Abstract
The invention discloses a metal bellows. Epoxy anti-corrosion paint is applied on the inner wall of an inner layer, is strong in bonding force, and can be tightly combined with the inner wall, so that corrosion of the inner wall can be prevented, and the service life of a hose can be prolonged; the interspace of the inner layer and an outer layer is filled with glass wool, so that the temperature of the metal bellows can be maintained; the outer layer is coated with antifreezing paint, so that the condition that the metal bellows is subjected to frost cracking can be prevented; the thickness of the outer layer is 6 mm, and is the thinnest thickness for protecting the inner layer from being damaged, and the cost can be saved. The metal bellows has the advantages of being good in heat preservation effect and long in service life, and has wide market prospects.
Description
Technical field
The present invention relates to the bellows of conveying gas, particularly a kind of metal bellows.
Background technique
High altitude localities due to atmospheric pressure low, rarefaction of air, content of oxygen in air is low, thus easily causes anoxic and causes altitude sickness.In order to ensure the life and health of passenger and attendant, running on the traffic tool such as the train of high altitude localities and being all equipped with oxygen system, in extremely frigid zones or the large area of day and night temperature, pipe easily breaks, and especially it needs good antiseptic property.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of metal bellows, to solve the above-mentioned multinomial defect caused in prior art.For achieving the above object, the invention provides following technological scheme: a kind of metal bellows comprises bellows body and is welded on the interface at two ends, described bellows body is semicircle corrugated, described bellows body divides internal layer and skin, described internal layer is positioned at outer the inside, described internal layer and outer interlayer have gap, described outer outside arranges metal net cover, described metal net cover adopts Stainless Steel Band weaving, the diameter of described interface is greater than the diameter of metal bellows, described interface is stainless steel, and smooth surface.
Preferably, described internal layer inwall scribbles epoxy anticorrosive paint, and described epoxy anticorrosive paint bonding force is strong, closely ties with inwall.
Preferably, glass wool is filled with in the space in the middle of described internal layer and skin.
Preferably, described skin is covered with antifreezing dope.
Preferably, described outer field thickness is 6 millimeters.
The beneficial effect of above technological scheme is adopted to be: to the invention discloses a kind of metal bellows, described internal layer inwall scribbles epoxy anticorrosive paint, described epoxy anticorrosive paint bonding force is strong, combine closely with inwall, the corrosion of inwall can be prevented, extend the working life of flexible pipe, glass wool is filled with in described internal layer and outer field space, the temperature in metal bellows can be maintained, described skin is covered with antifreezing dope, metal bellows can be prevented by bursting by freezing, described outer field thickness is 6 millimeters, this thickness is the most minimal thickness be not damaged at protection internal layer, cost can be saved, this metal bellows has high insulating effect, the advantage of long service life, there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the structural representation faced of this practical a kind of metal bellows;
Fig. 2 is a kind of structural representation of metal bellows.
Wherein, 1-metal bellows, 2-interface, 3-internal layer, 4-skin, 5-metal net cover, 6-Stainless Steel Band, 7-epoxy anticorrosive paint, 8-glass wool, 9-antifreezing dope.
Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the specific embodiment of the present invention: a kind of metal bellows, it is characterized in that, comprise bellows body 1 and the interface 2 being welded on two ends, described bellows body 1 is semicircle corrugated, described bellows body 1 point of internal layer 3 and outer 4, described internal layer 3 is positioned at inside outer 4, gap is had between described internal layer 3 and outer 4, outside described outer 4, metal net cover 5 is set, described metal net cover 5 adopts Stainless Steel Band 6 to weave, the diameter of described interface 2 is greater than the diameter of bellows body 1, and described interface 2 is stainless steel, and smooth surface.
In addition shown in Fig. 2, described internal layer 3 inwall scribbles epoxy anticorrosive paint 7, and described epoxy anticorrosive paint 7 bonding force is strong, combines closely with inwall, and be filled with glass wool 8 in the space in the middle of described internal layer 3 and outer 4, described skin is covered with antifreezing dope 9.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
