Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic valve devices, in particular to a proportional electromagnetic valve for flow regulation without hysteresis. Background Art

[0002] Solenoid valve is an important device widely used in the field of industrial control and automation. Solenoid valve is an industrial equipment controlled by electromagnetic. It is composed of electromagnetic coil, valve core, valve body and other main components. Its working principle is based on electromagnetic induction phenomenon. When the electromagnetic coil is energized, a magnetic field is generated. The magnetic field enables the valve core to overcome the spring force or other resistance and move, thereby changing the channel state in the valve and realizing the conduction or cutoff of the fluid. In actual applications, there are many types of solenoid valves. According to different working media, such as gas, liquid, steam, etc., there are corresponding special solenoid valves. According to different control methods, they can be divided into direct-acting type, pilot type, etc. Solenoid valves play an important role in many fields such as industrial automation, energy, chemical industry, machinery manufacturing, etc. For example, it is used to control the movement of cylinders in automated production lines, to control the flow of refrigerants in air-conditioning systems, and to control the on and off of liquids or gases in pipelines in the petrochemical industry. In short, as an important control element, the solenoid valve has provided strong support for the development of modern industry and automated control with its high efficiency, precision and reliability. In fluid control systems, proportional solenoid valves, as an important actuator, are widely used in hydraulics, pneumatics, process control and other fields. Proportional solenoid valves are a special type of solenoid valve that can accurately control the flow, direction and pressure of the fluid according to different electrical signals. This valve is widely used in many industrial applications, such as hydraulic systems, automated production lines, etc.

[0003] When the existing proportional solenoid valve is actually used, the interior of the valve port does not have a flow limiting structure. When the flow is transmitted, the flow velocity between the valve port and the pipe body cannot reach the limit. The impact of the flow will cause a gap to appear between the valve core and the valve body. When the valve body stops working, the flow will leak through the gap. Therefore, it is necessary to provide a proportional solenoid valve with hysteresis-free flow regulation to reduce the impact of the flow and achieve the effect of flow limiting.

[0051] The pressure plate 28 is clamped on one side of the outer surface of the mounting ring 4, and one end of the outer surface of the support rod 26 is fixedly connected to the limit block 11, which can play a limiting role to prevent the pressure plate 28 from sliding out during stretching.

The fixing rod 23 is inserted into the inside of the fixing hole 24 to facilitate the installation and disassembly of the anti-wear ring 21.

[0058] Working principle: First, when the pipe body 5 needs to be connected with the first valve port 2 and the second valve port 3, the operator can use the handle 15 to pull out the support plate 31. As the support plate 31 is pulled out, the multiple limit plates 9 originally hidden inside are clearly exposed. At this time, the slider 17 can slide smoothly inside the slide groove 16. According to the specific needs of the actual flow rate and flow velocity, the distance between the multiple limit plates 9 can be flexibly and accurately adjusted. In this process, the screw rod 19 will move synchronously inside the groove body 30 to provide strong support and guarantee for the position adjustment of the limit plate 9. Then, the nut 18 is turned to be tightly fixed on the outer surface of the screw rod 19. In this way, the screw rod 19 can be firmly locked in the position it moves to, thereby effectively fixing the adjusted position of the limit plate 9. Then, the support plate 31 is carefully pushed into the first valve port 2 or the second valve port 3. In this way, during the process of flow transmission, it can be achieved through the hole body 20 opened inside the limit plate 9;

[0059] Then, when the tube body 5 is docked and installed with the first valve port 2 and the second valve port 3 respectively, the pressure plate 28 is strongly stretched by the elastic force generated by the spring 27 itself. This stretching effect enables the pressure plate 28 to be tightly clamped on the outside of the mounting ring 4. The strong elastic force generated by the spring 27 can significantly improve the strength and stability of the pressure plate 28 after being pressed. In this way, when the first valve port 2, the second valve port 3 and the tube body 5 jointly transmit the flow, even if the flow generates a large impact force during the flow, it will not cause slight movement between the first valve port 2, the second valve port 3 and the tube body 5. This greatly improves the stability of the tube body 5 after installation, and effectively avoids leakage or other faults that may be caused by loose connections. At the same time, using multiple limit plates 9 with carefully adjusted positions can effectively reduce the strong impact caused by the flow. These limit plates 9 Like a solid line of defense, it can effectively buffer and limit the flow, thereby achieving the ideal flow limiting effect and ensuring the smoothness, precision and reliability of the entire flow regulation process. Through the close cooperation and collaborative work between various components, this proportional solenoid valve with zero hysteresis flow regulation can perform well in complex industrial environments and provide strong guarantees for the efficient operation of fluid control systems.

All the components are general standard parts or components known to those skilled in the art, and their structures and principles can be understood by those skilled in the art. It is known from technical manuals or through conventional experimental methods that the problem to be solved by the present invention is that when the existing proportional solenoid valve is actually used, the interior of the valve port does not have a flow limiting structure, and when the flow is transmitted, the flow velocity between the valve port and the pipe body cannot reach the limit, and the impact generated by the flow causes a gap to be generated between the valve core and the valve body. When the valve body stops operating, the flow will leak through the gap. Therefore, it is necessary to provide a proportional solenoid valve with hysteresis-free flow regulation to reduce the impact caused by the flow and achieve the effect of flow limiting. The present invention combines the above-mentioned components with each other, provides a support plate inside the first valve port and the second valve port, and provides a plurality of limit plates between the two support plates. When the pipe body needs to be aligned with the first valve port and the second valve port When connecting, use the handle to pull out the support plate so that multiple limit disk lines leak out, and then the slider slides inside the slide groove. According to the flow rate and velocity requirements, the distance between the multiple limit disks is adjusted, and the screw moves inside the groove at the same time. Then, turn the nut so that the nut is fixed on the outer surface of the screw, so that the position moved by the screw can be fixed, and then push the support plate into the first valve port or the second valve port. In this way, the flow is transmitted through the opened hole body during transmission. Using multiple limit disks can reduce the impact caused by the flow, so as to achieve the effect of flow limiting. By providing a fixing block on the outside of the support ring and a pressure plate on the outside of the fixing block, when the pipe body is respectively docked and installed with the first valve port and the second valve port, through The elastic force generated by the spring stretches the pressure plate so that the pressure plate is clamped on the outside of the mounting ring. The elastic force generated by the spring can improve the strength of the pressure plate after being pressed, so that the first valve port, the second valve port and the pipe body will not generate slight movement due to the impact force when transmitting the flow, thereby improving the stability of the pipe body after installation. By providing an anti-wear ring, the plug rods are respectively inserted into the inside of the plug hole, so that the anti-wear ring is fixedly installed on one side of the mounting ring. After the pressure plate presses the mounting ring, it will directly contact the outside of the anti-wear ring, avoiding direct contact with the outside of the mounting ring. The anti-wear ring can be used to improve the anti-wear effect, avoid wear on the outside of the mounting ring, and improve protection.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
