Description

Technical Field

[0001] This utility model relates to the field of valves, and more specifically, to a balancing valve for precision flow control. Background Technology

[0002] In hydraulic, HVAC, and industrial fluid control systems, the balancing valve is a core component for regulating fluid flow and pressure, and its control accuracy directly determines the system's operating efficiency and energy consumption level.

[0003] A search revealed that Chinese patent CN221824617U, disclosed in the prior art, discloses a "High-Precision Flow Control Temperature Sensing Dynamic Balancing Valve," which includes a valve body with a valve cavity. The valve body has an inlet and an outlet at both ends, and a valve ball assembly for controlling the valve orifice size is located between the inlet and outlet. The valve also includes an actuator and a flow monitoring component. The actuator is fixedly mounted on the valve body and connected to the valve ball assembly. The flow monitoring component is located inside the valve cavity and monitors the flow rate inside the valve body in real time. The flow monitoring component is electrically connected to the actuator and controls the valve ball assembly to change the flow rate inside the valve body. When the flow velocity inside the valve cavity is high, the flow monitoring component sends an electrical signal to the actuator, causing the actuator to control the valve ball assembly to rotate and increase the valve orifice area. When the flow velocity inside the valve cavity is low, the valve orifice area is reduced, thereby achieving precise and real-time flow control. However, it still has the following drawbacks: (1) Once the valve is damaged, the fluid will not be effectively shut off and will continue to flow out. This will not only waste resources, but may also cause a series of safety hazards and secondary problems.

[0004] (2) Various impurities contained in the liquid are very likely to accumulate in key parts such as pipes and valves, which can lead to serious blockage, accelerate component wear, shorten equipment service life, and increase maintenance costs and downtime risks.

[0005] To address this, a balancing valve with precise flow control is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that, in the current technology, once a valve is damaged, the fluid cannot be effectively shut off, resulting in continuous outflow. This not only wastes resources but may also cause a series of safety hazards and secondary problems. The invention provides a precision flow control balancing valve to solve the problems mentioned in the background.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a balance valve for precision flow control, comprising a valve body, wherein a regulating component for adjusting flow is provided through the valve body, and a filter component for filtering fluid is fixedly installed inside the regulating component; The adjusting assembly includes an upper connector that penetrates through the valve body. A base is fixedly installed on the top of the upper connector, and a telescopic cylinder is fixedly installed on the top of the base. A telescopic rod is fitted to one end of the telescopic cylinder. The telescopic rod is located inside the upper connector, and a baffle is fixedly installed at the other end of the telescopic rod. A circular hole is provided on the baffle, and a compression spring is fixedly installed at the bottom of the baffle.

[0008] As a preferred technical solution of this utility model, the filter assembly includes a fluid cavity fixedly installed inside the valve body, sealing gaskets fixedly installed on both sides of the fluid cavity, a groove is opened on the inner side of the valve body, the sealing gasket is located in the groove and the outer side of the sealing gasket is tightly fitted with the inner side wall of the groove, a gasket is fixedly installed on the inner side of the fluid cavity, and a filter screen is fixedly installed on the inner side of the gasket, with one side of the filter screen tightly fitted with one side of the baffle.

[0009] As a preferred technical solution of this utility model, a lower connector is provided through the valve body, a sealing cap is provided at the bottom of the lower connector, and a drain pipe is provided through the sealing cap.

[0010] As a preferred technical solution of this utility model, the other end of the compression spring is fixedly connected to the top of the sealing cover, and the compression spring is evenly distributed in three groups.

[0011] As a preferred technical solution of this utility model, a first flange and a second flange are respectively connected to both sides of the valve body. The first flange and the second flange correspond to the liquid inlet and the liquid outlet, respectively. A protective shell is fixedly installed on the top of the base, and the protective shell is located on the outside of the telescopic cylinder.

[0012] As a preferred technical solution of this utility model, a positioning pin is provided through the valve body, the fluid cavity, and the gasket, and there are two sets of positioning pins arranged symmetrically.

[0013] As a preferred technical solution of this utility model, a limiting hole is provided on the fluid cavity, the baffle slides inside the limiting hole, and the circular hole corresponds to the fluid cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the telescopic cylinder starts operating, it drives the telescopic rod that it works with to extend and retract. During the extension and retraction of the telescopic rod, it drives the baffle installed at its end to move accordingly inside the upper connector. When the baffle moves, the position of the circular hole inside the valve also changes accordingly. By precisely adjusting the position of the circular hole, the amount of fluid passing through the valve can be accurately controlled. When the telescopic cylinder stops operating, the compression spring, with its good elasticity, helps the baffle to quickly and smoothly return to a stable position. At this time, the baffle rises and effectively blocks the fluid from passing through. Even if the telescopic cylinder malfunctions, it can prevent continuous fluid leakage, thereby ensuring that the entire flow regulation process can be carried out reliably and stably. 2. When fluid passes through the valve body, it first enters the fluid chamber. The sealing gaskets on both sides of the fluid chamber fit tightly against the grooves on the inside of the valve body, effectively preventing fluid leakage and ensuring precise flow control. At the same time, the gaskets on the inside of the fluid chamber further enhance the sealing effect and provide stable support for the filter screen. When the fluid passes through, the filter screen can intercept impurities and particles in the fluid, preventing them from entering the subsequent pipeline system, thereby ensuring the purity of the fluid and the normal operation of the system. This not only improves the filtration performance of the balancing valve but also extends the service life of the valve and pipeline system. Attached Figure Description

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] like Figure 1 and Figure 2 As shown, this embodiment proposes a precision flow control balancing valve, including a valve body 1, an adjustment component 2 for adjusting the flow rate is provided through the valve body 1, and a filter component 3 for filtering the fluid is fixedly installed inside the adjustment component 2. like Figures 1-4 As shown, the adjusting assembly 2 includes an upper connector 201 that passes through the valve body 1. A base 202 is fixedly installed on the top of the upper connector 201. A telescopic cylinder 203 is fixedly installed on the top of the base 202. A telescopic rod 204 is installed at one end of the telescopic cylinder 203. The telescopic rod 204 is located inside the upper connector 201. A baffle 205 is fixedly installed at the other end of the telescopic rod 204. A circular hole 206 is opened on the baffle 205. A compression spring 207 is fixedly installed at the bottom of the baffle 205. When the telescopic cylinder 203 starts operating, it drives the telescopic rod 204 to extend and retract. During the extension and retraction of the telescopic rod 204, it causes the baffle 205 installed at its end to move accordingly inside the upper connector 201. When the baffle 205 moves, the position of the circular hole 206 inside the valve also changes accordingly. By precisely adjusting the position of the circular hole 206, the amount of fluid passing through the valve can be accurately controlled. When the telescopic cylinder 203 stops operating, the compression spring 207, with its good elasticity, helps the baffle 205 to quickly and smoothly return to a stable position. At this time, the baffle 205 rises and effectively blocks the flow of fluid. Even if the telescopic cylinder 203 malfunctions, it can prevent continuous leakage of fluid, thereby ensuring that the entire flow regulation process can be carried out reliably and stably.

[0022] like Figures 1-3 and Figure 5 As shown, the filter assembly 3 includes a fluid chamber 301 fixedly installed inside the valve body 1. Sealing gaskets 302 are fixedly installed on both sides of the fluid chamber 301. A groove 303 is opened on the inner side of the valve body 1. The sealing gasket 302 is located in the groove 303 and the outer side of the sealing gasket 302 is tightly fitted with the inner sidewall of the groove 303. A gasket 304 is fixedly installed on the inner side of the fluid chamber 301. A filter screen 305 is fixedly installed on the inner side of the gasket 304. One side of the filter screen 305 is tightly fitted with one side of the baffle 205. When fluid passes through valve body 1, it first enters fluid chamber 301. The sealing gaskets 302 on both sides of fluid chamber 301 fit tightly with the grooves 303 on the inner side of valve body 1, effectively preventing fluid leakage and ensuring precise flow control. At the same time, the gaskets 304 on the inner side of fluid chamber 301 further enhance the sealing effect and provide stable support for filter screen 305. When fluid passes through, filter screen 305 can intercept impurities and particles in the fluid, preventing them from entering the subsequent pipeline system, thereby ensuring the purity of the fluid and the normal operation of the system. This not only improves the filtration performance of the balancing valve but also extends the service life of the valve and pipeline system.

[0023] like Figures 1-4 As shown, a lower connector 208 is provided through the valve body 1, and a sealing cover 209 is provided at the bottom of the lower connector 208. A drain pipe 210 is provided through the sealing cover 209. The sealing cover 209 prevents fluid leakage, and the drain pipe 210 can discharge the liquid in the valve body 1 or clean and filter impurities, so as to avoid impurities clogging the valve body 1 and ensure the normal operation of the valve body 1.

[0024] like Figure 3 and Figure 4 As shown, the other end of the compression spring 207 is fixedly connected to the top of the sealing cover 209, and there are three sets of compression springs 207 evenly distributed. When the baffle 205 moves, the compression spring 207 generates elastic force, providing a restoring force for the baffle 205, so that the baffle 205 can accurately return to the initial position, ensuring the stability of flow regulation.

[0025] like Figures 1-4 As shown, a first flange 211 and a second flange 212 are connected to both sides of the valve body 1, respectively. The first flange 211 and the second flange 212 correspond to the liquid inlet and the liquid outlet, respectively. A protective shell 213 is fixedly installed on the top of the base 202, and the protective shell 213 is located on the outside of the telescopic cylinder 203. The first flange 211 and the second flange 212 connect the valve body 1 to the pipeline, and the protective shell 213 protects the telescopic cylinder 203 from the influence of the external environment, extending the service life of the telescopic cylinder 203.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a positioning pin 214 is provided through the valve body 1, the fluid chamber 301, and the gasket 304. There are two sets of positioning pins 214, which are symmetrically arranged. This ensures that the fluid chamber 301 and the gasket 304 are accurately positioned within the valve body 1, preventing their movement from affecting flow control and filtration effect.

[0027] like Figures 3-5 As shown, a limiting hole 306 is provided on the fluid cavity 301, and a baffle 205 slides inside the limiting hole 306. The circular hole 206 corresponds to the fluid cavity 301. The limiting hole 306 ensures that the movement direction of the baffle 205 is accurate. By adjusting the movement of the baffle 205, the overlapping area of ​​the circular hole 206 and the fluid cavity 301 is adjusted, thereby adjusting the flow rate.

[0028] Specifically, when using this precision flow control balancing valve: The telescopic cylinder 203 is activated, driving the corresponding telescopic rod 204 to extend and retract. During this process, the telescopic rod 204 moves the baffle 205 at its end within the upper connector 201. As the baffle 205 moves, the position of the circular orifice 206 within the valve changes accordingly. By precisely adjusting the position of the circular orifice 206, accurate control of the fluid flow through the valve can be achieved. When the telescopic cylinder 203 stops operating, the compression spring 207, with its excellent elasticity, assists the baffle 205 to quickly and smoothly return to its stable position. At this point, the baffle 205 rises and effectively blocks the fluid flow. Even if the telescopic cylinder 203 malfunctions, continuous fluid leakage can be avoided, thus ensuring that the entire flow regulation process can be carried out reliably and stably. When the fluid passes through the valve body 1, it first enters the fluid chamber 301. The sealing gaskets 302 on both sides of the fluid chamber 301 fit tightly with the grooves 303 on the inner side of the valve body 1, effectively preventing fluid leakage and ensuring accurate flow control. At the same time, the gaskets 304 on the inner side of the fluid chamber 301 further enhance the sealing effect and provide stable support for the filter screen 305. When the fluid passes through, the filter screen 305 can intercept impurities and particles in the fluid, preventing them from entering the subsequent pipeline system, thereby ensuring the purity of the fluid and the normal operation of the system.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
