[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. A concentrated water regulating valve structure capable of accurately adjusting flow and preventing clogging. During the drainage process of the regulating valve body, the cylindrical rod moves in hole one, making it difficult for scale to form in hole one.

[0023] 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.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A concentrated water regulating valve structure capable of accurately regulating flow and preventing clogging, comprising a regulating valve body 1, a valve core assembly 2 is arranged at the inner upper end of the regulating valve body 1, the valve core assembly 2 is composed of a valve core body 4, a cylindrical rod 5 and a cylindrical boss 6, the cylindrical rod 5 is integrally formed at the middle of the top end of the valve core body 4, and the cylindrical boss 6 is integrally formed at the middle of the bottom end of the valve core body 4; a second hole 7 is also arranged at the inner middle of the regulating valve body 1, the valve core body 4 and the cylindrical boss 6 are movably arranged inside the second hole 7, a connected hole 1 8 is arranged at the upper end of the regulating valve body 1 located at the second hole 7, and the cylindrical rod 5 is movably connected to the hole 1 8; the outer connection between the valve core body 4 and the cylindrical rod 5 matches the inner connection between the hole 1 8 and the hole 2 7;

[0026] In this embodiment, since the cylindrical rod 5 moves in the hole 8 during the drainage process of the regulating valve body 1, it is difficult for scale to form in the hole 8. When foreign matter enters the hole 8, the dredging effect automatically formed by the movement of the cylindrical rod 5 in the hole 8 makes it difficult for the foreign matter to stay in the hole 8 and is easy to be discharged, thereby preventing blockage.

[0027] like Figure 1 and Figure 2 As shown, an adjusting assembly 3 is provided at the lower end of the inner part of the regulating valve body 1, and the adjusting assembly 3 is composed of an adjusting nut 9, a third hole 10 and a fourth hole 11. A third hole 10 is horizontally provided at the upper end of the inner part of the adjusting nut 9, and a fourth hole 11 is vertically provided below the third hole 10 of the adjusting nut 9, and the fourth hole 11 is connected with the third hole 10, and a connected square hole 12 is provided below the fourth hole 11 of the adjusting nut 9; the adjusting nut 9 is threadedly connected with the inner wall below the second hole 7, and a spring 13 is provided between the outer part of the top end of the adjusting nut 9 and the outer part of the cylindrical boss 6;

[0028] In this embodiment, the regulating valve body 1 is connected to the adjusting nut 9 by threads, and because the thread length of the regulating valve body 1 is longer than that of the adjusting nut 9, the depth of the adjusting nut 9 in the regulating valve body 1 is controlled to be different, so that the compression elastic force generated by the spring 13 between the valve core assembly 2 and the adjusting assembly 3 is different, so that the distance that the valve core assembly 2 moves downward under the same water pressure of the hole 8 is also different, and thus the drainage flow rate is also different, thereby achieving the purpose of accurately adjusting the water output.

[0029] Working principle: the adjusting nut 9 is connected to the regulating valve body 1 through a threaded structure, wherein the length of the threaded hole of the regulating valve body 1 is longer than the length of the thread on the adjusting nut 9, a cylindrical rod 5 is provided on the valve core body 4, after the valve core assembly 2 is installed in the hole 2 7, the cylindrical rod 5 is inserted into the hole 1 8, a spring 13 is provided between the valve core assembly 2 and the adjusting assembly 3, one end of the spring 13 is inserted into the cylindrical boss 6, and the other end is inserted into the adjusting nut 9, under the action of the spring 13, in the initial state, the outer connection between the valve core body 4 and the cylindrical rod 5 is tightly attached to the inner connection between the hole 1 8 and the hole 2 7, a hole 3 10, a hole 4 11 and a square hole 12 are provided on the adjusting nut 9, the hole 3 10, the hole 4 11 and the square hole 12 are connected, and the square hole 12 can be conveniently used with a square tool to rotate and adjust the adjusting nut 9; when water enters the hole 1 8, the valve core assembly 2 moves downward under the push of water pressure, and the outer connection between the valve core body 4 and the cylindrical rod 5 is connected to the hole 1 8 and the hole 2 7 increases accordingly, wherein the greater the water pressure, the greater the downward movement distance of the valve core assembly 2, the greater the distance between the outer connection of the valve core body 4 and the cylindrical rod 5 and the inner connection of the hole 1 8 and the hole 2 7, and the incoming water passes through the hole 1 8, the hole 2 7, the hole 3 10, the hole 4 11 in sequence, and then is discharged from the square hole 12; when the water pressure at the water inlet end of the hole 1 8 decreases, the valve core assembly 2 moves upward, and the distance between the outer connection of the valve core body 4 and the cylindrical rod 5 and the inner connection of the hole 1 8 and the hole 2 7 decreases accordingly, and when the pressure at the water inlet end disappears, the valve core assembly 2 returns to its initial state; the distance between the adjusting assembly 3 and the valve core assembly 2 can be controlled by rotating the adjusting nut 9 through the square hole 12 on the adjusting nut 9 with a square tool, and the smaller the distance, the greater the elastic force generated by the spring 13 between the adjusting assembly 3 and the valve core assembly 2. Under the same water pressure, the smaller the distance the valve core assembly 2 moves, the smaller the flow rate of water discharged from the regulating valve body 1, and vice versa.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
