Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a regulating valve with an energy-saving function. Background Art

[0002] A regulating valve is a valve used to control the flow rate, pressure and temperature of a fluid, and is usually used in a fluid control system during industrial production. The regulating valve adjusts the flow rate and pressure of the fluid by changing the opening degree of the valve, so as to achieve the control of the fluid system.

[0003] The regulating valve is usually installed on a pipeline for adjustment. In the existing connection and use of the regulating valve and the pipeline, since the caliber of the pipeline is relatively fixed, and the flow rate and velocity of the fluid passing through the pipeline are inconsistent. When the flow rate is large, it is necessary to expand the inlet caliber, and when the flow rate is small, it is necessary to reduce the inlet caliber. Therefore, it is necessary to frequently change the caliber of the pipeline to adapt to the fluid flow rate. Frequent replacement will cause wear of the regulating valve, and when the fluid flow rate passes through an inappropriate pipeline, the flow velocity of the fluid in the pipeline will be uneven. The place with too fast flow velocity will increase the resistance, resulting in the generation of eddy currents and flow losses, thereby increasing the overall pressure loss of the system. The regulating valve requires a larger pressure difference to achieve the same flow rate adjustment, resulting in too large an opening degree, and thus increasing the energy consumption. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a regulating valve with an energy-saving function.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A regulating valve with an energy-saving function includes a valve body. A medium pipeline is arranged inside the valve body, and the medium pipeline is communicated with the inside of the valve body. Support seats are fixedly connected to both sides of the valve body. The support seats are fixedly connected with a support ring through support rods. A chute is opened on the inner wall of the support ring. A gear ring is slidably connected in the chute. A connecting shaft is fixedly connected to the inner bottom of the support ring. The end of the connecting shaft is connected with a baffle page. Tooth edges are opened on the outer wall of the baffle page, and the tooth edges are meshed with the gear ring.

[0007] Preferably, a support column is fixedly connected to the support seat on the right side of the valve body. A driving motor is arranged at the end of the support column. The output end of the driving motor is connected with a driving gear. A rack edge is opened on the outer wall of the gear ring, and the rack edge is meshed with the driving gear.

[0008] Preferably, an electric cylinder is arranged on the side wall of the valve body through a connecting frame. The output end of the electric cylinder is connected with a driving rod, and the end of the driving rod is connected with a connecting handle.

[0009] Preferably, a circular hole is formed on the side of the connecting handle away from the driving rod. A connecting rod is arranged in the circular hole. One end of the connecting rod penetrates through the support seat and extends into the interior of the valve body and is fixedly connected with a support clamping plate. A valve flap is arranged in the support clamping plate.

[0010] The beneficial effects of the present utility model are as follows:

[0011] The driving motor drives the driving gear to rotate. The rotation of the driving gear drives the rack edge to engage and rotate. When the rack edge rotates, it drives the gear ring to rotate. When the gear ring rotates, it drives the baffle flap to rotate successively with the connecting shaft as the fulcrum. When the baffle flap rotates, its end gradually closes or extends towards the medium pipeline, which can change the flow rate or flow velocity of the fluid passing through the medium pipeline, is beneficial for making adaptive adjustments according to needs in the face of different flow rate changes, avoids the cumbersome process of frequently replacing medium pipelines with different calibers, reduces the resistance loss and energy consumption in the medium pipeline, and improves the flexibility and response ability of the entire regulating valve.

[0020] Embodiment:

[0021] Refer to Figures 1-3 , a control valve with energy-saving function, which includes a valve body 1. A medium pipeline 2 is arranged inside the valve body 1, and the medium pipeline 2 is communicated with the inside of the valve body 1. Support seats 3 are fixedly connected to both sides of the valve body 1. The support seats 3 are fixedly connected with a support ring 5 through a support rod 4. A chute is opened on the inner wall of the support ring 5, and a gear ring 6 is slidably connected in the chute. A connecting shaft 7 is fixedly connected to the inner bottom of the support ring 5, and the end of the connecting shaft 7 is connected with a baffle page 8. Tooth edges are opened on the outer wall of the baffle page 8, and the tooth edges are meshed with the gear ring 6.

[0022] A support column 9 is fixedly connected to the support seat 3 on the right side of the valve body 1. A driving motor 10 is arranged at the end of the support column 9. The output end of the driving motor 10 is connected with a driving gear 11. A rack edge 12 is opened on the outer wall of the gear ring 6, and the rack edge 12 is meshed with the driving gear 11.

[0023] An electric cylinder 14 is arranged on the side wall of the valve body 1 through a connecting frame 13. The output end of the electric cylinder 14 is connected with a driving rod 15, and the end of the driving rod 15 is connected with a connecting handle 16.

[0024] A circular hole is opened on one side of the connecting handle 16 away from the driving rod 15. A connecting rod 17 is arranged in the circular hole. One end of the connecting rod 17 penetrates through the support seat 3 and extends into the inside of the valve body 1 and is fixedly connected with a support clamping plate 18. A valve page 19 is arranged in the support clamping plate 18.

[0025] In this embodiment, when it is necessary to adjust the size of the fluid flow rate, when the required adjusted fluid flow rate is smaller than the volume of the medium pipeline 2, first start the driving motor 10 to drive the driving gear 11 to rotate. When the driving gear 11 rotates, it drives the rack edge 12 to engage and rotate. When the rack edge 12 rotates, it drives the gear ring 6 to rotate clockwise. When the gear ring 6 rotates, it drives the baffle page 8 to rotate successively with the connecting shaft 7 as the fulcrum. While the baffle page 8 rotates, its end gradually shrinks and closes towards the center of the medium pipeline 2, thereby blocking the caliber of the medium pipeline 2 and changing the caliber of the fluid flow passing through the medium pipeline 2. When the flow rate is too large, reverse start the driving motor 10 to drive the driving gear 11 to rotate, and repeat the above operations in reverse, so that the baffle page 8 moves outward with the connecting shaft 7 as the fulcrum. At this time, the caliber of the fluid flow passing through the medium pipeline 2 increases, so as to effectively control the fluid flow rate, and can make adaptive adjustments according to different flow rate changes as needed, improving the flexibility and response ability of the entire system. At the same time, it avoids the cumbersome process of frequently replacing medium pipelines 2 with different calibers, reduces the resistance loss in the medium pipeline 2, reduces the system pressure, and reduces the energy consumption in the system.

[0026] Furthermore, when the fluid enters the valve body 1 through the medium pipeline 2, start the electric cylinder 14 at this time. When the electric cylinder 14 operates, it pushes the driving rod 15 upward. While the driving rod 15 moves upward, it drives one end of the connecting handle 16 to rotate counterclockwise with the support seat 3 as the fulcrum. Thus, when the connecting handle 16 rotates, it drives the connecting rod 17 to rotate. When the connecting rod 17 rotates, it can make the support clamp 18 drive the valve page 19 to flip, so as to further adjust the fluid flow rate passing through the valve body 1.
