Abstract
A connecting pipe device with a gas drilling hole is composed of a connecting pipe, a gate valve, a pushing mechanism, a piston and a blind plate. One end of the connecting pipe is connected with an operating main pipeline, and the other end of the connecting pipe is provided with the blind plate. The piston butting against the inside of the connecting pipe through the pushing mechanism is arranged inside the connecting pipe, and the gate valve is arranged on the connecting pipe perpendicularly. The connecting pipe device enables a new pipeline to be connected with the operating main pipeline, can guarantee safety of operational workers, and can not affect normal usage of other gas pipeline users simultaneously.
Description
Technical field:
The utility model belongs to a kind of city gas pipeline operation under pressure equipment, particularly a kind of band pneumatic drill hole connecting tube device.
Background technique:
At present city gas pipeline operation under pressure is usually used in following several situation: 1, put into operation for a long time when pipeline, pipeline break, bond open take place or need discarded enclosure portion pipeline because certain personal factor is damaged, new pipeline is connected in perforate again.2, the pipeline that has put into operation need cut the replace tubes segment interface.3, the new pipeline of installing need with the pipeline interface UNICOM weld job that has moved.
Traditional gas pipeline opening operation needs that gas pipeline is carried out step-down or the rear substitution of stopping the supple of gas or steam can be taken over weld job.The workmen will cut the pipeline with certain gaseous-pressure, weld or beat mouthful, so the workmen must be familiar with the safety technique of dangerous operation, and can construct after formulating careful band gas connection plan, could normal air feed after construction finishes.
Band aluminium hydraulic pressed connecting pipe method complex process, cost height, influence the normal air feed of most users in the pipeline section after the step-down, can not obtain needed combustion gas section, can only be used for low-pressure line and take over weld job, and the activity duration is long, operating process is loaded down with trivial details, construction is dangerous high, the workmen will work out careful band gas and take over welding scheme, need all departments such as fire-fighting peace skill to closely cooperate at the scene, prevent to enter air in original gas pipeline, prevent that the operating personnel from burning, poison or suffocate.
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 band pneumatic drill hole connecting tube device, this device can make new pipeline be connected with the main line that is moving, and can guarantee operating personnel's safety, not influence other burning lines user's normal use simultaneously.
As above design, the technical solution of the utility model is: a kind of band pneumatic drill hole connecting tube device is characterized in that: by connecting tube, gate valve, driving mechanism, piston and blind plate are formed; One end of connecting tube is connected with the main line that is moving, and the other end is installed blind plate, and connecting tube inside is equipped with by driving mechanism and is headed into piston in it, and gate valve is vertical with connecting tube to be installed.
Above-mentioned piston is packed in the connecting tube by push rod bolt and sealing gasket.
The utlity model has following advantage and good effect:
1. new user's pipeline of installing is taken over weld job with the main line that is moving by the user's pipeline that uses mounting strap pneumatic drill hole connecting tube device can disposablely finish new installation.
2. this device can make band gas adapter weld job arrangement and method for construction technology simple, can can directly on the connecting tube device of band pneumatic drill hole, be connected without flange under the band gas condition with the main line boring that is moving, and harmful gas is not leaked, and can guarantee operating personnel's safety.
3. can be used for high pressure and middle the pressure, and do not influence other burning lines user's normal use with underground pipelines boring connection and construction weld job.
Description of drawings:
Fig. 1 is the utility model installation process schematic representation;
Fig. 2 is that the utility model is installed the back schematic representation.
Embodiment:
As shown in Figure 1, 2: a kind of band pneumatic drill hole connecting tube device, by connecting tube 6, gate valve 2, driving mechanism 1, piston 5 and blind plate 3 are formed.One end of connecting tube is connected with the main line 7 that is moving, and the other end is installed blind plate, and connecting tube inside is equipped with by driving mechanism and is headed into piston in it, and piston is packed in the connecting tube by push rod bolt 4 and sealing gasket, and gate valve is vertical with connecting tube to be installed.
Operating procedure of the present utility model is:
1, at first carry out nitrogen replacement at the new user's pipeline installed and band pneumatic drill hole connecting tube device, the displacement back is new installs the pipeline nitrogen pressure and is less than main line with the fate row.
2, after installation connection gate valve and preparatory work are finished, carry out the electronic boring machine operation of connecting tube bore operation＜use〉boring finish after, withdraw from driling machine, close the connection gate valve, re-use driving mechanism piston is installed in the connecting tube with the sealing of push rod bolt, withdraw from driving mechanism and remove and connect gate valve, blind plate is installed.
Claims (2)
1. band pneumatic drill hole connecting tube device is characterized in that: by connecting tube, gate valve, driving mechanism, piston and blind plate are formed; One end of connecting tube is connected with the main line that is moving, and the other end is installed blind plate, and connecting tube inside is equipped with by driving mechanism and is headed into piston in it, and gate valve is vertical with connecting tube to be installed.
2. band pneumatic drill according to claim 1 hole connecting tube device, it is characterized in that: above-mentioned piston is packed in the connecting tube by push rod bolt and sealing gasket.
