There is snap ring silk braid copper packing 9 between snap ring silk braid 8 and radial through-hole.
Brush 22 is welded in the stifled assembly placement region lower end of plug, for removing the iron filings that a knife surface is attached to（Clast）,
Simultaneously iron filings are stopped to enter inside threeway.
During cylinder knife is retracted, rotary cylinder knife can remove the iron filings being attached on a knife, the brush of brush 22
Hair 17 is remained to be contacted, such as can keep contacting 3mm always with cylinder knife.
Three 20mm × 5mm ring-shaped grooves 2, it is ensured that cutting generate iron filings be trapped in ring-shaped groove 2, avoid iron filings into
Enter inside threeway.
Operation principle is：
Multiple nuts and stud 20 are unclamped when trepanning operation, unload blind flange 19, remove snap ring silk plug 7, recruitment
Tool rotation snap ring adjustment screw 6 drives hook nut 5 to exit snap ring 4 outward, and snap ring 4 is disengaged with plug blocking ring slot 30, and it is stifled total to take out plug
Into upper guard board 27 and lower 24 end of backplate being welded on 26 line of standpipe, 25 axis of take over is vertical with standpipe 26, and cylinder knife is stretched into and is connect
In pipe 25, iron filings are removed on 22 polish-brush cylinder knife surface of brush in Tapping procedures, and after the completion of plugging holes, installing stopper blocks up assembly, inwardly
Means of press seals pearl 14 makes central through hole block up through-hole with plug plug wire and connects, and is conveniently put into plug stifled 12, and rotation snap ring adjustment screw 6 drives
Hook nut 5 inwardly pushes away snap ring 4, and snap ring 4 is caught in plug blocking ring slot 30, and clamping plug blocks up 12, and metal wound gasket 21 is padded in flange 3 and flange
Between lid 19, nut is installed and stud 20 fastens three-way body 1 and blind flange 19.
Threeway plug blocks up 12 placement region lower ends welding brush 22, and 17 height 13mm of bristle during cylinder knife is retracted, is brushed
Son 22 is located at lower section, and 17 end of bristle contacts always with cylinder knife, and rotary cylinder knife can make under the iron filings being attached on knife removing
Come, fall into three ring-shaped grooves 2, so as to reach iron filings prevent from entering threeway snap ring mechanism, inside sandwich valve, stifled 12 rest areas of plug
The purpose in domain ensures being smoothed out for horizontal bore.
