Abstract
Provided is a new refractory heat insulation soft pipe the pipe wall of which comprises a rubber layer, a fireproof layer, a woven net layer and a casing from the center to the surface in sequence. The utility model is characterized in that the casing is composed of a steel wire mesh and a high strength wear resistance protection layer which is coated at the outer side of the casing. The protection layer is made of high strength plastic and the inner side thereof is immersed into the gap of the steel wire mesh in a holt melt way. The casing of the utility model is altered into a fused integral structure from the original separated structure to make the metal woven net layer firmly connected with the casing layer thus to prevent the dropping of the casing and the outer oil from immersing into the metal wire mesh to corrode. The utility model with a good flexibility and a long working life avoids the slide friction between the two layers and the smooth outer surface strengthens the wear resistance performance thereof.
Description
Technical field
The utility model relates to a kind of liquid conveying hose, is mainly used in the conveying of high-temp liquid in the industries such as petrochemical industry and metallurgy.
Background technique
General its tube wall of existing this flexible pipe all has multilayer material to be composited, and has higher Fire insulation.I am to disclose a kind of refractory heat-insulating hose in 92104811.4 in the patent No., and its tube wall is made up of the different materials of 4-12 layer.Secondly skin is gauze fabric, and skin is a restrictive coating, and general jacket layer is to be enclosed within gauze fabric layer outer bellows or rubber sleeve, and its shortcoming is an insufficient strength, poor sealing, two-layer between in conjunction with insecure, easily come off, wear resistance is also bad.
Summary of the invention
The purpose of this utility model just provides a kind of novel refractory heat-insulating hose, to solve the problem that overcoat is insecure, sealing is poor, wear resistance is bad.
The technical solution of the utility model is: a kind of novel refractory heat-insulating hose, its tube wall comprise rubber layer, fire protection layer, web layer and overcoat from the inside to the outside successively, and described overcoat is made up of one deck high-strength abrasion-proof protective layer of steel wire and outside coating thereof.
Described protective layer is made by the highstrenghtpiston, and its inboard hot melt immerses the slit of described steel wire.
Overcoat of the present utility model changes the structure of original mutual disengaging into the structure of mutual fusion one, make the gauze fabric layer with jacket layer securely in conjunction with and, avoided coming off of jacket layer, also prevented to make the wire gaze corrosion in the oil outer water dipping tube, flexible good, life-span is long, has also prevented the skimming wear between two-layer, and smooth outer surface has strengthened its wear resistance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is made of 4-12 layer from the inside to the outside, and inboard each layer 3 is from the inside to the outside successively: rubber layer, steel wire floor, rubber layer, fire resistant coating, thermal-protective coating, zinc-plated steel mesh, fireproof paint layer, fire-retardant winding layer, web layer, polyethylene coating, fireproof paint layer.The jacket layer of outermost is made up of one deck high-strength abrasion-proof protective layer 1 of steel wire 2 and outside coating thereof.
Described protective layer 1 is made by high-intensity plastics, and its inboard hot melt immerses the slit of described steel wire 2.
Claims (2)
1, a kind of novel refractory heat-insulating hose, its tube wall comprises rubber layer, fire protection layer, web layer and overcoat from the inside to the outside successively, it is characterized in that: described overcoat is made up of one deck high-strength abrasion-proof protective layer of steel wire and outside coating thereof.
2, novel refractory heat-insulating hose according to claim 1, it is characterized in that: described protective layer is made by the highstrenghtpiston, and its inboard hot melt immerses the slit of described steel wire.
