The pipeline does not stop loses the opening, the trap series equipment is composed of the main engine and the auxiliary engine two kind of seies, the main engine series is by the opening machine, the trap, the hydraulic pressure stands with the under tamper four kind of different functions, the different model and the specification equipment corresponds mutually necessary is composed. The auxiliary engine is by the continually box series (by-pass opening case, trap opening case, seals off case, under to stop up box, the opening knife series(by-pass opening knife, trap opening knife), to clamp the plate vlve series, the trap tube series with the caliber which corresponds to be composed continually), it is (opens by-pass hole or trap hole) according to the different operating type and the work caliber matches the different main auxiliary engine. The user may refer to the necessary table according to need to select.
The PE pipeline does not stop loses the opening trap equipment to be suitable in the urban PE fuel gas loses the tubing nema network’s construction work. Mainly applies in presses the movement in the belt gas rangeon the PE pipeline pipe network meets the branch, affixes or replaces the valve, the replacement length of pipe, the pipeline to re-route and to transform, as well as the service, the emergency repair, rush to deal with an emergency and construction works and so on processing pipeline breakdown, avoids the economic loss which and the adverse effect which stops because of construction work loses creates to the social product life, eliminated the biography to lead is mad the operating type the safe hidden danger.
