Abstract
The utility model relates to a stainless steel corrugated pipe which is used for connection in a wateway. The exiting shallow annular stainless steel corrugated pipe is difficult to pass through the IAPMO test of the united states. The utility model comprises a stainless steel corrugated section and narrowing necks, wherein the narrowing necks are positioned at both ends of the corrugated section. The utility model is characterized in that the stainless steel corrugated section which forms a spiral shape is connected into one body with the narrowing necks at both of the two ends of the stainless steel corrugated section; the outer diameter of each of the narrowing necks is less than the outer diameter of the corrugated section. The utility model enables adjacent ripples to become a continuous passage. The resistance to which water is subjected when flowing across the corrugated section is little. Simultaneously, the through diameter of the corrugated pipe is effectively increased and the pressure which is produced is decreased. The utility model can full reach the standards of the IAPMO test of the united states.
Description
Technical field
The utility model is a kind of water corrugated stainless steel tubing that the water route connects that is used for.
Background technique
In connecting, water flowing devices such as cleaners and polishes, water heater, central air-conditioner fan coil unit soft connector extensively adopt corrugated stainless steel tubing.Shallow ring stainless steel bellows is generally adopted by present domestic manufacturer because it is easy to process, manufacturing efficiency is high, cost is low.China does not still have the GB and the rower of this product at present, some producer's accepted standards are mainly American I APMO testing standard, and American I APMO has increased the test event that bellows pressure is fallen in new testing standard, its index request is higher, there are following two problems in existing shallow ring stainless steel bellows: one, because nut is to be enclosed within on the ripple external diameter, the latus rectum of pipe is restricted; Two, since annular corrugated be at interval setting, adjacent ripple does not connect, the resistance that current are subjected to when flowing through bellows segment is big, is difficult to by this test.
The model utility content
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, provide a kind of bellows segment helical corrugated stainless steel tubing, adjacent ripple is connected, reduce the resistance that current are subjected to when flowing through bellows segment, adopt two ends necking down structure simultaneously, improve the latus rectum of pipe, effectively reduce pressure and fall, to reach American I APMO testing standard.
For this reason, the utility model adopts following technological scheme: the water corrugated stainless steel tubing, comprise stainless steel ripple section and the necking down that is positioned at its two ends, and it is characterized in that described stainless steel ripple section twist, and be connected as a single entity with the necking down at its two ends, the external diameter of necking down is less than the external diameter of bellows segment.Spiral bellows segment connects adjacent ripple, becomes a continuous passage, and (Buddhist nun) is little for the resistance that current are subjected to when flowing through bellows segment, helps reducing pressure and falls.Because the external diameter of ripple depends on the size of nut, after the necking down processing, under identical nut specification, but can increase the size of outside diameter of bel, further reduce pressure and fall, can reach American I APMO testing standard fully.
Described water corrugated stainless steel tubing, the outer end of necking down have a bulge loop that is connected as a single entity with it, are with the nut of a band bottom outlet in the necking down, the aperture of bottom outlet is less than the external diameter of bulge loop, prevent that nut is drawn out from bulge loop, the bulge loop outside is provided with a rubber pad, reaches the sealing effect of necking down end face.
Described water corrugated stainless steel tubing has an insulating bushing that runs through the nut bottom outlet between necking down and nut, insulating bushing can be made with plastics or other insulating material, and insulating effect electrifies.
The utlity model has following beneficial effect: spiral bellows segment makes adjacent ripple become a continuous passage, the resistance that current are subjected to when flowing through bellows segment is little, effectively increase the latus rectum of bellows simultaneously, the pressure of generation falls little, can reach American I APMO testing standard fully; Avoided conducting electricity between nut and necking down, prevented the generation of electric shock accidents, be specially adapted in the electric water heater.
Below in conjunction with drawings and Examples the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Water corrugated stainless steel tubing as shown in Figure 1, stainless steel ripple section 1 and are connected as a single entity with the necking down 2 at its two ends twist, and the external diameter of necking down 2 is less than the external diameter of bellows segment 1.There is a bulge loop that is connected as a single entity with it 3 outer end of necking down 2, be with an insulating bushing 6 that runs through the nut bottom outlet in the necking down 2, be with the nut 4 of a band bottom outlet on the lining 6, the aperture of nut 4 bottom outlets is less than the maximum outside diameter of lining 6, also less than the external diameter of bulge loop, bulge loop 3 props up the end face of lining 6 and prevents that lining 6 and nut 4 from being pulled, and is positioned at the bulge loop outside and is provided with a rubber pad 5.
Claims (3)
1, water corrugated stainless steel tubing, comprise stainless steel ripple section (1) and be positioned at the necking down (2) at its two ends, it is characterized in that described stainless steel ripple section (1) twist, and be connected as a single entity that the external diameter of necking down (2) is less than the external diameter of bellows segment (1) with the necking down (2) at its two ends.
2, water corrugated stainless steel tubing according to claim 1, there is a bulge loop that is connected as a single entity with it (3) outer end that it is characterized in that necking down (2), be with the nut (4) of a band bottom outlet in the necking down (2), the aperture of bottom outlet is less than the external diameter of bulge loop, and bulge loop (3) outside is provided with a rubber pad (5).
3, water corrugated stainless steel tubing according to claim 1 and 2 is characterized in that having between necking down (2) and nut (4) insulating bushing (6) that runs through the nut bottom outlet.
