Pad.
Preferably, the instrument connection end is flange arrangement.
The beneficial effects of the utility model are：Pipe portion connection end, valve seat and the instrument of the integral gauge stop valve connect
Connect end to be formed in one structure, there is no gap between three building blocks, particularly welded without possessed by typical welding structure
Seam, so as to reduce medium to outboard leak, the risk of leakage；Valve sealing face also will not be by Site Welding and heat treatment
Influence.The stop valve sealed reliable, reduce the risk of valves leakage；It is compact-sized, eliminate welding and non-destructive inspection of weld
Program, improve production efficiency.In addition, the pipe portion connection end of integral gauge stop valve is Saddle, it has reinforcement work
With without setting reinforcing pipe fittings directly can be welded with pipeline.
