Description

Technical Field

[0001] The present invention belongs to the technical field of electric regulating valves, and in particular is a durable electric regulating valve suitable for extreme working conditions. Background Art

[0002] An electric control valve is an automated device used to control fluid flow, pressure and temperature. It uses an electric actuator to adjust the valve opening to achieve precise control of fluid flow. The electric control valve is usually composed of a valve body, a valve seat, a valve core and an electric drive device.

[0003] For example, the utility model with the publication number CN219796155U discloses an electric regulating valve, which belongs to the field of electric regulating valves. The electric regulating valve comprises a valve body, which is a hollow cubic structure with openings on both sides. A valve cover with a tubular structure is vertically installed on the upper surface of the valve body. A valve core is inserted into the interior of the valve cover. One end of the valve core extends into the interior of the valve body, and the other end of the valve core extends out of the interior of the valve body and is provided with an electric actuator. A lubrication cavity with an annular structure is opened on the inner side of the valve cover. A packing layer surrounding the valve core is provided on the lower surface of the lubrication cavity. An oil filling pipe is inserted into the interior of the lubrication cavity. One end of the oil filling pipe extends out of the interior of the valve cover and is provided with an oil supply mechanism. A one-way valve located outside the valve cover is installed on the outer side of the oil filling pipe. It can be realized that a protective layer can be formed on the exposed surface of the valve core with lubricating grease to resist the rust caused by external moisture and air, and the maintenance frequency can be reduced to reduce the maintenance cost of the valve core in the electric regulating valve.

[0004] When the above-mentioned device is in use, the maintenance frequency of the electric control valve is reduced by the cooperation between structures such as the lubrication chamber and the oil filling pipe. However, when the electric control valve is operating under some extreme working conditions, for example, in the steel smelting industry, some electric control valves close to the furnace may be exposed to a high temperature environment of hundreds of degrees, and the electric control valve may need to work at a high load for a long time. At this time, the electric actuator and the mechanical parts inside the valve will generate a large amount of friction heat. At the same time, the high temperature of the environment will also have a huge impact on the material properties of the equipment. When the above-mentioned device is in use, no effective heat dissipation component is set. If the heat cannot be dissipated in time, the temperature of these parts will continue to rise, which may cause metal expansion and aging of sealing materials. It may also affect the performance of electrical components, and then affect the service life and normal operation of the electric control valve. Therefore, a durable electric control valve suitable for extreme working conditions is proposed to solve the problems raised in the background technology. Summary of the invention

[0008] Preferably, the clamping assembly comprises a turntable, the turntable is threadedly connected to the valve core, a slide groove is provided on the top of the turntable, and a square block is movably connected to the inner ring of the slide groove at equal angles.

[0009] Preferably, an inner ring at the top of the valve core is movably connected with an inclined block at equal angles, and both ends of the inclined block are fixedly connected with spring plates, and the inclined block is elastically connected to the execution structure through the spring plates.

[0010] Preferably, one end of the inclined block close to the square block is in an inclined shape, and the other end of the inclined block penetrates the outer wall of the valve core and extends to the outside of the valve core. The inclined block is engaged with the slot in an initial state.

[0011] Preferably, a limiting groove matching with the square block is formed on the inner wall of the valve core, and the top end of the square block abuts against the inclined surface of the inclined block.

[0012] Preferably, two groups of bolt assemblies are symmetrically arranged on the outer wall of the turntable, and the turntable is fixedly connected to the execution structure through the bolt assemblies.

[0013] Preferably, the bottom end of the support ring penetrates the outer wall of the valve core and extends to the outside of the valve core, and the turntable abuts against the bottom of the support ring.

[0014] Preferably, the sealing ring is made of rubber material, and the top of the sealing ring abuts against the bottom of the execution structure.

[0015] Preferably, one end of the first cooling pipe is connected to the second cooling pipe, and the other end of the first cooling pipe is connected to the input end of the water pump. The first cooling pipe is in a snake shape, thereby extending the flow path of the coolant inside the first cooling pipe.

[0016] Preferably, the second cooling tube is in a threaded shape, the second cooling tube surrounds the inner wall of the valve core, and the bottom end of the heat dissipation fin is connected to the outside.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention cooperates between structures such as the outer box, the water pump and the heat dissipation component, so as to facilitate the heat dissipation of the electric control valve under extreme working conditions. The second cooling pipe is surrounded by the inner wall of the valve core, so that when the water pump drives the coolant to flow in the second cooling pipe, the coolant can better absorb the heat inside the valve core.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, the present invention provides a durable electric regulating valve suitable for extreme working conditions, including a valve core 1 and an execution structure 2, the valve core 1 is movably connected to a valve body 3, the bottom of the valve core 1 is fixedly connected to an outer box 4, a water pump 5 and a heat dissipation component 6 are arranged inside the outer box 4, a clamping component 7 is arranged on the top of the valve core 1, a support ring 8 is movably connected to the top of the valve core 1, a sealing ring 9 is fixedly connected inside the support ring 8, a clamping groove 11 is provided at the bottom end of the execution structure 2, and a temperature sensor 12 is fixedly connected inside the valve core 1;

[0029] The heat dissipation assembly 6 includes a heat dissipation box 61 , two fans 62 are fixedly connected to the top of the inner cavity of the heat dissipation box 61 , a first cooling pipe 63 and heat dissipation fins 64 are arranged inside the heat dissipation box 61 , and a second cooling pipe 65 is fixedly connected to the output end of the water pump 5 .

[0030] The above scheme is adopted: the second cooling pipe 65 is surrounded by the inner wall of the valve core 1, so that when the water pump 5 drives the coolant to flow in the second cooling pipe 65, the coolant can better absorb the heat inside the valve core 1, and through the design of the fan 62 and the heat dissipation fins 64, the coolant can flow into the first cooling pipe 63 through the second cooling pipe 65. When flowing through the first cooling pipe 63, the heat can be transferred to the inner wall of the heat dissipation box 61 and the heat dissipation fins 64, and the fan 62 rotates, thereby driving the air to pass through the heat dissipation fins 64, and then taking away the heat on the heat dissipation fins 64, so that the temperature of the heat dissipation fins 64 and the coolant is reduced together, thereby facilitating the heat dissipation of the electric control valve under extreme working conditions, thereby ensuring the normal operation of the device.

[0031] like Figure 4 and Figure 6As shown, the clamping assembly 7 includes a turntable 71, which is threadedly connected to the valve core 1, and a slide groove 72 is provided on the top of the turntable 71. The inner ring of the slide groove 72 is movably connected with a square block 73 at an equal angle. The inner ring of the top of the valve core 1 is movably connected with an inclined block 74 at an equal angle. Both ends of the inclined block 74 are fixedly connected with spring pieces 75. The inclined block 74 is elastically connected to the execution structure 2 through the spring pieces 75. The end of the inclined block 74 close to the square block 73 is in a slope shape, and the other end of the inclined block 74 passes through the outer wall of the valve core 1 and extends to the outside of the valve core 1. The inclined block 74 is clamped with the clamping groove 11 in the initial state.

[0032] The above scheme is adopted: through the cooperation between the structures such as the clamping assembly 7, the sealing ring 9 and the clamping groove 11, it is convenient to disassemble and maintain the electric control valve, and the rotary disk 71 is threadedly connected with the valve core 1, so that when the rotary disk 71 rotates, the square block 73 can be pulled down through the slide groove 72, so that the inclined block 74 is released from the abutment with one end of the square block 73, and through the design of the spring piece 75, after the inclined block 74 is released from the abutment, it can move in the direction away from the execution structure 2 under the action of the pulling force of the spring piece 75, and then detach from the inside of the clamping groove 11, thereby releasing the fixed connection between the valve core 1 and the execution structure 2, and then facilitating the disassembly and maintenance of the electric control valve, thereby improving the convenience of the overall device;

[0033] One end of the square block 73 is in the shape of an inclined surface. Its function is that when the valve core 1 and the execution structure 2 need to be installed, at this time, the operator inserts the bottom end of the execution structure 2 into the valve core 1, and then rotates the turntable 71 to drive the square block 73 to move upward through the slide groove 72, so that the top of the square block 73 abuts against the inclined surface of the inclined block 74, so that the upward force is converted into a horizontal force through the inclined surface, and the inclined block 74 moves toward the execution structure 2 under the squeezing of the square block 73, thereby driving the inclined block 74 to be re-inserted into the interior of the card slot 11, so as to facilitate the fixed installation of the valve core 1 and the execution structure 2.

[0034] like Figure 4 and Figure 6 As shown, the inner wall of the valve core 1 is provided with a limiting groove that matches the square block 73, the top of the square block 73 abuts against the inclined surface of the inclined block 74, the outer wall of the turntable 71 is symmetrically provided with two groups of bolt assemblies 10, the turntable 71 is fixedly connected to the execution structure 2 through the bolt assemblies 10, the bottom end of the support ring 8 passes through the outer wall of the valve core 1 and extends to the outside of the valve core 1, the turntable 71 abuts against the bottom of the support ring 8, the sealing ring 9 is made of rubber material, and the top of the sealing ring 9 abuts against the bottom of the execution structure 2.

[0035] The above solution is adopted: a limit groove is provided on the inner wall of the valve core 1, and its function is that the limit groove is used to limit the circumferential position of the square block 73 in the vertical direction. Figure 4 and Figure 6It can be seen that a slider movable in the slide groove 72 is provided at the bottom of the square block 73. When the turntable 71 rotates, the slider at the bottom of the square block 73 slides in the slide groove 72 due to the circumferential limit of the square block 73 by the limit groove, and drives the square block 73 to move downward through the slide groove 72, thereby ensuring the normal operation of the device and ensuring that the position of the square block 73 remains unchanged. After moving upward, it can always abut against the inclined surface of the inclined block 74.

[0036] Through the design of the support ring 8 and the sealing ring 9, its function is that when the turntable 71 moves up, it abuts against the bottom end of the support ring 8, thereby squeezing the support ring 8 and driving the sealing ring 9 inside it to move upward, so that the top of the sealing ring 9 fits with the bottom of the execution structure 2. The sealing ring 9 is made of rubber material, and its function is that since the rubber material has good elasticity, when the sealing ring 9 abuts against the bottom of the execution structure 2, the sealing ring 9 will be deformed by force, so that it fits tightly at the connection between the execution structure 2 and the valve core 1, thereby improving the overall sealing of the device.

[0037] like Figure 2 and Figure 3 , Figure 5 As shown, one end of the first cooling pipe 63 is connected to the second cooling pipe 65, and the other end of the first cooling pipe 63 is connected to the input end of the water pump 5. The first cooling pipe 63 is in a snake shape, and the second cooling pipe 65 is in a threaded shape. The second cooling pipe 65 surrounds the inner wall of the valve core 1, and the bottom end of the heat dissipation fin 64 is connected to the outside.

[0038] The above solution is adopted: the first cooling tube 63 is in a snake shape, and its function is that the snake shape greatly prolongs the flow path of the coolant inside the first cooling tube 63 through its winding shape. Compared with a straight cooling tube, the serpentine tube can allow the coolant to have more time and a larger area for heat exchange in the heat sink 61. The length of the serpentine cooling tube can be several times that of a straight cooling tube, which means that the coolant has more opportunities to transfer the absorbed heat to the heat sink fins 64, thereby improving the heat dissipation efficiency.

[0039] The working principle and use process of the present invention are as follows: when the device runs for a period of time under extreme working conditions, the heat inside the valve core 1 rises. At the same time, the temperature sensor 12 installed in the valve core 1 monitors the temperature of the fluid or components in the valve core 1 in real time. The temperature sensor 12 usually adopts temperature-sensitive elements such as thermistors and thermocouples. Its resistance or voltage will change with the change of temperature. When the temperature changes, the temperature sensor 12 transmits the corresponding resistance or voltage signal to the control system connected thereto, such as PLC, single-chip microcomputer or special temperature controller. After receiving the signal from the temperature sensor 12, the control system processes and analyzes the signal and compares the actual temperature with the preset temperature threshold. When the heat in the valve core 1 reaches the predetermined value, the control system will issue an operating instruction to the water pump. At the same time, the circuit inside the temperature sensor 12 will directly output a high level or low level signal to drive the control circuit of the fan 62, so that the two fans 62 rotate. The above contents belong to the prior art.

[0040] When the water pump 5 is running, the coolant in the second cooling pipe 65 is driven to flow, and the second cooling pipe 65 surrounds the inner wall of the valve core 1, so that the coolant in the second cooling pipe 65 absorbs the heat of the valve core 1 and the surrounding components, thereby reducing the temperature of the valve core 1. The temperature of the coolant that has absorbed the heat increases, and flows along the second cooling pipe 65, and finally flows back to the first cooling pipe 63. When the coolant carrying heat flows through the first cooling pipe 63, the heat quickly diffuses through the pipe wall to the inner wall of the heat dissipation box 61, and then is transferred to the heat dissipation fins 64. Subsequently, the fan 62 rotates, thereby driving air to pass through the heat dissipation fins 64, thereby taking away the heat on the heat dissipation fins 64, so that the temperature of the heat dissipation fins 64 and the coolant is reduced together. After passing through the heat dissipation component 6, the coolant returns to a state suitable for being re-inhaled by the water pump 5, thereby completing a complete reflux heat dissipation circulation system, thereby facilitating the heat dissipation of the electric control valve under extreme conditions;

[0041] When the locking nut 72 is in place, the latch will automatically lock the locking nut 77, which will be used to lock the valve body 70, so that the valve body 70 can be locked immediately.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

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