Abstract
The utility model discloses an inner leakage check device for a valve body. The device comprises a tube body, wherein one end of the tube body is open, and the other end is detachably connected with an end cover; and a sealing device is arranged between the tube body and the end cover. The device disclosed by the utility model can be used for accurately and quickly detecting whether leakage exists in a cold air valve and a pressure equalizing valve on a cold air pipeline of a hot-blast stove.
Description
Technical field
The utility model relates to the inspection units that a kind of valve is revealed, and relates to specifically the slight inspection units leaked of a kind of hotblast stove supply air system valve.
Background technology
In blast furnace production, the height of hot blast wind-warm syndrome directly affects output and coke ratio, obtain the auxiliary facility normal operation that higher wind-warm syndrome just must guarantee hotblast stove.In actual production process, along with the come into operation prolongation of time of cold blast valve, equalizing valve and hot blast valve, sealing surface wear or valve plate pad foreign material can cause valve air leakage phenomena to occur, thereby when hotblast stove is alternately blown, fluctuation appears in the blast furnace blast.And when valve slightly leaks out, adopt the conventional sense means can not judge quickly and accurately air leakage parts, can't fix a breakdown in time, cause the stable and high yields to blast furnace to bring many unfavorable factors.Install and implement by this device, can accurate, errorlessly find air leakage parts, for next step fault, get rid of accurate foundation is provided.
The utility model content
The purpose of this utility model is to provide the undetected device of looking in a kind of valve body, and whether cold blast valve, the equalizing valve that by this device, can detect accurately and rapidly on the hot-blast stove cold air blast pipeline exist leakage.
To achieve these goals, technical solution of the present utility model is: a kind of valves leakage inspection units, comprise body, and body one end opening, the other end are removably connected with end cap, between body and end cap, are provided with tightness system.
The utility model valves leakage inspection units, wherein, connect by flange between described body and end cap.
The utility model valves leakage inspection units, wherein, the asbestos plate that described tightness system adapts for the cross section with described body.
After adopting such scheme, because the undetected device of looking in the utility model valve body comprises body, body one end opening, the other end are removably connected with end cap, therefore do not need to remove cold blast valve and equalizing valve, only need open that end cap can detect cold blast valve and whether equalizing valve exists leakage, testing process fast, accurately.
The accompanying drawing explanation
Fig. 1 is the undetected structure iron of looking into device in the utility model valve body;
Fig. 2 is the undetected use structure graph of looking into device in the utility model valve body.
Embodiment
As shown in Figure 1, in the utility model valve body, the undetected device of looking into comprises body 11, body 11 1 end openings, the other end are removably connected with end cap 13 by flange 12, be provided with the asbestos plate 15 for sealing between body 11 and end cap 13, asbestos plate 15 is identical with equal and opposite in direction, the shape of body 11 cross sections.
As shown in Figure 2, the cold air duct 02 of hotblast stove 01 is provided with cold blast valve 03, the both sides of cold blast valve 03 are communicated with by pressure-equalizing passageway 04, pressure-equalizing passageway 04 is provided with equalizing valve 05, during use, the undetected body 11 of looking into device in the utility model valve body is welded between cold blast valve 03 downstream and equalizing valve 05, and by cold blast valve 03, equalizing valve 05 is all closed, when finding that there is the small leakage phenomenon from instrument and can't judge cold blast valve or equalizing valve again, remove the bolt between flange, open end cap 13, take out asbestos plate 15, hand is put in to body 11 to pressure-equalizing passageway 04, judge and leak out from equalizing valve 05 direction or cold blast valve 03 direction.After checking out, asbestos plate 15 is padded, cover tightly end cap 13 and get final product.
The above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering technical personnel in this area make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
