Abstract
The utility model belongs to a pipe joint, particularly a shape memory alloy pipe joint used for pipeline connection. A pipe joint body (1) is a casing pipe, wherein, the inner surface of the casing pipe is provided with a convex ridge (11). The shape of the convex ridge (11) is a trapezoid, a tip tooth shape, a square, or a circular arc shape. The shape memory alloy pipe joint used for pipeline connection uses a shape memory effect to cause a pipe joint and a connected pipe to form large interference fit to realize connection. The shape memory alloy pipe joint used for pipeline connection has the advantages of high connection intensity, good sealing performance, corrosion resistance, convenient operation, light weight, little space, etc.
Description
Background technique
The utility model belongs to a kind of pipe joint, is specially a kind of marmem pipe joint that pipeline connects that is used for.
Technical field
Pipe connecting method commonly used is welding, bonding or mechanical whorl connection.The shortcoming of welding method is an inconvenient operation, the connection between the especially inapplicable foreign material.The shortcoming of adhering method is that join strength is low, and sealing is poor.The shortcoming of mechanical whorl connecting means is influenced by extraneous factor such as impact, vibration, corrosion etc. to cause the decreased performance that connects, and its used part is many, and it is big to take up space.
The model utility content
The purpose of this utility model be to provide a kind of easy to operate, join strength is high, the marmem pipe joint of good airproof performance.
The technical solution of the utility model is that the marmem pipe joint body is the sleeve pipe of inner surface belt convex ridge;
Described ridge-shape is trapezoidal, sharp-tooth shaped, square or circular arc etc.; The quantity of described convex ridge is in 2～6 scopes; The internal diameter of described pipe joint body is in Φ 3～100mm scope, and length is in 6～200mm scope;
Memory alloy pipe joint of the present utility model can adopt the TiNiNb alloy to make.
The utility model is a kind of marmem short sleeve, and its working principle is based on the shape memory effect of memory alloy.The initial inside diameter of memory alloy short sleeve is less than the external diameter of connected tube, and hole enlargement at low temperatures makes the internal diameter of memory alloy pipe joint bigger slightly than the external diameter of connected tube.During assembling, two connected tubes behind the insertion location, two ends of memory alloy pipe joint, will be recalled alloy pipe joint and heated up, because shape memory effect, the memory alloy pipe joint is subjected to thermal shrinkage, returns to the preceding state of hole enlargement; Because the internal diameter of pipe joint before the hole enlargement is littler than the external diameter of connected tube, produces big magnitude of interference and cooperate again, joint is fastened on the connected tube, realize connecting.
The utility model has the advantages that:
1. the utility model is easy to operate, the join strength height, and good airproof performance, corrosion-resistant, it is little to take up space.
2. the utility model is applicable to the connection between the xenogenesis tubing.
3. the utility model can cooperate with the connected tube of identical or different external diameter, realizes pipeline reducing diameter.

Embodiment
Embodiment 1
Shown in Fig. 1～2, pipe joint body 1 adopts the TiNiNb alloy to make, pipe joint body 1 is the memory alloy pipe joint with four interior convex ridges 11, convex ridge 11 is shaped as trapezoidal, connected tube is Stainless Steel Tube 3 and titanium alloy tube 2, connect back water pressure resistance 20MPa, do not leak, not lax in-50～300 ℃ of scopes.
Embodiment 2
As shown in Figure 3, two of elbow 4 leads to and is connected by pipe joint body 1 respectively with connected tube 5, and the break-in by elbow realization pipeline if the internal diameter difference of pipe joint body 1 can cooperate with the connected tube 5 of various outer diameter, can realize pipeline reducing diameter.If elbow becomes a threeway, can realize that just threeway connects.
As shown in Figure 4, be connected with aluminum pipe 6, Stainless Steel Tube 3, realize the connection of two kinds of pipelines that the foreign material performance difference is big by pipe joint body 1.
Embodiment 4
Difference from Example 1 is: as shown in Figure 5, convex ridge 11 is shaped as sharp-tooth shaped.
Difference from Example 1 is: as shown in Figure 6, convex ridge 11 is shaped as square.
Embodiment 6
Difference from Example 1 is: as shown in Figure 7, convex ridge 11 is shaped as circular arc.
