Abstract
The present invention aims at providing technological method of connecting thin wall stainless steel pipes so as to make thin wall stainless steel pipe used for water pipeline. The technological scheme of the present invention includes to make notches for sealing at end of stainless steel pipes, to paint sealing glue at and near the sealing notches, to jacket the union of thin wall stainless steel pipe around the painted area and fix, to roll the pipe and the union simultaneously two ring grooves near the sealing notches with double-roller press, and to heat the connecting point for the sealing agent to cure. The present invention is suitable for connection between thin wall stainless steel pipes.
Description
Technical field:
The present invention relates to the connecting means of stainless steel waterpipe and implement this connecting means De Roll depressor.
Background technique
Now has that technology relates to that water pipe connects connecting means and forms such as welding, flange connection, pipe joint connection.Stainless Steel Tube connects as adopting welding or flange, and its thickness of pipe wall must connect as adopting pipe joint more than 1.5mm, because of needs cut with scissors tooth on body, also must adopt the thicker pipe of tube wall by Shall.At present, Stainless Steel Tube Jia Ge Ang Expensive will popularize stainless steel pipeline and must adopt thin-wall stainless steel by Shall in water supply line, therefore, and the essential connecting means problem that solves thin-wall stainless steel.The existing bendable expansion joint of a kind of stainless steel, need on body, not cut with scissors tooth, can be used for the connection of thin-wall stainless steel, this joint adopts casting to make, tip side is provided with connection block, a seal ring is housed in the connection block, there is a pressure ring in the seal ring outside, the pressure ring outside has one with the port screw-internal thread fit of connection block and with the nut of shoulder hole, pipe arrangement need be provided with one groove when connecting on pipe arrangement, and in groove, place a C type circle, so that the nut with connection port fastens pipe arrangement by C type circle, this joint overall structure heaviness, in the construction of laying pipeline along body of wall, need to dig than deep trench, be not easy to construction, and should connect the connection of genus knot that can be undone by a pull, there is the problem of threading off.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of device that is applicable to the method that thin-wall stainless steel connects and implements this method.
Technological scheme of the present invention is to make one groove as seal groove at the pipe latter end, at seal groove and both sides coating sealing compound thereof, an end of the pipe fitting that thin-wall stainless steel is made is enclosed within the zone of pipe coating sealing compound and gives fixing then, pipe fitting and pipe are extruded the chimeric circular groove of twice simultaneously with Shuan Gun Lun Roll depressor before and after the seal groove subsequently, the joint is heated make sealant cures at last.
The present invention is owing to adopt the method for coating sealing compound in the seal groove, and heating makes the sealing compound expansion curing become seal area, play the effect that anti-Vent leaks, being provided with the chimeric mutually circular groove of twice simultaneously on pipe fitting before and after seal area and the pipe combines closely pipe fitting and pipe, solved the problem that resisting longitudinal stretches, because the present invention implements easily, use for popularizing of thin-wall stainless steel to have positive meaning.
Description of drawings
Fig. 1 represents to adopt the pipe fitting and the pipe connection diagram of this connecting means connection;
Fig. 2 represents the roller structural representation;
Among Fig. 18 represents pipe fitting, 9 pipes, 10 seal grooves, 11,12 telescoping grooves; Among Fig. 21 table shows Roll depressor the upper half, half under 2 rollers, and 3 Roller wheel, 4 upper saw pulleys, the socket of 5 Roll depressor rotating spanners, 6,7 regulate the screw of depth of groove.
Embodiment
The external diameter difference of implementing best way of the present invention and be to select the internal diameter of pipe fitting 8 and pipe 9 is more than or equal to 0 and be less than or equal to 1dmm, making an annular groove at pipe 9 ends is seal groove 10, be enclosed within the zone of pipe 9 coating sealing compounds and give fixing at seal groove and both sides thereof coating sealing compound and with an end of pipe fitting 8 then, extrude twice and the chimeric circular groove of pipe at the regional seal groove 10 front and back Yong Roll depressors of pipe fitting 8 and pipe 9 interlockings in the pipe fitting appearance subsequently, to the joint heating sealing compound is solidified rapidly at last.Implementing roller that the present invention adopts is made up of two toxoplasms up and down, be roller the upper half 1 and following half 2, wherein the upper half inboard is provided with two running rollers 3 side by side, upper saw pulley 4 before and after following half inboard is provided with two, the roller toxoplasm back of two halves up and down is equipped with the socket 5 of deep hole as the roller rotating spanner, two toxoplasmatic external parts of half are provided with dress and close the hole about the roller, and the employing connecting bolt adjusting roller distance of half up and down is the degree of depth of may command roll extrusion groove.
Claims (2)
1, stainless steel pipe rolling connection method and roller, it is characterized in that the pipe latter end makes one groove and make seal groove, at seal groove and two Side coating sealing compound thereof, an end of the pipe fitting that thin-wall stainless steel is made is enclosed within the zone of pipe coating sealing compound and gives fixing then, pipe fitting and pipe are extruded the chimeric circular groove of twice simultaneously with Shuan Gun Lun Roll depressor before and after the seal groove subsequently, the joint is heated make sealant cures at last.
2, stainless steel pipe rolling connection method according to claim 1 is Ji the Roll depressor, Qi feature Shi Roll depressor is made up of two toxoplasms up and down, two running rollers are side by side established in the upper half toxoplasm inboard, former and later two upper saw pulleys are established in following half toxoplasm inboard, up and down the toxoplasm back all establish deep hole as spanner socket Roll depressor up and down two toxoplasmatic external parts be provided with dress and close the hole, dress closes the hole and debugs the joint bolt.
