Description
Technical field
The present invention relates to the aerial cooler field, particularly, relate to a kind of device for plugging of aerial cooler plug.
Background technology
Aerial cooler be with surrounding air as cooling medium, the high-temperature technology fluid in the tube bank is cooled off or the equipment of condensation.Aerial cooler adopts aerial cooler to replace water cooler, and the cooling condensation that carries out medium not only can using water wisely, can also reduce water and pollute.In the cold exchange device of oil plant and petrochemical plant, aerial cooler becomes an indispensable kind equipment.Its range of application has comprised overhead oil gas and has condensed to the various different operating modes that gasoline, diesel oil, heavy oil and residual oil cool off.In industries such as chemical industry, electric power, metallurgy, aerial cooler is extensive application also.
The tube bank two ends of aerial cooler are connected by expanded joint or welding manner with the radiating tube header, in the radiating tube header outside plug are installed, and pipe plug opening is used for tube bank installation, maintenance, cleaning etc., and plug adds that sealing gasket is tightened onto the effect of playing sealing on the pipe plug opening.
In daily production operation process, the aerial cooler plug is to be threaded with the radiating tube header, at the connecting portion of plug and radiating tube header because the operation fluctuation is very easy to occur leaking.And because air cooler is for high temperature fluid being cooled off or the equipment of condensation, so when leakage takes place, can not make air cooler stop production to keep in repair.
For the plug to aerial cooler carries out leak stopping, those skilled in the art has done long-term and a large amount of practices.
A kind of common method of leak stopping is that the band pressure welding connects, and still, the medium that aerial cooler leaks is oily vapour, and the spark of welding can cause fire and blast, so the plug of aerial cooler is carried out leak stopping, it is infeasible welding this scheme.
Also there is the technical staff to adopt the mode of caulking to carry out pressure sealing, also can produces spark for fear of caulking, so will select explosion-proof calking tool.But find in practice, because plug is to be threaded with the radiating tube header, caulking can destroy to some extent to the technology of radiating tube header itself, and because very approaching between plug and the radiating tube header, it is very inconvenient to carry out the caulking operation, so the effect of caulking is often not good, occurs plug probably and leak again.
Thereby, need a kind ofly can not stop production, the plug leakage position of aerial cooler carried out safety and the device of leak stopping reliably under the not pressure release, the situation of not lowering the temperature.
Summary of the invention
At in the prior art recited above the aerial cooler plug being carried out the problem that leak stopping occurs, the present invention proposes a kind of device for plugging of aerial cooler plug, to be used for that the plug of aerial cooler is carried out safe and reliable leak stopping.
The invention provides a kind of device for plugging of aerial cooler plug, wherein, this device comprises sealant ascending pipe, support portion and housing, described support portion is used for fixing described sealant ascending pipe, the wall of described housing surrounds the space of an end opening, and an end of described sealant ascending pipe is communicated with described space and forms supporting construction with the top of housing.
Device for plugging according to aerial cooler plug of the present invention, the support portion can be placed on the radiating tube header of aerial cooler, housing is covered on the aerial cooler plug that takes place to leak form confined space on every side, the maintenance personal can inject the confined space that housing forms with sealant by the sealant ascending pipe then, make the tube bank internal pressure of plug leak and outside sealant pressure balance, solved the leakage problem of aerial cooler plug, can not stop production, not pressure release, plug leakage position to aerial cooler under the situation of not lowering the temperature carries out safety and leak stopping reliably.
