Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balancing valves, in particular to a double-core coaxial dynamic balancing valve. Background Art

[0002] A dual-core coaxial dynamic balancing valve is a fluid control valve with a unique design that achieves dynamic balancing and precise flow control. This valve is commonly used in applications requiring precise fluid control, such as water supply systems, HVAC systems, and industrial process control. The "dual-core" design of this valve refers to the dual-axis structure of the valve stem and valve core, which enables dynamic flow balance while controlling the valve's opening and closing. By adjusting the valve core position, the fluid flow can be precisely controlled, achieving balanced and stable fluid control.

[0053] The connection slot 204a facilitates installation of the filter housing 204b. The filter plate 204c installed in the filter housing 204b can filter impurities, and the handle 204d facilitates removal of the filter housing 204b from the connection slot 204a.

[0054] Specifically, the filter element 204 further includes a storage tank 204e and a sealing plug 204f. The storage tank 204e is opened in the inner cavity of the filter shell 204b, and the sealing plug 204f is installed on the top of the filter shell 204b.

[0055] The storage slot 204e is opened between the two filter plates 204c, which makes it convenient to pour purification materials such as activated carbon into the filter shell 204b, thereby improving the liquid purification effect, and the sealing plug 204f is convenient for blocking the slot to prevent the material from flowing out.

[0058] During use, first connect the flange 206 to other pipes, then align the fixed plate 201 with the positioning shell 103a through the tooth plate 202 and insert it. At this time, the sealing gasket 105 is in contact with the sealing groove 104. Then twist the torsion block 103d to drive the screw 103c to make the card plate 103b move horizontally. When the card plate 103b moves, it will drive the slider 103h to move within the inner cavity of the slide groove 103i, and at the same time stretch the second spring 103g. Then, the card plate 103b is in contact with the surface of the tooth plate 202 to position and install it. However, when the liquid is transported, it will pass through the filter plate 204c to filter out impurities. At the same time, the activated carbon material in the storage tank 204e can be used to purify the water.
