[0002] One-way valve is a commonly used control component in all walks of life. It has many varieties and wide applications. One-way valve is one of the main components. It mainly uses the valve to block the valve port to cut off the channel fluid, control the system pressure and prevent the channel fluid from flowing in reverse, effectively ensuring the function of controlling flow.

[0003] When the existing one-way water valve is closed, when the water flow pressure on the ball core is too large, there is a possibility that the ball core will be impacted into the water inlet hole of the product, causing a jam. When the existing one-way water valve is in a normally open state, when the water flow pressure on the ball core is too large, there is a possibility that the ball core will be impacted into the drainage hole of the product, causing a jam, which greatly reduces the service life of the product.

[0019] like Figure 1-4 As shown, a one-way water valve for preventing sticking includes a water outlet valve body 1 and a water inlet valve body 2, wherein the water outlet valve body 1 and the water inlet valve body 2 are connected to form a one-way valve, a ball core 3 is arranged in the valve port of the water outlet valve body 1, four mounting grooves 5 are opened on the inner wall of the valve port of the water outlet valve body 1, and the mounting grooves 5 are opened on the inclined wall of the inlet inside the water outlet valve body 1, and the angle between two adjacent mounting grooves 5 is 90°.

[0020] A water inlet limit assembly is connected in the installation groove 5, and the water inlet limit assembly includes a pressure plate 7 and a T-shaped rod 8. The pressure plate 7 is placed in a placement groove 9 opened on the inclined wall of the inlet of the water outlet valve body 1. A slot 10 is opened on the bottom surface of the placement groove 9, and a slide groove 11 is opened at the bottom of the slot 10. One end of the T-shaped rod 8 is connected to the pressure plate 7, and the other end of the T-shaped rod 8 is slidably connected in the slide groove 11. A spring 12 is sleeved on the rod body of the T-shaped rod 8 placed in the slot 10, one end of the spring 12 is connected to the bottom of the slot 10, and the other end is connected to the pressure plate 7. A baffle 13 is connected to the bottom of the pressure plate 7. When the one-way valve is opened, the ball core 3 is pressed on the pressure plate 7, so that the pressure plate 7 is pressed into the placement groove 9, the spring 12 is compressed, and a reverse force is applied to the ball core 3 to prevent the pin from getting stuck, and the baffle 13 is used as the position of the ball core 3 to further prevent sticking.
