DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the drawings and specific embodiments. The illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but not to limit the present utility model.

[0020] As Figure 1 、 2As shown: The utility model includes a one-way valve body assembly and a flow rate regulating assembly. The flow rate regulating assembly is arranged inside the one-way valve body assembly, and the flow rate regulating assembly is arranged at the water outlet of the one-way valve body assembly.

[0021] Furthermore, the one-way valve body assembly includes a valve housing 1, a water inlet 2, a drain outlet 12, a valve core 3, a valve core moving telescopic rod 4, a fixed water guide disc 5, a valve core return spring 6, and a valve body cover 10. The water inlet 2 is arranged at the lower section inside the valve housing 1. The lower end of the valve core 3 contacts the outlet of the water inlet 2. The fixed water guide disc 5 is fixedly arranged at the middle section inside the valve housing 1. The lower end of the valve core moving telescopic rod 4 is fixedly connected to the middle section of the valve core 3. The valve core return spring 6 is arranged between the fixed water guide disc 5 and the valve core 3. The drain outlet 12 is arranged at the upper section of the valve housing 1. The fixed water guide disc 5 is provided with a through hole. The flow rate regulating assembly is arranged between the outside of the fixed water guide disc 5 and the inlet of the drain outlet 12. The valve body cover 10 is connected to the upper opening position of the valve housing 1.

[0022] Specifically, the flow rate regulating assembly includes a rotating water guide disc 8, an adjusting handle 11, and a water guide disc driving shaft 13. The rotating water guide disc 8 is provided with a flow rate regulating hole 9. The shape of the flow rate regulating hole 9 corresponds to the position of the through hole on the fixed water guide disc 5. The lower end surface of the rotating water guide disc 8 is in contact with the upper end surface of the fixed water guide disc 5. The upper end of the rotating water guide disc 8 is fixedly connected to the lower end of the water guide disc driving shaft 13. The upper end of the water guide disc driving shaft 13 passes through the valve body cover 10. The adjusting handle 11 is connected to the position of the water guide disc driving shaft 13 exposed outside the valve body cover 10.

[0023] As an improvement, a valve core limiting block 7 is connected to the upper end of the valve core moving telescopic rod 4, and the diameter of the valve core limiting block 7 is larger than the diameter of the valve core moving telescopic rod 4.

[0024] The working principle of the utility model is as follows:

[0025] When the utility model is in use, water flow is introduced from the water inlet 2. When the water pressure of the water flow enters the water inlet 2, the pressure of the water flow is greater than the elastic force of the valve core return spring 6, and the valve core 3 can be pushed open to the position at the inlet of the water inlet 2, thereby opening the valve core 3. The water flow passes through the through holes and flow adjustment holes 9 of the fixed water guide disc 5 and then flows out from the drain port 12. When the water pressure at the water inlet 2 is low or the water flows back, the valve core 3 closes the outlet of the water inlet 2 under the action of the valve core return spring 6, playing a role in preventing reverse flow. When the flow rate needs to be adjusted, the guide disc drive shaft 13 is rotated by adjusting the handle 11, thereby driving the rotating water guide disc 8 to rotate, causing the flow adjustment hole 9 and the through holes of the fixed water guide disc 5 to be misaligned, thereby changing the size of the through holes of the fixed water guide disc 5, and thus adjusting the flow rate, realizing a water flow check valve capable of adjusting the flow rate.

[0026] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present invention, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
