[0002] A fluid control device is a fluid parameter adjustment device used in a pipeline system, which is intended to adjust parameters such as pressure and flow of the fluid in the pipeline. A traditional fluid control device usually includes a regulating part and a control part. The regulating part is installed in the pipeline, and the control part is arranged outside the pipeline. The control part is used to control the regulating part to operate with a certain parameter so that the regulating part can adjust parameters such as pressure and flow of the fluid in the pipeline. In the prior art, the installation method of the traditional fluid control device is relatively complicated. The installer first needs to process an opening on the pipe wall of the pipeline, and then pass the regulating part through the opening and install it in the pipeline, and finally install the control part on the outer wall of the pipeline to complete the installation of the traditional fluid control device. The installation method of the traditional fluid control device is not only relatively complicated, but also not conducive to improving the convenience of installation for the installer; on the other hand, the installation method of the traditional fluid control device will damage the pipe wall of the pipeline, greatly reducing the sealing effect of the pipeline.

[0035] refer to Figures 1 to 4 According to an embodiment of the utility model, the pipeline fluid control device comprises:

[0036] Sealing cylinder 100;

[0037] A first end cover 110 and a second end cover 120, wherein the first end cover 110 is provided with a first through hole, and the second end cover 120 is provided with a second through hole, and the first end cover 110 and the second end cover 120 are connected via a sealing cylinder 100, so that both the first through hole and the second through hole are communicated with the sealing cylinder 100, and an end of the first end cover 110 away from the sealing cylinder 100 is used to be connected to an upstream pipeline, and an end of the second end cover 120 away from the sealing cylinder 100 is used to be connected to a downstream pipeline, so that a passage for fluid flow is formed between the upstream pipeline, the first through hole, the sealing cylinder 100, the second through hole and the downstream pipeline;

[0038] The paddle 200 is rotatably disposed in the sealing cylinder 100;

[0039] The stator assembly 400 and the rotor assembly 300, the rotor assembly 300 is arranged in the sealing tube 100, the rotor assembly 300 is connected to the blade 200, the stator assembly 400 is arranged on the outer wall of the sealing tube 100, the stator assembly 400 and the rotor assembly 300 are magnetically connected, and the stator assembly 400 is used to drive the rotor assembly 300 to rotate so that the blade 200 can rotate and act on the fluid in the sealing tube 100.

[0040] It can be understood that the ends of the first end cap 110 and the second end cap 120 away from the sealing cylinder 100 are respectively used to connect with the upstream pipeline and the downstream pipeline, so that the upstream pipeline, the first through hole on the first end cap 110, the sealing cylinder 100, the second through hole on the second end cap 120 and the downstream pipeline form a passage for fluid flow, thereby allowing the fluid in the upstream pipeline to flow into the downstream pipeline through the first through hole, the sealing cylinder 100 and the second through hole. The stator assembly 400 is magnetically connected to the rotor assembly 300, and the rotor assembly 300 is connected to the blade 200. When the pressure and flow rate of the fluid in the pipeline need to be adjusted, the stator assembly 400 can drive the rotor assembly 300 to rotate forward and reverse, and control the rotation speed of the rotor assembly 300, thereby realizing the control of the direction and speed of the blade 200. The rotating blade 200 can act on the fluid in the sealing tube 100. By controlling the direction and rotation speed of the blade, the force of the blade 200 on the fluid can be changed. For example, the forward rotation of the blade 200 will increase the flow rate of the fluid, and the reverse rotation will reduce the flow rate of the fluid. The faster the rotation speed of the blade, the faster the flow rate of the fluid, and the slower the rotation speed of the blade 200, the lower the flow rate of the fluid, thereby achieving precise control of the pressure and flow rate of the fluid in the upstream pipeline and the downstream pipeline. When the pipeline fluid control device needs to be installed, it is only necessary to connect the first end cover 110 to the upstream pipeline and the second end cover 120 to the downstream pipeline to complete the installation of the pipeline fluid control device, thereby improving the convenience of installation of the pipeline fluid control device. The installation method of the pipeline fluid control device does not need to process an opening on the pipe wall of the pipeline, thereby avoiding damage to the pipe wall of the pipeline, ensuring the sealing of the pipeline, and thereby helping to improve the sealing effect of the pipeline. On the other hand, the stator assembly 400 in the pipeline fluid control device is completely placed outside the sealing cylinder 100, so that the direction and speed of the blades 200 and the rotor assembly 300 can be precisely adjusted without any physical damage to the sealing cylinder 100, thereby ensuring the sealing performance of the sealing cylinder 100.

[0041] It should be explained that in the present invention, the pipeline is divided into an upstream pipeline and a downstream pipeline. The pipeline on the side where the fluid flows into the pipeline fluid control device is the upstream pipeline, and the pipeline on the side where the fluid flows out of the pipeline fluid control device is the downstream pipeline. In the present invention, the second end cover 120 can also be connected to the upstream pipeline, and the first end cover 110 can also be connected to the downstream pipeline. The axis of the first through hole on the first end cover 110 coincides with the axis of the sealing cylinder 100, and the axis of the second through hole on the second end cover 120 coincides with the axis of the sealing cylinder 100.

[0042] In the present invention, the stator assembly 400 is composed of electromagnetic coils, external seals, power supplies, and frequency converters. When the stator assembly 400 is working, a high-frequency rotating magnetic field is generated, and the magnetic field passes through the sealing cylinder 100 and acts on the magnetic rotor assembly 300. The intensity and rotation frequency of the high-frequency rotating magnetic field can be continuously adjusted, so that the stator assembly 400 can drive the rotor assembly 300 to rotate, and can control the direction and speed of the rotor assembly 300.

[0043] As an embodiment of the utility model, the pipeline fluid control device also includes a cover tube, which is sleeved on the sealing tube 100, and the two ends of the cover tube are respectively connected to the first end cover 110 and the second end cover 120. It can be understood that the cover tube is sleeved on the sealing tube 100, so that the stator assembly 400 and the sealing tube 100 are arranged in the cover tube. The cover tube plays a protective role, preventing the external environment from polluting or damaging the stator assembly 400 and the sealing tube 100, which is conducive to extending the service life of the stator assembly 400 and the sealing tube 100. In the utility model, the axis of the cover tube coincides with the axis of the sealing tube 100.

[0044] refer to Figure 1 and Figure 2 , a first sealing member 130 is provided between the first end cover 110 and the sealing cylinder 100, and a second sealing member 140 is provided between the second end cover 120 and the sealing cylinder 100. It can be understood that the first sealing member 130 can seal the gap between the first end cover 110 and the sealing cylinder 100, and the second sealing member 140 can seal the gap between the second end cover 120 and the sealing cylinder 100, further improving the sealing performance of the sealing cylinder 100. As an embodiment of the utility model, the first sealing member 130 is a first sealing ring, the second sealing member 140 is a second sealing ring, a first annular groove is provided on the first end cover 110, a second annular groove is provided on the second end cover 120, the first sealing ring is provided in the first annular groove, and the second sealing ring is provided in the second annular groove.

The axis of the rotating shaft 220 coincides with the axis of the sealing cylinder 100. The rotating shaft 220 is arranged in the sealing cylinder 100. The two ends of the rotating shaft 220 are respectively rotatably connected to the first support member 210 and the second support member. The blade 200 is connected to the rotating shaft 220. It can be understood that when the stator assembly 400 drives the rotor assembly 300 to rotate, the rotor assembly 300 drives the blade 200 and the rotating shaft 220 to rotate. Since the first support member 210 and the second support member are respectively connected to the hole walls of the first through hole and the second through hole, the first support member 210 and the second support member remain stationary. The first support member 210 and the second support member play a supporting and connecting role, so that the blade 200, the rotating shaft 220 and the rotor assembly 300 can rotate smoothly.

[0046] refer to Figure 1 The pipeline fluid control device also includes two oil-free lubricating bearings 230, and both ends of the rotating shaft 220 are rotatably connected to the first support member 210 and the second support member respectively through the oil-free lubricating bearings 230. It can be understood that the oil-free lubricating bearings 230 are a type of bearing that uses a non-traditional lubrication method, and they do not rely on traditional lubricating oil or grease to reduce friction and wear. The design of the oil-free lubricating bearings 230 can prevent the lubricating oil or grease from contaminating the fluid in the pipeline, and the oil-free lubricating bearings 230 do not require frequent maintenance. Specifically, the oil-free lubricating bearings 230 are ceramic self-lubricating bearings, which are a type of bearing that combines ceramic materials and self-lubricating technology. Ceramic self-lubricating bearings use ceramics as the base material of the bearing, and embed self-lubricants on the surface or inside to achieve the self-lubricating effect of the bearing. The ceramic material of the ceramic self-lubricating bearing has excellent high temperature resistance and corrosion resistance, and can be in a high temperature and high-speed fluid environment for a long time and operate normally.

[0047] refer to Figure 4The first support member 210 includes a first mounting tube 211 and a plurality of first mounting rods 212. The axis of the first mounting tube 211 coincides with the axis of the sealing tube 100. The plurality of first mounting rods 212 are arranged in a circular array on the outer wall of the first mounting tube 211 along the axis of the first mounting tube 211. The first mounting tube 211 is connected to the hole wall of the first through hole through the plurality of first mounting rods 212. The first mounting tube 211 is used for one end of the rotating shaft 220 to pass through, so that one end of the rotating shaft 220 can be rotatably connected to the inner wall of the first mounting tube 211. The first support member 210 and the second support member have the same structure. The second support member includes a second mounting cylinder and a plurality of second mounting rods. The axis of the second mounting cylinder coincides with the axis of the sealing cylinder 100. The plurality of second mounting rods are arranged on the outer wall of the second mounting cylinder along the axis of the second mounting cylinder. The second mounting cylinder is connected to the hole wall of the second through hole through the plurality of second mounting rods. The second mounting cylinder is used for the other end of the rotating shaft 220 to pass through so that the other end of the rotating shaft 220 can be rotatably connected to the inner wall of the second mounting cylinder. Specifically, one oil-free lubricating bearing 230 is arranged in the first mounting cylinder 211, and the other oil-free lubricating bearing 230 is arranged in the second mounting cylinder.

[0048] refer to Figure 1 , a guide cover 213 is provided on the side away from each other of the first support member 210 and the second support member, and the axis of the guide cover 213 coincides with the axis of the sealing tube 100. It can be understood that the guide cover 213 can help guide the fluid so that the fluid can flow better over the surface of the blade 200, thereby increasing the rotation efficiency of the blade 200. On the other hand, the guide cover 213 can reduce the turbulence and eddy current generated by the fluid on the blade 200, reduce the energy loss of the rotation of the blade 200, improve the power transmission efficiency of the stator assembly 400, and reduce the energy consumption of the pipeline fluid control device.

[0049] refer to Figure 1 and Figure 2 , the rotor assembly 300 includes a magnetic cylinder 310, the axis of the magnetic cylinder 310 coincides with the axis of the sealing cylinder 100, the blade 200 is disposed in the magnetic cylinder 310, the outer end of the blade 200 is connected to the magnetic cylinder 310, and the magnetic cylinder 310 is magnetically connected to the stator assembly 400. It can be understood that the magnetic cylinder 310 can be magnetically connected to the stator assembly 400, so that the stator assembly 400 can drive the magnetic cylinder 310 to rotate, and then the magnetic cylinder 310 can drive the blade 200 to rotate. As an embodiment of the present utility model, the rotor assembly 300 includes a transfer cylinder 320, the axis of the transfer cylinder 320 coincides with the axis of the sealing cylinder 100, the blade 200 is disposed in the transfer cylinder 320, the outer end of the blade 200 is connected to the transfer cylinder 320, and the magnetic cylinder 310 is sleeved on the outer wall of the transfer cylinder 320 and connected to the transfer cylinder 320. It can be understood that the adapter tube 320 plays a connecting role, so that the blade 200 is connected to the magnetic tube 310 through the adapter tube 320 .

[0050] As an embodiment of the present invention, the blade 200 is magnetic, so that the blade 200 can be magnetically connected to the stator assembly 400. It can be understood that the magnetic blade 200 can be magnetically connected to the stator assembly 400, so that the stator assembly 400 can also drive the blade 200 to rotate, that is, the stator assembly 400 can drive the blade 200 and the rotor assembly 300 to rotate at the same time, which is conducive to improving the power transmission efficiency of the stator assembly 400.

[0051] In the present invention, if the pipeline fluid control device needs to be maintained, the maintenance personnel can first remove the first end cover 110 and the second end cover 120 from the cover tube and the sealing tube 100, and then remove the sealing tube 100. At this time, the maintenance personnel can maintain the stator assembly 400, the rotor assembly 300 and the blade 200, thereby improving the convenience of maintaining the pipeline fluid control device. On the other hand, the number of pipeline fluid control devices in the present invention can be multiple, and multiple pipeline fluid control devices can be arranged on the pipeline in a series or parallel manner.
