Description

The device of processing metal multiple tube

Technical field

The utility model relates to a kind of device of processing metal multiple tube, relates to specifically by the device of metal pipe internal wall lining with the processing metal multiple tube.

Background technology

Be widely used in the metallic conduit of carrying liquid or gas, be used to be subjected to the restriction of cost, the general ordinary carbon steel material that adopts, but in use, the problem that has seriously corroded, contain impurity in feasible on the one hand liquid that is transferred in corrosion back or gas, influence is transferred quality liquid or gas, can reduce the service life of metallic conduit on the other hand.In order to improve the service life of metallic conduit, spraying one deck protective paint in metallic conduit comes off easily yet coat with lacquer protective layer usually; No matter in addition, also have the inner surface at metallic conduit to carry out copper facing, nickel plating, be to adopt to spray paint or electric plating method, for elongated pipeline, all be difficult on the technology realize, and the cost of electro-coppering and electronickelling is very high; Another is a vacuum metal film plating, and the shortcoming of this method is: the equipment price costliness of vacuum coating, also only can plate very little parts, and can not plate big parts, more can not be applied in the long pipeline.

In recent years, having produced a kind of new technical scheme, adopted composite bimetal pipe, promptly is that the inner surface at common metal tube adds the corrosion resistant metal tube of last layer to improve the corrosion resistance of common metal pipe, does not need complex apparatus simultaneously.The CN2431063Y utility model patent promptly discloses a kind of metallic conduit detonation Lining device, this device comprises: can be close to the lining of inner wall of metal tube, the upper cover that is arranged on the upper end and the low head of lower end, be arranged on high-energy fuel and fuel fixed mechanism in the lining, and the liquid medium that transmits power, be arranged on the coupling sleeve that is connected with primacord that is connected with high-energy fuel of going up of upper cover.The high temperature, the gases at high pressure that are produced when high-energy fuel is ignited through the liquid medium transmission, radially outward expand lining, are close on the metal pipe internal wall.Yet this technical scheme still has following problem: its complicated operation, need bushing pipe is sealed at both ends, and the adding liquid medium, can implement, and in implementation process, there is impurity in the inwall of common metal pipe, when igniting high-energy fuel, under high heat effect, impurity can produce vaporization, can produce bubble between the two-layer tube wall, lining can not be fitted with inner wall of metal tube in good condition.Therefore, in order to address the above problem, the utility model proposes a kind of device of easy to operate processing metal multiple tube simple in structure.

The content of utility model

The purpose of this utility model is to provide a kind of device of processing metal multiple tube, and it is simple in structure, and is easy to operate, can prevent the generation of bubble between the bimetal pipe.

To achieve these goals, the technical solution of the utility model is: a kind of device of processing metal multiple tube, one is loaded on the metal liner in the metal parent tube, it comprises: a primacord is located in the metal liner, be provided with the fixture that is used for fixing primacord at the two ends of metal liner, the two ends of primacord fixing with described fixture on, be coated with the high-energy fuel layer at described primacord, one end of described primacord passes the described fixture outside and is connected with detonator, and the other end of detonator is connected with to detonate uses electric wire.

The described primacord that high-energy fuel is housed is positioned at the center of metal liner.

Described high-energy fuel layer is high-energy solid gunpowder layer, explosive layer or other high-energy solid propellant layer.

The described fixture that is fixed in the two ends of metal liner is that disk is tabular or be cruciformity or be the long strip-board shape by metal liner end face center.

Owing to adopt technique scheme, cancel the parts such as upper and lower end socket in the CN2431063Y utility model patent, promptly do not needed internal lining pipe is made close cavity, and in the middle of neck bush, need not inject liquid medium, thereby make structure more simple, operate more convenient.

During use, only in air, both can ignite high-energy fuel, in the high-energy fuel blast, produce high temperature and high pressure gas; the metal lining of thin-walled is under the effect of the power that expands outwardly; utilize the ductility of metal; metal lining fully is fitted on the inner surface of metal-coating, both are closely as one.The utility model can also carry out the operation of above-mentioned blast in big pond, can make neck bush stressed more even like this, simultaneously, can play the effect of cooling to metal outer pipe, to avoid the generation of metal pipe internal surface impurity vaporization.

Description of drawings

Fig. 1 is the structural representation of the utility model one specific embodiment;

Fig. 2 is the utility model user mode figure.

The specific embodiment

Describe the utility model in detail below in conjunction with specific embodiment, referring to Fig. 1, the device of having showed a kind of processing metal multiple tube among the figure, one metal liner 2 is housed in metal parent tube 1, the light-wall pipe that metal liner 2 is made for stainless steel material, one primacord 4 is located in the metal liner 2, be provided with the fixture 3 that is used for fixing primacord at the two ends of metal liner 2, this fixture 3 is a cruciformity, the two ends of primacord 4 are fixed on the described fixture 3, and this primacord 4 is fixed on the center of metal liner, so that stressed even around explosion time metal inner lining pipe 2.Be coated with high-energy fuel layer 7 at described primacord 4, adopt solid gunpowder in the present embodiment, one end of described primacord 4 passes described fixture 3 outsides and is connected with detonator 6, and the effect of detonator 6 is to ignite gunpowder 7, and the other end of detonator 6 is connected with and detonates with electric wire 5.

What should illustrate is, described metal liner is not limited to stainless steel material, also can be other corrosion resistant metal material, and the fixture of primacord also is not limited to the cross shape, also can adopt other shapes; Its high-energy fuel that adopts is not limited to the high-energy solid gunpowder, also can be other fuel, for example high-energy solid or liquid propellant layer.

Referring to Fig. 2, stainless steel bushing pipe 2 is penetrated in the metal parent tube 1, the primacord 4 that will have high-energy solid gunpowder 7 penetrates in the stainless steel bushing pipe 2, the two ends of primacord are fixing with fixture 3, and make it to be in the center of stainless steel bushing pipe 2, so that when gunpowder explosion, the bushing pipe inwall is stressed evenly.Detonator 6 is connected in the end of the primacord 4 that the fixture outside stretches out, and detonator 6 connects and detonates with electric wire 5, and this device is positioned in the pond, ignites gunpowder by electric wire 5.During 7 detonations of high-energy solid gunpowder, the water of the gas of the HTHP that is produced in the pond passes to stainless steel lining 4, and stainless steel lining 4 radial forces outwards expand, and lining tightly are attached to the inwall of metallic conduit 1.Because whole metal parent tube and Lining device are all in the pond, it can reduce the temperature of metal parent tube, avoid the impurity of parent tube wall inwall to produce vaporization phenomenon under high temperature action, make to combine more closely between liner and the parent tube, the quality of metal composite pipe is improved.

The utility model can also not be placed in the pond to be ignited, and directly places air to ignite, and by the transmission medium of air as power, directly carries out lining, and its operation is more easy.

From the above, the device of processing metal multiple tube of the present utility model, more simple with existing Lining device structure compared, more convenient operation can improve the quality of metal composite pipe.
