Technical Field

[0001] The utility model relates to the technical field of valves, and specifically, to a rotor solenoid valve. Background Art

This design not only limits the application range of the solenoid valve, but also affects the precise control of the flow rate to a certain extent. Therefore, there is an urgent need in the market for a new type of solenoid valve that can overcome the above defects, realize the shut-off and opening of the valve through electromagnetic rotation, and can precisely control the size of the valve passage through the rotation angle, thereby realizing the precise control of the flow rate.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a rotor solenoid valve, as Figures 1 - 4 shown, which includes a valve seat 1 and several valve bodies 2. The valve seat 1 and the valve bodies 2 are installed together by screws. Multiple valve bodies 2 can be assembled on one valve seat 1 to achieve multiple channels. Inside the valve body 2, there are a rotor 10 and a coil 11. A valve core shaft 6 is installed inside the rotor 10. At the bottom end of the valve core shaft 6, there is a sealing shaft 3 connected by threads. The coil 11 is composed of a bobbin 14 and a coil winding 15. Inside the bobbin 14, there are multiple wire grooves. Through ingenious design, the flexible combination of the valve seat 1 and the valve bodies 2 is realized, so that multiple valve bodies 2 can be conveniently assembled on one valve seat 1, thus forming a multi-channel structure. This design not only improves the functionality of the solenoid valve, but also enhances its adaptability and flexibility in practical applications. At the same time, the rotor 10 and the coil 11 arranged inside the valve body 2, as well as the valve core shaft 6 installed inside the rotor 10 and the sealing shaft 3 connected by threads, together constitute a precise electromagnetic driving mechanism. This mechanism enables the solenoid valve to realize the rotation of the valve core and the up and down movement of the sealing shaft through electromagnetic force, so as to accurately control the opening and closing and the flow rate of the valve. In addition, the coil 11 adopts the structure of the bobbin 14 and the coil winding 15. Inside the bobbin 14, there are multiple wire grooves. This design not only improves the heat dissipation performance of the coil, but also is conducive to the stable and uniform distribution of electromagnetic force, further improving the working performance and reliability of the solenoid valve.

[0024] In this embodiment, under the action of the electrode switching of the coil 11, the rotor 10 rotates, thereby driving the valve core shaft 6 to rotate. The threads of the valve core shaft 6 drive the sealing shaft 3 to move up and down.

[0025] Specifically, a bobbin 14 is installed in the middle of the coil 11 to ensure the overall fixation of the coil 11.

[0026] Furthermore, a fixing seat 7 is installed at the top of the valve seat 1 near the valve body 2. The fixing seat 7 is connected to the valve seat through a fixing seat sealing ring 8, and blocks the intake passage between the valve seat and the valve body.

[0027] Furthermore, the sealing shaft 3 is connected to the sealing seat 4 through a sealing shaft sealing ring 9, and blocks the intake passage between the valve seat and the valve body.

[0028] Further, a sealing seat 4 is installed inside the valve seat 1 at the bottom end of the sealing shaft 3, and a sealing seat sealing ring 5 is arranged between the outer wall of the sealing seat 4 and the inner wall of the valve seat 1 to ensure the sealing performance of the sealing seat 4.

[0029] Further, a sealing shaft sealing ring 9 is installed on the outer side of the sealing shaft 3 near the bottom of the fixed seat 7 to ensure the sealing performance of the sealing shaft 3.

[0030] Further, a safety valve 12 is installed on one side of the bottom of the valve seat 1, and a plug 13 is installed on the other side of the bottom of the valve seat 1.

[0031] When the rotor solenoid valve of the present utility model is in use, first, when the coil 11 is energized, its electrodes switch to generate an electromagnetic force, driving the rotor 10 to rotate inside the coil 11. The rotational movement of the rotor 10 further drives the valve core shaft 6 to rotate. Since the bottom end of the valve core shaft 6 is threadedly connected to the sealing shaft 3, the rotational movement of the valve core shaft 6 will be converted into the up and down movement of the sealing shaft 3.

[0032] When the valve needs to be opened, the coil 11 is energized to generate an electromagnetic force, driving the rotor 10 to rotate, and then driving the valve core shaft 6 and the sealing shaft 3 to move upward, so that the seal between the sealing shaft 3 and the sealing seat 4 is broken, and the intake passage is communicated with the valve body, allowing the gas to pass through. On the contrary, when the valve needs to be closed, the coil 11 is de-energized, the electromagnetic force disappears, and the rotor 10, the valve core shaft 6 and the sealing shaft 3 move downward under the action of gravity or spring force, and the sealing shaft 3 fits tightly with the sealing seat 4 again, blocking the intake passage and the valve body, thereby realizing the closing of the valve.

[0033] In addition, a fixed seat 7 is installed on the top of the valve seat 1 near the valve body 2. The fixed seat 7 is connected to the valve seat through a fixed seat sealing ring 8, which not only ensures the stable installation of the valve body, but also effectively blocks the intake passage and the valve body, improving the sealing performance of the solenoid valve. The sealing shaft 3 is connected to the sealing seat 4 through a sealing shaft sealing ring 9, which also ensures the sealing between the intake passage and the valve body. The sealing seat sealing ring 5 arranged between the outer wall of the sealing seat 4 and the inner wall of the valve seat 1, and the sealing shaft sealing ring 9 installed on the outer side of the sealing shaft 3 near the bottom of the fixed seat 7 further enhance the sealing effect of the solenoid valve.

[0034] During the working process of the solenoid valve, the safety valve 12 installed on one side of the bottom of the valve seat 1 plays an important protective role. When the internal pressure of the solenoid valve is too high, the safety valve 12 will automatically open to release some gas to reduce the internal pressure of the solenoid valve and prevent the solenoid valve from being damaged due to excessive pressure. The plug 13 installed on the other side of the bottom of the valve seat 1 is used to seal the bottom opening of the solenoid valve to ensure the overall sealing performance of the solenoid valve.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, which are not used to limit the present utility model.
