SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a pipe joint in which a sanitary pipe is also connected without using a seal. The pipe joint for sanitary piping of the invention is characterized in that a short pipe _ at a side end opposite to a side connected to a surgical pipe is formed with a flange 〇 5; the flange portion - side is formed to protrude in the axial direction The cylindrical protrusion extends the inner circumference of the short pipe member and forms a circle surrounded by the entire circumference at the outer circumferential end of the dog outlet, and the 丨& 3 @ υ J surface is rounded a flange portion is formed on the opposite side shaft end of the other side of the pipe connecting the side of the surgical pipe, and a flange portion is formed on the side of the flange portion to allow the protrusion portion to cooperate with the gap The bottom surface of the large diameter portion is formed in the depth direction so that the inner diameter of the short s member is continuously reduced and pushed, wherein the short tube structure on the one side is in the large diameter of the short tube member embedded in the other side. The state shape #(elamp) holds the two flange portions so that the circle I 卩 is pressed against the push-out portion. With the above structure, it is formed by the 圆形 ▲ ▲ which is formed on the short portion of the short S member formed on the short S member.卩 contact, from the local scrape view /, ·! The arc is in contact with the plane, and the contact boat forms a continuous circular line contact, and at the same time enables the short pipe member to have no gap and the flange portion of the short pipe member to make contact. Further, the circular portion ink is attached to the push-out portion by the nip η , to be rounded. The gap between the 卩 and the pusher can be ^ ^ B + J paying for the obstacles. Therefore, the four-story can be used to connect the short pipe members to each other even without using a seal.

2014-6568-PF 001 之配管呈水密性連接β 此外’因一側短管構件穿Ψ s稱件之犬出部，可與另一側短管構件之大徑部間隙配合，因此，檑 u此，僅通過將該突出部嵌入大部，便能夠簡單調整短管構件之間 e傅1干4間位置。同時，於取下持構件後或安裝之前，亦可播办了通過上述嵌合使短管構件相互保持配合，因此能夠進一步提高管接頭之分離、組合等摔作性能。保上述衛生配管用管接頭中，可分別於上述各短管構件中與凸緣部鄰接之位置形成厚壁部。採用上述結構，因在與凸緣部鄰接之位置形成厚壁部’即使在與短管構件之凸緣部側相反側端部焊接配管，該焊接所產生之熱可於該厚壁部予以發散，從而能夠防止因焊接熱之傳導而使於凸緣部一側形成之圓形部或推拔部產生較大變形，以此可確保短管構件之間無間隙接觸狀態。上述衛生配管用管接頭中，可於上述一側短管構件或者上地另-側短管構件上所形成厚壁部之内圓周面上，形成向徑向内側突出之士m n士 ^之卡止邛，问時於從該卡止部向上述凸緣部-側偏離-定距離之位置上形成溝槽部。於該短管構件之内部，用於過滤流入短管構件内部之流體内所混入異物之過滤器’從上述凸緣部一側固定於上述卡止部，且與 a卡止^卜起夾住該m之環狀金屬件被嵌入該溝槽部。採用上述結構，利用於一側短管構件或另一側短管構所形成之厚壁’旎夠形成在薄壁部難以形成之溝槽The pipe of 2014-6568-PF 001 is watertightly connected. β In addition, the dog's outlet part of the short pipe member can be matched with the large diameter of the other short pipe member. Therefore, 檑u Therefore, by simply inserting the protruding portion into a large portion, it is possible to easily adjust the position between the short tube members and the e-four stems. At the same time, the short pipe members can be held together by the fitting after the removal of the member or before the mounting, so that the separation and combination of the pipe joints can be further improved. In the pipe joint for sanitary piping described above, a thick portion may be formed at a position adjacent to the flange portion of each of the short pipe members. According to the above configuration, since the thick portion is formed at a position adjacent to the flange portion, even if the pipe is welded to the end portion opposite to the flange portion side of the short pipe member, the heat generated by the welding can be diverged in the thick portion. Therefore, it is possible to prevent the circular portion or the push-out portion formed on the side of the flange portion from being largely deformed by the conduction of the welding heat, thereby ensuring a state in which there is no gap contact between the short tube members. In the pipe joint for sanitary piping, the inner circumferential surface of the thick-walled portion formed on the one side short pipe member or the upper-side short pipe member may form a card that protrudes radially inward. At the time of the stop, a groove portion is formed at a position deviated from the locking portion to the flange portion side by a predetermined distance. Inside the short pipe member, a filter for filtering foreign matter mixed in the fluid flowing into the inside of the short pipe member is fixed to the locking portion from the side of the flange portion, and is clamped with the a card. The annular metal piece of m is embedded in the groove portion. With the above structure, the thick wall formed by the one short pipe member or the other short pipe structure can be formed into a groove which is difficult to form in the thin portion.

The above effect can be obtained. The radius of the cross section of the circular cymbal Ma is 1 mm, and the degree of inclination of the push-out portion 24a is 45. When you get the best results. In addition, if the radius of the circular weir 14a is too large, the width of the contact line formed by the crimping of the circular weir 14a and the push-out portion 24 is increased by elastic deformation, so that the pressure drop 2014-6568-PF 10 1328661 is low, This results in poor sealing performance. On the other hand, if the circular portion is pinched too small, the push-out portion 24a is damaged by the circular portion 14a, and the debris formed after the damage enters the pipe. Further, if the degree of inclination of the push-out portion is too large or too small, it is difficult to ensure that the short pipe members 1 and 2 are brought into contact with each other in a state in which the two flanges 12 and 22 of the short pipe member (7) (3) are parallel to each other, thereby making it difficult to ensure Sealing. Further, since the large diameter portion 24 of the side short tube member 20 is gap-fitted by the protruding portion μ of the one short tube member 1〇, the short tube member 10 can be simply adjusted by simply inserting the protruding portion 14 into the large diameter portion 24. At the same time, after the removal of the clamping member 3Q or before the installation, the short tube members 10, 20 can be kept in cooperation with each other, so that the decomposition, assembly, etc. of the joints can be improved. performance. As shown in Fig. 2, the large-diameter portion 24 of the short pipe member 2 is not pushed out from the door material, but has a portion of the diameter between the open end and the push-out portion, and is in the portion The protruding portion of the short pipe member (7) can be moved at a slight interval. Therefore, it is possible to suppress the occurrence of 0 and the other short pipe members between the short side pipe members 2 of the side. With the short tube structure: Ι: set the mutual. The position of the weir 20 can be correctly kissed. The push-out portion 24a is not directly inscribed with the short tube member 2, but the push-out portion 24a is formed: all of them are inserted and the circle 24b is arranged. The part 'passes through the flat bottom surface 2 formed: as long as the short tube member 1〇, 2〇 is left between the right side and the right side, there is liquid retention, and there may be a detention place.
