Abstract
The present invention relates to a sealing device of car air-conditioning pipeline, in particular to a device which can greatly reduce slow leakage in the joint of pipeline of air-conditioning system. The invention comprises a vertical sealed joint; the invention is characterized in that in the base of the vertical sealed joint, a head face sealed groove and an O-shaped obturating ring are arranged on the root, and a pipe socket structure is arranged on the joint correspondingly; the O-shaped obturating ring is arranged in a sealed space formed by the head face sealed groove and the pipe socket. The structure can not only overcome slow leakage produced in ellipse which is caused by welding deformation but also overcome slow leakage produced by lacking sealing in head face.
Description
Technical field
The present invention relates to a kind of car air conditioner line seal device, especially a kind ofly can reduce the device that leak slowly air-conditioning system pipeline joint greatly.
Background technique
Leak slowly the air-conditioning duct joint is a fault that occurrence frequency is higher, and each car air conditioner manufacturer does not have a kind of effective way to solve yet to this at present.Solve slowly the problem of leaking, at first must divide the reason of leaking, dolly air-conditioning system pipeline connecting mode roughly has following several at present: end face seal, radial seal, and biradial sealing etc.
The principle of radial seal is that the interference fit by O RunddichtringO and corresponding joint or recessed pressing plate sealing inner cylindrical surface reaches the effect of sealing, its advantage is that the sealing effect of O RunddichtringO is not subjected to respective nut or bolt to tighten the influence of degree in to a certain degree, therefore, O type circle is not fragile; Sealing effect is better relatively.Its shortcoming is because corresponding joint or pressing plate make sealing inner cylindrical surface or boss cylndrical surface produce certain ovality in the process of processing (soldering) easily, thereby the pipeline joint is produced slowly leak.
The principle of end face seal be connect by pipeline between under certain pretightening force of nut and joint, make the interference and reach the effect of sealing between pipeline connects of O RunddichtringO, when pretightening force is appropriate, can play good sealing effect, and leakiness is not influenced by pipe joint or pressing plate ovality, but easily the O RunddichtringO is damaged by pressure when pretightening force incorrect (excessive or too small) or malcompression and cause the pipeline joint to produce leakage slowly.
The biradial sealing is basic identical with the sealing principle of single radial seal, just more radial direction seal rings.
As mentioned above, existing structure still can't be avoided the generation of leaking slowly.
Summary of the invention
The object of the present invention is to provide a kind of terminal sealing structure of air conditioner pipe lines, be used to solve the existing above-mentioned technical problem of existing structure, this structure not only can overcome the leakage slowly that produces when causing ellipse because of welding deformation, can overcome the leakage slowly that the deficiency because of end face seal produces again.
For solving the problems of the technologies described above, the present invention is achieved in that
A kind of terminal sealing structure of air conditioner pipe lines, comprise the radial seal joint, it is characterized in that: on the basis of radial seal joint, increase an end face seal groove and O RunddichtringO at its root, simultaneously corresponding joint increases a bell-mouthed structure, and this O RunddichtringO is installed in by in end face seal groove and the formed seal space of horn mouth.
Described terminal sealing structure of air conditioner pipe lines is characterized in that: this radial seal joint is made up of protruding pressing plate and recessed pressing plate; The projection of this protruding pressing plate is provided with radial seal groove, is equiped with the RunddichtringO in the radial seal groove, and the root of this projection is provided with the end face seal groove; This recessed pressing plate has the mount inlet that the projection with above-mentioned protruding pressing plate is complementary, and a horn mouth is formed on this mount inlet top, and this horn mouth and end face seal groove form an end face seal space, in this end face seal space the O RunddichtringO are installed.
By said structure, the present invention has following useful technique effect:
The pipeline of dolly air-conditioning system can solve the problem that leak slowly the air-conditioning duct joint after connecting the sealing configuration sealing of employing end footpath effectively.Help improving the total quality of dolly air-conditioning system on the one hand, be automobile factory and air-conditioning system factory saving cost; Owing to reduced the leakage rate of refrigeration agent, therefore, help environmental protection on the other hand.

Embodiment
The invention provides the method that a kind of radial seal combines with end face seal-holds and directly seals, can solve the slow leakage problem in pipeline joint effectively.Its structure is on the basis of radial seal joint, increase an end face seal groove and O RunddichtringO at its root, simultaneously corresponding joint increases a bell-mouthed structure, and this O RunddichtringO is installed in by in end face seal groove and the formed seal space of horn mouth.
See also Fig. 1-3, it is the structural representation of a preferred embodiment of the present invention.As shown in the figure: this terminal sealing structure of air conditioner pipe lines has the radial seal joint, and this radial seal joint is made up of protruding pressing plate 1 and recessed pressing plate 2.The projection 11 of this protruding pressing plate 1 is provided with radial seal groove 12, is equiped with RunddichtringO 3 in the radial seal groove 12, and the root of this projection 11 is provided with end face seal groove 13; This recessed pressing plate 2 has the mount inlet 21 that the projection 11 with above-mentioned protruding pressing plate 1 is complementary, and a horn mouth 22 is formed on these mount inlet 21 tops, and this horn mouth 22 forms an end face seal space with end face seal groove 13, in this end face seal space O RunddichtringO 4 is installed.
Be not difficult to find that this end footpath sealing configuration combines radial seal and end face seal, therefore, adopts this kind structure can reduce the leakage slowly of pipeline greatly from this embodiment.In addition, this radial seal joint also can adopt the biradial SEALING FITTING.
