Abstract
The utility model discloses an ungalvanized sealing tool for blank pipe inner wall and relates to an ungalvanized sealing tool for blank pipe inner wall. The tool comprises plugs (2), a nut (3) and adouble-end stud (4), wherein the plugs (2) are arranged at and tightly connected with two ends of a steel pipe (1), the double-end stud (4) is axially arranged at the central part of the plug (2), andthe nut (3) and double-end stud (4) are screw-connected to fix the plug (2). The tool has simple structure, convenient usage and no zinc plated on the long pipe inner wall when galvanization, saves cost, reduces energy consumption, reduces pollution, improves adhesive force of the lining copper pipe and roller coating plastic layer, and prolongs the service life of the pipe.
Description
Technical field:
The utility model relates to the not zinc-plated sealing tool of a kind of blank pipe inwall.
Background technology:
Be to improve the corrosion resistance nature of steel pipe, general steel pipe is carried out zinc-plated, galvanized steel pipe divides two kinds of pot galvanize and electro-galvanizings, the zinc-plated bed thickness of the steel pipe of pot galvanize, and the surface is not very smooth.It is very extensive that galvanized pipe uses, and it can be used for giving gas and heating installation, can used as water pipe, and can build booth etc., but the gas that in galvanizing process, is produced contaminate environment not only, and influence operator's health.Used for galvanized tube is when chemical field, and anticorrosion problem is difficult to solve, and cost height such as copper pipe, stainless steel tube.For the better protection inside pipe wall, can inner liner stainless steel pipe or copper pipe and roller coating plastic layer be set at the steel pipe inwall, but the zinc coating of inside pipe wall has reduced the sticking power of liner copper pipe and plastic layer, has influenced the work-ing life of galvanized pipe, has also increased cost.If before adhering to plastic layer, strike off the zinc layer of inside pipe wall, not only improved cost, also increased energy consumption.In order to make the steel pipe inwall not zinc-plated, with stopper with the sealed at both ends high temperature galvanizing flux of putting into again of steel pipe, but the pipe in the air expanded by heating, the accident of easily blasting.
The utility model content:
The purpose of this utility model provides the not zinc-plated sealing tool of a kind of blank pipe inwall, and it is simple in structure, and is easy to use, when zinc-plated, inside pipe wall can not plate zinc, saves cost, cuts down the consumption of energy, reduce and pollute, improve the sticking power of liner copper pipe and roller coating plastic layer, prolong the work-ing life of pipe.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of stopper 2, nut 3 and studs 4, stopper 2 is arranged on steel pipe 1 two ends and closely connects with it, studs 4 is axially disposed within the central position of stopper 2, and nut 3 is connected and fixed stopper 2 with studs 4 spirals.
Described stopper 2 inside evenly axially are provided with several fine porositys 2-1; Fine porosity 2-1 is convenient to the air of discharge pipe inside, and zinc liquid can not reflux.
During use each parts installed and fixed and finish, the steel pipe that assembles is put into the high temperature galvanizing flux, tube interior air expanded by heating, to two ends extruding stopper 2, air emits from the 2-1 of fine porosity, and zinc liquid can not reflux, and tube wall can be by not zinc-plated.
The utility model is simple in structure, and is easy to use, and when zinc-plated, inside pipe wall can not plate zinc, saves cost, cuts down the consumption of energy, and reduces and pollutes, and improves the sticking power of liner copper pipe and roller coating plastic layer, prolongs the work-ing life of pipe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of embodiment two.
Embodiment:
Embodiment one: with reference to Fig. 1, this embodiment is by the following technical solutions: it is made up of stopper 2, nut 3 and studs 4, stopper 2 is arranged on steel pipe 1 two ends and closely connects with it, studs 4 is axially disposed within the central position of stopper 2, and nut 3 is connected and fixed stopper 2 with studs 4 spirals.
Described stopper 2 inside evenly axially are provided with several fine porositys 2-1; Fine porosity 2-1 is convenient to the air of discharge pipe inside, and zinc liquid can not reflux.
During use each parts installed and fixed and finish, the steel pipe that assembles is put into the high temperature galvanizing flux, tube interior air expanded by heating, to two ends extruding stopper 2, air emits from the 2-1 of fine porosity, and zinc liquid can not reflux, and tube wall can be by not zinc-plated.
Embodiment two: with reference to Fig. 2, this embodiment is with the difference of embodiment one: its stopper 2 inside are provided with gas barrier 5, described gas barrier 5 is made up of bead 5-1, spring 5-2, gas barrier main body 5-3 and venting hole 5-4, bead 5-1 is connected with the end of spring 5-2, the other end of spring 5-2 is connected with gas barrier main body 5-3, and venting hole 5-4 is arranged on piston 5-3 inside.Other composition is identical with embodiment one with annexation.
When zinc-plated, tube interior air expanded by heating, to two ends extruding stopper 2, its inner bead 5-1 moved laterally after the gas barrier 5 of stopper 2 inside was squeezed, and venting hole 5-4 discharges the tube interior air, after treating that the tube interior air drains, spring 5-2 promotes bead 5-1 forward, and pipe seals once more, because the density of galvanizing flux is greater than air, zinc liquid can not produce backflow phenomenon, so tube wall can be by not zinc-plated.
This embodiment is simple in structure, and is easy to use, and when zinc-plated, inside pipe wall can not plate zinc, saves cost, cuts down the consumption of energy, and reduces and pollutes, and improves the sticking power of liner copper pipe and roller coating plastic layer, prolongs the work-ing life of pipe.
