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
The invention belongs to the vacuum valve technical field, be specifically related to a kind of Miniature vacuum valve for flywheel.
Background technique
In posture adjustment and accumulated energy flywheel research, flywheel need be operated in high vacuum environment.At present, flywheel product cavity vacuumizes and seals both at home and abroad, generally adopts flanged joint to weld the structural type of one section oxygen-free copper pipe and rubber seal again.Oxygen-free copper pipe one end and vacuum-pump line are welded to connect, vacuumize by oxygen-free copper pipe, after flywheel vacuum cavity degree of vacuum is up to standard, adopt special caliper that oxygen-free copper pipe end flattening is stuck, block afterwards and sealing immediately, the copper pipe that blocks is left on the flywheel cavity as Sealing, thereby reaches the seal request of degree of vacuum after up to standard.When vacuumizing for the second time, former flanged joint formula sealing configuration is removed, discards, the work such as the welding that need repeat to vacuumize for the first time, card envelope.
The said structure form has the forms such as welded seal, rubber seal, card envelope, and sealing part is more, and operating process is complicated, when repeating to vacuumize, sealing configuration originally is removed discarded, the waste material, the oxygen-free copper pipe that is truncated is simultaneously stayed on the flywheel vacuum cavity, takes up room, and affects attractive in appearance.
Simultaneously along with the microminaturization of flywheel product, flywheel vacuum cavity volume diminishes thereupon, and the required installing space of traditional vacuum valve is large with respect to the ratio that flywheel vacuum cavity volume takies, and can not satisfy the flywheel vacuum cavity to the miniaturization requirement of vacuum valve.
Summary of the invention
Operating process complexity, the waste material, the technical problem large, that impact is attractive in appearance that takes up room that exist in order to solve prior art the invention provides a kind of Miniature vacuum valve for flywheel, satisfy the flywheel vacuum cavity to the requirement of vacuum valve miniaturization.
The technological scheme that technical solution problem of the present invention is taked is as follows:
A kind of Miniature vacuum valve for flywheel comprises the interface of bleeding, an O RunddichtringO, valve body, spool and the 2nd O RunddichtringO; Spool is for being provided with internal thread and externally threaded pair of worm structure, and the inside of spool is cavity structure, and the chamber wall of spool is provided with bleeding point; Insert in the cavity of spool the bleed bottom of interface, and be connected with the screw-internal thread fit of spool; Between the cavity bottom of the bottom end face of interface and spool of bleeding, the space is arranged, the bleeder hole at the interface center of bleeding communicates with the cavity of spool; The outside thread of valve body and spool is connected; Bleeding is tightly connected by an O RunddichtringO between interface and valve body, is tightly connected by the 2nd O RunddichtringO between valve body and spool.
The above-mentioned interface of bleeding is piston cylinder operator; The outside thread of described spool and the rotation direction of internal thread, pitch and helical pitch are identical.
Beneficial effect of the present invention is as follows:
1, this Miniature vacuum valve has the advantages that volume is little, simple in structure, easy to use, quality is light, has reduced the weight of flywheel product.
2, for microminiature flywheel product, this Miniature vacuum valve is not subjected to the restriction of installing space, position, and simultaneously valve body itself is exactly the part of flywheel vacuum cavity, and level of integration is high, and after exhausting vacuum and closing, the interface of bleeding can unload, and does not affect product attractive in appearance.
3, save the welded seal of existing package system, improved flywheel product sealing effect and reliability, reduced the waste of material.
Description of drawings
Fig. 1 is the structural representation of Miniature vacuum valve for flywheel of the present invention.
Fig. 2 is the structural representation after Miniature vacuum valve for flywheel of the present invention is arranged on vacuum cavity.
Fig. 3 is that Miniature vacuum valve for flywheel of the present invention exhausts the structural representation after the interface of bleeding after vacuum withdraws from.
In figure: 1, the interface of bleeding, the 2, the one O RunddichtringO, 3, valve body, 4, spool, the 5, the 2nd O RunddichtringO, 6, bleeding point.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1 to Figure 3, Miniature vacuum valve for flywheel of the present invention mainly is comprised of the interface 1 of bleeding, an O RunddichtringO 2, valve body 3, spool 4, the 2nd O RunddichtringO 5.Wherein, valve body 3 is the part of flywheel vacuum cavity, the rotation vacuum cavity rotates valve body 3, the coordinating of spool 4 and valve body 3, spool 4 are with the coordinating of interface 1 of bleeding and are threaded, spool 4 is two worm structures, and outside thread and internal thread rotation are identical to, pitch and helical pitch, and employing the 2nd O RunddichtringO 5 seals, the interface 1 of bleeding is piston cylinder operator, adopts an O RunddichtringO 2 to seal.
Forward rotation valve body 3 keeps bleeding not produce between interface 1 and valve body 3 relatively moving simultaneously, and this moment, spool 4 drive the 2nd O RunddichtringOs 5 outwards withdrawed from together, thereby open valve, begin to bleed by the bleeder hole on the interface 1 of bleeding and the bleeding point 6 on spool 4, bleed complete after, reverse rotation valve body 3, spool 4 is return, and valve closing is when being rotated further valve body 3, the interface 1 of bleeding outwards withdraws from, so far complete the operation that vacuumizes of flywheel cavity, at this moment, can unload lower pumping interface 1.
