Description

Technical Field

[0001] This invention relates to the field of valve technology, and more particularly to a high-temperature butterfly valve with water-cooled control. Background Technology

[0002] High-temperature butterfly valves regulate fluid flow by controlling the rotation angle of the butterfly plate. They are often made of high-temperature resistant materials and can maintain stable performance in high-temperature environments, withstanding temperatures of 450℃ or even higher. They are widely used in the metallurgical, chemical, and building materials industries. This article provides technical insights into high-temperature butterfly valves.

[0003] The following problems were discovered in the research on high-temperature butterfly valves:

[0004] High-temperature butterfly valves typically use water flowing inside the valve stem to cool the entire valve. When the valve is closed, fluid cannot be transported through it, so there is no need to cool it with water. In this case, the water supply needs to be manually closed. When the valve is opened, the water supply needs to be manually opened again. This prevents the valve from cooling the water supply during the opening and closing of the valve plate, thus eliminating the need for manual control and allowing water to quickly enter the valve.

[0005] Currently, the prior art disclosure number CN112664665B discloses a high-temperature resistant self-cleaning high-temperature butterfly valve. This invention adopts a water-cooling and compression-type air-cooling cooling structure, which not only improves the high-temperature resistance of the high-temperature butterfly valve, but also improves its service life and cooling effect. Secondly, it adopts a compression-type combined vibration reduction structure, which not only improves the vibration resistance of the high-temperature butterfly valve, but also improves its durability.

[0006] This invention primarily solves the problem that high-temperature butterfly valves cannot achieve water-cooled control of the clean water end during the opening and closing process of the butterfly plate, thus enabling clean water to quickly enter the high-temperature butterfly valve without manual control. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides a high-temperature butterfly valve with water-cooled control to solve the problems described in the background art.

[0008] The purpose and effectiveness of the water-cooled high-temperature butterfly valve of this invention are achieved through the following specific technical means:

[0009] A water-cooled high-temperature butterfly valve includes a valve body, a handle rotatably connected to the upper end of the valve body, a connecting frame rotatably connected to the lower end of the handle, a valve stem rotatably connected to the lower end of the connecting frame, and butterfly plates connecting through the two sides of the valve stem.

[0010] Furthermore, the valve body is installed and fixed to the pipeline via a flange, and a cooling chamber is provided on the outer side of the valve body. The cooling chamber is annular, and the upper end of the cooling chamber is perpendicular to the upper end of the valve stem. A drain outlet is provided at the lower end of the cooling chamber.

[0011] Furthermore, the lower end of the connecting frame is octagonal in shape, and a groove is provided at the lower end of the connecting frame.

[0012] Furthermore, the butterfly plate rotates 90° inside the valve body via the valve stem, the valve stem is hollow inside, and there are openings through the valve stem on both sides near the butterfly plate.

[0013] Furthermore, the butterfly plate has a through hole inside, which is arc-shaped and extends through the end of the butterfly plate near the valve stem, allowing the butterfly plate to be connected to the valve stem through the hole.

[0014] Furthermore, the lower end of the valve stem is connected to an inner cylinder, and an inner cavity is opened inside the valve body near the lower end of the inner cylinder. A connecting pipe is connected through the lower end of the inner cavity of the valve body, and the inner cylinder is connected to the connecting pipe in a perpendicular direction through the inner cavity.

[0015] Furthermore, the connecting pipe extends through the lower end of the valve body and connects to the water pipe, allowing clean water to enter the inner cylinder and valve stem through the connecting pipe.

[0016] Furthermore, the inner wall of the inner cylinder is surrounded by a gasket ring, the lower end of the inner cylinder is rotatably connected to a rotating ring, the lower end of the rotating ring is surrounded by a sealing bag, and the inner cavity at the lower end of the valve body is surrounded by a fixing ring, the upper end of the fixing ring being connected to the lower end of the sealing bag.

[0017] Furthermore, the rotating ring, sealing bag, and fixing ring are arranged vertically in sequence, and when the butterfly plate is in the open state inside the valve body, the sealing bag is cylindrical in shape.

[0018] Furthermore, the thickness of the sealing bag is 0.4-1cm, the fixing ring is circular, and the fixing ring is stationary when the rotating ring rotates 90° in the horizontal direction.

[0019] Furthermore, a pull rope is embedded in the inner side of the groove at the lower end of the connecting frame, and a base is provided at the lower end of the pull rope. A rotating ball is hinged to the lower end of the base, and the swinging of the rotating ball is connected to a blade.

[0020] Furthermore, when the chassis is inside the inner cylinder, the pull rope passes through the inside of the valve stem.

[0021] Furthermore, the blade is tilted vertically and oscillates by a rotating ball, with an oscillation angle of 15-60°.

[0022] Furthermore, the lower end of the blade slides and abuts against the upper end of the inner cylinder's gasket in a vertical direction. The blade is matched with the rotating ball, and the blade is arc-shaped with an arc angle of 90°. The blade surrounds the lower end of the chassis, and the overall combination of the blades forms a conical shape.

[0023] Furthermore, a bearing is hinged to the lower end of the inner wall of the butterfly plate hole, and a baffle is oscillatingly connected to one side of the bearing.

[0024] Furthermore, the baffle is arc-shaped with an arc angle of 90-120°, and the baffle tilts and swings vertically via a bearing.

[0025] Beneficial effects:

[0026] 1. When the butterfly plate is in the open position inside the valve body, the sealing bag is cylindrical in shape. At this time, clean water can enter the inner cavity at the lower end of the valve body through the connecting pipe, which facilitates the entry of clean water into the valve stem.

[0027] When the valve stem drives the butterfly plate to rotate 90°, the butterfly plate forms a closed rotation with respect to the inside of the valve body. The valve stem synchronously drives the inner cylinder to rotate. The inner cylinder drives the upper end of the sealing bag to rotate 90° through the rotating ring. The lower end of the sealing bag is stationary above the fixed ring. At this time, the sealing bag is twisted as a whole, and the sealing bag can form a closed state with respect to the inside of the valve body.

[0028] 2. When the butterfly plate inside the valve body is in the open state, the sealing bag is cylindrical. Clean water impacts the blade and the lower end of the base through the inner cylinder. Due to the impact of the clean water, the base and pull rope are stored in the groove at the lower end of the connecting frame. The blade is tilted vertically by the rotating ball and stored without affecting the normal flow of clean water inside the valve stem.

[0029] 3. When the butterfly plate inside the valve body is in a closed state, the sealing bag twists as a whole, forming a seal on the bottom of the inner cylinder. Water cannot impact the lower end of the chassis. Using the weight of the chassis and blades, the chassis and blades fall downwards via the pull rope. During the downward fall, the air creates resistance on the lower end of the blades, causing the blades to swing at an angle via the rotating ball. The lower end of the blades is perpendicular to the upper end of the gasket, allowing the blades to form a further seal on the inside of the inner cylinder. This enables the blades to achieve water-cooled control during the opening and closing of the butterfly plate. After the butterfly plate is closed, the blades and the sealing bag form a double seal above the connecting pipe. After the butterfly plate is opened, water quickly enters the valve stem through the connecting pipe, eliminating the need for manual operation of the connecting pipe to open and close.

[0030] 4. After the clean water enters the lower end of the butterfly plate's hole, the clean water impacts one end of the baffle, and the baffle swings at an angle through the bearing, and the baffle adheres to the inner wall of the butterfly plate;

[0031] When clean water enters through the upper part of the butterfly plate's orifice, it impacts the upper part of the baffle. The baffle swings downwards via the bearing, thus sealing off the orifice of the butterfly plate. This prevents clean water from flowing back to the lower part of the valve stem, thereby controlling the flow of clean water inside the butterfly plate and preventing the upper part of the valve stem from flowing back into the butterfly plate.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0045] As attached Figure 1 To be continued Figure 10 As shown:

[0046] Example 1: A high-temperature butterfly valve with water cooling control includes a valve body 1, a handle 101 rotatably connected to the upper end of the valve body 1, a connecting frame 2 rotatably connected to the lower end of the handle 101, a valve stem 103 rotatably connected to the lower end of the connecting frame 2, and butterfly plates 102 connecting through both sides of the valve stem 103.

[0047] The valve body 1 is installed and fixed to the pipeline via a flange. A cooling chamber is provided on the outer side of the valve body 1. The cooling chamber is annular, and its upper end is perpendicular to the upper end of the valve stem 103. A drain port is provided at the lower end of the cooling chamber. Please refer to the attached instruction manual. Figure 4 As shown;

[0048] The lower end of the connecting bracket 2 is octagonal in shape, and a groove is provided at the lower end of the connecting bracket 2. Please refer to the instruction manual for details. Figure 7 As shown;

[0049] The lower end of the connecting bracket 2 is arranged in an octagonal shape, and the lower end of the connecting bracket 2 and the upper end of the valve stem 103 are provided with an opening, through which the clean water inside the valve stem 103 can easily enter the cooling chamber of the valve body 1.

[0050] The butterfly plate 102 rotates 90° inside the valve body 1 via the valve stem 103. The valve stem 103 is hollow inside, with openings on both sides near the butterfly plate 102. Please refer to the instruction manual for details. Figure 3 As shown;

[0051] The butterfly plate 102 has a through hole in the inside. The hole is arc-shaped and passes through the end of the butterfly plate 102 near the valve stem 103. The butterfly plate 102 is connected to the valve stem 103 through the hole.

[0052] The lower end of the valve stem 103 is connected to the inner cylinder 3. The valve body 1 has an inner cavity near the lower end of the inner cylinder 3. The lower end of the inner cavity of the valve body 1 is connected to the connecting pipe 104. The inner cylinder 3 is connected to the connecting pipe 104 in a perpendicular direction through the inner cavity.

[0053] The connecting pipe 104 extends through the lower end of the valve body 1 and is connected to the water pipe. Clean water enters the inner cylinder 3 and the valve stem 103 through the connecting pipe 104.

[0054] Wherein: the valve body 1 is installed and fixed to the pipeline by flange. The handle 101 is rotated manually or by a drive device. The handle 101 rotates the valve stem 103 through the connecting frame 2. The valve stem 103 rotates the butterfly plate 102 at 90°. When the valve stem 103 rotates, the inner cylinder 3 rotates synchronously. The rotation of the butterfly plate 102 forms a seal and opening inside the valve body 1.

[0055] The connecting pipe 104 is connected to the water pipe. Clean water enters the inner cylinder 3 through the connecting pipe 104 and then enters the valve stem 103. Since there is a hole through the inside of the butterfly plate 102, and the hole is arc-shaped, the hole is located at the end of the butterfly plate 102 near the valve stem 103. Therefore, the clean water can easily flow in an arc shape inside the butterfly plate 102 through the openings on both sides of the valve stem 103. The clean water then enters the upper part of the valve stem 103 and enters the cooling chamber of the valve body 1 through the valve stem 103. Then it is discharged through the drain port at the lower end of the cooling chamber, so that the butterfly plate 102, valve stem 103 and valve body 1 of this high temperature butterfly valve can form a water cooling circulation for cooling.

[0056] Example 2: Refer to the attached instruction manual Figure 4-10 It can be seen that the inner wall of the inner cylinder 3 is surrounded by a gasket 301, the lower end of the inner cylinder 3 is rotatably connected to a rotating ring 302, the lower end of the rotating ring 302 is surrounded by a sealing bag 303, the inner cavity of the lower end of the valve body 1 is surrounded by a fixing ring 4, and the upper end of the fixing ring 4 is connected to the lower end of the sealing bag 303.

[0057] The rotating ring 302, sealing bag 303, and fixing ring 4 are arranged vertically in sequence. When the butterfly plate 102 is in the open state inside the valve body 1, the sealing bag 303 is cylindrical in shape. (Refer to the instruction manual for details.) Figure 6 As shown;

[0058] The 303 sealed bag is made of silicone nitrile rubber, which can maintain structural stability and not decompose within the range of 430℃-480℃;

[0059] The thickness of the sealing bag 303 is 0.4-1cm. The fixing ring 4 is circular. When the rotating ring 302 rotates 90° in the horizontal direction, the fixing ring 4 is stationary.

[0060] When the butterfly plate 102 is in the open state inside the valve body 1, the sealing bag 303 is cylindrical in shape. At this time, clean water can enter the inner cavity at the lower end of the valve body 1 through the connecting pipe 104, which facilitates the entry of clean water into the valve stem 103.

[0061] When the valve stem 103 drives the butterfly plate 102 to rotate 90°, the butterfly plate 102 forms a closed rotation around the inside of the valve body 1. Simultaneously, the valve stem 103 drives the inner cylinder 3 to rotate. The inner cylinder 3, through the rotating ring 302, drives the upper end of the sealing bag 303 to rotate 90°. The lower end of the sealing bag 303 is stationary above the fixed ring 4. At this time, the sealing bag 303 is in a twisted state, and the sealing bag 303 can form a closed state around the inner cavity of the valve body 1. (Refer to the attached instruction manual for details.) Figure 5 As shown;

[0062] Example 3: Refer to the attached instruction manual Figure 4-7 It can be seen that a pull rope 201 is inlaid in the inner side of the groove at the lower end of the connecting frame 2, and a base plate 202 is provided at the lower end of the pull rope 201. A rotating ball 203 is hinged at the lower end of the base plate 202, and a blade 204 is connected to the swing of the rotating ball 203.

[0063] The drawstring 201 is made of the same material as the sealing bag 303, both of which are made of silicone nitride rubber and can withstand high temperatures.

[0064] When the chassis 202 is inside the inner cylinder 3, the pull rope 201 passes through the inside of the valve stem 103. Please refer to the instruction manual appendix. Figure 7 As shown;

[0065] The blade 204 tilts vertically via the rotating ball 203, with an angle of 15-60°.

[0066] The lower end of blade 204 slides and abuts against the upper end of the gasket 301 of the inner cylinder 3 in a vertical direction. Blade 204 is matched with rotating ball 203. Blade 204 is arc-shaped with an arc angle of 90°. Blade 204 surrounds the lower end of chassis 202. The overall assembly of blade 204 is conical. Please refer to the instruction manual. Figure 10 As shown;

[0067] The blade 204 is assembled in a conical shape. When the blade 204 is located at the upper end of the gasket 301 of the inner cylinder 3, the shape of the blade 204 can form a seal inside the inner cylinder 3.

[0068] Specifically: When the butterfly plate 102 inside the valve body 1 is in the open state, the sealing bag 303 is cylindrical. Clean water flows through the inner cylinder 3 and impacts the blade 204 and the lower end of the base 202. Due to the impact of the clean water, the base 202 and the pull rope 201 are retracted into the groove at the lower end of the connecting frame 2. The blade 204 is tilted vertically by the rotating ball 203, which does not affect the normal flow of clean water inside the valve stem 103. Please refer to the attached instruction manual. Figure 6 As shown;

[0069] When the butterfly plate 102 inside the valve body 1 is in a closed state, in conjunction with embodiment 2, the sealing bag 303 is twisted as a whole, forming a seal on the lower part of the inner cylinder 3. The water cannot impact the lower end of the chassis 202. Using the weight of the chassis 202 and the blade 204, the chassis 202 and the blade 204 fall downwards through the pull rope 201. The air generates resistance on the lower end of the blade 204 during the downward fall. The blade 204 swings at an angle through the rotating ball 203. The lower end of the blade 204 is perpendicular to the upper end of the gasket 301. The blade 204 can further seal the inside of the inner cylinder 3, so that the blade 204 can form water cooling control during the opening and closing of the butterfly plate 102. After the butterfly plate 102 is closed, the blade 204 and the sealing bag 303 form a double seal on the upper part of the connecting pipe 104. After the butterfly plate 102 is opened, the water quickly enters the inside of the valve stem 103 through the connecting pipe 104, without the need for manual opening and closing of the connecting pipe 104.

[0070] Example 4: Refer to the appendix of the instruction manual Figure 6 and 7 It can be seen that the lower end of the inner wall of the butterfly plate 102 hole is hinged with a bearing 5, and a baffle 501 is oscillatingly connected to one side of the bearing 5.

[0071] The baffle 501 is arc-shaped with an arc angle of 90-120°. The baffle 501 tilts and swings vertically through the bearing 5.

[0072] Specifically: After clean water enters the lower end of the hole in the butterfly plate 102, the water impacts one end of the baffle 501. The baffle 501 tilts and swings via the bearing 5, and the baffle 501 adheres to the inner wall of the butterfly plate 102. (Refer to the instruction manual for details.) Figure 6 As shown;

[0073] When clean water enters through the upper end of the orifice of the butterfly plate 102, it impacts the upper end of the baffle 501. The baffle 501 swings downward via the bearing 5, thus sealing the orifice of the butterfly plate 102 and preventing clean water from flowing back to the lower end of the valve stem 103. This controls the flow of clean water inside the butterfly plate 102 and prevents the upper part of the valve stem 103 from flowing back into the butterfly plate 102. (Refer to the instruction manual for details.) Figure 7 As shown.
