Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to an intelligent valve based on the Internet of Things. Background Art

[0002] In the water conservancy and hydropower industry, hundreds of valves of various forms are needed. Valves are pipeline accessories used to open and close pipelines and control flow direction. Valves are directly connected to pipelines and installed. During the use of traditional valves, it is difficult to control the flow rate of the fluid inside the valve when it is flowing. The internal space of the valve body is more complicated than that of the pipeline, and it is easy to produce a high pressure drop effect, which causes impact and vibration to the inside of the valve body and reduces the service life of the valve.

[0003] An intelligent valve based on the Internet of Things with application publication number CN111022748A includes a valve body, a valve stem and a handwheel, the handwheel is connected to a lock, the lock includes a mounting platform connected to the valve body and arranged directly above the handwheel, a rotary drive motor is provided on the mounting platform, the rotary drive motor is downwardly connected to a turntable, a lower surface of the turntable is provided with a plurality of telescopic rods evenly distributed along the circumference, the telescopic rods are connected to the telescopic drive motor, the lock also includes a plurality of keyhole rings evenly distributed on the outer edge of the handwheel, and a plurality of telescopic rods are correspondingly inserted into the keyhole rings; an upwardly extending rotating shaft is provided at the center of the upper surface of the turntable, and the rotating shaft is connected to the output shaft of the rotary drive motor via a coupling; the keyhole ring is welded to the outer edge of the handwheel, and the center line of the eyelet of the keyhole ring is kept in the vertical direction after connection.

[0004] Existing technical solutions usually use valves to adjust the overall flow rate inside the pipeline. When the fluid flows inside the valve, the channels inside the valve are relatively complex, resulting in changes in the flow rate after the fluid enters the internal channels of the valve. Existing technical solutions cannot individually control the fluid velocity inside the valve, resulting in the fluid easily experiencing a high pressure drop effect inside the valve. The high pressure drop effect will cause the fluid to generate eddies and turbulence inside the valve. The eddies and turbulence will increase the scouring effect on the valve body, valve seat and ball, causing greater wear and cavitation damage to the surface materials. At the same time, the eddies and turbulence will generate vibrations, causing fasteners and seals to loosen or break, thereby affecting the stability and sealing performance of the valve.

DETAILED DESCRIPTION

[0017] 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.

[0018] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: an intelligent valve based on the Internet of Things, including a valve assembly 2, the valve assembly 2 includes a valve body 202, and also includes a variable diameter assembly 1, the variable diameter assembly 1 includes a fixed ring plate 102, a mounting cylinder 103, a plurality of adjustment blocks 111 and a plurality of rubber blocks 108, the mounting cylinder 103 is fixed above the valve body 202, the mounting cylinder 103 is internally rotatably provided with a gear plate 106, the gear plate 106 is provided with a plurality of arc grooves 107 evenly distributed around the circumference, the arc groove 107 is internally slidably provided with a connecting cylinder 110 and a rubber sleeve 112, the plurality of adjustment blocks 111 and the plurality of rubber blocks 108 are evenly distributed on the circumference of the gear plate 106, and the arc groove 107 is internally slidably provided with a connecting cylinder 110 and a rubber sleeve 112, and the plurality of adjustment blocks 111 and the plurality of rubber blocks 108 are evenly distributed on the circumference of the gear plate 106. A connecting hole 113 is provided, a guide block 109 is fixed on the uppermost adjusting block 111, a fixed ring plate 102 is provided on the valve body 202, the fixed ring plate 102 is fixedly connected to the mounting tube 103 by bolts, a plurality of sliding grooves 105 evenly distributed around the circumference are provided on the fixed ring plate 102, the guide block 109 is slidably provided on the sliding groove 105, a rotating motor 101 is fixed on the fixed ring plate 102, a driving gear 104 is fixed on the output shaft of the rotating motor 101, the driving gear 104 is meshed with the gear plate 106, a power assembly 3 and a buffer assembly 4 are provided on the valve body 202, and a rectifier assembly 5 is provided inside the valve body 202.

[0019] It should be noted that the rubber block 108 and the rubber sleeve 112 are both made of nitrile rubber, so they have excellent oil resistance, wear resistance, heat resistance and physical and mechanical properties. The connecting hole 113 provides an installation position for the connecting cylinder 110 and the rubber sleeve 112. The rotating motor 101 drives the driving gear 104 to rotate through the output shaft, and the driving gear 104 drives the gear plate 106 to rotate. The gear plate 106 drives the arc groove 107 to move, and the arc groove 107 drives the adjustment block 111 and several rubber blocks 108 to move to control the internal aperture size. When the internal aperture becomes smaller, the continuity principle is used. Formula, when the fluid in the pipeline enters the internal aperture, the flow rate increases. After the fluid enters the valve through the adjustable reducer, the flow rate decreases. It is calculated by the formula Q=A1×V1=A2×V2, where Q is the flow rate, A1 and A2 are the areas of two different cross-sections, V1 and V2 are the flow rates of the corresponding cross-sections, and when the flow rate remains constant, the flow rate is inversely proportional to the cross-sectional area. Therefore, when the fluid enters the internal aperture (small cross-section) from the pipeline (large cross-section), the flow rate will increase; conversely, when the fluid enters the valve body 202 from the capillary, the flow rate will decrease. Secondly, the formula of Bernoulli's law is: P1+1 / 2ρV1²+ρgh1=P2+1 / 2ρV2²+ρgh2; Among them, P1 and P2 are the static pressures at two different positions, V1 and V2 are the flow velocities at the corresponding positions, ρ is the fluid density, g is the gravitational acceleration, h1 and h2 are the heights at two different positions. This formula describes that during the flow of the fluid, the sum of its pressure energy, kinetic energy and gravitational potential energy remains unchanged. When the flow rate increases, the static pressure will decrease; conversely, when the flow rate decreases, the static pressure will increase. Therefore, under the same flow rate and pipeline (cross-section) conditions, the fluid flow rate inside the valve will be slower than the fluid flow rate in the pipeline, so that the fluid flow rate inside the valve can be adjusted to reduce the possibility of vortex and turbulence.

[0020] The rubber sleeve 112 is sleeved on the connecting cylinder 110 , and a plurality of adjustment blocks 111 and a plurality of rubber blocks 108 are alternately stacked on the gear plate 106 .

[0021] It should be noted that when the internal aperture becomes smaller, the fluid in the pipeline enters the internal aperture, the flow rate increases, and the pressure on the regulating block 111 and the rubber block 108 is increased. The pressure is borne by the plurality of regulating blocks 111 and the plurality of rubber blocks 108 respectively. At the same time, the pressure causes the rubber block 108 to deform, and the plurality of rubber blocks 108 are connected to each other to form a seal, thereby preventing the fluid from entering the regulating block 111 and the rubber block 108. The plurality of rubber blocks 108 can deform to buffer the pressure, thereby reducing the probability of damage to the regulating block 111. The valve assembly 2 includes a hand wheel 201 , a rotating rod 204 is fixed below the hand wheel 201 , a ball 203 is connected below the rotating rod 204 , a plurality of mounting holes 205 are formed inside the ball 203 , and the ball 203 is arranged inside the valve body 202 .

[0022] It should be noted that by rotating the hand wheel 201 , the hand wheel 201 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the ball 203 to rotate, thereby opening the channel inside the valve body 202 and adjusting the flow of the fluid inside the valve body 202 .

[0023] The power assembly 3 includes a driven gear 304 and a mounting box 305. The mounting box 305 is fixed on the valve body 202. A gear motor 301 is fixed above the mounting box 305. A driving gear 2 303 is fixed on the output shaft of the gear motor 301. The driven gear 304 is fixed on the rotating rod 204. The driven gear 304 and the driving gear 2 303 are meshed. A wireless transceiver 302 is arranged inside the mounting box 305. It should be noted that the gear motor 301 is a stepper motor. When the stepper motor is not in use, the rotating rod 204 can be driven to rotate manually through the hand wheel 201. The wireless transceiver 302 is electrically connected to the gear motor 301 and the rotating motor 101. In the intelligent valve system based on the Internet of Things, the wireless transceiver 302 can communicate with the intelligent gateway or the central control system, receive control instructions from the system, and transmit these instructions to the gear motor 301. After receiving the control instruction, the gear motor 301 will adjust the rotation state of the driving gear 2 303 on its output shaft according to the requirements of the instruction. Since the driving gear 2 303 is meshed with the driven gear 304, when the driving gear 2 303 rotates, the driven gear 304 will also rotate accordingly. The rotational movement of the driven gear 304 will eventually drive the rotating rod 204 to rotate, thereby driving the valve to open or close; The wireless transceiver 302 includes a wireless communication module, a microcontroller, a power management module, a plurality of drive modules and a plurality of feedback sensors, wherein the plurality of drive modules are respectively arranged on the rotating motor 101 and the gear motor 301, and the plurality of feedback sensors are respectively arranged on the rotating motor 101 and the gear motor 301; It should be noted that the wireless transceiver 302 can send and receive wireless control signals through the wireless communication module, including encoding the instructions for controlling the motor into wireless signals, and decoding the received wireless signals to obtain control instructions. The microcontroller can process the received wireless signals and convert them into control instructions that can be recognized by the motor. The drive module can start, stop and adjust the speed of the drive motor according to the control instructions sent by the wireless transceiver. The feedback sensor can monitor the operating status of the motor, such as speed, position, etc., and can also be transmitted to the remote control system in real time through wireless to achieve remote monitoring and fault warning, so that the gear motor 301 can be controlled remotely, which greatly improves the flexibility and convenience of the system, and users can The valve can be operated anywhere through mobile phones, computers and other terminal devices. Through the Internet of Things technology, the wireless transceiver 302 can also feed back the real-time status of the valve (such as opening degree, pressure, etc.) to the central control system, thereby realizing real-time monitoring and fault warning of the valve. It can be controlled remotely, so the safety risks caused by direct contact with the valve can be avoided. At the same time, the real-time monitoring function can also timely discover and solve potential safety hazards. The combination of wireless transceiver 302 and Internet of Things technology can reduce the wiring cost and maintenance cost of the system, avoiding the traditional valve control system that may require a large amount of cables and wiring work, while the smart valve based on the Internet of Things can communicate and control wirelessly; The wireless transceiver 302 can receive and send wireless signals, which facilitates the remote control of the start and stop of the gear motor 301 and the rotating motor 101.

[0024] The gear motor 301 drives the driving gear 2 303 to rotate through the output shaft, the driving gear 2 303 drives the driven gear 304 to rotate, the driven gear 304 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the ball 203 to rotate. The transmission mechanism of the gear motor 301, the driving gear 2 303 and the driven gear 304 can drive the rotating rod to rotate, and cooperate with the power component 3, so that the valve can accurately adjust the fluid flow according to actual needs, and the structure is compact, the footprint is small, and it is easy to adapt to various installation environments. At the same time, it runs smoothly, effectively reduces vibration and noise, and improves the comfort of the working environment.

[0025] The buffer assembly 4 includes a limiting cylinder 404, a connecting column 405 and a limiting block 406. The limiting cylinder 404 is fixed on the rotating rod 204, the connecting column 405 is fixed above the sphere 203, a mounting plate 402 is fixed above the connecting column 405, the mounting plate 402 is slidably arranged inside the limiting cylinder 404, a limiting slot block 401 is fixed above the mounting plate 402, a spring 1 403 is sleeved on the limiting slot block 401, the spring 1 403 is located inside the limiting cylinder 404, the limiting block 406 is fixed below the rotating rod 204, and the limiting block 406 is slidably arranged on the limiting slot block 401; It should be noted that the upper and lower ends of the limiting cylinder 404 are provided with connecting holes, and the spring 1 403 is located between the mounting plate 402 and the limiting cylinder 404; When the ball 203 vibrates, the ball 203 transmits the vibration to the connecting column 405, and the connecting column 405 drives the mounting plate 402 to rise, and the mounting plate 402 drives the limiting groove block 401 to rise, and the limiting groove block 401 rises to squeeze the spring 403, and the spring 403 deforms to absorb the energy generated by the vibration, thereby reducing the energy transmitted to the fasteners and seals of the valve body 202, effectively reducing the vibration, thereby reducing mechanical wear, enhancing the structural strength, ensuring the high sealing performance of the valve, and extending its service life; at the same time, it also greatly reduces the operating noise, avoids the fasteners and seals from loosening or breaking due to vibration, and extends their service life.

[0026] The rectifier assembly 5 includes a plurality of mounting columns 502, wherein a sliding hole is provided inside the mounting column 502, wherein a telescopic column 504 is slidably provided inside the sliding hole, wherein a spring 2 503 is provided between the telescopic column 504 and the sliding hole, wherein a toggle ring block 501 is fixed above the telescopic column 504, wherein a rectifier plate 505 is rotatably provided on the mounting column 502, and the telescopic column 504 is fixed inside the mounting hole 205 at the corresponding position; It should be noted that the cross section of the rectifier plate 505 is teardrop-shaped, and the second spring 503 is made of stainless steel, which has good corrosion resistance, strength and toughness; During installation, the toggle ring blocks 501 at both ends are pressed, and the toggle ring blocks 501 drive the telescopic column 504 to move, and the telescopic column 504 squeezes the second spring 503, and the second spring 503 deforms and contracts, and the telescopic column 504 is inserted into the mounting hole 205 at the corresponding position, and the toggle ring blocks 501 at both ends are loosened, and the second spring 503 drives the telescopic column 504 to rebound, so that the telescopic columns 504 at both ends are inserted into the mounting holes 205 at the corresponding positions, and the installation is completed. At the same time, the telescopic columns 504 at both ends can rotate inside the mounting holes 205 at the corresponding positions; When the sphere 203 rotates open and the fluid enters the interior of the sphere 203 through the hole, the moment the fluid contacts the rectifying plate 505, the flow direction of the fluid will be affected by the shape of the rectifying plate 505. The rectifying plate 505 guides the fluid to flow in a specific direction through its surface shape and angle. Under the action of the rectifying plate 505, the flow of the fluid becomes more stable. The rectifying plate 505 can reduce the generation of eddies and the probability of turbulence in the fluid, thereby improving the stability of the fluid, the uniformity of flow distribution and the accuracy of flow rate control. At the same time, it can also reduce energy loss and protect surrounding equipment or structures, thereby improving the efficiency and reliability of the entire fluid system.

The function of resisting internal pressure is cleverly achieved through the alternating stacking design of a plurality of rubber blocks 108a and a plurality of regulating blocks 111, as well as the mutually staggered layout of the rubber blocks 108a at the same level. The rubber block 108a has good elasticity. When the valve is subjected to pressure, the rubber block 108a can be deformed to absorb and disperse part of the pressure, thereby reducing the impact on the regulating block 111 and increasing its pressure resistance. The regulating blocks 111 play a supporting role in the stacking. They are alternately arranged with the rubber blocks 111 to form a stable supporting structure to maintain the stability and sealing performance of the valve. The staggered arrangement of the rubber blocks 108a at the same level can increase the sealing performance.
