unscrew the valve, which two customs clearance on the six angle body which two pass?
When the three-way valve is opened, the three directions are turned on and off, and the direction of the through body is communicated with the charging small valve, and the direction of the connecting pipe is not through.
Tube expansion, the annealing of copper pipe into the corresponding aperture, extending the length of pipe clamp with the diameter varies, large diameter copper tube expansion, length should be a little big, small diameter tube, tube length is smaller, with 8 for copper, a bulging the tube length is about 10mm, tighten the clamp nut at both ends of the copper pipe which is firmly clamped, insert the required diameter of the pipe expanding head, slowly rotating clockwise along the screw expander, the expansion to the required length.
The three link is open and everything is connected.Two brass butt, you will need a brass insert another piece of brass, then often need to end is inserted into the pipe diameter swell, so that the other can fit into the copper pipe, the only way to make the two copper welding firm, and not easy to leak, the role of tube expander is needed for different types of copper tube expansion.
