Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as Figure 1 to Figure 3 As shown, the miniature vacuum valve for flywheel of the present invention is mainly composed of an air extraction interface 1, a first O-ring 2, a valve body 3, a valve core 4, and a second O-ring 5. Among them, the valve body 3 is a part of the flywheel vacuum chamber, and the rotation of the vacuum chamber makes the valve body 3 rotate, the cooperation between the valve core 4 and the valve body 3, and the cooperation between the valve core 4 and the air extraction interface 1 are all threaded connections, and the valve core 4 is a double-thread structure, the outer thread and the inner thread have the same direction of rotation, pitch and lead, and the second O-ring 5 is used for sealing. The air extraction interface 1 is a piston structure, and the first O-ring 2 is used for seal.

Abstract

The invention discloses a miniature vacuum valve for a flywheel, and relates to the technical field of vacuum valves. The vacuum valve comprises an air exhausting joint (1), a first O-shaped sealing ring (2), a valve body (3), a valve core (4) and a second O-shaped sealing ring (5); the valve body (3) is a part of a vacuum cavity of the flywheel; the vacuum cavity is rotated to rotate the valve body (3); the valve core (4) is in a double-thread structure; the rotation directions, the thread pitches and the leads of an external thread and an internal thread are completely identical; the valve core (4) is matched with the valve body (3) in a threaded connection way; the valve core (4) is matched with the air exhausting joint (1) in a threaded connection way; and the air exhausting joint (1)is in a piston type structure and is sealed by adopting the first O-shaped sealing ring (2). The vacuum valve has the characteristics of small size, simple structure, convenience in use and light weight; the weight of a flywheel product is reduced; the requirement of the microminiature flywheel product on the miniaturization of the vacuum valve is met; after the miniature vacuum valve is vacuumized completely and closed, the air exhausting joint can be disassembled; and the attractiveness is not influenced.

Description

technical field [0001] The invention belongs to the technical field of vacuum valves, in particular to a miniature vacuum valve for flywheels. Background technique [0002] In the attitude adjustment and energy storage flywheel research, the flywheel needs to work in a high vacuum environment. At present, domestic and foreign flywheel products generally use a flange joint to weld a section of oxygen-free copper tube and seal it with glue to vacuumize and seal the cavity. One end of the oxygen-free copper tube is welded and connected to the vacuum pump pipe, and the vacuum is pumped through the oxygen-free copper tube. When the vacuum degree of the flywheel vacuum chamber reaches the standard, the end of the oxygen-free copper tube is crushed and stuck with a special caliper, and then cut off and welded immediately. , the truncated copper tube is left on the flywheel cavity as a seal, so as to meet the sealing requirements after the vacuum degree reaches the standard. When ...
