Do not constitute the welding surface for being connected on valve seat, and two outer end faces of valve seat are also respectively constituted for connecting two end pipes
Welding surface, in addition, end pipe is connected to by the big end of diameter on valve seat, and end pipe is welded on by way of sweat soldering
The both ends of valve seat, and backup washer is mounted between end pipe and valve seat in advance before welding；Currently, the welding process of PE valves
Generally include the cutting flat with of the welding surface that coaxial fixed, two end pipes of valve seat and two end pipes are connected with valve seat, welding surface adds
The pressurize welding process of heat and welding surface.
As shown in Fig. 2, current PE standard machines generally include workbench, it is fixedly connected on workbench and is useful for being clamped
The main clamping device of valve seat, and one is respectively equipped on the bench-top at left and right sides of main clamping device can left and right sliding
Secondary clamping device, the secondary clamping devices of both sides is respectively used to the end pipe of clamping homonymy, meanwhile, secondary clamping device can guarantee valve seat
It keeps being coaxially disposed with two end pipes, therefore, by heating welding surface that two end pipes of welding mechanism pair are connected with valve seat simultaneously
After heating, later, the welding surface of two end pipes can be made to be pressed against valve seat both ends by the end pipe of both sides simultaneously to one side slip of valve seat
Corresponding welding surface on, to make two end pipes fully weld together with valve seat；And current heating welding mechanism is typically
It is arranged on the workbench on rear side of secondary clamping device and main clamping device, and it is to slide back and forth to be connected to work to heat welding mechanism
On platform, therefore, and when needing to heat end pipe and valve seat, heat welding mechanism energy forward slip a distance, and make plus
Heating head in thermal weld mechanism sticks on the corresponding welding surface of end pipe and valve seat, to be heated, and works as heating work
After, heating welding mechanism can be reset to again on rear side of secondary clamping device and main clamping device；The cloth of the heating welding mechanism
It sets and the shortcomings that mounting means is increased the volume of PE standards machine in the horizontal plane, to reduce the utilization of workshop
Secondly rate is unfavorable for arranging other devices in PE standard machines.
