hot water or other heating medium is introduced through the inlet hole 804. The medium flows inside the heating shell 2 and exchanges heat with the ball valve ball 10 and the ball valve pipe 9. The heating copper pipe 807 can further heat the internal medium as needed. The temperature monitor 803 monitors the internal temperature in real time and feeds the data back to the controller 1. When the temperature is too high, the controller 1 can control the reduction of the heating power of the heating copper pipe 807. Conversely, when the temperature is too low, the heating is increased. The used heating medium flows out through the outlet hole 805, thereby controlling the internal temperature of the ball valve pipe 9 and the ball valve ball 10 through heat conduction.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
