Abstract
The utility model provides a new metal flexible pipe for the safety protection of an electric line of mechanical equipment and the conduction of liquid stream. The new metal flexible pipe is formed by galvanized steel strips which are wound together, the inner part of the metal flexible pipe is lined with a plastic lining layer while the metal flexible pipe is in winding processs, and the plastic lining layer is firmly bonded with the metal flexible pipe. The new metal flexible pipe can replace the existing knitted metal flexible pipes and other metal flexible pipes with single function. The utility model has the functions of water prevention, oil prevention, burning prevention and pressing resistance, which can conspicuously increase the safety protection property.
Description
The utility model relates to a kind of novel metal hose that is used for the electric wiring safety protection and the transporting of liquid stream of machinery.
At present,, all require to adopt safety prevention measure, just will adopt and to carry out flexible moulding, again the articles for use that can carry out safety protection to electric wiring and transfusion as the transporting of liquid such as the electric wiring of machinery and cooling liquid stream.Existing protective articles all is a metallic hose of tool simple function, and is non-watertight, not grease proofing as P3 type metallic hose, and its function singleness is for flexible moulding is used; Though SP3 type metallic hose energy waterproof, grease proofing can not be anti-scald, not withstand voltage; BSP3 type metallic hose can waterproof, grease proofing, anti-scald, but can only transporting limits the liquid stream of pressure, and complex structure, the manufacture cost height.Lack the metallic hose that gathers multi-function in integral whole in the practical application, promptly can waterproof, grease proofing, anti-scald, shield withstand voltage metallic hose that again can transporting certain pressure fluid.
The purpose of this utility model is to provide a kind of and moulds metallic hose in novel, and it gathers multi-function in integral whole, and waterproof, grease proofing, anti-scald, withstand voltage can significantly improve the performance of safety protection.
The purpose of this utility model can be achieved by the following drawings and embodiment.
Fig. 1 is the schematic representation of a kind of concrete structure of the utility model.
Form structure of the present utility model is identical with existing metallic hose, adopts Galvanized Steel Strip to roll into.This metallic hose 1 is distributed in metallic hose 1 inwall with plastics lining 2 when rolling, and adopts the technological method that adds hot extrusion, and plastics lining 2 and metallic hose 1 strong bonded are integral.The thickness of plastics lining 2 is 0.5-1.0mm, mainly chooses according to the nominal diameter of metallic hose 1.Recommend the plastic lining layer thickness as follows generally speaking: when the nominal diameter of metallic hose 1 was 8-20mm, the thickness of plastics lining 2 was 0.5mm; When nominal diameter was 25-51mm, thickness was 1.0mm.The raw material of plastics lining 2 is preferentially selected the soft polyvinyl chloride plastic of cable industry for use.
Basically have the close of common metal flexible pipe together now owing to mould the form structure and the manufacturing process of metallic hose in the utility model, the heat pressing process of plastic lining lining is simple, the professional and technical personnel is easy to grasp its manufacturing process, so the utility model is easy to implement.Particularly this product can satisfy flexible modeling requirement, can play the effect of safe and reliable protection and liquid stream transporting again.According to the requirement of usability,, just can realize waterproof, function such as grease proofing, anti-scald, withstand voltage as long as select the thickness of suitable plastic lining for use.Because it is simple in structure, manufacturing process is grasped easily again, and the yield rate height can obviously reduce the energy and consumption of raw materials, so can widen its using value and application area, is the desirable safety protection articles for use that replace flexible hose and other simple function metallic hose.
Claims (3)
1, a kind of by Galvanized Steel Strip roll in mould metallic hose, it is characterized in that at metallic hose inner wall even distribution plastics lining.
2, flexible pipe according to claim 1, the thickness that it is characterized in that the plastics lining is 0.5-1.0mm.
3, flexible pipe according to claim 1 is characterized in that the raw material of plastics lining is preferentially selected the soft polyvinyl chloride plastic of cable industry for use.
