Common tools for plugging construction with pressure:
A belt tensioner. It consists of three parts: a bracket with a jaw and a tension and cut. It is an indispensable tool to eliminate the flange leakage and to eliminate the leakage of the pipe wall by the method of entrainment. The utility model has the advantages of small size, light weight and large pulling force, greatly simplifying the construction procedure and speeding up the process of plugging with pressure.
Two and versatile Karan. It consists of a clamp and an adjusting screw with an injection hole. There are many specifications. The structure is simple, but widely used: 1., to remove or replace the flange bolts, used to tighten the flange. 2. in the flange plane to change the hole to inject sealant, as long as it can be stuck, without tapping, equipped with injection valve. 3. is the rapid elimination of the valve stuffing box leakage important tool.
Three. Charging drills. Drilling tools, drilling 10mm, compressed air as power, pressure 0.5 ~ 0.6MPa, speed 2000 ~ 3000r/min, in flammable and explosive devices, the use of extremely safe.
Four, micro picks. By using compressed air driven, reciprocating motion for high frequency, pressure 0.5 ~ 0.6MPa, there are two purposes: 1. in the fixture on the milled edge, reducing the gap between the fixture with the leak site; 2. is an important tool for flange wire containment method.
