Description

Technical Field

[0001] The utility model relates to the technical field of flow regulating valves, in particular to a flow regulating valve for an air separation device. Background Art

[0002] Flow regulating valve, also known as self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, flow balancing valve, is an intuitive and simple flow regulating control device, and is also a common accessory for air separation devices.

[0003] As disclosed in publication number CN213088791U, a gas flow regulating valve includes a valve body, a pneumatic device, and a valve cover. The valve body is fixedly connected to the valve cover by bolts. The output end of the pneumatic device is connected to a valve stem in a transmission manner. The valve stem is fixedly connected to a limiting rod. The end of the valve stem is fixedly connected to a valve core. The valve core is fixedly connected to a fixed block. A guide sleeve is provided inside the valve cover. In the present utility model, since the output end of the pneumatic device is connected to the valve stem in a transmission manner, the valve stem is driven to move in the vertical direction. Since the limiting rod is fixedly connected to the side wall of the valve stem, the top and bottom ends of the limiting rod are elastically connected to the first housing through a spring. The limiting rod abuts against the inner surface wall of the first housing. In the case of a large flow rate, the valve core can be prevented from shifting. The guide sleeve can prevent the valve core from shifting in the horizontal direction, which solves the problem that the valve core is easily shifted when the flow rate is large.

[0004] This patent can prevent the valve core from shifting when the flow rate is large, and the guide sleeve can prevent the valve core from shifting in the horizontal direction, solving the problem that the valve core is easily shifted when the flow rate is large. However, the existing flow control valve is not equipped with a filter component, and the air separation device may contain tiny impurities, particles or moisture. These impurities are easily deposited in narrow parts such as the throttle port and the guide when passing through the flow control valve, causing the valve to be blocked. Therefore, we propose a new flow control valve for an air separation device. Utility Model Content

[0008] Furthermore, the moving block is threadedly connected to the bidirectional screw through the threaded hole, and the filter screen is slidably connected to the filter box through the mounting groove.

[0009] Furthermore, the position and size of the plug block match the position and size of the socket, and a snap-fit ​​connection is formed between the plug block and the socket.

[0010] Furthermore, a sealing ring is connected to the top surface of the filter screen, and the outer surfaces on both sides of the filter screen are in contact with the inner walls on both sides of the installation groove.

[0011] Furthermore, the moving block has a rectangular shape.

[0012] Furthermore, outer surfaces of the air inlet and the air outlet are both connected with protection components, and the protection components include thread grooves.

[0013] Furthermore, a thread block is connected inside the thread groove, a handle is connected to one side of the thread block, and a threaded connection is formed between the thread block and the thread groove.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1 - Figure 4As shown, the utility model provides a flow control valve for an air separation device, comprising a control valve body 1, one side of the control valve body 1 is connected to an air inlet 2, the other side of the control valve body 1 is connected to an air outlet 3, the side of the control valve body 1 close to the air inlet 2 is connected to a filter assembly 4, the filter assembly 4 comprises a connecting block 401, the top of the connecting block 401 is connected to a filter box 402, the filter box 402 is provided with a mounting groove 403, a filter screen 404 is provided inside the mounting groove 403, a bidirectional screw 405 is plugged into the inside of the connecting block 401, the two ends of the bidirectional screw 405 are respectively connected to a bearing 406 and a handle 407, the surface of the bidirectional screw 405 is symmetrically connected to two groups of moving blocks 408, and the moving block 408 is provided with a threaded hole 409 , the inner sides of the two groups of moving blocks 408 are connected with plug blocks 410, and the bottoms of both sides of the filter screen 404 are provided with plug holes 411. The two-way screw 405 and the handle 407 are fixedly connected, and the two-way screw 405 and the bearing 406 are rotatably connected. The moving block 408 is threadedly connected with the two-way screw 405 through the threaded hole 409, and the filter screen 404 is slidably connected with the filter box 402 through the mounting groove 403. The position and size of the plug block 410 match the position and size of the plug hole 411, and the plug block 410 and the plug hole 411 are snap-fitted. The top surface of the filter screen 404 is connected with a sealing ring, and the outer surfaces of both sides of the filter screen 404 are in contact with the inner walls of both sides of the mounting groove 403. The outer shape of the moving block 408 is rectangular.

[0026] The effect achieved by the entire embodiment 1 is that, when the regulating valve body 1 is opened, air will enter the regulating valve body 1 through the air inlet 2, and the filter screen 404 can effectively filter impurities and dust in the air. When the filter screen 404 needs to be removed and cleaned after long-term use, the handle 407 can be rotated in the reverse direction, so that the handle 407 drives the bidirectional screw 405 to rotate in the reverse direction. The bearing 406 can improve the stability of the bidirectional screw 405 when rotating. When the bidirectional screw 405 rotates in the reverse direction, it will also rotate with the two sets of moving blocks 408 through the threaded hole 409, thereby making The two groups of moving blocks 408 can move to both sides at the same time by rotating the threads, and drive the plug block 410 to be pulled out from the socket 411, and then the filter screen 404 is pulled out from the installation groove 403 for cleaning.

When the regulating valve body 1 is not installed and used, the threaded block 502 can be installed in the threaded groove 501 to achieve the closure of the regulating valve body 1 and the protection of the regulating valve body 1.
