Abstract
The utility model discloses a kind of high-pressure anti-wear metallic hose, comprise flexible metal connecting tube and the connecting head being arranged on metal connecting tube two ends, described connecting head is made up of plain joint and kink nut, plays connection function, described flexible metal connecting tube comprises oven wire mesh blanket, wavy metal tube layer and wearing layer, described oven wire mesh blanket is wrapped in wavy metal tube layer outer wall, described wearing layer is spring protecting sleeve, wearing layer can be placed in inside wavy metal tube layer or outside oven wire mesh blanket, the utility model is by reducing the pitch of waves of metal bellows, improve its pliability, oven wire mesh blanket, compression resistance can be improved, wearing layer plays a protective role, avoid solid particulate matter to the wear-out failure of pipe fitting inner wall or outer wall, thus improve the working life of connecting tube, indirectly reduce maintenance cost and cost of production.
Description
Technical field
The utility model relates to and a kind ofly has composite metal flexible pipe that is high pressure resistant, antiwear characteristic.
Background technique
Metallic hose is installed in equipment transporting system as a kind of flexible pressure-resistant pipe fitting, in order to compensate the mutual displacement of pipeline or machine, equipment connection end, absorbing vibrational energy, the effect such as vibration damping, noise reduction can be played, have flexible, quality is light, corrosion-resistant, the multinomial feature such as antifatigue, high-low temperature resistant.
But in the field that some are comparatively special, as the coal injection system of ironmaking, steel-making refining furnace, aluminium oxide, chemical industry, electric power, metallurgy and other dredge the occasion of solid, liquid material, require higher to the suppleness of metallic hose, anti-high pressure and antiwear characteristic, common metallic hose can not reach requirement, thus causing connecting tube short for working life, maintenance cost is high, and the breakage of metallic hose also may cause accident to occur.
Summary of the invention
The purpose of this utility model is to provide a kind of high-pressure anti-wear metallic hose, solves that metallic hose suppleness in prior art is poor, problem that resistance to compression and wear-resisting property can not reach special industry requirement.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-pressure anti-wear metallic hose, comprise flexible metal connecting tube and the connecting head being arranged on metal connecting tube two ends, described connecting head is made up of plain joint and kink nut, plays connection function; Described flexible metal connecting tube comprises oven wire mesh blanket, wavy metal tube layer and wearing layer, described oven wire mesh blanket is wrapped in wavy metal tube layer outer wall, oven wire mesh blanket is all fixedly connected with connecting head by welding manner with wavy metal tube layer, and by collar banding, described wearing layer is spring protecting sleeve.
Described wearing layer, according to applied environment, can be placed in inside wavy metal tube layer or outside oven wire mesh blanket, also or to be simultaneously arranged at inside wavy metal tube layer and outside oven wire mesh blanket.
Described connecting head also can be made up of flange.
As preferably, the pitch of waves and the outside diameter of bel ratio of described wavy metal tube layer are less than 15%.
As preferably, described oven wire mesh blanket is one or more layers.
The beneficial effects of the utility model are: the utility model, by reducing the pitch of waves of metal bellows, can effectively improve its pliability; And at wavy metal tube layer periphery one or more layers oven wire mesh blanket of parcel, effectively compression resistance can be improved; Inside wavy metal tube layer or oven wire mesh blanket arranged outside wearing layer, can play a protective role, avoid solid particulate matter to the wear-out failure of pipe fitting inner wall or outer wall.Experiment proves, in body, swiftly flowing particle reduces the wearing and tearing of inboard wall of tube body, thus improves the working life of connecting tube, indirectly reduces maintenance cost and cost of production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-kink nut; 2-plain joint; 3-wavy metal tube layer; 4-oven wire mesh blanket; 5-collar; 6-wearing layer.
Embodiment
High-pressure anti-wear metallic hose as shown in Figure 1, comprise flexible metal connecting tube and the connecting head being arranged on metal connecting tube two ends, described connecting head is made up of plain joint 1 and kink nut 2, plays connection function; Described flexible metal connecting tube comprises oven wire mesh blanket 4, wavy metal tube layer 3 and wearing layer 6, described oven wire mesh blanket 4 is wrapped in wavy metal tube layer 3 outer wall, oven wire mesh blanket 4 is all fixedly connected with connecting head by welding manner with wavy metal tube layer 3, and by the collar 5 banding, described wearing layer 6 is spring protecting sleeve, and the pitch of spring protecting sleeve equals the diameter of spring thread, and namely spring protecting sleeve is when without distortion, gapless between spring thread, avoids the intrusion of particulate matter.
The pitch of waves and the outside diameter of bel ratio of described wavy metal tube layer 3 are less than 15%.
Described oven wire mesh blanket 4 is one or more layers.
Described wearing layer 6, according to applied environment, can be placed in inside wavy metal tube layer 3 or outside oven wire mesh blanket 4, also or to be simultaneously arranged at inside wavy metal tube layer 3 and outside oven wire mesh blanket 4.Be placed in inside wavy metal tube layer 3, use when being applicable to have particulate matter to circulate in body, avoid particulate matter attrition tube inwall; Be placed in outside oven wire mesh blanket 4, be applicable to the situation that body external environment condition is more severe, avoid the impact wreckage to body outside such as external dust, other particulate matters.
Described connecting head, according to the size of hose diameter, can be made up of flange.
By reducing the pitch of waves of metal bellows, can effectively improve its pliability; And at wavy metal tube layer periphery one or more layers oven wire mesh blanket 4 of parcel, effectively compression resistance can be improved; Inside wavy metal tube layer 3 or oven wire mesh blanket 4 arranged outside wearing layer 6, can play a protective role, avoid solid particulate matter to the wear-out failure of pipe fitting inner wall or outer wall.
