Embodiment 1
[0022] The low temperature resistant rubber hose assembly of the present invention is realized in this way, consisting of connecting pipe (1), annular groove (2), fastening screw sleeve (3), bowl-shaped groove (4), fixed pipe (5), inner liner pipe ( 6), hexagonal plate (7), pagoda connector (8), outer sealing sleeve (9), steel sheet (10), sealing packing ring (11), sealing head (12), sealing backing plate (13) and The support tube (14) is composed of one end of the support tube (14) connected to one end of the fixed tube (5) and communicated with each other. The outer wall of the support tube (14) is threaded, and the outer diameter of the support tube (14) is less than The outer diameter of the fixed tube (5), the inner diameter of the support tube (14) is smaller than the inner diameter of the fixed tube (5), the steel sheet (10) is placed on the end surface of the support tube (14), and is located in the fixed tube (5), the The steel sheet (10) is a multi-layer structure wi...
Embodiment 2
[0025] The difference between this embodiment and Embodiment 1 is: the sealing packing ring (11) is a single-layer conical ring, and there are multiple sealing rings on the outside, and there are multiple separation rings on the outside of the outer sealing sleeve (9). , and the outer side of the separation ring fits the inner wall of the fixed pipe (5); when in use, multiple sealing rings fit the wall of the bowl-shaped groove (4) respectively, and then perform multi-layer sealing, and the connecting pipe (1) and the support The sealing effect of the connection position of the pipe (14) is better, and the multiple partition rings on the outside of the outer sealing ring are respectively attached to the inner wall of the fixed pipe (5), and then multiple seals between the inner liner pipe (6) and the fixed pipe (5) are carried out. Layer sealing, better sealing effect;
[0026]The steel sheet (10) is a multi-layer structure with at least 3 layers, the thickness of the steel sh...
