Description

Technical Field

[0001] The utility model relates to the field of fluid control, in particular to a multi-functional regulating valve. Background Art

[0002] In a fluid control system, a multi-functional regulating valve is an indispensable component, which undertakes the important tasks of regulating and controlling fluid flow, including but not limited to key parameters such as fluid flow rate, pressure, and temperature. The control of these parameters is crucial for ensuring the stable operation of the fluid system, optimizing energy utilization, and ensuring production safety.

[0003] However, with the rapid development of industrial technology, especially the continuous progress in automation, intelligence, and high efficiency, the requirements for fluid control have become increasingly complex and diverse. Although traditional regulating valves have met the basic fluid control requirements for a period of time, they gradually expose some design and functional deficiencies when facing these new and higher challenges.

[0004] First of all, when the regulating valve is in the closed state, especially in occasions where rapid closing is required, the water flow (or other fluids) will generate a strong impact force. This impact force directly acts on the valve core of the regulating valve, which may not only cause physical damage to the valve core, such as cracks and deformations, but also affect the regulating accuracy of the regulating valve due to the vibration caused by the impact. The decrease in regulating accuracy will directly affect the stability and operation efficiency of the fluid system, and may even lead to safety accidents.

[0005] Therefore, it is necessary to provide a new multi-functional regulating valve to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides a multi-functional regulating valve.

[0007] The multi-functional regulating valve provided by the utility model includes: a regulating valve body, a sloping groove, and a transmission mechanism. The regulating valve body is composed of an actuating structure and a valve body. A spherical structure is installed at the water inlet of the regulating valve body. A bearing plate is rotatably connected inside the spherical structure. The sloping grooves are symmetrically arranged in the middle of the bearing plate, and the symmetrical sloping grooves are designed in an eight-character shape for flushing the flowing water to reduce the impact force on the valve core of the regulating valve body when the water flow is suddenly blocked. The transmission mechanism is installed on the bearing plate and the actuating structure of the regulating valve body. When the valve body is driven to close by the actuating structure of the regulating valve body, the bearing plate rotates 90 degrees.

[0008] Preferably, the transmission mechanism includes: a guide rod, an extension rod is fixedly connected to the actuating structure of the regulating valve body, one end of the extension rod is fixedly connected to the guide rod, a spiral groove is formed on the outer wall of the guide rod, a driving gear is rotatably connected to the outer wall of the regulating valve body, the center of the driving gear is fitted with the spiral groove on the guide rod, a driven gear is rotatably connected to the outer wall of the spherical structure, and the center of the driven gear is fixedly connected to the middle of the bearing plate.

[0009] Preferably, the axial cross-sectional angle of the spiral groove is 90 degrees.

[0010] Preferably, a flow monitoring device is provided on the valve body part of the regulating valve body for real-time monitoring of the flow rate passing through the regulating valve.

[0011] Preferably, the materials of the spherical structure and the bearing plate are wear-resistant and corrosion-resistant high-strength alloy materials to improve the service life and reliability of the regulating valve.

[0012] Preferably, a lubrication system is provided between the spherical structure and the bearing plate. The lubrication system includes a lubricating oil injection cylinder and a piston. The lubricating oil injection cylinder is installed between the spherical structure and the bearing plate. A piston is slidably connected to the inner wall of the lubricating oil injection cylinder. The piston is fixedly connected to one end of the extension rod. The opening and closing orientation of the actuating structure of the regulating valve body provides lubricating oil between the bearing plate and the spherical structure, further reducing the friction between the two.

[0013] Preferably, an anti-corrosion coating is provided on the inner wall of the inclined groove. The coating can resist the corrosion of water flow and extend the service life of the inclined groove.

[0014] Compared with the related art, the multi-functional regulating valve provided by the present invention has the following beneficial effects:

[0015] By installing a spherical structure with an inclined groove and a bearing plate at the water inlet of the regulating valve, when the regulating valve is closed, the design of the inclined groove can effectively disperse and reduce the impact force generated on the valve core when the water flow is suddenly blocked. This not only protects the valve core from physical damage such as cracks and deformation, but also reduces the vibration caused by the impact, thereby improving the regulation accuracy and stability of the regulating valve.

[0043] The working principle of the multifunctional regulating valve provided by the present utility model is as follows:

[0044] I. Basic working principle

[0045] The multi-functional regulating valve controls the fluid through the valve regulating mechanism. Under normal circumstances, the fluid enters from the valve body and is guided by the valve flap into the downstream pipeline. When it is necessary to adjust the flow rate and pressure of the fluid, the regulating mechanism will adjust the opening degree of the valve flap to achieve precise control of the fluid.

[0046] II. Function of the chute 4

[0047] Reducing the fluid impact force:

[0048] The eight-shaped design of the chute 4 allows the fluid to enter the chute 4. Due to the inclination angle of the chute 4, the fluid is guided and dispersed into two directions;

[0049] This dispersion effectively reduces the direct impact force of the fluid on the valve core, thereby reducing the risk of damage to the valve core;

[0050] The dispersed fluid is guided by the chute 4 and flows to both sides of the chute 4, and meets at the end of the chute 4;

[0051] Since the fluid flows in opposite directions on both sides of the chute 4, when they meet, a counterflush effect will occur;

[0052] This counterflush effect makes the impact forces of the fluid in two directions cancel each other out, further reducing the impact force on the valve core;

[0053] The transmission mechanism 5 includes components such as a guide rod 52, a spiral groove 53, a driving gear 54, and a driven gear 55.

[0054] When the actuator structure of the regulating valve drives the valve body to close, the extension rod 51 will drive the guide rod 52 to rotate. The spiral groove 53 on the outer wall of the guide rod 52 cooperates with the driving gear 54 to convert the rotational motion into a linear motion.

[0055] The rotation of the driving gear 54 will drive the driven gear 55 to rotate, and then drive the carrier plate 3 to rotate 90 degrees. During this process, the angle change of the chute 4 realizes the convection and dispersion effects of the fluid.

[0056] IV. Other features

[0057] Flow monitoring device: The regulating valve body 1 is equipped with a flow monitoring device, which can monitor the flow rate of the fluid passing through the regulating valve in real time, providing data support for the operation of the fluid system.

[0058] Material and Lubrication System 6: The spherical structure 2 and the bearing plate 3 are made of wear-resistant and corrosion-resistant high-strength alloy materials, which improves the service life and reliability of the regulating valve. At the same time, the lubrication system 6 provides lubricating oil between the spherical structure 2 and the bearing plate 3, further reducing friction.
