Description

Technical Field

[0001] This utility model relates to the field of HVAC valves, and in particular to a split-type adjustable flow dynamic balancing valve. Background Technology

[0002] Dynamic balancing valves are used in pipeline systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning. They can automatically keep the system flow constant at the required set value, thereby automatically eliminating hydraulic imbalance caused by various factors in the system.

[0003] Chinese patent CN204025809U discloses an adjustable flow dynamic balancing valve. This utility model uses an indicator panel and an electric actuator to drive the valve stem to rotate and move up and down, thereby controlling the outlet area of ​​the valve and effectively realizing the real-time flow regulation of the valve. The improved dynamic balancing valve achieves the balance and real-time regulation of dynamic flow in the pipeline system.

[0004] Taking the above-mentioned utility model as an example, when the existing dynamic balancing valve adjusts the pressure difference, the flow rate of the liquid substance inside changes, causing a large amount of liquid substance to accelerate the frequency of rubbing against the inner wall of the valve body in a short period of time, thereby causing noise. When used in residential areas, a sealing shell is usually installed for sealing and noise reduction. This method has considerations of large footprint and installation and fixation. Therefore, this utility model proposes: a split-type adjustable flow dynamic balancing valve. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a split-type adjustable flow dynamic balancing valve.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a split-type adjustable flow dynamic balance valve, comprising a valve body, a mounting cover, an output end, an input end, an electrically controlled push cylinder, a mounting sleeve, a valve stem spring, a pressure reducing device, a valve stem, a valve core, a flow guide hole, a diaphragm, a flow sensor, a display screen, and a closing block. The valve body has an output end at its left end, and the mounting cover is fitted to the top of the valve body by studs. The electrically controlled push cylinder is installed inside the mounting cover.

[0007] The electrically controlled push cylinder is connected to the top of the valve stem via a transmission connection. The input end is located at the right end of the valve body. The mounting sleeve is located at the top of the valve body, and a valve stem spring is fitted at the bottom of the mounting sleeve. The valve stem is slidably connected to the axis of the mounting sleeve via the valve stem spring. A valve core is located at the bottom of the valve stem. The mounting sleeve is located at the top of the valve body, and a valve stem spring is fitted at the bottom of the mounting sleeve. The bottom of the valve stem spring is fixed to the outer side of the valve stem. The valve stem is slidably connected to the axis of the mounting sleeve via the valve stem spring. A valve core is located at the bottom of the valve stem. Two sets of pressure-reducing devices are provided, symmetrically arranged on the left and right sides inside the valve body.

[0008] As an improvement to the split-type adjustable flow dynamic balancing valve, the pressure reducing device includes a mounting base, a built-in motor, a lifting rod, a drive main wheel, a driven wheel, a drive belt, a meshing plate, a flow limiting groove, and a limiting cover plate. The mounting base is fixed to the bottom of the valve body. The built-in motor is mounted below the bottom of the mounting base. The built-in motor is connected to the bottom of the drive main wheel via a coupling. The lifting rod is connected to the front end of the limiting cover plate. The limiting cover plate is mounted on the top of the flow limiting groove.

[0009] As an improvement to the split-type adjustable flow dynamic balancing valve, the limiting cover includes a movable cover, a transmission sleeve, a flip joint, a flow-limiting net, a mounting soft layer, and a sound insulation layer. The flip joint is installed inside the movable cover. The transmission sleeve is located on the outside of the movable cover and is fitted and fixed to the top of the lifting rod. The mounting soft layer is assembled at the bottom of the flip joint. A flow-limiting net is laid inside the mounting soft layer. The mounting soft layer is fixed to the inside of the flow-limiting groove. Both the flow-limiting groove and the limiting cover have a sound insulation layer inside.

[0010] As an improvement to the split-type adjustable flow dynamic balance valve, the valve core has a flow guide hole inside, and a diaphragm is laid inside the flow guide hole. The top of the diaphragm is connected to a flow sensor through a built-in wiring harness. The flow sensor is electrically connected to an electronically controlled push cylinder through a network signal. The display screen is connected to the top of the flow sensor through a wire. The closing block is located at the lower end of the valve body and is slidably connected to the right end of the valve core.

[0011] As an improvement to the split-type adjustable flow dynamic balance valve, the transmission main wheel has two transmission grooves inside. The transmission main wheel is connected to the transmission belt through the two sets of transmission grooves. The right end of the transmission belt is connected to the outside of the driven wheel. The driven wheel is mounted on the bottom of the lifting rod. The connection between the lifting rod and the meshing plate is threaded, and the two are threadedly engaged with each other. The meshing plate is located inside the mounting base, and the flow limiting groove is located inside the valve body.

[0012] As an improvement to the split-type adjustable flow dynamic balance valve, the flip joint is a hinge structure that can flip horizontally. The flip joint is arranged parallel to the inside of the movable cover plate, and a flow limiting net is provided at the bottom of the flip joint.

[0013] As an improvement to the split-type adjustable flow dynamic balance valve, when the flow limiting groove and the limiting cover are assembled, the flow limiting net inside the limiting cover will tilt to the same side. The flow limiting net is a mesh fiber layer composed of a large number of square filter holes. When the two sets of flow limiting nets intertwine, they play a preliminary buffering role on the flow inside the valve body, thereby playing a role in buffering and noise reduction.

[0014] As an improvement to the split-type adjustable flow dynamic balancing valve, the mounting soft layer is made of synthetic rubber, which has sufficient toughness and corrosion resistance (similar to rubber tires). The flow sensor is an FD series integrated intelligent water source flow device.

[0015] Compared with the prior art, this utility model provides a split-type adjustable flow dynamic balancing valve, which has the following advantages:

[0016] Advantages: This utility model incorporates a pressure-reducing device. An internal motor drives the transmission main wheel to rotate. The transmission main wheel, through two sets of internal transmission grooves, engages with a corresponding transmission belt for frictional transmission. The transmission belt drives the driven wheel to rotate, which in turn drives the lifting rod to rotate. The lifting rod meshes with the meshing plate, causing it to move downwards and upwards. By adjusting the position of the limiting cover and the flow-limiting groove, the lifting rod can reduce the impact force of the flow according to the flow rate, preventing excessively rapid flow of liquid after the valve core detaches, which could cause noise. Furthermore, by assembling the pressure-reducing device at both the output and input ends, and by adjusting its own guidance to disperse the liquid to the right, the flow rate and impact force of the liquid are weakened, thus reducing the noise generated when the liquid rubs against the valve body. This noise reduction mechanism mitigates the impact of the equipment in residential areas.

[0017] By installing a flow-limiting groove and a limiting cover plate at the upper end of the pressure-reducing device, and by pulling the movable cover plate downward through the transmission sleeve, the movable cover plate covers the top of the transmission sleeve to form a flow-limiting tube. Most of the flow is introduced into the interior of the flow-limiting tube, while a small amount of flow flows through the outside of the flow-limiting tube, thus completing the severe flow diversion and pressure reduction. During the downward movement of the movable cover plate, the two sets of mounting soft layers tilt to the same side with the assistance of correspondingly set flip joints. The flow-limiting mesh set inside the two sets of mounting soft layers intertwines with each other. The filter mesh inside the flow-limiting mesh limits and guides the outward flow, which weakens the impact force of the liquid substance. In this way, the position of the limiting cover plate and the flow-limiting groove can be adjusted by the lifting rod, so that both can weaken the impact force of the flow according to the flow conditions.

Detailed Implementation

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] Please see Figure 1 and Figure 2 This utility model provides a split-type adjustable flow dynamic balance valve through improvement, including valve body 1, mounting cover 2, output end 3, input end 4, electric control push cylinder 5, mounting sleeve 6, valve stem spring 7, pressure reducing device 8, valve stem 9, valve core 10, guide hole 11, diaphragm 12, flow sensor 13, and display screen 14.

[0028] Please see Figure 3 and Figure 4 This utility model provides a split-type adjustable flow dynamic balance valve through improvements. The pressure reducing device 8 includes a mounting base 81, a built-in motor 82, a lifting rod 83, a transmission main wheel 84, a driven wheel 85, a transmission belt 86, a meshing plate 87, a flow limiting groove 88, and a limiting cover plate 89. The mounting base 81 is fixed to the bottom of the valve body 1. The built-in motor 82 is mounted below the bottom of the mounting base 81. The built-in motor 82 is connected to the bottom of the transmission main wheel 84 by a coupling. The lifting rod 83 is connected to the front end of the limiting cover plate 89. The transmission main wheel 84 has two transmission grooves inside. The transmission main wheel 84 is connected to the transmission belt 86 through the two sets of transmission grooves. The right end of the transmission belt 86 is connected to the outside of the driven wheel 85.

[0029] Driven wheel 85 is mounted on the bottom of lifting rod 83. The connection between lifting rod 83 and meshing plate 87 is threaded, and the two are threadedly engaged. Meshing plate 87 is located inside mounting base 81. Flow limiting groove 88 is located inside valve body 1. Limiting cover plate 89 is mounted on top of flow limiting groove 88. The transmission main wheel 84 has two transmission grooves inside. Transmission belts 86 are mounted on the outer sides of both sets of transmission grooves. The right end of transmission belt 86 is connected to the outer side of driven wheel 85. Driven wheel 85 is mounted on the bottom of lifting rod 83. The connection between lifting rod 83 and meshing plate 87 is threaded, and the two are threadedly engaged. Meshing plate 87 is located inside mounting base 81. Flow limiting groove 88 is located inside valve body 1.

[0030] Please see Figure 5This utility model provides a split-type adjustable flow dynamic balance valve through improvements. The limiting cover 89 includes a movable cover 891, a transmission sleeve 892, a flip joint 893, a flow limiting net 894, a mounting soft layer 895, and a sound insulation layer 896. The flip joint 893 is installed inside the movable cover 891. The transmission sleeve 892 is located on the outside of the movable cover 891 and is fitted and fixed to the top of the lifting rod 83. The mounting soft layer 895 is assembled at the bottom of the flip joint 893. The flow limiting net 894 is laid inside the mounting soft layer 895. The mounting soft layer 895 is fixed to the inside of the flow limiting groove 88. The sound insulation layer 896 is provided inside both the flow limiting groove 88 and the limiting cover 89.

[0031] refer to Figures 1-5 When in use, the device is assembled at the connection end between the heating equipment and the gas transmission equipment, so that the gas transmission equipment provides output liquid substance to the heating equipment. The liquid substance flows from the input end 4 into the left end of the valve body 1 for storage.

[0032] By activating the electric control push cylinder 5 to retract upwards, it pushes out the support for the valve stem 9. With the assistance of the valve stem spring 7, the valve stem 9 retracts inwards along the axis of the mounting sleeve 6, causing the valve core 10 to move upwards. When the guide hole 11 pushes out of the height of the closing block 15, the guide hole 11 can normally flow and transmit liquid substances.

[0033] Meanwhile, since the electric control push cylinder 5 and the valve stem 9 are not fixed but are connected separately, when the electric control push cylinder 5 fails, the operator can manually move the protrusion at the front end of the valve stem 9, which can extend and retract along the valve body 1, ensuring that the valve core 10 set below the valve body 1 can adapt to emergencies and ensure the usability of the equipment.

[0034] Simultaneously, the built-in motor 82 drives the transmission main wheel 84 to rotate. The transmission main wheel 84 has two sets of transmission grooves inside it, which interact with the corresponding transmission belt 86 through friction. The transmission belt 86 drives the driven wheel 85 to rotate, and the driven wheel 85 drives the lifting rod 83 to rotate. The lifting rod 83 engages with the meshing plate 87, causing the lifting rod 83 to move downwards. The lifting rod 83 pulls the movable cover plate 891 downwards through the transmission sleeve 892, so that the movable cover plate 891 covers the top of the transmission sleeve 892 and splices to form a flow-limiting tube. Most of the flow is introduced into the interior of the flow-limiting tube, and a small amount of flow flows through the outside of the flow-limiting tube, thus completing the severe flow diversion and pressure reduction.

[0035] During the downward movement of the movable cover plate 891, the two sets of mounting soft layers 895 tilt to the same side with the assistance of the corresponding flip joints 893. The flow-limiting nets 894 set inside the two sets of mounting soft layers 895 intertwine with each other. The filter mesh inside the flow-limiting net 894 restricts and guides the outward flow, which weakens the impact force of the liquid substance. Then, the position of the limiting cover plate 89 and the flow-limiting groove 88 is adjusted by the lifting rod 83, so that the two can weaken the impact force of the flow according to the flow situation. This avoids the liquid substance flowing too quickly after the valve core 10 is separated, which would cause noise. In this way, by assembling the pressure reducing device 8 at the output end 3 and the input end 4, the liquid substance is guided to the right by adjusting itself, and the flow rate and impact force of the liquid substance are weakened. This reduces the noise generated when the liquid substance rubs against the valve body 1, and thus weakens the impact of the equipment in the living area through the noise reduction of the equipment itself.

The wiring diagram of the power element and the supply of power are common knowledge in the field.
