Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-Figure 4, the present embodiment has the end socket of leak detection function, comprise cap body 1, mandrel 2 and elastic baffle 3, one end face of described cap body 1 is formed with blind hole 11, female thread structure (not shown) is formed in described blind hole 11, the other end of described cap body 1 offers the axis hole 12 be communicated with described blind hole 11, described mandrel 2 is inserted in described axis hole 12, described elastic baffle 3 seals and is fixed in described blind hole 11 and shelters from described axis hole 12, and an end of described mandrel 2 is connected on described elastic baffle 3.
Specifically, the cap body 1 that the present embodiment has the end socket of leak detection function can be connected on the Single port of the refrigerant pipe of vaporizer to be hunted leak by female thread structure, carrying out in leak detection testing process to vaporizer, the another port of the refrigerant pipe of vaporizer connects enclosed valve, enclosed valve connects rapid pipe joint and realizes being filled with pressurized gas in vaporizer, after air pressure in vaporizer reaches setting pressure, air pressure will act on elastic baffle 3, make elastic baffle 3 that deformation occur to protrude to axis hole 12 direction, cap body 1 is exposed outside to be with the end of moving mandrel 2, then, stop inflating vaporizer, enclosed valve and cap body 1 will block the two-port of vaporizer, after set time, observe the present embodiment again and have whether the mandrel 2 of the end socket of leak detection function is still outer is exposed at cap body 1 to judge whether vaporizer has leakage point.Concrete, if vaporizer does not have leakage point, air pressure then in vaporizer will remain unchanged, mandrel 2 will be exposed at outside cap body 1 outward all the time, otherwise if vaporizer has leakage point, the air pressure in vaporizer will diminish gradually, elastic baffle 3 will overcome atmospheric pressure and elastic reset, and mandrel 2 is shunk back in cap body 1.Wherein, the middle part of elastic baffle 3 is formed with protruding structure 31, and described protruding structure 31 is formed with draw-in groove 311, and an end of described mandrel 2 is stuck in described draw-in groove 311, and what mandrel 2 can be solid and reliable be stuck in realizes in draw-in groove 311 being connected with elastic baffle 3.In addition, the joint forming station terrace of blind hole 11 and described axis hole 12, described step surface is formed with annular groove 13, the edge card of described elastic baffle 3 is in described annular groove 13, utilize annular groove 13 to block the edge limiting elastic baffle 3, elastic baffle 3 can be made better to coordinate with cap body 1 assemble, play elastic baffle 3 and better seal up axis hole 12.
Further, the end socket that the present embodiment has leak detection function also comprises retainer ring 4 and seal ring 5, and described retainer ring 4 and described seal ring 5 are successively set in described blind hole 11, and described retainer ring 4 is between described seal ring 5 and described elastic baffle 3.Concrete, cap body 1 can be made to be sealedly connected on the refrigerant pipe port of vaporizer by seal ring 5, and retainer ring 4 can be tightened in after on refrigerant pipe at cap body 1, elastic baffle 3 is pressed on step surface by retainer ring 4 closely, realizes elastic baffle 3 and better seals up axis hole 12.Wherein, the edge of elastic baffle 3 is also provided with annular flange 32, and described retainer ring 4 is formed with annular slot 41, and described annular flange 32 is inserted in described annular slot 41, makes retainer ring 4 better can apply balanced pressure to elastic baffle 3.Preferably, the inner ring of retainer ring 4 is formed with capping 42, and described capping 42 offers vent 421, and the middle part of described elastic baffle 3 is formed towards the outstanding protuberance 33 of described capping 42, forms air cavity 34 between described retainer ring 4 and described elastic baffle 3.Concrete, the pressurized gas of vaporizer enter into air cavity 34 by vent 421, and the air pressure in air cavity 34 is more stable, make the present embodiment have the leak detection accuracy of the end socket of leak detection function higher.
The utility model also provides a kind of indoor apparatus of air conditioner, comprise vaporizer, the Single port of the refrigerant pipe of described vaporizer is provided with enclosed valve, also comprises the above-mentioned end socket with leak detection function, described in there is leak detection function end socket be connected on the another port of the refrigerant pipe of described vaporizer.
The leak hunting method of the indoor apparatus of air conditioner that the utility model provides, concrete grammar is: in vaporizer, inject pressurized gas by enclosed valve, after vaporizer internal pressure reaches setup pressure value, under the influence of air pressure, deformation makes the end of mandrel expose outside cap body by the elastic baffle had in the end socket of leak detection function, then, stop injecting pressurized gas in vaporizer; If vaporizer is after setting duration, the end of mandrel still exposes outside cap, and this is external, then judge that vaporizer is without leak source, otherwise, then judge that vaporizer has leak source.
End socket and the indoor apparatus of air conditioner of what the utility model provided have leak detection function, by arranging mandrel and elastic baffle in cap body, deformation can be there is in elastic baffle under the effect be stressed, thus band moving mandrel moves in axis hole, and cap body can by being screwed on the refrigerant pipe of vaporizer, carrying out in leak detection process, by injecting pressurized gas in vaporizer, there is deformation under the influence of air pressure and band moving mandrel spilt cap body in elastic baffle, vaporizer injects pressurized gas after certain hour, if vaporizer has the place of leakage, pressure in vaporizer will reduce, thus elastic baffle resets under its own resilient effect, mandrel is made to be contracted in cap body, expose just can complete easily when making operator by observing mandrel and vaporizer is hunted leak, thus hunt leak without the need to vaporizer being placed in helium inspection vacuum box, the process simplifying leak detection improves efficiency.In addition, before indoor apparatus of air conditioner dispatches from the factory or when locating to install to user, all can judge whether the vaporizer of indoor apparatus of air conditioner is damaged in transport or storing process by the end socket with leak detection function intuitively, thus avoid, by online to the indoor apparatus of air conditioner and outdoor unit that there are quality problems and cause the refrigerant in outdoor unit to waste, effectively raising the outgoing of indoor apparatus of air conditioner.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
