Title
(EN) BRAIDED TUBE ASSEMBLY
(FR) ENSEMBLE TUBE TRESSÉ
(ZH) 一种编织管总成
Abstract
(EN) Disclosed is a braided tube assembly. The braided tube assembly comprises a braided tube body (1), a left joint (2) and a right joint (6). The braided tube body comprises an inner tube (1a), the left joint comprises a left connecting rod (2a) inserted into the inner tube, the right joint comprises a right connecting rod (6a) inserted into the inner tube, an outer side face of the left connecting rod and an outer side face of the right connecting rod are each provided with a protruding convex ring (12), an inner side face of the inner tube is provided with a recess (1a2) corresponding to the convex ring, the convex ring is embedded into the corresponding recess, an outer side face of the convex ring is provided with an annular fixing groove (12a), a sealing ring (13) made of EPDM rubber is fixed in the fixing groove, and an outer side face of the sealing ring abuts against the bottom face of the recess to form a seal. The connection of the left joint and the inner tube and the connection of the right joint and the inner tube in the braided tube assembly are not prone to leaking liquid in a low-temperature environment.
(FR) La présente invention concerne un ensemble tube tressé. L'ensemble tube tressé comprend un corps de tube tressé (1), un joint gauche (2) et un joint droit (6). Le corps de tube tressé comprend un tube interne (1a), le joint gauche comprend une tige de raccordement gauche (2a) insérée dans le tube interne, le joint droit comprenant une tige de raccordement droite (6a) insérée dans le tube interne, une face latérale externe de la tige de raccordement gauche et une face latérale externe de la tige de raccordement droite sont chacune pourvues d'une bague convexe saillante (12), une face latérale intérieure du tube interne est pourvue d'un évidement (1a2) correspondant à la bague convexe, la bague convexe est incorporée dans l'évidement correspondant, une face latérale extérieure de la bague convexe est pourvue d'une rainure de fixation annulaire (12a), une bague d'étanchéité (13) en caoutchouc EPDM est fixée dans la rainure de fixation, et une face latérale extérieure de la bague d'étanchéité vient en butée contre la face inférieure de l'évidement pour former un joint d'étanchéité. Le raccordement du joint gauche et du tube interne et le raccordement du joint droit et du tube interne dans l'ensemble tube tressé ne sont pas sujets à une fuite de liquide dans un environnement à basse température.
(ZH) 一种编织管总成,包括编织管本体(1)、左接头(2)和右接头(6),编织管本体包括内管(1a),左接头包括插入到内管中的左连接杆(2a),右接头包括插入到内管中的右连接杆(6a),左连接杆的外侧面上和右连接杆的外侧面上均设置有凸出的凸环(12),内管的内侧面上具有与凸环对应设置的凹槽(1a2),凸环嵌入到对应的凹槽内,凸环的外侧面上开设有呈环形的固定槽(12a),固定槽内固定有由EPDM橡胶制成的密封圈(13),密封圈的外侧面抵靠在凹槽的底面上并形成密封。该编织管总成中左接头与内管的连接处以及右接头与内管的连接处在低温环境中均不易发生液体的泄漏。
