Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a heat dissipation ball valve for high-temperature environments. Background Technology

[0002] A ball valve is a valve that uses a ball with a circular channel as its opening and closing element. The ball rotates with the valve stem to achieve the opening and closing action. The main components of a ball valve include the ball, valve seat, valve stem, and handle. When the handle is rotated, the valve stem drives the ball to rotate, thereby changing the shape of the channel inside the valve body and realizing the flow control of fluid.

[0003] High-temperature ball valves are specially designed valves that can operate normally in high-temperature environments. They are commonly used in high-temperature fluid control systems in industries such as petroleum, chemical, metallurgy, and power. These ball valves have excellent high-temperature resistance, corrosion resistance, and mechanical strength, which can meet the needs of different working conditions.

[0004] The prior art patent document CN213808980U discloses a high-temperature resistant ball valve. This high-temperature resistant ball valve is equipped with a protective pad to make the valve ball more wear-resistant and resistant to high temperatures during long-term use. It uses rolling balls to make the valve ball surface contact with the rolling balls, changing the traditional sliding friction to rolling friction, which helps to reduce friction and prevents jamming, making it easier to rotate the valve stem. It is equipped with multiple sealing structures to improve the sealing performance of the ball valve, making it less prone to water leakage and beneficial to the long-term use of the valve body. It is equipped with a filter screen to prevent impurities from entering the valve body, which helps to protect the valve body and extend its service life.

[0005] Although the aforementioned prior art replaces traditional sliding friction with rolling friction in its high-temperature resistant ball valve, which helps reduce friction and makes it less prone to jamming, thus requiring less effort to rotate the valve stem, the ball valve in this patented technology has a problem: during use, the high-temperature liquid flowing through the pipe comes into contact with the ball, and the heat is transferred upwards along the valve stem. This heat then affects the equipment at the top that drives the ball valve, shortening its service life. Therefore, we need a heat-dissipating ball valve for high-temperature environments. Utility Model Content

[0006] The purpose of this utility model is to provide a heat-dissipating ball valve for high-temperature environments, in order to solve the problem in the ball valve of the patented technology mentioned in the background art that, during use, high-temperature liquid flows through the pipe and comes into contact with the ball, and the heat is transferred upward along the valve stem, which in turn affects the equipment at the top used to drive the ball valve and shortens the service life of the ball valve.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A heat-dissipating ball valve for high-temperature environments includes a valve body, a valve stem mounted on the top of the valve body, a fixed box provided on the top of the valve stem, a heat dissipation component mounted on one side of the fixed box, an equipment box fixedly connected to the top of the valve stem, and a drive component provided inside the equipment box.

[0009] The heat dissipation assembly includes a first flange, a heat insulation pad is installed on one side of the first flange, and a second flange is provided on one side of the heat insulation pad. A fixing bolt is threaded to one side of the second flange, and an exhaust fan is installed on one side of the second flange. The top of the fixed box is provided with an installation groove, and a dustproof net is snapped onto the inner wall of the installation groove.

[0010] The drive assembly includes a motor, the output end of which is detachably connected to a rotating rod via a coupling, and one end of the rotating rod is fixedly connected to a turntable. A toggle lever is fixedly connected to one side of the turntable. A triangular block is installed inside the equipment box, and a slot is provided on one side of the triangular block.

[0011] Preferably, a connecting pipe is fixedly connected to one side of the valve body.

[0012] Preferably, the first flange and the second flange form a fixed structure through a heat insulation gasket, and the heat insulation gasket is disposed between the first flange and the second flange.

[0013] Preferably, one end of the fixing bolt passes through the first flange, the heat insulation gasket, and the second flange simultaneously, and there are multiple fixing bolts.

[0014] Preferably, the fixing box forms an engaging structure with the dustproof net through the mounting groove, and the shape and size of the mounting groove match the shape and size of the dustproof net.

[0015] Preferably, the motor forms a rotating structure with the turntable via a rotating rod, and the rotating rod is positioned between the motor and the turntable.

[0016] Preferably, the turntable forms a rotating structure with a toggle lever and a triangular block, and the shape and size of the toggle lever match the shape and size of the slot.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this heat-dissipating ball valve for high-temperature environments...

[0018] Firstly, this utility model includes a first flange, a heat insulation gasket, a second flange, fixing bolts, an exhaust fan, a mounting groove, and a dustproof net. The exhaust fan, located on one side of the fixed box, draws away the heat from the valve core inside the valve stem, reducing the upward transfer of heat from the valve core. The heat insulation gasket, placed between the first and second flanges, prevents heat transfer to the exhaust fan and its operation. Furthermore, the dustproof net on the other side of the fixed box reduces dust entry into the box, preventing it from affecting the valve core. This, in turn, reduces the temperature inside the valve stem, preventing heat from being transferred upwards to the equipment inside the top equipment box and thus extending the service life of the ball valve.

[0019] Secondly, this utility model is equipped with a motor, a rotating rod, a turntable, a toggle lever, a triangular block, and a slot. By starting the motor, the rotating rod can be driven to rotate, which in turn drives the turntable to rotate. The toggle lever on the turntable can be inserted into the slot on one side of the triangular block, thereby rotating the triangular block. The turntable and the triangular block are set close to each other with a certain gap, so that the two do not come into contact. While controlling the start of the ball valve, the non-contact control also reduces the impact of heat on the equipment. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat dissipation ball valve for high-temperature environments includes a valve body 1, a valve stem 2 mounted on the top of the valve body 1, a fixed box 3 provided on the top of the valve stem 2, a heat dissipation component 4 mounted on one side of the fixed box 3, an equipment box 5 fixedly connected to the top of the valve stem 2, and a drive component 7 provided inside the equipment box 5.

[0027] The heat dissipation assembly 4 includes a first flange 401, a heat insulation pad 402 is installed on one side of the first flange 401, and a second flange 403 is provided on one side of the heat insulation pad 402. A fixing bolt 404 is threadedly connected to one side of the second flange 403, and an exhaust fan 405 is installed on one side of the second flange 403. The top of the fixed box 3 is provided with an installation groove 406, and a dustproof net 407 is snapped onto the inner wall of the installation groove 406.

[0028] The drive assembly 7 includes a motor 701. The output end of the motor 701 is detachably connected to a rotating rod 702 via a coupling. One end of the rotating rod 702 is fixedly connected to a turntable 703. A toggle lever 704 is fixedly connected to one side of the turntable 703. A triangular block 705 is installed inside the equipment box 5. A slot 706 is provided on one side of the triangular block 705.

[0029] Through the above technical solution, the exhaust fan 405 installed on one side of the fixed box 3 can draw away the temperature of the valve core inside the valve stem 2, thereby reducing the upward transmission of the valve core temperature. Furthermore, the heat insulation pad 402 is installed between the first flange 401 and the second flange 403 to prevent heat transfer to the exhaust fan 405 and its operation from being affected. Additionally, the dustproof net 407 installed on the other side of the fixed box 3 can reduce dust entering the fixed box 3, thus preventing it from affecting the valve core. This achieves the effect of reducing the temperature inside the valve stem 2, preventing heat from being transferred upwards to the equipment inside the top equipment box 5 and affecting its operation, thereby improving the service life of the ball valve.

[0030] Specifically, a connecting pipe 6 is fixedly connected to one side of the valve body 1.

[0031] The above technical solution facilitates the connection of the connecting pipes 6 on both sides of the ball valve to other pipes, making it easier to transport liquids.

[0032] Specifically, the first flange 401 is fixed to the second flange 403 by means of a heat insulation gasket 402, and the heat insulation gasket 402 is disposed between the first flange 401 and the second flange 403.

[0033] The above technical solution facilitates the sandwiching of the heat insulation pad 402 between the first flange 401 and the second flange 403, enabling the heat insulation pad 402 to have a certain heat insulation effect, reducing heat transfer to the second flange 403, and achieving the heat insulation effect.

[0034] Specifically, one end of the fixing bolt 404 is set to pass through the first flange 401, the heat insulation gasket 402 and the second flange 403 simultaneously, and there are multiple fixing bolts 404.

[0035] The above technical solution facilitates the installation and fixing of the fixing bolt 404 through the first flange 401, the heat insulation pad 402 and the second flange 403, and also makes it easy to disassemble and replace the heat insulation pad 402 in the future. At the same time, it allows the exhaust fan 405 to be installed on one side of the fixed box 3. When the exhaust fan 405 is started, the heat on the valve core in the fixed box 3 can be extracted and discharged, thereby reducing the heat on the valve core.

[0036] Specifically, the fixed box 3 forms an engaging structure with the dustproof net 407 through the mounting groove 406, and the shape and size of the mounting groove 406 match the shape and size of the dustproof net 407.

[0037] The above technical solution facilitates the installation of the dustproof net 407 by inserting its bottom into the mounting groove 406 and installing it with the fixed box 3. This allows the dustproof net 407 to prevent dust from entering the fixed box 3 and contaminating the valve core, thus reducing the impact on the valve core.

[0038] Specifically, the motor 701 forms a rotating structure with the turntable 703 via the rotating rod 702, and the rotating rod 702 is located between the motor 701 and the turntable 703.

[0039] The above technical solution facilitates the starting motor 701 to drive the rotating rod 702 to rotate while simultaneously driving the turntable 703 to rotate, which in turn drives the actuating rod 704 on the turntable 703 to rotate, thus achieving the effect of rotating the actuating rod 704.

[0040] Specifically, the turntable 703 forms a rotating structure with the toggle lever 704 and the triangular block 705, and the shape and size of the toggle lever 704 match the shape and size of the slot 706.

[0041] The above technical solution facilitates the insertion of the lever 704 into the slot 706 on one side of the triangular block 705 during rotation. The rotational force causes the triangular block 705 to rotate, and the bottom of the triangular block 705 connects with the valve core, thereby causing the triangular block 705 to drive the valve core to rotate, which in turn controls the operation of the ball inside the ball valve, achieving the effect of automatically controlling the flow of the ball valve. Furthermore, the turntable 703 and the triangular block 705 are set close to each other with a certain gap, which not only controls the start of the ball valve but also reduces the impact of heat on the equipment through non-contact control.

[0042] Working Principle: When using this high-temperature environment heat dissipation ball valve, firstly, connect the second flange 403, heat insulation gasket 402, and first flange 401 with fixing bolts 404, so that the exhaust fan 405 on the second flange 403 is installed on one side of the fixed box 3. Then, insert the bottom of the dustproof net 407 into the mounting groove 406 for installation. Start the exhaust fan 405, which can draw heat from the valve core and discharge the heat outward. The heat insulation gasket 402 can isolate the heat to a certain extent, reducing the impact of heat on the exhaust fan 405. The dustproof net 407 reduces the amount of dust entering the fixed box 3. The motor 701 is started, which drives the rotating rod 702 to rotate. The rotating rod 702 drives the turntable 703 to rotate, and the turntable 703 drives the actuating rod 704 to rotate. The actuating rod 704 then extends into the slot 706 on one side of the triangular block 705, causing the triangular block 705 to rotate. This causes the valve core at the bottom of the triangular block 705 to rotate, thus controlling the ball valve. This completes the entire operation. Content not described in detail in this specification is prior art known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
