Abstract
The invention discloses a kind of air-conditioning duct valve seat and the attachment structure of pipe fitting, including valve seat and pipe fitting, pipe fitting mounting hole is provided with the valve seat, it is characterized in that the side of the pipe fitting is pressing plane, the pipe fitting is located in pipe fitting mounting hole, and flattens plane upwards, and the valve base inner wall above the pipe fitting mounting hole is provided with a seal groove, sealing ring is set in seal groove, and sealing ring is in close contact with the pressing plane of pipe fitting.Valve seat can be installed with the later stage using this design using the present invention, its mounting process is convenient, and flow is simple, and environmental protection, operator's good work environment, it is corrosion-free without needing gas and solder flux as flame welding.Even if leakage, it is only necessary to change a valve seat and install and can just be scrapped without whole pipe fitting with solve problem, so as to substantially reduce the manufacturing cost of product.
Description
Invention field
Design the present invention relates to pipelines of automobile air conditioner valve seat is related to aluminium section bar to be connected with pipe fitting, and in particular to the attachment structure of a kind of air-conditioning duct valve seat and pipe fitting.
Background technology
In pipelines of automobile air conditioner production, present valve seat is all to be welded to connect valve seat and pipe fitting using flame, once valve seat welding is revealed, repair welding qualification rate is low, of poor quality, during work consuming, so that whole pipe is scrapped, because whole pipe fitting had previously been permitted
Multi-processing technique occurs, along with often there is many annexes to be mounted above on pipe fitting, once whole pipe fitting is scrapped, that is to say, that
Other annexes and previous work flow are all scrapped, and than larger, Product processing cost is greatly increased for such mass loss.
The content of the invention
It is an object of the invention to provide a kind of pipelines of automobile air conditioner valve seat and the attachment structure of pipe fitting, valve seat can be installed with the later stage using this attachment structure, its mounting process is convenient, flow is simple, and environmental protection, operator's good work environment, it is corrosion-free without needing gas and solder flux as flame welding.
To achieve these goals, technical scheme is as follows：A kind of attachment structure of pipelines of automobile air conditioner valve seat and pipe fitting, including valve seat and pipe fitting, pipe fitting mounting hole is provided with the valve seat, it is characterized in that the side of the pipe fitting is pressing plane, the pipe fitting is located in pipe fitting mounting hole, and flattens plane upwards, and the valve base inner wall above the pipe fitting mounting hole is provided with a seal groove, sealing ring is set in seal groove, and sealing ring is in close contact with the pressing plane of pipe fitting.Valve seat lower end is provided with latch centre bore.
Valve seat can be installed with the later stage using this design using the present invention, its mounting process is convenient, and flow is simple, and environmental protection, operator's good work environment, it is corrosion-free without needing gas and solder flux as flame welding.Even if leakage, it is only necessary to change a valve seat and install and can just be scrapped without whole pipe fitting with solve problem, so as to substantially reduce the manufacturing cost of product.

Specific embodiment
The present invention is a kind of pipelines of automobile air conditioner valve seat and the attachment structure of pipe fitting.
Fig. 1 show the structural representation of pipelines of automobile air conditioner valve seat of the invention, and according to a particular embodiment of the invention, the pipelines of automobile air conditioner valve seat is plastic seat 1.Pipe fitting mounting hole 2 is provided with the plastic seat 1, the size of mounting hole is generally tube outer diameter full-size+0.1mm, the valve base inner wall of the top of pipe fitting mounting hole 2 is provided with seal groove 3, the top of seal groove is valve element mounting hole 4, the top of pipe fitting mounting hole 2 connects with valve element mounting hole 4, latch centre bore 5 is then provided with the lower seat of pipe fitting mounting hole, the effect of this latch centre bore is connected with and is fastened by this centre bore after valve seat and pipe fitting connection.Fig. 2 is the attachment structure schematic diagram of plastic seat 1 and pipe fitting 6.Valve element 7 is provided with valve element mounting hole, the side of pipe fitting 6 is pressing plane, the pipe fitting is located in pipe fitting mounting hole, and it is upward to flatten plane, sealing ring 8 is set in valve base inner wall seal groove 3, sealing ring 8 is contacted with the pressing plane squeezed tight of pipe fitting 6, i.e., the pressing plane of pipe fitting 6 forms sealing surface with the contact position of sealing ring 8.
To the distance of following latch centre bore, both must have strict requirements to seal groove, and the size of this distance determines the tightness degree of sealing ring.According to a preferred embodiment of the invention, the bottom of the seal groove is L1 to the centre distance of latch centre bore, and sealing ring line footpath is D1, and the distance of the sealing surface of pipe fitting plane to latch centre bore is L2, then we require L1/（D1+L2）=90%±0.2%.
Claims (2)
