Abstract
An anti-rust sliding block part for an air conditioner four-way valve includes a metal cavity housing concavely provided with a fluid cavity, wherein a ring of skirt edge is extended horizontally from the metal cavity housing to the four directions, a ring of sealing layer is arranged above the skirt edge, and a ring of buckling edge integrated with the sealing layer and thinner than the sealing layer is arranged on the periphery of the sealing layer; a ring of wrapping edge is also wrapped on the buckling edge on the sealing layer and the periphery of the skirt edge, the wrapping edge buckles the upper side of the buckling edge and the lower side of the periphery of the skirt edge so as to fix the sealing layer and the skirt edge together, and the upper surface of the wrapping edge is lower than that of the sealing layer; and an anti-rust layer is arranged on the surface of the metal cavity housing. The utility model has the benefits that, firstly, by adopting the wrapping edge design, the sealing layer is closely and fixedly wrapped on the skirt edge, the possibility of edge warpage due to temperature variation is little, and the sealing performance is excellent; and secondly, by adopting the anti-rust layer, the possibility that the metal cavity housing rusts is low, so that the service life of the air conditioner four-way valve is not shortened due to the rust slag.
Description
(1) technical field
The utility model relates to a kind of air conditioner parts.
(2) background technique
In cold/hot air-conditioning, the inside all has a special electromagnetic four-way valve to be used for switching the circulation path of refrigeration working medium, with the purpose that reaches refrigeration and heat.As shown in Figure 1, the slide block assembly 1 in the solenoid operated four-way valve of existing technology often adopts and rivets or paste one deck teflon seal sheet on the wire chamber shell, to reach sealing and the effect of sliding flexibly simultaneously.But the teflon seal sheet that directly adopts riveted joint or paste causes the temperature on diaphragm seal both sides not wait, and the easy perk of teflon seal sheet has influence on sealing, and the wire chamber shell gets rusty easily.
(3) summary of the invention
Have the slide block assembly poor sealing performance now in order to overcome, the easy perk of diaphragm seal, the deficiency that the wire chamber shell gets rusty easily, the utility model provides a kind of antirust slider part that is used for the air-conditioning four-way valve of good seal performance.
The technological scheme that the utility model solves its technical problem is: a kind of antirust slider part that is used for the air-conditioning four-way valve; Comprise a wire chamber shell that is concaved with fluid chamber; Said wire chamber shell to around horizontal-extending one circle shirt rim is arranged; Top, described shirt rim is provided with a circle sealing layer, and that described sealing layer periphery is provided with a circle and sealing layer one but thickness is less than the button limit of sealing layer; The button limit on the said sealing layer and the periphery of shirt rim also are enclosed with a circle bound edge, and said bound edge fastens the peripheral downside of said button limit upside and said shirt rim makes said sealing layer and shirt rim be fixed together, and said bound edge upper surface is lower than the sealing layer upper surface; Said wire chamber shell surface is provided with resin layer.Said sealing layer can adopt engineering plastics such as teflon, and perhaps Expanded graphite etc. is commonly used both has sealability, the material that frictional force is smaller again; Said resin layer can be the perhaps coating that is coated with up, can adopt anti-rust metal or rust proof paint, mould leather.Described fluid chamber is used to be communicated with the two-way that the air-conditioning four-way valve is connected.
Further, described sealing layer inner ring limit be provided with a circle and sealing layer one but thickness less than the internal buckle edge of sealing layer; Said wire chamber shell is an affixed fluid chamber shell at the fluid chamber place, and said fluid chamber shell fastens said sealing layer internal buckle edge makes sealing layer and shirt rim be fixed together; Said fluid chamber shell is lower than the sealing layer upper surface topmost; Said fluid chamber shell surface is provided with resin layer.Be provided with the fluid chamber shell and make the good more difficult more leakage of fluid chamber sealing, and the sealing layer design is more firm; Said resin layer can be the perhaps coating that is coated with up, can adopt anti-rust metal or rust proof paint, mould leather.
The utility model is consistent with the slide block assembly of existing technology in use, repeats no more at this.
The beneficial effect of the utility model is: 1, adopt the bound edge design, sealing layer by tightly wrap the thermal change alice that is not easy to catch a cold, good seal performance with the shirt rim.2, adopt resin layer, make the wire chamber shell be not easy to get rusty and form the working life that anvil cinder has influence on the air-conditioning four-way valve.

Fig. 1 is the main valve body cross-sectional schematic of air-conditioning four-way valve.
Fig. 2 is the cross-sectional schematic of an embodiment's antirust slider part in the utility model.
Fig. 3 is the schematic appearance of an embodiment's antirust slider part in the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
In conjunction with accompanying drawing 2 and 3; A kind of antirust slider part that is used for the air-conditioning four-way valve; Comprise a wire chamber shell 3 that is concaved with fluid chamber 2; Said wire chamber shell 3 to around horizontal-extending one circle shirt rim 4 is arranged, top, described shirt rim is provided with the sealing layer 5 of a circle teflon system, that described sealing layer 5 peripheries are provided with a circle and sealing layer one but thickness is less than the button limit 6 of sealing layer; The button limit 6 on the said sealing layer and the periphery of shirt rim 4 also are enclosed with a circle bound edge 7; Said bound edge 7 fastens said button limit 6 upsides and said shirt rim 4 peripheral downsides make said sealing layer 5 be fixed together with shirt rim 4, and said bound edge 7 upper surfaces are lower than sealing layer 5 upper surfaces.
That described sealing layer inner ring limit is provided with a circle and sealing layer one but thickness is less than the internal buckle edge 8 of sealing layer; Said wire chamber shell is an affixed fluid chamber shell 9 at the fluid chamber place, and said fluid chamber shell 9 fastens said sealing layer internal buckle edge 8 makes sealing layer 5 and shirt rim 4 be fixed together; Said fluid chamber shell is lower than the sealing layer upper surface topmost.Be provided with the fluid chamber shell and make the good more difficult more leakage of fluid chamber 2 sealings, and sealing layer 5 designs are more firm.
Said wire chamber shell and fluid chamber shell surface are provided with resin layer.Said resin layer can be the perhaps coating that is coated with up, can adopt anti-rust metal or rust proof paint, mould leather.Described fluid chamber is used to be communicated with the two-way that the air-conditioning four-way valve is connected.
The utility model is consistent with the slide block assembly in the air-conditioning four-way valve of existing technology in use, repeats no more at this.
Present embodiment adopts the bound edge design, sealing layer by tightly wrap the thermal change alice that is not easy to catch a cold, good seal performance with the shirt rim; And the employing resin layer, make the wire chamber shell be not easy to get rusty to form anvil cinder to have influence on air-conditioning four-way valve working life.
