DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.
[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments. Embodiment
[0022] See Figures 1 - 4 , this embodiment provides a solenoid valve with optimized performance, including a valve body 1. A valve seat 2 is fixedly connected above the valve body 1. A valve core assembly 3 is arranged on the inner surface of the valve seat 2. The valve core assembly 3 includes a valve sleeve 301. A valve rod 302 is slidably connected to the inner surface of the valve sleeve 301. A piston 303 is fixedly connected to the lower end of the valve rod 302. The valve core assembly 3 further includes a moving iron core 304. The moving iron core 304 is fixedly connected to the outer surface of the valve sleeve 301. The moving iron core 304 is slidably connected to the inner surface of the valve seat 2. A fixed iron core 305 is arranged above the moving iron core 304. The fixed iron core 305 is movably sleeved on the outer surface of the valve sleeve 301. The fixed iron core 305 is annular in shape. An adjusting assembly 4 is arranged above the valve sleeve 301. The adjusting assembly 4 includes an electric push rod 401. The electric push rod 401 is fixedly connected to the upper end of the valve rod 302. A propulsion assembly 5 is arranged above the electric push rod 401. A sealing piece 6 is slidably connected to the outer surface of the valve sleeve 301. The sealing piece 6 is fixedly connected to the inner surface of the valve seat 2. The sealing piece 6 is annular in shape. A closing plate 9 is fixedly connected to the inner surface of the valve body 1. A through hole 10 is opened above the closing plate 9. The through hole 10 is adapted to the piston 303. The piston 303 is used to close the through hole 10 on the closing plate 9. Coils 8 are fixedly installed on both the left and right sides of the valve seat 2. The coils 8 are adapted to the moving iron core 304. The coils 8 are used to control the up and down movement of the moving iron core 304, thereby driving the valve sleeve 301 and the valve rod 302 to open or close the through hole 10 on the closing plate 9 by the piston 303.
[0023] When the above-mentioned device is in specific use, the water flow passes through the valve body 1. The water flow will pass through the through hole 10 on the closing plate 9. The piston 303 will block the through hole 10 on the closing plate 9. The coil 8 is used to control the upward movement of the moving iron core 304 to drive the valve sleeve 301 and the valve rod 302 to make the piston 303 rise. At this time, the piston 303 will move away from the through hole 10 on the closing plate 9, so that the valve body 1 is opened. The electric push rod 401 is used to pull the valve rod 302 to slide upward in the valve sleeve 301, so that the distance between the piston 303 and the valve sleeve 301 is shortened. At this time, the piston 303 will move away from the through hole 10 on the closing plate 9, so that the valve body 1 is switched to the normally open state. The coil 8 is used to control the downward movement of the moving iron core 304 to drive the valve sleeve 301 and the valve rod 302 to make the piston 303 descend. At this time, the piston 303 will block the through hole 10 on the closing plate 9, so that the valve body 1 is closed. Embodiment
[0024] See Figures 1 - 4 , on the basis of Embodiment 1, the adjusting assembly 4 further includes a support seat 402. The support seat 402 is fixedly connected above the valve sleeve 301. The shape of the support seat 402 is L-shaped. The propulsion assembly 5 includes a slider 501. The slider 501 is fixedly connected to the upper end of the electric push rod 401. The slider 501 is slidably connected to the inner surface of the support seat 402. A screw rod 502 is rotatably connected above the slider 501. The screw rod 502 is threadedly penetrated through the upper part of the support seat 402. A sealing cover 7 is threadedly connected above the valve seat 2. Threads are provided on the inner edge of the sealing cover 7 and the upper edge of the valve seat 2. The top of the inner surface of the sealing cover 7 is fixedly connected to the upper part of the fixed iron core 305. The sealing cover 7 is movably sleeved on the outer surface of the valve sleeve 301.
[0025] When the above-mentioned device is in specific use, when the piston 303 cannot tightly seal the through hole 10 on the closing plate 9, the screw rod 502 is rotated to drive the slider 501 to descend. The downward movement of the slider 501 will drive the electric push rod 401, the valve rod 302 and the piston 303 to descend as a whole, so that the piston 303 re-presses the through hole 10 on the closing plate 9 to enhance the sealing effect. The sealing cover 7 is rotated to be disassembled from above the valve seat 2, and the sealing cover 7 will drive the fixed iron core 305 to be disassembled together. At this time, the structure inside the valve seat 2 can be repaired, achieving the effect of facilitating maintenance.
[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
