Technical Field

[0001] The utility model relates to the technical field of valve devices, in particular to a valve ball. Background Art

[0002] A valve is a mechanical device that controls the flow of a fluid. It can be used to control the opening and closing of a fluid channel and to adjust the flow rate of the fluid in the channel. The valve can usually control the flow of the fluid by rotating or pushing and pulling. The valve ball is a common type of valve with a low risk of fluid leakage and is often used in fluid transmission scenarios with high sealing performance.

[0003] The existing technology often has the following problems when used:

[0004] Adjusting the water outlet flow rate of the valve ball usually requires replacing the outlet pipe at the outlet end, which makes the adjustment of the water outlet flow rate of the valve ball inconvenient; in addition, a fixed filter is usually required at the water inlet end of the valve ball to filter impurities in the water. However, the disassembly operation of the filter structure is relatively cumbersome, which makes the maintenance efficiency of the filter structure in the valve ball low. Utility Model Content

[0014] Furthermore, a traction paddle is fixedly connected to the end of the plug-in rod away from the mounting ring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The water outlet speed regulating assembly of the utility model can drive the double-channel regulating pipe to rotate by rotating the regulating collar, so that the first water outlet channel or the second water outlet channel on the double-channel regulating pipe is connected to the water outlet pipe correspondingly, so as to change the inner diameter size of the water outlet channel of the valve ball, thereby conveniently adjusting the water outlet flow rate of the valve ball;

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a valve ball, including a valve ball 1 and a filter 2, a water outlet speed regulating assembly and a filter assembly and disassembly assembly: the water inlet end of the valve ball 1 is fixedly connected to the water inlet pipe 3, and the water outlet end of the valve ball 1 is fixedly connected to the water outlet pipe 4; the water outlet speed regulating assembly includes an adjusting collar 5 rotatably connected to the outer wall of the water outlet pipe 4, a knob 14 is fixedly connected to the outer wall of the adjusting collar 5, and the end of the adjusting collar 5 away from the valve ball 1 is fixedly connected to a double-channel speed regulating pipe 6, the axial side walls of the water outlet pipe 4 and the double-channel speed regulating pipe 6 are fixedly connected with sealing gaskets, and the outer wall of the water outlet pipe 4 is fixedly connected with a limiting protrusion 12. A strip-shaped limiting hole 13 is provided on the adjusting collar 5, and the limiting protrusion 12 matches the strip-shaped limiting hole 13. The cooperation of the limiting protrusion 12 and the strip-shaped limiting hole 13 can fully limit the rotation of the adjusting collar 5 and the dual-channel speed regulating tube 6, and the strip-shaped limiting hole 13 can limit the rotation of the adjusting collar 5, so that the adjusting collar 5 can only rotate 180 degrees relative to the water outlet pipe 4. A first water outlet channel 10 and a second water outlet channel 11 are provided on the dual-channel speed regulating tube 6. The inner diameter of the first water outlet channel 10 is equal to the inner diameter of the water outlet pipe 4, and the inner diameter of the second water outlet channel 11 is smaller than the inner diameter of the first water outlet channel 10.

[0025] The adjusting collar 5 is driven to rotate by rotating the knob 14, so that the double-channel speed regulating tube 6 at the end of the adjusting collar 5 is synchronously rotated 180 degrees, so that the first water outlet channel 10 or the second water outlet channel 11 on the double-channel speed regulating tube 6 is correspondingly connected to the water outlet pipe 4 to change the inner diameter size of the water outlet channel of the valve ball. According to the Bernoulli principle, without considering the compressibility of the fluid, the narrower the channel through which the fluid passes, the faster its flow rate. Therefore, the water outlet flow rate of the valve ball 1 can be adjusted by the first water outlet channel 10 and the second water outlet channel 11 with unequal inner diameters.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the filter assembly includes a mounting ring 7 fixedly connected to the filter 2, a sealing gasket is fixedly connected to the outer surface of the mounting ring 7, the outer diameter of the sealing gasket is larger than the inner diameter of the water inlet pipe 3, two plug-in rods 8 are fixedly connected to the mounting ring 7, two mounting slots 9 are provided on the axial side wall of the water inlet pipe 3, the plug-in rods 8 match the mounting slots 9, and a traction paddle 15 is fixedly connected to the end of the plug-in rod 8 away from the mounting ring 7;

[0027] Connect the mounting ring 7 and the filter screen 2 into the water inlet pipe 3 so that the plug-in rod 8 on the mounting ring 7 corresponds to the mounting slot 9 on the water inlet pipe 3, so that the mounting ring 7 and the filter screen 2 can be quickly installed and fixed in the water inlet pipe 3. When the filter screen 2 is disassembled and removed, the mounting ring 7 can be pulled by pulling the traction paddle 15 to separate the plug-in rod 8 from the mounting slot 9, so that the mounting ring 7 can be quickly removed from the water inlet pipe 3, which is beneficial to improving the efficiency of disassembly and maintenance of the filter screen 2.

[0028] The detailed working process of the utility model is as follows:

[0029] 1. When in use, if the water outlet flow rate of the valve ball 1 needs to be adjusted, the knob 14 can be turned to drive the adjusting collar 5 to rotate, so that the double-channel speed regulating tube 6 at the end of the adjusting collar 5 rotates 180 degrees synchronously, so that the first water outlet channel 10 or the second water outlet channel 11 on the double-channel speed regulating tube 6 is connected to the water outlet pipe 4 correspondingly, so as to change the inner diameter of the water outlet channel of the valve ball, thereby facilitating the adjustment of the water outlet flow rate of the valve ball 1;

[0030] 2. When the filter 2 is installed and used, the mounting ring 7 and the filter 2 can be directly connected to the water inlet pipe 3, so that the plug-in rod 8 on the mounting ring 7 corresponds to the mounting slot 9 on the water inlet pipe 3, so that the mounting ring 7 and the filter 2 can be quickly installed and fixed in the water inlet pipe 3. When the filter 2 is disassembled and removed, the mounting ring 7 can be pulled by pulling the traction paddle 15 to separate the plug-in rod 8 from the mounting slot 9, so that the mounting ring 7 can be quickly removed from the water inlet pipe 3, which is beneficial to improving the disassembly and maintenance efficiency of the filter 2.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
