Abstract
The utility model provides an aluminum stop valve, comprising a joint pipe of two layers, for connecting an external pipe, wherein one layer is made from aluminum and another layer is made from copper. Preferred, the inner layer is made from copper and the outer layer is made from aluminum. The stop valve with the joint pipe is conveniently to connect other copper pipes, and the mechanical strength and corrosion resistance of the joint pipe are improved.
Description
Technical field
The utility model relates to the stop valve that air-conditioning equipment uses.
Background technique
Pipeline fitting in the air-conditioning equipment is mainly by copper production, but along with the rising steadily of copper valency, existing increasing air-conditioning equipment accessory changes by other cheap made.A large amount of in the market stop valves that occur by the metallic aluminium manufacturing.As shown in Figure 1, the adapter 1 of this kind aluminium matter stop valve 2 bottoms welding all is an aluminium matter tubing, though adopt aluminium matter tubing bigger decline to be arranged for product cost, but the follow-up use technology to product causes suitable difficulty because stop valve usually need with air-conditioning in pipeline, other accessories (as one-way valve, baffler, capillary tube etc.) of still making by red copper weld combination mutually.Red copper is compared with aluminum pipe on temperature rise at material, the fusing point and is differed greatly, and color can not change when aluminum pipe was heated, welding personnel is difficult to judge with eyes the temperature coordination situation of aluminum pipe, copper spare, very easily cause aluminum pipe to melt and the copper pipe temperature does not reach the phenomenon of technological requirement as yet, cause aluminum pipe and red copper part to be difficult to direct welding.In addition, can not reach quality requirement by welding resulting adhesive strength between aluminium and the copper, cause this aluminium matter stop valve patented technology can not be applied to veritably produce.
On the material property characteristics, also there are certain defective in the anti-leakage ability of aluminium matter tubing, anti-vibration breakdown strength, anti-corrosion capacity simultaneously.
The model utility content
For solving the problems of the technologies described above, the utility model improves existing aluminium stop valve, that is, the main body of aluminium stop valve is constant, and changes the structure of its adapter, and original simple aluminum pipe or simple copper pipe are replaced with a kind of copper aluminum composite pipes.This composite pipe is divided into two-layer, and internal layer is a copper, and skin is an aluminium.
The adapter of stop valve is used after the copper aluminum composite pipes, can guarantee that copper aluminum composite pipes inwall copper pipe directly contacts with air-conditioning duct, accessory copper pipe when welding, does not have dissimilar metal welding phenomenon; Simultaneously copper aluminum composite pipes inwall copper pipe is consistent with the temperature rise of air-conditioning duct, accessory copper pipe, makes the thawing of welding filler metal, is consistent with the combination of pipeline copper material, can fully guarantee welding procedure and weld strength.
Adopt copper aluminum composite pipes simultaneously, adopt full aluminium matter tubing to improve a lot in than original technology in tensile strength, anti-vibration breakdown strength, on anticorrosive.Adopt copper aluminum composite pipes as the aluminium stop valve of taking over,, except satisfying its original function, also improved product performance by the improvement of on original material, carrying out, more corrosion-resistant.
Description of drawings
Fig. 1 illustrates the stop valve that the single metal of existing employing is taken over.
Fig. 2 illustrates the stop valve that copper aluminum composite pipes is taken over that has of the present utility model.
Embodiment
The main difference point of stop valve shown in Fig. 2 and prior art is that the adapter 1 of joining with valve body 2 has double layer construction.Wherein, internal layer 11 is a copper, and outer 12 is aluminium.Adapter 1 is connected with valve body 2 by welding.
When making stop valve shown in Figure 2, turning one aluminium blank at first is to obtain an aluminium valve seat 2.After 1 enlarging is finished to copper aluminum composite pipes simultaneously, copper aluminum composite pipes 1 is put into the adapter hole of valve seat again and welded, after welding is finished valve body surface is handled totally, assembling aluminium spool 3, snap ring, O shape are enclosed in valve body.
As an alternative, the internal layer of adapter 1 can adopt aluminium, skin can adopt copper, for this situation, adapter need contact with valve body by inwall, and the other end then need be made reducing (with shown in Figure 2 opposite), when this is taken over when being connected with a copper pipe, this reducing enters this copper pipe, then by being welded to connect.Certainly, this mode of execution is compared with previous embodiment and is not preferred.
More than be to be used for the purpose of illustration and description to embodiment of the present utility model and embodiment's description, though the utility model is illustrated, should not regard as restriction of the present utility model by some previous embodiment.They be not detailed or restriction the utility model in disclosed precise forms.Therefore, scope of the present utility model comprises field as this paper is disclosed, and by claims with and equivalence replace contained.
Claims (3)
1. aluminium stop valve that is used for air-conditioning equipment, it comprises an adapter, it is characterized in that, the adapter of described stop valve is the double-deck composite pipe of copper aluminium.
2. aluminium stop valve according to claim 1, wherein, the internal layer of described composite pipe is a copper, skin is an aluminium.
3. aluminium stop valve according to claim 2, wherein, described composite pipe is soldered in the valve port of described stop valve by its skin.
