Description
Technical field
The utility model relates to a kind of gas valve protective gear, the gas regulator door on especially a kind of iron and steel metallurgical industry hot blast stove, specifically a kind of leakage preventer of gas pipe line modulating valve.
Background technique
Iron and steel metallurgical industry provides the hot blast stove of wind-warm syndrome for blast furnace, for guaranteeing that blast furnace is used wind-warm syndrome level, during hot blast stove burning, use automatic optimizating system, fixed-amount-of-air, by regulating gas regulator aperture, control the size of coal gas amount, burn stove process need and uninterruptedly by gas regulator, regulate coal gas amount, hot-blast furnace temperature is grown steadily, cause gas regulator operation frequency too high, when burning stove almost always in switch running state, between modulating valve axle sleeve and sealed packing, will soon there is gap, coal gas will leak out from gap, cause environment gas concentration to raise, jeopardize worker's personal safety.
Summary of the invention
The purpose of this utility model, it is exactly the problem existing for solving prior art, and designed a kind of leakage preventer of gas pipe line modulating valve, by switch valve by yellow glycerine indentation sealing space, in seal space, be full of yellow glycerine, utilize the yellow glycerine in seal space to come gap between sealed-regulating valve axle sleeve and sealed packing, reach the object that prevents gas leakage.
The technical solution of the utility model is: a kind of leakage preventer of gas pipe line modulating valve, comprise the modulating valve being arranged on gas pipe line, modulating valve drives the aperture of transmission shaft regulating valve by external motor, described transmission shaft is fixed on axle sleeve base by axle sleeve, and the outside of described axle sleeve is provided with sleeve sealing case; Described sealed case comprises axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover; Described axle sleeve case sealing cover is provided with transport pipe and fuel delivery valve; In described sleeve sealing case, be full of sealing oil.
As preferably, described axle sleeve case sealing cover is connected with axle sleeve base, axle sleeve frame, bearing support by welding, axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover formation sleeve sealing case.
As preferably, described fuel delivery valve is connected with transport pipe by Luo line.
As preferably, described transport pipe is connected with axle sleeve case sealing cover by welding.
As preferably, described sleeve sealing case is square.
As preferably, described axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover are the steel plate that 0.5mm is thick.
Described transport pipe is outer Luo line, and fuel delivery valve is inner thread, and both interconnect by screw thread.
As preferably, described sealing oil is yellow glycerine.
The beneficial effects of the utility model can draw by such scheme: because an axle sleeve case sealing cover is respectively welded in the space surrounding at axle sleeve base, bearing support and axle sleeve frame up and down, original cavity is formed to a seal space, again by yellow glycerine by fuel delivery valve in oil transport pipeline indentation sealing space, in space, be full of like this after yellow glycerine, just can be by gap closing between modulating valve axle sleeve and sealed packing, not only stop the leakage of coal gas, guaranteed the Security of environment, and equipment is played to good lubrication, effectively extended the working life of modulating valve.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein, 1, axle sleeve base, 2, axle sleeve frame, 3, bearing support, 4, transmission shaft, 5, axle sleeve, 6, differential, 7, axle sleeve case sealing cover, 8, transport pipe, 9, fuel delivery valve, 10, yellow glycerine.
embodiment:
In order to understand better the utility model, below in conjunction with accompanying drawing, explain in detail mode of execution of the present utility model.
Embodiment: as shown in Figure 1, a kind of leakage preventer of gas pipe line modulating valve, comprises the modulating valve being arranged on gas pipe line, and modulating valve drives transmission shaft 4 to carry out the aperture of regulating and controlling valve by external motor.Transmission shaft 4 is fixed on axle sleeve base 1 by axle sleeve 5, and axle sleeve 5 is provided with differential 6, and the outside of described axle sleeve 5 is provided with sleeve sealing case; Described sealed case comprises axle sleeve base 1, axle sleeve frame 2, bearing support 3 and axle sleeve case sealing cover 7; Above sleeve sealing lid 7, weld one section of transport pipe 8, a switch fuel delivery valve 9 is installed above transport pipe 8, yellow glycerine 10 is passed through to fuel delivery valve 9 in transport pipe 8 indentation sealing spaces.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
