Background technique
In industrial production, particularly in technical innovation, upkeep operation, often run into and in existing common-use tunnel, process pipe, increase the arm operation, conventional way is after stopping production, media discharge in the process pipe is clean, with the operations such as dismounting, replacing or welding of carrying out again pipeline valve behind air or the nitrogen replacement.But because a variety of causes, stopping production operation cost is too high, and the activity duration is long, and expense is high or can't satisfy operating condition for a long time and have to adopt unconventional method, pipeline the is in operation above-mentioned tap operation of enforcement that Here it is.
At present, the pipeline press and open holes has obtained being widely used, and technology is relatively ripe.Be " hole drilling device for pipeline with pressure " utility model patent of 201020559013.X such as application number.General step is: the one, and selection will pick out the cutting back of branch line caliber, and cutting back one end is welded with the footpath flange, and the other end is welded on female pipe of wanting perforate; The 2nd, install one with the footpath gate valve at the cutting back flange, gate valve is all opened; The 3rd, install the perforate professional equipment at the gate valve flange and carry out the perforate operation.After at first that cylinder cutter, company's case and perforator assembling is intact, be coupled on the flange of gate valve, and pressure testing is airtight without leaking, and can carry out the perforate operation, the cylinder cutter stretches into after by gate valve gradually, after female tube wall cutting thoroughly, withdraw from a cutter in the other direction, take simultaneously the tube wall part that cuts away out of, after falling back on gate valve always, then close gate valve, unload tapping equipment, the perforate end of job.To increase branch pipeline newly be connected on the gate valve this moment, open valve, but just normal operation input.
There are certain narrow limitation in existing press and open holes facility and method for the female pipe of minor diameter, the female pipe of General Requirements diameter will be more than 40 millimeters, and the arm diameter that connects is less than female pipe diameter, sometimes have to be with simultaneously and press off two holes in order to satisfy the arm traffic requirement, picking out that two minor diameter arms remerge is a major diameter arm.
Summary of the invention
In order to solve the narrow limitation that exists in the prior art, the utility model provides a kind of drilling under pressure of pipeline holder device, this device comprises: the cylinder tubing consistent with the female tubing matter of press and open holes, the length of cylinder tubing is greater than the female pipe of press and open holes external diameter, the cylinder pipe internal diameter is greater than the female pipe of press and open holes external diameter, cylinder tubing one end is welded with the latus rectum flange, pipe cap of the other end welding of cylinder tubing; The latus rectum flange is used for installing gate valve.
Further, gate valve is provided with the gate valve flange, and this flange is used for installing the press and open holes machine.
Further, weld the undergauge flange after cylinder tubing one end connects a reducer, this undergauge flange is used for being connected with gate valve again.
Further, along diametric(al) a circle is set in cylinder tubing neutral position and pierced cylinder tubing, the circle hole dia is consistent with the female pipe of press and open holes external diameter; Cylinder tubing cuts open cylinder tubing along cylinder tubing diametric(al) and is divided into two to justify the center, hole, the cylinder tubing that is divided into two wraps in to be wanted on the female pipe of the press and open holes correct position, the cylinder tubing that is divided into two is fitted as a whole again according to the orientation before cutting open, cylinder tubing fitting part welds together.
Further, mother being managed perforate is connected to branch pipeline on the gate valve afterwards.
Compared with prior art, use advantage and effect behind the utility model holder device:
1, the utility model support makes existing press and open holes machine satisfy the branch pipeline that picks out various different sizes at female pipe of all size diameter, particularly opens relatively bigbore branch pipeline at little female pipe;
2, the utility model support can make the press and open holes machine of ting model once leave the perforated area of twice (in the both sides of pipeline), can satisfy the branch pipeline that picks out large specification on the female pipe of large format diameter, reduce the operation easier of press and open holes and to the specification requirement of perforate facility;
3, by the job area of the existing perforator of the utility model stent expansion, suitable on-the-spot actual job spatial requirement.
