[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] See also Figure 1-Figure 5 A plastic-sealed valve body structure includes a plastic-sealed shell 10 and a valve core module 20, wherein the valve core module 20 is plastic-sealed inside the plastic-sealed shell 10; the valve core module 20 includes a valve core frame 210, wherein a valve core channel 211 with a lower end opening is provided in the valve core frame 210, wherein a valve core 30 that moves up and down relative to the valve core channel 211 is provided in the valve core channel 211, and the valve core frame 210 is provided with an electromagnetic module 230; the electromagnetic module 230 is used to drive the valve core 30 to move upward. In this embodiment, the setting of a plastic-sealed shell is added, and a shell is wrapped around the outside of the valve core module by a plastic-sealed process, which can effectively ensure the sealing performance, thereby preventing external liquid from entering the valve core module. The overall waterproof performance is improved to extend the service life of the product and ensure the stability of the product.

[0030] See also Figure 3 and Figure 4 The upper end of the valve core channel 211 is open, a seal 260 is fixedly arranged inside the upper end of the valve core channel 211, and a sealing ring 270 is arranged on the peripheral wall of the seal 260 to fit the valve core channel 211. The upper end of the valve core channel 211 is open for better production of the valve core frame 210, and the seal 260 is used to close the upper end of the valve core channel 211.

[0031] See also Figures 3 to 5 The valve core channel 211 is provided with an elastic component 50 for driving the valve core 30 to move downward. The elastic component 50 exerts a force on the valve core 30, so that the valve core 30 moves downward to a closed position under the force, so that the valve body is in a closed state.

[0032] See also Figure 5 The valve core 30 is provided with a connecting passage 320 with an upper end opening, and the elastic component 50 is arranged in the connecting passage 320 .

[0033] Further, the elastic component 50 includes a limit ring 510 fixedly arranged in the connecting channel 320, a moving part 520 is movably inserted in the limit ring 510, and the moving part 520 is fixedly connected with a limit clamping ring 530 that fits with the lower surface of the limit ring 510; the upper end of the moving part 520 is against the inner wall of the upper end of the valve core channel 211; the lower end of the moving part 520 is connected to a reset spring 540, and the lower end of the reset spring 540 fits with the inner wall of the lower end of the connecting channel 320. In this embodiment, the function of the limit ring 510 is to prevent the moving part 520 from detaching from the valve core channel 211 from bottom to top. The function of the moving part 520 is to prevent the reset spring 540 from detaching from the valve core channel 211. Since the valve body can be used in agricultural irrigation, there will be particles in the liquid flowing through the valve body. When the user cleans the valve core in the future, the valve core 30 can be pulled out downward for cleaning. At this time, the limiting ring 510 can prevent the spring from separating from the valve core to ensure the integrity of the product.

[0034] See also Figure 5 A positioning column 550 extending downward is provided at the lower end of the moving member 520 , and the positioning column 550 is plug-fitted with the return spring 540 .

[0035] See also Figure 3 A water flow gap is provided between the valve core 30 and the valve core channel 211, and the valve core 30 is provided with a transverse flow channel 310 that transversely penetrates the valve core 30, and both ends of the transverse flow channel 310 are connected to the water flow gap. Due to the effect of the water flow gap, when the valve core 30 moves downward to close the valve body, the water flow squeezed out by the downward movement of the valve core 30 can flow into the water flow gap to reduce the resistance of the valve core 30 moving downward.

[0036] See also Figure 1 and Figure 2 The plastic shell 10 is connected to a plug 110 , and the plastic shell 10 and the plug 110 are an integrally formed structure.

[0037] See also Figure 3 A connecting portion 212 is provided at the lower end of the valve core frame 210, and the connecting portion 212 is detachably connected to a water stop member 40, and a water stop cavity 213 is formed between the connecting portion 212 and the water stop member 40; the water stop member 40 is provided with an inlet channel 410 and a water outlet channel 420 which are interconnected with the water stop cavity 213, and the valve core channel 211 is interconnected with the water stop cavity 213; when the valve core 30 moves downward, it can abut against the bottom wall of the water stop cavity 213 to block the water outlet channel 420.

[0038] The valve body is a normally closed valve. In the closed state, the valve core 30 abuts against the bottom wall of the water stop cavity 213 to block the water outlet channel 420. Water flows from the water inlet channel 410 to the water stop cavity 213 and cannot flow out from the water outlet channel 420.

[0039] When the valve body is in the open state, the electromagnetic module 230 is energized to generate a magnetic field to drive the valve core 30 to move upward, so that the valve core 30 is separated from the bottom wall of the water stop cavity 213, and the water outlet channel 420 is opened. The liquid in the water stop cavity 213 can be discharged from the water outlet channel 420.

[0040] See also Figure 4 The plastic package shell 10 is a shell with a hollow interior and an opening 100 at the lower end. The opening 100 is in contact with the outer wall of the lower end of the valve core frame 210 .

[0041] See also Figure 3 and Figure 4 The valve core module 20 also includes an outer bracket 220, an installation space 240 is set between the outer bracket 220 and the valve core frame 210, and the electromagnetic module 230 is set in the installation space 240; a connecting piece 250 is set at the lower end of the valve core frame 210 and fixedly connected to the outer bracket 220.
