Power pump, water under high pressure is injected into the raised hydraulic pressure cavity of diaphragm, being pressurized to makes the operating pressure needed for ring film deformation, pressurize
Certain time, diaphragm is formed on ring film raised；
After 3rd step, closing presure pump, and pressure release draining, pressure pump joint is unloaded from high pressure water injection mouthful, then will
Body left end sealing blocking plate is backed out from body plugging plate mounting seat, and body cavity plugging plate is taken from the inner chamber of valve seat
Go out, diaphragm welding capping is screwed into body plugging plate mounting seat and ring film is compressed；
4th step, capping will be welded with diaphragm and the body of the raised ring film of diaphragm is formed it is placed on circular seam welding
Clamped on machine tooling platform, adjust welding parameter, ring film is welded on valve seat, ring is formed between ring film and valve seat
Shape weld seam；
5th step：The body for completing welding job is removed from circular seam welder tooling platform, the right-hand end of valve seat is blocked
Sealing, injects water under high pressure in the inner chamber of valve seat, keeps certain pressure, checks the circular weld between ring film and valve seat
Place, which whether there is water droplet, to be oozed out, and group welding piece is qualified if being oozed out without water droplet.
It is easy that the making frock of the present invention is realized, simple to operate, thoroughly solves the raised processing problem of diaphragm, makes diaphragm
Surface substantially increases diaphragm and valve seat combination and welding precision from machining damage, shortens processing assembling cycle.
Brief description of the drawings
Fig. 1 is the structural representation of the group mounted welder of the present invention；
Fig. 2 is the valve seat 2 of the present invention and has formed the structural representation of 3 groups of postweldings of ring film of diaphragm projection 13；
Fig. 3 is that the valve seat 2 welded to group carries out the structural representation of weld seam infiltration test.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
