Abstract
The utility model relates to a pressurized device for forming holes on pipelines. A hole forming device penetrates through a narrow-mouth screw, and a handle of the hole forming device is fixedly connected at the tail end of the narrow-mouth screw; and a left side flange, a brake valve, a right side flange and a gland packing press flange are sequentially installed on the narrow-mouth screw. The pressurized device for the forming holes on the pipelines has the advantage of forming circular holes on running pipelines in the mode of mechanical cutting under the sealing state. When branch pipes need to be additionally installed on in-service pipelines, the device can accomplish the task of safely and efficiently modifying old pipelines in an environment-friendly manner, without influencing the normal conveyance of the pipelines.
Description
Technical field:
The utility model relates to a kind of pipeline construction instrument, particularly a kind of pipe pressurized boring device.
Background technology:
In the middle of shop equipment maintenance, the time regular meeting problem that the energy medium pipeline increases bypass appears, and the medium Trunk Line is stopped transport, pressure release needs the long time, seriously influence carrying out smoothly of producing, and has reduced operating efficiency.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of pipe pressurized boring device, this device changed stopping transportation, step-down that the pipeline on-line maintenance exists, diffuse, employ traditional operating type such as naked light, avoid operating risk, improve security, make maintenance promptly economical again rapidly reliable.
As above design, the technical solution of the utility model is: a kind of pipe pressurized boring device is characterized in that: hole making drill is passed thin mouthful of leading screw, and the hole making drill handle is fixed in thin mouthful of leading screw tail end; On thin button leading screw, left side flange, gate valve, right side flange and airtight and watertight padding differential are installed successively.
Above-mentioned hole making drill handle is fixed in thin mouthful of leading screw tail end by bolt.
The utility model has the advantages that: this device processes circular port in the machine cut mode on in-service pipeline under air-tight state.When the labour pipeline need install arm additional, can adopt this device under the situation of the normal conveying that does not influence pipeline, safely, efficiently, environmental protection to finish old pipeline modification work.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1-medium Trunk Line; The 2-pipeline; The 3-flange; The 4-gate valve; 5-carefully detains leading screw; The 6-nut; 7-airtight and watertight padding differential; The 8-handle; 9-handle bolt; The 10-hole making drill.
The specific embodiment:
As shown in the figure: a kind of pipe pressurized boring device, pass thin mouthful of leading screw with hole making drill, and the hole making drill handle be welded on the leading screw tail end; On thin button leading screw, left side flange, gate valve, right side flange and airtight and watertight padding differential are installed successively.
Use of the present utility model is:
1, at first to make the pressure size and the pipeline wall thickness of medium Trunk Line clear, determine to need to connect caliber, the material of bypass branch; Be ready in advance simultaneously that (such as being connected bypass is DN20 with valve than the pipe fitting that connects the high specification of bypass line, then select pipe fitting and the valve of DN25 for use), needing position of opening to mark the line of exoculation threeway then, confirm by calculating, with the tube wall suitable thickness of position partial cut of ruling, guarantee that the Trunk Line medium do not reveal with cutoff wheel.
2, in advance the device of illustrated blocks is connected, then encrypt packing material and airtight and watertight padding differential, hold with bolt both sides, guarantees that medium do not reveal; Then perforate size is as required selected hole making drill up to specification, and the handle of hole making drill is welded on an end of leading screw, and bypass line and medium Trunk Line connecting portion are welded, and flange on the left of installing installs gate valve, and the gate valve opening is got to maximum; The pipe pressurized boring device that has welded hole making drill then is installed.
3, knock the bolt of handle location with boosting-rod rotation and cooperation hand hammer, the former exoculation threeway of Trunk Line position is opened, and rotary handle is taken out the flange place on gate valve right side, closing gate valve with this part pipe skin, remove pipe pressurized boring device, then reducing connects needs the pipeline of specification to get final product.
Points for attention: this device can not be used for inflammable and explosive pipelines such as oxygen, coal gas, natural gas, can be used for pipelines such as water, compressed air.
Claims (2)
1. a pipe pressurized boring device is characterized in that: hole making drill is passed thin mouthful of leading screw, and the hole making drill handle is fixed in thin mouthful of leading screw tail end; On thin button leading screw, left side flange, gate valve, right side flange and airtight and watertight padding differential are installed successively.
2. pipe pressurized boring device according to claim 1 is characterized in that: above-mentioned hole making drill handle is fixed in thin mouthful of leading screw tail end by bolt.
