Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a rigidity valve with magnetic steel. Background Art

[0002] The stiffness valve adjusts the hardness of the suspension in real time based on factors such as vehicle speed, road conditions and load to provide optimal suspension performance and driving comfort. It is a vital component in the air suspension system and plays a vital role in improving the vehicle's suspension performance and driving comfort.

[0003] Existing stiffness valves, such as patent application number CN202322326956.8, disclose an elastic guide ring, a moving iron core guide structure and a solenoid valve, and patent application number CN202410944577.1 discloses a valve core assembly for an air spring stiffness valve and an air spring stiffness valve. The above two existing stiffness valves are made of soft magnetic material inside. After power is applied, the coil magnetizes the soft magnetic material to generate electromagnetic force, and the electromagnetic force is used to switch the closing and opening functions of the stiffness valve. However, the magnetic force of this type of structure is limited after power is applied, and a faster response effect cannot be achieved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a stiffness valve with magnetic steel, which has a simple structure, a shorter response time, is more sensitive, reduces power consumption, and is more energy-saving and environmentally friendly.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A stiffness valve with magnets comprises a steel sleeve, a static core, a coil, a dynamic core, a valve stem, a plug assembly, a guide sleeve, a valve core assembly and a valve seat. The coil is fixed in the steel sleeve, the plug assembly is installed at the left end of the steel sleeve, the static core is installed at the right end of the steel sleeve, the coil is equipped with a guide sleeve, the guide sleeve is fixed at the left end of the static core, the dynamic core is located in the guide sleeve, the valve stem is installed on the dynamic core, the valve core assembly is installed at the right end of the valve stem, a spring is sleeved on the outer circumference of the valve stem and located between the static core and the dynamic core, a valve seat is also installed at the right end of the steel sleeve, a magnetic steel frame is sleeved on the outer circumference of the guide sleeve and located between the plug assembly and the coil, and a magnet is fixed on the magnetic steel frame.

[0007] A further technical solution is that at least two pieces of magnets are fixed on the magnetic frame along the inner circle. In this embodiment, two pieces of magnets are fixed at the front and back, respectively, so that the magnetic field generated in the surrounding areas is more evenly distributed.

[0008] A further technical solution is that magnetic steel installation grooves are distributed on the inner circumference of the magnetic steel frame, and the magnetic steel is fixed in the magnetic steel installation grooves and needs to cooperate with the outer circumference of the guide sleeve inside the magnetic steel frame.

[0009] A further technical solution is that the magnetic steel installation groove and the magnetic steel are both fan-shaped structures.

[0010] The beneficial effects of the utility model are:

[0011] The utility model discloses a stiffness valve with a magnet. A magnet is added to the middle part of a magnetic steel frame. After the stiffness valve is energized, the magnetic field of the coil can quickly magnetize other parts under the action of the magnetic field of the magnet itself, thereby improving the starting response time of the stiffness valve. During the process of the stiffness valve being continuously energized and opened, the magnetic force of the magnet and the electromagnetic force of the coil are combined to well maintain the closed state of the stiffness valve. A smaller current can be loaded on the coil to continuously maintain the closed state of the stiffness valve, which is more energy-saving and environmentally friendly and reduces power consumption.

[0018] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0019] See Figures 2 to 4As shown, a stiffness valve with a magnet comprises a steel sleeve 4, a static core 6, a coil 5, a dynamic core 9, a valve stem 10, a plug assembly 1, a guide sleeve 12, a valve core assembly 8 and a valve seat 7. The coil 5 is fixed in the steel sleeve 4, the plug assembly 1 is installed at the left end of the steel sleeve 4, the static core 6 is installed at the right end of the steel sleeve 4, the coil 5 is built with a guide sleeve 12, the guide sleeve 12 is fixed to the left end of the static core 6, the dynamic core 9 is located in the guide sleeve 12, the valve stem 10 is installed on the dynamic core 9, the valve core assembly 8 is installed at the right end of the valve stem 10, a spring 11 is further sleeved on the outer circumference of the valve stem 10 and located between the static core 6 and the dynamic core 9, the valve seat 7 is further installed at the right end of the steel sleeve 4, a magnetic steel frame 2 is further sleeved on the outer circumference of the guide sleeve 12 and located between the plug assembly 1 and the coil 5, and a magnet 3 is fixed on the magnetic steel frame 2.

[0020] At least two magnets 3 are fixed along the inner circle of the magnetic frame 2. In this embodiment, two magnets 3 are fixed at the front and two at the back, creating a more uniform magnetic field distribution. Magnetic mounting slots 13 are distributed along the inner circumference of the magnetic frame 2. The magnets 3 are fixed within these slots and mate with the outer circumference of the guide sleeve 12 inside the magnetic frame 2. Both the magnetic mounting slots 13 and the magnets 3 have a fan-shaped structure.

[0021] In this embodiment, the coil 5 of the stiffness valve generates a magnetic field after being energized. As the current of the coil 5 increases, the steel sleeve 4, magnetic steel frame 2, dynamic core 9 and static core 6 in the stiffness valve are magnetized. Figure 4 A loop is formed in the direction indicated by the arrow. When the electromagnetic force of the magnetic field reaches a certain intensity and overcomes the elastic force of the spring 11, the static core 6 attracts the dynamic core 9. The dynamic core 9 is as shown in FIG. Figure 4 As shown, the valve stem 10 and valve assembly 8 move to the right along the direction indicated by the arrow, and the valve stem 10 and valve assembly 8 move together with the dynamic core 9. The valve assembly 8 fits against the valve seat 7, thereby realizing the process of the stiffness valve from normally open to closed. During the closing process of the stiffness valve, the coil 5 needs to be continuously energized. When the coil 5 is not energized, the electromagnetic force of its magnetic field is less than the elastic force of the spring 11. Under the action of the spring 11, the dynamic core 9 rebounds to its original position, and the stiffness valve switches back to the normally open state.

[0022] Existing Figure 1 The magnetic steel frame shown is made of soft magnetic material and has no magnetism itself. The utility model adds a magnet 3 (high-temperature resistant permanent magnet) to the magnetic steel frame 2. After the stiffness valve is energized, the magnetic field of the coil 5 can be affected by the magnetic field of the magnet 3 itself. The magnetic field generated by the coil 5 can quickly magnetize other parts, thereby improving the startup response time of the stiffness valve. When the stiffness valve is continuously energized and opened, the magnetic force of the magnet 3 and the electromagnetic force of the coil 5 are combined to well maintain the closed state of the stiffness valve.

[0023] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that are not conceived through creative work should be included in the protection scope of the present invention.
