Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of automotive air-conditioning system sealing configuration.
Background technique
Existing automotive air-conditioning system sealing configuration adopts axial seal usually, namely the seal ring that one external diameter is greater than interface internal diameter is set in the bottom of joint, allow interface internal diameter contact also crush seal circle with seal ring upper surface during installation and make its deformation, thus reach the effect at axial seal connection inlet place, the amount of compression of this kind of sealing means to seal ring is little, in installation process, seal ring can not produce galling, and sealing is also comparatively even, but there is certain leakage situation, reason be mainly automobile particularly large engineering vehicle can produce the high and vibration that amplitude is larger of frequency in the course of the work, base press plate be connected pressing plate and there will be slight deformation in above process and cause the spacing between two pressing plates to become large, the deformation quantity of seal ring reduces, sealing declines thus produces and leaks.And in the sealing in other field, use radial seal structure in addition, namely seal ring is set between two sheathed parts, between the outer wall that the interference of sealing circle is connected to two parts and inwall, thus reach the effect of radial seal, if but the magnitude of interference of this kind of sealing means seal ring is excessive, seal ring can be damaged in installation and using process, magnitude of interference is too small does not have leak preventing effect, therefore plant seal ring when mounted because of unbalance stress simultaneously, the deformation of seal ring is also uneven, seal ring is caused to overstock in one direction excessive and too small to opposite deformation, leakage can be caused equally.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of engineering truck air-conditioning system that can effectively prevent by vibrating the leakage caused, and working life and stability are all better than the sealing configuration of prior art.
The utility model solves the problems of the technologies described above adopted technological scheme:
A kind of automotive air-conditioning system sealing configuration, by base press plate be connected pressing plate and form, described connection pressing plate is provided with pressing plate joint, described base press plate is provided with the pressing plate interface matched with pressing plate joint, described pressing plate joint is provided with the first groove and the second groove, described first groove is arranged on and the pressing plate tip side being connected pressing plate connection, and described second groove is arranged on and is connected between the pressing plate tip side of pressing plate connection and the pressing plate joint the other end; Described first groove and the second groove are respectively arranged with axial sealing ring and radial direction seal ring, and the external diameter of described axial sealing ring and radial direction seal ring is greater than the internal diameter of pressing plate interface.Make between joint and interface, to reach radial and axial double-sealing by arranging Double seal ring structure, radial direction seal ring had both prevented between two pressing plates because spacing becomes the leakage possibility produced greatly, also there is frictional force because of it and between joint and interface, play the function preventing joint from getting loose in interface; The setting of axial sealing ring can effectively prevent axial sealing ring in micro-leakage of installing and occur because deformation is uneven in using process, simultaneously also because the setting of radial direction seal ring makes connector interface position comparatively fixing, in use extruding force is comparatively even for it, and the stability of axial sealing ring and working life are obtained for larger lifting; The setting of groove simultaneously defines axial sealing ring and the displacement of radial direction seal ring when installing and use, and make two seal ring deformation more even, in using process, stability is also higher.
As preferably, the external diameter of described axial sealing ring is greater than the external diameter of described radial direction seal ring.Radial direction seal ring external diameter and interface minor diameter fit, and axial sealing ring need cover the generation that whole interface can prevent from revealing, the external diameter that therefore external diameter of axial sealing ring is greater than described radial direction seal ring makes seal arrangement be easier to install and good leak-proof effect.
Further, the external diameter of described first groove is greater than the external diameter of described second groove.External diameter because of axial sealing ring is greater than the external diameter of described radial direction seal ring, and the external diameter that therefore external diameter of the first groove is greater than described second groove is more convenient for installing and spacing.
Further, described axial sealing ring and radial direction seal ring are separated by setting.If axial sealing ring directly contacts with radial direction seal ring, in Long-Time Service process, two seal rings bonding can affect respective shape and deformation quantity, be therefore the separated by stability and working life that arrange and can improve sealing configuration mutually.
Further, described second groove away from arranging near the pressing plate joint the other end with the pressing plate tip side being connected pressing plate connection, position pressing plate joint shaft upwards 1/2 to 1/3 between.Radial direction seal ring is sealed in the intermediate portion integral seal structure better effects if of joint, but because radial direction seal ring in installation process can be subject to the downward pressure of interface and frictional force effect, to be therefore arranged on position effect in the middle part of joint or top better for radial direction seal ring.
As preferably, described pressing plate interface is provided with arc wide-mouth with the end of pressing plate joint connection.When arc wide-mouth makes radial direction seal ring be fit into interface, frictional force increases gradually, makes the deformation of radial direction seal ring in installation process evenly and conveniently to install.
Further, the external diameter of described axial sealing ring is less than or equal to the maximum inner diameter of arc wide-mouth.Make axial sealing ring can be fit into arc wide-mouth completely, fitted arc wide-mouth completely in the surface of axial sealing ring, sealing effect is better.
The utility model compared with the existing technology has the following advantages and effect: the setting of axial sealing ring and radial direction seal ring makes to reach radial and axial double-sealing between joint and interface, working life and stability higher; By sealing configuration, setting position with further increase life-span and stability with the improvement of Interference fit, and be more convenient for installing, in installation process, the loss of sealing configuration is also less.
