Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to joints used to connect pipes to each other, and particularly relates to joints with bending, rotation, suppression of different core load functions, and multiple uses. Connector for heat-resistant piping with suppressed eccentricity (displacement absorption) function. [Known technology] When the conventional pipe joint is the c-type joint 10 shown in FIG. 4 'weld the C-shaped wire ring 1 2' at a predetermined position on the pipe end of the two pipes 1 1 and insert the rubber ring 13 into the two pipe ends. It is formed by covering the casing 14, and the C-ring is set on the circumference of the groove portion of the casing 14, and the seal is fixed by bolts 15 to make the rubber ring 13 realize its function. The sealing principle (automatic seal) of the C-shaped joint 10 series and the U-shaped full circle is basic, so that the two pipes 11 connected can be stably moved within the functional range of the joint to obtain an air-tight effect. As shown in Figure 5, the design width is larger than the width of the housing for the hooking width, so that the clearance (E-size) can absorb expansion, contraction, flexure (displacement absorption), and rotating joints. This is explained in detail below. (1) Expansion (refer to Figure 6 (a)). The clearance is the maximum E dimension of the whole 'so that the clearance at the end of the tube is 0 and the tube can be contracted when it is equal to the E dimension. When the maximum E size is set as the clearance at the end of the tube, it can absorb the extension of the tube with the same E size. Based on the expansion and contraction of the general absorption tube, the size E is determined from the temperature difference during use and the temperature difference between the piping and the extension of the piping tube. The paper size of the absorber is in accordance with China National Standard (CNS) A4 (210 X 297 (Mm) (Please read the notes on the back before filling out this page) Binding ---- Order --------- line, printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 461945 A7 B7 V. Description of Invention (2) Shrink. The amount of expansion and contraction E of the tube is obtained by the following formula. < .E = L (pipe length) Xd (linear expansion coefficient) X t (temperature difference) The linear expansion coefficient of iron is 1.2 2 X 1 0 5 (2) Bend (see figure 6 (b)) To one side 0. When E on one side is the clearance at the end of the pipe, the pipe system is bent, and its amount is obtained by the trigonometric function of the outer diameter of the pipe (0, D) and the size of E. sin0 = E / (〇, D) (3) Eccentricity (see Figure 6 (c)) Eccentricity cannot be absorbed by one joint. It is necessary to use the two joints of the 6th (c) break, which can bend the joints and absorb the eccentricity of the pipe length. Eccentricity 5 = L-sin (9 (4) rotation (see figure 6 (d)) can only be rotated by the rubber ring contacting the tube. The high tightness of the rubber ring allows the tube to rotate even 3 6 0 ° Without any leakage, the use of elbow pipe can be used as a pipe for relative interlayer displacement and uneven sinking absorption. The above is the basic structure and function of this joint.

Description of the Invention (3) [Problems to be Solved by the Invention] This type of pipe joint is a flexible plumbing method that is widely used in various industries. However, depending on the purpose of the piping and piping conditions, the above functions can be reversed. Occasions that lead to instability. It refers to heat-resistant piping such as hot water, warm water, cold and warm water pipes of Jianfeng equipment piping. The joints have bending and multiple eccentric suction. The collection function is to allow the rubber to undergo displacement. Plastic changes, deterioration, etc. Leakage. Various stresses and loads are generated on the piping when piping, after piping, and during operation. Even as described above, the rubber ring can still maintain the shape, elasticity, and size of the sealable state according to the appointed conditions. Therefore, the present invention The problem to be solved is to provide a heat-resistant piping joint that does not require more than necessary load on the rubber ring, and can maintain the sealing performance for a long period of time. [Solution to the problem] To solve the above problem, the pipe end has two pipe ends surrounding it. The casing and the heat-resistant piping joint made of the sealing rubber ring provided on the inside of the casing are provided with flange portions around the outer edge portion of the casing.
