Description

A kind of dedicated unit leaked for handling Blast Furnace Throat Ventilation Valve

Technical field

The utility model category blast-furnace technique field, more particularly to a kind of for handling the special of Blast Furnace Throat Ventilation Valve leakage Use device.

Background technique

Bleeding valve is blast furnace roof key equipment, is located at blast furnace highest point, and general blast furnace roof is respectively arranged with three phases The diffusion valve of same specification.Diffusion valve is in close state usually, when blast furnace needs to occur the emergencies such as high pressure in damping down or furnace When, hydraulic cylinder, which is operated, in Central Control Room by operative employee opens the valve.But after diffusion valve emergency opening when closed, because of sealing surface It is mingled with accident to leak the coal gas caused by foreign matter or sealing ring Local Cracking, and once a leak occurs, is wound by cramming, jack is drawn Etc. conventional treatments poor effect, the time is long and is band gas operation, and security risk is very high.It does not block up for a long time, blast furnace roof Medium is raw coke oven gas, contains a large amount of dust inside coal gas.Dust high pressure sprays, and the more can blow the more big by leak source finally can only blast furnace Sealing ring is replaced in damping down processing, and damping down processing is at least 6 hours or more general, very big to Influence of production.

Existing processing mode includes 1, crams leakage point using asbestos cord leaching bath of glass, and 2, sealing surface wound using adhesive plaster, 3, valve deck etc. is tensed using jack.But because medium is high pressure raw coke oven gas in valve, pressure is high and contains a large amount of dust, and valve Position is special, is tensed using jack also because stress point is difficult to control, effect is undesirable.Handle overlong time, leakage position meeting The more blow the more big until processing failure, blast furnace can only damping down processing.Sealing ring is replaced, blast furnace needs damping down 6 hours or more, reduces iron Aquatic products amount is more than 1400 tons, very big to Influence of production.

Summary of the invention

The technical problem to be solved by the utility model is to provide for it is a kind of for handle Blast Furnace Throat Ventilation Valve leakage Dedicated unit, it is undesirable to solve existing processing mode effect, handles overlong time, cause leakage position the more can blow the more big until Processing failure, blast furnace can only damping down processing the problem of.

It is put the technical scheme adopted by the utility model to solve the technical problem is as follows: providing one kind for handling blast furnace roof The dedicated unit of valve leakage, including check lock lever and screw rod are dissipated, wherein the check lock lever lower end is equipped with eave tile, for catching on diffusion valve Flange on valve seat, the check lock lever upper end are equipped with horizon bar, and the horizon bar is equipped with elongate holes, for installing and adjusting Screw rod, the screw rod lower end are equipped with long nut, and for withstanding sealing surface, the screw rod upper end is equipped with clamp nut, passes through adjusting Clamp nut makes long nut compress sealing surface.

The further technical solution of the utility model is that the eave tile upper end is plane, for convenient and lip fits.

The further technical solution of the utility model is to set on the horizon bar there are two long nut, and two long spiral shells Distance is adjustable between mother.

Beneficial effect

The entirely autonomous design of the utility model handles light and fast, as long as discovery, sealing surface are mingled in time for diffusion valve leakage Foreign matter is little or sealing ring notch is little, use is a set of, at most two sets can handle and not leak completely, then wait until the later period Sealing ring is replaced again when blast furnace plan damping down, is not had any impact to blast fumance.

Specific embodiment

The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen It please the appended claims limited range.

Embodiment 1

As depicted in figs. 1 and 2, a kind of for handling the dedicated unit of Blast Furnace Throat Ventilation Valve leakage, including 1 He of check lock lever Screw rod 2, wherein 1 lower end of the check lock lever is equipped with eave tile 3, for catching on the flange 5 on release valve base, on the check lock lever 1 End is equipped with horizon bar 4, and the horizon bar 4 is equipped with elongate holes, is equipped with for installation and adjusting screw rod 2,2 lower end of screw rod Long nut 6, for withstanding sealing surface 7,2 upper end of screw rod is equipped with clamp nut 8, makes long nut 6 by adjusting clamp nut 8 Compress sealing surface 7.

3 upper end of eave tile is plane, is bonded for convenient with flange 5, is set on the horizon bar 4 there are two long nut 6, And distance is adjustable between two long nuts 6.

In actual use:

1,10 points of the morning of January 9 or so in 2014, iron-smelter 2# blast furnace will after sharply increasing because going out pipeline, press in furnace 2# bleeding valve opens.Pressure release late gate is voluntarily closed, and checks that discovery sealing surface is smoldered after closing, leakage gas.Subsequent inspection It repairs unit to take plug to fill out always, coat and handled, but effect is undesirable, coal gas cannot be closed always.Prepare second day blast furnace Damping down replacement in 6 hours sealing.After secondary designs at the beginning of 9 points process covering device use up at night, 10:20 points are disposed, and coal gas is thorough It does not leak at bottom.Avoid generational loss caused by second day damping down processing of original plan.

2,7 points or so of 15 morning May in 2014, iron-smelter 1# blast furnace periodical repair terminates multiple wind when closing bleeding valve, 2# Diffusion valve turn-off transient, the gas leakage of sealing surface part is larger caused by being mingled with plaster etc. because of valve bonnet seal face, first uses repeat switch one After secondary valve, but still gas leakage, after being pressed from both sides above using the grip device of designed, designed processing afterwards, local leakage point is thoroughly compressed It blocks, avoids the secondary damping down processing of blast furnace.

Above-mentioned two are subsequent, and on 06 11st, 2015, our factory 2# blast furnace 1# diffusion valve, October 24 in 2015,1# blast furnace 3# Diffusion valve, the 2# blast furnace periodical repair of on February 26th, 2016 terminate, and the accident to leak the coal gas of similar situation occurs for 3# diffusion valve etc., makes With being all effectively addressed after the device.
