The spring hose can meet the application requirements of large hardness, strong tensile strength and the like. The spring hose can be used as the inner layer of the driving corrugated hose, and can ensure the elasticity, compactness, tensile strength and long term non-deformation of the driving corrugated hose.
Description
Technical field
The utility model relates to a kind of spring hose, and is especially a kind of as the spring hose that drives the corrugated hose internal layer.
Background technique
Nuclear power technology all is that the U.S. and France are in monopoly position for a long time, and the nuclear power technology of China is limited by them for a long time.At present, China's nuclear power technology Gonna breakthrough present situation realizes production domesticization, and the research of high strength arc attitude bent axle spring hose is one of emphasis of nuclear industry correlation technique research and development.Nuclear power station reactor core neutron fluence rate measuring system, as with the moving miniature fission chamber as prober, driving corrugated hose is the important accessory of prober, because lean on it under high radiation, high temperature (350 ℃) environmental conditions, reactor core is accurately sent into and extracted out to prober, to reach the each point neutron fluence rate of measuring reactor.Driving the corrugated hose endothecium structure is to guarantee to drive elasticity, tightness, the pull resistance of corrugated hose and the important step of the shape that remains unchanged for a long period of time, therefore, the material of driving corrugated hose, heat treatment, hardness, intensity, geometrical shape, technology etc. all have higher requirement.Above-mentioned driving corrugated hose of the prior art is formed by three layers: internal layer is the snail flexible pipe, and the flexible pipe outside is by 20 steel wire parcels, and outermost surface is the spiral layers that is made of spiral wire.Solid screw axis or snail flexible pipe that present prior art provides all can not solve the pliability of survey meter with the driving corrugated hose.
The utility model overcomes the above defective of prior art, and a kind of spring hose is provided, and can solve solid screw axis or the not good problem of snail flexible pipe pliability.
Summary of the invention
The purpose of this utility model is to provide a kind of spring hose, solves solid screw axis or the not good problem of snail flexible pipe pliability.
The purpose of this utility model is achieved through the following technical solutions:
It is hollow hoses that the utility model provides a kind of spring hose, and its tube wall is formed by flat band helically coiling, and the cross section of flat band is the U type.Wherein, flat band is to the medial axis of spring hose indent, and the indent degree of depth is 0.16 ~ 3.0mm.The material of the flat band of U type is the XC-70 carbon steel, and width is 0.5 ~ 10.0mm, and thickness is 0.1 ~ 0.8mm, and hardness is 400 ~ 450HV.The coiling in the shape of a spiral of flat band, its coiling angle are 10 ° ~ 60 °.The internal diameter of spring hose is 1.0 ~ 5.0mm, and external diameter is 1.6 ~ 10.0mm, and pitch is 1.0 ~ 9.0mm.
The utility model spring hose can be used as the internal layer that drives corrugated hose, can guarantee to drive elasticity, tightness, the pull resistance of corrugated hose and the shape that remains unchanged for a long period of time.
The U type structure of the flat band of the utility model spring hose has played powerful supporting effect for each transversal plane of steel band, stressed when flexible pipe is subjected to brute force on three of the U type force bearing points of naming a person for a particular job is distributed on the adjacent spiral steel band and transmits successively, weakened the gathering of the power of steel band force bearing point, reduced the fatigue of the single force bearing point of steel band and hindered, for the prototype of recovering steel band has played great help.U type arc between pitch is delivered to next pitch with stressed under rapid just as stressed back cushion good between pitch, avoided the stressed impaired bending of single pitch, while pushing for noncentral force, the U type structure of spring hose passes to adjacent pitch successively with power, after having avoided the single pitch of flat strip flexible pipe stressed, unbalance stress between stressed each pitch causes the internal diameter of each pitch and the variation of external diameter not to wait, and has also avoided inlaying between the spring pitch.Anti-high-strength impact during for remote-controlled operation and flexible and the recovery excellent function arranged.
The utility model spring hose has good lateral stressed stability, it is subjected to the force intensity will be above the steel band flexible pipe of its thickness material more than two to three times, the slimming of while material and intensity turn to the interior external diameter of tubule footpath U-shaped steel band flexible pipe and the control of pitch provides basic guarantee, be included under the situation of stressed bending, guaranteed constancy between the big or small and adjacent pitch of interior external diameter.

Embodiment
Further elaborate the present invention below in conjunction with drawings and Examples.Following examples are not limitation of the present invention.Under the spirit and scope that do not deviate from inventive concept, variation and advantage that those skilled in the art can expect all are included among the present invention.
Be illustrated in figure 1 as the utility model spring hose 1, its tube wall is formed by flat band 2 helically coilings, as shown in Figure 2, the cross section of flat band 2 is the U type, and used material is the XC-70 carbon steel, and the width a of flat band 2 is 1.2mm, thickness b is 0.2mm, and hardness is 410HV.Flat band 2 is to the medial axis of spring hose indent, and indent degree of depth c is 0.16mm, and the degree of depth can produce the face contact phenomena that is similar to existing flat rubber belting spring hose inadequately, and the degree of depth is crossed can influence outside diameter d, D in the flexible pipe deeply.Flat band 2 obtains spring hose 1 along the central axis coiling, and the coiling angle [alpha] is 15 °.
In the utility model, the width a of flat band 2 is 0.5 ~ 10.0mm, and thickness b is 0.1 ~ 0.8mm, and hardness is 400 ~ 450HV.Indent degree of depth c is 0.2 ~ 3.0mm, and the coiling angle [alpha] is 10 ° ~ 60 °.
In the utility model, locate the size that graphics is measured the spring hose 1 of shaping according to projection, inner diameter d is 2.0mm, and outer diameter D is 2.6mm, and the pitch L of spring hose 1 is 1.5mm.Its hardness, tensile strength satisfy application demand.
In the utility model, the inner diameter d of spring hose 1 is 1.0 ~ 5.0 mm, and outer diameter D is 1.6 ~ 10.0mm, and pitch L is 1.0 ~ 9.0mm.
The processing technology and the heat treatment process of the flat band of U type in the utility model are the requirements in strict accordance with normal operation that drives the detection operations instrument under the environment of anti-nuclear radiation and high nuclear heat and data transmission.
The preparation of the utility model spring hose is by cutting die the flat band straight line of U type to be sent into fraising, with three reamer is constantly revised, and makes it to reach the Reference diameter and the pitch of spring hose.In order to eliminate the heat that produces in the process of rolling, adopt oiling agent to be lubricated and cooling.
The utility model is sent it into Take up unit after determining the pitch and inside/outside diameter size of spring hose, with the spring hose that is shaped on rotating disk.The rotational speed regulation of rotating disk is become speed synchronization with spiral forming, with the spring hose length that guarantees to produce greater than 1000 meters.The length of spring hose can be chosen according to actual demand, cleans, detects, packs.
