Description
Technical field
The present invention relates to rapid connector component.
Background technique
In liquid-cooling system, the critical component of heat radiation is cold drawing, during use by heater members near being mounted on cold drawing, thus realize carrying out heat exchange to obtain the object of dispelling the heat with the cooling liquid that flows in cold drawing, therefore the planeness of cold drawing is a key parameter of cold drawing.Need during actual use to use rapid connector component logical cooling liquid in cold drawing, rapid connector component comprises adaptive rapid pipe joint male and rapid pipe joint female, cold drawing arranges the rapid pipe joint male with cold drawing inner space, in rapid pipe joint male, rapid pipe joint female is connected during debugging, by rapid pipe joint female, rapid pipe joint male injects cooling liquid in the inner chamber of cold drawing, performing leak test and thermal performance test are carried out to the cooling liquid of cold drawing inside, after test passes, rapid pipe joint male and rapid pipe joint female are disconnected, cold drawing and rapid pipe joint male entirety warehouse-in store or transport.Existing rapid pipe joint male is " a kind of rapid connector component and one-way sealing joint thereof " disclosed in Chinese patent CN101581392A, rapid connector component comprises rapid pipe joint male and rapid pipe joint female, it is bayonet end that rapid pipe joint female comprises front end, rear end is the female housing of conduit connection end, the female fluid passage running through female housing is along the longitudinal direction provided with in female housing, the middle part of female fluid passage is provided with female spool, the external elastic of female spool is equipped with Moveable seal cartridge, female spring is when free state, female spool and Moveable seal cartridge are sealed and matched with shutoff female fluid passage, it is bayonet end that rapid pipe joint male comprises front end, rear end is the male housing of conduit connection end, the male fluid passage running through male housing is along the longitudinal direction provided with in male housing, male fluid passage Elastic is equipped with male spool, when male spring is in free state, male spool coordinates with shutoff male fluid passage with male housing seal, in rapid pipe joint male, during the non-grafting of rapid pipe joint female, by spring action Moveable seal cartridge shutoff female fluid passage, male spool shutoff male fluid passage, when rapid pipe joint male, during the grafting of rapid pipe joint female, move after male housing pushing tow Moveable seal cartridge makes Moveable seal cartridge, move after female spool pushing tow male spool makes male spool, conducting female fluid passage is formed between such female spool and male housing, the communicating passage of male fluid passage, cooling liquid can through rapid pipe joint female, rapid pipe joint male injects cold drawing, after a test, rapid pipe joint female is pulled out by rapid pipe joint male, again move forward and shutoff male fluid passage by male spring action male spool.Existing this rapid pipe joint male Problems existing is: during due to debugging cold drawing, cold drawing inside can be full of cooling liquid, after debugging terminates, normally directly disconnect rapid pipe joint female and rapid pipe joint male, now cold drawing inside is still full of cooling liquid, if directly warehouse-in is deposited or is transported, when the temperature increases, cooling liquid can expand, this expansion is inevitable and quite strong, the cooling liquid volume expanded increases, when cooling liquid is when being full of seal container, then can show as pressure sharply to increase, light then cold drawing Surface deformation can be caused, bulge, heavy then cause cold drawing to break, leakage, these two kinds of situations all can directly cause scrapping of cold drawing.
Summary of the invention
The object of the present invention is to provide a kind of rapid connector component, can not self-relieving problem to solve rapid pipe joint male in prior art.
In order to solve the problem, technological scheme of the present invention is:
Rapid connector component, comprise rapid pipe joint female and rapid pipe joint male, rapid pipe joint female comprises female housing and is arranged at the female spool in female housing, the peripheral guiding movement of female spool is equipped with Moveable seal cartridge, rapid pipe joint male comprises the male housing of front end for Moveable seal cartridge described in pushing tow, in the male fluid passage of male housing, guiding movement is equipped with front end for by the male spool of described female spool pushing tow, the pressure release passage for being communicated with described male fluid passage and outside atmosphere is provided with in male spool, pressure release passage comprises the liquid-through hole section be connected with described male fluid passage and the mounting hole section be connected with described outside atmosphere, in mounting hole section, guiding movement is equipped with closeouts, male spool is provided with for applying elastic acting force to make the pressure release spring of liquid-through hole section described in described closeouts shutoff to described closeouts, in described closeouts, be provided with on male spool or between closeouts with male spool for departing from the rear conductive channel being communicated with described liquid-through hole section and mounting hole section in closeouts and described liquid-through hole section.
Described pressure release passage runs through described male spool along the longitudinal direction.
Described closeouts is steel ball, and Spielpassung between the hole wall of described steel ball and described mounting hole section, described conductive channel is formed by the gap between described steel ball and the hole wall of mounting hole section.
Aperture, one end Yan Chu that described liquid-through hole section is adjacent with described mounting hole section is provided with for coordinating with described steel ball sealing and realizes the seal ring of liquid-through hole section described in steel ball shutoff.
Described male spool comprises the installation sleeve that axis extends along the longitudinal direction and the insert body coordinated with described male housing guiding movement, installation sleeve spinning is in described insert body, described liquid-through hole section is arranged on described insert body, and described mounting hole section is made up of the endoporus of described installation sleeve.
The endoporus of described installation sleeve is shoulder hole, the aperture section arranged before and after shoulder hole has and macropore section, described closeouts guiding movement is assemblied in described macropore section, and described spring is arranged in described aperture section, and the front end varus of described aperture section has the spring seat of loop configuration.
Beneficial effect of the present invention is: when the rapid pipe joint female grafting of rapid pipe joint male not with adaptation, male spool shutoff male fluid passage, under pressure release acting force of the spring, closeouts also can the liquid-through hole section of shutoff pressure release passage, when this rapid pipe joint male and adaptive rapid pipe joint female grafting, move after the Moveable seal cartridge of the male housing pushing tow rapid pipe joint female of rapid pipe joint male makes Moveable seal cartridge, the male spool of the male of rapid pipe joint is simultaneously moved backwards by the female spool pushing tow of rapid pipe joint female, so just rapid pipe joint female can be passed through, male injects cooling liquid in corresponding cold drawing, after cold drawing has been detected, pull out rapid pipe joint female, if the cooling liquid in cold drawing is heated and volume increases, cooling liquid will give closeouts active force, when this active force is greater than the active force of pressure release spring, closeouts will depart from liquid-through hole section, now cooling liquid can through conductive channel, mounting hole section removal, realize the releasing pressure automatically of rapid pipe joint male, thus ensure that cold drawing pressure off guard damages by pressure.
