The specific embodiment

Core of the present utility model is to provide a kind of sealing tool of process duct, and this instrument can alleviate that process duct occurs splits leakage phenomenon.Another core of the present utility model is to provide a kind of process duct and a kind of air-conditioner.

In order to make those skilled in the art understand better the technical scheme that the utility model provides, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As Figure 1-10 shows, the sealing tool of the process duct that the utility model embodiment provides, for process duct 21 is sealed to moulding, this sealing tool is similar and structure pliers, it comprises tool body 10 and is installed on the mould on tool body 10, this mould comprises the first mould and the second mould, both are arranged on two relative installation ends of tool body 10, when operating personnel operate this sealing tool, the first mould and the second mould are close gradually, and then clamp process duct 21, realize the clamping sealing to process duct 21.The structure of above-mentioned the first mould can be as Figure 1-4, it comprises die ontology 11 and is installed on the first mouth-sealed portion on die ontology 11, similarly, the second mould comprises die ontology and is installed on the second mouth-sealed portion on die ontology, the first mouth-sealed portion and the second mouth-sealed portion are oppositely arranged, both contact with process duct 21 in the process of docking, thereby apply clamping force to process duct 21.

The key improvements part of the utility model embodiment is, at least one in above-mentioned the first mouth-sealed portion and the second mouth-sealed portion comprises two or more sealing protuberances 12, and has depression 13 between adjacent two sealing protuberances.Above-mentioned sealing protuberance 12 will apply active force at the first mould to process duct 21 with in the relative close process of the second mould, make process duct 21 local deformations, impel the opposing sidewalls of process part 21 mutually close.Particularly, in above-mentioned sealing tool, can adopt the first mouth-sealed portion only or the second mouth-sealed portion to comprise the scheme between 12, two sealing protuberances 12 of two sealing protuberances with depression 13.Certainly, the quantity of sealing protuberance 12 is not limited to two, also can be three or morely, specifically determines according to the actual requirements.

As shown in Fig. 5-7, so that the process duct in air-conditioner is sealed with above-mentioned sealing tool, be example, first adopt this sealing tool once to seal process duct 21, after sealing, unclamp sealing tool, take off snap joint 31, require process duct 21 without obviously revealing; Then from the openend of process duct 21, by glue injection device 32, pour into 0.1～0.3ml anaerobic type structure glue, glue should go deep into 6～8mm in the mouth of pipe, and guaranteeing has enough glues to adhere on secondary sealing width; Finally, after encapsulating, in 1 minute, with above-mentioned sealing tool, process duct 21 is carried out to secondary sealing, when range estimation mouth of pipe place is without clear gap after sealing, adopt electronic leak detector leak detection.

Known by foregoing description, when adopting above-mentioned sealing tool to carry out sealing operation to process duct 21, in process duct 21, will there are at least two sealing plastic zones 211, and there is Transition Zone of Deformation 212 between adjacent two sealing plastic zones 211.Obviously, than the content of introducing in background technology, the sealing tool that the utility model provides makes to have in process duct sealing 211He Transition Zone of Deformation, plastic zone 212, this Transition Zone of Deformation 212 can provide buffering for stress, and then relieve stresses concentration phenomenon, prevent that the position of sealing 211 both sides, plastic zone from forming stress coincidence district simultaneously, thereby reduce the probability that occurs crackle in process duct 21, what alleviate that process duct 21 occurs splits leakage phenomenon, with this, improve the intensity of process duct 21 sealing parts, improve its sealing reliability, Improving The Quality of Products.

For above-mentioned technique effect, also can calculate and verify by formula, specific as follows:

If exist a power to make process duct 21 fractures, must there is a limit stress, i.e. the second strength theory: no matter material is in which kind of stress state, as long as there is brittle fracture, be all the elongation at rupture strain numerical value while reaching simple extension due to the maximum stretching strain in infinitesimal face (line distortion);

When the sealing part of process duct 21 is cutting edge structure, at the sharp corner of cutting edge structure, get infinitesimal oblique section, according to two, to state stress analysis analytic method formula, obtain, the maximum stress on this infinitesimal oblique section is:

${\mathrm{\σ}}_{\max }=\frac{{\mathrm{\σ}}_x+{\mathrm{\σ}}_y}{2}+\frac{1}{2}\sqrt{{({\mathrm{\σ}}_x-{\mathrm{\σ}}_y)}^2+{4\mathrm{\τ}}_{\mathrm{xy}}^2}$

The area of supposing infinitesimal oblique section is S ₀, bring above formula into and obtain:

${\mathrm{\σ}}_{\max }=\frac{F/s_0+F/s_0}{2}+\frac{1}{2}\sqrt{{({F/s}_0-{F/s}_0)}^2+4{\left({F/s}_0\right)}^2}$

σ _max=2F/S ₀

When the sealing tool that adopts the utility model embodiment to provide seals, on 212Chu oblique section, Transition Zone of Deformation, get infinitesimal oblique section, according to two, to state stress analysis analytic method formula, obtain, the maximum stress on this infinitesimal oblique section is:

${\mathrm{\σ}}_{\max }=\frac{{\mathrm{\σ}}_x+{\mathrm{\σ}}_y}{2}+\frac{1}{2}\sqrt{{({\mathrm{\σ}}_x-{\mathrm{\σ}}_y)}^2+{4\mathrm{\τ}}_{\mathrm{xy}}^2}$

The area of supposing infinitesimal oblique section is S ₁, bring above formula into and obtain

${\mathrm{\σ}}_{\max }=\frac{F/s_1+F/s_1}{2}+\frac{1}{2}\sqrt{{({F/s}_1-{F/s}_1)}^2+4{\left({F/s}_1\right)}^2}$

σ _max=2F/S ₁

Known by above-mentioned analysis: in the situation that applying same tensile force f or pressure F, in the structure that the sealing tool that cutting edge structure and the utility model embodiment provide forms, the maximum stress of area of stress concentration is respectively 2F/S ₀and 2F/S ₁, and S ₀< S ₁

Thereby draw:

2F/S ₀＞2F/S ₁

Visible, the sealing tool that the utility model embodiment provides makes the sealing part middle part of process duct 21 increase Transition Zone of Deformation 212, stress can be cushioned in this Transition Zone of Deformation 212, be conducive to the dispersion of stress, stress surface is increased, thereby reduce the maximum stress of area of stress concentration, reach and alleviate the object of splitting leakage phenomenon that process duct 21 occurs.

In order further to strengthen above-mentioned technique effect, in the sealing tool that the utility model embodiment provides, the first mouth-sealed portion and the second mouth-sealed portion include two or more sealing protuberances 12, and have depression 13 between adjacent two sealing protuberances 12.This scheme makes the relative both sides of process duct 21 after sealing, all has larger stress surface, makes the more difficult stress concentration phenomenon that occurs in process duct 21.
