Detailed description of the invention
As shown in Figures 1 to 4, a kind of stainless steel joint for pipeline includes: be provided with the combustion of outlet pipe joint end 201
Steam stove outlet pipe 2, is provided with the extension tube attached 3 of adapter sleeve clamping projection 301;On described gas furnace outlet pipe 2 also
Being provided with the externally threaded adapter sleeve 7 of band, described extension tube attached 3 is provided with tapped adapter sleeve 5, outside described band
The adapter sleeve 7 of screw thread and tapped adapter sleeve 5 can connect by matching thread;The externally threaded company of described band
Female connector 7 carries out spacing by outlet pipe joint end 201;Described tapped adapter sleeve 5 passes through adapter sleeve
Clamping projection 301 carries out spacing;Connect with extension tube attached 3 after gas furnace outlet pipe 2 bending.
The change of gas furnace water outlet direction realizes by being bent by gas furnace outlet pipe 2, this reality as shown in Figure 2
Executing example is to connect with extension tube attached 3 after gas furnace outlet pipe 2 90-degree bent, so there is no need to weld
(being realized by two water pipe welding manners as it is shown in figure 1, existing gas furnace changes water outlet direction), the most not
There will be intercrystalline corrosion causes water pipe to leak.The diameter of described outlet pipe joint end 201 end is more than outlet pipe
Joint end 201 is with the junction diameter of gas furnace outlet pipe 2.Preferably outlet pipe joint end 201 is that end is straight
Footpath is more than the pyramidal structure of junction diameter.Described outlet pipe joint end 201 and gas furnace outlet pipe 2 one
(also can split arrange) be set as it is shown on figure 3, its implementation is: the end to gas furnace outlet pipe 2
Just can form outlet pipe joint end 201 with taper die punching press, during use, externally threaded for band adapter sleeve 7 is enclosed within
On gas furnace outlet pipe 2, then by taper die to gas furnace outlet pipe 2 end punching press, form water outlet
Pipe joint end 201, can play spacing effect to externally threaded adapter sleeve 7, again can 6, fitted seal circle
Sealing function.
The end diameter of outlet pipe joint end 201 is less than the internal diameter of tapped adapter sleeve 5;Described external
The front end of pipe 3 is provided with the adapter sleeve clamping projection 301 spacing to tapped adapter sleeve 5, described adapter sleeve
The front end of clamping projection 301 is provided with sealing ring joint end 302.Described adapter sleeve clamping projection 301 can be by squeezing
The tube wall forward ends thereof of extension tube attached 3 is become inverted U-shaped projection by pressure technique, an extension tube attached 3 front end reserved part again,
This part is used for carrying sealing ring 6 and constitutes sealing ring joint end 302, as shown in Figure 4.During use, will seal
Circle 6 is enclosed within sealing ring joint end 302, adapter sleeve clamping projection 301 carry out spacing, then will seal
Circle joint end 302 inserts in outlet pipe joint end 201, and sealing ring 6 is with the inwall of outlet pipe joint end 201
Joint, is screwed in tapped adapter sleeve 5 on the externally threaded adapter sleeve 7 of band, then screws, this
Time sealing ring be connected the set front end side wall of clamping projection 301, the outer wall of sealing ring joint end 302 and go out
The inwall extruding of water pipe joint end 201, it is achieved the sealing that gas furnace outlet pipe 2 and extension tube attached 3 are connected.
Sealing ring 6 is to be compressed in adapter sleeve clamping projection 301, sealing ring joint end 302 and outlet pipe clamping herein
Can ensure that the stability of sealing ring 6 between end 201, sealing ring 6 is (the most former with joint, 3 faces simultaneously
Coming joint, only 2 faces, as shown in Figure 1) sealing is tightr.
Gas furnace outlet pipe 2 end is stamped and formed out by outlet pipe joint end 201 by taper die, adapter sleeve
The tube wall forward ends thereof of extension tube attached 3 can be become inverted U-shaped projection, clamping by extrusion process by clamping projection 301
End, projection and positive stop end are all formed on outlet pipe and connecting tube by technique, it is not necessary to additional components,
Do so can ensure that the stability of connection, reduces the techniques such as fixing, welding so that whole scheme is implemented simultaneously
The simplest.
