[0002] A solenoid valve is a device that uses electromagnetic force to control the flow of fluid. Its working principle is based on the magnetic field generated by the electromagnetic coil to manipulate the valve or valve core to control the flow of fluid. In the self-holding high-efficiency and energy-saving solenoid valve, a stable and reliable solenoid valve technology is required to ensure that the original state can be maintained after power failure. The self-holding high-efficiency and energy-saving solenoid valve can be used in various occasions that require fluid control, such as industrial automation, hydraulic systems, air conditioning systems, water supply systems, etc. There is a closed cavity in the solenoid valve, and through holes are opened at different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side the magnet coil is energized. By controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the piston of the oil cylinder is pushed by the oil pressure, and the piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.

The self-holding high-efficiency energy-saving solenoid valve is provided with a mounting mechanism, and the mounting mechanism pushes the push rod, and the push rod drives the moving block and the limit rod to move, inserts the fixed block into the box body, and then releases the push rod, and the spring drives the moving block and the limit rod to reset, so that the limit rod is inserted into the limit groove, so that the solenoid valve body is fixedly installed. Compared with the traditional self-holding high-efficiency energy-saving solenoid valve, the installation and disassembly are relatively simple, making the installation convenient, but this kind of self-holding high-efficiency energy-saving solenoid valve is difficult to make the solenoid valve achieve energy saving, and needs to be improved.

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-2As shown, this embodiment proposes a self-holding high-efficiency energy-saving solenoid valve, including an inlet 1, an outer surface of the inlet 1 is fixedly connected to one end of a solenoid valve body 2, an end of the solenoid valve body 2 away from the inlet 1 is fixedly connected to an outlet 3, an energy-saving device 4 is arranged inside the solenoid valve body 2, and the energy-saving device 4 includes a stepper motor 41, the stepper motor 41 is fixedly connected to the outer surface of the solenoid valve body 2, the output shaft of the stepper motor 41 is fixedly connected to a rotating rod 43, the outer surface of the stepper motor 41 is fixedly connected to one end of a connecting rod 42, and the connecting rod 42 is away from the stepper motor. An adjusting switch 45 is provided at one end of the machine 41, a valve plate 44 is fixedly connected to the outer surface of the rotating rod 43, a connecting plate 46 is fixedly connected to the outer surface of the solenoid valve body 2, an arc-shaped bar 47 is fixedly connected to the outer surface of the connecting plate 46, a strip plate 48 is fixedly connected to the outer surface of the arc-shaped bar 47, a cylinder 49 is fixedly connected to the outer surface of the strip plate 48, a touch rod 410 is fixedly connected to the outer surface of the strip plate 48, the adjusting switch 45 is located on the movement trajectory of the touch rod 410, the valve plate 44 is located on the movement trajectory of the rotating rod 43, and the valve plate 44 is a semi-arc shape.

[0025] In this embodiment, first, the power cord of the solenoid valve is connected to an appropriate power supply, and then the inlet and outlet of the solenoid valve are connected to the pipeline to be controlled. At this time, the fluid enters the solenoid valve body 3 from the inlet 1. When entering, the stepper motor 41 on the solenoid valve body 3 is in a closed state. After no fluid enters, the user turns on the adjustment switch 45. After turning on the adjustment switch 45, the stepper motor 41 will turn on. The stepper motor 41 turns on and drives the rotating rod 43 to rotate. The rotation of the rotating rod 41 will drive the valve plate 44 to rotate. The valve plate 44 will close the inside of the solenoid valve body 2. When the fluid is about to enter the solenoid valve body 2, the valve plate 44 will open. When it rains, rainwater will drip into the cylinder 49. The cylinder 49 will be very heavy after being filled with water. The weight of the cylinder 49 will cause the strip plate 48 to move downward, and the other half of the cylinder 49 will rise. The strip plate 48 will drive the touch rod 410 to rise, and the touch rod 410 will touch the adjustment switch 45. The adjustment switch 45 will open the valve plate 44 in stages, so that the valve plate 44 will open according to the size of the fluid, thereby realizing that the solenoid valve can save energy by setting the adjustment switch.

[0026] Example 2
