Description

Technical Field

[0001] This utility model relates to the field of flow control device technology, and in particular to a novel flow control device. Background Technology

[0002] A flow control device is a mechanical device or electromechanical system used to regulate, limit, or stabilize the flow rate (i.e., flow rate) of a fluid (liquid, gas, or gas-solid / liquid-solid mixture) in a pipe or other carrier.

[0003] Existing flow control devices are generally installed by directly connecting them to the required pipeline. During subsequent use, when maintenance is required, the terminal valves on the pipeline must be closed to stop the flow of fluid in the pipeline before disassembly and maintenance can be carried out. This is not only cumbersome, but also affects the flow of fluid in the pipeline.

[0004] Therefore, it is necessary to provide a new type of flow control device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a novel flow control device.

[0006] The novel flow control device provided by this utility model includes: a flow control valve, and the flow control valve is provided with a docking assembly;

[0007] The docking assembly includes an adapter pipe, both ends of which are fixedly installed with adapters communicating with it. Each of the two adapters has a gate valve at its opposite end, and the ends of the two gate valves away from the adapters are respectively connected to the ends of the flow control valves.

[0008] Preferably, a transfer frame communicating with the interior is fixedly installed on one side of the transfer tube, a one-way valve is sleeved on the transfer tube, and a sampling tube is projected from the bottom of the transfer frame through a threaded structure.

[0009] Preferably, the top of the adapter frame is provided with a top cover, and a sealing plate is movably installed inside the top cover to seal the connection between the adapter frame and the adapter pipe, and one side wall of the top cover and the adapter frame are both transparent glass.

[0010] Preferably, the top cover is internally provided with a rotating rod that is rotatably connected and a guide rod that is fixedly connected. The outer wall of the rotating rod is threadedly connected to the inside of the sealing plate, and the outer wall of the guide rod abuts against and slides against the inner wall of the sealing plate.

[0011] Preferably, a mounting frame is fixedly connected to one side wall of the top cover, one end of the rotating rod extends into the mounting frame and is rotatably connected to the inner wall of the mounting frame, and a worm gear is fixedly connected to the outer wall of the rotating rod inside the mounting frame.

[0012] Preferably, a rotatably connected drive rod is mounted inside the mounting frame, and a fixedly connected worm gear is sleeved on the outer wall of the drive rod, with the worm gear meshing with a worm wheel.

[0013] Compared with related technologies, the novel flow control device provided by this utility model has the following beneficial effects:

[0014] 1. In subsequent use, when the flow control valve needs to be repaired, the gate valves at both ends of the transfer pipe can be closed, so that the liquid flowing in the pipeline can flow through the transfer pipe. Thus, the pipeline installed with this device can still work normally when the flow control valve is repaired, avoiding the impact on the liquid flow state in the pipeline.

[0015] 2. By setting up a sampling tube, this utility model allows the sealing plate inside the adapter frame to be opened during use, so that the liquid in the pipeline can flow into the adapter frame and its internal sampling tube, thereby enabling the collection and sampling of the liquid flowing in the pipeline. This makes it more convenient for staff to take samples when they need to test the fluid, thus improving the user experience of this device. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 The present invention provides a novel flow control device, which includes a flow control valve 1.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 The flow control valve 1 is provided with a docking assembly 2; the docking assembly 2 includes a transfer pipe 21, both ends of which are fixedly installed with adapters 211 that communicate with it, and the opposite ends of the two adapters 211 are provided with gate valves 212, and the ends of the two gate valves 212 away from the adapters 211 are respectively connected to the corresponding ends of the flow control valve 1.

[0025] It should be noted that, through the setting of the docking component 2, when the flow control valve 1 needs to be repaired during subsequent use, the gate valves 212 at both ends of the transfer pipe 21 can be closed to achieve distribution at both ends of the flow control valve 1, so that the liquid flowing in the pipeline can flow through the transfer pipe 21. This allows the pipeline installed in this device to still work normally when the flow control valve 1 is repaired, avoiding the impact on the liquid flow state in the pipeline.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4 A connecting frame 22 is fixedly installed on one side of the connecting pipe 21 and communicates with its interior. A one-way valve 23 is fitted on the connecting pipe 21, and a sampling tube 221 is projected from the bottom of the connecting frame 22 through a threaded structure. A top cover 3 is provided on the top of the connecting frame 22. A sealing plate 321 is movably installed inside the top cover 3 to seal the connection between the connecting frame 22 and the connecting pipe 21. One side wall of the top cover 3 and the connecting frame 22 are both transparent glass.

[0027] It should be noted that: by setting up the transparent plate, when the staff needs to perform sampling operations, the transparent plate allows the staff to see the state of the liquid inside the transfer frame 22 more clearly, thereby allowing the staff to control the sampled liquid more accurately and reduce the phenomenon of excessive liquid collection, which may lead to overfilling of the sampling tube 221 and leakage.

[0028] By setting up the one-way valve 23, during use, the one-way valve 23 can be placed in the pipeline so that the liquid flowing in the pipeline flows back into the interior of the transfer pipe 21 from the lower end of the transfer pipe 21, causing the liquid flow path to branch and affecting the flow path, thereby allowing the liquid to flow stably along the main pipeline.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4 The top cover 3 has a rotating rod 31 and a guide rod 32 that are fixedly connected inside. The outer wall of the rotating rod 31 is threaded to the inside of the sealing plate 321, and the outer wall of the guide rod 32 is abutted against and slidably connected to the inner wall of the sealing plate 321. A mounting frame 4 that is fixedly connected is provided on one side wall of the top cover 3. One end of the rotating rod 31 extends into the mounting frame 4 and is rotatably connected to the inner wall of the mounting frame 4. A worm gear 311 that is fixedly connected is sleeved on the outer wall of the rotating rod 31 inside the mounting frame 4. A driving rod 41 that is rotatably connected is provided inside the mounting frame 4. A worm gear 411 that is fixedly connected is sleeved on the outer wall of the driving rod 41, and the worm gear 411 and the worm wheel 311 are meshed together.

[0030] It should be noted that the rotating rod 31 is driven by the meshing of the worm gear 311 and the worm 411. In subsequent use, the self-locking characteristics of the two can prevent the rotating rod 31 from rotating randomly during use, which would cause the sealing plate 321 and the adapter frame 22 to loosen, thereby reducing the sealing effect of the sealing plate 321 on the connection part of the adapter frame 22.

[0031] The working principle of the novel flow control device provided by this utility model is as follows:

[0032] When using this device, it can be installed in the required pipeline through the adapter 211 in the device. After the installation of the device is completed, the flow rate of the liquid flowing in the corresponding pipeline can be controlled by the flow control valve 1.

[0033] During later use, when the flow control valve 1 needs to be inspected and maintained, the drive rod 41 can be rotated first. The rotating drive rod 41 will drive the worm 411 on the outer wall to rotate. At this time, the rotating worm 411 can drive the rotating rod 31 to rotate through the meshing with the external worm wheel 311. The rotating rod 31 will drive the sealing plate 321 to move towards the inside of the adapter frame 22 through the threaded structure on the outer wall, thereby releasing the blockage of the side wall connection part of the adapter frame 22. At the same time, the gate valve 212 outside the adapter pipe 21 can be closed, thereby guiding the flow path of the pipeline into the adapter pipe 21.

[0034] After the pipeline flow path is changed, the flow control valve 1 can be removed from the corresponding gate valve 212, so that the pipeline can still flow smoothly when the flow control valve 1 is under maintenance, avoiding the impact on the pipeline flow state during the maintenance process.

[0035] Furthermore, during use, staff can control the opening state of the sealing plate 321 as needed, allowing the liquid flowing in the pipeline to flow into the adapter frame 22 and its internal sampling tube 221. This allows staff to collect liquid samples while the liquid is flowing normally in the pipeline, making it more convenient for staff to sample the liquid when fluid testing is required, thereby improving the user experience of this device.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
