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...

Abstract

The invention provides a low temperature resisting rubber pipe assembly and discloses a low temperature resisting oil pipe connector formed in a manner that high polymer materials serve as a filler, deformation filling is carried out through threaded connection and extrusion to form a seal and a liner pipe is cooperated to carry out supporting. The low temperature resisting rubber pipe assembly ischaracterized in that one end of a supporting pipe is connected with one end of a fixing pipe in a communicating manner, the outer side wall of the supporting pipe is provided with a thread, the external diameter of the supporting pipe is smaller than that of the fixing pipe, and the internal diameter of the supporting pipe is smaller than that of the fixing pipe; and a steel disc is arranged onthe end face of one end of the supporting pipe and located in the fixing pipe, the liner pipe is arranged in the fixing pipe, one end of the liner pipe is connected with the steel disc, the liner pipeis sleeved with an outer sealing sleeve which is made of a desulfurized rubber material, the outer sealing sleeve and the inner wall of the fixing pipe are spaced, the two ends of the outer sealing sleeve are bent in the reverse directions and make contact with the inner wall of the fixing pipe, the other end of the fixing pipe is of a tapered structure, and one end of a tower connector is arranged in the other end of the fixing pipe.

Description

technical field [0001] The invention relates to a low-temperature-resistant rubber hose assembly, which relates to a connector used for connecting and sealing oil pipes of mechanical equipment in a low-temperature environment, and belongs to the field of mechanical accessories. In particular, it relates to a low-temperature-resistant oil pipe joint that utilizes polymer materials as fillers, is deformed and filled to form a seal through screw connection and extrusion, and is supported by an inner lining pipe. Background technique [0002] At present, when mechanical equipment is working, it needs to use hydraulic pressure as a supporting mechanism, and it needs to transport hydraulic oil through external oil pipelines, especially some construction machinery, such as excavators, truck-mounted cranes, etc., and due to the harsh operating environment of the above-mentioned construction machinery, Construction work is often carried out outdoors, and some work in extremely low-te...
