Abstract

A CNG conveying hose for a gas filling / gas discharge pillar of a gas station belongs to the technical field of conveying hoses used for CNG (compressed natural gas) filling equipment and specifically relates to an improvement of a CNG conveying hose structure. The invention provides the hose used for conveying the CNG, wherein the hose has a long service life, good hose body pulse-resistant performance, high resistance to leakage, high resistance to pressure, resistance to static electricity, resistance to aging and resistance to wearing. The hose provided by the invention comprises a medium-resistant conducting layer and is characterized in that the medium-resistant conducting layer is coated by a medium-resistant anti-leakage strong layer, an adhesive layer, a knitted strengthening layer, a rapid conducting layer and an outer protective layer successively from inside to outside; and an end part of the rapid conducting layer is connected to an end part of the medium-resistant conducting layer.

Description

technical field [0001] The invention belongs to the technical field of conveying hoses for CNG (compressed natural gas) gas filling equipment, in particular to an improvement in the structure of CNG conveying hoses. Background technique [0002] Due to the rise in oil prices, the use of compressed natural gas is increasing, and there are more and more natural gas filling stations in various regions, and the use of compressed natural gas pipes is also increasing. [0003] Due to the high pressure (normal working pressure is 35Mpa) and strong permeability of the compressed natural gas pipe, the compressed natural gas pipe has the problem of short service life (not more than 3 months), and the existing natural gas pipe has bulging on the surface Defects such as peeling or peeling of the protective layer are more likely to cause air leakage accidents. Moreover, due to the short service life and frequent replacement, the cost of use is greatly increased. [0004] The pressure o...
