Abstract
The utility model discloses the linkage structure of a kind of pipelines of automobile air conditioner valve seat and pipe fitting, comprise valve seat and pipe fitting, pipe fitting mounting hole is provided with in described valve seat, it is characterized in that the side of described pipe fitting is for flattening plane, described pipe fitting is positioned at pipe fitting mounting hole, and flattens plane upwards, and the valve base inner wall above described pipe fitting mounting hole is provided with a seal groove, in seal groove, seal ring is set, the pressing plane close contact of seal ring and pipe fitting.Use the utility model to use this design the later stage can install valve seat, its mounting process is convenient, and flow process is simple and easy, and environmental protection, operator's good work environment, needs gas and solder flux without the need to resembling flame welding, corrosion-free.Even if leak, only need to change a valve seat installation and just can deal with problems, need not scrap by whole pipe fitting, thus greatly reduce the manufacture cost of product.
Description
Invention field
The design that the utility model relates to pipelines of automobile air conditioner valve seat relates to aluminium section bar and is connected with pipe fitting, is specifically related to the linkage structure of a kind of pipelines of automobile air conditioner valve seat and pipe fitting.
Background technique
In pipelines of automobile air conditioner is produced, present valve seat is all use flame to be welded to connect valve seat and pipe fitting, once valve seat welding is revealed, repair welding up-to-standard rate is low, of poor quality, during work consuming, to such an extent as to whole pipe is scrapped, due to the previously existing many processing technology generations of whole pipe fitting, add and pipe fitting often has above many annexes are arranged on, once whole pipe fitting is scrapped, that is other annex and previous work flow are all scrapped, such mass loss is larger, and Product processing cost increases greatly.
Model utility content
The purpose of this utility model is the linkage structure providing a kind of pipelines of automobile air conditioner valve seat and pipe fitting, use this linkage structure the later stage valve seat can be installed, its mounting process is convenient, flow process is simple and easy, and environmental protection, operator's good work environment, without the need to resemble flame welding need gas and solder flux, corrosion-free.
To achieve these goals, the technical solution of the utility model is as follows: the linkage structure of a kind of pipelines of automobile air conditioner valve seat and pipe fitting, comprise valve seat and pipe fitting, be provided with pipe fitting mounting hole in described valve seat, it is characterized in that the side of described pipe fitting is for flattening plane, described pipe fitting is positioned at pipe fitting mounting hole, and flatten plane upwards, valve base inner wall above described pipe fitting mounting hole is provided with a seal groove, arranges seal ring in seal groove, the pressing plane close contact of seal ring and pipe fitting.Valve seat lower end is provided with latch center hole.
Use the utility model to use this design the later stage can install valve seat, its mounting process is convenient, and flow process is simple and easy, and environmental protection, operator's good work environment, needs gas and solder flux without the need to resembling flame welding, corrosion-free.Even if leak, only need to change a valve seat installation and just can deal with problems, need not scrap by whole pipe fitting, thus greatly reduce the manufacture cost of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of valve seat.
Fig. 2 is the linkage structure schematic diagram of valve seat and pipe fitting.
Embodiment
The utility model is the linkage structure of a kind of pipelines of automobile air conditioner valve seat and pipe fitting.
Figure 1 shows that the structural representation of pipelines of automobile air conditioner valve seat of the present utility model, according to specific embodiment of the utility model, described pipelines of automobile air conditioner valve seat is plastic seat 1.Pipe fitting mounting hole 2 is provided with in described plastic seat 1, the size of mounting hole is generally tube outer diameter overall dimensions+0.1mm, valve base inner wall above pipe fitting mounting hole 2 is provided with seal groove 3, the top of seal groove is spool mounting hole 4, described pipe fitting mounting hole 2 top is communicated with spool mounting hole 4, the lower seat of pipe fitting mounting hole is then provided with latch center hole 5, and the effect of this latch center hole to be connected with bolt by this center hole after valve seat is connected with pipe fitting and fastening.
Fig. 2 is the linkage structure schematic diagram of plastic seat 1 and pipe fitting 6.Spool 7 is provided with in spool mounting hole, the side of pipe fitting 6 is for flattening plane, described pipe fitting is positioned at pipe fitting mounting hole, and flatten plane upwards, seal ring 8 is set in valve base inner wall seal groove 3, seal ring 8 contacts with the pressing plane squeezed tight of pipe fitting 6, and namely the pressing plane of pipe fitting 6 and seal ring 8 contacting point form sealing surface.
Seal groove is to the distance of latch center hole below, and both must have strict requirement, and the size of this distance determines the tightness degree of seal ring.According to preferred embodiment of the present utility model, the bottom of sealing ring recess is L1 to the centre distance of latch center hole, seal ring wire diameter is D1, and the sealing surface of pipe fitting plane is L2 to the distance of latch center hole, and so we require L1/(D1+L2)=90% ± 0.2%.
Claims (2)
1. the linkage structure of a pipelines of automobile air conditioner valve seat and pipe fitting, comprise valve seat and pipe fitting, pipe fitting mounting hole is provided with in described valve seat, it is characterized in that the side of described pipe fitting is for flattening plane, described pipe fitting is positioned at pipe fitting mounting hole, and flattens plane upwards, and the valve base inner wall above described pipe fitting mounting hole is provided with a seal groove, arrange seal ring in seal groove, seal ring contacts with the pressing plane squeezed tight of pipe fitting.
2. linkage structure as claimed in claim 1, it is characterized in that being provided with spool in valve seat, valve seat lower end is provided with latch center hole.
