Abstract
The present invention relates to a kind of heat pipe outlet valve, comprise spool, valve seat, metal hollow seal ring, the endoporus of valve seat is that internal thread coordinates with the outside thread of spool, spool and valve seat are all designed with circular groove, metal hollow seal ring is placed in circular groove, rotary spool makes it move downward and compresses metal hollow seal ring, the thread center of spool has longitudinal aperture, radial direction is provided with horizontal apertures, longitudinal aperture communicates with horizontal apertures, the inner ring of metal hollow seal ring is circumferentially provided with balance aperture, radial hole communicates with balance aperture, rotary spool makes it move upward, and unclamps metal hollow seal ring, now heat pipe gas can be discharged by the longitudinal aperture of spool and radial hole.The design is owing to have employed elastic metallic hollow sealing ring, and the inner ring of metal hollow seal ring is circumferentially designed with balance aperture, make the larger sealability of heat pipe internal pressure better, unclamping rear cross section can resilience, this outlet valve can be vented repeatedly, reliable sealing repeatedly.
Description
Technical field
The present invention relates to a kind of heat pipe outlet valve, be applicable to heat pipe and produce or in using process, get rid of air or the incoagulable gas of heat pipe by hot type method.
Background technique
The air in hot type method discharge heat pipe or incoagulable gas is used to be that heat pipe is produced or a kind of means conventional in using process, for ensureing the degree of vacuum in heat pipe after being vented, effective sealing need be carried out to after exhaust, conventional is weld after directly pressing from both sides flat outlet pipe, this method is in heat pipe Long-Time Service in the future, and cannot regenerate by opposite heat tube, the time one is of a specified duration, incoagulable gas is cumulative, and heat pipe will lose efficacy.A small amount of heat pipe also can use outlet valve, and the sealing effect of outlet valve and sealing number of times 2 are all difficult to satisfactory.
Summary of the invention
The invention provides for above problem a kind ofly can be repeatedly vented, the new heat pipe outlet valve of reliable sealing repeatedly.
A kind of heat pipe outlet valve is the invention provides in order to overcome the above problems, comprise spool, valve seat, it is characterized in that: also comprise metal hollow seal ring, the endoporus of valve seat is that internal thread coordinates with the outside thread of spool, spool and valve seat are all designed with circular groove, metal hollow seal ring is placed in circular groove, rotary spool makes it move downward and compresses metal hollow seal ring, the thread center of spool has longitudinal aperture, radial direction is provided with horizontal apertures, longitudinal aperture communicates with horizontal apertures, the inner ring of metal hollow seal ring is circumferentially provided with balance aperture, radial hole communicates with balance aperture, rotary spool makes it move upward, and unclamps metal hollow seal ring, now heat pipe gas can be discharged by the longitudinal aperture of spool and radial hole.Described metal hollow seal ring has elasticity.The design is owing to have employed elastic metallic hollow sealing ring, and the inner ring of metal hollow seal ring is circumferentially designed with balance aperture, makes the larger sealability of heat pipe internal pressure better; Again because metal hollow seal ring has certain elasticity, unclamping rear cross section can resilience, this outlet valve can be vented repeatedly, reliable sealing repeatedly.
As a modification of the present invention, described spool and the circular groove of seat design are trapezoid cross section circular groove.Due to the setting of trapezoid cross section circular groove, have up and down totally 6 sealing surfaces after making metal hollow seal ring compacted, greatly improve the reliability of sealing.
Improve as another kind of the present invention, vibration is produced because heat pipe operationally can be subject to fluid impact, therefore locking cap is also set in the periphery of spool, locking cap and valve seat have screw-thread fit, after exhaust completes, screwing locking cap can pressed spool, locking cap be arranged so that heat pipe vibrates time spool can not be made to loosen and leak.Spool and locking cap all adopt stainless steel material, prevent the phenomenon that corrosion rear thread cannot be turned on.
Accompanying drawing explanation
Fig. 1 is the structural representation of this heat pipe outlet valve.
Fig. 2 is the structural representation of the trapezoid cross section circular groove of this heat pipe outlet valve.
Fig. 3 is the structural representation of the metal hollow seal ring of this heat pipe outlet valve.
In Fig. 1,2: 1 is locking cap, 2 is spool, and 3 is metal hollow seal ring, and 4 is valve seat, and 5 is circular groove, and 6 is longitudinal aperture, and 7 is radial hole, and 8 is balance aperture.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 3, the invention provides a kind of heat pipe outlet valve, comprise locking cap 1, spool 2, elastic metallic hollow sealing ring 3, valve seat 4, trapezoid cross section circular groove 5, the endoporus of valve seat 4 is that internal thread coordinates with the outside thread of spool 2, spool 2 and valve seat 4 are all designed with trapezoid cross section circular groove 5, metal hollow seal ring 3 is placed in trapezoid cross section circular groove 5, rotary spool 2 makes it move downward and compresses metal hollow seal ring 3, the thread center of spool 2 has longitudinal aperture 6, another level radial is provided with radial hole 7, longitudinal aperture 6 communicates with radial hole 7, the inner ring of metal hollow seal ring 3 is circumferentially provided with multiple balance aperture 8, radial hole 7 communicates with balance aperture 8, rotary spool 2 makes it move upward, and unclamps metal hollow seal ring 3, now heat pipe gas can be discharged by the longitudinal aperture 6 of spool 2 and radial hole 7.Also be provided with locking cap 1 in the periphery of spool 2, locking cap 1 has screw-thread fit with valve seat 4, and after exhaust completes, rotary spool 2 compresses metal hollow seal ring 3, then screws locking cap 1 pressed spool 2.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
