[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a controllable flow filter valve includes a water cup 1 and a valve body 31 installed on the top of the water cup 1. The water cup 1 has an inner cavity 11. In addition, a water outlet 12 is provided at the bottom of the water cup 1. The water outlet 12 connects the outside with the inner cavity 11. A filter element 22 located in the inner cavity 11 is fixedly installed at the bottom of the valve body 31. The valve body 31 has a valve cavity 30. The valve cavity 30 is provided with an adjusting component 4 with adjustable flow. The adjusting component 4 includes a mounting plate 42 and an adjusting cylinder 41 mounted on the mounting plate 42. The adjusting cylinder 41 is provided with an adjusting hole 413. The mounting plate 42 is provided with a matching hole 421 matching with the adjusting hole 413. The mounting plate 42 is fixedly arranged in the valve cavity 30. A sealing member 5 is installed on the mounting plate 42. The sealing member 5 is sealed and matched with the valve cavity 30.

[0021] A further mounting plate 42 is fixedly mounted on the valve body 31 by means of bolts.

[0022] A connecting rod 21 is connected to the valve body 31. The connecting rod 21 is a double-headed threaded rod. The valve body 31 has a threaded hole that is threadedly matched with the connecting rod 21. The lower end of the connecting rod 21 is connected to a water-shedding plate 23. The water-shedding plate 23 is located below the filter element 22. The water-shedding plate 23 is threadedly installed on the other end of the connecting rod 21. Through threaded matching, the water-shedding plate 23 can be more conveniently replaced when it is damaged.

[0023] A connecting column 414 and a positioning column 422 are respectively provided between the adjusting cylinder 41 and the mounting plate 42. The positioning column 422 has a positioning hole 423 for the connecting column 414 to cooperate with and install. The adjusting cylinder 41 is installed in the positioning hole 423 through the connecting column 414. The connecting column 414 and the positioning hole 423 are coaxially arranged, and the adjusting cylinder 41 rotates around the axis of the connecting column 414.

[0024] In the present application, the adjusting hole 413 and the matching hole 421 have the same shape, so that the adjusting hole 413 and the matching hole 421 on the adjusting cylinder 41 can be matched with each other by rotating the adjusting cylinder 41. When the flow rate is maximum, the matching hole 421 and the adjusting hole 413 completely overlap, so that the flow rate is adjusted to the maximum, and there is always an overlapping part between the adjusting hole 413 on the adjusting cylinder 41 and the matching hole 421 on the mounting plate 42, so that the valve chamber 30 will never be in a closed state.

[0025] The end of the regulating cylinder 41 is provided with a connecting plate 411 , and the valve body 31 is provided with a matching groove 311 , and the matching groove 311 is used for positioning and installing the connecting plate 411 .

[0026] A mounting groove 412 is provided on the connecting plate 411, and the mounting groove 412 is used to install a sealing ring. By installing the sealing ring in the mounting groove 412, not only a sealing effect is achieved, but also the sealing ring can be squeezed when an external connecting pipe or a water pump or an air pump is connected, thereby causing the sealing ring to deform, thereby increasing the friction between the sealing ring and the external pipe and the connecting plate 411, so that relative rotation does not occur between the regulating cylinder 41 and the mounting plate 42, thereby achieving fixedness after flow regulation.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
